The G7 foreign ministers’ statement on Friday, 21 March, is as much a markets signal as a diplomatic line in the sand. It condemns Iran’s attacks, cites UN Security Council Resolution 2817, and prioritises safe passage through the Strait of Hormuz and stable energy markets. Crucially, it references the International Energy Agency’s 11 March decision to tap emergency reserves to support supply. For investors, that’s a coordinated attempt to cap the risk premium building in oil and gas. (gov.uk)

Why the focus on Hormuz? Because the numbers are unforgiving. In the first half of 2025, about 20.9 million barrels per day transited the strait - roughly a fifth of global petroleum liquids consumption - with more than 20% of global LNG also moving through, largely from Qatar. Bypass pipelines in Saudi Arabia and the UAE can shift only a fraction of that, around 4.7 million barrels per day at best. Any prolonged disruption therefore reverberates well beyond the Gulf.

The price action tells the story. Brent crude has been swinging in double‑digits: it briefly touched about $119 per barrel on Thursday, 19 March, after spiking above $106 earlier in the week, before easing back as traders weighed policy support against physical bottlenecks. Volatility is a feature, not a bug, until shipping lanes clear and physical supply normalises. (apnews.com)

Gas has felt the shock too. On 2–3 March, European benchmark prices jumped by as much as 40–45% after QatarEnergy temporarily halted LNG production and later declared force majeure on some deliveries - a reminder that Hormuz risk is about molecules as much as barrels. Spot spikes cooled, but the fragility is plain. (euronews.com)

Insurance is the other pressure point. War‑risk cover for voyages in and around the Gulf has been repriced sharply, with seven‑day premiums in the Middle East Gulf reportedly rising to multi‑million‑dollar territory per call, while underwriters continue to offer cover but at materially higher rates. Lloyd’s List has also tracked a queue of containerships waiting near the Musandam Peninsula, underscoring operational risk on top of price risk. (lloydslist.com)

Set against that, the IEA’s coordinated stock release - up to 400 million barrels, the largest on record - is designed to smooth supply and temper extreme price moves while flows remain constrained. Releases buy time; they don’t replace chokepoints. Markets will watch the cadence of drawdowns and the pace at which volumes hit refiners. (iea.org)

For UK households, the immediate buffer is regulatory. Ofgem has already confirmed the energy price cap for 1 April to 30 June will fall by about 7% to £1,641 for a typical dual‑fuel household paying by Direct Debit. That shields bills through the spring quarter; the next cap (for July–September) will be set later in the spring and will reflect wholesale prices seen now. (ofgem.gov.uk)

Inflation is the bridge from commodity screens to the high street. Headline CPI was 3.0% year‑on‑year in January, and the Bank of England expects falling utility contributions to do some of the work in bringing inflation down in H1. The key caveat is imported energy: a sustained Hormuz disruption would slow that progress. The next CPI print (for February) lands on Wednesday, 25 March, and will be parsed for any early spill‑overs. (ons.gov.uk)

For SMEs with Middle East exposure - from chemicals and base‑metals importers to food manufacturers dependent on fertiliser inputs - the squeeze shows up in three places: voyage insurance, freight surcharges and working capital. Cash flow can come under strain quickly if war‑risk premia are passed through by carriers, while longer transit times tie up inventory and receivables. Finance teams should map exposures by lane and supplier, speak early to insurers and brokers about endorsements, and model alternative routings and lead times.

For corporates with significant energy use, the message is coordination, not panic. Fix what you can fix - efficiency measures and demand management - while using the regulated cap window to review hedging policies and procurement for the autumn and winter. If you tender for shipping, insist on transparent escalation clauses for war‑risk and bunker surcharges so you can plan margin protection rather than absorb ad‑hoc fees.

From a macro lens, three trackers matter in the weeks ahead: reported oil and LNG loadings versus seasonal norms; the Brent forward curve shape, which captures how much of the risk premium is near‑dated; and the behaviour of war‑risk premia in marine insurance. If flows through Hormuz improve and insurance cost inflation slows, the IEA backstop should help shift prices from panic to premium. If not, policymakers may need to escalate the toolkit. (eia.gov)

Politically, the G7’s line sits within a wider legal frame: UNSC Resolution 2817 condemns attacks on Gulf states and Jordan and reaffirms freedom of navigation, including through the Strait of Hormuz. That matters for shipowners, charterers and banks setting compliance thresholds while they continue to move cargoes under heightened scrutiny. (documents.un.org)
