The dollar index was off 0.03 to 90.30. The greenback was down to 115.61 yen. The Chinese central bank adviser Yu Yongding said further changes in the bank's yuan policy were inevitable, but changes would be gradual. Reuters reported that Yu's comments come at a time when the dollar failed to break a key option-related technical resistance of 116 yen, prompting traders to close their stale long positions.
The euro was little changed at $1.1944. The sterling was up a bit at $1.7686.
