TheU.S. dollar index DXY last stood at 106.20, having peaked at a 10-month high of 106.26 in the previous session, while the euro EURUSD languished near Tuesday's six-month low and last bought $1.0569. "The U.S. dollar is stickier to the upside than the downside," said Tina Teng, market analyst at CMC Markets. "It's (been) a shock for markets since last week because the Federal Reserve's rhetoric was more hawkish than expected ... I think it's more likely they will hike rates for one more time."
