What Would Greenspan Do?

Before he was the most powerful banker on Earth, Alan Greenspan was a jazz kid from Washington Heights. Born March 6, 1926, he spent his teenage years at the Juilliard School, training on the clarinet and saxophone. He played in Henry Jerome’s Orchestra alongside a young Stan Getz — yes, that Stan Getz, the tenor saxophone legend who defined cool jazz. Spot that lanky clarinetist in a Village club in 1944 and you would have seen a musician with good timing and better instincts. You would not have guessed he would spend eight decades trying to tame the economic future of the world.

But the arc bent toward ideas. In the 1950s, Greenspan fell in with Ayn Rand’s inner circle, “The Collective,” and contributed “Gold and Economic Freedom” to her 1966 anthology Capitalism: The Unknown Ideal. The essay was a full-throated defense of the gold standard — hard money, let markets discipline themselves. The joke writes itself: the gold-standard ideologue would later, as Fed Chairman, preside over the greatest era of fiat-money expansion in history. He was a libertarian who discovered that crises turn theory into ash.

He arrived at the Fed in 1987, appointed by Reagan, and stayed through four presidencies until 2006. Along the way he weaponized opacity. His speeches were famously impenetrable — a rhetorical fog dubbed “Greenspeak.” He once quipped, “If I seem unduly clear to you, you must have misunderstood what I said.” As economists Blinder and Reis later put it, “The secret to Greenspan’s success remains a secret.”

Behind the marble facade, though, was warmth. In 1997 he married NBC’s Andrea Mitchell, in a ceremony officiated by Ruth Bader Ginsburg. Mitchell’s verdict on his proposal style: “He claims he proposed three times before I was able to understand. He was so oblique.” The man who spoke in riddles to Congress could not even pop the question in plain English.

The phrase that defines his legacy landed on December 5, 1996. At the American Enterprise Institute, Greenspan asked, “How do we know when irrational exuberance has unduly escalated asset values?” The Tokyo Nikkei dropped 3 percent before U.S. traders finished their coffee. He spent a decade trying to walk it back, but the words had escaped his control.

What he meant was that markets can lose their minds. What he built was more complicated. The “Greenspan put” — the market’s faith that the Fed would always ride to the rescue — became his signature. Every crisis drew rate cuts and liquidity. It worked until it didn’t. The moral hazard he incubated — privatize gains, socialize losses — laid the groundwork for 2008.

Then came the reckoning. On October 23, 2008, before Henry Waxman’s committee, Greenspan confessed: “I found a flaw in the model that I perceived is the critical functioning structure that defines how the world works.” Pressed further: “I made a mistake in presuming that the self-interest of organizations, specifically banks and others, were such that they were best capable of protecting their own shareholders.” The oracle had offered something more valuable than prophecy: humility.

Greenspan died on June 22, 2026, at age 100, from complications of Parkinson’s disease. Mitchell’s statement was characteristically elegant: “He had ‘irrational exuberance’ for baseball, the Washington Commanders, tennis, golf and music, especially jazz.” Even in death, the phrase followed him.

To read his legacy in June 2026 is to watch a mind evolve in public — ideologue to pragmatist, oracle to penitent. He was not always right. He was rarely clear. But he was the man who knew more about the American economy than anyone alive, and who had the honesty to admit what he did not. That honesty is why his voice still echoes through every market decision made today.
