- Today's market turbulence and global imbalances prompt the question whether economic and regulatory policies are poorly designed or just badly implemented. The question is urgent for Europe, which has its own asset booms and imbalances to worry about as well as the backwash of US problems.
- The imbalances in Europe's economies in large part reflect favourable shocks, such as falling interest rates and growing financial integration. But the 'growth crisis' in Portugal underscores the fact that there can be hard landings, even without a financial crisis, if fiscal policy is unwise and if productivity fails to take off.
- The current global imbalances and turbulence also have a common backdrop in the long period of unusually easy liquidity and low risk premia during which today's problems built up. This suggests that central banks should be prepared more often to 'lean against the wind' in times of asset price exuberance, and that politicians should not cut taxes or boost spending permanently on the back of revenue gains that result from transient financial booms.
- Banks and supervisors have many lessons to draw. Some involve going 'back to basics' on issues such as liquidity, off-balance-sheet operations, and the ability to close and reopen banks. Others require a careful look at incentives - in executive pay, rating agency roles and loan production systems. Supervisors also need to take better account of boom-bust cycles when they assess risks, and address cross-border issues in EU banking.
- Moral hazard has been partly addressed by pain inflicted on bank managements and shareholders. But at the macro level it may be building up as policy-makers act to limit losses in a setting where they cannot trace the ultimate fallout from risks. In future, their discretionary interventions need to be truly exceptional and much more symmetrical, or the money supply and the public debt will ratchet up amid serious resource misallocation.
