Gas Prices Skyrocket as Trump-Iran War Chokes Global Oil Supply

The U.S.-Iran conflict, ignited on February 28, 2026, has sent energy markets into turmoil, with wholesale prices surging 4% in March from the prior year—the largest annual jump in over three years—driven by an 8.5% spike in energy costs, according to the Labor Department.[1] Oil benchmarks have whipsawed: Brent crude hit $112 per barrel after attacks on over 40 major energy assets, later settling near $104, while West Texas Intermediate reached $104.56 following President Donald Trump's April 12 announcement of a naval blockade against Iran and the Strait of Hormuz.[2][3] Gasoline averaged $4.13 per gallon nationwide per AAA data, with natural gas prices leaping nearly 50% after Qatar Energy halted production due to facility strikes.[2][6] Stalled diplomacy has exacerbated the crisis. Peace talks in Pakistan collapsed last week, hours before Trump's blockade declaration, as Iran rejected U.S. mediation offers and countered with its own ceasefire proposal, yielding no agreement.[2][3] The Strait of Hormuz, vital for 20% of global oil, operates at under 10% of prewar tanker volumes due to Iranian threats and U.S. actions, withholding 10-13 million barrels daily from markets, analysts at PVM Oil Associates and Eurasia Group report.[2][4] The International Energy Agency forecasts a first annual oil demand drop since the pandemic, slashing its 2026 projection by 930,000 barrels per day to a net decline of 80,000 amid infrastructure shutdowns.[1] Economic ripples are hitting American households hard. Consumer prices jumped 3.3% year-over-year in March—the steepest since May 2024—with a 0.9% monthly gain, the biggest in nearly four years, propelled by gasoline surges.[1] Electricity and natural gas costs are climbing nationwide, complicating Federal Reserve efforts as core producer prices rose 3.8% annually despite modest monthly gains.[1][3] Stock markets reflect the strain: the S&P 500 plunged 4.6% and Nasdaq 7.1% in Q1 2026, their worst since 2022.[3] Experts warn of prolonged pain. Goldman Sachs hiked its Q4 Brent forecast to $90 per barrel, citing output cuts and supply risks, while Tamas Varga of PVM noted mounting daily losses from the diplomatic impasse.[4] With core inflation ticking up and Fed policymakers eyeing rate hikes amid Trump's pressure to cut them, the war's energy shock threatens broader U.S. economic stability.[1]
