Lunchtime market roundup: Shares down; oil prices up on Gulf tensions

Blue chip stock indices in London, Paris and Frankfurt were lower at Wednesday midday as heightened US-Iran tensions led to an increase in oil and gas prices; meanwhile it appeared increasingly likely that the European Central Bank will raise interest rates next week.

The FTSE 100 index was down 72.93 points, 0.7%, at 10,716.35. The FTSE 250 was 241.70 points, 1.0%, at 24,279.59, and the AIM all-share was down 7.75 points, 1.0%, at 788.31.

European Central Bank Governing Council member Joachim Nagel indicated that the central bank will raise borrowing costs next week, while fellow member Gabriel Makhlouf said the decision "won't be a surprise", in interviews published Wednesday.

Speaking to Le Monde, Nagel said: "Markets are pricing in a probability of more than 95% that we will raise interest rates at our September meeting, and I would say that the markets have a rather good understanding of how we are likely to respond at this stage."

However, Nagel, who is the Bundesbank president, didn't commit to further moves beyond this month, saying only that "our meeting-by-meeting approach has served us well in the past and will certainly do so in the future".

Brent crude climbed to USD95.06 a barrel at midday Wednesday from USD92.48 late Tuesday.

tougher response to any retaliation.

Iranian state media reported explosions in the country's south, while Iran's Revolutionary Guards later claimed responsibility for a ballistic missile attack on a US base in Jordan. Jordan's military said it intercepted most of the missiles and reported no injuries.

The plants will initially burn natural gas but will be required to switch to climate-friendly hydrogen by 2045.

RentGuarantor Holdings climbed 10% after raising its 2026 targets following strong trading in the first eight months of the year.

Adjusted earnings before interest, tax, depreciation and amortisation swung to £2.8 million from a £122,000 loss, while adjusted net profit swung to £2.9 million from a £392,000 loss.

RentGuarantor now targets full-year revenue of more than £14 million and net profit above £4 million, with revenue, adjusted Ebitda and adjusted net profit expected to be materially ahead of market expectations.
