Bank capital requirements should be abolished, new research suggests

Swathes of complex capital regulation have made banking riskier

State regulation of bank capital has encouraged banks to game the system and contributed to the problems of the financial crash of 2008. In this new paper, Do we need regulation of bank capital? Some evidence from the UK, it is shown that banks held appropriate amounts of capital before the introduction of capital regulation through the Basel system.

Capital regulation for banks is relatively recent. History demonstrates that capital regulation is not necessary if banks are not underwritten by the state. During the early-mid nineteenth century, there were a number of banking crises. Banks responded by holding higher levels of capital.

An analysis of bank capital shows that banks adjusted their capital ratios according to the risks that they were taking and that they were well capitalised in comparison with the standards set by regulators under the Basel I and Basel II approaches in later years.

Indeed, when bank capital levels became very thin after the Second World War, banks were prevented by the Bank of England from raising more capital, despite their appeals to the Bank. It was the banks themselves that wanted higher capital levels and the regulator that refused.

During this long period of prudent management of the banking sector, there was no clear expectation that the state would have stepped in to save an insolvent bank in Britain.

If banks know that they will bear the costs of failure, a century of evidence suggests that they will behave in a conservative manner. Therefore, the focus of bank regulation should be on ensuring the orderly failure of banks. Banks would then be more sensitive to risk and have more of an incentive to adjust their capital ratios to an appropriate level. Regulatory capital ratios lead to more complexity and the gaming of the system.

Recommendation: The whole apparatus of bank capital regulation which has done so much to make the banking system mo
