Alan Greenspan, Fed Chair Under 4 Presidents, Dies at 100

Alan Greenspan, the economist who served as chairman of the Federal Reserve under four U.S. presidents and shaped American monetary policy for nearly two decades, died Monday, June 22, 2026, at the age of 100. His wife, NBC News correspondent Andrea Mitchell, confirmed that Greenspan died from complications of Parkinson's disease.

Greenspan's tenure at the Federal Reserve from 1987 to 2006 made him one of the most powerful unelected officials in American history. Appointed first by President Ronald Reagan, he was subsequently reappointed by Presidents George H.W. Bush, Bill Clinton, and George W. Bush — a span of influence that crossed party lines and defined an era of American economic life. At the height of his influence in the 1990s, he was spoken of in almost mythological terms. Senator John McCain once joked that if Greenspan died, the country should 'prop him up and put sunglasses on him' rather than disrupt the markets — a line that captured how indispensable Greenspan had become to Wall Street confidence.

Born on March 6, 1926, in New York City, Greenspan trained as a classical musician before turning to economics, eventually earning his Ph.D. from New York University in 1977. He founded a successful consulting firm, Townsend-Greenspan & Co., before entering public service. His appointment as Fed chairman came at a pivotal moment — just two months after he took the job, the stock market crashed on Black Monday in October 1987, dropping 22 percent in a single day. Greenspan's calm, decisive response — flooding the banking system with liquidity — steadied the markets and established his reputation as a crisis manager of extraordinary skill.

The 1990s brought Greenspan's greatest triumph: he presided over the longest peacetime economic expansion in U.S. history, a boom stretching from 1991 to 2001 that created more than 20 million new jobs and produced four consecutive years of federal budget surpluses. He famously coined the phrase 'irrational exuberance' in a 1996 speech warning that stock market valuations had become dangerously disconnected from economic fundamentals — a prescient observation that the dot-com bubble would dramatically confirm four years later.

Yet history's verdict on Greenspan is complicated. His aggressive interest rate cuts following the dot-com bust, combined with his long-held opposition to regulating the mortgage derivatives market, are widely cited as key contributors to the conditions that produced the 2007-2008 global financial crisis — the worst economic catastrophe since the Great Depression. In a rare moment of public accountability, Greenspan testified before Congress in October 2008 that he had found 'a flaw' in his ideology. 'I was shocked,' he told lawmakers.

Reactions to Greenspan's death poured in Monday from across the political and financial spectrum. Former Treasury Secretary Janet Yellen called him 'a towering figure in the history of American economic policy.' Former Fed Chair Ben Bernanke said: 'Alan dedicated his life to public service and to understanding the forces that drive economic prosperity. His legacy is vast and complex, and economists will be debating it for generations.'

Greenspan is survived by his wife Andrea Mitchell, whom he married in 1997. He leaves behind a complicated but undeniably consequential legacy — the architect of America's greatest peacetime boom, and a man whose later years were marked by sober reckoning with the limits of his own certainties. He was 100 years old.
