The average price of OPEC oil prices has fallen to its lowest level since December 2010, just before a string of Arab uprisings pushed oil prices above $100 a barrel. The news underscores the pain faced by members of the Organization of the Petroleum Exporting Countries, most of whom need higher prices to balance their budgets. The organization said Friday that the average price of its members’ crudes basket stood at $88.27 a barrel, compared with $88.32 the previous day. Those levels hadn’t been touched since Dec. 13, 2010. OPEC’s basket price has now fallen lower than the Brent international benchmark, though the latter also fell Thursday below $90 a barrel for the first time since 2012.
