NEW YORK (MarketWatch) -- The U.S. dollar remained higher Wednesday after ADP Employment Services said private companies slashed 532,000 jobs in May, after a 545,000 drop in April that was revised lower. The dollar index (DXY 78.98, +0.57, +0.73%) , which measures the performance of the greenback against a basket of currencies, rose to 79.006, up from 78.477 in late North American trading Tuesday. The dollar was gaining against the euro and other major currencies, finding support on a news report that signaled major Asian central banks are prepared to keep buying U.S. Treasurys.
