The dollar held its overnight gains on Tuesday as concerns about unrest in China over COVID-19 restrictions dampened market sentiment, and as hawkish remarks from Federal Reserve officials gave the greenback an additional leg up.
Rising tensions in China over the country's stringent pandemic measures sent investors flocking to the safe-haven dollar, triggering a slide of more than 1% in the Aussie, kiwi and sterling overnight.
The euro, which surged to a five-month peak of $1.0497 overnight, later reversed those gains following a rebound in the U.S. dollar. It was last marginally lower at $1.0339.

Flash euro zone inflation figures for November are due on Wednesday, with economists polled by Reuters expecting inflation to come in at 10.4% year-on-year. Ahead of that, inflation numbers from Spain and Germany are expected later on Tuesday.
"The central bank commentary that we've had this week, including from Lagarde, has got the market on guard for the risk that the ECB is going to raise rates by 75 basis points at its December meeting rather than 50 basis points, which had been a strong consensus up until the last few days," said Ray Attrill, head of FX strategy at National Australia Bank (NAB).

Comments from Fed Chair Jerome Powell on Wednesday will be watched for any new signals on further tightening, with key U.S. jobs data for November due on Friday. The U.S. central bank is widely expected to hike rates by an additional 50 basis points when it meets on Dec. 13-14.
