# **Abstract**

Advanced and emerging market economies have rapidly integrated into international capital markets and this growing globalization of financial markets has led to some important changes in the patterns of saving and investment across the world. The main goal of this paper is to test whether the cross-border asset trade has led to improvements in the intermediation of these savings—that is, foster development of domestic financial markets. The authors have collected annual information on financial market development, financial openness, and other control variables for a sample of 145 countries for the period 1974–2007. Controlling for the likely endogeneity of financial openness, the analysis finds that rising financial openness expands private credit, bank assets, and stock market and private bond market development, and generates efficiency gains in the banking system. However, the impact of financial openness on domestic financial development may depend on the level of institutional quality, the extent of investor protection, and the degree of trade openness. In general, rising financial openness will enlarge the size and activity of financial intermediaries, improve efficiency in the banking system, and contribute to deepen private bond markets in countries with moderate to high levels of institutional quality and investor protection as well as in countries with high trade openness.

# 1. **Introduction**

One of the most salient features of the global economy in the last decade is the rapid integration of advanced countries and emerging market economies (EMEs) to international capital markets. Lane and Milesi-Ferretti (2001, 2003, 2007a,b) have extensively documented a rapid increase in cross-border asset trade for both industrial economies and EMEs. The growing globalization of financial markets has led to some important changes in the patterns of saving and investment across the world: emerging market economies driven by emerging Asia and oil exporting countries have become net suppliers of savings while the United States is an absorber of global savings.<sup>1</sup> In addition to promoting transfer of technology and know-how as well as improving institutions, financial openness may foster productivity through its effects on the development of domestic financial markets (Kose, Prasad and Terrones, 2008).

The globalization of capital markets has deepened financial markets across industrial countries and emerging markets, thus generating tight linkages across several financial markets where asset trading (in bonds, stocks or currencies) among banks, corporations and governments has risen considerably. Cost of accessing funds in international capital markets has declined ostensibly, thus facilitating investment and entry to markets. Competitive pressures for innovation have arisen and savings have been mobilized in order to accumulate capital; thus, leading to higher growth rates (Levine, 2005). In spite of these developments, there is a great deal of heterogeneity in financial development across countries.

Figure 1 plots the average ratio of foreign asset holdings to GDP and the ratios of private credit and financial deposits to GDP for industrial and developing countries from 1974 to 2007. The share of private credit to GDP in industrial economies is, on average, more than three times higher than that of developing countries. The holdings of external assets as a share of GDP are, on average, 2.5 times higher in industrial countries.2 What explains the persistence of underdevelopment in the domestic financial markets? Our goal is to examine the relationship between financial openness and financial development.

> 1 Lane and Milesi-Ferretti (2007a, 2008) show that net external positions of EMEs have vastly improved, with emerging Asia and oil exporting countries while building up substantial creditor positions. They also document an important shift in the structural of external balance sheets: EMEs have undertaken massive reserve accumulation and raised their share of equity in total external liabilities while the US has heavily relied on debt.

International financial integration may lead to a faster development of domestic financial intermediaries through different channels. Financial openness may increase the depth and breadth of domestic financial markets and improve the efficiency of financial intermediation by eliminating financial repression and shifting interest rates to clearing-market competitive levels, thus reducing the cost of capital (Baldwin and Forslid, 2000). It may also improve the quality and availability of financial services in the domestic market by increasing the degree of bank competition and enabling the application of more sophisticated banking techniques and technology, which may improve efficiency by reducing the cost of acquiring and processing information on potential borrowers (Levine, 1996; Caprio and Honohan, 1999). Rising financial openness would lead to a more efficient financial system by displacing inefficient financial intermediaries and creating pressure for the implementation of reforms in the financial infrastructure so as to reduce problems of information asymmetry, adverse selection and moral hazard (Stulz 1999; Stiglitz 2000; Claesens _et al_ . 2001; Chinn and Ito, 2006).

Financial liberalization, as we argued above, may foster the better functioning of financial markets. However, it may lead to risky behavior by banks (Allen and Gale, 1999; Schneider and Tornell, 2004) and trigger boom-bust cycles in economies with imperfect capital markets (Tornell and Westermann, 2005). Agency problems may encourage borrowers to use bank loans to buy risky assets during lending booms and, the resulting bubbles may burst into banking crisis and recessions (Allen and Gale, 2000). Kaminsky and Schmukler (2008) find that financial liberalization in emerging markets generates short run tensions but provides a market stabilization role in the long run. They also argue that financial deregulation may not only trigger short run problems and crisis if it occurs in economies with weak institutions and agency problems but also long-run gains arise as financial liberalization deepens and institutions improve.<sup>3</sup> The effect of financial openness on domestic financial development may be ambiguous. In fact, it may depend upon some structural features of the domestic economy. Domestic financial systems would benefit from financial openness if they have a legal and regulatory framework that guarantees contract enforcement, the protection of property rights and good accounting practices. La Porta _et al_ (1997, 1998) argue that the efficiency of contract

> 3 Financial openness may be associated with volatile capital flows in the short run and rising vulnerability to external shocks, thus leading to a greater instability of the domestic banking system. If a banking crisis ensues, and as the economic undergoes a severe recession, default rates and non-performing loans increase. Foreign banks could cut lines of credit to domestic borrowers in times of crisis (Agenor, 2003).

enforcement and the treatment of creditors and shareholders are influenced by the origin of legal code. More specifically, they find that countries with _Common Law_ —as opposed to those with _French civil code_ tradition— tend to protect private property owners, have comparatively more efficient contract enforcement mechanisms and, hence, achieve higher levels of financial development. Mayer and Sussman (2001) find evidence that regulations concerning information disclosure, accounting standards, permissible practice of banks and deposit insurance have significant effects on financial development. Shallow stock markets usually exhibit low levels of shareholder rights (Levine, 1998, 2002; Claessens et al. 2002). Rajan and Zingales (2003) indicate that the joint opening of trade and capital accounts would promote financial development. They argue that elite groups with access to power in countries with trade and financial autarky have strong incentives to resist the development of a more transparent and competitive financial sector in order to prevent new entrants in their markets. In this context, interest groups would support the opening of trade and financial accounts if only they could take advantage of deeper local financial markets and draw resources from a more ample pool of funds, and generate new rents to counterbalance their loss of access to power.

