Hormuz in the balance: US demands Iran pledge, Europe weighs tolling plan as oil ends week 6% higher
US officials are pressing Tehran to make a public statement that the Strait of Hormuz is open and that shipping can pass safely, as a fragile ceasefire holds after two days of US-Iran clashes. Separately, Europe is studying proposals that would allow Iran to charge non-compulsory navigational fees in the strait — provided the UN's maritime regulator endorses them. UK Deputy PM David Lammy warned that compulsory tolls would be 'disastrous'. Oil prices slipped on Friday on hopes of continued diplomacy but still closed the week roughly 6% higher.
The Strait of Hormuz is the single most critical oil chokepoint on the planet — roughly 20% of global oil supply transits it daily. A sustained closure or even a credible threat of disruption sends Brent crude sharply higher, feeding inflation in every oil-importing economy. The week's 6% oil price surge is already transmitting into higher fuel costs, wider current-account deficits for importers, and upward pressure on sovereign bond yields in emerging markets. The tolling proposal adds a new legal and diplomatic dimension: if non-compulsory fees gain UN backing, it sets a precedent that could embolden future attempts at mandatory charges, fundamentally threatening freedom of navigation.
