FCA Reviews Investment Fund Diversification Rules in Listing Overhaul

The UK's Financial Conduct Authority has initiated a review of how Listing Rules apply to certain investment entities. The focus is on diversification requirements, a sensitive aspect of London's market framework. In a statement dated 03/03/2026, the regulator said it will assess if current eligibility criteria, particularly on risk-spreading, are overly restrictive.

This review is part of the broader Primary Markets Effectiveness Review, which previously drove major reforms in 2024. The FCA plans to publish a consultation paper and complete the work before year-end. The move reopens the debate on balancing modern capital strategies with investor safeguards.

At the core is a long-standing rule that listed investment entities must demonstrate adequate risk diversification. This rule was designed to prevent single-asset vehicles from listing as diversified funds. Market participants argue the rule may not reflect modern capital deployment. They cite private credit funds, infrastructure vehicles, and venture capital trusts as examples of potentially concentrated yet disciplined strategies.

Industry stakeholders have warned the FCA that current interpretations may deter specialist vehicles from listing in London, especially when other jurisdictions have fewer structural hurdles. The review aligns with ongoing concerns about London's competitiveness as a listing venue. Since 2020, many growth companies have chosen US exchanges, while asset managers have favoured offshore domiciles like Guernsey and Jersey for listed vehicles targeting UK investors.

The 2024 reforms streamlined the listing structure and relaxed some shareholder approval rules. The current review suggests the regulator sees further room for adjustment, particularly for entities that do not fit traditional diversification models. Beyond IPOs, listed investment vehicles support significant secondary trading and advisory activity. Restrictive standards could drive this activity to other jurisdictions.

The FCA also indicated it will examine whether listing rules and company law ensure boards uphold shareholder rights and manage conflicts appropriately. This follows 2024 reforms that reduced mandatory shareholder votes in some cases. If diversification rules are relaxed, increased asset concentration could amplify governance considerations around board independence and disclosure.

The regulator's dual focus suggests any structural flexibility may be paired with closer scrutiny of governance, not a broad easing of oversight. Any loosening of diversification tests is likely to be balanced by stronger expectations on board oversight and conflict management.

The FCA's upcoming consultation paper will seek feedback on key issues. These include whether diversification thresholds should be more principles-based, if specialist strategies need tailored treatment, and if concentrated vehicles require extra disclosure. The outcome will shape London's capacity to accommodate specialist investment structures and influence where asset managers choose to list in future.
