S&P 500 Reacts To Fed's Game Of Keep Away With December 2025 Rate Cut

The S&P 500 (Index: SPX) set a new record high of 6,890.89 on Tuesday, 28 October 2025 following a new trade truce between the U.S. and China over the weekend and big deals and earnings among AI companies on Tuesday. Unfortunately, that new record high came the day before the Fed cut U.S. interest rates and Federal Reserve Chair Jerome Powell said some things that upset investor expectations. The index went into retreat, ending the week at 6,840.20, up just 0.7% from the previous week's close.

After the Fed reduced the Federal Funds Rate by a quarter percent to a target range of 3.75-4.00%, the CME Group's FedWatch Tool projects one more quarter point cut to this base interest rate in 2025. That rate cut is still expected on 10 December (2025-Q4), even though Fed Chair Jerome Powell tried to cast doubt on whether the Fed will follow through with another interest rate reduction before the end of the year. The FedWatch tool captured that change in expectation by lowering the probability of a December rate cut from more than 90% to 63%.

In 2026, the FedWatch tool anticipates better than 50% probabilities for quarter point rate cuts on 29 April (2026-Q2) and 16 September (2026-Q3), though the potential timing of these rate cuts has become very fluid in response to Fed Chair Powell's comments.

The net effect of Powell's statements has been to keep investors focused on the current quarter of 2025-Q4 in setting current day stock prices. The latest update of the alternative futures chart shows the S&P 500's trajectory pacing the projection associated with investors focusing their forward-looking attention on 2025-Q4.

That's not much different than the projection for 2026-Q3, but the context provided by the market-moving headlines that communicate the now open question of whether the Fed will act to cut rates again in December 2025 sets the expectations associated with 2025-Q4 as predominant.

Despite many economic data reports remaining on hold because of the Senate Democrats' ongoing refusal to fund government operations, the Atlanta Fed's GDPNow tool's projection of real GDP growth in the U.S. during the recently ended 2025-Q3 ticked up to +3.9% because of positive existing home sales data, which comes from private sector sources. The BEA's first official estimate of GDP for 2025-Q3 however remains on hold.
