The ongoing war between the U.S., Israel, and Iran has triggered a rapid and significant surge in global oil and gas prices, with widespread disruptions to energy and shipping markets. Oil prices soared above $90 a barrel on Friday, with American crude settling at $90.90, up 36% from a week ago, and Brent crude climbing 27% to $92.69 over the same period [1]. U.S. gasoline prices rose to $3.32 per gallon, an 11% increase from a week earlier, while diesel prices jumped 15% to $4.33 per gallon [1][2]. The price shocks were even more pronounced in Europe and Asia, where diesel prices doubled and jet fuel prices rose by nearly 200% in Asia [1].
The conflict has resulted in the effective closure of the Strait of Hormuz, a critical chokepoint through which roughly 20 million barrels of oil pass daily, representing about 20% of global oil flows [1][4][5][6]. This has left ships stranded in the Persian Gulf and halted the flow of oil, gas, and other commodities, causing severe supply chain disruptions. Shipping giant Maersk suspended two key services linking the Middle East to Asia and Europe, with 147 container ships sheltering in the Persian Gulf and shares of Maersk falling 0.6% on the news [5]. The closure of the strait has also added 10-14 days to transit times for vehicle and parts shipments, increasing logistics costs and delaying deliveries [4].
The energy supply shock is complicating economic policy, particularly for the U.S. Federal Reserve. The surge in oil prices and shipping disruptions are fueling inflation, which remains above the Fed's 2% target at 2.4%, while the U.S. labor market shows signs of weakness, with 92,000 jobs lost last month and downward revisions to previous months' data [2]. This raises the risk of stagflation, making it harder for the Fed to cut interest rates and support growth [2]. Gregory Daco, chief economist at EY, noted that the conflict raises inflation risks while also heightening concerns about downside risks to growth and employment [2].
The automotive sector is also feeling the impact. Toyota, Hyundai, and Chinese automakers such as Chery, which together account for about a third of Middle East auto sales, face significant risks from the conflict and supply chain disruptions [4]. Stellantis (STLA) shares slumped 11% since last Friday, attributed to rising gasoline prices and the company's reliance on gas-powered vehicles [4]. Bernstein analysts noted that while the immediate effect on Japanese automakers is limited, the situation requires close monitoring [4].
In response to the supply crunch, the U.S. granted India a 30-day waiver to resume Russian oil purchases, aiming to ease global supply worries [6]. India, the world's third-largest oil importer, has reportedly bought up to 6-8 million barrels of Russian oil in recent days [6]. However, analysts such as Vandana Hari of Vanda Insights warn that the waiver is only a temporary relief and that the chances of the Hormuz blockade being lifted soon are "extremely dim" [6]. U.S. President Donald Trump stated that further action to stabilize oil prices is imminent, but market experts expect Brent crude to continue rising [6].
Geopolitically, the war has heightened tensions between the U.S. and China, with Beijing opposing the U.S.-Israel offensive in Iran. This backdrop is expected to influence upcoming trade talks between Presidents Trump and Xi Jinping, as well as negotiations on tariffs and commodity deals [3]. The conflict has also affected global trade sentiment, with Maersk's disruptions seen as a bellwether for broader supply chain risks [5].
CONCLUSION
The Iran war has caused a sharp spike in oil and gas prices, severe disruptions to global shipping and supply chains, and heightened inflationary pressures worldwide. Key sectors such as automotive and shipping are already experiencing significant impacts, and central banks face increased challenges in balancing inflation and growth. With no resolution in sight and critical chokepoints like the Strait of Hormuz remaining closed, markets are bracing for continued volatility and elevated energy costs.
