FTSE 100 Climbs to Two-Week High Amid Bank Rally and US Midterms

Britain's FTSE 100 closed at a two-week high on Wednesday, propelled by a strong rally in banking shares ahead of an anticipated interest rate hike by the Bank of England. The blue-chip index rose 1.79% to close at 10,829.21 points, marking its largest one-day percentage gain since early May. Meanwhile, the midcap FTSE 250 climbed 0.98% to reach a two-month high.

The financial sector provided the most substantial lift to the market, with banking stocks posting a 4.48% increase—their biggest one-day gain in nearly six months. Major institutions including HSBC, Standard Chartered, NatWest Group, Lloyds Banking Group, and Barclays saw gains ranging between 3.6% and 5.4%. Markets broadly anticipated a quarter-point rate hike from the central bank.

"Banks have massively underperformed this year... if you do have a rate hike, it obviously increases that net interest income, which can be a bonus; it would be supportive," noted Fiona Cincotta, senior markets analyst at City Index. Additionally, Metro Bank jumped 17.43% to top the FTSE 250 after reaffirming its financial forecasts.

Precious metal miners also surged, rising 6.51% for their largest one-day gain in nearly three months. This rally tracked a roughly 3% increase in gold prices, which were buoyed by a weakening US dollar. The dollar declined as international markets assessed the implications of the Democratic Party taking control of both the Senate and the House of Representatives in the US midterm elections.

The shift in US political control introduced concerns regarding potential stricter regulations on artificial intelligence and slower economic growth, contributing to the greenback's retreat. Stephen Innes, head of market strategy at SPI Asset Management, remarked that the artificial intelligence trade, having spent months worrying about financing costs, might now need to worry about politicians controlling the power grid.

In corporate news, medical device maker Smith & Nephew reduced its annual sales and profit guidance due to weaker-than-expected US demand for knee and hip replacements. Third-quarter sales for the company rose 3.4% to $1.55 billion, but management lowered full-year 2026 adjusted revenue growth expectations to around 3% and profit growth to 4%, causing shares to drop 2% in early trading.

Conversely, Marks & Spencer reported stronger-than-first-half results driven by robust food sales, helping push the Personal Care, Drug, and Grocery sector higher by 2.66%. On the energy front, oil prices tumbled significantly, with Brent crude futures dropping 4.3% to fall below the psychological threshold of $100 a barrel as traders evaluated ongoing geopolitical developments and peace negotiations.

Engineering firm Weir was among the notable laggards on the FTSE 100, dropping after highlighting short-term headwinds stemming from Middle East conflicts and Chilean mine disruptions, despite maintaining its overall annual outlook.
