Stronger UK GDP growth lifts London stocks despite rising geopolitical and energy market tensions.

The FTSE 100 opened at 10,621.79, up 12.87 points or 0.1%, while the FTSE 250 rose 0.1% to 23,901.65 and the AIM All-Share gained 0.8% to 788.70.
The UK economy expanded 1.6% year over year in July, its fastest annual growth rate since February 2025; sterling also rose 0.09% against the U.S. dollar to $1.3524.
Iran’s Revolutionary Guard said its navy had struck a U.S. “Saildrone-type” unmanned vessel in the Strait of Hormuz, claiming it had “thwarted its aggressive mission.” Ship-tracking data showed seven vessels transited the strait on Thursday, compared with 11 the previous day and a 10-day average of 15.
The International Atomic Energy Agency accused Iran of “noncompliance” with its nuclear non-proliferation commitments and referred the matter to the UN Security Council; Iran’s UN envoy Gholamhossein Darzi called the accusations “political and not technical in nature.”
Within manufacturing, electronics, pharmaceuticals and basic metals supported output, while continued weakness in mining and quarrying weighed on the broader production sector.
London stocks edged higher as the UK economy delivered stronger-than-expected growth, providing a lift to the FTSE 100 and broader European markets. UK GDP rose 0.4% month over month in July, beating forecasts and marking the eighth consecutive period of expansion, though gains were tempered by geopolitical tensions in the Strait of Hormuz and uncertainty ahead of U.S. inflation data. London Insider reported that the FTSE 100 rose 87 points to 10,695, while Share Talk showed the index closed 0.39% higher at 10,650.44.
The FTSE 250 gained 0.38% to 23,975.73 and the AIM All-Share rose 0.8% as services-sector expansion drove the broader economic recovery. UK annual growth reached 1.6% in July—the fastest rate since February 2025—with artificial intelligence and cloud-related technology services posting notable gains. Production and construction both declined, however, and elevated oil prices plus Middle Eastern tensions kept investor enthusiasm in check.
The UK economy expanded 0.4% month over month in July after 0.3% growth in June, with the services sector providing the primary engine. Three-month growth stood at 0.4%, maintaining the nation's streak of consecutive quarterly expansion. Output in artificial intelligence and cloud-related technology services increased, signaling strength in high-growth sectors that are reshaping the economy.
Within manufacturing, electronics, pharmaceuticals and basic metals supported output, though continued weakness in mining and quarrying weighed on the broader production sector. ShareCast noted that the GDP reading boosted rate hike bets after the latest U.S. inflation print, reshaping expectations for central bank policy across both the Atlantic.
Sterling rose 0.09% against the U.S. dollar to $1.3524 following the strong UK growth data, reflecting investor confidence in the domestic economy. The annual growth rate of 1.6% marked the fastest pace since February 2025, providing a tailwind for the pound. However, the UK's trade deficit narrowed over the latest three-month period as exports and the services surplus strengthened, despite higher goods imports—a mixed signal on broader competitiveness.
The Strait of Hormuz remained a flashpoint as Iran's Revolutionary Guard claimed to have struck a U.S. 'Saildrone-type' unmanned vessel, calling it a success in 'thwarting its aggressive mission.' Ship-tracking data showed only seven vessels transited the strait on Thursday—down from 11 the previous day and well below a 10-day average of 15—signaling disruption concerns that kept oil prices elevated.
The International Atomic Energy Agency accused Iran of 'noncompliance' with non-proliferation commitments and referred the matter to the UN Security Council. Iran's UN envoy Gholamhossein Darzi dismissed the accusations as 'political and not technical in nature.' These escalations underscore the geopolitical risks weighing on European markets despite positive domestic data.
European markets closed higher as oil prices fell sharply following the International Energy Agency's downward revision to global oil demand forecasts and prospects of Gulf foreign minister talks. Yahoo Finance and NASDAQ both reported the rally, with falling crude providing relief after weeks of elevated prices tied to Middle Eastern tensions.
Still, major European indexes remained little changed to modestly higher as investors weighed the upbeat UK domestic data against lingering geopolitical and energy-market risks. ShareCast reported that stocks saw a surge as UK GDP beat forecasts and oil prices eased, though U.S. inflation uncertainty kept broader optimism in check.