The main goal of this paper is twofold. First, we test whether the increasing crossborder asset trade has led to improvements in the development of domestic financial markets —captured by increasing the size and depth of deposit money banks and other financial institutions as well as deepening stock and bond markets. Second, we examine whether this impact depends upon country-specific characteristics such as the degree of institutional quality, investor protection and trade openness. We collect annual information on financial market development, financial openness and other control variables such as GDP per capita, inflation, trade openness among others for a sample of 145 countries (of which 24 are industrial countries) from 1974 to 2007. We use the identification strategy developed by Faria et al. (2007) and Faria and Mauro (2009) to control for the likely endogeneity of financial openness in our financial development regressions.

Understanding the effects of higher cross-border asset trade on the development of financial intermediaries stock markets and bond markets is crucial due to the impact of financial market development on growth (Levine et al. 2000; Levine, 2005) and, especially, on the direction of capital flows and the persistence of global imbalances (Chinn and Ito, 2007; Gruber and Kamin, 2008). In a seminal paper, Rajan and Zingales (1998) find that _ex ante_ financial market development may help boost the _ex post_ growth of “external-financially-dependent” 4
sectors by reducing their cost of raising funds abroad. Guiso _et al_ (2004) argue that domestic financial market development still matters for growth even in economies that are highly integrated to world capital markets. Their example shows that domestic financial market development is still important to a country like Italy that has been fully integrated for the last 140 years. On the other hand, the under-development of domestic financial markets in developing countries could explain their excess external savings, the capital flow reversal and low interest rates in the United States. The direction of capital flows observed in the global economy is the result of weaker enforcement of financial contracts and shallow domestic capital markets that raises the cost of financing due to inefficiencies in channeling resources from savers to domestic investment. This prevents emerging market firms to borrow internationally to finance domestic investment, and limits the ability of EMEs to produce financial assets for global savers (Mendoza, Quadrini and Rios-Rull, 2007; Caballero, Farhi and Gourinchas, 2008; Smith and Valderrama, 2009a,b; Valderrama, 2008).

Our paper complements existing evidence that more intense financial linkages may lead to deeper domestic financial markets after controlling for the legal and institutional framework of the country. Chinn and Ito (2006) evaluate the linkages between capital account openness and financial development for a sample of 108 countries from 1980 to 2000. They find that financial openness contributes to deepening the stock markets in countries beyond a specific threshold level of legal and institutional development. Ito (2006) carries out an analogous exercise focusing on Asian economies and finds that the impact of financial openness on the depth of stock markets is enhanced in countries with lower levels of corruption and higher levels of rule of law and of bureaucratic quality. Baltagi _et al._ (2009) use four different datasets since the 1980s to test the linkages between financial openness and financial development. They find that: (a) trade and capital account openness may have a significant impact on financial development in countries that are relatively closed, and (b) trade and financial openness may be substitute mechanisms of promoting financial development rather than complements as suggested by Rajan and Zingales (2003).

Our research improves upon the evidence presented in Chinn and Ito (2006) and Ito (2006) by: a) presenting evidence for a sample period which is much larger than their dataset, b) presenting panel data evidence with outcome measures of financial openness that capture the degree of financial openness instead of the absence of restrictions on cross-border asset trade, c) instrumenting for financial openness with external instruments recommended by the recent 5
existing literature and d) jointly testing whether the institutional framework, investor protection and trade openness play a role in fostering the impact of financial openness on domestic financial sector development.

Our main findings suggest that domestic financial markets are enhanced by the higher integration of countries into world capital markets. In general, rising financial openness leads to deeper local capital markets by: (i) enlarging the size and activity of financial intermediaries (that is, generating an expansion in private credit, financial deposits and bank assets), (ii) improving the efficiency in the banking system, and (iii) contributing to the deepening of local stock market and private bond markets. These effects are economically significant in countries with moderate to high levels of institutional quality, investor protection and trade openness.

This paper consists of the following sections: Section 2 describes the data and methodology. Section 3 discusses our regression analysis and evaluates the role of the structure of external assets and liabilities in driving the impact of financial openness on domestic financial development. Section 4 discusses whether these different effects are driven by cross-country or cross-region differences in the level of institutional quality, the degree of investor protection, and the extent of trade openness. Finally, section 5 concludes and suggests further avenues for future research.

# **2. Data and Methodology**

This section describes the definition and sources of the data used for our empirical assessment and an outline of the econometric estimation technique used.

## **2.1 The Data**

We have collected annual data on financial depth, financial openness and other determinants of domestic financial depth (income per capita, inflation, openness, institutions, etc.) for 1974-2007 (our full sample period). The list of countries classified by region and the level of income is presented in Table A.1.<sup>4</sup> Our dependent variable aims to capture the level of _domestic financial development_ . Given the multiplicity of aspects surrounding the concept of domestic financial development we use a wide array of indicators developed by Beck, Demirgüç-Kunt and Levine (2000). We update

their database which contains information up to 2006 with information from the World Bank’s World Development Indicators (WDI) and the International Monetary Fund’s International Financial Statistics (IFS). These indicators of _domestic financial development_ can be grouped in 6 categories:

- (a) _Measures of (absolute and relative) size of financial intermediaries_ are captured by the assets of deposit money banks and assets of the financial system (deposit money banks and other financial institutions) as a percentage of GDP. We also include the ratio of deposit banks vis-à-vis the central bank assets and the ratio of liquid liabilities of a financial system to GDP.<sup>5</sup>

- (b) _The level of activity of financial intermediaries_ is measured as the private credit by deposit money banks (DMBs) and the extent of domestic credit to the private sector (undertaken by deposit money banks and other financial institutions). We call them _bank credit_ and _financial credit_ , respectively. They capture the financial intermediation with the private non-financial sector in channeling savings to investors. Note that all variables are expressed as a percentage of GDP in logs.

- (c) _Efficiency and structure of the commercial banking sector_ are measured by: (i) _overhead costs are_ the ratio of accounting value of the bank’s overhead costs as a share of its total assets. (ii) The _interest rate margin_ is the net interest revenue as a percentage of the commercial bank’s interest-bearing (total earning) assets. (iii) The _concentration of the banking system_ is proxied by the assets of three largest banks as a share of assets of all commercial banks.

