Greenspan's century ended on a Sunday. The argument he defined has only just begun.
The architect of the long boom died at 100. The idea that a single unelected banker could fine-tune a continental economy has died with him, in everything but name.
Alan Greenspan died at 100 on 22 June 2026, at his home, of complications from Parkinson's disease. He had lived long enough to become a museum piece of himself: cited as authority by everyone who once treated him as oracle, and as cautionary tale by everyone he had helped bankrupt. Mitchell, his wife, announced the death. The fact that the announcement was carried by mainstream wire copy from France 24, BBC World, the Jerusalem Post, CGTN, and the X accounts of press agencies inside the same half-hour tells you the story of his reach. Greenspan did not belong to one country, one party, or one theology of money. He belonged to the twentieth century's particular faith that an economy could be steered by a patient, credentialed hand.
For almost two decades, as chairman of the Federal Reserve from 1987 to 2006, he was the world's most high-profile banker. The press treated him as oracle; markets treated him as referee. The argument he embodied — that the proper job of a central bank is to remove risk from the system, and that an unelected expert with the right temperament can do it better than the political branches ever could — outlasted his tenure and outlived its plausibility long before he did. What we have learned in the two decades since is not that the argument was wrong, but that it was bounded. Its ceiling was the year 2007, and we have been living in the rubble of that ceiling ever since.
The man was the doctrine
Greenspan did not invent central-bank independence. The Federal Reserve had operated at arm's length from the Treasury since the 1951 Accord, and Volcker had already demonstrated, in blood, that a chairman willing to inflict a recession could tame inflation. What Greenspan added was rhetorical mastery. He translated Volcker's blunt instrument into a continuous, anticipatory art: lowering rates before the data confirmed the slowdown; raising them before the data confirmed the boom; speaking in Fedspeak dense enough to be quoted without ever being pinned. He presided over what is still called the Great Moderation — lower volatility in output, lower volatility in inflation, and an uninterrupted expansion that, by the time he left office in January 2006, had lasted longer than any in American history.
The achievements were real, and they deserve a column inch. Unemployment fell, inflation stabilised, financial markets deepened. But the doctrine that produced them was also, in retrospect, a doctrine of deferred accounting. Asset bubbles, by Greenspan's own repeated public judgment, were not the central bank's problem to prick. The Fed's job was the price level and the cycle. If a housing bubble was inflating, that was a matter for regulators he had no formal authority over; if a credit bubble was inflating in the wholesale markets, the same. The expertise, in other words, was selective. The Fed was expert at the parts of the system it had chosen to be expert at.
The dissenters were right, and they lost
The mainstream wire obituary will, correctly, note the divided legacy. It will record the deregulatory instinct that Greenspan brought from his Ayn Rand–influenced youth, and the role of low rates and weak supervision in the financial wreckage of 2008. It will quote his 2008 congressional testimony that he had "found a flaw" in his ideology of self-regulation. It will be polite about the way that flaw was discovered: only after the building was on fire.
What the obituaries will not say, because obituaries rarely do, is that the warnings were there. Robert Shiller was warning about a housing bubble from the early 2000s and was treated, at the time, as a curiosity. The Bank for International Settlements in Basel was publishing research on credit booms that went largely unread in Washington. Within the Fed itself, regional presidents including the Dallas and Minneapolis chiefs were flagging froth, and were outvoted. The institutional memory of the late Greenspan years is one in which the warning system functioned and the political-economy of response did not: a single chairman's worldview, ratified by a committee that had been selected for compatibility with it.
The structural frame, in plain language
The lesson is not that experts cannot be trusted. It is that the institutional design that vests extraordinary discretion in a single figure, accountable only to Congress and to a confirmation process that has become performative, will tend to compound the errors of its current occupant. Greenspan's Fed was, in formal terms, no more powerful than Bernanke's Fed or Powell's Fed. In practice, under his tenure, the institution behaved more like the brain of a single economist than like a committee of disagreeing ones.
This matters now because the present generation of central bankers is operating inside a different macro world and using tools designed for the last one. The 2008 crisis, the 2020 fiscal expansion, the 2021–2022 inflation, and the post-pandemic rate cycle have together produced a regime in which the neutral rate is uncertain, fiscal dominance is back on the table, and the political legitimacy of independent monetary policy is contested as it has not been since the 1970s. Greenspan's claim was that a low-volatility economy was a high-credibility economy. The present dispensation is testing whether credibility can survive the kind of supply shocks, energy transitions, and geopolitical fragmentation that the low-volatility era was, in part, the product of.
Stakes, over a horizon that is shorter than it looks
The reading of the obituaries that matters least is the one that treats Greenspan as a personal story. The reading that matters most is the one that asks what kind of central banking survives him. The answer, for the moment, is a hybrid: rate-setting committees with greater internal dissent, balance-sheet tools that arrived by emergency and have stayed by inertia, and a political environment in which every inflation print is now read as a verdict on competence. The Greenspan model — one person, one doctrine, one temperament — is not coming back. What is coming back, slowly, is the older recognition that monetary policy is a political economy, not just a technocratic exercise in Taylor-rule optimisation.
What remains genuinely uncertain is whether the institutional learning has matched the scale of the shock. The Fed has weathered the inflation of 2021–2022, more or less, with its independence intact. It has not yet had to make a decision under conditions in which the political branches disagree about the central bank's mandate, the public disagrees about the mandate, and the underlying economy is being reshaped by industrial policy, decarbonisation, and a reshoring of supply chains. That is the regime Greenspan's successors will actually have to govern in. The fact that he died on a Sunday morning, peacefully, and at the age at which the body can no longer tell the man anything about his reputation, is the only part of the story that is not a cautionary tale.
This publication treats the Greenspan obituaries as a starting point, not a verdict. The wire pieces register the death; the harder question is what kind of central bank the world is building in his absence.
