Gas Prices Surge Past $4 Per Gallon Following U.S.-Israeli Strikes on Iran

Gas prices have climbed above $4 per gallon nationwide, marking a more than 30% increase since the United States and Israel launched coordinated military strikes on Iran on February 28, 2026. The surge reflects growing market concerns over potential disruptions to global oil supplies amid escalating tensions in the Strait of Hormuz, a critical chokepoint for approximately 20% of the world’s oil trade.

The joint U.S.-Israeli operation targeted Iranian military assets and government infrastructure, resulting in the death of Supreme Leader Ayatollah Ali Khamenei. In response, Iran has threatened to block the Strait of Hormuz and has already launched retaliatory strikes against U.S. Military facilities in the region, Israel, and energy infrastructure in Gulf states.

President Donald Trump announced plans for a U.S. Navy blockade of the Strait of Hormuz, setting a deadline for Iran to fully reopen the waterway or face broader strikes on critical infrastructure. Although a temporary ceasefire was negotiated to allow for diplomatic talks, military vessels approaching the strait are now subject to severe force if deemed a threat, according to Iran’s Islamic Revolutionary Guard Corps (IRGC).

Energy analysts warn that prolonged closure or intermittent disruption of the Strait of Hormuz could sustain elevated fuel prices for six months or longer. The U.S. Department of Justice has also pledged to vigorously prosecute individuals or entities involved in buying or selling sanctioned Iranian oil, further tightening global supply chains.

Despite the blockade announcement, President Trump has publicly urged Iran to reopen the strait to avoid further economic fallout, even as he criticized international figures calling for an finish to the conflict.

As of April 2026, the conflict continues to reshape energy markets, with consumers and businesses bracing for sustained volatility at the pump.