- (d) The _depth of other financial institutions_ is approximated by the level of activity of insurance companies. We use the volume of life insurance premium and non-life insurance premium (i.e. life and non-life insurance penetration, respectively) as a share of GDP in logs.

- (e) _Stock market development_ . We use the stock market capitalization and the stock market total value traded to capture the level of activity or liquidity of domestic stock markets as a percentage of GDP in logs. We include the stock market turnover (ratio of the value

> 5 We should remark that liquid liabilities include currency in circulation plus demand- and interest-bearing liabilities of banks and other financial intermediaries. This is the broadest available indicator of financial intermediation (since it includes all financial sectors) and is a typical measure of financial depth (i.e. overall size of the financial sector without distinguishing financial sectors from between liability uses).

of total shares traded to average real market capitalization) and the number of listed companies in the stock exchange.

- (f) _Bond market development_ . We use indicators of the level of activity of domestic bond markets such as private bond market capitalization (private domestic debt securities issued by financial institutions and corporations) and public bond market capitalization (public domestic debt securities issued by the government) deflated by GDP in logs.

_Financial openness_ is measured as the ratio of foreign assets to GDP, foreign liabilities to GDP, and foreign assets and liabilities to GDP. To construct these ratios we use the data on foreign assets and liabilities from Lane and Milesi-Ferretti (2001, 2007a) and updated (at best) until 2007 with data from international investment positions published by the central banks. Note that holdings of foreign assets (and/or liabilities) imply the accumulation of holdings of assets (and/or liabilities) in foreign direct investment, portfolio equity, debt (portfolio debt and other investment), and financial derivatives.

To assess whether the hoarding of risky vs. riskless assets or the accumulation of equity vs. debt liabilities affects the development of domestic financial institutions, we decompose our measure of financial openness into equity- and loan-related foreign assets and liabilities. Equityrelated assets and liabilities comprise information on direct investment and portfolio equity assets and liabilities. Loan-related assets (or riskless assets) include debt assets and reserve assets while loan-related liabilities include debt liabilities and financial derivatives liabilities (for the few countries that report them).

Among the _control variables_ in our regression analysis we include: real output measured by the PPP-adjusted real GDP from Heston, Summers and Aten (2006), inflation (lagged) as measured by the average annual change in consumer price index (from WDI), and trade openness approximated by the real value of exports and imports as a percentage of GDP. We also include two categories of _exchange rate regimes_ from Ilzetzki, Reinhart and Rogoff (2008): _dual exchange rates_ and _freely falling exchange rates_ . The former variable is a binary variable that takes the value of 1 whenever there is a dual market and parallel market data is missing. The latter takes the value of one for countries that have the annual inflation of more than 40% of inflation or that experience currency crisis. The _level of institutional quality_ is measured by the index of political risk by International Country Risk Guide (ICRG) and includes information on corruption, rule of law, democratic accountability, bureaucratic quality, investment profile, 8
government stability, socio-economic environment, ethnic tensions, etc. We also collect information on the index of _investor protection_ which measures the strength of minority shareholder protections against misuse of corporate assets by directors for their personal gain. This includes information on the transparency of transactions (extent of disclosure), liability for self-dealing (extent of director liability), and the shareholders’ ability to sue officers and directors for misconduct (ease of shareholder suit index). The data is obtained from Djankov et al. (2008). Table A.2 presents a more detailed description of the sources of data for all the variables used in our econometric analysis.

# **2.2 Estimation Technique**

The proposed panel data regression faces two challenges for estimation. The first one is to control for the presence of unobserved period- and country-specific effects. The inclusion of period-specific dummy variables can account for the time effects while country dummies deal with country-specific effects. The second challenge is that financial openness is likely to be jointly endogenous with shocks to domestic financial market development; hence, we need to control for the biases resulting from simultaneous or reverse causation in our financial development equation.

Our regression equation of domestic financial development has the following specification: where our dependent variable, _FDit_ , is the measure of financial development of country _i_ in period _t_ . The matrix **_X_** it represents the matrix of explanatory variables, and _FO_ it is the measure of financial openness — _i.e._ our variable of interest. The matrix **_X_** it comprises information on the control variables for our financial depth regression equation (real output per capita, inflation, trade openness, and dummies for dual and freely falling exchange rates).<sup>6</sup> All the control variables are lagged so as to avoid likely reverse causality issues. _FO_ it also captures the degree of international financial integration of country _i_ in period _t_ as measured by the ratio of foreign assets to GDP, foreign liabilities to GDP, or foreign assets and liabilities to GDP.

> 6 Note that the selection of explanatory variables follows the empirical literature on the determinants of financial intermediation (Aggarwal et al. 2006; Baltagi et al. 2009; Chinn and Ito, 2006; Do and Levchenko, 2007; Huang, 2005; Huang and Temple, 2005; Ito, 2006)

9
> Our baseline regression (see Tables 3-5) assumes that γ _it_ = γ while γ _it_ ≠ γ in our expanded model (see Tables 6-10). In the latter assumption, the impact of financial openness on financial development depends upon the structure of external assets and liabilities, the level of institutional quality of the country, the degree of investor protection and the extent of trade openness.

It is highly likely that shocks to domestic financial development may have an effect on financial openness. Therefore, we need to find appropriate instruments for our variables of interest by following the strategy in Faria _et al._ (2007) and Faria and Mauro (2009) to instrument for financial openness. They select a broad range of potential determinants of the external capital structure of countries as measured by total foreign liabilities (as % of GDP), and a share of equity (portfolio and FDI) in total foreign liabilities. More specifically, they used the following instruments: a “narrow” definition of institutional quality (that comprises rule of law, corruption, a quality of bureaucracy and democratic accountability), the country’s initial size (the lagged value of PPP adjusted GDP), the legal origin of countries (La Porta _et al._ 1998), the area of country in logs, and the abundance of natural resources (as proxied by the share of primary exports in total merchandise exports). Our results are consistent with the findings in Faria _et al._ (2007) and Faria and Mauro (2009) where greater equity share in total liabilities is attained by larger countries with better institutional quality and greater reliance on natural resources. Countries with higher ratios of total foreign liabilities to GDP are smaller countries with better institutional quality, greater reliance on natural resources and with French civil code tradition. A greater share of debt in external liabilities is also achieved by smaller countries with lower levels of education attainment, poorer levels of institutional quality and lower reliance on natural resources.

