London’s Market Stages a Comeback

London’s financial sector, long overshadowed by continental and U.S. counterparts since the 2016 Brexit referendum, is enjoying an unexpected renaissance. The FTSE 100, the city’s flagship index, has surged nearly 10% so far in 2025, outpacing Europe’s STOXX 600, which has climbed 7.5%. Investors are cautiously optimistic as the narrative around UK equities shifts from pessimism to newfound opportunity.

The return of foreign capital marks a potential turning point for the city’s reputation as a global financial hub. Once written off after years of depressed valuations and stagnant returns, London is leveraging a confluence of tailwinds—regulatory reforms, competitive stock prices, and a robust pound sterling—to lure back institutional and retail investors.

Foreign Funds Flow as Perceptions Shift

Over the past six weeks, the FTSE 100 has consistently outperformed the STOXX 600 for the longest run since late 2022. According to LSEG data, the big-cap index is up nearly 18% in dollar terms so far in 2025, marking the largest dollar-denominated return since 2009. This stands in contrast to the S&P 500, up only 6% year-to-date, despite also reaching record highs.

This change in fortune comes as foreign institutions—endowments, pension funds, asset owners, and wealth managers—begin to reallocate to the UK, says Justin Onuekwusi, CIO at St. James’s Place. “We are seeing signs of big asset allocators coming back to the UK … many of whom were significantly underweight following Brexit,” says Onuekwusi.

The UK has reported a net outflow of $20 billion from equities in 2025, according to recent Barclays data. Yet, the pace of outflows has dramatically slowed over the last month—a signal of stabilizing sentiment. Europe, by contrast, has posted a modest $13 billion inflow, with slowing momentum seen across the continent’s indices.

Sterling’s Strength and Competitive Valuations

The British pound has rallied about 7% against the U.S. dollar in 2025, buoyed by reduced U.S. capital inflows amid heightened political uncertainty. This currency strength, while usually a headwind because 80% of FTSE 100 revenues come from overseas, hasn’t deterred the ongoing rally. Notably, the pound is close to a four-year high against the dollar but remains weaker against the euro, supporting UK exporters’ competitiveness within the EU.

London’s outperformance is further fueled by its relative value. The FTSE’s 12-month forward price-to-earnings (P/E) ratio stands at 12.5—its highest in five years—compared to 14.1 for the STOXX 600. The S&P 500, by contrast, trades at a hefty 23 times forward earnings, a near 10-point premium over London. The valuation gap, which hit historical extremes after Brexit, is now narrowing and inviting global investors who are hunting for undervalued opportunities.

“The relatively poor performance we’ve seen in the UK versus particularly the U.S. over the past two years has begun to unwind. We’re in the foothills of that,” comments Michael Stiasny, head of UK Equities at M&G Investments. “The UK market has traded at a significant discount.”

Defensive Strength and Reliable Blue Chips

The FTSE 100 is home to defensive industrial titans as well as global growth names. Healthcare giants like AstraZeneca, utilities, and food retailers such as Tesco buffer the index against economic downturns, while resource-driven companies like Anglo American and BP provide exposure to surges in energy and commodities markets.

According to AJ Bell analyst Dan Coatsworth, “The UK stock market is the calming cup of tea and biscuit in an uncertain world. There’s nothing fancy on offer, just reliable names that do their job day in, day out.”

Policy and Regulatory Tailwinds

The UK’s policy landscape is shifting as well. Following this week’s announcement by the nation’s financial regulator to implement new rules designed to boost Britain’s capital markets, Chancellor Rachel Reeves called on the financial services industry to present a more positive image to prospective investors. Pitching the FTSE 100 as a home for steady long-term returns, the government is eager to restore confidence in local markets and encourage retail participation.

One brighter spot: Britain’s relatively stable trading relationship with the United States. As the UK benefits from an in-place trade deal, the European Union faces looming tariff uncertainties—potentially as high as 30%—if talks with the U.S. fail to make headway before August 2025.

Lingering Risks: Economy and Outflows

Despite the equity market’s robust performance, the broader British economy faces challenges. Inflation remains stubbornly above the Bank of England’s 2% target, business activity is sluggish, and employment figures have softened, raising questions about the sustainability of the current rally.

Sebastian Raedler, head of European equity strategy at Bank of America Merrill Lynch, cautions that much of the FTSE’s gains reflect currency moves and are in line with the broader European recovery. “Net-net, the FTSE has mildly outperformed, but a 2% outperformance this year would rank further down the radar given global volatility,” Raedler observes.

Outlook: Is London’s Rally Sustainable?

Looking ahead, much will depend on whether London’s market can attract lasting inflows and continue narrowing its valuation gap. With competitive pricing, reforms in the IPO and listing framework, and improving narratives around UK plc, the city is better positioned than at any point in the past five years. However, global headwinds—ranging from geo-economic tensions, to inflationary pressures, and election uncertainty in major economies—still pose systemic risks.

For long-term investors, the signs of a revitalized London may be too compelling to ignore. As valuations stabilize and the regulatory environment becomes more accommodating, global capital may once again view the UK market as a critical pillar of international portfolios.
