Federal Reserve’s Musalem warns against betting on AI to fix inflation

St. Louis Fed President Alberto Musalem has been making the rounds with a pointed message for markets and fellow policymakers alike. AI investments have been great for boosting demand, think data centers and soaring tech equity valuations, but the supply-side productivity miracle that’s supposed to bring prices down? Still waiting on that one.

The demand side showed up, the supply side didn’t

Musalem’s argument is straightforward. AI has generated enormous economic activity on the demand side. Companies are pouring capital into infrastructure, chips, and compute power. What it hasn’t done, at least not yet, is deliver the kind of broad-based productivity improvements that would push costs down across the economy.

During an April 1, 2026 event at the American Enterprise Institute, Musalem drew a clear line between these two dynamics. The investment boom is real. The disinflationary payoff is theoretical.

Core PCE inflation, the Fed’s preferred gauge, sat at 3.1% in January 2026. That’s well above the 2% target, and forecasts showed minimal improvement heading into February. Musalem has been blunt about what that means for the Fed’s posture.

“It’s too early to outsource our job of bringing inflation back towards 2%.”

That line, from a January 13, 2026 webcast, is about as close to a mic-drop moment as you get from a regional Fed president.

Productivity growth: decent but not extraordinary

Productivity growth over recent years has been roughly average when measured against post-World War II trends. Automation investments since 2022 have contributed to measurable gains, but not the kind of step-change that would justify rewriting the inflation playbook.

Fed minutes from earlier this year reflected this tension directly. Officials noted ongoing uncertainty about AI’s economic impacts, with mixed expectations about whether the technology would ultimately prove disinflationary.

What this means for investors

The practical takeaway is that rate cut expectations need a reality check. If the Fed isn’t willing to lean on AI productivity gains as a reason to ease policy, then inflation staying above target means rates stay higher for longer.

There’s also a second-order effect worth watching. AI investments have been a significant driver of equity wealth, which in turn supports consumer spending, which in turn keeps demand elevated. Musalem essentially identified this as part of the problem. The AI boom is feeding into demand-side inflation pressure even as it fails to deliver supply-side relief.

The broader message from Musalem is that monetary policy isn’t going to take a back seat to speculative optimism. For investors navigating this environment, the safest assumption is that the Fed will keep doing what it’s been doing: watching the data, not the demos.
