Global oil prices surge following Iran-U.S. war
Oil prices are down on Monday, though such moves have been quick to reverse since the war in Iran began. A barrel of benchmark U.S. crude fell 4% to $94.75, easing some pressure off the economy after topping $102 earlier in the morning. Brent crude, the international standard, fell 1.6% to $101.52 per barrel after earlier getting as high as $106.50.
It’s a reprieve, for now at least, after oil prices spiked from roughly $70 before the United States and Israel began their attacks on Iran. In response, Iran has nearly halted traffic through the narrow Strait of Hormuz, where a fifth of the world’s oil typically sails from the Persian Gulf to customers worldwide. That has oil producers cutting production because their crude has nowhere to go.
The war in the Middle East raged on multiple fronts on Monday, as the U.S. and Israel pummeled military targets in Iran’s capital, Israel stepped up its campaign against Iran-backed militants in Lebanon and Iran retaliated with a drone strike that temporarily forced the closure of Dubai’s airport, a crucial hub for travelers.
Fears of a global energy crisis persisted, even as a small number of ships passed through the Strait of Hormuz. Iranian strikes on commercial ships in and around the strait, and even just the threat of those attacks, have slowed shipping there to a trickle. That has dramatically increased the price of oil and put pressure on Washington D.C. to do something to ease the pain for consumers and the global economy.
