* Dollar falls on signs of weakness in labor markets
* ADP report shows higher-than-expected U.S. job losses
* Markets anticipate ECB rate hike to 4.25 pct (Recasts; adds comments, updates prices)
NEW YORK, July 2 (Reuters) - The dollar dropped against the euro on Wednesday after a report showed the U.S. private sector shed more jobs than expected in June, which may diminish the likelihood of a rate increase by the Federal Reserve.
The ADP Employer Services data, which showed the largest drop since November 2002, is often seen as a precursor to the government's monthly report on the labor market, which is slated for release on Thursday.
The U.S. government report is earlier than usual because of Friday's U.S. Independence Day holiday. Economists polled by Reuters expect another drop in non-farm payrolls last month. For ADP details, see [
].In contrast, investors bought the euro ahead of an expected interest rate hike by the European Central Bank on Thursday. The ECB is widely expected to lift its key lending rate by 25 basis points to 4.25 percent, and President Jean-Claude Trichet's news conference after the meeting may indicate further increases.
Higher benchmark rates in Europe will boost the return of euro-denominated assets and weigh on the greenback.
"The (ADP) headline bodes unfavorably for the U.S. dollar," said Stephen Malyon, senior currency strategist at Scotia Capital in Toronto. "The fact that ADP has not been a good predictor of non-farm payrolls in 2008 could soften the impact, however, given other evidence of a deteriorating labor market, expectations for tomorrow's number have probably worsened."
In late trading in New York, the euro was 0.6 percent higher at $1.5877 <EUR=>, having earlier topped at $1.5888 -- a level last seen in late April, according to Reuters data.
It was 0.5 percent firmer against the Japanese currency at 168.34 yen <EURJPY=>.
More fuel for ECB hawks came from euro zone producer prices, which were above forecast at 7.1 percent year-on-year in May, with euro zone headline inflation running at 4.0 percent.
"The short-dollar bias heading into tomorrow's ECB decision helped to explain the sizable reaction to the ADP report this morning," said Michael Woolfolk, a senior currency strategist at The Bank of New York Mellon.
"The 'trifecta' of an ECB rate hike, hawkish comments by Trichet and a negative non-farm payrolls report should provide sufficient ammunition for speculators to mount an attack on the 1.6000 level in the euro-dollar."
Some analysts did not rule out the ECB hiking by as much as 50 basis points.
"Hiking by 50 (basis points) would help Trichet get a leg up on inflation and this should be positive for the euro even if he says that 50 is all that the market will get this year," Kathy Lien, chief strategist at DailyFX.com, said in a note to clients.
The greenback edged lower against the yen to 105.97 <JPY=> and slid 0.5 percent against a basket of currencies to trade at 72.029 <.DXY>.
