The euro and commodity-linked currencies rose on Wednesday as optimism over U.S.-China trade negotiations improved investor sentiment and encouraged some selling of the dollar.
Expectations of more easing in China also supported markets, with Asian shares rallying and European stocks rising at the open.
The euro rose 0.2 percent to $1.1464 as increased demand for currencies deemed riskier knocked the dollar lower.
An unexpected fall in German industrial output for the third straight month had weighed on the euro on Tuesday. The drop underscored concern about a slowdown and the European Central Bank’s caution as it tries to wean the region off stimulus.
The dollar index traded down 0.2 percent at 95.753.
