LONDON, May 20 (Reuters) - Oil fell towards $68 a barrel on Thursday, the lowest level in nearly eight months on concerns that the European debt crisis will cut both risk appetite and demand for oil.
Worries that the Greek fiscal problems could spill over to other economies has knocked oil prices down by around $20 from the $87.15 a barrel peak in early May.
Oil extended early losses on Thursday after U.S. jobless claims rose unexpectedly and global stocks slid lower. [
] [ ]"The fiscal crisis in Europe has been an eye-opener for markets. Even though we have a recovery, it's clear that it will be slow and painful and it's the same for oil demand," said Christophe Barret, oil analyst at Credit Agricole CIB.
U.S. crude <CLc1> for June delivery fell $2.15 to $67.72 a barrel by 1243 GMT, falling below the near eight-month low hit the previous day. It earlier rose more than $1 as traders rushed to cover short positions ahead of the contract's expiry today before again falling sharply.
The July contract fell $2.44 to $70.04 a barrel by the same time. ICE Brent futures <LCOc1> were down $2.42 at $71.27 a barrel.
The euro traded near four-year lows against the dollar on Thursday as uncertainty over unity in the euro zone prevailed following Germany's solitary move to ban naked short-selling on Wednesday. [
] <EUR=>A weak euro tends to weigh on oil prices as it makes dollar-denominated commodities more expensive for holders of the currency.
The German ban has also curbed buying appetite for commodities such as oil amid concern other eurozone members will follow and is contributing to the price slide, analysts said. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

BELOW RANGE
Oil prices this week have fallen below the $70-$80 a barrel range that many members of the Organization of the Petroleum Exporting Countries (OPEC) have said is fair for both producers and consumers.
But OPEC officials have stopped short of calling for any immediate steps to prop up the market. [
]Some analysts attribute the weakness of U.S. crude partly to a regional supply glut at the Cushing delivery point for West Texas Intermediate (WTI) where stocks are at a record high of 37.9 million barrels.
The sell-off in the alternative global oil benchmark ICE Brent has been less pronounced than on WTI and the spread between the two contracts was around $3 on Thursday, with Brent at a premium.
Oil prices briefly rallied on Wednesday after U.S. weekly inventory data showed a smaller-than-expected 200,000 barrel rise in crude stocks.
The data also showed a surprise decline in distillates and a smaller than forecast drop in gasoline, stirring hopes that fuel demand in the number one oil consumer is improving. [
]Oil demand is historically weakest in the second quarter between the northern hemisphere winter heating oil season and the summer gasoline season.
Key macroeconomic data due out of the U.S. later on Thursday including leading indicators for April at 1400 GMT are set to provide further market direction, analysts said.
Eurozone consumer confidence data could also give prices a steer, they added. (Additional reporting by Judy Hua in Singapore; editing by James Jukwey)
