Alan Greenspan, the Fed's Most Powerful Voice in a Generation, Dies at 100

A Century-Long Life That Shaped American Finance

Alan Greenspan died on Monday, June 22, at his home from complications of Parkinson's disease, his wife of 29 years, NBC News correspondent Andrea Mitchell, confirmed. He was 100 years old, having served as the 13th chairman of the Federal Reserve from 1987 to 2006. Few figures in modern American economic history cast as long a shadow — or sparked as much debate.

Greenspan helped define modern American capitalism from the final years of the Cold War through the dawn of the digital age, presiding over the Fed during one of the longest economic expansions in U.S. history, a boom stretching from 1991 to 2001. His reign at the central bank coincided with the so-called Great Moderation — a period of stability from the mid-1980s until 2007 marked by low inflation, stock market gains, and strong economic growth.

From Jazz Clubs to the Halls of Power

Greenspan was born to Jewish parents on March 6, 1926, in New York's Washington Heights, where his father was a stockbroker and financial analyst, and where the future Fed chairman grew up during the Great Depression receiving a quarter a week in allowance. His early ambitions had nothing to do with interest rates. He was a talented jazz musician who studied clarinet and saxophone at Juilliard before dropping out to join a touring jazz band — and then, in a pivot that would reshape American economic policy, turned to economics.

First nominated to the Federal Reserve by President Ronald Reagan in August 1987, Greenspan was reappointed at successive four-year intervals until retiring on January 31, 2006, after the second-longest tenure in the position, behind only William McChesney Martin. As Fed chair, he became known for offering often cryptic economic commentary that lawmakers, economists, and investors scrambled to interpret, while also championing a shift toward greater transparency by central bankers. Wall Street traders reportedly tracked the size of his briefcase before Fed meetings, convinced that a stuffed bag signaled major policy changes ahead.

Irrational Exuberance — and a Legacy Under Scrutiny

His comment in 1996 about investors' "irrational exuberance" initially shocked the markets, but the bubble didn't burst until 2001. Traditionally, central bankers respond to low unemployment by raising interest rates to ward off inflation — but Greenspan broke with that tradition and kept borrowing costs low, a strategy that Princeton economist Alan Blinder, who served under Greenspan on the Fed's governing board, recalled as watching the unemployment rate drift "lower and lower and lower" with still no inflation.

In 2011, the bipartisan Financial Crisis Inquiry Commission determined that the crisis was triggered in part by Greenspan's failure to discourage trade in securities backed by subprime mortgage loans amid an unsustainable housing boom and his promotion of financial industry deregulation. As The Economist reflected in a 2017 essay, "The main post-crisis criticism of Mr. Greenspan was that he was a naive believer in market efficiency, failing to pop bubbles in the late 1990s or mid-2000s and failing to regulate the financial sector properly."

A Final Chapter — and an Enduring Question

As recently as January 2026, Greenspan signed a joint statement with other former Fed and Treasury officials to denounce a criminal probe of Fed Chair Jerome Powell, demonstrating that even at 100 he remained engaged in the battles over central bank independence that defined his career. In 1997, he had married NBC journalist Andrea Mitchell in a ceremony officiated by the late Supreme Court Justice Ruth Bader Ginsburg. Mitchell said: "To me he was my husband, who shaped my life from our very first date in 1984," adding that "he had 'irrational exuberance' for baseball, the Washington Commanders, tennis, golf and music, especially jazz," and that "he will be remembered for his brilliance and his kindness."

The Federal Reserve, in its statement on Greenspan's death, said he "brought rigorous analytical discipline to monetary policymaking and helped establish the credibility that remains" one of the central bank's "most important assets." Ultimately, Greenspan will be remembered as both a maestro of monetary policy and a reluctant regulator — his legacy shaped by the boom he fostered and by the bust he failed to prevent. In an era when the independence of the Fed is once again under fierce political pressure, that complicated legacy feels more relevant than ever.
