UK Growth Outlook Brightens After US-Iran Truce Lowers Oil Costs

positif

The US-Iran truce has sharply improved UK growth forecasts, with Bloomberg Economics raising its 2026 GDP projection to 1.2% from 0.8%. The deal, which ended Iran's closure of the Strait of Hormuz, has driven oil prices below $80 a barrel after they spiked above $100 in February. This de-escalation is "unequivocally good news" for Britain, as lower energy costs ease inflation and reduce pressure on the Bank of England. Inflation is now expected to stabilize at 3% by year-end, down from a prior forecast of 3.5%, allowing the Bank to hold rates at 3.75%. If Brent crude remains around $70 a barrel, economists say the discussion could quickly shift to further easing, with a final cut to 3.5% possible in Q2 2027. However, growth is still projected to slow to 0.2% per quarter in the second half of 2026, below the 0.6% seen in Q1. Despite the oil-driven boost, domestic politics remain the biggest uncertainty for the UK economy. Incoming Prime Minister Andy Burnham has pledged more social housing and cost-of-living support, raising fiscal concerns among markets already nervous about the UK's debt plans. While falling energy prices soften the slowdown, the political landscape could undermine the recovery if spending commitments spook investors. What to watch next: Whether Brent crude prices hold below $80 a barrel and how markets react to Andy Burnham's fiscal policy announcements after he takes office in mid-July.

The fall in global oil prices is “unequivocally good news” for Britain’s economy, Bloomberg Economics said as it lifted growth forecasts for this year.

UK output will expand 1.2% in 2026, it said, up from a forecast of 0.8% before the US and Iran struck an interim peace deal. The latest official growth figures for the three months to March are due to be published on Tuesday morning.

Inflation is now expected to stabilize at 3%, below the 3.5% that Dan Hanson’s team had been projecting by the year end.

With the threat from inflation receding, the Bank of England will be able to hold interest rates at 3.75% so long as oil prices do not spike again, the economists said. If Brent crude remains at current levels of just above $70 a barrel “the discussion could quickly flip to the timing of further easing.”

Bloomberg Economics sees “a final cut” to 3.5% in the second quarter of 2027, with inflation averaging 2.3% across next year.

The conflict in the Middle East that began on Feb. 28 derailed growth across the world when Iran closed the Strait of Hormuz, causing a bottleneck in oil supplies. Prices rose above $100 a barrel, raising fears of another inflation shock and hit to growth — particularly in the UK.

Recent de-escalation has brought prices below $80 a barrel despite skirmishes that are testing the deal agreed between Iran and the US earlier this month. Gas prices have also fallen.

Bloomberg Economics said the UK economy is likely to grow at 0.2% over each of the remaining quarters of this year, down from 0.6% in the first three months and still lower than its 0.3% estimate of trend growth.

While falling oil and gas prices are promising, the UK faces another risk in the incoming Prime Minister Andy Burnham, who has promised more social housing and help for families with the cost of living at a time when markets are nervous about the UK’s fiscal plans. Burnham is expected to take office in mid-July.

“Growth is still likely to slow in the second half of the year but the cooling will be less marked than it otherwise would have been,” said Hanson, Matt Bunny and Ana Andrade, economists at Bloomberg Economics. “Domestically, politics remains the biggest uncertainty.”
