The price of oil dropped to near $94 a barrel Monday as a deal between Iran and six world powers on the country's nuclear program raised the possibility that sanctions choking Iranian oil exports will be lifted.
Benchmark U.S. crude for January delivery fell 75 cents to close at $94.09 in New York. Brent crude, a benchmark for international oil used by many U.S. refineries, slipped half a cent to $111 a barrel in London.
The preliminary agreement reached in Geneva Sunday between Iran and the U.S., Britain, France, Russia, China and Germany over Iran's nuclear program does not allow Iran to increase oil exports. But by relaxing some financial restrictions the agreement does make it easier for Iran to sell the oil it is permitted to.
It also removes, for now, the threat of further restrictions on Iranian exports and sets up the possibility that a more comprehensive deal will be struck in the coming months.
The diminished threat to global supplies is likely to make crude cheaper in the short term. And if more Iranian oil returns to international markets, the additional supply is likely to make crude less expensive over the longer term.
"With new domestic output capacity coming on line, plus the potential reemergence of Iranian barrels coming onto the global market, the table is set for lower prices over the longer term," energy analyst Stephen Schork said in a market commentary.
