The FCA’s Short Selling Overhaul: Progress or Pitfall?

The Financial Conduct Authority (FCA) has just unveiled a landmark overhaul of short-selling rules in the UK, and it's raising as many eyebrows as it is cheers. Under new proposals, the identity of investors betting against UK-listed stocks will no longer be publicly disclosed. Instead, the FCA will publish only anonymised and aggregated short positions.

 

For years, the UK’s disclosure regime was among the most transparent in Europe, requiring investors to disclose short positions of 0.5% or more of a company’s share capital. With Brexit offering regulatory flexibility, the FCA is now pivoting towards a system more aligned with the U.S., where such disclosures remain confidential.

 

But while the move has been welcomed by hedge funds and some capital market participants, critics warn it could erode trust, weaken market discipline, and open the door to manipulation.

 

The rationale: Transparency, but make it efficient

 

At face value, the FCA's motivation is clear: reduce regulatory friction, support competitiveness, and streamline capital market rules. Hedge funds and institutional investors argue that disclosing short positions can expose them to front-running, squeeze tactics, or unnecessary scrutiny - particularly when their trades are part of complex, long/short strategies.

 

By anonymising disclosures, the FCA hopes to preserve market transparency without penalising liquidity providers or discouraging participation. The new disclosure deadline has also been extended to midnight (from 3:30pm), giving market participants more flexibility. Meanwhile, market makers will benefit from a simplified process to apply for exemptions.

 

In theory, this should enhance operational efficiency without undermining oversight. Investors must still report short positions over 0.2% privately to the regulator, and the FCA retains its enforcement powers. But the public will no longer know who is shorting what.

 

But are we inviting unintended consequences?

 

That’s the concern from critics, who argue the reforms may dilute accountability and transparency at a time when public trust in financial markets is already fragile.

 

Simon Youel of campaign group Positive Money called the changes “bewildering,” warning that they risk enabling hedge funds to engage in cynical trades that add no economic value and potentially destabilise markets.

 

Short selling itself is not inherently nefarious. When well-regulated, it serves several purposes:

 

· Identifying overvalued stocks

· Providing liquidity

· Aiding price discovery

 

But history shows how quickly sentiment can turn. From GameStop in 2021 to the collapse of Wirecard, transparency has been crucial in helping regulators, investors, and the public spot emerging distortions.

 

By removing individual disclosures, the UK may be opting for a “trust us, we’re watching” model. Although, in a high-speed, AI-assisted trading world, trust alone may not suffice.

 

Global context: Regulatory arbitrage or strategic repositioning?

 

The FCA’s shift is part of a broader post-Brexit rethinking of UK financial regulation. With the EU still requiring full public disclosure of significant short positions, the UK is sending a signal: London is open for business and willing to bend to attract capital.

 

Supporters of the changes - including the Managed Funds Association - argue that less burdensome disclosure rules will boost London’s appeal as a global financial centre. For fund managers, it's a win, but critics question whether this is a case of regulatory arbitrage that prioritises financial activity over economic substance.

 

Dennis Kelleher, head of U.S.-based advocacy group Better Markets, summed up the concern: “More financial activity often leads to bubble growth, not economic growth.”

 

Investor perspective: More questions than answers?

 

For investors, the issue isn’t just transparency; it’s the integrity of market signals. When a known short seller takes a position, it often prompts deeper scrutiny of the company’s fundamentals. That signal can catalyse governance improvements or expose fraud. Anonymised disclosures may dilute that mechanism.

 

Moreover, the risk of manipulation or “short-and-distort” strategies - where anonymous actors drive down a stock with coordinated bets and negative coverage - may rise in the absence of identifiable attribution.

 

At the same time, critics must reckon with the reality: public naming of short sellers has not always produced better outcomes. It has, at times, sparked populist backlash or led to unhelpful market volatility. The challenge is finding the right balance between healthy scrutiny and excessive exposure.

 

Conclusion: Transparency is evolving but should it?

 

The FCA’s reforms aim to reduce friction, boost competitiveness, and modernise oversight. In many ways, they do just that. But by moving short selling into a more opaque space, the UK may be exchanging short-term market efficiency for long-term risk.

 

The question isn't whether short selling should exist, because it certainly should. The real question is: how much transparency is necessary to preserve its usefulness without enabling its abuse?

 

With the consultation open until December 16, investors and market participants still have time to weigh in. This isn’t just about disclosure. It’s about what kind of market culture the UK wants to foster post-Brexit: one that prizes agility, or one that upholds accountability.
