Crude oil prices have tumbled to levels not seen since before the Iran crisis, handing UK drivers a rare moment of relief at the petrol station. Brent crude dipped below $75 a barrel on Tuesday, a far cry from the $120 peaks that followed the escalation in the Strait of Hormuz. For the Treasury, this is a double-edged sword: falling petrol prices ease the cost of living squeeze, but they also signal a global demand shock that could destabilise the Chancellor’s fiscal arithmetic.
Market fundamentals are punishing the speculators who bet on sustained conflict. The reality is that global oil inventories have swelled as the US shale machine roars back to life and Saudi Arabia floods the market. The Iran premium, always a fragile construct, has evaporated. Investors are now pricing in a recession risk that makes oil demand look shaky. The London bourse saw BP and Shell slip as traders rotated out of energy into defensive stocks.
For the average motorist, the pain at the pump is easing. Average petrol prices in the UK have fallen from 152p to 141p per litre in a month. That is a welcome injection of disposable income for households squeezed by mortgage rates and food inflation. But do not mistake this for a policy victory. This is market forces at work, not some clever government intervention. The fuel duty cut introduced by Rishi Sunak remains a permanent drag on the public finances that should have been reversed when oil was high.
The Bank of England will watch this closely. Lower oil prices suppress headline CPI, but they also reflect weaker global trade. The MPC may find itself cutting rates sooner than expected to stave off a downturn, but that would reignite inflation in the services sector. The pound’s modest rally against the dollar, driven by falling energy import costs, offers some comfort. Yet capital flight from UK equities continues as investors seek refuge in US tech and European bonds.
The real question is whether this oil price decline is sustainable. Supply disruptions from Iran are off the table, but the Russia-Ukraine war still caps supply. Opec plus could cut output again to prop up prices, but Saudi Arabia needs a high break-even price for its Vision 2030 spending. If oil stays low, the kingdom may face a budget crunch, which would ripple through global markets.
For now, enjoy the cheaper petrol. But remember: the market giveth and the government taketh away. If oil stays low, the Chancellor will be tempted to raise fuel duty in the Autumn Statement. So fill up the tank and count your blessings while they last.
