Fed Chair Kevin Wash will deliver his first Jackson Hole speech tonight, with the market watching for any policy signals for the September 15–16 meeting. Wash has previously committed to bringing inflation back to 2%, but has not indicated support for maintaining rates, raising them, or leaving room for cuts.

U.S. Bureau of Economic Analysis data shows that July PCE inflation rose by 3.7% YoY, core PCE rose by 3.3%, both significantly above the 2% target; real personal consumption expenditure did not increase, and personal income rose by 0.4% MoM. Inflation limits room for rate cuts, while cooling consumer spending and employment increase the economic cost of further hikes.

Officials have differing views. Kansas City Fed President Schmidt believes the current rate constraints are insufficient; Cleveland Fed President Hammack supports controlling inflation; Boston Fed President Collins expects inflation to gradually decline and currently does not support an immediate hike.

Three key points the market will focus on in tonight's speech: whether Wash directly discusses the September meeting; whether he sees the 3.7% PCE as a basis for further tightening; and whether he emphasizes cooling employment and supports a temporary wait-and-see approach. If he highlights inflation risk, the market may increase expectations of a hike or long-term maintenance of high rates; if he emphasizes slowing employment and spending, it may reinforce the judgment to maintain rates in September.

Before the rate decision meeting, the Fed will also receive the August jobs report and new inflation data. Wash may not necessarily provide a clear rate path, but his assessment of inflation persistence, employment risks, and policy constraints could alter the market's expectations for maintaining the 3.50%–3.75% rate range in September.
