If Iran Blocks Strait of Hormuz, What Will Happen to U.S. Energy Costs?
Iran is reportedly weighing blocking a key commercial choke point known as the Strait of Hormuz, a move that could drive up energy costs in the U.S. and across the globe, according to energy sector experts who spoke with the Daily Caller News Foundation.
Israel began to bombard Iran to eliminate the Islamic Republic’s ability to build a nuclear weapon on June 13, and the U.S. carried out “Operation Midnight Hammer” on Saturday night, bombing three of Iran’s nuclear facilities. While Iran’s parliament has reportedly voted to close the Strait of Hormuz in a retaliatory move to choke the world’s oil supply in response to the American strikes, the U.S. is well-positioned to combat the inevitable energy cost spike that would follow if Iran succeeds, sector experts told the DCNF.
“The escalating conflict between Iran and Israel is already putting upward pressure on oil and natural gas prices—and that pressure will intensify if the Strait of Hormuz is blocked,” Trisha Curtis, an economist at the American Energy Institute, told the DCNF. “This kind of disruption would send global prices higher and tighten supply chains. Fortunately, the U.S. is well-positioned to respond — our domestic production strength and growing export infrastructure make American oil and natural gas increasingly indispensable to global markets.”
Iran does not have the legal authority to halt traffic through the strait, meaning it would need to usurp control through force or the threat of force, according to legal scholars and multiple reports. The Iranian parliament’s reported move to block the Strait on Sunday awaits final approval by Iran’s Supreme Council, according to Iran’s Press TV.
The Strait is only 35 to 60 miles wide and connects the Persian Gulf to the Indian Ocean, flowing past Iran, the United Arab Emirates and Oman. The thoroughfare is vital for global trade, as tankers carried one fifth of the world’s oil supply through the Strait of Hormuz in 2024 and the first quarter of 2025, according to data from the U.S. Energy Information Administration.
