Greenspan at 100: the man who outlasted the dollar's longest boom — and the critique he never answered

Alan Greenspan, the 13th chairman of the US Federal Reserve, has died at the age of 100. Reports of his death on 22 June 2026 surfaced within hours across wire desks and crypto channels, each carrying the same biographical spine: five terms, four presidents, nineteen years in the chair. Greenspan ran the Federal Reserve from 1987 to 2006, a tenure that began under Ronald Reagan and ended under George W. Bush. He was the most consequential central banker of the post-Cold War generation, and arguably the most mythologised. The obituaries now being filed are correct on the facts and soft on the verdict.

The case for Greenspan is well-rehearsed and not wrong. He inherited a market in the aftershock of Black Monday, steered the Fed through the 1998 Long-Term Capital Management collapse, and held the line on inflation long enough to be called "Maestro." Under his watch the dollar retained its role as the world's reserve currency, US Treasury markets deepened into the deepest pool of collateral on the planet, and a globalised supply chain was financed in greenbacks. He is being remembered, accurately, as a steward of an extraordinary run of price stability.

The case against him is also well-rehearsed, and the early tributes are mostly declining to press it. The 2001 recession, the 2002–2006 housing mania, the savings-and-loan deregulation of the late 1980s, the explicit endorsement of derivatives markets in the 1990s — all happened on his watch. The "irrational exuberance" speech of 5 December 1996 raised the alarm and changed nothing; the Fed kept the policy rate accommodative, the regulatory posture stayed permissive, and the 2008 crisis arrived three years after Greenspan left the building. In his 2008 congressional testimony he conceded a flaw in his own ideology about self-correcting markets. The concession was real. The structural correction never came.

Three things are worth saying plainly while the framing is still being written. First, the "Great Moderation" — the period of low volatility Greenspan is credited with engineering — was, in significant part, the result of a credit boom financed externally. The US ran persistent current-account deficits, the rest of the world recycled dollars back into Treasuries, and the policy rate could stay low because the marginal buyer of American debt was a foreign central bank with a mercantilist reason to hold it. That is not a flaw in the chair's personality; it is a feature of a system the chair administered. Greenspan understood this. He said so in private. The public myth of the all-seeing technocrat who tamed the business cycle is a press construction, not a policy achievement.

Second, the dollar's primacy is a policy choice, not a law of nature, and Greenspan's tenure is the period in which Washington stopped questioning it. The euro did not emerge. The yen never internationalised. The renminbi was still effectively closed. The petrodollar recycling arrangement held. The Fed, in effect, was the world's central bank because the political class on both sides of the aisle decided the costs of that arrangement were bearable and the benefits were uncountable. Greenspan is being mourned by the same commentariat that now treats the dollar's reserve status as a permanent feature of the international system. The man is gone; the assumption lives.

Third, the technologies that broke the Greenspan framework were not invented in his tenure but were permitted to metastasise in it. Shadow banking, mortgage securitisation, off-balance-sheet vehicles, credit-default swaps — none of these are mysteries. Greenspan's own philosophy treated private risk-management innovation as self-policing. When that philosophy failed, the public absorbed the bill. The 2010 Dodd-Frank act, the Basel III regime, the stress tests — all of it is the slow institutional answer to a question the Greenspan Fed refused to ask in real time. The next crisis will not look like 2008. The institutional reflexes it will demand were built because of 2008.

The counter-narrative to the obituaries now being filed is the simplest one. Greenspan did not conquer inflation; he outsourced its suppression to a credit boom whose collapse he did not prevent. He did not invent the dollar's reserve role; he benefitted from it and administered it. He did not cause 2008, but the regulatory posture of his era made 2008 inevitable in shape if not in date. A serious accounting of his legacy owes the man his considerable craft and his genuine intellectual seriousness. It also owes the public a clearer account of the structural costs that were externalised during the long boom, and of the political economy that made those costs easy to ignore at the time and easy to forget now.

What remains genuinely uncertain is whether the historical record will eventually distinguish between the Greenspan who, in 2008, publicly admitted that his world view was "flawed," and the Greenspan who, in office, presided over the conditions that required the admission. The man is dead. The institutional architecture he shaped is alive, and it is being tested in real time by debt levels, geopolitical fragmentation, and the slow-motion diversification of the reserve system he once administered. The harder verdict will be written in those tests, not in the obituaries.

Desk note: Monexus ran this as opinion because the wire is producing elegy. The structural question — what Greenspan's tenure cost, and to whom — is not the question his admirers want to lead with, and not the question his critics are being platformed to ask. We asked it anyway, and attributed the biographical claims to the wire.
