* Euro at 14-month low versus dollar, helps pressure oil
* API data showed crude stocks up more than expected
* Coming up: EIA inventory data at 10:30 a.m. EDT
NEW YORK, May 5 (Reuters) - U.S. crude futures fell sharply on Wednesday, dropping below $80 a barrel as the euro weakened and ongoing concerns that the Greece debt crisis might spread to other euro zone countries kept investors risk adverse.
Rising U.S. inventories and demand concerns also weighed on the market after an industry group's weekly report on Tuesday showed crude supplies rose much more than expected.
"Crude and products futures continued to slide on heavy overnight volume as the dollar made further gains against the euro," said Addison Armstrong, analyst at Tradition Energy.
The euro extended losses, falling to a 14-month low against the dollar as fear that European debt problems might spread pressured the currency and triggered automatic sell orders beneath $1.29 to levels not seen since mid-March 2009. [
