U.S. stock index futures climbed Sunday evening, suggesting a firmer start for Wall Street as investors prepared for a busy week of economic signals. Traders are watching closely for fresh clues on the Federal Reserve’s next moves, with rate expectations still driving sentiment across markets.

The gains came as markets braced for new inflation data that could shape the central bank’s policy path in the months ahead. Any surprise in the numbers could influence whether officials keep rates unchanged, cut them sooner, or maintain a more cautious stance.

Investors have been weighing mixed signals from recent economic reports, with the market still sensitive to any shift in the inflation outlook. That has kept attention fixed on both the Fed and incoming price data, which are expected to help define the tone for equities this week.

If the data confirms a gradual cooling in inflation, analysts say it could support risk appetite and help extend the recent rebound in stocks. But a stronger reading could revive concerns about higher borrowing costs and limit near-term upside.
