Greenspan Dead at 100: His 18.5-Year Fed Reign Saw a 10-Year Boom, Then Historic Bust

Finance and Markets readers need to understand why Greenspan’s passing matters now. His 18.5-year stewardship of the Federal Reserve not only engineered the longest peacetime expansion in U.S. history but also entrenched a risk-taking culture underpinned by the ‘Greenspan put’ – the belief that the central bank would always bail out markets. As current Fed policymakers grapple with stubborn inflation and asset bubbles, revisiting Greenspan’s record offers a crucial lens on the dilemmas of monetary policy, from interest rate paths to regulatory posture.

Alan Greenspan, the second-longest-serving chairman of the Federal Reserve, died on Monday, June 22, 2026, at the age of 100. His death from complications of Parkinson’s disease, announced by his wife Andrea Mitchell, marks the end of an era that defined modern central banking. Greenspan’s 18.5-year tenure from August 1987 to January 2006 spanned four presidencies and witnessed the transformation of the U.S. economy from the inflation-ridden 1980s to the dawn of the 21st century. He was initially hailed as the ‘Maestro’ who engineered the ‘Great Moderation’ – a period of low inflation and steady growth that fostered a 10-year economic expansion beginning in March 1991 and a historic surge in stock prices. His cryptic, carefully parsed public statements gave rise to an entire industry of Fed-watching, exemplified by folklore like the ‘Briefcase Indicator,’ which traders scrutinized for clues about upcoming rate decisions.

Yet Greenspan’s legacy is deeply bifurcated. Almost as soon as he left the Fed in 2006, the U.S. housing bubble burst, triggering the 2007–2009 Great Recession – the worst downturn since the 1930s. Critics argued that the low-interest-rate environment he maintained after the dot-com crash, combined with his philosophical resistance to financial regulation, inflated a massive credit bubble. His 1996 warning of ‘irrational exuberance’ in stock markets proved prescient, but many economists contend he failed to act on it, instead championing the very financial innovation that later unraveled. In a 2008 congressional hearing, Greenspan conceded a ‘flaw’ in his free-market ideology, a moment that symbolized the humbling of a once-revered oracle.

The Federal Reserve’s own statement on his death emphasized his role in cementing public trust and achieving ‘a sustained era of price stability that supported economic growth.’ This official framing highlights the institutional challenge of memorializing a figure whose career embodies both the triumphs and perils of central banking. For today’s policymakers, Greenspan’s approach – rooted in discretion, opaque communication, and a deep belief in market self-correction – stands in stark contrast to the data-driven, transparent, and often preemptive methods practiced under successors Ben Bernanke, Janet Yellen, and Jerome Powell. The lessons of his tenure continue to inform debates on the Fed’s dual mandate, the risks of asset bubbles, and the delicate balance between inflation control and financial stability.