# **3. Empirical Evidence**

This section describes the main results of our empirical analysis of the impact of financial openness on the development of domestic financial institutions (banks, stock markets, insurance companies and bond markets) for our sample period. We first describe the main statistics and present the basic correlation analysis, and then we carry on the analysis of our panel data regressions.

10
# **3.1 Basic Statistics and Correlation Analysis**

Table 1 presents the basic statistics on domestic financial development, financial openness and other control variables (trade openness, institutions and investor protection) for the full sample period. We report the averages of these variables not only for the full sample but also for the sub-samples classified according to the level of development of the economy and the income levels.

As expected, financial intermediaries are larger in high-income countries than in middleand low-income economies. On average, total assets in deposit money banks represent 73% of GDP in high income countries while they amount to 28% and 15% of GDP in middle- and lowincome economies, respectively. Liquid liabilities of the financial system represent approximately 68% of GDP in the average high-income country while it totals 36% and 23% of GDP in middle- and low-income countries, respectively. Bank credit and bank deposits are larger in high-income countries (both at approximately 60% of GDP on average) than in middle- and low-income countries (at an average of 25% and 14% of GDP, respectively). Banks are also more efficient in high income economies than in the other income groups as reflected by lower overhead costs, lower net interest margin and lower bank concentration. Stock and bond markets are deeper in high-income countries than in middle- and low-income economies.

Furthermore, industrial economies are more integrated to international financial markets than developing countries, and the divergences are even bigger when we focus on the accumulation of riskier assets (equity-related foreign assets) rather than riskless assets (loanrelated foreign assets). Developing countries tend to hold more international reserves as a percentage of GDP than industrial countries and this is mainly driven by reserve hoarding practices in middle-income countries.

Table 2 reports the panel correlation analysis for financial development and financial openness measures for the full sample period. The positive correlation between external foreign assets and measures of size and activity of deposit money banks and the financial system is always larger than that of foreign liabilities. This association is driven by positive coefficient of correlation between (size and activity of) financial intermediaries and equity-related (and loanrelated) foreign assets although the correlation with equity-related assets is larger.

Overhead costs and net interest margin are negatively associated to foreign assets and foreign liabilities. The correlation of these efficiency measures is stronger with both foreign assets and equity-related foreign assets (compared to loan-related foreign assets). Bank 11
concentration seems to have a weak correlation with our measures of financial openness. Highly-integrated countries to world financial markets —as measured by larger foreign assets and liabilities— display higher degrees of stock market capitalization and bond market capitalization.

# **3.2 Panel Regression Analysis: Baseline Regression Analysis**

We conduct our econometric analysis to test whether higher integration to international capital markets promotes the development of domestic financial intermediaries. Our dependent variable is the level of domestic financial development proxied by measures of activity and size of financial intermediaries (deposit money banks and other financial institutions), stock market and bond market development. Recall that the matrix **Z** _it_ represents the matrix of control variables and is conformed by the (log) level of output per capita, inflation, trade openness, and dummy variables for dual and freely falling exchange rates. Our interest is the extent of integration of domestic countries to international capital markets proxied by foreign assets and liabilities.

# **3.2.1 Least Squares Estimation**

Table 3 reports the coefficient estimate of _financial openness_ where we apply least squares to our baseline regression for measures of size, activity and efficiency of financial intermediaries. The control variables (output per capita, inflation, trade openness, dual and freely falling rates) are not reported in the table and our regressions include both country- and time-specific effects. Our estimates of financial openness are reported for the full sample and for the sub-samples of industrial and developing countries. Our findings are:

- 1) Private credit provided by banks and bank assets are higher in countries with rising foreign assets and liabilities while bank deposits appear to have no robust relationship with financial openness. There is no robust relationship between overhead costs and financial openness while there is a negative and robust correlation between net interest margin and financial openness. Bank concentration rises if countries are highly integrated to world capital markets.

- 2) Bank credit and bank deposits tend to rise among industrial countries with higher financial openness —especially with foreign assets as a percentage of GDP. The size of financial intermediaries, measured by either assets of deposit money banks or liquid

12
liabilities to GDP, is positively associated with the extent of financial openness of the domestic country. Net interest margin is negatively and robustly correlated with financial openness for industrial economies while overhead costs are negatively and significantly associated with financial openness (when the explanatory variable is foreign assets). Bank concentration does not show a robust relationship with measures of financial openness for developing countries.

- 3) Bank credit and bank deposits have a positive and significant relationship with foreign liabilities (as a ratio of GDP) for all countries, industrial countries and developing countries except and with bank deposit in industrial countries. Similarly, there is a positive and significant relationship with the size of financial intermediaries (assets of deposit banks and liquid liabilities). In most cases, a positive and significant link between financial openness and efficiency in financial intermediaries as shown as a negative association with lower spreads from overhead costs and net interest margin and with a higher concentration in banking activity.

Table 3 reports the least squares estimates of the financial openness coefficient for the regression of indicators of stock and bond market development as well as for the depth of other domestic financial institutions (insurance companies). We mainly find that:

- 1) Countries with a higher extent of financial openness tend to have deeper stock markets as proxied by their capitalization and trade value. The positive coefficient of stock market capitalization is significant regardless of the measure of financial openness and sample used. The result of the stock market value traded is mainly driven by industrial countries. The relationship between the number of listed companies and financial openness is negative and significant for industrial countries while it is positive and significant for developing countries.

- 2) Rising financial openness is associated to deeper private bond markets in industrial markets whereas this correlation is negative among developing countries. The correlation between financial openness and public bond market capitalization is not robust across sub-samples of industrial and developing countries.

- 3) The depth of life and non-life insurance is higher if countries are more integrated to world capital markets –as measured by foreign liabilities and foreign assets and liabilities. This is mainly due to the strong association in developing countries.

