Too Big to Fail: Not Easily Resolved
As Fed Chairman Ben Bernanke has indicated, too-big-to-fail (TBTF) remains a major issue that is not solved, but “there’s a lot of work in train.” In particular, he pointed to efforts to institute Basel III capital standards and the orderly liquidation authority in Dodd-Frank. The capital standards seek to lower the probability of insolvency in times of financial stress, while the liquidation authority attempts to create a credible mechanism to wind down large institutions if necessary. The Atlanta Fed’s flagship Financial Markets Conference (FMC) recently addressed various issues related to both of these regulatory efforts.
The Basel capital standards are a series of international agreements on capital requirements reached by the Basel Committee on Banking Supervision. These requirements are referred to as “risk-weighted” because they tie the required amount of bank capital to an estimate of the overall riskiness of each bank’s portfolio. Put simply, riskier banks need to hold more capital under this system.
The first iteration of the Basel requirements, known as Basel I, required only 30 pages of regulation. But over time, banks adjusted their portfolios in response to the relatively simple risk measures in Basel I, and these measures became insufficient to characterize bank risk. The Basel Committee then shifted to a more complex system called Basel II, which allows the most sophisticated banks to estimate their own internal risk models subject to supervisory approval and use these models to calculate their required capital. After the financial crisis, supervisors concluded that Basel II did not require enough capital for certain types of transactions and agreed that a revised version called Basel III should be implemented.
At the FMC, Andrew Haldane from the Bank of England gave a fascinating recap of the Basel capital standards as a part of a broader discussion on the merits of complex regulation. His calculations show that the Basel accords have become vastly more complex, with the number of risk weights applied to bank positions increasing from only five in the Basel I standards to more than 200,000 in the current Basel III standards.
Haldane argued that this increase in complexity and reliance on banks’ internal risk models has unfortunately not resulted in a fair or credible system of capital regulation. He pointed to supervisory studies revealing wide disparities across banks in their estimated capital requirements for a hypothetical common portfolio. Further, Haldane pointed to a survey of investors by Barclays Capital in 2012 showing, not surprisingly, that investors do not put a great deal of trust in the Basel weightings....MORE
