UK and Saudi discuss Strait of Hormuz security
On 24 March 2026, the Prime Minister, Sir Keir Starmer, phoned Saudi Arabia’s Crown Prince Mohammed bin Salman. He opened with Eid greetings and condemned what he described as Iran’s ongoing attacks, including on critical national infrastructure. Both leaders agreed to keep in close contact as events unfold.

Downing Street’s readout says the UK reaffirmed its “unwavering support” for Saudi Arabia, confirmed the deployment of further UK defensive military equipment, and discussed the need for de‑escalation. The Prime Minister also briefed on UK planning around the Strait of Hormuz and on work with partners after a UK‑led joint statement the previous week focused on securing trade routes. (gov.uk)
If you’re hearing “Strait of Hormuz” a lot and wondering what it is, picture a narrow maritime doorway between Oman and Iran - the only sea route from the Persian Gulf to the open ocean. Shipping here follows a traffic‑separation scheme with two roughly two‑mile‑wide lanes, one in each direction, split by a two‑mile buffer. That tight design raises risk when tensions spike.

Why it matters to all of us: in 2023 around 20.9 million barrels per day of oil and petroleum products moved through Hormuz - roughly one‑fifth of global petroleum liquids use and more than a quarter of the world’s seaborne oil trade. Close to a fifth of global LNG trade also transits the strait, much of it from Qatar, and most crude flows are ultimately bound for Asian markets. (eia.gov)
Alternatives exist but are limited. Saudi Arabia’s East–West pipeline to the Red Sea and the United Arab Emirates’ line to Fujairah can bypass Hormuz, yet analysts estimate only a few million barrels per day of effective spare capacity on these routes - nowhere near the 20‑million‑plus that usually passes the strait. That’s why pressure here can move prices worldwide. (eia.gov)
Through mid‑March, independent reporting described the passage as effectively closed at times, pushing up petrol prices and prompting planning for escorted transits and mine‑countermeasures once conditions allow. In such tight waters, even a small number of naval mines is a serious hazard. (apnews.com)
Costs climbed too. Major shipping lines introduced war‑risk surcharges for Gulf voyages, and insurers sharply repriced cover for vessels near Iranian waters in early March. Higher premiums and new conditions add expense to every cargo that tries to move. (hapag-lloyd.com)
A quick media‑literacy note. Phrases like “defensive military equipment” and “planning” are careful choices. They confirm action without naming systems, routes, or timelines - details that can endanger personnel, inflame politics, or change market behaviour. It’s normal not to see model names or destinations in public updates from governments.
What this means for you: even if the UK doesn’t buy much energy directly from the Gulf, global markets set our prices. When a fifth of the world’s petroleum liquids and a chunk of LNG face disruption, the costs of filling up, flying, heating and deliveries can move quickly - exactly what international outlets flagged this month.

What to watch next: a named maritime plan for safe passage, clear rules for any escorts and mine‑clearing, and signs that insurers are restoring affordable cover. The UK says it is working with partners on a viable plan to keep goods moving through this critical route; the test will be whether ships can transit safely. (gov.uk)
