Federal Reserve officials remained concerned about stubborn inflation at their September meeting, with most policymakers saying another interest-rate increase would likely be appropriate before the end of the year.

The Fed unanimously raised its benchmark rate by 25 basis points in September to a range of 3.75% to 4.00%, its first increase since 2023.

The minutes showed officials believed inflation risks remained tilted to the upside, while the labor market was broadly stable and close to maximum employment.

Several policymakers said interest rates were still only mildly restrictive — or potentially not restrictive at all — suggesting the Fed believes monetary policy may still need to tighten further.

Officials pointed to higher energy prices, tariff effects and strong AI-related investment as sources of inflation pressure. Some policymakers warned that the scale of the AI buildout could push demand ahead of supply and keep prices elevated.

At the same time, officials generally viewed the economy as solid. Consumer spending remained resilient, business investment was strong and financial conditions were still considered supportive despite the sharp rise in longer-term Treasury yields.

The minutes also showed officials discussing Treasury-market stability. Policymakers said markets were functioning smoothly but argued the Fed should be prepared for periods of market stress while avoiding an unnecessarily large footprint in government bond markets.

The key takeaway is that the Fed has not declared victory on inflation.

Most officials still expect one more rate increase this year, but future decisions remain dependent on incoming data.
