Greenspan at 100: the life, the legacy, the verdict still pending

Alan Greenspan, the Federal Reserve chairman who presided over nearly two decades of American monetary policy across four presidencies, died on the morning of 22 June 2026 at his home from complications of Parkinson's disease. He was 100. His wife, Andrea Mitchell, the longtime NBC News correspondent, confirmed the death in a statement reported by Reuters, the BBC, the Jerusalem Post, and France 24. The obituaries landed within the same hour across continents — a measure of how thoroughly the man, and the institution he ran, had fused into the architecture of late-twentieth-century global finance.

The verdict on that chairmanship, however, remains one of the most contested in modern economic history. Greenspan was hailed as the maestro of the great moderation when he stepped down in January 2006. Barely two years later, the subprime crisis broke and the reputation that had once looked unassailable collapsed into the rubble of Lehman Brothers and a $700 billion US Treasury rescue. A century on, the obituary pages are doing what they always do for central bankers: weighing a life's work against the crises that bookended it. The honest answer is that the case is still open.

The man and the institution

Greenspan joined the Federal Reserve Board in 1984 and was elevated to chair in August 1987, succeeding Paul Volcker. He served under Ronald Reagan, George H. W. Bush, Bill Clinton, and George W. Bush — a tenure that spanned the 1987 stock-market crash, the early-1990s recession, the long expansion of the 1990s, the dot-com bust of 2000–02, the post-9/11 easing cycle, and the housing mania of the mid-2000s. He left the chair in February 2006, handing Ben Bernanke a board that already showed the fissures that would, within thirty months, become a chasm.

The BBC's obituary calls him "the architect of the modern American economy," a phrase that captures the popular framing without quite resolving it. France 24's two wire pieces cast him as a figure with "a divided legacy." The Jerusalem Post emphasised his long Jewish identity and his earlier career as an Ayn Rand–associated economist in the 1960s and 1970s. Each of these framings is defensible, and each only captures a piece of him. What binds them is the recognition that the man who set US interest rates became, for a generation, the most consequential economic actor in the world — not because he had vast statutory powers, but because the credibility of the dollar and the depth of US capital markets made his word move them.

What the chair actually did

The conventional account of Greenspan — the one that dominated his retirement in 2006 — credited him with two policy innovations. The first was "front-loading" pre-emptive rate cuts, most famously in 1998 after the Russian default and the collapse of Long-Term Capital Management, when the Fed cut rates three times to keep a financial shock from metastasising into a real-economy downturn. The second was the management of the so-called "great moderation," the long period of low inflation and falling volatility that preceded the crisis.

The critique that hardened after 2008 was not that these tactics were wrong, but that they were systematically mispriced. By repeatedly rescuing markets from the consequences of their own risk-taking, the argument ran, the Greenspan Fed trained the financial system to take more of it. The 1998 LTCM intervention became a template; the 2001 response to the dot-com shock extended it; the post-2003 reluctance to tighten into the housing bubble completed it. By 2006, the system had internalised the expectation of a put.

It is worth saying plainly that this critique is contested, and not only by free-market ideologues. The IMF and the Bank for International Settlements published papers during the late 2000s arguing that the global savings glut, the integration of China into world trade, and the demographic profile of the industrial world were doing most of the work in suppressing long-term Treasury yields and pushing investors out the risk curve. On that reading, the Fed's accommodative stance was responding to forces that any chair would have had to accommodate. The 2008 crisis was, in that framing, less the consequence of a particular chairman's psychology than of an accumulation of global imbalances that no single institution could offset.

The honest reading is that both stories are partly true, and that the share attributable to each will probably never be settled empirically. What can be said is that the chair who said in 1996 that he detected "irrational exuberance" in US equity markets — and then did essentially nothing about it — was the same chair who, in 2005, called the rise in housing-related derivatives "unprecedented" while declining to use the supervisory tools at his disposal. The pattern is unmistakable, whatever the underlying explanation.

The structural frame: dollar politics and the cost of credibility

Greenspan's chairmanship sat at the high-water mark of a particular arrangement of the world — one in which the US current-account deficit could be financed indefinitely by foreign savings, the dollar could function as the default reserve currency without serious challenge, and the Federal Reserve could set the marginal price of risk for the entire global financial system. By the time he left the chair, that arrangement was already under strain. The subprime crisis of 2007–08 was the proximate trigger, but the deeper tension — between a country that consumed more than it produced and a financial system that priced that gap as a feature rather than a bug — was structural.

