Short sellers in the UK will soon see a significant change in how their positions are reported, with the Financial Conduct Authority (FCA) set to announce new rules that will allow them to operate under increased anonymity. Under the forthcoming regulations, the identities of those betting against a company’s share price will no longer be publicly disclosed. Instead, the FCA plans to publish only the total short positions of these investors on an anonymised and aggregated basis.
This shift comes as the UK moves away from EU regulations that mandated public disclosure of all short positions exceeding 0.5 percent of a company’s shares. The UK is embracing a disclosure framework similar to that of the United States, where short positions are reported only in aggregate form, preserving the anonymity of investors.
In addition to this change, the FCA is poised to relax the threshold at which short sellers must inform the regulator of their positions. The reporting requirement is expected to increase from positions above 0.1 percent of a company’s share capital to those above 0.2 percent. This adjustment aligns with the UK government’s calls for reducing regulatory burdens to spur economic growth and enhance competitiveness.
While hedge funds are anticipated to welcome these changes, concerns about market manipulation have been voiced. Critics argue that reducing transparency in short selling may create opportunities for hedge funds to exploit market weaknesses without accountability. Simon Youel, from the campaign group Positive Money, expressed skepticism, stating that although short selling can have functions in theory, it is often abused in practice, undermining market stability.
In contrast, proponents of the reform assert that it could enhance the UK’s attractiveness as a global financial hub. Rob Hailey from the Managed Funds Association, representing hedge funds, emphasized that “smart reforms” would encourage investment and drive economic growth in the UK.
This legislative shift was initiated earlier this year when the Treasury introduced changes to replace previous EU-derived laws. Alongside the moves towards anonymity in short selling, the UK has already lifted certain restrictions on “naked” short selling of sovereign bonds, allowing investors to short without first borrowing the underlying securities. However, the FCA is expected to maintain the ban on “naked” short selling of shares.
As these changes unfold, the financial landscape in the UK is poised for a transformation that could redefine short selling practices and regulatory approaches.
