Financial Instability Hypothesis
Minsky's foundational claim that capitalist economies endogenously generate the conditions for their own crises — stability breeds instability through the rational behavior of participants responding sensibly to calm.
The Financial Instability Hypothesis is Hyman Minsky's central theoretical contribution, developed across four decades of writing and largely ignored until the 2008 global financial crisis made it impossible to dismiss. The hypothesis holds that capitalist economies with sophisticated financial institutions are inherently unstable, and that the instability is produced endogenously — from inside the system, through the normal operation of profit-seeking — rather than imported from outside by wars, policy errors, or natural disasters. The mechanism is specific: during periods of stability, rational actors progressively reduce their margins of safety because the margins appear unnecessary; the progressive reduction accumulates systemic fragility that is invisible during the calm and revealed only by disturbance. The hypothesis inverts the textbook assumption that crises are aberrations from equilibrium. For Minsky, the crisis is what equilibrium produces.

The hypothesis emerged from Minsky's dissatisfaction with the neoclassical synthesis that dominated postwar economics, which treated financial crises as exogenous shocks to otherwise stable
