Vitas Vasiliauskas: Macroprudential regulation and financial
stability
Speech by Mr Vitas Vasiliauskas, Chairman of the Board of the Bank of Lithuania, at the
HighLevel International Forum, Minsk, 1 November 2019.

Dear Governor Kallaur, Ladies and Gentlemen,
It is my great pleasure to join you at this High-Level International Forum - and to celebrate the
25th Anniversary of the Belarusian Ruble. Congratulations on this important milestone.
Financial stability is key to ensuring trust in any currency. Therefore, the topic I was invited to
discuss today - namely, macroprudential regulation - fits the occasion well.
In my remarks, I will consider three dimensions to macroprudential policy-making: the
international, the European, and the domestic, or national, level.
Let's begin with a broader international perspective.
The global financial crisis taught us a lesson: microprudential regulation and supervision alone
are not enough to safeguard the financial system. Vulnerabilities may build up across the
financial sector through complex interlinkages - even though individual entities may seem stable
on a standalone basis.
The crisis was thus a catalyst for the rise of macroprudential policies. The focus turned to
ensuring the stability of the financial system as a whole. International cross-cutting post-crisis
reforms - such as Basel III - helped accelerate this process.
Today, over 90% of world economies have at least one macroprudential policy measure in place.

The average number of measures per country is more than nine .
In other words, macroprudential policy has become mainstream. A saying was even born,
2
paraphrasing Milton Friedman, that "we are all macroprudentialists now" .
Of course, the macroprudential domain differs across regions.
In emerging market countries, tools to manage foreign exchange mismatches in the banking
system are more popular than in advanced economies. Such measures include, for example,
3
limits on the net foreign exchange position. Many countries also differentiate liquidity tools and
reserve requirements by currency. By minimising foreign exchange lending risks and
encouraging local currency savings, these instruments can directly strengthen the role of local
currencies.
Across the advanced economies, bank capital measures are the top choice. And, in recent
years, more countries are activating borrower-based instruments, such as restrictions on
loanto-value and debt-to-income or debt-service-to-income ratios. The usage of such measures is
related to high levels of mortgage lending, and the overall experience with housing sector
vulnerabilities in these economies.
These are some of the examples of the growing number of macroprudential measures used
across the world. Have they been effective in ensuring financial stability?
Let us not be too optimistic: financial crises have always happened and will always happen.
However, macroprudential policy can surely mitigate the most harmful manifestations of the
financial cycle - especially in the current low interest rate environment that encourages
excessive risk-taking.
Surely, more research is needed on the topic. But the evidence is mounting, particularly in terms
of loan-targeted instruments. For instance, many papers, including IMF research, have found that
loan-to-value and, especially, debt-service-to-income limits can reduce household credit growth
and house prices.
Dear Colleagues,
Prior to the global financial crisis, only a few countries in the EU made use of macroprudential
measures, and there was a great deal of uncertainty over which instruments to choose - and
how to calibrate them.
But that has changed. I would therefore like to quickly zoom in on the European dimension.
During the post-crisis period, macroprudential authorities came into existence in almost all EU
4
Member States , and the policy toolkit was built up. Important Basel III measures - such as the
countercyclical capital buffer and the buffer for systemically important institutions - were
5
transposed into EU law .
Today, all EU Member States have set and regularly review the buffers for their domestically and
globally systemically important institutions, while a positive countercyclical capital buffer rate has
been active or announced in 12 of the Member States.
Borrower-based measures have not been fully harmonised at the EU level. Nevertheless, they
have already been implemented in 17 Member States to curtail credit growth and household
leverage.
Harmonised or not, macroprudential measures have been implemented in a relatively consistent
manner across Europe. This is due, in part, to the comprehensive governance structure that was
set up after the crisis. This structure features a two-tier system. Countries are first in line to
counter systemic risk. In the euro area, the ECB is responsible for assessing measures adopted
by national authorities - and applying higher requirements if deemed necessary. The European
Systemic Risk Board brings together all the relevant institutions to carry out oversight, and
issues recommendations or warnings - for all EU Member States and EU institutions.
