A crude price in the $50s is the new reality for bosses of some of the world’s largest producers as output caps from OPEC and its allies are balanced out by rising U.S. shale.

Benchmark Brent crude futures LCOc1 were off by nearly 3 percent at $49.14 per barrel at 1034 GMT (6:34 a.m. ET), down $1.49 from the previous close. U.S. West Texas Intermediate crude CLc1 futures fell $1.45 cents to $46.91 per barrel.

Benchmark Brent oil LCOc1 was down $1.45, or 2.8 percent, at $50.39 a barrel by 1157 GMT (7.57 a.m. ET), after earlier touching $50.13 a barrel, the weakest since May 10. U.S. light crude CLc1 traded at $48.43, down $1.23 cents, or 2.5 percent.

OPEC members and a Russia-led group of 11 non-OPEC countries on May 25th agreed to prolong production cuts for a further period of nine months, beginning from the 1st of July, in a bid to stabilise oil prices and reduce oil inventories. The recent deal was an extension of the previous agreement that was reached between the two sides last December, taking effect from 1st of January this year, to reduce production by 1.8mn barrels per day (bpd) – since when oil prices have remained relatively stable at around the $50/barrel mark.

Ministers from the Organization of Petroleum Exporting Countries and its allies meet in Vienna to decide whether to prolong their agreement. Major producers including Saudi Arabia, Russia and Iraq favor an extension for nine months and, while other options will be discussed, consensus is building around an agreement that runs through next March.
