Analysis of UK Listing Reforms: Hill Review and Structural Challenges to Competitiveness of London Stock Exchange

Abstract

The decline in initial public offerings (IPOs) on the London Stock Exchange (LSE) has raised concerns about the competitiveness of UK capital markets, particularly in the aftermath of Brexit and the rising popularity of alternative exchanges in the United States and Asia. Hill Review (2021) sought to address these challenges by recommending reforms to improve flexibility, streamline fundraising, and attract high-growth innovative firms to London. This study critically evaluates the effectiveness of these reforms and considers the wider structural factors namely valuation, liquidity and investor composition that continue to influence the ability of LSE to attract listings. The research adopts a qualitative methodology, drawing on statutory instruments, regulatory materials, case law, policy reviews, and secondary market evidence. Findings show that although reforms such as liberalising dual-class share structures and reforming prospectus liability reduced issuer burdens, they have not meaningfully improved IPO volumes or liquidity. Moreover, investor protection and governance standards have been weakened by diluted shareholder approval rights and higher liability thresholds. Comparisons with the US reveal deeper structural advantages in enforcement, disclosure, and liquidity provision, explaining the stronger pull of US exchanges. Persistent valuation discounts, weak domestic institutional participation and limited analyst coverage further undermine London’s competitiveness, suggesting regulatory reform by itself is insufficient in improving the attractiveness and competitiveness of UK capital markets.
