While the redundancies in Saudi oil infrastructure mean that output may be restored as soon as Monday, the attack could build in a premium to oil prices that has long been absent due to complacency. Indeed, traders may now need to factor in new risks that threaten to take not hundreds of thousands but millions of barrels off the market at a time. U.S. shale production may have upended the world energy market with nimble output, but the market’s reaction time is several months, not days or weeks, and nowhere near enough to replace several million barrels.
After the smoke clears and markets calm down, the technological sophistication and audacity of Saturday’s attack will linger over the energy market.
