Black Swans and Financial Stability: A Framework for Building Resilience

This article refines the concept of black swans, typically described as highly unlikely and catastrophic events, to be internally consistent. It explores features of the financial system that prevent the eradication of black swans. The main implication is the need to enhance the financial system’s resilience to withstand unforeseen events rather than focus on past crises. The article introduces a “resilience principle” for designing official-sector policies that can achieve such goals. The principle calls for policies that are adaptable, universal, and systemic. The article provides examples of policies with these features, assuming that the official sector is not better positioned than the private sector to anticipate the unknown.
