Alan Greenspan, the influential economist who steered the U.S. Federal Reserve through nearly two decades of economic expansion, crisis management and policy debates, marked his 100th birthday on March 6, 2026, entering the rare company of living centenarians who shaped modern American finance.

Born March 6, 1926, in New York City's Washington Heights neighborhood to Herbert Greenspan, a stockbroker, and Rose Goldsmith, Greenspan grew up during the Great Depression, an experience that profoundly influenced his views on markets, risk and economic stability. His parents divorced when he was young, and he was raised primarily by his mother in modest circumstances.

Greenspan's early aptitude for numbers was evident; at age 5, he could recite baseball batting averages and perform complex mental calculations. He pursued economics at New York University, earning a bachelor's degree in 1948, a master's in 1950 and beginning doctoral studies at Columbia University under Arthur Burns, who later became Fed chair himself. Greenspan never completed his Ph.D. but built a formidable career in consulting and policy.

In the 1950s and 1960s, he founded Townsend-Greenspan & Co., an economic consulting firm, and served as an adviser to President Gerald Ford's Council of Economic Advisers from 1974 to 1977. Known for his libertarian leanings and association with Ayn Rand's circle in the 1950s, Greenspan advocated free markets while acknowledging the need for central bank oversight.

President Ronald Reagan appointed him Fed chair in August 1987, succeeding Paul Volcker. Greenspan's 18½-year tenure — the longest in Fed history — spanned four presidents: Reagan, George H.W. Bush, Bill Clinton and George W. Bush. He navigated the 1987 stock market crash, the early 1990s recession, the dot-com boom and bust, the September 11 attacks and the housing bubble buildup.

Often called the "Maestro" after Bob Woodward's 2000 biography, Greenspan's low-interest-rate policies in the 1990s fueled what became known as the "Greenspan era" of prosperity: low inflation, strong growth and falling unemployment. He famously warned of "irrational exuberance" in stock markets in 1996, a phrase that entered the financial lexicon.

Critics later blamed his accommodative stance for contributing to the 2008 financial crisis, arguing easy money encouraged excessive risk-taking and the subprime mortgage boom. Greenspan defended his record in congressional testimony and his 2007 memoir, *The Age of Turbulence*, insisting the crisis stemmed from broader systemic failures rather than Fed policy alone.

After stepping down in January 2006, succeeded by Ben Bernanke, Greenspan founded Greenspan Associates LLC, offering economic consulting. He authored additional books, including *The Map and the Territory* (2013) and *Capitalism in America: A History* (2018) with Adrian Wooldridge. Public appearances dwindled in recent years, though he remained engaged in private advisory work.

As of 2026, Greenspan's net worth is estimated at $20 million, derived from consulting fees, speaking engagements, book advances — including an $8.5 million deal for his memoir — and investments. He splits time between New York City and Washington, D.C., with his wife, NBC News correspondent Andrea Mitchell, whom he married in 1997.

Greenspan has largely withdrawn from the spotlight, but his name resurfaced in early 2026 amid debates over Federal Reserve independence. In January, he joined former chairs Ben Bernanke and Janet Yellen, along with ex-Treasury secretaries, in signing a statement criticizing "prosecutorial attacks" on the central bank amid political pressures from President Donald Trump. The group warned that undermining Fed autonomy could erode public confidence in monetary policy.

Recent commentary has drawn parallels between the current economic environment and the 1990s under Greenspan. With President Trump's nominee Kevin Warsh poised to succeed Jerome Powell, some analysts question whether Warsh can replicate the "Greenspan put" — the perception that the Fed would intervene to support markets — in an era of artificial intelligence-driven growth and structural shifts.

Greenspan's health details remain private, but reports indicate he is doing well for his age. A 2018 Twitter hoax falsely claimed his death; Mitchell quickly debunked it, saying, "Alan's doing great." No similar rumors have circulated recently, and his milestone birthday has prompted reflections on his legacy rather than health concerns.

Economists and historians continue to debate Greenspan's record. Supporters credit him with mastering inflation without derailing growth, fostering the longest peacetime expansion in U.S. history. Detractors argue his reluctance to tighten policy aggressively contributed to asset bubbles. His cryptic, data-heavy communication style — once described as "Greenspeak" — became legendary, often leaving listeners parsing nuanced statements for policy hints.

At 100, Greenspan's life spans transformative periods: from the Depression through World War II, the postwar boom, the Cold War, globalization and the digital age. His influence persists in discussions of central banking, fiscal policy and market psychology.

As markets face volatility in 2026 — with oil surges, labor market surprises and geopolitical tensions — Greenspan's era offers lessons on balancing growth, stability and caution. His centennial arrives at a time when the Fed's role remains central to economic debates, underscoring the enduring impact of the man once dubbed the second-most powerful figure in America.

Friends, colleagues and admirers marked the occasion quietly, with tributes highlighting his intellectual rigor, longevity and contributions to public service. Greenspan himself has not issued public statements on his birthday, consistent with his low-profile approach in recent years.
