The U.S. dollar moved higher and stayed close to a one-month peak as markets waited for the Federal Reserve’s latest interest-rate decision. Traders appeared cautious ahead of the announcement, with some analysts leaving room for the possibility of an unexpected rate increase.

The dollar’s strength reflected a broader focus on U.S. monetary policy and what the central bank may signal next. Even without a clear consensus on a hike, expectations around interest rates continued to support the U.S. currency going into the decision.

At the same time, renewed hostilities in the Middle East pushed oil prices higher, adding another layer of uncertainty for investors. Rising energy prices can complicate the inflation outlook, which is closely tied to how central banks, including the Fed, assess future policy moves.

With both geopolitics and monetary policy in focus, currency markets remained tightly driven by risk sentiment and interest-rate expectations. The combination of a firmer dollar, higher oil prices and anticipation around the Fed kept trading centered on the outlook for inflation and global growth.
