In September, despite a global oil glut developing largely because of China’s slowdown and the rapid increase in U.S. production, the Saudis boosted production half a percent, to 9.6 million barrels a day, lifting OPEC’s combined production to an 11-month high of almost 31 million barrels a day.
Then, on Oct. 1, Saudi Arabia lowered prices by increasing the discount it offered its major Asian customers. The kingdom might just as easily have cut production to defend higher prices. Instead, the Saudis sent a strong signal that they were determined to protect their market share, especially in India and China, against Russian, Latin American, and African rivals. Iraq and Iran followed suit.
