Oil shipments through the Strait of Hormuz have mostly come to a halt. OPEC+ members say they can't lift exports while the Iran war paralyse transit.
Record drain on global supply
Industry reports say global oil flows have faced their biggest disruption ever, cutting 12 to 15 million barrels a day from the market. That's roughly up to 15% of global supply — a shock of a scale few in the market have seen outside wartime scenarios.
The immediate consequence has been a sharp rise in crude prices. Traders pushed U.S. West Texas Intermediate (WTI) futures sharply higher for May delivery, with WTI closing at $111.54 per barrel after an 11% intraday jump. Brent, the international benchmark, ended the session at $109.03, up almost 8% on the day.
Higher oil prices quickly affect the economy. Oil is the feedstock for transport, electricity generation and many industrial processes; when crude spikes, costs seep into everything from filling stations to fertiliser, clothing and plastics, according to background material on the oil sector.
Why paper increases won't fix flows
OPEC+ ministers are due to discuss quotas for May at a meeting on Sunday. Several sources within the alliance told reporters that the group may approve an output increase.
But if the recent weeks are any guide, that will be largely a paper exercise: the states that could actually raise crude output — Saudi Arabia, the United Arab Emirates, Kuwait and Iraq — have seen exports slashed because the Strait of Hormuz has been effectively closed since late February.
Damage to oil infrastructure inside the Gulf from missile and drone strikes has been heavy. Gulf officials have warned it will take months to restore normal operations even if hostilities cease and Hormuz reopens immediately. And some OPEC+ participants can't lift output for other reasons: Russia, for instance, faces Western sanctions and production constraints tied to damage from the war in Ukraine.
The main point is that increasing quotas won’t boost output until the chokepoint reopens and damaged facilities get fixed.
How OPEC+ fits into the squeeze
OPEC — the Organisation of the Petroleum Exporting Countries — and its wider alliance OPEC+ together account for a large slice of global oil production. The cartel's members control a big share of proven reserves, and OPEC countries alone produce about 40% of the world's crude, with member exports accounting for roughly 60% of international petroleum trade, according to background material on the organisation.
OPEC was created in 1960 to coordinate oil policies among producers. In 2016 it created OPEC+ by formalising cooperation with around 10 non‑OPEC producers, including Russia, to better manage supply and stabilise prices. The current crisis, though, shows the limits of policy coordination when physical export routes are closed or facilities are under attack.
Energy consultancy Energy Aspects called any planned increase 'academic' as long as Hormuz stays blocked, highlighting the gap between decisions in Vienna and actual oil deliveries.
Market signals and downside risks
The market has already factored in significant strain. Crude at over $100 a barrel is a multi‑year high; some analysts warned prices could climb far higher if the chokepoint stays shut. One major bank said prices might break above $150 a barrel if flows through Hormuz aren't restored before mid‑May — a scenario that would set new records for the oil age.
Traders are responding to both the supply hit and the uncertainty. Volatility has returned to oil markets after a period of relative calm. That matters for governments and businesses that manage budgets and hedges around expected fuel costs. Companies that use a lot of energy and countries reliant on oil imports face harder choices on spending, pricing and inflation management.
What it means for the United Kingdom
The UK isn't an OPEC member. But British households and businesses are still exposed. Oil feeds into transport fuel, building materials and fertiliser — imported goods and domestic services will face higher input costs if crude stays elevated. That puts upward pressure on the retail price of petrol and diesel, and on the bills of firms that rely on road haulage and manufacturing, as the background briefing on oil's uses explains.
Still, the UK benefits from a diversified energy mix compared with some countries, and retail fuel prices are influenced by taxes, refining margins and local distribution as much as by the crude price at the port. Policymakers in London will be watching wholesale markets and assessing whether any emergency measures are needed to shield vulnerable households or key industries from sharp shocks.
At the same time, sustained high oil could make the Bank of England's inflation outlook. Higher energy and transport costs feed into headline inflation readings, and central bankers factor commodity swings into rate decisions. If oil adds fresh upward pressure to prices, that could affect the timing and scale of monetary moves — which in turn plays through to mortgages, business borrowing and the wider economy.
Diplomacy, infrastructure and the long repair job
Opening Hormuz again requires two things: a reduction in attacks on shipping and facilities, and time to repair damage. Gulf officials have warned repairs could take months even in the best case. Repair crews need secure access, specialist parts and time — none of which can be conjured overnight.
Diplomacy is just as crucial as technical repairs now. Restoring the flow of oil will need both a ceasefire‑type agreement to limit strikes and a concerted, co‑ordinated effort by producers and service companies to rebuild capability. Until that happens, OPEC+ decisions on quotas will have at best a signalling value: they show readiness to add supply later, not an immediate fix for missing barrels.
Where things stand now
OPEC+ agreed a modest output boost of 206,000 barrels per day for April at its March meeting — a figure set before the recent sharp escalation. Ministers will revisit quotas for May at their Sunday meeting. Any new figure will be watched for its tone as much as its number: a big increase could be intended to calm markets, even if it can't be implemented right away.
Energy market watchers say the key variables are the pace of repair in the Gulf, whether shipping lanes can be reopened safely, and how resilient inventories and non‑OPEC producers prove to be. The sheer scale of the current disruption, however, means that normalisation — if it happens — could take weeks or months rather than days.
