London’s FTSE 100 edged down 0.07% to 10,878.12 points on Wednesday, August 26, snapping a six-session winning streak. Healthcare and energy shares weighed on the blue-chip index as investors weighed incoming U.S. inflation data and prepared for quarterly earnings from Nvidia.
FTSE 100 and FTSE 250 Market Movements
The blue-chip index retreated slightly after six straight sessions of gains, pressured by a 1.18% drop in healthcare shares and a 0.67% decline in energy stocks that tracked a softening in global oil prices. At the same time, the midcap FTSE 250 managed a modest gain of 0.17%, supported by strong corporate results in the mining sector.
Sector Pressures and Earnings Watch on London Markets
Market sentiment across London reflected a holding pattern as institutional investors waited for Nvidia’s second-quarter earnings report. Market participants looked to the chipmaker’s figures to gauge whether the artificial intelligence spending boom can sustain lofty valuations. Meanwhile, U.S. inflation data landed largely in line with expectations, reinforcing market bets on a potential Federal Reserve interest-rate hike next month.
Software stocks also faced headwinds in London trading, led by a 3.76% fall in Sage Group, while Experian and RELX recorded declines between 1.22% and 1.4%. On the other side of the ledger, consumer stocks such as British American Tobacco, Imperial Brands, and Unilever edged higher to provide a floor for the main index.
Midcap Mining Gains and Retail Trends
Away from the blue-chip headwinds, the midcap tier found strength in individual corporate reports. Hochschild Mining climbed 5.4% after reporting that its first-half revenue jumped 62% compared to a year ago, placing the miner among the top performers on the FTSE 250 according to Reuters reporting by Anand Gopal with editing by Diti Pujara and Kirsten Donovan.
The broader retail sector also showed signs of cooling off. British retail sales weakened in August following what had been their strongest performance in six months during July.
Broader Economic Outlook and Geopolitical Tensions
Global markets faced additional crosscurrents from geopolitical developments in the Middle East and shifting commodity prices. A senior Iranian official stated that Iran and Oman were working on details of an agreement over the Strait of Hormuz. Meanwhile, global stocks pulled back with the FTSE 100 closing down 17 points at 10,582, while oil surged on news that Iran and the U.S. walked away from peace talks, prompting IG chief market analyst Chris Beauchamp to state that Stocks mostly pull back as the escalation in the Middle East conflict lifts oil prices above $100 per barrel and maintains risks of stagflation.
Thomas Pugh on RSM UK Stagflation Risks
Rising oil prices following U.S. plans to blockade the Strait of Hormuz raised the risk of stagflation in the UK according to economist Thomas Pugh at RSM UK, who noted that the naval blockade means it’s looking inevitable that the UK is in for another bout of stagflation, even if inflation won’t go as high as in 2023.
Pugh added that higher energy costs could push inflation back above 3% while squeezing consumer incomes and business margins, with diesel prices topping £2 a litre, and warned that the shock from high oil prices over a much longer period could tip the UK into recession
if it results in the Bank of England raising borrowing costs.
Pugh also noted that The good news is that the UK economy can cope with energy prices at current levels. Given inflation and energy efficiency improvements, oil prices of near $100pb aren’t nearly as damaging as they were even before the pandemic,
adding that the Bank of England can probably hold fire on interest rate rises if it becomes clear that energy flows are resuming and prices should fall back.
UKMTO Advisory Notice on Strait of Hormuz Maritime Access
By late afternoon, the FTSE cut its losses to within 20 points as oil companies joined heavyweights from other sectors, with defense companies including BAE Systems, Babcock, and Rolls providing a boost as top risers alongside insurer Admiral, which gained over 2.5%, and Sage, London Stock Exchange Group, RELX, and Experian plc performing strongly. Shell was joined by copper miners including Anglo American as the price of the metal spiked. At the other end, utilities and precious metals miners were dominant among fallers, with United Utilities, Severn Trent, and Endeavour Mining down 2.4% to 1.6% as bond yields rose.
The U.S. maritime blockade of Iran and the Strait of Hormuz began and was confirmed by the UK Maritime Trade Operations in an advisory notice to all ships and owners stating that UKMTO have been informed that, effective from 1400 UTC on 13 April 2026, maritime access restrictions are being enforced affecting Iranian ports.
