London Stocks: FTSE 100 and FTSE 250 Daily — 2026-09-12
The FTSE 100 faced significant pressure this week, closing at a six-week low of 10,670.06 on September 9th as Brent crude surged past $100 per barrel, fueling inflation fears and driving gilt yields toward 19-year highs. While Friday saw a tentative rebound driven by better-than-expected UK GDP data, the broader trend remains dominated by geopolitical energy risks and the accelerating exodus of major listings from London to New York.

FTSE 100 Hits Six-Week Low as Oil Tops $100
On September 9, 2026, the FTSE 100 closed down 141.6 points at 10,670.06, marking its lowest level in six weeks as Brent crude breached the psychological $100 barrier. This surge in energy prices, driven by Middle East tensions, directly impacted the index's sensitivity to inflation, causing a broad sell-off in non-energy sectors despite outperformance from oil majors like BP and Shell. The drop highlighted the market's vulnerability to external shocks, with the index extending losses into the following session before stabilizing.
Gilt Yields Climb Toward 19-Year Highs
The UK 10-year gilt yield rose toward 5.3% on September 10, approaching levels not seen in nearly two decades as investors priced in further Bank of England rate hikes. This spike in borrowing costs has increased the cost of capital for FTSE 250 companies, particularly affecting property and utility sectors, while also strengthening the pound against the dollar to approximately 1.35. The rising yields reflect a reassessment of the inflation outlook, creating headwinds for domestic-focused stocks that rely on cheaper financing.
London Listings Hit Decade Low Amid US Exodus
The London Stock Exchange recorded a decade low in new listings as companies increasingly flee for US markets, with recent high-profile exits including Flutter Entertainment’s completed shift to New York on August 3, 2026. This structural drain of liquidity is compounded by acquisitions such as Nuveen’s £9.9 billion takeover of Schroders, further eroding the depth of the UK equity market. Despite a doubling of total UK M&A value to £124.2 billion in the first half of 2026, the number of deals fell, signaling consolidation rather than growth in the domestic listing pipeline.
Miners and Recruiters Drag Index Early in Week
Earlier in the week, on September 7, the FTSE 100 slipped 13 points to 10,818 as miners like Fresnillo and recruiters Hays and PageGroup weighed on the index despite tentative signs of hiring recovery. The FTSE 250 declined 0.2% during this period, reflecting broader caution among mid-cap investors regarding global growth prospects. This early-week weakness set the stage for the more severe decline later in the week as oil prices accelerated.
Local view
German financial media noted the resilience of energy stocks, with ad-hoc-news.de highlighting that oil values defied general market hesitation, supporting the FTSE 100's relative strength compared to other European indices. Conversely, invezz.com/de warned that the Friday recovery rally, which ended a five-day losing streak, appeared "fragile" due to persistent geopolitical risks and uncertain monetary policy paths. Swiss outlet finanzen.ch reported the FTSE 100 closed firmer on Friday, September 11, but emphasized the volatility throughout the week.
