Saudi Arabia surprised the market with a large cut in crude production, an assertion of primacy over the global oil industry that came directly from the kingdom’s de-facto ruler.
The move papered over cracks in the OPEC+ coalition and was a U-turn from some recent Saudi oil-policy priorities, but those things paled in comparison next to the global impact of the decision. Crude prices jumped to a 10-month high and shares of energy giants in London and shale drillers in Texas surged.
