NEW YORK, May 19 (Reuters) - The dollar fell to a 2-1/2 week low against the euro on Monday as persistently high oil prices and sagging confidence among U.S. consumers renewed concern about the health of the U.S. economy.
Analysts said dealers came into the new week hedging their bets on a sustained dollar rebound, a move that began on Friday after the May Reuters/University of Michigan index of U.S. consumer confidence fell to its lowest level since mid-1980.
Surging oil prices above $127 a barrel also dampened dollar sentiment, as did the 25-year high in short-term inflation expectations seen in Friday's consumer data [
]."What scares people right now is the continued rise in oil prices. Their dollar bullishness is being pared back by the rise in oil prices, as they see OPEC getting more money and putting less into U.S. Treasuries," said Marc Chandler, senior currency strategist at Brown Brothers Harriman in New York.
The euro rose to $1.5632, according to Reuters data, its highest level since May 1, before easing to $1.5585 <EUR=>, up 0.1 percent from late Friday.
The dollar index, a gauge of the greenback against six major currencies, also fell as low as 72.552 <.DXY>, its weakest in over two weeks, before rebounding to 72.765.
The dollar was little changed against the yen at 103.98 <JPY=>, while the Australian dollar scaled a 24-year peak of $0.9564 <AUD=>, boosted by firm commodity prices and expectations that domestic interest rates will stay high.
Chandler said a euro break above $1.5644 could put $1.5720 within reach, though he added that a steady grind back toward its all-time high above $1.60 was unlikely for now.
"That would require further deterioration of U.S. economic fundamentals and more hawkish talk from the European Central Bank," he said.
The U.S. data calendar is light this week, with the highlights likely to come from the producer price index on Tuesday and existing home sales on Friday.
Analyst said robust readings from two German sentiment surveys due later this week would likely add euro support by reinforcing the case for the ECB to leave rates on hold a while longer rather than cutting them.
Germany releases the ZEW economic sentiment index on Tuesday and the Ifo index of German business sentiment on Wednesday.
"Investors might be buying into the idea that the German data -- ZEW and Ifo later this week -- might be a little bit on the firmer side of expectations," said Jeremy Stretch, currency strategist at Rabobank in London.
The surprisingly steep fall in U.S. consumer confidence has left U.S. short-term interest rate futures showing a roughly 80 percent chance of the Fed raising rates by a quarter percentage point to 2.25 percent by year end. They had been fully pricing in such an increase before the consumer confidence data.
Euro zone rates stand at 4 percent, and most analysts expect the ECB to hold them there when it meets next week and to dwell on upside inflation risks.
The Bank of Japan is widely expected to keep interest rates at 0.50 percent at a two-day policy meeting that starts on Monday. [
