Economic Wire: Waller says Fed shouldn’t ‘fight the last war’ on inflation

The Fed’s Real Warning Isn’t About Rates. It’s About Where Inflation Went Next.

According to CNBC, Fed Governor Christopher Waller is urging the Fed not to “fight the last war” on inflation, while simultaneously keeping rate hikes on the table. The headline sounds like a contradiction. It isn’t. And the distinction matters more than most people are treating it.

The “last war” framing is the key signal here. Waller is essentially saying the Fed got inflation partially right but may have been too focused on the easy culprits: tariff-driven energy prices, supply chain bottlenecks, the obvious stuff. Now inflation has spread into areas that don’t respond the same way to the same tools. That’s a different problem. It means the policy transmission mechanism, the process by which rate hikes actually cool prices, may be working more slowly or unevenly than the Fed’s models assumed.

This is where the productivity angle becomes critical. If inflation is broadening into services, wages, or shelter in ways that are driven by structural factors rather than demand spikes, rate hikes alone won’t resolve it cleanly. They’ll slow the economy without necessarily addressing the root cause. That’s the scenario that historically creates the most difficult environment for corporate margins: slower revenue growth combined with sticky input costs.

Historically, when the Fed signals that its prior framework may be insufficient and that further tightening remains live, fixed income markets tend to reprice quickly while equity markets take longer to digest the implications. The mild risk-on tilt in today’s sector rotation, with financials running nearly 4% ahead of the broader market, suggests investors are still leaning constructive. But financials often benefit from a higher-for-longer rate environment, so that rotation may be telling a more nuanced story than simple optimism.

Bottom Line: When a Fed governor warns against fighting the last war, the real question worth sitting with is: what is the current war, and do we have the right weapons for it?
