Alan Greenspan, Former Fed Chairman, Dies at 100

Alan Greenspan, the former chairman of the U.S. Federal Reserve who presided over the longest economic expansion in American history and became one of the most influential — and controversial — central bankers of the modern era, has died at the age of 100. Greenspan passed away on June 22, 2026, at his home in Washington, D.C., from complications of Parkinson’s Disease, his wife, NBC News journalist Andrea Mitchell, confirmed.

“He was a giant of a man who helped shape the U.S. economy for decades under presidents of both parties, but was always honest in acknowledging his mistakes,” Mitchell said in a statement. “To me he was my husband, who shaped my life from our very first date in 1984.”

The Maestro’s Rise

Born on March 6, 1926, in New York City’s Washington Heights to Jewish parents, Greenspan’s path to the pinnacle of global finance was anything but conventional. Before becoming an economist, he studied clarinet and saxophone at the Juilliard School and performed in Woody Herman’s jazz band. He went on to earn bachelor’s and master’s degrees in economics from New York University by 1950, eventually receiving his Ph.D. in 1977 at age 51.

Greenspan served as chairman of President Gerald Ford’s Council of Economic Advisers from 1974 to 1977 before being appointed Federal Reserve Chairman by President Ronald Reagan in 1987. He would go on to serve under four presidents — Reagan, George H.W. Bush, Bill Clinton, and George W. Bush — making his tenure the second-longest in Fed history at 18 years and five months.

His first major test came just 69 days into the job. On October 19, 1987 — “Black Monday” — the Dow Jones Industrial Average plunged 22.6% in a single day. Greenspan’s swift response, affirming the Fed’s readiness “to serve as a source of liquidity to support the economic and financial system,” helped stabilize markets and earned him the nickname “the Maestro,” popularized by Bob Woodward’s biography.

The Boom Years and ‘Irrational Exuberance’

Throughout the 1990s, Greenspan presided over the longest economic expansion in U.S. history. His willingness to keep interest rates low even as unemployment fell — breaking with traditional central banking orthodoxy — fueled a technology-driven boom that reshaped the American economy.

His most famous moment came on December 5, 1996, when he asked in a speech: “How do we know when irrational exuberance has unduly escalated asset values?” The phrase sent the Tokyo stock market down 3% immediately and became synonymous with Greenspan’s influence over global markets. As NPR noted, Greenspan was “the rare celebrity among central bankers,” with ordinary Americans hanging on his every word.

Greenspan also became famous for “Fedspeak” — a deliberately opaque communication style designed to avoid moving markets. He later admitted in a 2007 CNBC interview that it was “a language of purposeful obfuscation” to avoid answering questions he couldn’t address directly.

A Contested Legacy

Greenspan’s reputation was profoundly complicated by the 2008 global financial crisis, which struck two years after his retirement. Critics argue that his low interest rate policies in the early 2000s fueled the housing bubble, and his opposition to regulating financial derivatives created the conditions for the worst economic downturn since the Great Depression.

In 2005, Greenspan dismissed warnings of a housing bubble. After the crisis erupted, he acknowledged before Congress: “I found a flaw in the model.” He told USA Today in 2007: “Sometimes I get criticized, and I deserve to be criticized, and that’s part of the game. But this one, I’m innocent.”

Ben Bernanke, Greenspan’s successor who guided the economy through the 2008 crisis, offered a measured tribute: “He was a great central banker who helped lead his country through almost two decades of prosperity. I always found him generous with his time and insights. We are still learning from him, even if he is no longer with us.”

The Federal Reserve noted Greenspan’s passing “with deep sadness,” saying his “contributions to monetary policy and economic thought left a lasting mark on this institution, on the broader field of economics, and on the country.”

Later Years and Political Engagement

After retiring from the Fed in January 2006, Greenspan remained active through his consulting firm, Greenspan Associates, and published two books: “The Age of Turbulence” (2007) and “The Map and the Territory 2.0” (2013).

He was unafraid to wade into political debates. In December 2019, he criticized President Donald Trump’s attacks on the Federal Reserve, telling CNBC: “He’s wrong in even discussing the issue.” During Trump’s second term, in January 2026, Greenspan joined former Fed and Treasury officials in signing a joint statement denouncing a criminal investigation into Fed Chair Jerome Powell, calling it “an unprecedented attempt to use prosecutorial attacks to undermine that independence.”

A Life in Full

Greenspan married Andrea Mitchell in 1997 in a ceremony officiated by the late Supreme Court Justice Ruth Bader Ginsburg. Mitchell, in her statement, remembered his “irrational exuberance” for baseball, the Washington Commanders, tennis, golf, and jazz. “He will be remembered for his brilliance and his kindness. Being his life partner was the joy of my life.”

Greenspan’s life spanned nearly a century of American economic history — from the Great Depression through the post-war boom, stagflation, the Great Moderation, and the 2008 crisis. His intellectual journey was shaped by the free-market philosopher Ayn Rand, to whom he was introduced by his first wife, and by his mentor, former Fed Chairman Arthur Burns.

What Comes Next

Greenspan’s death comes at a pivotal moment for the Federal Reserve under newly appointed Chair Kevin Warsh, who has signaled a return to the “Greenspan model” by eliminating forward guidance from the central bank’s policy statements — a departure from the transparency-focused approach of Greenspan’s successors. The debate over Greenspan’s legacy — whether he was a maestro who fostered prosperity or an architect of crisis — will likely intensify as economists and historians assess his place in the pantheon of central bankers.

As the man himself once said: “Fear and euphoria are dominant forces, and fear is many multiples the size of euphoria.” Alan Greenspan understood those forces perhaps better than anyone — and helped shape the world they created.
