Már Guðmundsson: Capital flows and fragmentation of the international financial system Speech by Mr Már Guðmundsson, Governor of the Central Bank of Iceland, in Session I in the conference “Fragmentation in the international financial system – can the global economy become one again?”, organised by the Central Bank of the Republic of Turkey and the Reinventing Bretton Woods Committee, Cappadocia, Turkey, 14 July 2012. *  *  *  For the most part, I will discuss some flaws in the international monetary and financial system(s) (IMFS) and in the European Union (EU) framework for cross-border banking and financial stability as they relate to both net capital flows and vulnerabilities in gross capital positions. My perspective on these issues is that of a policy-maker from a very small, open, and what used to be financially integrated economy, but it is also informed by the work I was involved in during my tenure at the Bank for International Settlements. The current international and monetary and financial system is in some sense a non-system, a hybrid of miscellaneous exchange rate regimes and diverse rules on cross-border capital flows and activities of financial institutions. This opens the door to country choices that, in the aggregate, cause and perpetuate global current account imbalances. This problem and its solution have been discussed extensively, and I will not dwell on that topic here.
Instead, I want to pose this question: Supposing that all countries had free capital movements, freely floating exchange rates, and first-rate macroeconomic policies aimed at internal balance, would everything then be fine, at both the national and global level? I think there are strong indications that it would not be. There are a few reasons for this. First of them is the tendency of exchange rates to move away from equilibrium values for extended periods, with sharp corrections at the end of the process and with excess volatility throughout. The research on this phenomenon is still ongoing, but there are strong indications a number of factors suggest that the process is related at least partly to how asset markets function and how expectations are formed, and would not disappear even if macroeconomic policies were perfect. There will be net capital flows associated with this process, as well as swings in current accounts and effects on domestic financial systems that can ultimately lead to serious financial instability. In a small, open, and increasingly financially integrated economy, the process runs as follows: Domestic interest rates at the longer end of the maturity spectrum tend to become more closely correlated with the global rate, or the rate of the largest trading partner, and less correlated with the domestic policy rate. This means that monetary transmission tends to go increasingly through the exchange rate channel, which is only a problem, however, if the exchange rate behaves badly. Unfortunately, there is copious evidence to suggest that it is a problem.