# **3.2.2 Instrumental Variables**

Table 4 presents the baseline regression results for three selected measures of financial development such as bank credit, bank deposit and stock market capitalization. We control for the likely endogeneity of financial openness with instruments such as real output, area of the country, institutional quality, natural resource abundance and dummies for legal origin (see the data description in appendix). Our regressions include country- and time-effects and the control variables show expected signs in our regression analysis as higher levels of financial market development proxied by higher banking credit and deposits and higher stock market capitalization are usually exhibited by countries with higher income per capita, more open to international trade and lower inflation and without either dual exchange rate market or freely falling exchange rates. The results for financial openness are: (a) Countries that are more integrated to world financial markets tend to have larger banking credit regardless of the measure of financial openness. (b) The impact of financial openness on bank deposits is not robust across measures of financial openness —i.e. it is not significant for foreign assets and negative and significant for foreign liabilities. (c) Rising financial openness tend to increase stock market capitalization. Evaluating the quantitative importance of our estimates we find that doubling financial openness — _e.g._ doubling foreign liabilities— would raise the ratio of bank deposits to GDP by 6.5% and the ratio of stock market capitalization to GDP by 25%.

Table 5 expands the results presented in Table 4 to all our measures of financial development (activity and size of financial intermediaries, banking efficiency, insurance penetration, stock and bond market development), measures of financial openness (foreign assets, foreign liabilities, and foreign assets and liabilities) and different samples of countries. Due to the limited space we only report the coefficient of financial openness.<sup>7</sup> _Activity of financial intermediaries_ . Financial openness has a positive and significant effect on bank credit and financial credit regardless of the measure of financial openness for both full sample and sub-sample of industrial countries. Rising financial openness does not have a robust effect on private credit in developing countries. Rising foreign assets have a positive and significant effect on bank deposits for industrial country while it has an insignificant effect for developing countries.

_Size of financial intermediaries._ The size of deposit banks proxied by their total assets to GDP rises with higher financial openness for both full sample and sub-sample of industrial countries. The results are qualitatively similar although statistically less robust for liquid liabilities of the financial system. The ratio of deposit money banks to central bank assets increases with higher foreign asset holdings, and it declines with higher foreign liability holdings. Note that this result holds for the full sample and among developing countries.

_Efficiency of financial intermediaries_ . We fail to find a robust relationship between overhead costs and financial openness in all samples although there is a negative and significant coefficient estimate for foreign assets for industrial and developing countries. Therefore, overhead costs decline in countries that accumulate higher foreign asset holdings even though net margin interests decline with deeper integration to world financial markets (regardless of the measure of financial openness and the sample of countries used). Banking systems with higher extent of financial openness tend to be more concentrated although the result is not significant for industrial countries (see Table 5).

_Stock markets_ . An increase in financial openness (regardless of the measure used) would raise the depth of stock markets as proxied by stock market capitalization and total value traded. This effect is robust to all samples in Table 5. Stock market turnover is, in most cases, positively influenced by higher financial openness. However, deeper integration to financial markets tends to have opposite effects on the number of listed companies in the stock market for industrial and developing countries. While it has a negative effect in the former sample, it has a positive effect with less robust in the latter sample.

_Bond markets and other financial institutions_ . IV coefficient estimates indicate that an increase in financial openness tends to raise the depth of private and public bond markets. For instance, doubling foreign liabilities would significantly decrease the capitalization of private and public bond markets by approximately 35% and 27%, respectively for all countries. Raising foreign liabilities among industrial countries would deepen the capitalization of private and public bond markets by by approximately 63% and 22%, respectively. For developing countries, doubling foreign liabilities significantly decrease private capitalization while they increase the public capitalization (although the effect is not statistically significant). Rising financial openness tends to increase the penetration of life insurance in the domestic country although it does not have a robust effect on non-life insurance in Table 5. Compared to Table 3, the Chinn-Ito measure of financial openness has a negative coefficient for non-life insurance.

# **3.2.3 Sensitivity of our Baseline Results**

We check the sensitivity of the coefficient estimate of financial openness in our regression analysis in two dimensions. First, we test whether our results may be driven or influenced by sharp variations in financial development variables that could be linked to lending booms, stock market bubbles and the collapse of financial prices. We investigate whether our baseline regression results are distorted by data outliers. In this case, we exclude the observations of financial development variables where the (absolute value of their) annual growth rate is higher than two standard deviations from the mean, where _d(FD)_ is the annual growth rate in our dependent variable, and μ _d(FD)_ and σ _d(FD)_ represent the mean and the standard deviation of _d(FD)_ . Next we evaluate whether the sensitivity of domestic financial development to changes in the extent of international financial integration changes over time. We examine whether the coefficient estimate of financial openness changes during the globalization period between the pre- and post-Asian crisis period (1990-1998 and 1999-2007).

_Sensitivity to large swings in financial markets_ . Table 6 reports the baseline regression results when we exclude large swings in banking activity, stock and bond market development, and depth of other financial institutions. The results reported in this table are compared to those reported in the first three columns of Table 5. The results are robust to the exclusion of the data outliers, and qualitatively similar (with small quantitative differences). In sum, higher financial integration:

- Promotes the activity of the banking system (with elevating private credit provided by deposit money banks or by deposit money banks plus other financial institutions) and of other financial institutions (with raising the premium of life insurance contracts).

- Boosts the total assets of deposit money banks and expands the liquid liabilities of the financial system.

- Improves the efficiency of banking activity by cutting net interest margins.

- Enhances the development of stock markets (with increasing both the capitalization and traded value of national stock exchanges).

_Sensitivity of the financial openness coefficient over time_ . Table 7 reports the IV coefficient estimates of financial openness (either proxied by foreign assets and/or foreign 16
liabilities as % of GDP) and its interactions with dummy variables for the period 1990-1998 and 1999-2007. Our findings are as follows:

- Financial openness enhances private credit by domestic money banks. The impact is higher in the globalization period especially after the Asian crisis. An analogous result holds both for the amount of assets by deposit money banks and for liquid liabilities of the financial system.

- Financial openness has a positive impact on stock market capitalization and total value traded; however, this positive effect declines during the globalization era.

# **4. Extensions**

We further investigate the relationship between domestic financial development and financial openness in two different dimensions. First, we test whether the structure of external assets and liabilities plays a role on the effect of financial openness on financial development. Does the accumulation of risky assets (or liabilities) rather than riskless assets (or liabilities) have a different impact on the activity of financial intermediaries or the depth of stock and bond markets? Then, we test whether the impact of financial openness on the depth of financial markets depends upon the institutional quality, investor protection, and openness to international trade. We also investigate whether these three factors may help explain the differing (if existing) effects of equity- and loan-related financial openness.

