Tokyo - The dollar slipped against the euro and yen on Wednesday as another retreat in oil prices hit sentiment.
Crude resumed its decline in Asia ahead of the release of data on US crude stockpiles and production, keeping alive concerns about demand and the strength of the global economy.
Oil is at multi-year lows in the face of indications a global crude supply glut will continue into next year.
"Risk sentiment is very much subject to crude oil prices," Hiroyuki Yamamuro, analyst at Ueda Harlow, said, told Bloomberg News.
In US trading, the dollar had been lifted by upbeat consumer confidence data that bolstered hopes for the world's top economy.
