Options for managing a systemic bank crisis

The on-going financial crisis results not from a cyclical or managerial failure, but from a structural one: more than 96 other major banking crises occurred over the past 20 years, and these crashes have happened under very different regulatory systems and at different stages of economic development. So far, conventional solutions are being applied—nationalization of the problem assets (as in the original Paulson bailout) or nationalization of the banks (as in Europe). These solutions only deal with the symptoms and not the systemic cause of today’s banking crisis. Similarly, the financial re-regulation that will be on everybody’s political agenda will, at best, reduce the frequency of such crises, but not avoid their re-occurrence. Better solutions are urgently needed because the last breakdown of this magnitude, the Great Depression of the 1930s, ended up in a wave of fascism and World War II. In this paper, we describe a recent conceptual breakthrough—based on the functioning of balanced ecosystems — that shows that all complex systems, including our monetary and financial ones, become structurally unstable whenever efficiency is overemphasized at the expense of diversity, interconnectivity and the crucial resilience they provide. The point is not that ecosystems are a useful metaphor for economies. Rather, both economies and ecosystem
