The oil market has delivered a sharp verdict on the failed Strait of Hormuz attack. Brent crude closed at $72.41 a barrel, wiping out all gains since the Iran conflict escalation began six months ago. For the City, this is not just a price move. It is a reassessment of risk. The premium that investors baked into every barrel, betting on a protracted disruption to Gulf supply, has evaporated. And with it, the case for panic-driven energy policy.
Let me be clear. The government’s recent scramble to shore up the Strategic Reserve, the emergency coal plant contracts, the hurried talks with Norwegian and Qatari LNG suppliers. All of that was priced for a world where the Strait stays hot. Now the market is telling us that world has not materialised. The question is whether Whitehall will listen.
The arithmetic is brutal. At $90 oil, the UK’s energy subsidy bill was set to exceed £40 billion. At $72, that figure falls by a third. The inflation pass-through from fuel costs, which had added 0.8 percentage points to CPI, now reverses. The gilt market is already pricing in a lower peak for Bank Rate. Two-year yields dropped 12 basis points on the news alone.
But here is the rub. The fiscal hawks will smell blood. The Chancellor’s Autumn Statement had pencilled in a windfall tax extension and extra borrowing for energy support. That spreadsheet is now obsolete. Pressure to scrap the levy and return to ‘normal’ taxation will mount. But normal is a fiction. The structural deficit remains. The real choice is between using this reprieve to repair the public finances or to gamble on further easing.
Capital flight has been a quiet obsession of mine. Since the attack, we saw £15 billion in institutional money leave UK equities, fleeing to dollar assets. The retreat in oil could reverse that. Foreign investors who hedged against a UK recession fuelled by high energy costs may now reassess. Sterling gained 1.4% against the dollar in afternoon trading. That is the market’s way of saying ‘we might have overdone the pessimism.’
Yet the lesson of the past five years is that energy markets do not forgive complacency. The Strait of Hormuz remains a chokepoint. Iran’s proxies still have missiles. The price collapse reflects a tactical success in naval interdiction, not a strategic victory. The risk premium will return the moment the next incident occurs.
So what does this mean for the average Briton? Lower petrol prices, certainly. The AAA pump price should fall below 145p a litre by next week. Heating oil users in rural areas will see relief. But the bigger impact is on the mortgage market. If sustained, this oil drop takes the edge off inflation expectations. Swap rates are already falling. That could mean fixed-rate mortgage deals ticking down from current highs of 6.2% to nearer 5.5% by Christmas.
But do not mistake a market correction for a policy triumph. The government’s energy security strategy has been reactive and expensive. The one bright spot is the accelerated North Sea licensing round, which suddenly looks less desperate and more prudent. But the broader lesson is that fiscal discipline and market forces, not Whitehall panic, are the best guarantors of stability.
I will be watching the 10-year gilt yield closely. If it breaks below 4.1%, the bond vigilantes will have called time on the premium for UK risk. That would be the clearest signal yet that the City believes the energy crisis has peaked. For now, the numbers speak for themselves. The bottom line has improved. But the margin for error remains razor thin.
