UK economic growth slows down as Iran war pushes up energy prices
UK GDP rose 0.4% in Q2, but higher energy prices from the Iran war are expected to weigh on growth later this year.
Intelligence analysis by GPT-5.4 Mini
The UK economy slowed from 0.6% growth in Q1 to 0.4% in Q2, with services and construction still expanding while industrial output stalled. Economists say the energy shock linked to the Iran war could weaken momentum in the second half of 2026.
The UK economy is still moving forward, but slower. Higher gas and power prices from the Iran war are like extra weight on a bike, and that could make it harder to keep going.
Analysis
Iran war
The article frames the UK slowdown as less a collapse in domestic demand than a growing drag from imported energy shocks. Oil and gas prices jumped after Donald Trump’s attacks on Iran, and even though household bills were shielded for a time by the price cap, the effect is now feeding through to consumers and firms.
That matters because energy shocks do not stay in one lane. They show up first in utility bills, then in operating costs, then in inflation, and finally in slower spending if households feel squeezed. The piece suggests the UK has coped better than feared so far, but the lagged effects are still arriving.
0.4%
The second-quarter GDP figure is modest but important: it shows growth still exists, but the pace is softer than in the first quarter. Services and construction kept moving, while industrial production was flat, which means the economy’s better-performing parts are doing the heavy lifting.
There is also a one-month wrinkle in the data. June came in stronger than expected, helped by warm weather and World Cup-related spending, which tells a familiar story about temporary boosts masking underlying fragility. That kind of support can make a quarter look sturdier than it really is.
John Healey
The political pressure now lands on John Healey, who is preparing his first budget later this year. The article makes clear that he inherits a difficult mix: higher energy costs, a likely rise in inflation, and businesses warning about a "cocktail" of cost pressures.
That leaves the government with a narrow balancing act. It can try to cushion households and firms, as Andy Burnham wants through lower electricity VAT, but any support has to fit alongside a broader fight against inflation and the risk of higher interest rates. The article’s underlying message is that resilience today may not guarantee resilience through winter.
Key points
- UK GDP grew 0.4% in the three months to June, down from 0.6% in the first quarter.
- Services output rose 0.5% and construction rose 0.3%, while industrial production was flat.
- Economists say higher energy prices tied to the Iran war are likely to weigh on growth later in 2026.
- Inflation is expected to rise again next week, which could increase pressure for higher interest rates.
The UK economy still managed to grow in the second quarter, which suggests it has some resilience even with higher energy costs. If energy pressure eases, the services and construction sectors could help keep growth positive.
The article warns that momentum is likely to fade as higher utility bills and business costs work through the economy. If inflation rises again, the Bank of England could face more pressure to raise interest rates, which would add another brake on growth.
Market signals
- OIL The article says oil and gas prices shot up after the attacks on Iran, which points to firmer crude prices.
