Alan Greenspan, who served as Chairman of the Federal Reserve from 1987 to 2006, died at the age of 100 from complications of Parkinson’s Disease. His wife, NBC News correspondent Andrea Mitchell, announced his death. Greenspan had celebrated his centenary in March and remained an active economic commentator into his late nineties, criticising the Trump administration’s populism as “a shout of pain” and warning as recently as 2023 that the Biden administration was raising interest rates too fast. The man who coined “irrational exuberance” — the phrase he applied to the dot-com bubble in a 1996 speech — had presided over five presidential administrations, three recessions, the savings and loan crisis, the 1997 Asian financial crisis, the dot-com collapse, and the September 11 attacks. He managed all of them with a reputation for steady hands and analytical precision that made him, in the phrase of Alan Blinder, “the second most important post after the presidency.” The 2008 global financial crisis, which his own regulatory philosophy had helped create, did not kill his reputation. It merely complicated it — permanently.
The received wisdom
The progressive and Keynesian critique of Greenspan is by now almost ritualistic, but it has a core of truth that his admirers have sometimes been too quick to minimise. The case against him runs roughly as follows: his post-9/11 rate cuts, which kept the federal funds rate at historically low levels from 2001 to 2004, helped inflate a housing bubble whose collapse triggered the worst financial crisis since the Great Depression. His philosophical hostility to regulating derivatives and complex financial instruments — rooted in his Ayn Rand-inflected belief that markets would always self-regulate in their own interests — left the financial system structurally vulnerable to exactly the kind of cascading failure that materialised in 2007 and 2008. In his October 2008 Congressional testimony, Greenspan admitted he had found “a flaw” in his ideology — that he had placed too much faith in the self-correcting capacity of free markets — a concession remarkable for its intellectual honesty and devastating for what it implied about two decades of policy. Paul Krugman’s verdict — that Greenspan “didn’t raise interest rates to curb the market’s enthusiasm” during the dot-com boom, “then tried to clean up the mess afterwards” — became the canonical left critique and has not been substantially refuted.
A different read
What that critique tends to omit is the scale of what Greenspan got right, and the genuine difficulty of the choices he faced. He was appointed by Ronald Reagan in August 1987 and two months later was handed his first crisis: the Black Monday stock market crash of October 1987, which wiped more than 30 percent off share prices in a single day — a decline proportionally larger than any single-day fall in 1929. His response — a confidence statement and the provision of cheap credit — calmed markets within days. He managed the savings and loan crisis without triggering a broader bank run, guided the economy through the Gulf War’s oil shock, helped engineer the soft landing after the 1997 Asian crisis, and presided over the extraordinary growth period of the late 1990s under Clinton, during which US GDP contracted only once across his entire tenure.
More important, and more frequently forgotten by his critics, is the context in which his regulatory philosophy operated. The derivatives market that proved so dangerous in 2007-08 was regulated under a framework that was, at the time, broadly supported across the political spectrum. The Clinton administration’s 1999 repeal of Glass-Steagall — which had separated commercial and investment banking since the 1930s — was championed not only by free-market Republicans but by Treasury Secretary Larry Summers and signed by Bill Clinton. The Community Reinvestment Act, expanded under Clinton, created pressures on lending institutions to extend mortgages to borrowers who, under traditional underwriting standards, would not have qualified. These are not exculpatory facts, but they are relevant ones: Greenspan’s deregulatory instincts operated in a Washington consensus that included figures from both parties who shared, in varying degrees, his optimism about financial innovation and market self-correction.
The deeper question that Greenspan’s death raises is one that financial policy has still not resolved: what is the appropriate role of a central bank in managing asset price inflation versus consumer price inflation? Greenspan’s intellectual framework — the “clean up” doctrine, under which the Fed should not attempt to deflate asset bubbles preemptively but should simply manage the fallout when they burst — was not simply an ideological prejudice. It reflected a genuine technical difficulty: identifying a bubble in real time, before it bursts, requires a degree of certainty about asset valuations that no model can reliably provide, and prematurely tightening to deflate what turns out not to be a bubble carries substantial costs. The Federal Reserve under successive chairs has not actually solved this problem, and the current situation — with the Warsh-led Fed navigating inflationary pressures from an oil shock driven by a Middle Eastern conflict — illustrates how persistently difficult the task is.
Greenspan began his intellectual life as a Juilliard-trained clarinettist who toured with a jazz band before discovering economics. He ended it as the man who told Congress he had found a flaw in the ideology he spent fifty years constructing. That arc — from ideological confidence to public confession of error — is rarer in public life than it should be. His legacy is genuinely contested, and the contest is genuinely important: the question of how much markets can self-regulate, and what happens when they cannot, is not a historical question. It is the defining question of every monetary crisis that has followed him, and every one that will follow those.
What to watch
Watch how Greenspan’s death shapes the current Federal Reserve debate. The Warsh Fed’s hawkish posture on inflation — holding rates despite a sluggish jobs market — operates in a post-Greenspan intellectual environment that is, in some ways, a direct reaction to the “clean up” doctrine: central banks now explicitly discuss asset price stability in ways Greenspan largely avoided. Watch whether the eulogies acknowledge the 2008 admission or paper over it — the tone of official commemoration will reveal how deeply the political establishment has absorbed the lessons of what went wrong. Watch also the academic economics literature: a generation of scholars who built their careers on post-2008 critique of the Greenspan model are now the senior voices in the discipline, and their assessment will shape how monetary policy is taught for the next generation.
