“While gas prices have drifted lower for the ninth straight week, all eyes now turn to Saudi Arabia after an attack that knocked out over 5% of global oil production and how oil prices are likely to jump as a result,” said Patrick DeHaan, head of petroleum analysis for GasBuddy. “While there is some good news that motorists should not expect a sudden and major uptick in gas prices, there may be a minor impact beginning mid-week and continuing until Saudi Arabia’s state-owned oil company, Aramco, is able to restore all production. However, even after oil production levels return to normal, there is an undeniable factor that will now forever impact oil prices- and that is that Saudi Arabia’s reliability and stability is no longer guaranteed, and this missile strike is evidence that perhaps one of the world’s most stable oil producers may no longer be seen as stable as they were prior to this event. Motorists should stay tuned to GasBuddy for any further developments, but for now, we are not expecting this attack to lead to major price hikes. While the situation may change with Saudi Arabia, motorists are now able to fill up with cheaper winter gasoline and demand continues to seasonally weaken, perhaps softening the blow and impact of the attacks on gas prices.”
