The U.S. dollar edged higher in early European trade Wednesday, with the tone cautious given the event risk, including a central bank meeting and key U.S. unemployment data, later this week.

At 2:40 AM ET (0640 GMT), the U.S. Dollar Index, which tracks the greenback against a basket of six other currencies, stood at 99.925, up 0.2%, while EUR/USD fell 0.2% to 1.0822. GBP/USD edged lower to 1.2432 and USD/JPY fell 0.2% to 106.39.

The euro has seen selling, falling to a one-week low of $1.0817, after Tuesday’s decision by Germany's highest court to give the European Central Bank three months to justify purchases under its bond-buying program.
