LONDON, March 23 (Reuters) - Oil prices rose to around $82 per barrel on Tuesday, bolstered by stronger stock markets after housing data suggested the U.S. economy might be healthier than expected.
Sales of existing U.S. homes fell less than forecast in February, according to the National Association of Realtors in figures that are closely watched for an indication of economic activity in the world's biggest oil consumer. [
]Stock markets rose after the data with the Dow Jones industrial average <
> up 0.4 percent and the FTSEurofirst 300 < > index of top European shares 0.5 percent higher.U.S. crude for May delivery <CLc1> was up 48 cents at $82.08 a barrel by 1450 GMT. The April delivery contract expired on Monday, settling up 57 cents at $81.25.
London Brent crude for May <LCOc1> rose 50 cents to $81.04.
"The tick up came after the housing data," said Christopher Bellew, broker at Bache Commodities, who said oil was trading inside a range that had defined trading for most of the last month. He said the market was looking ahead to more data later.
The American Petroleum Institute (API) was due to release its weekly inventory report at 2030 GMT and was expected to say U.S. crude oil stocks rose 1.3 million barrels last week, a preliminary Reuters poll showed.
Distillate stocks were expected to have eased by 1.1 million barrels, while gasoline stocks were projected to fall 1.6 million barrels. [
]Dealers said the API data could put a lid on oil prices.
"The market is expecting a build in crude inventories," Bellew said.
GREECE
Oil prices have traded above $83 on four occasions this month, but have failed each time to hold the gains, partly due to expectations of an oversupply of oil this year.
World oil demand is still well below its level in 2007, before record prices and recession slashed consumption and global oil inventories are well above their five-year average.
The strength of the dollar has helped hold down oil as concern over Greece's debt crisis has pushed down the euro.
Commodities often move inversely to the dollar as they are priced in the U.S. currency on international markets.
The euro fell against the dollar on Tuesday as uncertainty over possible support for Greece continued in the run-up to an EU summit later this week. [
]Concerns that the EU may not reach a decision this week kept the euro close to a three-week low hit on Monday and fanned risk aversion, supporting safe-haven flows into the U.S. dollar.
The dollar index <.DXY>, a measure of its performance against six other currencies, rose in early trade on Tuesday but then eased back and was flat by 1450 GMT.
EU leaders will discuss the issue of a financial aid package for Greece at a summit in Brussels on March 25-26, after Athens said it could not deliver promised deficit cuts if its borrowing costs remained so high, and that it may have to seek help from the International Monetary Fund.
