Alan Greenspan dies at 100: the Fed chair who defined an era, and the debates he left unresolved

The wire obituaries began the same way they always begin, with the architectural vocabulary. Former Fed chair Alan Greenspan died at 100, and within hours the ledes had him shaping the post-Bretton Woods order, shepherding the dollar through stagflation, presiding over the productivity miracle of the 1990s. The numbers were there. So were the laurels. What the obituaries did not do, in their first pass, was put the word enabler next to the word architect.

That is the structural-economics story, and it is the one worth telling on the day the record catches up with the man. Greenspan did not invent the deregulatory turn of the late twentieth century, but he lent it the gravity of the central bank. He did not cause the housing bubble that broke in 2008, but he described derivatives he admitted he did not understand, then cut rates into a bubble he could see forming. He did not deregulate the savings-and-loan system, but he opposed the brakes when regulators tried to apply them. The age that bears his name is not only the age of low inflation. It is the age of three crises that did not have to metastasize the way they did, and of a Federal Reserve that learned, very late, that asset prices matter even when CPI looks tame.

The record on the page

Greenspan chaired the Federal Reserve from August 1987 to January 2006, longer than any predecessor in the modern era. He arrived as a market-friendly Republican appointed by Ronald Reagan, an avowed acolyte of Ayn Rand whose inner circle included objectivist commentators and Wall Street deregulators. He left under George W. Bush, with a hero's send-off in the financial press and a letter of confidence from a president who would, within two years, sign the Troubled Asset Relief Program into law.

The pre-2008 record is genuinely strong. The Volcker disinflation had ended by 1987, but its credibility had to be maintained, and Greenspan maintained it. The 1990-91 recession was shallow. The 2001 recession, painful for the labour market, lasted eight months and was followed by a productivity-driven expansion that pulled the federal budget close to balance. The Fed's reaction function, in those years, looked like competence at industrial scale. Greenspan's testimony acquired a near-canonical status. Bond markets moved on his vocabulary. The term Greenspan put entered the working language of every trading floor.

The problem is that the same record contains the seeds of what came after. In the late 1990s, Greenspan warned publicly about irrational exuberance, then raised rates only modestly. After the dot-com collapse, he cut the funds rate to 1 percent by June 2003 and held it there for a year, into a housing market already showing signs of leverage-driven acceleration. In 2005 he noted that the national savings rate had turned negative, an observation that, by his own later admission, signalled a bubble he had chosen not to puncture.

The speech in 2002 that should have been a pivot

There is a single paragraph that, read now, looks like the hinge of the era. In a 2002 speech, Greenspan noted that early indications of trouble in corporate governance had surfaced, and warned that the same financial innovation that hedged risk could also concentrate it. He was talking about derivatives. He was talking, obliquely, about the instruments whose notional volumes would dwarf global GDP before the decade was out.

The speech landed. The Federal Reserve did not act on it. Regulators did not act on it. The institutions that built the instruments that Greenspan could not model were not asked to slow down. Three years later, in his 2005 testimony, the chair acknowledged that the proliferation of new derivatives had made the financial system harder to read. By then, the housing complex was using those instruments to recycle leverage into mortgage origination at a pace that no supervisor could track. When the cycle turned, the recycling machine ran in reverse, and the damage spread through the same plumbing that had been sold as a stabiliser.

The 2008 crisis is not Greenspan's crisis alone. It is the product of a decade in which fiscal policy ran hot, supervisors were starved, and a culture of self-regulation became gospel on the buy side. But the central bank is the lender of last resort. Its job is to see what the market cannot, and to lean against the wind when the wind becomes a gale. Greenspan, by his own subsequent testimony to the Financial Crisis Inquiry Commission, identified the failure: he had assumed that self-interest, especially of banks, would protect their own shareholders. That assumption was wrong. He had said so in 2008, on the Hill, in language no chairman had ever used before.

The three crises he did not stop

There were three. The first was the dot-com bust, where the Fed cut too late and then cut too much, priming the next bubble. The second was the housing and credit bubble, where the Fed cut into a build-up that its own staff could see and chose to look through. The third was the run on the shadow banking system in 2008, where the plumbing the Fed had tolerated for a decade became the conduit for contagion, and the institution had to invent emergency facilities overnight to contain the damage it had not prevented.

Each of these was, in its way, a foreseeable outcome of the regime Greenspan ran. Loose money does not always cause bubbles, but it tends to find the marginal corner of the system where leverage is least policed. In 1999 and again in 2004, the marginal corner was housing. The Fed's own research, in the years after 2008, identified the global savings glut as one driver of the low-rate environment; it also identified, more quietly, the domestic policy choices that had failed to lean against the build-up of household debt. Both stories are true. Greenspan presided over the version of the second story that ended in the worst financial crisis since the Depression.

His defenders point out, fairly, that the economy he bequeathed his successor included the tools that Ben Bernanke would deploy in 2008 and 2009, and that the recovery from the crisis was, by historical standards, fast. That is correct. It does not resolve the question the obituaries have to face. A central bank can be both competent and structurally permissive. Greenspan was both. The permissiveness is what his successors, including Bernanke and Janet Yellen, spent the next decade trying to unwind through stress tests, balance-sheet policy, and the slow reintroduction of liquidity constraints that had been allowed to lapse.

What the record still owes

The unresolved debates are not biographical. They are operational. The first is whether a central bank can identify asset-price bubbles in real time and lean against them without misreading the data; Greenspan's tenure suggests the answer is rarely, and that the policy implication is to lean earlier and harder than feels prudent. The second is whether self-regulation by financial institutions is a credible substitute for supervision. The 2008 record says no. The third is whether the Fed's dual mandate, as interpreted in the 1990s and 2000s, gave enough weight to financial stability when asset prices were inflating and CPI was quiet. The post-2008 reforms say it did not.

These are the debates Greenspan left behind, not because he failed to settle them but because his career made them unavoidable. The next chair, whoever that is, will inherit a balance sheet that bears the marks of those debates, and a supervisory architecture that exists because the previous one did not. Greenspan did not build that architecture. He did not have to. His successors did, in his shadow.

Desk note: Wire obituaries framed Greenspan as the architect of a successful era. Monexus runs the record the other way as well: the man who described the risks he could not see, and chose the policy mix that produced the crises that followed.
