Core Inflation Cools to 2.26% — But the Monthly Print Tells a Different Story

Core consumer prices rose 0.21% in May, translating to an annualized pace of 2.5% — slightly above the Fed’s 2% target but well below the 3%+ monthly rates we saw through much of 2023 and early 2024. Year-over-year core inflation now sits at 2.26%, the lowest reading since early 2021.

Here’s the tension: while the annual comparison looks encouraging, that 0.21% monthly gain is actually the highest we’ve seen since February. Strip out the favorable base effects from a year ago, and the underlying momentum isn’t quite as clean as the headline suggests. We’re seeing what economists call “bumpy progress” — the general trend toward the Fed’s target remains intact, but it’s not a straight line down.

This matters enormously for monetary policy. The Fed has been looking for evidence that inflation is durably returning to target before considering rate cuts. A 2.26% annual rate checks that box, but three consecutive months of accelerating monthly gains (February: 0.16%, April: 0.20%, May: 0.21%) gives hawks ammunition to argue for patience. Corporate profit margins in services — where most core inflation originates — remain elevated, suggesting businesses still have pricing power.

In this environment, many professional investors focus on inflation-sensitive positioning. Historically, periods of “good enough but not great” inflation data have favored shorter-duration bonds over longer ones, and real assets over nominal ones. Value stocks often outperform growth when inflation expectations are anchored but not falling rapidly.

Bottom Line: Core inflation is moving in the right direction, but the monthly acceleration reminds us that the last mile to 2% is often the hardest. The Fed’s next move depends less on where we are and more on where this monthly trend heads next.
