LONDON, April 20, 2026, 09:34 BST
The FTSE 100 slipped early Monday, pulled lower by fresh U.S.-Iran tensions that pushed oil up and rattled risk sentiment across Europe. Energy stocks managed to cushion some of the drop. According to delayed LSEG figures, the UK’s main benchmark was down around 0.6% to near 10,606. France’s CAC 40 slid about 1.3%, while Germany’s DAX fell 1.5%.
The FTSE 100’s heavy tilt toward energy names means big moves in oil can prop up the index, even if pricier fuel stings the broader economy. On Monday, energy stocks across Europe climbed 1.9%. Travel and leisure names, however, dropped 2%, and banks slipped 1.8% as traders reacted to renewed inflation jitters and tighter credit worries.
Friday brought a sharp shift. The FTSE 100 finished 0.7% higher at 10,667.63, as Iran’s assurance about keeping the Strait of Hormuz open through the ceasefire pushed oil below $90 a barrel. That optimism didn’t last: Washington’s seizure of an Iranian cargo ship and Tehran’s rejection of further talks before the truce ends erased earlier gains.
Brent crude shot up $5.51 to $95.89 a barrel by 0752 GMT, paring back after Friday’s sharp 9% fall. The focus has swung once again to the Strait of Hormuz—a narrow passage that handles roughly a fifth of global oil shipments and now sits squarely in the market’s sights.
Charu Chanana, Saxo’s chief investment strategist, pointed to the weekend’s escalation as reviving a conflict premium—higher oil prices now reflecting what she called a “growth-and-rates story.” Pepperstone’s research head Chris Weston described the initial selling as “orderly rather than indicative of a major volatility shock.” Reuters
Britain’s grappling with that right now. Last week, IMF chief economist Pierre-Olivier Gourinchas flagged a higher outlook for UK core inflation, saying the Fund expects it around 2.7% in 2026—up from the 2.2% it projected back in January. He also pointed out the UK’s lingering vulnerability to elevated gas prices.
Britain’s economy posted a 0.5% gain in February, outpacing forecasts, according to official data released Thursday. Still, the support looks fragile. Fergus Jiminez-England at the National Institute of Economic and Social Research said the recent energy shock had “pulled the rug on this momentum,” flagging the likelihood of another year with inflation above target and a weaker jobs market.

Investors have been here before. On April 14, BP flagged “exceptional” first-quarter trading results, while Shell, according to Reuters, also pointed to robust oil trading—both moves that tend to cushion London’s two big names, and by extension the FTSE, when crude prices jump. Reuters
The hedge only goes so far. On Monday, Europe’s travel stocks slid 2%, with banks losing 1.8%. UK 10-year yields climbed roughly 4 basis points, according to Reuters market data. If the Strait remains closed off or negotiations stall before Tuesday’s ceasefire deadline, a firmer oil price could hit consumers and maintain the squeeze on rate-sensitive equities. “The immediate focus was on oil and supply shortages driving inflation,” said Bob Savage, head of markets macro strategy at BNY.
