Powell warns Fed independence at risk as inflation surges to 4.2%

The end of Jerome Powell's tenure as Fed chair has opened a new front in the battle over US monetary policy, with inflation accelerating to 4.2% and political pressure on the central bank intensifying.

"The public would lose faith that the central bank will make decisions based only on what's best for all Americans," Powell said on May 31 while accepting the John F. Kennedy Profile in Courage Award, his first public remarks since stepping down as chair on May 15.

The transition comes as the Federal Open Market Committee confronts a rapidly deteriorating inflation picture. Trailing 12-month inflation stood at 2.4% in February but surged to 3.8% by April, and the Cleveland Fed's Inflation Nowcasting tool estimates it reached 4.18% in May — the fastest pace in over a year. The FOMC enacted six rate cuts from September 2024 through December 2025, bringing the target range to its current level of 3.50% to 3.75%. Markets now price a 60% probability of at least one rate hike before the end of 2026, according to CME FedWatch data, up from near zero at the start of the year. The 10-year Treasury yield stood at approximately 4.40% in late May.

The combination of a new chair, rising prices, and political interference threatens the institutional credibility that underpins the dollar's reserve currency status and the US bond market's role as a global safe haven. If the Fed is perceived to bow to political pressure, real interest rates could rise even as nominal policy rates fall, compressing equity multiples and raising the risk premium on long-duration assets. ING's currency research team warned that "were the Fed to be seen cutting rates inappropriately, we could see a run on the dollar."

The Iran War Supply Shock

The Iran conflict that began Feb. 28 has created the largest energy supply disruption in modern history. The closure of the Strait of Hormuz halted the movement of about 20 million barrels of petroleum liquids per day, representing roughly 20% of global demand. Gasoline prices have risen at the fastest clip in more than three decades, and the pass-through effects on transportation and production costs are still feeding into official inflation data.

New Fed Chair Kevin Warsh, who officially took the helm on May 22, inherits this environment with a well-documented hawkish bent. During his Senate confirmation hearing, Warsh criticized the Fed's 2021-2022 policy as "a terrible policy error," arguing that the central bank waited too long to raise rates. "Once you let inflation take hold in the economy, it's more expensive and harder to bring it down," he said. Warsh served on the Board of Governors from 2006 to 2011, where he opposed maintaining low rates and quantitative easing during the financial crisis. His appointment raised expectations of a push for lower rates, but the inflation surge has made rate cuts virtually impossible.

A Fragile Equilibrium

The last time the Fed faced a comparable inflation surge was in 2021-2022, when it kept the federal funds rate at 0% to 0.25% for too long before embarking on the most aggressive hiking cycle in four decades. The S&P 500 entered a bear market in 2022, falling 25% from peak to trough as the Fed raised rates by 525 basis points over 16 months. The current federal funds target range of 3.50% to 3.75% remains well above the 1% or lower that President Trump has repeatedly called for.

Powell, who remains on the Board of Governors through January 2028, used his award speech to draw a direct line between political interference and economic damage. "If any administration finds a way to remove Fed officials over policy differences, then future administrations will do so as well," he said. President Donald Trump had publicly called for lower rates throughout 2025 and pursued legal action against Fed Governor Lisa Cook for alleged mortgage fraud, according to reports.

The equity risk premium — the excess return investors demand for holding stocks over risk-free bonds — is currently near its lowest level on record, with the forward earnings yield on the S&P 500 and the 10-year Treasury yield at near-parity, according to Goldman Sachs. That equilibrium works as long as inflation stays contained and investor confidence in institutional stability remains high. Any development that raises the perceived probability of policy error would likely compress equity multiples in a way that earnings growth alone cannot offset.

The next FOMC meeting is scheduled for June 30. OIS markets currently assign virtually no probability to a rate cut in 2026, a stark reversal from the easing trajectory that investors had priced at the start of the year. The S&P 500, Dow Jones Industrial Average, and Nasdaq Composite have all closed at record levels in 2026, but the divergence between equity prices and the deteriorating macro backdrop is growing. Shorter-duration fixed income over longer duration is the most direct hedge if real yields rise and the yield curve steepens, while gold has historically performed well in environments where institutional confidence in monetary frameworks is under stress.
