The immediate impact of escalating US-Iran tensions is being felt directly in maritime navigation, with two supertankers reportedly making U-turns in the Strait of Hormuz over the weekend. This incident underscores the heightened uncertainty and operational risks for global shipping in the vital waterway. The International Monetary Fund chief, Kristalina Georgieva, has warned that US strikes on Iran could significantly damage global economic growth, largely due to potential energy price surges.
The Strait of Hormuz is a critical chokepoint through which a fifth of the world’s oil flows. The Iranian parliament’s recent vote to consider shutting down this channel, in retaliation for a US attack, poses a severe threat of an oil supply shock. Such a disruption would inevitably drive up energy prices, exacerbate inflation, and impede global economic expansion, creating widespread ripple effects.
While oil prices initially jumped over 5% on Sunday, hitting a five-month high, they later retreated, with Brent crude falling to just over $76 a barrel on Monday. However, the potential for extreme price hikes remains, with Goldman Sachs estimating oil could hit $110 a barrel if Hormuz flows are significantly curtailed for an extended period. This emphasizes the vulnerability of the global economy to regional instability.
Adding to the diplomatic pressure, US Secretary of State Marco Rubio has declared that closing the strait would be “economic suicide” for Iran, urging China to influence Tehran given its reliance on Hormuz for oil. Analysts at RBC Capital Markets have also cautioned against complacency, warning of “clear and present risk of energy attacks” from Iranian-backed groups and noting the fluidity of the situation, as exemplified by the supertanker movements.
