Downing Street said Prime Minister Keir Starmer spoke with Bahrain’s Crown Prince Salman bin Hamad Al Khalifa on Friday, 21 March, outlining fresh UK support including a counter‑drone team. Both condemned Iran’s attacks on critical infrastructure and the Strait of Hormuz; the PM also noted US use of UK bases for defensive operations against missile sites threatening commercial shipping. For markets, the message is clear: energy and maritime risk remains live. (gov.uk)

Why this matters for prices and portfolios is straightforward. The Strait of Hormuz carries around 20 million barrels per day of oil-about a fifth of global petroleum liquids-and roughly one‑fifth of global LNG. Spare overland workarounds via Saudi Arabia’s East–West line and the UAE’s Habshan–Fujairah pipeline cover an estimated 3.5–5.5 mb/d at best, insufficient to offset a prolonged closure. Bahrain also hosts the UK Naval Support Facility at Mina Salman, a logistics hub for Gulf operations. (eia.gov)

Prices have responded. Brent crude pushed back above $100 and settled near $112 on Friday, 20 March, after spiking as high as $119 earlier in the week as conflict headlines intensified. Volatility is dictating intraday swings, and the risk premium is now doing real work in energy equities and broader indices. (apnews.com)

Cover is getting pricier and, in places, constrained. Several marine insurers moved to cancel Gulf war‑risk policies from 5 March, forcing owners to renegotiate terms when approaching the high‑risk zone. Hapag‑Lloyd has introduced a $1,500 per‑TEU war‑risk surcharge on Middle East Gulf cargoes, with similar levies elsewhere. Lloyd’s of London says the market remains open to insure hull and cargo transiting Hormuz, albeit at sharply higher rates; in isolated high‑risk cases, brokers told Lloyd’s List that quoted hull war‑risk premia have jumped ten‑fold to the mid‑single digits or more as a share of hull value.

Freight and flows are stalling. Maersk and CMA CGM have suspended Hormuz transits, while Lloyd’s List counted dozens of container ships idling near the Musandam Peninsula as services divert via the Cape of Good Hope-adding weeks to schedules and ratcheting up fuel and charter costs that are already feeding through to quotes.

Gas isn’t immune. European benchmark TTF jumped towards €70/MWh on 9 March as traders priced fewer Qatari cargoes and longer voyages. For UK households, Ofgem’s price cap still falls 7% on 1 April to £1,641, but sustained crude above $100 risks firmer pump prices and a slower disinflation path; RAC‑tracked data already show early‑March rises at the forecourt.

Sector lens. Defence names have outperformed on expectations of sustained orders and higher readiness spend, with BAE Systems among European movers; but for specialty insurers any short‑term repricing tailwind in marine war‑risk is offset by the threat of large claims if hostilities persist. Barclays flags Hiscox, Lancashire and Conduit as relatively more exposed lines by premium mix. (investing.com)

Policy watch. The UK has authorised US use of specific British bases for defensive operations against Iranian missile sites; the permanent Royal Navy hub in Bahrain underpins logistics for Gulf security. Friday’s call underscores an intent to reduce maritime risk, not elevate it-but markets will keep charging a premium until normal transit resumes. (apnews.com)

What could ease the strain? Three things to track this week: credible, escorted corridors for merchant shipping; evidence of higher utilisation on Saudi and UAE pipelines; and any International Energy Agency‑coordinated stock release. French daily Le Monde reported members preparing a 400‑million‑barrel release-helpful for oil if activated at pace, though LNG routing remains the binding constraint. (lemonde.fr)

Practical take for UK SMEs and finance teams: confirm with forwarders whether bookings are being rerouted and whether war‑risk surcharges are being passed through; extend lead‑time assumptions on Gulf‑exposed inputs; and stress‑test cashflow for fuel and freight volatility while monitoring Brent and TTF closes. The economic story here is human-logistics managers, drivers and crews absorbing another round of uncertainty-so planning buffers matter. (Ofgem’s 1 April cap still lands, but it’s no shield against higher transport and goods costs if disruption drags.) (ofgem.gov.uk)
