The dollar rose on Wednesday along with global stock markets, also getting lift from strong private-sector U.S. jobs data, while the euro fell back on a report euro zone inflation had turned negative.
The gains kept the dollar on track for a net rise for July, August and September of 0.75 percent, making 2015's third quarter the fourth out of the past five during which the rallying greenback has gone up against other major currencies.
U.S. private employers added 200,000 jobs in September, beating forecasts and hinting jobs growth may be sufficient for the Federal Reserve to raise interest rates later this year, according to the ADP National Employment Report.
The news lifted the dollar index, which measures the U.S. unit's strength against other major currencies. The index was last up 0.5 percent for the day and has been rising since mid 2014 on America's relatively strong economy and high interest rates.
