The US dollar fell against most of the other major currencies on Thursday, moving in line with falling Treasury yields, as investors stuck to their views that the Federal Reserve does not need to raise interest rates too much because inflation is starting to get under control.
In evening trading, the dollar index fell 0.2 percent to 103.24.
The euro, which has the largest weight in the dollar index, also rose 0.2 percent to $1.0733.
The British pound rose 0.3 percent against the dollar to $ 1.2114, as the improvement in sentiment towards risk in the markets reinforced both.
The Australian dollar, which is often seen as an indicator of risk appetite, rose 0.8% to $0.6973.
The dollar rose 0.1 percent against the Japanese yen to 131.575 yen.
