Executive summary

What you need to know

On April 15th, 2025, the European Securities and Markets Authority (ESMA) finalized its final report on the guidelines on the selection and calibration of Liquidity Management Tools (LMTs) applicable to UCITS and open-ended AIFs. The guidelines are mandated under the revised UCITS Directive and AIFMD, requiring fund managers to select and calibrate a minimum of two LMTs – One quantitative LMT and one ADT (Anti-Dilution Tool) – to manage redemptions under both normal and stressed market conditions.
The key words in the final report are calibration and monitoring. All LMTs need to have a solid quantitative foundation. Fund managers should review existing liquidity frameworks and disclosures now to ensure full compliance ahead of the RTS effective date.

Who is in scope and what is the timeline?

These guidelines apply to both UCITS, and open-ended AIFs managed within the EU. They come into effect alongside the Regulatory Technical Standards (RTS) on LMT characteristics. For existing funds, the guidelines must be applied within 12 months from the RTS application date. National Competent Authorities (NCAs) are required to notify ESMA of their compliance within two months of official publication.

What are Liquidity Management Tools?

Liquidity Management Tools (LMTs) are used by funds to manage redemption pressure and liquidity risk. These are typically implemented to ensure a fair treatment of investors whilst preserving the fund’s stability and reducing the risk of forced asset sales.
Under the ESMA guidelines, Liquidity Management Tools are grouped into two main categories: (1) Quantitative-based LMTs, and (2) Anti-Dilution Tools (ADTs). Quantitative LMTs manage the liquidity risk of a portfolio through the volume and timing with which investors can exit the fund, whereas ADTs are mainly used to adjust pricing or cost allocation to ensure that redeeming (or subscribing) investors bear the true cost of their transactions. This true cost incorporates both implicit and explicit costs of the fund flows.
Even though the guidelines provide some recommendations on which LMTs/ADTs to use, the Q&A clearly stresses that the selection of LMTs is to the discretion of the fund manager and the technical standards shall not restrict the ability of managers to use any appropriate liquidity management tool. However, LMTs that are not part of the official list do not count towards the requirement to have at least one quantitative-based LMT and one ADT.

Anti-Dilution Tools

Besides the quantitative LMTs, fund managers should also consider the selection of at least one ADT for all types of funds to mitigate material investor dilution and potential first mover advantage. The activation levels of ADTs should be set in advance and properly monitored under normal and stressed market conditions. In cases of limited market liquidity and/or valuation uncertainty, it can be challenging to activate ADTs. In these cases, fund managers may consider the use of other quantitative-based LMTs.
ADTs need to be applied in both normal and stressed market conditions to impose the estimated costs of liquidity on subscribing and/or redeeming investors. The estimated cost of liquidity should include both explicit and implicit transaction costs using, for example, the slippage methodology. It should also be based, as a starting point, on costs associated with transacting a pro-rata slice of all assets in the portfolio, unless this does not fairly reflect actual liquidity costs. The calibration of LMTs should be regularly reviewed and adjusted if needed.

What about disclosures to investors?

One of the most notable changes in the final guidelines relates to disclosures to investors. In earlier drafts, the ESMA had proposed detailed requirements for disclosing LMTs including activation thresholds, LMT policies and even elements of internal governance. This was met with a lot of resistance by the respondents to the ESMA’s earlier consultation paper. This criticism has resulted in the removal of these disclosure-specific guidelines in the final text.

However, the removal from the guidelines does not remove the obligation to disclose as existing Level 1 legislation (i.e., the UCITS directive and AIFMD) already mandates disclosures. Under the amended AIFMD (2024), an AIFM must make available to investors a detailed description of the AIF’s liquidity risk management, including redemption rights in normal and exceptional circumstances and the use of liquidity management tools. The AIFMs managing open-ended funds are also required to periodically disclose any material changes in liquidity arrangements through annual reports or investor updates.

The UCITS regulation likewise mandates a disclosure of the fund’s redemption policy and liquidity tools. The fund’s prospectus or constitutional documents must set out the redemption rights of investors under normal and exceptional circumstances, and any ability to activate LMTs.

Conclusion

The ESMA guidelines on LMTs is a step forward towards a unified framework for liquidity risk management in UCITS and open-ended AIFs. Fund managers are now required to select appropriate tools and to align governance, documentation, and disclosure practices with their selected LMTs and ADTs. The guidelines require specific attention for the implementation of monitoring tools and model validations under both normal and stressed market conditions.