## **4.1 Does the Structure of External Assets and Liabilities Matter?**

Our first goal is to examine closely the relationship between domestic financial development and financial openness by evaluating whether the structure of external assets and liabilities tends to play a role in explaining this relationship. Do financial systems tend to intermediate more financial flows whenever the country accumulates riskier assets rather than riskless assets? Calderon and Kubota (2009), in their earlier work, find that the structure of external assets and liabilities play a significant role in identifying forces that either enhanced or mitigated shocks to the real exchange rate. They find that financial openness would attenuate (magnify) real exchange rate volatility, the greater the share of equity (debt) in foreign liabilities. Analogously, this paper investigates the effects of accumulating more riskless assets and/or liabilities (debt, reserves) rather than riskier assets and/or liabilities (direct investment and portfolio equity) on banking sector activity, stock market and bond market development.

17
Table 8 improves upon the results of Table 4 by including equity-related and loanrelated holdings of foreign assets and liabilities instead of total holdings. We show our full regression results for bank credit, bank deposit and stock market capitalization for the full sample. There is a robust positive coefficient for income per capita and trade openness. Higher income per capita and greater international trade linkages would lead to deeper domestic financial markets as captured by rising bank credit and deposits as well as widening stock market capitalization. Higher inflation and the presence of dual or freely falling exchange rates would reduce the depth of financial markets.

What is the impact of equity- and loan-related holdings of assets and liabilities on the development of domestic financial markets? Regardless of the measure of financial openness in most cases that larger holdings of either equity- or loan-related foreign assets and/or liabilities would lead to: (a) more private credit provided by deposit money banks, (b) a greater amount of bank deposits, and (c) deeper stock markets. The accumulation of risky assets leads to higher bank credit and bank deposits whereas the hoarding of riskless assets has a non-significant effect on bank deposits. Moreover, the accumulation of direct investment and portfolio equity liability holdings leads to higher bank credit and deposits whereas accumulation of debt liabilities causes higher bank credits and lowers bank deposits in Table 8.

Table 9 reports the coefficient estimates of equity-related and loan-related financial openness of the financial development regression equation for measures of size, activity and efficiency of financial intermediaries, and measures of stock and bond market development as well as insurance penetration. We report the results for both full sample and sub-samples of industrial and developing countries.

_Activity of financial intermediaries_ . Equity-related financial openness causes higher private credit in the banking system with the exception of equity related foreign liabilities of industrial countries. Although the impact of loan-related financial openness is positive and robust for industrial economies, it is not significant for developing countries. For bank deposits we find that equity-related financial openness leads to higher deposits in the banking system for both full sample and sub-sample of developing countries. Equity-related financial openness has a negative and significant effect on bank deposits although loan-related financial openness leads to higher bank deposits in industrial countries and to a negative and non-robust effect on bank deposits for developing countries in Table 9.

18
_Size of financial intermediaries_ . The accumulation of equity-related foreign assets leads to higher assets of deposit money banks for industrial and developing countries while loanrelated foreign assets raise bank assets in industrial countries and have no significant in developing countries. Loan-related financial openness also has a positive effect on the liquid liabilities of the financial sector for both industrial and developing countries. However, equityrelated financial openness has a negative impact on liquid liabilities in industrial countries and a non-robust effect in developing countries.

_Efficiency of financial intermediaries_ . A negative and significant impact of both equityand loan-related financial openness on net interest margin is found in most cases, with the coefficient of loan-related financial openness being larger (in absolute value) than that of equity-related financial openness. Equity-related financial openness leads to higher overhead costs and banking concentration for the full sample (and this result is consistent with those found for developing countries).

_Stock market development_ . In most cases higher equity-related financial openness leads to rising stock market capitalization and total value traded in industrial and developing countries while loan-related financial openness has no robust relationship with the measures of stock market depth. Note that larger holdings of loan-related assets cause higher stock market capitalization and value traded among industrial and developing countries in Table 9.

_Bond market development and the depth of other financial institutions_ . Rising equityand loan-related financial openness has a robust effect on private market bond development in industrial countries while higher loan-related financial openness leads to lower depth of private bond markets. Rising holdings of equity-related assets and/or liabilities significantly causes higher public market bond capitalization in industrial countries while rising loan-related openness would significantly lower public market bond capitalization for all countries. In developing countries equity- and loan-related financial openness has no systematic effects on public market bond capitalization. Life insurance penetration rises due to higher equity-related financial openness in industrial countries and due to loan-related financial openness in developing countries.

# **4.2 Financial Openness and Financial Depth: the Role of Institutions, Investor Protection and Trade Openness**

We have showed that the impact of financial openness on domestic financial development may depend on whether countries accumulate equity-related or loan-related asset and liability holdings. In this section we examine to what extent the role of the structure of external asset and liabilities is driven by differences across countries in three key structural features of the domestic economy: institutional quality, investor protection, and trade openness.

In order to test whether these structural features play a role in explaining the different effects of equity- and loan-related financial openness on domestic financial development ( _FD_ ), we model the coefficient γit in equation (1) as: where _IQ_ is the level of institutional quality, _IP_ is index of investor protection, and _TO_ is the extent of trade openness. According to the literature reviewed, we expect γ1, γ2 and γ3 to be positive.

Table 10 shows the full regression results of financial market development on our set of control variables, financial openness and its interactions with the three structural features mentioned above. We report the regressions for bank credit, bank deposits and stock market capitalization with different measures of financial openness and for the full sample period. Analogous to the results in Tables 4 and 6, financial markets are deeper in countries with higher income per capita and are shallower in those with higher inflation rates as well as dual or freely falling exchange rates. The impact of trade openness will depend on the level of financial openness.<sup>8</sup> What is the impact of financial openness on domestic financial development? The effect of financial openness depends on the level of institutions (γ1), the degree of investor protection (γ2) and the extent of trade openness (γ3). Our regressions for bank credit and bank deposits show that the coefficient of financial openness (γ0) is negative and significant while the interaction coefficients with institutions, investor protection and trade openness (γ1, γ2 and γ3, respectively) are positive and significant regardless of the measure of financial openness used in

> 8 Given the results depicted in Table 8, trade openness would raise bank credit and bank deposits in countries with high financial integration.

