Alan Greenspan, the former chairman of the Federal Reserve whose tenure spanned nearly two decades, died on Monday at the age of 100. His leadership of the U.S. central bank, from 1987 to 2006, elevated the Fed’s public profile and shaped economic policy in ways that continue to influence the institution and markets today.
Greenspan’s tenure was marked by significant achievements, including sustaining low inflation around 2 percent following the high inflation era addressed by his predecessor, Paul Volcker. He presided over the longest economic expansion in U.S. history at the time, from 1991 to 2001. For many Americans, Greenspan became synonymous with the Federal Reserve itself, viewed as a steady hand navigating complex economic landscapes. Wall Street and the public alike tuned into his speeches and testimony, coining phrases such as “irrational exuberance” to capture his warnings about frothy markets.
His approach combined a deep understanding of economic theory with a pragmatic temperament, which helped him manage political pressures and uncertainty. Unlike earlier Fed chairs drawn from backgrounds in banking, law, or public service, Greenspan was an economist who emphasized the role of human psychology—what he called “animal spirits”—in economic cycles. He resisted adherence to any single economic doctrine, instead drawing on diverse theories and real-world data to shape policy decisions.
Despite the successes, Greenspan’s legacy remains contested. He was praised for his role in fostering economic growth but also faced criticism for policies that some say contributed to financial vulnerabilities exposed in the crisis that followed his departure. Greenspan himself expressed mixed feelings about the outcomes associated with his tenure, stating he received undue credit for booms and unjust blame for later collapses.
Notably, Greenspan was cautious about aggressive monetary easing. He cut interest rates sharply after crises like the 1987 stock market crash and the 1998 Russian default, actions credited with stabilizing markets but also linked to encouraging risk-taking—earning the nickname of the “Greenspan put.” Even as he lowered rates to historic lows of 1 percent in 2003, he reportedly felt uneasy, holding a personal aversion to overly accommodative policy. Unlike later Fed chairs, he refrained from pushing rates to zero.
Colleagues and observers recall Greenspan not as an aloof technocrat but as an intellectually engaged and sometimes witty figure, committed to mastering economic ideas and sharing insights. His blend of skepticism about rigid theory and attention to human behavior distinguished his leadership of the Fed during a transformative period in U.S. economic history. As the institution he led continues to navigate new challenges, Greenspan’s complex influence remains a subject of study and debate.
