Policy Paper: Reforms to Money Market Fund Regulations

Why It Matters

Stronger MMF rules protect investors and reduce systemic risk by preventing rapid fund outflows during stress. Aligning with global standards also preserves the UK’s status as a leading cash‑management hub.

Key Takeaways

• FCA to impose stricter liquidity buffers on UK money market funds
• New rules require daily stress testing and transparent reporting
• NAV valuation changes aim to reduce investor runs during market stress
• Smaller funds may face higher compliance costs under revised regime
• Reforms align UK MMFs with Basel III and EU Fund Directive

Pulse Analysis

Money‑market funds have become a cornerstone of short‑term financing for banks, insurers, pension schemes and corporate treasuries. Their ability to offer daily liquidity at near‑cash yields makes them an attractive alternative to traditional deposits, especially in a low‑interest‑rate environment. However, episodes of market turbulence—such as the 2023 UK banking strain and the 2024 Eurozone liquidity crunch—revealed that MMFs can amplify funding shocks when investors rush to redeem, prompting regulators to reassess the sector’s safety net.

The new UK framework introduces several technical upgrades. Funds will be required to hold higher high‑quality liquid assets, conduct daily stress‑scenario analyses, and publish real‑time transparency reports on portfolio composition and maturity buckets. NAV pricing will shift from a purely amortised‑cost model to a more market‑based approach, reducing the likelihood of sudden valuation gaps that can trigger runs. Smaller funds, which previously benefited from lighter oversight, will now face proportional compliance costs, encouraging consolidation or the adoption of shared service platforms.

For market participants, the reforms promise greater confidence and stability. Investors gain clearer insight into fund liquidity and risk exposure, while issuers can continue to rely on MMFs for efficient cash management. By harmonising UK rules with Basel III and the EU Money Market Fund Directive, the FCA also positions London as a regulator that meets international best practices, potentially attracting cross‑border capital. Nonetheless, the transition will require operational adjustments and may temporarily compress yields as funds rebalance toward higher‑quality assets.
