The ongoing war in Iran has triggered a significant disruption in global energy production, with Iran closing the Strait of Hormuz to oil tankers and a U.S. Navy blockade preventing Iran from selling its oil. This has led to a sharp surge in oil prices, affecting consumers worldwide as the conflict enters its third month [1][2]. Gasoline prices in the U.S. have reached their highest levels since 2022, with the national average hitting $4.30 per gallon, up 44% from $2.98 before the war began following U.S. and Israeli attacks on Iran on February 28 [1][2]. Diesel prices have also climbed steeply, averaging nearly $5.50 per gallon, compared to $3.76 pre-war [1]. Jet fuel prices spiked to $209 a barrel in early April before easing to $179, still significantly higher than the $99 at the end of February [1].
The surge in fuel costs is impacting various sectors: shippers have added surcharges, including an 8% temporary charge by the U.S. Postal Service and a 3.5% fuel and logistics surcharge by Amazon for third-party sellers [1]. Airlines have raised baggage fees and introduced new charges for seat selection, with major U.S. carriers and international airlines increasing fuel surcharges [1]. The inflation gauge favored by the Federal Reserve, the Personal Consumption Expenditures price index, rose 0.7% from February to March and 3.5% year-over-year, marking the fastest pace since May 2023 [2]. Gasoline prices alone jumped 21% in March from February, creating the largest disruption of oil supplies in history [2].
Despite these challenges, the U.S. economy has shown resilience. Gross domestic product grew at a steady 2% annual pace from January through March, rebounding from 0.5% growth in the previous quarter, which was affected by a 43-day federal government shutdown [2]. Business investment, driven by the artificial intelligence boom, surged 10.4% in the first quarter, the biggest jump in nearly three years [2]. According to Fox Business, business investment is up 17% in the first quarter and almost 10% over the past year, with real GDP increasing 2.7% over the past year [3]. Record-breaking tax refunds from President Trump's 2025 tax cuts have helped offset the increased burden of gasoline spending, with more than 50 million Americans benefiting [2][3]. Consumer spending expanded at a 1.6% annual pace from January through March [2], and Fox Business reports consumer spending up nearly 2.5% over the past year [3].
However, economists warn that the positive effects of tax refunds may be short-lived. Michael Pearce of Oxford Economics notes that as tax refund season winds down and gas prices continue to climb, the hit to consumer spending will become more evident from May [2]. Joe Brusuelas, chief economist at RSM, has downgraded his forecast for U.S. economic growth this year to 1.7% from 2.4% due to rising gas prices [2]. Fox Business emphasizes the strength of the American economy despite the gas price spike, highlighting a record-breaking stock market and ongoing business investment, while also noting the severe economic impact on Iran, including a currency crisis and massive inflation [3].
CONCLUSION
The Iran war has caused a sharp rise in oil prices, leading to higher costs for consumers and businesses in the U.S. and globally. While tax refunds and an AI-driven investment boom have temporarily cushioned the economic impact, economists expect consumer spending and GDP growth to slow as gas prices remain elevated. The market impact is high, with continued uncertainty as the conflict persists.
