U.S. stock index futures edged higher on Wednesday ahead of the Federal Reserve's monetary policy decision, while the Israel-Iran conflict entered its sixth day, with new missile strikes launched from both sides.

With the US markets on pause for the holiday and no major economic data scheduled, attention remains fixed on the Middle East situation and the global central bank response.

The headline event for the day will likely arrive at 2 p.m. Eastern, when the Federal Reserve is set to announce its latest move on interest rates. The nearly unanimous expectation is that it will hold rates steady, as it’s been doing for all of this year after cutting through the end of 2024.
