A Minsky Moment is a sudden and sharp financial collapse that follows a prolonged period of speculative borrowing and risk-taking. The term was coined in reference to economist Hyman Minsky, who argued that financial systems become increasingly unstable during times of economic calm, as investors and institutions take on excessive leverage under the illusion of safety.
Named by economist Paul McCulley, a Minsky Moment occurs when borrowers can no longer service their debt, triggering widespread defaults, asset sell-offs, and panic. It typically marks the point where debt-fueled expansion tips into crisis, revealing the fragility built up during the preceding boom. Minsky’s central idea—that “stability breeds instability”—captures the paradox at the heart of many financial meltdowns.
