The world is on the brink of the longest-lasting oil glut in at least three decades and OPECs quest for market share makes it almost unavoidable.

Oil supply has exceeded demand globally for the past five quarters, already the most enduring glut since the 1997 Asian economic crisis, International Energy Agency data show. If the Organization of Petroleum Exporting Countries were to keep pumping at current rates it would become the longest surplus since at least 1985 by the third quarter, the data show.
There are few signs the 12-nation group will cut back. Saudi Arabia, OPECs biggest member, will probably increase production to intensify pressure on U.S. shale drillers, Goldman Sachs Group Inc. predicts. OPECs supplies may be swollen further this year if Iran reaches a deal with world powers to ease sanctions on its exports, Commerzbank AG says.
It seems to be taking longer for the oil surplus to clear, and, even without the return of Iran, IEA data indicates it could last for the rest of the year, said Eugen Weinberg, head of commodities research at Commerzbank in Frankfurt. Any expectations the oversupply will be gone by 2016 dont look justified at this stage.
