The threat of Iran shutting down shipping in the Strait of Hormuz is creating significant inflationary pressure globally, as a potential oil supply shock could send energy prices soaring. The Iranian parliament’s vote to consider this retaliatory measure, in response to a US attack, underscores the direct link between geopolitical instability and consumer costs worldwide. The International Monetary Fund’s chief, Kristalina Georgieva, has warned that US strikes on Iran could significantly damage global economic growth.
A closure of the Strait of Hormuz, through which a fifth of the world’s oil consumption flows, would inevitably lead to a dramatic increase in energy prices, which would then ripple through various sectors, pushing up production and transportation costs. This would contribute directly to higher inflation and a likely deceleration of global economic activity.
Oil prices initially reacted with a jump of over 5% on Sunday, reaching a five-month high of $81.40. However, prices later retreated, with Brent crude falling nearly 1% to just over $76 a barrel on Monday. Despite this, the potential for dramatic increases remains, with Goldman Sachs estimating oil could hit $110 a barrel if Hormuz flows are substantially reduced for an extended period.
In diplomatic efforts, US Secretary of State Marco Rubio has called any closure of the strait “economic suicide” for Iran and has urged China to use its influence, given its heavy reliance on the waterway. Analysts at RBC Capital Markets are also advising caution, warning of “clear and present risk of energy attacks” from Iranian-backed militias and emphasizing that the situation remains fluid, as evidenced by two supertankers reportedly changing course in the strait.
