Investing.com - The dollar pushed higher against a currency basket on Wednesday after hitting a one-month low overnight, but gains were held in check amid uncertainty over the U.S. trade situation.
The U.S. dollar index, which measures the greenback’s strength against a basket of six major currencies, was up 0.13% to 94.75 by 03:10 AM ET (07:10 GMT), pulling away from an overnight low of 94.34, which was the weakest level since August 1.

Sterling was a touch lower against the firmer dollar, with GBP/USD slipping 0.11% to 1.2858.
