UK Economy Grows 0.7% in Q3 Despite Energy Price Shock — But Oil and Rates Are Doing the Steering

Q3 GDP hit 0.7%, beating the OBR's annual forecast pace, but the growth engine is running on fumes: oil above $100, petrol at £1.70/L, and the BoE just hiked to 4%. The question is how long consumers absorb the hit.

The UK economy expanded 0.7% in the third quarter, matching City expectations and confirming that households and businesses continued spending despite a brutal energy price environment. The Office for National Statistics attributed much of the friction to surging petrol, diesel, and natural gas costs following the re-escalation of the Middle East conflict. Oil prices spent weeks above $100 a barrel through September and into November, while natural gas prices sat at roughly three times their pre-Iran-attack February levels.

September itself delivered 0.2% month-on-month growth — a modest tailwind for Chancellor John Healey — though the ONS revised August's growth from 0.1% down to zero, tempering the good news. Economists had expected flat September output, so the beat is real but small. The Office for Budget Responsibility's November budget forecast of 1.2% annual growth now looks conservative. Growth is running ahead of expectations, which in normal times would be unambiguously good news. But the composition matters: this is an economy growing despite a terms-of-trade shock, not because of favourable conditions. UK petrol has breached £1.70 a litre; diesel is approaching £2. Those prices function as a regressive tax on every household and logistics chain in the country. The Bank of England responded last week with a quarter-point hike to 4%, its latest move to cool inflation that has been driven overwhelmingly by energy costs rather than demand-pull dynamics. This is the central tension: monetary policy is tightening to fight inflation caused largely by a geopolitical supply shock, not by an overheating domestic economy. Households pay twice — once at the pump, once through higher mortgage and borrowing costs. Oil prices have dropped in recent days, offering potential relief, but the damage from months above $100 is already baked into consumer prices, business costs, and inflation expectations. Natural gas at triple pre-conflict levels means winter heating bills will reinforce the squeeze even if crude moderates. The structural picture is an economy that is resilient in the statistical sense — GDP is growing — but increasingly fragile in the distributional sense. Growth is accruing while real household purchasing power erodes. The OBR's optimistic forecast being outpaced does not mean the average household is better off; it may simply mean nominal activity is being inflated by higher prices flowing through the system. The next quarter will test whether this resilience holds. If oil stays below $100 and gas prices moderate, Q4 could surprise to the upside. If the Middle East conflict re-escalates or winter demand spikes gas prices further, the Bank of England faces an ugly choice between fighting inflation and protecting growth — and households bear the cost either way.
