The Treasury has fired a warning shot across the bows of British households and businesses: energy prices are set to spike following Iranian military strikes that have severed critical oil supply routes through Kuwait. For a government already haemorrhaging fiscal credibility, this is yet another gale-force headwind.
The disruption began when Iranian missiles targeted key infrastructure in the Gulf, knocking out pumping stations and loading terminals that handle a substantial portion of Kuwait's crude exports. The Strait of Hormuz, that perennial geopolitical tinderbox, remains open for now, but the loss of Kuwaiti capacity has already tightened global supply. Brent crude surged past $95 a barrel in early trading, and analysts are revising forecasts northward with each passing hour.
Chancellor of the Exchequer Rachel Reeves, who has staked her reputation on fiscal discipline, now faces a nightmare scenario. Higher energy costs will feed directly into inflation just as the Bank of England is trying to coax inflation back to its 2% target. The core problem is that this is neither demand-led nor transitory. It is a supply shock, the sort that central banks loathe because it simultaneously depresses growth and raises prices. The Monetary Policy Committee will have to choose between choking off the recovery or letting inflation run hot. Either way, gilt markets will exact a price.
And the gilt market is already restless. The 10-year yield, which had been drifting down from its autumn highs, shot up to 4.35% on the news. This is a signal that investors are demanding a higher risk premium for holding UK debt, and it will soon translate into higher borrowing costs for the Treasury. Given that the Chancellor has already pledged not to raise taxes on 'working people,' the pressure will fall on spending cuts or more borrowing. Neither option is palatable.
For households, the immediate pain will come at the petrol pump and in heating bills. The average price of a litre of unleaded is expected to climb above £1.50 within days, adding to the cost-of-living squeeze that has already eroded real incomes. The Office for Budget Responsibility will have to revise its fiscal forecasts, and the Chancellor's headroom against her fiscal rules will evaporate faster than a drop of crude on a hot asphalt road.
The market reaction has been swift. Sterling fell half a cent against the dollar as traders priced in a weaker growth outlook. The FTSE 100, heavily weighted with oil and gas producers, actually rallied, but that is cold comfort for the broader economy. Capital flight is a growing concern. International investors, already wary of the UK's political instability and sluggish productivity, will see this as yet another reason to reallocate funds to more resilient markets like the US or Singapore.
The Treasury's warning is a belated recognition that the UK's energy security has been compromised by years of underinvestment in domestic production and storage. While the North Sea still yields some oil and gas, it is a shadow of its former self. The government's net zero ambitions, laudable as they are, have not been matched by a credible transition plan. Now, we are left exposed to the whims of petrostates and their regional conflicts.
In the City, the mood is grim but unsurprised. We have lived through the 1973 oil shock, the 1990 Gulf crisis, and the 2022 Ukraine invasion. Each time, the lesson has been the same: diversify or pay the price. The Treasury's belated hand-wringing and calls for international coordination are necessary but nowhere near sufficient. What is needed is a clear-eyed strategy to boost domestic energy resilience, which will require investment in nuclear, renewables, and grid infrastructure. But that costs money, and money is precisely what the Treasury does not have.
For now, brace for higher prices, weaker growth, and a more volatile pound. The only certainty is that the Chancellor's budget arithmetic just got a lot uglier.
