And that's not really what drive prices down. They had been creeping down all last year, but what triggered the slump was SA vowing not to cut production, even if it cut into national budgets.
Basically they launched a price war against the shale producers in the us. Their production costs are much lower, and it's a nationalized industry, so they can afford to bury the us producers.
Yeah and while SA can support low prices, most of OPEC can't do the same though. It isn't just the shale producers that need the higher prices.
