Federal Reserve officials are widely expected to leave their key interest rate unchanged on Wednesday, keeping it at the two-decade high of 5.3 percent for a 12th straight month in a bid to slow economic growth and crush inflation.

But investors will be most focused on what comes next for borrowing costs. Economists and traders widely expect Fed officials to cut their policy rate at their next meeting, in September. Wall Street will closely watch for any hints about the future in both the Fed’s statement at 2 p.m. and a subsequent news conference with Jerome H. Powell, the chair of the central bank.

While few economists expect an explicit signal on when a rate reduction is coming — the Fed has been trying to keep its options open — many think that central bankers will at least leave the door open to a cut at the next meeting, which will wrap up on Sept. 18. And Mr. Powell is sure to face questions about how officials are thinking about the potential for moves after that. Here’s what to look out for.

The Fed’s statement, a slowly changing document that officials release after each two-day meeting, currently states that Fed policymakers expect to hold rates steady until they have “gained greater confidence that inflation is moving sustainably” down.

Michael Feroli, chief U.S. economist at J.P. Morgan, wrote in his preview note that the statement could be headed for a small but meaningful tweak: Officials could adjust “greater confidence” to read “further confidence,” or some similar rewording. That would signal that policymakers were becoming more comfortable with the inflation backdrop.

There would be a reason for that growing confidence. After proving surprisingly stubborn early in 2024, inflation is cooling again. The latest report showed that the Fed’s preferred index picked up just 2.5 percent over the year through June — still quicker than the central bank’s 2 percent target, but much slower than that measure’s recent peak in 2022, which was above 7 percent.
