"That's why the dollar is vulnerable," said Tomoko Fujii, senior currency analyst at Bank of America in Tokyo, adding that markets were waiting for the Federal Reserves next rate setting meeting on January 31.
"That's the big event for the month. We expect two more rate hikes, but others are expecting only one," she said.
