The dollar edged higher on Wednesday as investors awaited a closely watched Federal Reserve rate decision in what was likely ​to be Chair Jerome Powell’s swan song, against a backdrop of an Iran war that shows little sign of imminent resolution.

Activity was tempered by markets ‌in Japan closing for a public holiday and by caution ahead of a string of major central bank decisions over the coming 48 hours, along with the likes of Amazon, Microsoft and Meta reporting earnings after Wednesday’s closing bell.

Against the dollar, the euro dipped 0.07 percent to $1.1705 while sterling slipped 0.05 percent to $1.3513, as both currencies edged further away from their highs earlier this month.

The euro is around 1 percent below where ​it was at the end of February when the war broke out, while the pound is roughly unchanged.

The Fed’s rate decision will later take centre stage. The ​central bank is widely expected to keep rates on hold, leaving the focus on policymakers’ assessment of the war’s impact on the economy and on Powell’s future.
