Boston Federal Reserve President Susan Collins said the latest U.S. inflation readings do not yet warrant abandoning her expectation of gradual disinflation, despite a stronger-than-expected headline rate. Her comments at Jackson Hole underline the Federal Reserve’s continuing challenge of distinguishing persistent, broad-based inflation from price increases driven by narrower or temporary factors.

Headline Inflation Masks a Mixed Picture

The Personal Consumption Expenditures Price Index increased at a 3.7% annual rate in July, significantly above the Federal Reserve’s 2% target. The reading has prompted some Fed officials to argue that monetary policy may need to remain tighter for longer or potentially move toward higher rates.

Collins, however, emphasized the composition of the increase rather than relying solely on the headline figure. She pointed to portfolio management fees, which have risen alongside stock valuations, as one example of an inflation component influenced more by financial-market conditions than conventional supply-and-demand pressures. She said monthly inflation for market-priced goods and services was around the Fed’s 2% target, which she viewed as a more encouraging signal.

Productivity and Tariffs Could Support Disinflation

Collins said her modal scenario continues to involve gradual disinflation while the current policy rate remains slightly restrictive. Her assessment is based partly on Boston Fed research indicating that improving productivity could help reduce price pressures.

She also said inflation associated with tariffs imposed by the Trump administration may be nearing the end of its impact on prices. If that assessment proves correct, some of the forces that have kept inflation elevated could fade without requiring an additional monetary-policy response. At the same time, Collins stressed that a broad-based increase in market prices would be more concerning and that she remains willing to raise rates if inflation does not moderate as expected.

Bond Yields Remain a Key Signal for the Fed

Collins is also monitoring the recent rise in Treasury yields because borrowing costs across the economy are closely linked to financial-market conditions. So far, she said there was no evidence that the move reflected a deterioration in inflation expectations.

Measures of inflation compensation derived from inflation-protected securities remain, in her assessment, consistent with price stability. That distinction matters for policymakers because higher nominal yields can result from several factors, including expectations for growth, changes in the supply and demand for government debt, or inflation concerns. Collins said it remains difficult to identify precisely all the forces behind the broader increase in yields.

The next major signal could come from Federal Reserve Chair Kevin Warsh’s speech at Jackson Hole on Friday. His comments may provide additional guidance on how policymakers are interpreting the July inflation data and whether the balance of risks is shifting toward renewed monetary tightening. For global investors, the key issue is whether the Fed sees the latest price pressures as temporary and uneven or as evidence of a more persistent inflation problem. That distinction will influence expectations for U.S. interest rates, Treasury yields, the dollar and broader risk assets in the months ahead.
