US PCE Inflation Sticks at 3.7%, Boosting Fed Rate Hike Odds Ahead of Jackson Hole

The hotter-than-expected US Personal Consumption Expenditures price index for July has reignited speculation that the Federal Reserve may need to deliver at least one more rate increase before the end of 2026.

Headline inflation held at 3.7% year-over-year while the core measure showed persistence, with the monthly advance exceeding forecasts.

This comes as second-quarter GDP growth was left unrevised at a modest 1.5%, underscoring that the economy is not overheating but inflation remains sticky enough to keep policymakers vigilant.

Traders have responded by lifting the implied probability of a September or December hike, sending the dollar higher and Treasury yields modestly firmer.

The data lands just days before the Jackson Hole symposium, where incoming Fed Chair Kevin Warsh is expected to deliver the keynote address that could clarify the central bank’s reaction function.

Markets are now focused on whether Warsh signals tolerance for current inflation levels or leans toward further tightening to avoid an abrupt adjustment later.

Sectors most directly affected include interest-rate-sensitive areas such as housing, autos, and growth stocks, which have already seen volatility on the mixed signals.

Fixed-income investors are watching 10-year yields for any sustained break above recent ranges, while currency traders eye EUR/USD and USD/JPY for confirmation of a hawkish repricing.

Next catalysts include Warsh’s speech, upcoming labor-market data, and any follow-up comments from other FOMC members. A dovish tone at Jackson Hole could quickly reverse the recent dollar gains, whereas a firm stance would likely extend the sell-off in long-duration assets.
