Dominant academic paradigm may restrict those who radically incorporate lessons of these days into their studies. And of course, central banks, as always, will be criticized for spoiling the party at its hottest moment by taking away the punch bowl. We should be aware that keeping the old habits will only give us a new and may be more severe crisis in the near future. Thanks to the global efforts, lessons derived from the crisis have already started to initiate dramatic changes in the global financial governance. There have been encouraging developments in recent months to design a new global financial system to prevent future crises. In the recent meeting of G-20 finance ministers and central bank governors, member  BIS Review 120/2009  1  countries confirmed their commitments to the principles of strengthening transparency and accountability, enhancing sound regulation, promoting integrity in financial markets, and reinforcing international cooperation. I believe the establishment of Financial Stability Board with increased participation of emerging countries is a critical step in achieving these objectives. In recent years, as a byproduct of market-oriented structural reforms and prudent macroeconomic policies, the share of emerging countries in world output and their role in global financial markets has significantly increased. Now, we are faced with a more diversified group of countries with different objectives and interests. Since the rise of emerging economies has dispersed economic power, decision-making process and international cooperation has become more complicated.
However, risks only changed form and address in the financial system, just like the energy continuously transforms in the physical universe. Almost all economists agree that we are heading to a slow, gradual and painful recovery. And as a central banker who has spent almost 30 years in this profession, I can tell you that it is a miracle itself to have so many economists agree on one issue with so much vigor and conviction. The future of the global financial system will be shaped by the lessons we derive from our current experience. The ongoing crisis revealed that preventive measures put in place at the local level by national authorities may not be effective to address global problems. It also underlined the importance of international cooperation and coordination in designing and implementing economic policies. It is clearly understood that the only way to prevent future crises at the global scale is multilateral cooperation. However to establish and sustain multilateral cooperation is not an easy task. As (John Maynard) Keynes once said, “The biggest problem is not to let people accept new ideas, but to let them forget the old ones.“ It is very likely that economic agents will try to hold onto their old habits when the effects of the crisis subdue. Appeals on regulators will pile up for a more lenient implementation of rules, regulations, and policies. Politicians will face pressure from their constituents to give priority to local concerns at the expense of global coordination.