Dear colleagues,
We have talked about international and European perspectives. But final decisions on
macroprudential policy are taken at the national level. This is where instruments are calibrated
and adopted to country-specific circumstances. Macroprudential policy-making is still a rather
novel exercise: one can say that every country engages in a sort of experiment to find the right
medicine.
In Lithuania, the central bank became the macroprudential authority in 2014. Indeed, it is a very
important mandate. Lithuania does not have domestically orientated monetary policy as we have
been part of the Eurosystem since 2015. For that reason, proactive use of macroprudential
measures has become the main roadblock against the build-up of cyclical systemic risks in the
country's financial system.
Unfortunately, we did not have such safeguards 10 years ago, when we were hit particularly hard
by the boom-and-bust cycle. House prices dropped sharply - by 30% in 2009, which was the
second-worst drop in the whole EU.
I think this taught us a lesson. In the post-crisis years, Lithuania has been eager to find an
effective combination of macroprudential policy measures. In 2011, we were among the first in
the EU to establish restrictions on loan-to-value, debt-service-to-income, and loan maturity.
I have to say that, in introducing those measures in 2011, we did so without having a clear legal
mandate. We introduced them by using secondary legislation, based on general provisions under
the law governing the functioning of the Bank of Lithuania. As I mentioned, we only received a
clear legal mandate for implementing macroprudential policy three years later. From a legal point
of view, the step we took in 2011 was a risky one, but nobody challenged it - perhaps due to the
still-recent memories of the 2008-2009 crisis.
Going further, in 2015, to promote responsible lending in a low interest rate environment, we
introduced a limit on debt-service-to-income, while also introducing an interest rate shock
element. At the same time, loan maturity limit was reduced.
Taken together, this is one of the largest sets of borrower-based measures in the EU. It has
created a reliable backstop against the deterioration of lending standards. Combining different
instruments helps prevent evasion, targets a wider range of risk sources, and allows measures
to reinforce each other.
We have also been active in strengthening banks' capital. Macroprudential capital buffers were
introduced as soon as they became available in the European regulation and thus domestic law
- starting from 2015. To prepare against potential shocks in the future, the countercyclical capital
buffer rate in Lithuania has been raised twice, and now stands at 1%. We see this buffer as a
reserve, which could be loosened in bad times to encourage bank lending to the real economy.
Today, the Lithuanian economy is still expanding above its potential - according to our
estimations, it will grow by 3.7% this year. Despite this, we do not see signs of irresponsible
behaviour on the part of creditors or borrowers.
Much of this can be attributed to sound macroprudential policy. For instance, our assessment
reveals that had we not introduced borrower-based measures, house prices would be at least
around 7% higher today, and loan stock to households would be around 10% larger.
I am glad that macroprudential policy is also on the agenda of the National Bank of the Republic
of Belarus. You have in place the main capital buffers in line with Basel standards, as well as the
key borrower-based measures.
Here I must stress that macroprudential policy is not only about measures, but also about the
overall framework. In order to achieve financial stability, clear powers and responsibilities should
be defined. These are the steps that the National Bank of the Republic of Belarus is taking.
In terms of the framework, institutional independence is also key. The task for macroprudential
authorities is to "take away the punch bowl as the party gets going." Those in the party may
prefer it to continue. Authorities should thus be autonomous from outside pressures to be able to
ensure an effective implementation of the mandate.
In Belarus, some of the important work on the macroprudential framework was done during an
EU Twinning project dedicated to enhancing the potential of the National Bank of the Republic of
Belarus. The Bank of Lithuania had the opportunity to participate in the project and took a leading
role in the Financial Stability component.
For us, it was a great experience. I would like to thank the experts and the Board of the National
Bank for their outstanding dedication. It has laid a sound foundation for further development of an
effective macroprudential policy framework in Belarus.
Ladies and gentlemen,
To conclude, macroprudential policy is - so to say - approaching its adolescence, and countries
will continue to fine-tune their frameworks and instruments. However, experience with applying
these tools is growing.
I am confident that through knowledge-sharing and international cooperation, macroprudential
policy will play an increasingly important role in safeguarding financial stability - in all parts of the
world.
