Warsh channels Greenspan's playbook, ending 2 decades of Fed guidance

Fed Chair Kevin Warsh has adopted Alan Greenspan's "strategic ambiguity" as his policy template, refusing to offer forward guidance or publish rate projections at his June 17 debut meeting, a break from two decades of Fed communication orthodoxy.

"Warsh is consciously channeling the Greenspan era — data-dependent, deliberately opaque on the path ahead, and skeptical that low unemployment must come at the cost of higher inflation," Barron's wrote in a commentary following the press conference. The Financial Times separately warned Warsh against embracing the "Greenspan put" — the market perception that the Fed will backstop equity declines.

Greenspan, who died this week at age 100, chaired the Fed from 1987 to 2006, a period in which the S&P 500 gained 290 percent. His hallmark was a refusal to telegraph policy moves, forcing markets to react directly to economic data rather than to the central bank's own forecasts. Warsh's first policy statement contained no forward guidance, and he declined to submit the quarterly "dot plot" of individual rate projections that his predecessors had used since 2012.

The shift carries high stakes for markets. Warsh has rejected the traditional "cruel trade-off" between employment and inflation, arguing that productivity-driven growth can keep both in check. First-quarter 2026 productivity growth hit 2.8 percent, well above the post-financial-crisis average of about 1.4 percent and reminiscent of the late-1990s technology boom when Greenspan presided over a similar expansion.

The Productivity Bet

Warsh's policy philosophy rests on a supply-side logic that Greenspan championed in the 1990s: structural gains from technology and efficiency can lift potential output without stoking inflation. In his June 17 press conference, Warsh said low unemployment and solid growth need not come at the expense of price stability — a direct echo of Greenspan's congressional testimony from that era, when he argued that the Phillips Curve had broken down.

The approach has drawn comparisons to Greenspan's use of real-time market prices — commodities, gold, the yield curve — as policy anchors rather than rigid inflation targets. Warsh, who has long advocated for more rule-based policy, is expected to adopt a similar framework, though he has not specified which indicators he will prioritize.

The Greenspan Put Problem

The most contentious part of Greenspan's legacy is the so-called "Greenspan put" — the belief that the Fed will cut rates to rescue falling equity markets. That perception persisted long after Greenspan left office and has resurfaced as Warsh takes the helm with markets already pricing in a supportive Fed.

The Financial Times urged Warsh to dispel the notion early. "He should not hold a dogmatic position on market issues, nor should he be seduced by the golden calf of Wall Street and Silicon Valley," the newspaper wrote. The risk is that if markets believe the Fed will backstop losses, excessive risk-taking could inflate asset bubbles — the same dynamic that Greenspan's low-rate policy helped create before the 2008 financial crisis.

Greenspan's free-market ideology, while celebrated during his tenure, also drew criticism for blinding the Fed to the buildup of unstable credit conditions. International清算银行 adviser William White had warned of the risks years before the global financial crisis materialized.

For Warsh, the challenge is to replicate Greenspan's data-driven flexibility while avoiding the moral hazard that accompanied it. The next Fed meeting is scheduled for late July, and markets will be watching closely for any sign of whether Warsh's strategic ambiguity extends to the policy rate itself.
