Oil jumps: markets unconvinced by Trump’s plan to reopen Strait of Hormuz

Oil prices moved higher amid a renewed risk-off tone as markets signaled skepticism about President Trump’s pledge to reopen the Strait of Hormuz. Traders cited ongoing disruption to shipping and limited near-term options to offset lost flows as drivers of the rally.

The episode intensified after White House comments about building an international naval presence to secure transit and reports that the U.S. had asked allies to contribute ships; those remarks did not reassure traders that traffic would quickly normalize. Parallel initiatives — including offers of maritime political-risk insurance and reinsurance mechanisms aimed at keeping cargo moving — were announced but market participants treated them as insufficient to eliminate immediate supply fears.

The immediate market reaction was classic risk-off: energy names outperformed while broad equity benchmarks softened as investors priced in a higher energy risk premium. Crude benchmarks saw notable gains on the session, reflecting both the physical disruption in the Gulf and a premium for potential escalation. Fixed-income and safe-haven assets registered flows consistent with elevated geopolitical uncertainty.

The strategic importance of the Strait of Hormuz — a chokepoint for a meaningful share of seaborne oil trade — means any sustained restriction can rapidly translate into global price pressure. The U.S. Energy Information Administration (EIA) in its short-term outlook flagged that continued flow disruptions would keep Brent prices elevated in the near term, complicating the inflation outlook and central bank policy calibration.

Market strategists say the likely path is heightened volatility in oil markets with episodic spikes tied to operational and diplomatic developments. Near-term scenarios include partial rerouting, temporary insurance schemes, or coordinated naval escorts, but analysts stress that the duration of disruptions is the key determinant of how large and persistent the price impact will be. Traders will be focused on tanker movements, insurance premia, producer shutdowns and diplomatic progress for signals on whether the current risk premium will fade or intensify.
