Gas Price Spike Eats Trump's $740 Tax Refund Boost

Gasoline has jumped almost a dollar per gallon in the past month after U.S. military strikes on Iran closed the Strait of Hormuz, according to Fortune's market tracking. The waterway carries 20% of global oil exports, and its shutdown has traders pricing in sustained supply shortages through summer driving season. AAA data shows the national average now sits near $3.90, up from $2.95 in early February. Every major newsroom from CNN to CBS News reports the same pattern: geopolitical risk premium layered on top of normal spring refinery maintenance.

The White House claimed January delivered the "largest tax refund season in U.S. history" thanks to Trump's One Big Beautiful Bill Act (OBBBA). Treasury projections showed the average household receiving an extra $748 this filing season through expanded child credits and adjusted brackets. That figure matches independent analyses from the Tax Policy Center and Penn Wharton Budget Model. Most refunds hit bank accounts between late January and mid-March, just as pump prices began their climb.

Goldman's commodities team sees oil staying above $85 per barrel through Q3, which translates to roughly $3.80-$4.20 gas nationwide. Their household impact model shows the average family will pay $740 more for fuel in 2026 versus last year. That's within $8 of the projected $748 refund increase, essentially a wash. Rural drivers face even worse math since they log 30% more miles annually. The investment bank published the note March 20 and it circulated widely among trading desks before hitting financial media.

Anyone commuting more than 30 miles daily gets hit hardest. A two-car suburban family driving 25,000 combined miles at 25 mpg will burn an extra $800-900 this year. Lower-income families feel it worse since fuel takes up 8-12% of their budgets versus 3-4% for top earners. City dwellers with transit options and remote workers come out slightly ahead, keeping most of their refund bump. Geographic patterns matter too: Gulf Coast refineries normally supply the Southeast cheaply, but shipping delays from Hormuz closures have even Texas seeing $3.60 gas.

The timing is brutal. Trump's team planned to run midterm ads touting bigger refunds as proof his tax cuts delivered for regular families. Instead, gas station sticker shock dominates local news. Republican strategists told PBS that pocketbook issues override tax messaging when voters fill up weekly. Early polling from CNN shows 60% of Americans blame "foreign policy decisions" for higher pump prices, which could shift blame toward the administration. The White House now pivots to releasing strategic petroleum reserves and pressuring Gulf allies to pump more.

Consumer spending was supposed to get a spring boost from refund season. JPMorgan Chase payment data already shows discretionary purchases flat since mid-March despite refund deposits hitting accounts. Gasoline demand typically rises 15% from March to May, but current pricing could suppress that by 3-5%, according to Energy Department modeling. Airlines and shipping firms are passing fuel surcharges to customers, creating a secondary inflation wave. The Atlanta Fed's GDPNow estimate shaved 0.3 percentage points off Q2 growth projections due to higher energy costs.

Two scenarios drive most forecasts. If Hormuz reopens within 60 days, gas likely retreats to $3.20-3.40 by summer. If the closure persists through fall, $4.50+ becomes probable and the Federal Reserve might delay rate cuts to fight energy-driven inflation. OPEC+ has spare capacity but wants higher prices to fund member budgets. Domestic producers can't drill fast enough to offset 2 million barrels per day of lost Persian Gulf exports. Most analysts (and Vegas betting markets) give 60-65% odds of partial reopening by June.
