PRESIDENT OBAMA 10 days ago set out one important element in the needed structural reform of the financial system. No one can reasonably contest the need for such reform, in the United States and in other countries as well. We have after all a system that broke down in the most serious crisis in 75 years. The cost has been enormous in terms of unemployment and lost production. The repercussions have been international.
Aggressive action by governments and central banks — really unprecedented in both magnitude and scope — has been necessary to revive and maintain market functions. Some of that support has continued to this day. Here in the United States as elsewhere, some of the largest and proudest financial institutions — including both investment and commercial banks — have been rescued or merged with the help of massive official funds. Those actions were taken out of well-justified concern that their outright failure would irreparably impair market functioning and further damage the real economy already in recession.
Now the economy is recovering, if at a still modest pace. Funds are flowing more readily in financial markets, but still far from normally. Discussion is underway here and abroad about specific reforms, many of which have been set out by the United States administration: appropriate capital and liquidity requirements for banks; better official supervision on the one hand and on the other improved risk management and board oversight for private institutions; a review of accounting approaches toward financial institutions; and others.
As President Obama has emphasized, some central structural issues have not yet been satisfactorily addressed.
A large concern is the residue of moral hazard from the extensive and successful efforts of central banks and governments to rescue large failing and potentially failing financial institutions. The long-established “safety net” undergirding the stability of commercial banks — deposit insurance and lender of last resort facilities — has been both reinforced and extended in a series of ad hoc decisions to support investment banks, mortgage providers and the world’s largest insurance company. In the process, managements, creditors and to some extent stockholders of these non-banks have been protected.
The phrase “too big to fail” has entered into our everyday vocabulary. It carries the implication that really large, complex and highly interconnected financial institutions can count on public support at critical times. The sense of public outrage over seemingly unfair treatment is palpable. Beyond the emotion, the result is to provide those institutions with a competitive advantage in their financing, in their size and in their ability to take and absorb risks.
As things stand, the consequence will be to enhance incentives to risk-taking and leverage, with the implication of an even more fragile financial system. We need to find more effective fail-safe arrangements.
In approaching that challenge, we need to recognize that the basic operations of commercial banks are integral to a well-functioning private financial system. It is those institutions, after all, that manage and protect the basic payments systems upon which we all depend. More broadly, they provide the essential intermediating function of matching the need for safe and readily available depositories for liquid funds with the need for reliable sources of credit for businesses, individuals and governments.
Combining those essential functions unavoidably entails risk, sometimes substantial risk. That is why Adam Smith more than 200 years ago advocated keeping banks small. Then an individual failure would not be so destructive for the economy. That approach does not really seem feasible in today’s world, not given the size of businesses, the substantial investment required in technology and the national and international reach required.
Instead, governments have long provided commercial banks with the public “safety net.” The implied moral hazard has been balanced by close regulation and supervision. Improved capital requirements and leverage restrictions are now also under consideration in international forums as a key element of reform.
