OIL-Barrel DLRS falls to 68 per dollar, position limits

Oil fell on Monday to $ 68 a barrel after the decision of a major U.S. stock exchanges to set limits on long positions increased uncertainty.

U.S. crude for October fell 59 cents to $ 68.70 at 1243 GMT after touching a low of $ 68.02. Brent crude was at $ 67.5.

The Chicago Mercantile Exchange on Friday pledged to enforce the current limits of positions in the New York Mercantile Exchange in the plaza and other financial markets since Sept. 14.

Operators are on position limits could face fines or could be found guilty of price manipulation, unless they obtain a waiver, according to a notification of the Chicago Mercantile Exchange.

Oil fell nearly 4 percent on Friday, towards $ 69 a barrel, giving most of the week's gains after U.S. stocks fell after a five-day rally, raising questions about the sustainability of its recent recovery and the strength of the U.S. economic recovery.
