The recent outbreak of war between the United States and Iran has significantly disrupted global supply chains, particularly through the Strait of Hormuz, a critical waterway for oil and gas shipments. President Donald Trump, who had recently touted economic gains such as a rising stock market, declining gas prices, slowing inflation, and dropping mortgage rates, now faces the threat of these gains being reversed due to the conflict [1]. The fighting has rattled markets and led to operational challenges for shipping, with tanker traffic through the Strait of Hormuz dropping around 90% compared to last week, according to MarineTraffic [2]. More than 150 vessels, including oil and liquid natural gas tankers, have been forced to anchor or reroute, causing significant disruptions [2].
Gas prices, which had been a bright spot for the Trump administration, have spiked as a result of the shipping slowdown. The average price for a gallon of gas in the U.S. rose 22 cents over the past week, reaching $3.20 according to AAA, and is now 10 cents higher than one year ago [1][2]. Gas prices could rise another 10 to 30 cents per gallon over the next two weeks, according to Gas Buddy [1]. The disruption has also caused Iraq to cut its oil production due to storage facilities filling up as exports remain at a standstill [1].
Insurance costs for ships passing through the Strait have surged, with war risk policy rates increasing from 0.25% to 1.25% of the ship's value as of Tuesday, and further increases are expected as tensions escalate [2]. Insurers are canceling coverage, creating a coverage gap and further complicating safe passage for vessels [2]. In response, President Trump announced that the U.S. Navy could escort ships through the passageway "if necessary" and that the U.S. International Development Finance Corporation would offer insurance guarantees to shippers [1][2]. However, traffic remains at a near standstill, and it is unclear if any tankers have utilized the government's offer [2]. Jakob Larsen of BIMCO noted that providing protection for all tankers is unrealistic due to the high number of warships and military assets required [2].
The economic impact of the war will depend on its duration, with Trump suggesting it could last four to five weeks but indicating it may stretch longer [1]. The disruption threatens to drive prices higher for American consumers on everything from home loans to groceries, and consumer sentiment has already been falling over the past year [1].
CONCLUSION
The war between the U.S. and Iran has caused a near standstill in shipping through the Strait of Hormuz, leading to a sharp rise in gas prices and significant supply chain disruptions. Insurance costs for shipping have surged, and efforts by the Trump administration to mitigate the impact have so far not restored normal traffic. The ongoing conflict poses a high risk to recent economic gains and is likely to further strain consumer sentiment and inflation.
