The Iran war, which ended with a framework agreement in June 2026, may have been relatively short in duration, but its repercussions are far-reaching and enduring. The conflict, which pitted the U.S. and Israel against Iran, resulted in significant human and economic costs, disrupting global energy markets and supply chains. As the world grapples with the aftermath, the true extent of the war’s impact is becoming increasingly clear.
The war claimed the lives of 13 U.S. service members, over 3,300 Iranians, 3,826 in Lebanon, nearly 60 in Israel, and dozens across Gulf states. Beyond the human toll, the conflict has had profound economic implications, affecting everything from energy prices to mortgage rates and global trade.
The Economic Toll on the United States
The economic impact of the Iran war on the United States has been substantial. According to Moody’s Analytics, the conflict has cost U.S. consumers and taxpayers about $132 billion so far, with the financial burden continuing to rise. One of the most visible effects has been the surge in energy prices, driven by the near shutdown of the Strait of Hormuza critical artery for crude oil.
Gasoline prices, which averaged just under $3 a gallon when the war began, soared to a peak of $4.56 a gallon. With U.S. motorists consuming between 360 million to 380 million gallons of gasoline daily, the wartime surcharge added more than $360 million a day in higher costs at the pump. While gas prices have since cooled, they remain elevated compared to pre-war levels.
The war also led to a significant increase in diesel fuel prices, jumping from $3.76 a gallon to a peak of $5.69 in early April. This surge in transportation costs has affected everything from trucking to airline tickets, which have seen a nearly 27% increase over the last year. Additionally, the conflict has contributed to a rise in mortgage rates, making home purchases more expensive and keeping potential buyers out of the market.
Global Economic Disruptions
The Iran war has delivered a tumultuous blow to the global economy. This month, the World Bank cut its 2026 global economic growth forecast to 2.5%, the lowest since the coronavirus pandemic. The conflict has exacerbated slowing economic growth and rising inflation, particularly in Europe, while causing shortages of fertilizer and cooking gas in countries like India.
Middle Eastern countries have borne the brunt of the economic downturn. The World Bank estimates that the Gulf economies’ gross domestic product will expand by just 1.3% this year, down from 4.5% in 2026. The conflict has also had a devastating impact on the region’s aviation sector, with flights out of Dubai and Doha reduced by two-thirds and three-quarters, respectively. The lucrative tourism industry has also suffered, with conferences postponed and hotels emptied.
The war’s disruptions to supply chains have contributed to global poverty and hunger, according to U.N. agencies. The blockade on the Strait of Hormuz choked oil and gas exports, forcing Middle East producers to lower crude oil production by more than 11 million barrels a day in May compared to pre-conflict levels. The full reopening of the strait, expected as part of the framework agreement, is crucial for restoring confidence in energy supply chains.
Military and Political Costs
The military costs of the Iran war have been substantial. The latest tally on operational costs is $29 billion, according to Pentagon comptroller Jules Hurst. This figure does not include the cost to repair U.S. bases in the Middle East, which were attacked by Iranian drones and missiles. The political cost of the war has also been tangible, with President Trump’s net approval rating dropping to -22 percentage points by the end of May.
As the world moves forward from the Iran war, the focus shifts to reconstruction and development. The memorandum of understanding between the U.S. and Iran includes a plan for $300 billion toward Iran’s reconstruction and development after the war. However, the road to recovery is likely to be long and complex, with significant challenges ahead.