Table 10. These results imply that rising financial openness may lead to higher financial development – _i.e._ higher bank credit and bank deposits– in countries with medium- to highlevels of institutional quality, investor protection and trade openness (see Figures 2 and 3). The coefficient of financial openness (γ0) is not significant in the regression of stock market capitalization and the same holds for almost all interaction coefficients, except for some interactions between financial openness and the degree of the investor protection.<sup>9</sup> Table 11 reports the coefficient estimates of our variable of interest (financial openness) and its interactions with institutional quality, investor protection and trade openness. We report the coefficient estimates for measures of size, activity and efficiency of financial intermediaries, and stock market development, bond market development and the depth of other financial institutions. Similarly, Table 12 reports the coefficient estimates of financial openness and its interactions for developing countries. Due to the limited space we restrict our discussion of the results to the full sample.

Analogous to the results found for bank credit and deposits, we find that the coefficient of financial openness is positive and significant while its interactions are unexpectedly negative and significant for the regressions of deposit bank total assets and liquid liabilities of the financial system. According to Table 11, this implies that rising financial openness may raise the size of financial intermediaries –by increasing bank assets and the liquid liabilities of the financial system– with medium to high levels of institutional quality, investor protection and trade openness (see Figures 4 and 5).

Regarding the impact of financial openness on the efficiency of the banking system we find that: (a) the autonomous and conditional impact of financial openness on overhead costs and banking concentration is not robust across measures of financial openness and across our samples. (b) Using either foreign assets or the sum of foreign assets and liabilities, rising financial openness leads to lower net interest margins in countries with medium to high levels of institutional quality for the full sample, medium to high levels of investor protection for developing countries and high levels of trade openness for both the full sample and developing countries. See Table 11 and Figure 5 for more details on the regression analysis.

Rising financial openness leads to higher stock market development especially when we use the ratio of foreign assets and liabilities to GDP while most of the interactions are not

21
statistically significant. Hence, the level of institutional quality, the degree of investor protection and the extent of international trade integration play no significant role on the impact of financial openness on stock market development.

One strand of the empirical literature argues that an enhanced institutional environment not only deepens local stock markets but also reduces the need to use international markets (Karolyi, 2004). Internationalization of firms in countries with weak institutions becomes more attractive due to the opportunity to participate in a market that offers better protection of investors’ rights (Benoch and Weisbach, 2004). Others show that –on the contrary– financial liberalization may lead not only to deeper stock market capitalization but also to greater internationalization (Claessens et al. 2006, 2007; De La Torre et al. 2007).

Finally, although rising financial openness may lead to higher private bond market capitalization with moderate to high levels of institutions and openness, the opposite holds for public bond market capitalization. The unexpected sign for public bond market capitalization may reflect the risks of opening its the market in a country that has not either achieved macroeconomic stability yet or developed strong and stable currencies among other factors.

_Quantifying the role of institutions, investor protection and trade openness._ Table 13 reports the response of banking credit to a shock in financial openness — _i.e._ 100% increase in our indicator of financial openness— conditional to a structural characteristic (say, institutions) while keeping the other dimensions (say, investor protection and trade openness) constant at their sample median values. We report the conditional response of domestic financial development when one of the structural characteristics is evaluated at high (top quintile or 80<sup>th</sup> percentile) or low (bottom quintile or 20<sup>th</sup> percentile) levels and we test whether the difference in those responses are statistically significant.

How quantitatively significant are the estimates of our financial development responses? Assuming that external assets (as a percentage of GDP) double, we evaluate this rise in financial openness with low and high levels of institutional quality, investor protection and trade openness (20<sup>th</sup> and 80<sup>th</sup> percentiles of the corresponding variables in their sample distribution). Doubling foreign assets leads to a reduction in bank credit of 5.1% with low institutions and to an increase of 7.3% with high institutions. An analogous increase in financial openness causes a decline in bank credit of 5.3% with low levels of investor protection and an increase of 7.4% with high investor protection. The impact of financial openness on bank credit 22
leads to a decline of 1.4% in bank credit for low-trade-openness-countries and a slight increase of 4.6% with high integration to international markets of goods.

In the case of bank deposits higher financial openness (as proxied by a 100% increase in the ratio of foreign assets to GDP) leads to a reduction (an increase) in bank deposits of 9.2% (3%) with low (high) levels of institutional quality. Bank deposits would also decline (rise) by 6.5% (0.7%) with low (high) degrees of investor protection. Doubling foreign assets would generate a reduction (jump) in bank deposits of 5.2% (0.1%) with low (high) degrees of trade openness. Therefore, the structural factor plays a role in explaining the differences in response.

Moreover, we find that a shock that doubles foreign assets to GDP would lead to an increase of approximately 2% in bank assets for the representative country. For countries with poor institutions (percentile 20) there is a decline of 3.4% in bank assets while an increase of 6% is predicted for countries with good institutions. An analogous increase in financial openness would lead to a decline of 0.1% in bank assets with lack of investor protection while it increases by 6.7% with good investor protection. Bank assets in closed economies would also increase by 0.1% in the event of rising foreign assets to GDP whereas bank assets in open economies would increase by 3.4% (see Table 13 for more details).

_Sensitivity analysis for the “expanded” model_ . We test whether the coefficient estimates of our “expanded model” are influenced by episodes of sharp fluctuations in domestic financial markets. We also exclude country-year observations where the annual growth of financial variable is larger (in absolute value) that a determined threshold which in our case is determined by two standard deviations from the regression sample-mean. Then we test the sensitivity of our results to changes in measures of: (a) institutional quality ( _IQ_ ), (b) investor protection ( _IP_ ), and (c) trade openness ( _TO_ ). These regressions are conducted by changing one dimension (say, institutions) and keeping the other ones constant (say, investor protection and trade openness).

Table 14 reports the coefficient estimate of financial openness as well as its interactions with institutional quality, investor protection and trade openness after eliminating large observed variations in domestic banking, equity and bond markets. On average, we lose 3-3.5 percent of the regression sample while eliminating these sharp fluctuations. The results are qualitatively similar to those found in Table 11. The response to doubling foreign assets conditional on median values of _IQ_ , _IP_ and _TO_ is smaller in most of the cases when we restrict the sample. For instance, doubling the ratio of foreign assets to GDP would increase private 23
credit by deposit money banks increases by 1.9% if we use the full sample vs. 1.8% when we eliminate the outliers. The discrepancies are much larger if we examine the effects of an analogous increase in liquid liabilities (4.1% vs. 3.6%) and stock market capitalization (22.7% vs. 20.5%).

