UK Confirms Overhaul of Money Market Fund Rules to Boost Liquidity

Government moves to tighten liquidity guidance for funds after regulators' post-2020 review; implementation aimed by year-end pending parliamentary approval

By Derek Hwang

The British government has affirmed plans to change the regulatory framework for money market funds, mandating higher liquidity holdings and measures to ease asset sales during episodes of market stress. The reforms follow regulatory work since the March 2020 market dislocation and a 2023 consultation, and the new regime is expected to be in place by the end of the year subject to lawmakers' approval. The Financial Conduct Authority will publish further details shortly.

UK Confirms Overhaul of Money Market Fund Rules to Boost Liquidity

Key Points

  • Government confirmed reforms to money market fund rules, including higher liquidity requirements.
  • Reforms follow a 2023 consultation and a Bank of England recommendation aimed at improving resilience in sterling money market funds, which are widely used by companies for day-to-day funding and overnight cash parking - sectors affected include corporate treasuries and short-term funding markets.
  • The new regime is expected to be in place by the end of the year, but final implementation depends on parliamentary approval and forthcoming FCA guidance.

On Thursday, the British government confirmed it will reform the rules that govern money market funds, a segment of the financial system that came under intense regulatory scrutiny after the market upheaval of March 2020. That episode - when funds faced heavy redemptions and acute liquidity strains amid a COVID-19-related "dash for cash" - prompted authorities to consider measures to strengthen resilience.

The forthcoming changes will include new guidance requiring money market funds to hold larger buffers of liquidity, according to the government. The stated aim is to improve the ability of funds to withstand sudden outflows and to make it easier for them to sell assets in periods of stress.

Regulators have already taken steps in this direction. In 2023, Britain’s financial regulator ran a consultation on reforms designed to facilitate the orderly sale of assets by funds during stressed market conditions, following a recommendation from the Bank of England that the sterling money market funds sector - widely used by companies for day-to-day funding and for parking cash overnight - should be more resilient.

The government said the Financial Conduct Authority will issue a statement shortly with additional detail on the proposed measures. While the broad contours of the plan have been announced, the specific mechanics and operational guidance remain to be published by the FCA.

Officials said the new regulatory regime is expected to be implemented by the end of the year, but that timing is conditional on approval by lawmakers. That means the final shape and the schedule of the reforms will depend on the parliamentary process.


Policy makers are framing these steps as a response to lessons learned from the stress experienced by money market funds in 2020. The government's announcement reiterates a regulatory focus on ensuring funds used by businesses for short-term liquidity needs are better equipped to manage sudden runs and liquidity pressure.

Further information and technical detail are anticipated in the FCA's forthcoming statement, which will clarify how the higher liquidity requirements and asset-sale facilitation will be implemented operationally and enforced.

Risks

  • Implementation timing and final content are uncertain because the regime is subject to approval by lawmakers.
  • Operational and compliance details remain unclear until the Financial Conduct Authority issues its statement, leaving market participants without full guidance in the near term.
  • The reforms are a response to the 2020 episode when money market funds faced heavy redemptions and liquidity strains, highlighting the ongoing risk that funds can experience sudden stress under adverse market conditions.
