Softer August inflation print knocks October Fed hike odds below a coin flip

The Federal Reserve’s preferred measure of inflation dipped to 3.4 percent in August¹, and core inflation came in at 3 percent, below forecasts⁴. US inflation rose by less than expected over the month while consumer spending stayed robust⁹.

Consumer spending rose at its fastest rate in a year during August as households kept spending despite higher fuel prices and interest costs⁵. The Bureau of Economic Analysis also revised second-quarter GDP growth to an annual rate of 2.2 percent alongside the inflation release⁴.

Investors cut their bets on an October rate increase³. Pricing for an October hike had dropped to just below 50 percent after soft consumer sentiment and JOLTS data the previous day⁶, from more than 70 percent earlier in the week³.

Why it matters to investors

The debate inside the Fed is about the timing of the next increase, not a cut. New York Fed President John Williams said he saw no urgency for the next rate hike^7,9, and his comments cast additional doubt on when a further rise would come². The Financial Times reported that the weak inflation print eased pressure for Fed rate increases².

Williams did not rule out further tightening. He noted that one further upward adjustment remained in view¹, which leaves the direction of travel intact even as the date slips.

Governor Michael Barr took the other side, saying more rate hikes are likely to be needed to curb inflation⁸. The two positions together explain why market pricing has become unstable rather than settling on a single path.

What to watch

The data calendar is now the deciding factor. One analysis described the October hike as remaining very data dependent⁶, and the pullback in pricing followed Williams’s remarks rather than the inflation figure alone^3,9.

The tension between the two halves of the report is the thing to track. Inflation is easing on the Fed’s preferred gauge^1,4 while spending is accelerating⁵ and second-quarter growth was revised higher⁴. A consumer that keeps spending through higher fuel costs⁵ argues for more tightening on Barr’s reading⁸; a cooling price gauge argues for patience on Williams’s⁷.

For portfolios, the near-term question is whether October pricing stabilises around the sub-50 percent level⁶ or swings back toward the levels seen earlier in the week³.
