The Iran war, which began on February 28, 2026, has caused significant disruption in global energy and supply chains, leading to a surge in oil prices and widespread economic consequences [2][3]. Iran has effectively blocked shipping through the Strait of Hormuz, a critical channel through which more than 20% of the world’s oil supply typically moves, resulting in a more than 90% reduction in tanker traffic in March [2]. Only 55 to 60 tankers have cleared the strait in the first 28 days of the conflict, compared to over 100 ships per day before the war [2]. Some tankers associated with India and China have been allowed to pass, but most remain stranded in the Persian Gulf [2].
As a result of the supply disruption, oil prices have soared. U.S. West Texas Intermediate (WTI) crude has risen more than 50% since the war began, while Brent crude has jumped nearly 60% [2]. On Monday, U.S. crude oil settled above $100 per barrel for the first time since Russia's invasion of Ukraine in 2022, and Brent is poised for its largest one-month increase on record [2]. Technical analysts note Brent crude prices are testing $90 per barrel, with support at $85, and further escalation or confirmation of large-scale U.S. exports to China could trigger additional price movements [1].
China is responding to the turmoil by preparing to resume purchases of U.S. crude oil and liquefied natural gas, with tankers set to load 600,000 barrels of American oil per day at Corpus Christi, Texas [1]. This marks a shift after a period of reduced American oil and gas purchases due to trade tensions, as China now prioritizes supply stability [1]. Analysts believe this move could help ease pressure on China's energy supply and dampen price volatility, but ongoing geopolitical risks may keep prices elevated [1].
The surge in oil prices has had direct effects on consumers and businesses. The average U.S. gasoline price hit $4.02 per gallon, up more than a dollar in a month, while diesel fuel rose to $5.45 per gallon, $1.80 higher than a year ago [2]. Economists estimate the average U.S. household will spend an additional $740 on gas this year [2]. Airlines have been immediately impacted, with jet fuel prices up 103% compared to a month ago [3]. Retailers and consumer goods companies, including Unilever, are facing supply chain disruptions and inflationary pressures, prompting Unilever to implement a three-month global hiring pause to address 'significant challenges' [3]. Unilever had previously committed to 800 million euros in cost savings, reducing 7,500 office-based roles, and expects further savings in 2026 [3].
Economists and industry analysts warn that rising gasoline and energy costs could dampen consumer spending on discretionary items, and disruptions to fertilizer shipments through the Strait of Hormuz may push global food prices higher, affecting farmers during the crucial spring period [2][3].
CONCLUSION
The Iran war has triggered a cascade of disruptions across global energy and supply chains, sending oil prices above $100 per barrel and prompting companies like Unilever to pause hiring. Consumers face higher fuel and food costs, while China seeks to stabilize its energy supply by resuming U.S. imports. Market volatility remains high, with further escalation or supply shifts likely to sustain upward pressure on prices.
