Federal Reserve Chair Jerome Powell signaled openness to interest rate cuts starting as soon as September, sending Treasury yields lower and lifting equities. Speaking at the Jackson Hole Economic Symposium, Powell stated that "the time has come" to adjust policy if inflation continues its downward trajectory.

The remarks marked a shift from the Fed's prior hawkish stance. Inflation readings have cooled from their 2022 peaks, with the personal consumption expenditures price index now closer to the Fed's 2% target. Powell acknowledged that the central bank has made "substantial progress" on its inflation mandate while noting persistent labor market strength.

Markets immediately repriced expectations. The 10-year Treasury yield dropped roughly 20 basis points following Powell's comments, reflecting investor confidence in near-term rate reductions. Stock futures surged, with the S&P 500 and Nasdaq 100 pointing to significant gains at the open. Tech stocks, which suffer from higher borrowing costs when rates climb, showed particular strength in after-hours trading.

The Fed has held rates in the 5.25% to 5.50% range since July 2023. A September cut would mark the first reduction since March 2020, when the pandemic forced emergency policy shifts. Market participants now price in a 75% probability of a 25-basis-point cut at the September Fed meeting, up sharply from prior estimates.

Powell emphasized that any rate adjustment hinges on continued disinflation and stable economic conditions. He avoided committing to a specific cut magnitude or timeline, maintaining flexibility. The Fed chair noted that labor market slack has increased modestly, with unemployment ticking higher, supporting the case for easier policy.

Asset managers and traders face near-term volatility as markets digest the pivot. A September cut boosts refinancing conditions for borrowers and reduces equity risk premiums, but extended cuts could spark renewed inflation concerns if the economy proves more resilient than expected.

Investors should monitor the August jobs report and the core PCE inflation reading due before the September FOMC meeting for signs of whether the Fed follows through on rate cuts.
