OPEC

The cost is at a 4-month low. What's going on?

OPEC predicts oil prices will hang below $100 a barrel for as long as a decade.

Oil, whose price has halved in the past year, accounts for 95 percent of the country’s exports and 45 percent of the government’s budget.

Members of the oil cartel could get higher prices if they cut production but there would be a cost.

With oil prices falling, the group will have to give up market share or profits.

Changes in global supply and demand have weakened OPEC's influence in the market.

A global glut of oil has potential to pit key suppliers in a price war.

Ultralight oil made by fracking is seeping through cracks in the U.S. ban on oil exports.

The boom in U.S. oil production has disrupted global oil’s pecking order and caused fractures inside the once all-powerful OPEC.

OPEC earned a record $1 trillion in revenues in 2012, and the average price of oil was the highest ever.
