(Alliance News) - Stock prices in London closed mostly lower on Monday, after a busy day for those observing the Middle East conflict with oil prices staying above the USD100 mark.
"Earlier today it looked like we were poised for a fresh outbreak of risk aversion as Brent pushed through the magic USD100 level," IG's Chief Market Analyst Chris Beauchamp said. "Stock markets stand or fall by the oil price at present, and in the topsy-turvy world created by the war against Iran, the absence of bad news, and hopes that the war will last weeks rather than months, is enough to prompt a recovery in equities."
NATO and other Western allies pushed back Monday on US President Donald Trump's demand that military alliance members help reopen the Strait of Hormuz, the critical conduit for crude oil that Iran has effectively closed.
UK Prime Minister Keir Starmer said London was working with allies to craft a "viable" plan to reopen the strategic waterway but ruled out a NATO mission, while Berlin insisted it was "not NATO's war". Spain, Japan and Australia were among other nations to distance themselves from any military involvement in the Strait of Hormuz in the wake of Trump's call.
Further, Ukraine's Volodymyr Zelensky will visit the UK on Tuesday as Starmer warned the oil price rises caused by the Middle East crisis could result in a "windfall" for Russia's economy.
Meanwhile, Iran said it was ready to take the Middle East war "as far as necessary" as it launched strikes across the region on Monday.
The FTSE 100 index closed up 56.54 points, 0.6%, at 10,317.69. The FTSE 250 ended down 48.63 points, 0.2%, at 22,022.47, and the AIM all-share closed down 5.12 points, 0.7%, at 754.26.
The Cboe UK 100 was up 0.6% at 1,025.20, the Cboe UK 250 was down 0.4% at 19,240.41, and the Cboe small companies was down 0.5% at 17,513.39.
Gold miners and defence stocks were among the large-cap winners as geopolitical tensions mounted. Endeavour Mining gained 3.1%, Melrose rose 1.4%, Rolls-Royce 1.2% and Fresnillo 0.7%
However, gold was quoted lower at USD4,983.55 an ounce against USD5,043.40.
Oil major Shell was up 1.4%, while BP gained 1.5%.
Brent oil was higher at USD102.83 a barrel around the time of the London equities close on Monday from USD101.57 late Friday, although it was quoted at USD106.09 a barrel near the London open.
"Just as equity traders find themselves trading and watching oil, commodities traders are now transfixed by the movements of individual ships through Hormuz," IG's Beauchamp said. "A second week where oil fails to hold above USD100 might start to suggest that investors are still happy to sell the rallies in Brent and WTI on the basis that the US will take steps to prevent Iran closing the strait on a permanent basis."
International Energy Agency chief Fatih Birol has said that more strategic oil stocks could be released if necessary, to limit the fallout of from the near complete blockage of supplies through the Strait of Hormuz.
Still, he added that further releases of stocks could only constitute a "buffer" against the current choking off of supplies, and are "not a lasting solution".
"The single most important thing for a return to stable flows of oil and gas is the resumption of transit through the Strait of Hormuz," Birol said.
As for airlines, easyJet was among the worst FTSE 100 performers with a 1.8% fall, while on the FTSE 250 Wizz Air lost 2.9%.
On AIM, meanwhile, Botswana Minerals gained 23%.
The copper and diamond explorer, previously known as Botswana Diamonds, said its pretax loss narrowed to GBP215,000 for the six months to the end of December, and that it had consolidated its position as a "technology-enabled explorer in Botswana".
It added that "in response to prolonged weakness in the natural diamond market and the structural rise of lab-grown diamonds, we have prioritised capital allocation towards copper and other critical minerals where demand fundamentals are robust."
CPPGroup, meanwhile, fell 29%.
The digital financial services provider reported that OneAssist Consumer Solutions Private does not expect to pay any deferred consideration, which is contingent on agreed performance conditions, for its purchase of CPP India last year.
CPPGroup said that if the deferred consideration is not paid, it will require additional funding within the next 12 months.
