The CSSF consults on Guidance on Money Market Fund Liquid Asset Levels

On 15 May 2026 the CSSF informed about a report (the “2026 MMF report”) published by the European Commission (the “EC”) to the European Parliament and the Council on the adequacy of the Money Market Funds Regulation (MMFR) from a prudential and economic point of view and related frequently asked questions (FAQs) on the interpretation and implementation of certain legal provisions of the MMFR.

In its communication, the EC informed that the EU’s regulatory framework for money market funds (MMFs) continues to function well overall and mentioned that the market would benefit from additional guidance to support more consistent and well-calibrated supervision of MMFs across the EU, strengthening the resilience of the sector.

In this context, the EC identified a “market resilience” level of Weekly Liquid Assets (WLA). From a market-wide perspective, the 2026 MMF report indicates that these WLA levels would enable EU authorised MMFs to withstand future market stress events based on historical data and to mitigate against the potential transmission of shocks to the rest of the financial system and the real economy.

Following the 2026 MMF report and in close coordination with the EC, the French AMF, the Central Bank of Ireland and the CSSF are consulting on national guidance for enhanced MMF liquidity risk management practices based on the Commission-suggested market resilience levels, supported by increased supervisory scrutiny and engagement where MMFs fall below the market resilience levels of liquidity.

The objective of this communication is to inform market participants about the consultation paper “Guidance on Money Market Fund Weekly Liquid Asset Levels”, whose purpose is to set out details of the proposed guidance and to seek feedback from stakeholders on the proposals. The consultation paper contains more particularly the following:

• the guidance on Money Market Fund WLA levels; and
• the questions addressed to the industry on the proposed guidance.

The CSSF invites all stakeholders to provide responses to the consultation questions on the proposed guidance. These responses should be submitted electronically by email to opc_prud_risk@cssf.lu no later than 3 August 2026.
