Strait of Hormuz: Trump urges nations to secure shipping lanes

President Donald Trump said he has asked “about seven” countries to send warships to help secure the Strait of Hormuz after maritime traffic there effectively ground to a halt amid the war with Iran, and he warned that Washington will “remember” which nations assist.

The development followed a series of strikes and warnings that prompted many commercial vessels to avoid the strait, a choke point through which a significant share of the world’s seaborne oil normally transits. Marine intelligence firms and shipping trackers reported dramatic drops in tanker transits and widespread turnarounds or diversions, reflecting high operational risk for vessels in the Gulf approaches.

That disruption reverberated through energy markets as benchmark crude prices rose and some operators rerouted cargoes to Red Sea terminals and alternate pipelines. Analysts noted that even if transits resume, repositioning tankers, loading from storage and restarting field operations could take days to weeks, sustaining near-term price volatility and logistical bottlenecks.

The request for naval contributions has produced mixed responses: a number of countries said they were evaluating the situation or coordinating with the United States, while London, Tokyo and Seoul framed decisions as contingent on technical, legal and security assessments. The episode has widened transatlantic and regional diplomatic debates over burden-sharing, rules of engagement and the risks of military escalation in a narrow, commercially vital waterway.

Market strategists warn that the longer the strait remains effectively closed, the greater the chance of a sustained supply shock feeding into oil prices, insurance premia and freight costs; conversely, a credible multinational security arrangement or rapid de-escalation would be expected to ease the most acute pressures, though residual volatility could persist while commercial flows normalize. Investors are watching shipping data, OPEC+ supply decisions and diplomatic developments for clues on timing and magnitude of any market correction.
