NEW YORK, May 17 (Reuters) - U.S. oil prices fell to a five-month low below $70 a barrel on Monday on concerns about Europe's economy, the weak euro, swollen U.S. oil inventories and that China's growth may have peaked.
"Concerns about deflation, the European Union and the euro are bringing down most commodities. And it brings back a focus on fundamentals and supplies, which are high," said Phil Flynn, analyst at PFGBest Research in Chicago.
U.S. oil futures hit a 19-month high at $87.15 on May 3 before mounting worries about Europe's debt problems and high oil inventories pushed crude futures prices below $70 a barrel intraday on Monday to their weakest since Dec. 14, 2009.
On Monday at 1:09 p.m. EDT (1709 GMT), U.S. crude for June delivery <CLc1> was down $1.66, or 2.32 percent, at $69.95, having traded as low as $69.27, the weakest since prices fell to $68.59 on Dec. 14.
July Brent crude <LCOc1> fell $3.08 to $74.85 a barrel.
The euro fell against the dollar, slipping to a four-year low at one point, on the persistent fears euro zone austerity measures will curb economic growth in the region and around the globe. [
]The dollar <.DXY> gained 0.5 percent against a basket of currencies.
A strong U.S. currency often pressures commodities by making dollar-denominated commodities, such as oil, more costly for holders of other currencies and by attracting investors out of commodities and into the foreign exchange market. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Volatile trading was expected to be a feature this week with Monday's expiration of the New York Mercantile Exchange June crude options on tap and then Thursday's U.S. June crude contract expiration.
Stockpiles of crude at Cushing, Oklahoma, the delivery hub for the U.S. contract's West Texas Intermediate benchmark crude, have risen in the last eight weeks to a record high 37 million barrels, pushing front-month U.S. crude down relative to later futures contracts <CL-1=R> and the other global crude benchmark, Brent. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

]Iraq's oil minister said on Monday OPEC did not need to meet to discuss output levels because oil markets were balanced. [
