The U.S. dollar held at a one-month high on Tuesday as traders weighed a slim but lingering chance of a rate hike at the Federal Reserve's upcoming meeting, even as falling oil prices eased some concerns over inflation.
The dollar index, which measures the greenback against a basket of currencies including the yen and the euro, edged up 0.03% to 101.55, with the euro down 0.01% at $1.1366. Against the Japanese yen, the dollar gained 0.05% to 163.82, while sterling eased 0.02% to $1.3284.
