of these, the ecb - cfs research network on " capital markets and financial integration in europe " has the closest ties to the theme of this year's conference – the transformation of the european financial system. some of you may have attended the initial workshop here in frankfurt last april. it's a european initiative ; future workshops are to be held at the bank of finland in helsinki, in march next year, and at the bank of greece next november. also related to the present theme is the eurosystem monetary transmission mechanism network. why have we chosen the transformation of the european financial system as our subject on this occasion? the establishment of economic and monetary union ( emu ), almost four years ago, and the introduction of the euro banknotes and coins were real milestones. in respect of the maastricht treaty, they appear to mark the completion of the process of monetary integration in europe. but we shouldn't regard monetary union as an end in itself. the introduction of the euro will have – and already has had – a powerful influence on the development of financial markets in europe and their integration, as we will learn and discuss today. the implications of these developments are manifold and profound, in particular for central bankers, but also for other policy - makers. let me mention a few examples. first and foremost, the transformation of the financial system has an impact on the conduct of monetary policy. for example, the emergence of new financial instruments and changes in the use of existing ones affect the choice, behaviour and interpretation of forward - looking financial indicators of underlying economic variables, such as consumer price inflation and gdp growth. moreover, the implications for the transmission mechanism of monetary policy are of supreme importance to the ecb. but i'll say no more on this matter now, as my colleague otmar issing will cover it in greater depth in his dinner speech this evening. second, financial system transformation affects the implementation of monetary policy. i will give you an example. our weekly main refinancing operations with money market counterparties are conducted on the basis of repurchase agreements ( " repos " ). this requires a list of eligible collateral for such operations. in a changing financial environment, a central bank has to ensure that eligible collateral allows market participants to have efficient and equal access to central bank liquidity. my third example of the importance of financial system transformation to central banks relates to the payment systems function. most central banks in industrialised countries run a

large - value payment system and are involved in the oversight of other payment and securities settlement systems. for reasons of efficient liquidity management by private banks, the eurosystem's target system allows for intra - day overdrafts that are fully collateralised. for target to perform efficiently, it is therefore very important that securities settlement systems are interlinked or consolidated in a way which allows a smooth flow of collateral across the euro area. fourth, past experience has shown that structural change in financial systems may have an impact on financial stability. hence, the structure and modus operandi of the authorities responsible for supervising financial markets and institutions must be designed to prevent any instability from arising. this is, as you are aware, quite a topical issue in the european union. central banks have a genuine interest in this issue, which clearly has its origins in the treaty on european union. the treaty states that the european system of central banks ( escb ) shall " contribute to the smooth conduct of policies pursued by the competent authorities relating to the prudential supervision of credit institutions and the stability of the financial system ". these and related issues will be considered in tomorrow's policy panel discussion, which will start off on the basis of a paper contributed by my colleague tommaso padoa - schioppa. structural change in the financial system is important not only to central bankers but to other policy - makers as well. for instance, all policy - makers should have a clear interest in a further integration of european financial markets. the economic literature tells us that an integration of financial markets is very likely to contribute to economic growth by making the allocation of capital more efficient. the paper by jean - pierre danthine in our third session tomorrow will address this issue. this is why the freedom of capital flows is one of the " four freedoms " at the heart of the europe's single market. indeed, increasing financial integration has always been a major item on the european political agenda. in this context, also the establishment of economic and monetary union should be regarded as giving an important impetus to european financial integration. as things stand now, it is clear that full integration of european financial markets, to the extent possible of course, has not been achieved yet, despite the introduction of the euro. although in some areas, such as the unsecured money market or the bond market, the euro seems to have boosted market integration, in other areas, such as repo and equity markets, the impact
