USD rose against other major currencies in the European session on Wednesday as lingering worries about the impact of rising coronavirus infections on global economic recovery continued to fuel demand for the safe-haven dollar.

The U.S. Dollar Index (DXY), measuring the U.S. currency's value relative to a basket of foreign currencies, edged up 0.10% to 93.06.

Driven by the Delta variant, COVID-19 cases continued to climb across the world. South Korea and Thailand reported record infections. The chief of the Japanese government’s anti-virus task force warned that new cases in the country could top the peak of the third infection wave in early August, before the end of the Olympic Games in Tokyo.

Investors are worried that growing infections would trigger the imposition of new strict restrictions that could hurt the global economic recovery.
