Fresh geopolitical turmoil in the Middle East has reignited fears of a closure of the Strait of Hormuz, the narrow waterway through which roughly one-fifth of the world's oil passes. The trigger for the latest escalation remains unclear, but shipping sources confirm that several tankers have been diverted and insurance premiums for vessels in the region have tripled overnight. For UK motorists and households, the immediate consequence is likely to be a sharp rise in fuel and heating costs, just as inflation had begun to ease.
Brent crude futures jumped more than 6% on Monday, trading above $95 a barrel, before settling at $94.70. Analysts at Capital Economics warned that a full blockade could push prices past $110, a level not seen since the 2022 energy crisis. 'The Strait handles about 17 million barrels per day. Even a partial disruption will cascade through global supply chains within days,' said one senior commodities strategist. The UK's reliance on refined products from the Gulf means petrol prices at the pump could climb by 10p per litre in short order.
The FTSE 100 fell 1.8% to 7,210 points by mid-afternoon, as investors fled risk assets. However, the index's energy heavyweights bucked the trend: BP rose 3.2% and Shell added 2.9%, as traders priced in higher margins. Mining stocks and airlines bore the brunt of the sell-off, with British Airways-owner IAG dropping 4.5% on fears of higher jet fuel bills. 'This is a classic flight to safety within the market,' said a London-based fund manager. 'Energy stocks are a hedge, but the broader economy takes a hit.'
The implications for UK pension holders are mixed. Many defined-contribution pension schemes hold significant allocations to BP and Shell, meaning the oil price spike could boost fund values in the short term. However, a prolonged closure would hammer consumer-facing sectors and increase the risk of a recession, dragging down diversified portfolios. The Bank of England, which had been signalling rate cuts later this year, may now face renewed inflationary pressure, complicating its monetary policy path.
Diplomatic efforts are reportedly under way, but no resolution is expected this week. The UK government has not yet announced plans to release oil from the Strategic Reserve, though Downing Street said it is 'monitoring the situation closely'. For now, businesses and households are left to brace for higher costs, with the added uncertainty of how long the strait will remain contested.
