Markets price in a 90% probability of a quarter-point rate hike as August inflation data reverses earlier forecasts.

Interest-rate futures indicate a 90% probability of a quarter-point increase in the federal funds rate. This expectation follows the release of August Consumer Price Index data that reversed prior forecasts. The Federal Reserve is scheduled to announce its decision at 2 p.m. ET Wednesday.

The anticipated move would lift the target range to 3.75% to 4.00%. This marks the first rate increase since July 2023 under Chair Kevin Warsh. Eighty-five percent of economists surveyed by Reuters now predict this action.

Inflation Data Drives Policy Shift

Consumer prices rose 0.4% in August after a 0.1% increase in July. Annual inflation stood at 3.4%, unchanged from the previous month. Core inflation, which excludes food and energy, climbed 0.3% compared to the expected 0.2%.

Gasoline prices contributed significantly to the monthly increase. The energy index rose 16.3% from a year earlier. Shelter costs increased 0.3% in August, up from 0.1% in July. These figures suggest underlying price pressures remain persistent.

Mortgage Rates Track Long-Term Yields

The Federal Reserve does not set mortgage rates directly. Mortgage pricing responds primarily to longer-term Treasury yields. It also reflects inflation expectations and demand for mortgage-backed securities.

A short-term rate hike does not produce an equal increase in 30-year mortgage rates. The bond market’s reaction to the Fed’s projections is the critical variable. Analysts cited by GN auto markets/bonds: treasury yields note that the Summary of Economic Projections will guide market sentiment more than the immediate decision.

Future Outlook Remains Uncertain

Nearly 53% of economists expect at least one additional rate increase by March. Financial markets currently price in several increases through July 2027. This indicates a prolonged period of higher borrowing costs.

The upcoming meeting includes an updated Summary of Economic Projections. This document outlines policymakers’ expectations for inflation, growth, and unemployment. The characterization of the inflation outlook by Chair Warsh will determine whether the long-term bond market stabilizes or remains unsettled.
