Britain’s stock market posted a sharp gain on Thursday, lifting the FTSE 100 and pushing the London market’s capitalization to a record above 4.4 trillion pounds as investors bought back into equities after a volatile spell driven by geopolitical and inflation worries.
FTSE 100 Rises as London Market Value Tops 4.4 Trillion
The move matters because it signals that money is still willing to chase UK assets even after a recent risk-off stretch that had hit global stocks, gilts and commodities. A higher market value for the London bourse also boosts the paper wealth of pension funds, insurers and global investors with UK exposure, while improving liquidity and sentiment around domestically listed names.
The FTSE 100 rose 0.7% to 10,831.52, after trading as high as 10,866.82, while the broader iShares MSCI United Kingdom ETF, EWU, added 0.9% to $48.67. The index is now trading above both its 50-day and 200-day moving averages, and the RSI reading of 56.0 suggests momentum has recovered without yet looking stretched.
The advance came even as markets continued to weigh the fallout from renewed US-Iran tensions and their knock-on effect on energy prices. Brent and other global crude benchmarks have been firmer on supply-risk concerns, a dynamic that can support oil-linked UK blue chips while complicating the inflation outlook that has already kept investors uneasy.
For investors, the key question is whether Thursday’s buying marks the start of a broader rotation back into UK equities or just a relief rally in a market that has been buffeted by macro crosscurrents. A stronger pound can pressure exporters, but steady demand for large-cap London names suggests overseas capital has not abandoned the market despite recent turbulence.
The next test is whether the rally can hold if bond yields stay elevated and geopolitical risk remains high. Traders will be watching for follow-through in financials, energy and defensive stocks, along with any fresh moves in rates and oil that could either extend the gains or quickly reverse them.
