While currency markets were generally calm, signs of nervousness were evident in the bond markets where yields on 10-year US Treasury notes rose above 1.60% after tepid auction results.
The dollar index rose 0.2% at 91.047, bouncing from Monday's low of 90.679, its weakest level since March 3, though investors were not convinced a recent downtrend had ended.
Risk of sanctions linked to the arrest of Kremlin critic Alexei Navalny upon his return to Russia for the first time since being poisoned last summer hit the rouble on Monday.
Rouble was 0.3% stronger against the dollar at 73.75 and was flat against the euro, trading at 89.45.
