Alan Greenspan, the former chairman of the U.S. Federal Reserve whose long tenure made him one of the most closely watched economic policymakers in the world, died Monday at 100 from complications of Parkinson’s disease, his wife, NBC News correspondent Andrea Mitchell, said. Greenspan led the Fed from August 1987 to January 2006, serving through administrations of both parties and becoming a defining figure in American economic policy. The Federal Reserve said his leadership helped deliver price stability, support economic growth and strengthen public confidence in the institution.
During his 18 1/2 years at the central bank, Greenspan oversaw a period marked by a long economic expansion, subdued inflation and surging stock prices. He won early acclaim after helping steady markets following the October 1987 crash, when the Dow Jones Industrial Average fell 22.6% in a single day. He was later credited with guiding the economy through additional periods of stress, including the Asian financial crisis in the late 1990s. Supporters cast him as a central architect of the modern U.S. economy, and by the end of his tenure he had acquired near-mythic status in financial circles as the “Maestro” and the “Oracle,” with investors parsing even his most opaque public remarks for signals about interest rates and growth.
That standing was sharply reassessed after his departure from office. The collapse of the U.S. housing market and the global financial crisis that followed prompted critics to argue that Greenspan’s low-interest-rate policies and confidence in lightly regulated markets helped lay the groundwork for the Great Recession of 2007-2009. Some critics also faulted his opposition to tighter oversight of derivatives and his broader belief that financial institutions could largely regulate themselves. Greenspan later acknowledged a mistake in assuming banks would act in ways that protected the broader system, and in congressional testimony said he had found a flaw in his free-market view of self-regulation. He continued, however, to defend parts of his record, arguing that conventional forecasting was poorly equipped to anticipate the irrational risk-taking that can drive asset bubbles.
Born in Manhattan’s Washington Heights neighborhood in 1926, Greenspan first pursued music, studying at Juilliard and playing clarinet and saxophone before turning to economics at New York University, where he eventually earned a doctorate. He ran an economic consulting firm for decades, served as President Gerald Ford’s chief economic adviser and was appointed Fed chair by President Ronald Reagan in 1987. His personal and intellectual life also drew attention: he was influenced by Ayn Rand’s free-market philosophy, known for his dense and often cryptic style of public communication, and coined the phrase “irrational exuberance” in a 1996 warning about elevated stock prices. After leaving the Fed, he remained active as a consultant, author and television commentator, and in January 2026 joined other former senior officials in criticizing efforts by the Trump administration to investigate Fed Chair Jerome Powell, warning that such actions could undermine the central bank’s independence.
Greenspan’s legacy remains divided between admiration for a long stretch of growth and stability and blame for vulnerabilities that became painfully visible after he left office. Admirers say he helped shape decades of U.S. economic performance and maintain the Fed’s credibility. Detractors contend his policy approach encouraged excessive risk-taking, inflated bubbles and weakened safeguards in the financial system. Few central bankers, however, have left a larger imprint on markets, policymaking and the public understanding of the Federal Reserve.
