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

What Changed

• - The CSSF, in coordination with the European Commission, AMF (France) and Central Bank of Ireland, is consulting on national guidance that operationalises the Commission’s “market resilience” levels of Weekly Liquid Assets for MMFs, in addition to e
• The guidance will introduce non-binding but supervisory‑relevant WLA benchmarks designed to indicate when an MMF’s liquidity profile may warrant closer scrutiny and additional supervisory engagement.
• The consultation builds on the European Commission’s 11 May 2026 report, which identifies WLA benchmarks of 20% for VNAV MMFs and 40% for LVNAV and CNAV MMFs, compared with the MMFR regulatory minima of 15% and 30% respectively.
• The guidance is intended to support more consistent and well‑calibrated supervision of MMFs across the EU, specifically on liquidity resilience under stress.
• MMFs that fall below the identified “market resilience” WLA levels, even while remaining compliant with the MMFR minimum percentages, can expect increased supervisory scrutiny, closer monitoring and potentially more frequent engagement by the CSSF.
• The consultation paper sets out the proposed WLA guidance and includes specific questions for industry feedback, requiring firms to consider how the benchmarks should interact with their liquidity risk management, stress testing and escalation framew

Suggested Considerations

• Review the CSSF consultation paper “Guidance on Money Market Fund Weekly Liquid Asset Levels” in detail and map the proposed WLA resilience benchmarks against existing MMF liquidity policies, procedures and internal limits.
• Perform a quantitative impact analysis comparing each MMF’s historical and current WLA levels against both MMFR minimum requirements and the Commission’s market resilience benchmarks (20% for VNAV; 40% for LVNAV and CNAV) to identify potential shortfalls or pressure points.
• Assess and, where necessary, update MMF liquidity risk management frameworks to incorporate explicit internal WLA targets, triggers and escalation procedures linked to the new resilience benchmarks, including governance oversight and board reporting.
• Integrate the proposed WLA resilience levels into stress testing programmes under Article 28 MMFR, ensuring scenarios reflect the ability of funds to maintain or restore WLA around the benchmark levels under severe but plausible market stress.
• Revisit know‑your‑investor / liability profile analysis under Article 27 MMFR to ensure that internal WLA targets adequately reflect investor concentration, redemption behaviour, dealing frequency and distribution channels.
• Prepare and coordinate a formal response to the consultation by 3 August 2026, addressing the specific questions in the paper from risk, portfolio management, compliance and legal perspectives and articulating any operational or market impacts.
