Oil prices posted their strongest weekly gains in months after the United States signaled it may maintain a naval blockade of Iran indefinitely, forcing markets to price in a prolonged disruption to the Strait of Hormuz — the chokepoint that carries roughly one-fifth of global oil consumption and a similar share of liquefied natural gas trade. Brent futures closed Friday at $88.52 a barrel, up 5.9% for the week, while West Texas Intermediate rose 5.4% to $82.40, reflecting a risk premium not seen since the early days of the Red Sea shipping crisis.
The escalation marks a sharp departure from recent diplomatic efforts. Treasury Secretary Scott Bessent said Washington will unveil additional economic isolation measures against Tehran next week, while President Donald Trump asserted U.S. control over Hormuz transit and floated the idea of declaring the strait American territory. Iran dismissed the claims, insisting any decision on the waterway rests with Tehran. Regardless of legal or diplomatic viability, the rhetoric has immediately heightened uncertainty over vessel security and conflict duration.
Analysts warn the market is no longer discounting a temporary interruption. Bjarne Schieldrop of SEB Research noted the U.S. strategy implies a significant extension of tensions, reducing the likelihood of normalized flows in the near term. Shipping data already shows a measurable drop in transits, and insurers are adjusting war-risk premiums accordingly. The rerouting of crude and LNG cargoes around the Cape of Good Hope adds weeks to delivery times and billions to freight costs, a structural shift that could persist well beyond any ceasefire.
For energy importers in Asia and Europe, the calculus is changing. Long-term supply contracts are being reviewed for force majeure exposure, and strategic petroleum reserve releases are under discussion in several capitals. The episode underscores how geopolitical risk in a single waterway can cascade into global price volatility, inventory draws, and accelerated diversification away from Middle Eastern barrels — trends that were already underway but have now acquired new urgency.
