FCA Update on Reforms to the UK Money Market Fund Regulation

Why It Matters

Higher liquidity buffers aim to bolster financial‑system stability while preserving MMFs as a low‑cost cash‑management option for investors. Asset managers will need to adjust portfolio holdings and risk‑management processes to meet the new standards.

Key Takeaways

• FCA proposes 40% WLA for stable‑NAV MMFs, 20% for variable‑NAV
• Minimum daily liquid asset (DLA) levels remain unchanged
• Delinking of liquidity tools from NAV stability retained
• Updated rules align with Bank of England stress‑test findings
• Legislation to repeal current MMF regime expected by end‑2026

Pulse Analysis

Money‑market funds sit at the intersection of short‑term investing and cash management, offering investors an alternative to bank deposits. Their popularity surged after the 2008 crisis, but recent market turbulence exposed vulnerabilities in liquidity provisioning. Regulators worldwide have responded by tightening standards, and the UK’s Financial Conduct Authority (FCA) is now refining its approach to ensure MMFs can withstand sudden outflows without jeopardising broader financial stability.

The FCA’s revised framework retains the existing daily liquid asset (DLA) floor while setting clearer weekly liquid asset (WLA) targets: 40% for stable‑NAV funds and 20% for variable‑NAV funds. This calibrated shift reflects findings from the Bank of England’s system‑wide exploratory scenario, which indicated that modern market structures may limit the severity of MMF redemptions. By keeping the delinking of liquidity fees and redemption gates from NAV stability, the regulator preserves flexibility for fund managers to manage liquidity risk without eroding investor confidence. Enhanced Know‑Your‑Customer (KYC) rules will also focus on concentration risk, further tightening oversight.

For asset managers, the new expectations translate into a need to reassess portfolio composition, potentially increasing holdings of high‑quality liquid assets to meet the higher WLA thresholds. Investors stand to benefit from a more resilient MMF market, reducing the likelihood of forced sell‑offs during stress events. The proposed rules are slated for legislative approval by the end of 2026, giving firms a clear timeline to adapt. As the UK moves to replace its Money Market Funds Regulation, the updated standards signal a broader trend toward stronger liquidity governance across the financial sector.
