The dollar index has fluctuated narrowly around the psychologically important 90 level, and was last at 90.137.
The euro rose to a one-week high at $1.2218 on Wednesday only to finish little changed, and was essentially flat at $1.2178 in Asia.
The yen traded at 109.62 per dollar, also little changed from Wednesday and near the middle of the 109.19-110.325 range of the past two weeks.
Deutsche Bank's Currency Volatility Index languished at its lowest level since February 2020.
It last traded little changed at $37,097.02, after rebounding from a three-week low of $31,025 hit on Tuesday when signs of institutional investor caution and regulatory attention drove selling.
