Former Federal Reserve Chairman Alan Greenspan passed away at age 100 this past week, just on the heels of the arrival of the central bank's new leader, Kevin Warsh. It is an opportune time to assess whether Chairman Warsh's tenure will resemble Greenspan's. After all, Warsh mentioned Greenspan numerous times during his swearing-in ceremony and promoted Greenspan's ideology during his first Fed press conference on June 17, effectively positioning the former chairman as his role model for how to conduct monetary policy.
Greenspan was at the helm of the Fed from 1987 to 2006, an era encompassing many events that profoundly impacted markets, including the 1987 stock market crash, the 1994 Mexican peso crisis, the 1998 failure of Long-Term Capital Management, the 2000 bursting of the dot-com bubble, and major corporate scandals of 2001 and 2002. Here's to the Warsh era being less dramatic.
Throughout his tenure, Greenspan displayed the deftness, nimbleness, and flexibility that earned him the moniker "Maestro." His term produced a prosperous economy with above-trend growth, strong employment gains, and price stability. Growth-oriented initiatives on the fiscal, trade, and regulatory fronts also contributed to this record. Surely, he ranks as one of the Fed's great leaders.
Similarities between his monetary philosophies on issues like forward guidance, rules-based policymaking, the Phillips curve, and productivity growth driven by high-tech innovation and Warsh's are now emerging. The Greenspan Fed never issued the extensive and long-term forward guidance that later became so prevalent at the central bank. Indeed, the Maestro was famous for being deliberately ambiguous to keep the financial markets guessing. Call it strategic ambiguity.
Warsh is clearly embracing this concept. The statement released at the conclusion of the Fed's June policy meeting gave no forward guidance, and Warsh declined to issue a dot for the so-called dot plot of Fed officials' quarterly economic and interest rate forecasts. Warsh plainly stated that he would prefer markets to react to economic data directly, rather than have it flow through the filters and forecasts of various Fed governors.
In concert with Fed Governors Wayne Angell and Manuel Johnson, Greenspan adopted a more rules-based approach to policy, with real-world market prices influencing decision-making. The Fed studied prices for a variety of industrial and agricultural commodities, the yield curve, the foreign-exchange value of the dollar, and gold to gauge whether policy was accommodative or restrictive.
Warsh likely will incorporate some of these principles. He has consistently argued that policy should be more rules-based and less arbitrary.
Greenspan is most well-known for his 1996 speech in which he mused about irrational exuberance in the financial markets. Less publicity has been given to his observations regarding the Phillips curve, which posits a trade-off between inflation and unemployment. But those, too, were crucial to his policy formulation.
In many of his speeches and congressional testimonies during the latter half of the 1990s, Greenspan argued that structural shifts in the economy, particularly concerning productivity, had rendered the Phillips- curve theory moot. He rejected the notion that the trade-off was driven by overheating demand. Instead, he focused on the supply side of the economy, anchored by robust productivity growth and capacity expansion.
Warsh has made clear that he also believes low inflation, strong economic growth, and low unemployment can coexist peacefully. At his June press conference, he rejected the concept of a "cruel choice" between inflation and employment. He was adamant that with proper monetary policy, low unemployment and robust economic growth don't have to lead to higher inflation. This is a refreshing change from the dogma of the past several years. It means that good news can be treated as good news.
Similarly to Greenspan in the 1990s, Warsh has focused on structural drivers of the economy, such as profound technological changes and productivity growth.
The productivity story is of particular importance because it serves as a silver bullet for economic well-being and prosperity, enabling higher real wage growth while reducing inflationary pressures. Until recently, the U.S. had been in a secular slump on this front, with growth rates of around 1.4% since the 2008-09 financial crisis. Data from the past couple of years suggest we may be in the early stages of a significant ramp-up in productivity growth, driven by a capital spending boom. This is reflected in the year-over-year productivity growth rate of the first quarter of 2026, which rose to 2.8%.
There are parallels here to the late 1990s, when tech innovation and investment resulted in productivity increases routinely north of 2.5%. That is important to investors because, historically, vibrant increases in productivity align with robust stock market returns.
Warsh has articulated an unwavering commitment to restoring price stability. History shows this achievement would produce widespread economic and financial benefits. Let's hope that the Warsh era can match or surpass the 290% increase that the S&P 500 generated during the Maestro's tenure.
