Greenspan Playbook to Get a Replay under Warsh

When Kevin Warsh was sworn in as Federal Reserve chairman on May 22, he cited Alan Greenspan four times during his White House ceremony. It was more than homage — it was a declaration of intent. Greenspan, who died Monday at 100 from complications of Parkinson's disease, is now being positioned as the intellectual godfather of a new era at the Fed. Whether that's a promise or a warning depends on which part of the Greenspan legacy Warsh chooses to replay.

The comparison is not casual. Warsh has explicitly aligned himself with Greenspan's approach to central banking: a reluctance to over-communicate, a deep trust in financial markets to sort things out, and a conviction that the Fed should keep its role as narrow as possible. In his first policy statement last week, Warsh returned to a shorter format and stripped out explicit guidance about the future path of rates. In his opening press conference, he argued that markets work best when they react to data, not when they sit around trying to predict what the Fed will do next.

There's a lot to like in this philosophy if you're an investor who believes the Fed has become too chatty. The era of "forward guidance" — essentially telling markets what you plan to do before you do it — has its critics on both sides. Hawks say it ties policymakers' hands. Doves say it creates false certainty. Warsh's instinct to let markets process information on their own, rather than spoon-feeding them, has a certain intellectual elegance.

But the Greenspan playbook has a specific historical chapter that Warsh's admirers tend to skip over. Greenspan's deep faith in the wisdom of markets led him to downplay the housing bubble that was inflating right under his nose. As Brookings Institution Senior Fellow Donald Kohn — a top Fed staffer under Greenspan and eventual vice chair — wrote in his appreciation published Monday, Greenspan "doubted a national bubble across these markets, and he did little with his soapbox or powers over bank regulation to preemptively build resilience." The result was the worst financial crisis since the Great Depression.

Warsh now faces a parallel decision point. He's pushing to pare back the Fed's imprint, loosen regulations that grew out of the 2007-2009 crisis, and dial back the central bank's expanded communications apparatus. Fed Vice Chair for Supervision Michelle Bowman is already loosening post-crisis banking rules. The question isn't whether some of that regulation was excessive — it's whether the pendulum is swinging too far in the other direction at exactly the wrong moment.

Because here's what makes 2026 different from 1996: the economy Warsh inherits isn't enjoying a "Great Moderation." It's running 4.2% annual inflation, still processing the economic disruption from the Iran conflict, and watching AI-driven market concentration hit levels that Goldman Sachs researchers warn create "greater sensitivity to earnings disappointment and the increased probability of a disorderly market correction."

Warsh's instinct to let markets lead has intellectual merit. But Greenspan's blind spot wasn't his philosophy — it was his refusal to update that philosophy when evidence contradicted it. The housing bubble was visible, and he chose not to see it. If Warsh inherits that same confidence without the institutional guardrails that post-crisis reform put in place, the risk isn't theoretical.

There's an intriguing subplot: Warsh has assigned a task force to study whether AI-driven productivity gains could suppress inflation, much as Greenspan argued in the mid-1990s that rising productivity warranted holding off on rate hikes. If Warsh is right about AI productivity, he could be the Greenspan of the 2020s. If he's wrong, he could be the Greenspan of 2008. The data will decide, but only if the Fed chairman is willing to look at it honestly.

What This Means For You: Warsh's "less talk, more markets" approach means less predictability for your investments. Under Powell, the Fed telegraphed its moves well in advance — markets could price in rate changes months ahead. Under Warsh, expect more volatility around Fed meetings and less certainty about the path of rates. If you have adjustable-rate debt (mortgages, credit cards, business loans), the old playbook of "wait for the Fed signal" may not work anymore. Consider locking in fixed rates sooner rather than later. And if you're invested in the Magnificent Seven tech stocks driving market gains, remember that Greenspan-era deregulation preceded the last major correction — the lesson isn't that regulation is always good, but that removing guardrails during periods of market concentration is a bet that history doesn't always reward.
