FTSE 100 Declines as Geopolitical Tensions and Economic Data Dampen Sentiment
Stock prices in London ended the week in negative territory on Friday, March 13, 2026, with the FTSE 100 Index closing down 44.00 points, or 0.4%, at 10,261.15. The broader FTSE 250 Index fell 97.64 points, or 0.4%, to 22,071.10, while the AIM all-share index dropped 7.64 points, or 1.0%, to 759.38.

Geopolitical Uncertainty and Economic Headwinds Drive Market Volatility
Investor confidence was rattled by ongoing developments in the Middle East, particularly concerning the Strait of Hormuz, a critical chokepoint for global oil shipments. US President Donald Trump expressed confidence in potential regime change in Iran following military strikes, but acknowledged it might not occur immediately, adding to market jitters. European nations, including France and Italy, have initiated talks with Iran to secure safe passage through the strait, though no European navies are currently escorting ships due to fears of escalation. UK officials confirmed that Britain is not involved in these discussions.
Meanwhile, economic data from the UK disappointed, with gross domestic product showing no growth month-on-month in January 2026, following a 0.1% rise in December and 0.2% in November. This stagnation, against expectations of 0.2% growth, raised concerns about the UK's economic resilience amid rising energy prices and geopolitical risks. Deutsche Bank analyst Sanjay Raja warned that higher oil and gas prices could squeeze disposable incomes, constrain spending, and dampen investment, further dragging on growth.
Global Market Movements and Currency Fluctuations
European equities also faced pressure, with the CAC 40 in Paris closing down 0.9% and the DAX 40 in Frankfurt ending 0.6% lower. In the United States, stocks were lower, with the Dow Jones Industrial Average down 0.1%, the S&P 500 index 0.4% lower, and the Nasdaq Composite falling 0.8%. US GDP growth for the fourth quarter of 2025 was revised down to 0.7% on an annualised basis, marking the weakest reading since early 2025.
Currency markets saw the pound fall to 1.3233 dollars from 1.3353 dollars, while the euro declined to 1.1437 dollars from 1.1522 dollars. The dollar strengthened against the yen, trading at 159.58 yen compared to 159.21 yen. Brent oil prices rose to 101.57 dollars a barrel from 98.65 dollars, reflecting supply concerns linked to Middle East tensions.
Sector-Specific Performances and Corporate Updates
In London, mining stocks weighed heavily on the FTSE 100, with Fresnillo ending 6.2% lower, Antofagasta down 5.5%, and Anglo American losing 2.4%. Conversely, Admiral shares climbed 1.9% after RBC upgraded its rating to "outperform" and increased its price target. Berkeley Group shares fell 1.5% as the company reaffirmed its profit forecast but highlighted risks from the Middle East conflict potentially worsening macroeconomic conditions.
On the FTSE 250, Trainline led gains with a 6.9% bounce back after previous losses. Among small caps, Catenai jumped 14% following an investment in AI technology, while BSF Enterprise plunged 51% after terminating a fundraise plan. Gold prices fell to 5,043.40 dollars an ounce from 5,131.30 dollars.
Outlook for the Coming Week
Looking ahead, central bank meetings are set to dominate the financial calendar, with rate holds anticipated in the US, Japan, the UK, the eurozone, Canada, and Switzerland. Economic data releases include US industrial production figures on Monday. In the UK corporate sphere, full-year results are expected from Standard Life, Marshalls, and SigmaRoc, which could provide further insights into sectoral health amid ongoing economic and geopolitical challenges.
