Oil prices surged to $108.59 per barrel for Brent crude and $103.22 per barrel for U.S. crude on Friday, marking the highest levels since May. The increases follow confirmed reports that Saudi Arabia’s crude oil output dropped to its lowest level since 1990, attributed to renewed hostilities with Iran. Traffic through the Strait of Hormuz, a critical global oil transit route, remains well below pre-war levels, according to ING commodities strategists Warren Patterson and Ewa Manthey.
Iran-linked Houthi forces seized Yemen’s port of Mocha on Thursday, further threatening Red Sea shipping lanes. Meanwhile, Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed responsibility for attacks on 10 ships near the Strait of Hormuz on Wednesday, escalating tensions after the U.S. targeted five Iranian oil tankers. The U.S. has warned of potential retaliatory strikes, including against Iran’s Pickaxe Mountain near the Natanz facility, while Iran vowed to escalate its response to any further aggression.
Oil prices have climbed nearly 13% this week, the steepest increase since mid-July, driven by supply disruptions and geopolitical risks. The U.S. national average diesel price surpassed $6 per gallon for the first time, while gasoline prices rose to $4.27 per gallon, reflecting broader fuel market pressures. Analysts note that China’s demand outlook will heavily influence the durability of the rally, with OPEC also revising its demand forecast downward amid persistent supply concerns.
Immediate Market Impact
Global equities declined as oil prices rose, with Japan’s Nikkei 225 dropping 2.8% and South Korea’s Kospi falling 2.3%. U.S. Treasury yields spiked, with the 10-year yield reaching 4.9%—its highest since 2023—as investors priced in energy-driven inflation risks. The Shanghai Composite index dropped 1.8%, while India’s Sensex fell 1%, reflecting broader market unease over prolonged supply disruptions.
U.S. President Donald Trump stated on Wednesday that oil prices would not decline until after the November midterm elections, contradicting earlier assurances of a quick resolution to the conflict. Commodities experts have warned that Brent crude could rise to $120–$150 per barrel if tensions persist, with Saudi Arabia’s output decline underscoring the market’s vulnerability.
Geopolitical Escalation
The Strait of Hormuz, through which 20% of the world’s oil passes, has seen traffic restrictions intensify amid tanker attacks and military posturing. Iran’s IRGC justified its ship attacks as retaliation for U.S. actions, while the U.S. has signaled readiness to respond to further provocations. Houthis’ seizure of Mocha port adds a new dimension to the crisis, threatening Red Sea shipping routes critical to European and Asian energy supplies.
Saudi Arabia’s lowest output since 1990—reported by Bloomberg but not independently confirmed by NBC News—highlights the strain on regional oil production. The U.S.-Iran standoff has also disrupted global supply chains, with diesel and gasoline prices surging in the U.S., where the average diesel price hit $5.97 per gallon.
Economic Ripple Effects
Rising oil prices have triggered sell-offs in global equities, particularly in tech-heavy markets like South Korea and Japan. Chinese AI chipmaker Enflame surged 180% in its trading debut, but broader indices in Hong Kong and Australia declined. The S&P 500 fell 0.6% for a fourth straight day, reflecting investor caution amid energy market volatility.
Analysts at ING noted that the fragility of the situation is underscored by the persistent geopolitical risks in the Persian Gulf, with no credible path to de-escalation. The U.S. Treasury bond sell-off, driven by energy inflation, has pushed mortgage rates higher, further straining consumer finances.
Outlook and Key Factors
The trajectory of oil prices will depend on three critical developments:
- China’s demand recovery: Analysts warn that the oil rally’s sustainability hinges on Chinese consumption trends.
- Iran-U.S. negotiations: No formal talks have been reported, and both sides have signaled escalation rather than compromise.
- Saudi Arabia’s production capacity: With output at multi-decade lows, any further disruptions could exacerbate supply shortages.
OPEC’s revised demand forecast suggests weakening global consumption, but the group has not indicated plans for immediate production adjustments. The market remains highly sensitive to geopolitical developments, with traders closely monitoring the Strait of Hormuz and Red Sea for signs of further escalation.
