The dollar index was little changed on Wednesday, hovering near four-week highs around 98.5, as traders assessed a fresh batch of key economic data alongside ongoing geopolitical tensions. The ADP employment report continued to point to a gradual cooling in the US labor market, reinforcing expectations that the Fed will continue with interest-rate cuts this year. US private-sector employment rose by 41K jobs in December, rebounding from a revised decline of 29K in November but falling short of forecasts for a 47K increase. Investors are now awaiting the JOLTS job openings data due later today, ahead of the closely watched nonfarm payrolls report on Friday. Geopolitical concerns also weighed on sentiment, with a worsening backdrop that includes US actions in Venezuela, renewed threats of intervention in Greenland, and rising tensions between China and Japan. The greenback was little changed against the euro and the pound, while edging slightly higher versus the yen and the Swiss franc.
