Kevin Warsh wants to reshape the Federal Reserve, but markets remain skeptical

The new Federal Reserve Chair, Kevin Warsh, has made it clear that he wants to change the way monetary policy operates. With inflation running above the 2% target for five consecutive years and the president who appointed him persistently criticizing the institution, this intention has its logic. However, financial markets are responding cautiously. Why is that? And what are the prospects for success?

In his two months in office, Warsh has mainly focused on three areas: the Fed's communication style, modernizing its data infrastructure, and the models used to interpret that data. The foundation of a "relatively silent" approach in communications is flawed and should be adjusted as soon as possible; his criticisms of the data and models are more substantial. However, what could truly determine the success or failure of his term is an issue that has received little attention so far—the ongoing U.S. fiscal deficit.

Communication: The Limits of Silence

Warsh has repeatedly emphasized that the market should "play the game, not the referee," meaning the Fed should talk less about its intentions, forcing the market to focus on fundamentals like growth and inflation. The problem is that, when it comes to interest rates, the fundamentals are the Fed itself.

Overnight rates are directly controlled by the Fed, while medium-term rates largely reflect the expected average for short-term rates. Investors can replicate long-term rates by rolling over short-term Treasuries, so long-term rates are closely linked to expectations for Fed policy. If the market is worried about future inflation, long-term rates will immediately rise to compensate for purchasing power risk.

The bond market is uneasy about Warsh's reluctance to discuss the future path of interest rates. After last week's press conference, where short-term rates were kept unchanged, long-term yields rose, reflecting this doubt: if inflation needs to be lowered, will the Fed actually act? Resolving these concerns doesn't require committing to specific rate paths but rather clearly stating what economic conditions would prompt an adjustment in rates.

Data and Models: The Criticism Is Justified

Warsh rightly points out that the current U.S. data system relies on surveys with declining response rates, lacking timeliness and precision. The economics community is already working on improvements, such as the Economic Measurement Institute to be established by the National Bureau of Economic Research in 2025, aiming to use 21st century information technology to measure the economy more effectively. In practice, this means greater use of anonymous transaction, payroll, and other administrative data for more detailed and timely analysis. Fed economists are already deeply involved. If these efforts receive the Chair’s support, it would be a positive step forward.

As for inflation models, Warsh’s call to re-evaluate previously used frameworks is also reasonable. Researchers have been looking into factors such as the frequency of corporate price adjustments, capacity constraints, cost drivers, supply chains, and the role of supply shocks and expectations. The experience of the past five years shows that reality is much more complex than any single model, and a healthy debate is more valuable in itself.

The Real Key: The Constraint of the Fiscal Deficit

An issue that has yet to become the direct focus of working groups, but may be most critical, is the interaction between monetary policy, fiscal deficits, and inflation. The extreme view holds that budget deficits are the ultimate source of inflation, with the gap eventually needing to be filled by central bank money-printing. Even if Congress ultimately addresses long-term deficits, accumulated debt could still constrain the Fed’s room for maneuver by increasing the fiscal cost of higher rates.

This conflict between monetary and fiscal policy was at the core of the post–World War II debate over the Fed’s independence. For Warsh to succeed, he will need to draw on the latest research and demonstrate political skill, winning cooperation from Congress in order to truly achieve the Fed’s objectives.
