The Fed's Preferred Inflation Metric Came in Cooler Than Expected. Here's What That Means for Interest Rates This Year

The August PCE inflation index held at 3.4%, matching July's reading and coming in below market expectations. The Federal Reserve's preferred inflation gauge triggered an immediate repricing in rate-hike probabilities: odds of an October increase dropped from 70% to 37% following the release.

Equity markets posted modest gains on the cooler-than-expected inflation print. The unchanged month-over-month reading suggests price pressures may be stabilizing after months of persistent elevation, though the 3.4% figure remains well above the Fed's 2% target.

The sharp decline in October rate-hike expectations reflects trader reassessment of the central bank's next move. With inflation no longer accelerating, the Fed gains flexibility to pause its tightening campaign. However, the market is tracking multiple data streams before the next Federal Open Market Committee decision.
