When a man known as the 'God in the machine' of American finance dies at 100, the world stops to consider the power of central banking. Alan Greenspan, who chaired the US Federal Reserve from 1987 to 2006, was arguably the most influential central banker of his era, shaping not just the American economy but the global financial system. His passing at 100, due to complications of Parkinson's disease, has prompted reflection on a career that spanned boom, bust, and the very philosophy of economic management.
Alan Greenspan was the chairman of the Federal Reserve (the Fed), the central bank of the United States, under four presidents: Ronald Reagan, George HW Bush, Bill Clinton, and George W Bush. He served five terms, a tenure of 18 and a half years, just five months short of the longest in history. His job was to safeguard the US economy and keep the dollar sound, a role often described as the second most important in the country after the presidency. He brought a rigorous analytical discipline to monetary policy and helped establish what the Fed called 'the credibility that remains one of the Federal Reserve's most important assets.'

Greenspan's path to becoming the world's most high-profile banker was unusual. Born in New York City in 1926 and raised single-handedly by his mother, he was a talented clarinetist who studied at the Juilliard School and played with jazz great Stan Getz in the Henry Jerome Band. While other musicians smoked marijuana, Greenspan studied economics and did the band's accounts. He went on to earn bachelor's, master's, and doctoral degrees in economics—all from New York University—and became an apostle of free-market ideas, influenced by novelist Ayn Rand, who called him 'the undertaker' due to his dark suits. After decades running an economic consulting firm, he entered public service.
During his time at the Fed, Greenspan presided over the longest sustained period of US economic growth in a generation. He was widely credited with fostering prosperity and gained bipartisan support. But his legacy is deeply contested. Critics argue that an over-reliance on easy credit under his watch fuelled the dot-com bubble of the late 1990s and worse, the sub-prime mortgage crisis of 2008. After he left office, the US housing market collapsed, triggering a devastating financial crisis and the worst recession since the Great Depression. The Financial Crisis Inquiry Commission concluded that 'more than 30 years of deregulation and reliance on self-regulation by financial institutions, championed by former Federal Reserve chair Alan Greenspan and others, had stripped away key safeguards.' Greenspan later acknowledged he had made a mistake in believing banks could regulate themselves, but defended himself by arguing that traditional forecasting cannot account for the irrational risk-taking that feeds catastrophic price bubbles.
For UK readers, Greenspan's story matters because the Federal Reserve's policies have global ripple effects. The US central bank sets interest rates and influences money flows worldwide, affecting everything from the value of the pound to mortgage rates in Britain. The deregulation he championed—and the crisis that followed—reshaped financial regulation in the UK as well, prompting tighter oversight of banks and lenders. Moreover, his career illustrates the immense power and limitations of central banking, a lesson that resonates as the Bank of England and other central banks navigate their own challenges with inflation, growth, and credibility.
Q&A on Alan Greenspan
Q: What was Alan Greenspan's role at the Federal Reserve? As chairman of the Federal Reserve from 1987 to 2006, Greenspan set US monetary policy—controlling interest rates and the money supply—to manage inflation, employment, and growth. He was widely seen as an economic oracle, and markets hung on his every word.
Q: Why is Alan Greenspan considered controversial? Greenspan's critics blame his support for deregulation and easy credit for inflating the dot-com bubble and the 2008 financial crisis. The official inquiry into the 2008 crash said his policies stripped away key safeguards. He later admitted he was wrong to trust banks to self-regulate.
Q: How did Greenspan's early life shape his economic views? A former jazz musician, Greenspan was an apostle of free-market economics influenced by novelist Ayn Rand. His practical business insight from touring with a band and studying economics at New York University formed his belief in self-regulation and limited government intervention.
Greenspan's death closes a chapter in economic history, but the debates he sparked remain open. Central bankers today study his successes and failures as they grapple with the same fundamental questions: how much to regulate, how to spot bubbles, and when to intervene. His legacy is a cautionary tale about faith in markets—and a reminder that the most powerful policymakers are only human.
