Fed Chair Kevin Warsh Has an Inflation Conundrum, and Trumpflation Is Only Part of the Problem

During Fed Chair Kevin Warsh's swearing-in ceremony at the White House on May 22, he vowed to lead a reform-oriented central bank.

Through his first four months at the helm, we've witnessed sizable changes at the Federal Reserve and added uncertainty for Wall Street's major stock indexes, the Dow Jones Industrial Average (DJINDICES:^DJI), S&P 500 (SNPINDEX:^GSPC), and Nasdaq Composite (NASDAQINDEX:^IXIC). These reforms include (but aren't limited to):

• The removal of forward-looking guidance from Federal Open Market Committee (FOMC) meeting statements.
• The commissioning of five task forces to aid the Fed's conduct of monetary policy.
• A shift in the FOMC's policy approach by declaring price stability the more important of the two components of the dual mandate (maximum employment and price stability).

Warsh has also kicked off only the fourth rate-hiking cycle of the 21st century. He and the 11 other voting FOMC members unanimously raised interest rates by 25 basis points to 3.75%-4.00% on Sept. 16. With inflation persistently elevated above the Fed's 2% long-term target for 66 consecutive months (and counting), action was warranted.

But the complex nature of the inflationary pressures the FOMC is fighting creates quite a conundrum for the new Fed chair. Though Trumpflation (i.e., inflation directly related to President Donald Trump's policies) is part of the problem, it's not the only reason inflation is persistently elevated. If Warsh tackles the heart of the issue, it could upend the stock market's historic rally.

Fed rate hikes are tackling Trumpflation head-on

Though modest inflation is perfectly normal in a growing economy, two of President Trump's policies are responsible for boosting the prevailing inflation rate in 2026.

To begin with, the president's tariff and trade policy is affecting consumer prices. We witnessed this happen last year, shortly after Trump unveiled his "Liberation Day" tariffs on April 2, 2025. The Liberation Day tariffs imposed sweeping global duties, along with higher reciprocal rates, on dozens of countries.

Core CPI inflation falls to 2.4%, also in-line with expectations of 2.4%.

Month-over-month CPI inflation rose +0.4%, the biggest increase since May 2026.

Treasury yields are rising on the news.

Although the U.S. Supreme Court invalidated these Liberation Day tariffs in February 2026, the Trump administration reinstated global tariffs, ranging from 10% to 12.5%, on over 80 countries in late July. Placing duties on unfinished imported goods can increase domestic production costs and lift consumer prices.

The other component of Trumpflation is the Iran war.

Not long after President Trump approved military action against Iran on Feb. 28, the latter closed the Strait of Hormuz to most commercial vessels. This is a critical global chokepoint for crude oil transport, and its ongoing closure has sent fuel prices soaring.

But Trumpflation isn't just limited to the energy sector. Higher prices for petroleum-based products (e.g., plastics), altered shipping routes, and supply-chain adjustments are just some of the added expenses businesses are contending with that are likely being passed on to consumers.

To deliver price stability, the Fed had little choice but to undertake a rate-hiking cycle.

AI-driven inflation is a major monkey wrench for Fed Chair Warsh and the FOMC

However, persistently elevated inflation isn't being caused solely by Trumpflation -- and that's a problem for Fed Chair Warsh and his colleagues.

Beginning with the June FOMC meeting, policymakers homed in on the artificial intelligence (AI) infrastructure build-out as another key driver of consumer prices.

On the one hand, the AI revolution has been invaluable to Wall Street. The historic spending by businesses on graphics processing units (GPUs), high-bandwidth memory (HBM), rack servers, and storage solutions has pushed up corporate growth rates and almost single-handedly lifted the Dow Jones Industrial Average, S&P 500, and Nasdaq Composite to record highs this year.

In addition to exceptionally strong demand for AI hardware, businesses are benefiting from never-before-seen pricing power, courtesy of persistent supply shortages. Even with contract chip manufacturers expanding their output at a breakneck pace, there simply aren't enough GPUs, HBMs, rack servers, and storage solutions to satiate enterprise demand.

While AI companies and investors are thrilled with this newfound pricing power, it's terrible news for consumers. These higher costs have worked their way downstream, increasing consumer prices and contributing to persistently elevated inflation. Although AI is expected to increase economic output over the long-term, it'll likely take years for this technology to become disinflationary.

Fed now officially blaming AI for rise in core inflation:

"Core goods price inflation had risen relative to a year earlier, which the staff judged as largely reflecting the effects of tariffs and AI-related price pressures"

Here's where the conundrum comes into play for Fed Chair Warsh: raising interest rates to deliver price stability can adversely impact the U.S. economy's and stock market's No. 1 growth catalyst.

The otherworldly spending we've witnessed on the AI data center build-out has been partially driven by debt. If the FOMC continues to raise borrowing costs, it threatens to slow AI infrastructure purchases. If that happens, we may witness a broad-based re-rating of premium stock valuations.

Furthermore, Fed Chair Warsh noted in his comments to the press on Sept. 16 that one of the reasons long-duration bond yields have risen so robustly is the "competition for capital." More specifically, he highlighted AI hyperscalers' capital-raising efforts as a source of higher long-duration Treasury yields. Significantly higher 10- and 30-year bond yields point to the need for further action by the FOMC.

If Warsh and his colleagues don't act, the AI revolution continues unhindered... and so does persistently elevated inflation. But if the FOMC follows its initial quarter-point rate hike with several additional increases to quell inflation, it may mark the end of the parabolic AI bull market on Wall Street and tilt the U.S. economy into a recession.
