Investors watch key inflation data ahead of Federal Reserve's rate decision

U.S. investors are focused on upcoming producer- and consumer-price data that could influence whether the Federal Reserve raises interest rates at its September 15–16 meeting. The consumer price index report due September 11 is viewed as the key test of whether inflation is cooling enough for policymakers to hold rates steady. Stocks are on track for a second consecutive weekly gain, with the S&P 500 near its mid-August record high as easing Treasury yields support the rally. The index has risen more than 13% in 2026 on strong corporate profits, although investors remain alert to September’s historically weak seasonal performance, bond-market volatility and renewed Middle East tensions.
