The US dollar rose on Thursday in mixed trading amid an improvement in risk appetite with US stocks rising, though investors remain concerned about the impact of the new Omicron strain of the coronavirus and the speed with which the US Federal Reserve will cut stimulus.
Movements in the US currency were limited as investors awaited the November non-farm payrolls report to be released on Friday.
A Reuters poll showed that Wall Street economists estimated that the economy created 550,000 new jobs last month.
In the latest trading, the dollar index, which measures the strength of the US currency against a basket of six major currencies, rose 0.1 percent to 96.131.
The index fell last week after news of the Omicron strain first emerged, but remains close to a 16-month high of 96.938 hit last month.
On Thursday, the United States recorded the second infection with the Omicron strain, but this had a limited impact on stocks and other risky assets.
The dollar rose 0.4 percent against the Japanese yen to 113.155.
However, the British pound rose 0.2 percent to $1.3298, while the euro fell 0.2 percent to $1.1294.
Traders are also awaiting clarifications on how quickly the Federal Reserve will reduce its asset purchases, at a time when central banks around the world are facing difficulties in determining how quickly to undo stimulus measures amid rising inflation.