The point worth dwelling on is that Greenspan did not build this system, and he could not have dismantled it. What he did, in his years at the helm, was give it a particular temper: an instinct for liquidity, a tolerance of leverage, and a deep scepticism of any rule that would have constrained the Fed's discretion in real time. The Dodd-Frank Act of 2010, the Basel III capital regime, the FSOC, the stress tests — all of these are, in one sense, the legislative rebuttal of a chairmanship that the post-crisis Congress decided, on balance, had leaned too far toward forbearance. Greenspan himself acknowledged as much in testimony to the House Committee on Oversight and Government Reform in October 2008, in what remains one of the most extraordinary public concessions by a former Fed chair: yes, he had found a flaw in his model of how markets self-regulate. The phrase "state of mistaken presumption" entered the lexicon.

That concession, and the man who made it, are the reason the verdict on Greenspan remains open. He was ideologically committed to the view that markets allocate capital better than regulators do, and he administered a regulatory perimeter that the crisis exposed as inadequate. He also, throughout his career, displayed a willingness to revisit first principles in the face of evidence — the LTCM intervention, the post-9/11 cuts, and the eventual public revision of his own intellectual priors are all instances of a mind willing to break with itself. Whether that openness, in the long run, excuses the larger failure of supervision is precisely the question the obituaries are wrestling with.

The longer shadow: a chair, then a model

The Greenspan era is sometimes treated as a transitional one — the bridge from the Volcker disinflation to the Bernanke–Yellen–Powell regime of explicit forward guidance, balance-sheet policy, and now, increasingly, the political weaponisation of the central bank itself. There is truth in that, but it undersells the more durable influence. The "Fed put" is not, strictly, a Greenspan invention — the concept predates him — but his tenure normalised it. The doctrine of pre-emptive easing under the chair's discretion is now baked into how the institution talks to markets, even when the explicit inflation target contradicts it.

The point matters outside the United States. For two decades, the assumption that a Greenspan-led Fed would cut rates into a panic, and that the dollar system would absorb the resulting capital flows, was a load-bearing assumption of the entire emerging-market world — from the Mexican peso crisis of 1994–95 to the East Asian crises of 1997–98, to the Brazilian and Argentine defaults of the early 2000s, to the resource-exporting economies of the mid-2000s. When the put was withdrawn in 2008–10, the cost of its absence was borne not only in the United States but in the eurozone periphery, in Iceland, in the Gulf, and in a generation of emerging-market policymakers who rewrote their macro frameworks around the lesson that the Fed's discretion was a global externality. That lesson has, in turn, shaped the current debate about de-dollarisation, reserve diversification, and the political risk of dollar-dependence — a debate that has only intensified since 2022.

In this sense, Greenspan's legacy is not just an American story. It is a story about the conditions under which the world organised its financial life between the end of the Cold War and the crisis of 2008, and the fault lines that have opened up since.

The verdict still pending

A century is a long time, and the man who died this morning in Washington spent most of it inside the institutions that shaped the modern American economy. He was a Randian in his youth, a Republican operative, a corporate consultant, a Fed governor, a chair whose name was, for a stretch, a verb — "to Greenspan" meaning, in trader argot, to talk markets down with a single adverb. He was also a man who watched the model he believed in break, in public, on his own watch.

The obituaries are correct to describe the legacy as divided. France 24 puts it bluntly: a chairman who presided over an "unprecedented period of American economic expansion" but was "later faulted" for the conditions that produced the worst financial crisis since the Great Depression. The Reuters wire emphasises both the praise he received on retirement in 2006 and the blame that followed. The BBC highlights the global reach. The Jerusalem Post emphasises the man behind the office. None of these is wrong; none of them is complete.

What the obituaries cannot yet do is adjudicate the structural question — whether the architecture Greenspan administered was, on balance, a stabilising or destabilising presence in the world economy. That is a question the next decade of research, and the next generation of central bankers, will have to answer. The man who could have spoken to it most directly is now, as of 22 June 2026, silent.

The honest thing to say is that the verdict on Greenspan is not a verdict on Greenspan alone. It is a verdict on the dollar system he was given to run, the political constraints he operated under, and the intellectual confidence — the over-confidence, some would say — of an era that believed the great moderation would last.

It did not. The reckoning that followed is still being worked through, in the United States and well beyond it. Greenspan lived long enough to see his own model fail in public, and long enough to revise it. That is, in the end, the most that can be asked of any public figure: a willingness to be proven wrong in plain sight, and to keep working in the aftermath.

Desk note: Wire obituaries from Reuters, the BBC, France 24, and the Jerusalem Post converged on the same death notice within roughly 90 minutes on the morning of 22 June 2026. Monexus has reported the death as confirmed by his wife, Andrea Mitchell, per those wires, and has not independently verified medical details beyond what the family statement provides. The longer verdict on Greenspan's chairmanship — and on the dollar system he administered — is treated here as a live question, not a closed one.
