Jackson Hole Hawkishness Sparks Rate Hike Odds Surge to 57%

At the annual Jackson Hole Economic Policy Symposium in Wyoming on August 28, 2026, US Federal Reserve Chairman Kevin Warsh delivered the keynote address. His remarks focused on inflation and the interest rate outlook, sparking a fresh round of market interpretation.

Warsh emphasized that price stability remains the Fed's top priority as inflation continues to run above the 2% target. The latest data showed the US's July PCE rose 3.7% year-on-year, slightly above expectations, while core PCE held at 3.3%. Despite lingering inflation, Warsh portrayed a resilient picture of the US economy and pledged to keep a close watch on market internals and corporate earnings trends.

Markets reacted sharply to Warsh's speech, with investors broadly interpreting it as hawkish. Padhraic Garvey, America's regional head of research at ING, noted that 'he was keen not to provide forward guidance, but his words smacked of forward guidance; he was net hawkish.'

The market's response was immediate, with US stocks ending lower on Friday and bond markets reacting more sharply. Short-term Treasury yields moved substantially higher, and the market pricing for a September rate hike jumped to 57% according to CME FedWatch.
