U.S. stock futures climbed on Sunday night as investors positioned for a key speech by Federal Reserve Chair Jerome Powell at a European Central Bank forum on Monday. The move reflected growing market attention on the next signals from the Fed about interest rates and the broader outlook for inflation and growth.

Dow futures were up roughly 300 points, with traders also watching for direction in the S&P 500 and Nasdaq after a volatile stretch for equities. Powell’s comments are likely to be parsed closely for any shift in tone on how long borrowing costs may stay elevated.

Markets have been sensitive to any sign that the central bank could keep policy tighter for longer, especially as investors weigh economic data against the risk of slowing growth. Monday’s speech could help shape expectations for the weeks ahead.

The rally in futures suggests traders entered the new week in a cautious but optimistic mood, hoping for clarity from the Fed on the path of monetary policy.
