South Korea’s equity market has overtaken the UK in total size, marking a symbolic shift in global financial power as London continues to struggle with weak listings, low valuations and a shrinking pipeline of new companies.
The milestone reflects the growing dominance of Asian equity markets, particularly technology and export-heavy sectors, alongside persistent underperformance in the UK’s publicly listed universe.
The UK benchmark, the FTSE 100, has lagged global peers for much of the past decade, weighed down by a heavy concentration in banks, energy and consumer staples, and a lack of fast-growing tech champions.
By contrast, South Korea’s market — anchored by semiconductor giants and globally integrated manufacturers — has benefited from strong global demand cycles and sustained investor appetite for technology exposure.
The shift also reflects broader structural challenges facing London’s capital markets, including a steady decline in IPO activity, a wave of company relocations to New York and private markets, and ongoing concerns about relative valuations.
Analysts say the comparison highlights not just cyclical divergence but a deeper trend: the reweighting of global capital towards Asia, where growth prospects and technology exposure are increasingly concentrated.
For the UK, the development is likely to intensify debate over how to revive its equity markets, attract listings and retain global capital in an increasingly competitive financial landscape.
While the FTSE remains one of the world’s most established indices, its relative weight in global equity markets has been eroding — a trend underscored by South Korea’s rise into a higher tier of market capitalisation.
The shift is another reminder that global financial leadership is becoming more fragmented, with Asia continuing to close the gap on traditional Western market centres.
Sam Hields, Partner at OpenOcean said: “The news shouldn’t be surprising given the global demands for AI hardware. What is striking is the pace: Taiwan made the same leap earlier this month. Two countries have now overtaken the UK stock market in under four weeks, driven almost entirely by their chip manufacturing capabilities.
“The UK doesn’t have the same chip manufacturing industry as Korea or Taiwan, but it does have deep AI expertise and many innovative start-ups that should be a driving force for the UK economy. However, founders are being discouraged by a restrictive tax environment that disincentivises returns and forces our best and brightest to list in the US. We’re seeing an exodus of the talent and innovation that would enable the UK stock market to compete globally.
“The UK government needs to take greater action, setting out a coherent long-term policy that reduces operational costs and enables start-ups to effectively scale in the UK stock market. A £500 million sovereign AI fund cannot compete with the scale TSMC and Samsung are operating at, and scrapping the payments regulator is only a small step in the right direction.”
