Mervyn King on Too Big To Fail

Mervyn King, Governor of the Bank of England, recently gave a speech in Edinburgh on the state of the financial sector.

Mr. King gives some spot on analysis of how we got ourselves into this mess, and offers some recommendations for we can get out of it:

Why were banks willing to take risks that proved so damaging both to themselves and the rest of the economy? One of the key reasons –mentioned by market participants in conversations before the crisis hit – is that the incentives to manage risk and to increase leverage were distorted by the implicit support or guarantee provided by government to creditors of banks that were seen as “too important to fail”. Such banks could raise funding more cheaply and expand faster than other institutions. They had less incentive than others to guard against tail risk. Banks and their creditors knew that if they were sufficiently important to the economy or the rest of the financial system, and things went wrong, the government would always stand behind them. And they were right.

....It is hard to see how the existence of institutions that are “too important to fail” is consistent with their being in the private sector. Encouraging banks to take risks that result in large dividend and remuneration payouts when things go well, and losses for taxpayers when they don’t, distorts the allocation of resources and management of risk.

That is what economists mean by “moral hazard”. The massive support extended to the banking sector around the world, while necessary to avert economic disaster, has created possibly the biggest moral hazard in history. The “too important to fail” problem is too important to ignore.

....Separation of activities does not resolve all misaligned incentives. Where private sector entities outside of the utility banking sector engage in a high degree of maturity transformation on a scale that could have consequences for the rest of the economy, the government would not want to stand aside when such an entity fails. That is the heart of the matter. Maturity transformation reduces the cost of finance to a wide range of risky activities, at least some of which are beneficial, but the implicit government guarantee means that the true cost of that maturity mismatch does not, as it should, fall on those who receive the benefits. The aim of policy should be to minimise or eliminate that subsidy. Separation of activities helps not hinders that objective, not least because it is the mixture of activities that reduces the robustness of the system. Although there are no simple answers, it is in our collective interest to reduce the dependence of so many households and businesses on so few institutions that engage in so many risky activities. The case for a serious review of how the banking industry is structured and regulated is strong.
