The closure of the Strait of Hormuz, a critical oil transit route, has resulted in a dramatic reduction in tanker traffic and triggered the largest oil supply disruption in history, according to the International Energy Agency [3]. Tanker transits on Tuesday were reported to be 90% below levels seen on February 27, the day before the U.S. and Israel attacked Iran [3]. Despite a ceasefire agreement between the U.S. and Iran on April 7, transits have remained very low, with only a few very large crude carriers (VLCCs) passing through the strait this week [3]. Rabobank Senior FX Strategist Jane Foley forecasts that even if the war ends this month, oil supplies through the Strait will only recover to 80% of pre-war levels by late August, implying persistent inflation and demand disruption risks for energy importers [1].
The supply shock has led to soaring energy costs, with the U.S. national average gasoline price reaching $4.10 per gallon, according to AAA [2]. This spike has negatively impacted consumers, driving existing home sales in March to their lowest in nine months due to higher mortgage rates [2]. Debit and credit card spending surged 4.3% in March, powered by a 16.5% jump in spending at gas stations, indicating that consumers are feeling the pinch at the pump [2]. However, there was also "healthy growth" of 3.6% excluding gas, suggesting some resilience in consumer spending [2].
Economists cited in the articles believe that the war's impact on U.S. GDP will be modest, potentially shaving off a few tenths of a percentage point overall, but warn that the duration of the conflict is a key variable [2]. If fighting resumes, inflationary impacts could intensify, threatening fragile economic growth [2]. The Federal Reserve has delayed any additional rate cuts, elevating borrowing costs for consumers and adding to economic uncertainty [2].
Energy importers such as the UK and the Eurozone are particularly vulnerable to the negative economic impacts of the spike in oil and gas prices, with worsening terms of trade and rising inflation [1]. Within Europe, some countries are more exposed to energy-related price pressures depending on their energy mix, which has been reflected in bond yields across the region in recent weeks [1]. The International Energy Agency emphasized that resuming flows through the Strait of Hormuz is the single most important variable in easing pressure on energy supplies, prices, and the global economy [3].
CONCLUSION
The closure of the Strait of Hormuz has caused a historic disruption in global oil supply, fueling inflation and economic uncertainty across major economies. While consumer spending remains resilient, elevated energy prices and borrowing costs are weighing on growth prospects. The outlook hinges on whether oil flows through the strait can recover, with analysts warning that prolonged disruption could exacerbate inflation and economic challenges.
