The dollar climbed to fresh highs on Wednesday, getting lift from solid U.S. jobs and business data, as the euro sank below $1.11 to an 11-1/2 year low ahead of the launch of quantitative easing by the European Central Bank.
The dollar hit its highest since September 2003 against a basket of currencies and was last up 0.6 percent at 95.958. Earlier it struck a high of 96.059.
The ADP National Employment Report showed a gain of 212,000 private-sector jobs. Economists surveyed by Reuters had forecast the ADP to show a gain of 220,000 jobs.
Separately, the Institute for Supply Management said its services index was 56.9 in February, up slightly from 56.7 in January. Analysts were looking for a reading of 56.5, according to a Reuters poll.
The ADP data likely signaled strength in Friday's potentially markets-moving government jobs report for February, according to Camilla Sutton, chief currency strategist at Scotiabank in Toronto.
