Higher U.S. gasoline prices resulting from the Iran conflict could negate the tax refunds many Americans expect to receive this year, according to a new analysis from the Stanford Institute for Economic Policy Research (SIEPR). The analysis estimates that the average household will spend an additional $740 on gasoline due to rising global oil prices following the conflict. This figure nearly matches the anticipated increase in tax refunds, which the Tax Foundation estimates will be $748 higher this year, largely due to tax cuts from the Republican-backed “one, big, beautiful bill act” (OBBBA) signed into law by President Trump. As of early March, the IRS reported average tax refunds of $3,676, an 11% increase from the previous year. The financial impact on households will depend on the duration of the conflict and whether the Strait of Hormuz remains open for oil tankers.
Why It Matters
The ongoing conflict in Iran has significant implications for global oil supply and pricing, particularly as the Strait of Hormuz is a critical transit route for oil shipments. The “rockets and feathers” principle suggests that while gas prices rise quickly with increased input costs, they tend to decline more slowly when those costs decrease. As oil prices spiked to nearly $111 per barrel, the national average gas price surged to $3.88 per gallon, reflecting the immediate impact of geopolitical tensions. Tax policies under the OBBBA, which eliminated certain taxes and increased deduction limits, had initially aimed to boost household finances, but rising fuel costs may offset these benefits for many Americans.