Table 15 shows the _sensitivity of our estimates to changes in the measures of institutional quality (IQ)_ . Here we use the different components of this aggregate index such as index of political institutions ( _IQ1_ ), index of the quality of institutions ( _IQ2_ ), index of socioeconomic environment ( _IQ3_ ), and the index of conflict ( _IQ4_ ). We perform this exercise both for foreign assets ( _FA_ ) and foreign liabilities ( _FL_ ) and for a selected set of financial development indicators. _Ceteris paribus_ , we find that the coefficient estimates of the interaction between _FA_ and the components of _IQ_ are positive and significant when estimating the regression for bank credit, bank deposits, bank assets, and liquid liabilities of the financial system. An analogous result holds for the interaction between _FL_ and the components of _IQ_ in the activity and size of financial intermediaries. The results are not as robust for net interest margin, stock market capitalization and value traded. The interaction coefficient between financial openness (either proxied by _FA_ and _FL_ ) and the different measures of _IQ_ is positive and (in most cases) statistically significant. Thus, evidence on the positive impact of financial openness on financial development with strong institutions is robust for the size and activity of banking intermediaries and the depth of private bond markets.

We evaluate the _sensitivity of our results to changes in the measure of investor protection (IP)_ and the results are reported in Table 16. We use the components of the investor protection index from the Doing Business report: disclosure index, director liability index, and shareholder suits index. For the measures of size and activity of bank intermediaries such as bank credit and deposits, assets of deposit money banks, and liquid liabilities, we find that the interaction of the different _IP_ measures and _FO_ (approximated by _FA_ or _FL_ ) has a positive and statistically significant coefficient. Unfortunately, we do not find a robust coefficient estimate for this interaction while evaluating stock and bond market development.

We also perform _sensitivity analysis of the coefficient estimates to different measures of trade openness (TO)_ . Rather than using trade openness we incorporate in the regression analysis trade in manufacturing and in non-manufacturing goods and the interaction of the corresponding measure of financial openness (say, _FA_ or _FL_ ) with manufacturing and nonmanufacturing trade. Table 17 shows the interaction coefficient of financial openness ( _FA_ , _FL_ or 24
_FAL_ ) and trade in manufacturing and non-manufacturing goods. The interaction of _FA_ and trade manufacturing is positive and significant for bank and financial credit as well as bank assets and liquid liabilities. This result implies that higher foreign assets would enhance bank credit and enlarge bank assets with higher trade in manufacturing. This interaction coefficient is not as robust when we run our regressions on stock market and bond market development. However, the interaction between _FA_ and non-manufacturing trade is negative and significant for financial credit, bank assets, liquid liabilities and stock market development. Hence, financial openness does not seem to have an enhancing effect on bank and stock market developments in countries with higher non-manufacturing trade.

# **5. Concluding Remarks**<sup>**10**</sup>

The main goal of our paper is to evaluate the effect of greater international financial integration on the development of domestic financial market institutions such as commercial banks, stock markets, bond markets, and other financial institutions. We gathered annual information for a sample of 145 countries over the period 1974-2007 and tested: (a) whether integration to world capital markets promoted higher levels of activity in banking and nonbanking financial institutions, stock and bond markets, (b) whether the impact of financial openness depends upon the structure of external assets and liabilities held by the country (risky vs. riskless assets and liabilities), and (c) whether the effects of higher integration to international markets of assets depend upon the domestic country’s level of institutions, degree of investor protection and extent of trade openness. We find that: First, higher integration in world capital markets would enhance the development of domestic financial markets by raising bank credit, total assets of the banking system, reducing net interest rate margins, increasing stock market capitalization and total value traded and improving the capitalization of private bond markets.

Second, the structure of external assets and liabilities appears to play a role in explaining the impact of financial openness on domestic financial development. For instance, the accumulation of risky assets (i.e. direct investment and portfolio equity) may lead to an expansion in bank credit and bank deposits while the hoarding of riskless assets (debt and reserve assets) raises bank credit but has no effect on bank deposits.

> 10 We particularly thank Augusto De La Torre for conversations on the short-run tensions of opening financial markets and issues of reform sequencing.

25
Third, the response of domestic financial development to higher international financial integration may depend upon the level of institutional quality, the degree of investor protection and the international trade linkages of the domestic country. In general, we find that banking size and activity will expand in response to an increase in financial openness in countries with moderate to high levels of institutional quality and investor protection and with high trade openness. An analogous result holds for efficiency of commercial banking activities and private bond market development.

Fourth, we should point out that financial globalization may have clear benefits on financial development in the longer term but may create short-run tensions –as pointed out by De La Torre et al. (2007) and Kaminsky and Schmukler (2008). Financial globalization may challenge the efforts to deepen reforms in local stock markets as they may result in rising participation of local firms in international capital markets. This may generate liquidity problems for those firms that remain in local markets –especially, small and medium sized enterprises with limited or no access to world capital markets.

Finally, further avenues of research could be pursued in the following areas: First, we may need to examine whether the liberalization of domestic financial markets leads to higher integration of countries to world capital markets. In this respect, we may need to assess whether the causal relationship from financial openness to domestic financial development dominates the dynamic correlation between these two variables or the other way around. Second, one of the major differences between opening local stock markets vis-à-vis local debt markets is that the quality of the local currency plays a crucial role on the effects of financial globalization on the latter. For instance, having a ‘sound currency’ has allowed emerging market economies (and, especially those in Latin America) to further deepen their local-currency debt markets. This implication may merit further testing. Finally, the sequence of reforms is an important issue at hand. De La Torre et al. (2006) argue that opening financial markets without an adequate institutional and regulatory environment may lead firms and investors to use international markets more intensively in detriment of local financial markets. An analogous behavior may be observed if local debt markets are liberalized before developing a stable local currency and deepening local currency debt markets. Further analysis of the behavior of initial conditions (say, the strength of domestic currency and quality of regulatory framework) around dates of capital account openness may be undertaken.
