Concerns about the rapid end of the war in Iran are driving the appreciation of the dollar.

The US dollar rose as doubts about a rapid end to the Iran war weakened risk appetite and pushed up oil prices. US President Donald Trump said in a prime-time speech on Wednesday that the US would launch "extremely heavy strikes against Iran in the next two to three weeks." The day before this statement was made, Trump had said that the United States would withdraw from Iran in two to three weeks, crushing hopes that the conflict would soon come to an end. The US dollar was boosted by its safe-haven status and the United States' position as a net oil exporter. The DXY dollar index rose by 0.5% to 100.111.
