Can We Regulate Systemic Risk?

MILAN – In the past two years, two dangerous episodes of financial instability and sudden changes in market dynamics have hit the world economy. More are likely, because the global economy is out of balance in several respects as it emerges from the crisis, particularly in terms of sovereign debt and the structure of global demand.

Systemic risks drive most crises, and pose a challenge for several reasons. First, they are not easy to detect with confidence, and are even more difficult to prove. Second, predicting the exact timing of a break point (when bubbles burst, markets lock up, and credit freezes) is, and will likely remain, beyond our ability. Finally, crises are highly non-linear events, which means that they occur without much warning.
