Recent research shows that capital requirements are only loosely related to a market measure of bank portfolio risk. Changes introduced under Basel II meant that banks with the riskiest portfolios were particularly likely to hold insufficient capital. Banks that relied on government support during the crisis appeared to be well-capitalised beforehand, suggesting they engaged in capital arbitrage. Until the regulatory concept of risk better reflects actual risk, the proposed increases in risk-weighted capital requirements under Basel III will have little effect.

Bank competition policy seeks to balance efficiency with incentives to take risk. This calls for an intermediate degree of competition. This column argues that although the traditional policy tools are rules on entry/exit and the consolidation of banks, the Crisis showed that a focus on market structure alone is misplaced. There are other, newer ways in which competition policy can support financial stability: dealing with too-big-to fail and other structural issues in banking, as well as facilitating crisis management.

Rejigging financial regulation is in vogue. But, in the world of international finance, how well do different regulatory systems join up? This column argues that the US Dodd Frank Act and Basel III are, in part, incompatible and that harmonising them may lead to unintended consequences. The US ought to tread carefully here but should also try hard to maintain the spirit of better financial regulation.

How should financial regulators address problems stemming from liquidity risk? This column argues that the liquidity coverage and net funding ratios proposed for Basel III are economically and politically impractical. It recommends using those ratios as long-term targets while imposing ‘prudential risk surcharges’ on deviations from the targets.

The role of financial institutions in the global crisis has led to a consensus that financial regulation must change. This column argues that the banking lobby, far from depleted, has struck back with a vengeance. It has managed to postpone the much needed regulation for a time when the need for it will be forgotten.
