New Operational Declaration Obligations from 16 April 2026
As of 16 April 2026, the Luxembourg supervisory framework formally integrates the AIFMD II Liquidity Management Tools (LMT) requirements, marking a decisive shift from highlevel governance expectations toward evidencebased operational compliance.
In line with AIFMD II and UCITS VI alignment, investment fund managers are now required to formally declare, document and evidence their Liquidity Management Tools setup through a structured submission process. This milestone reinforces the regulator’s focus on exante preparedness, operational transparency and supervisory comparability across fund structures.
This operational declaration framework aligns with the CSSF Communication to the Investment Fund Industry of April 2026 introducing the LMT eDesk selection and activation modules.
What changes in practice?
The new regime introduces a mandatory declaration process whereby the declarant must upload comprehensive documentation describing the policies and procedures governing Liquidity Management Tools, notably:
- The conditions for activation of each applicable LMT
- The decisionmaking framework and escalation process
- The governance layers involved (portfolio management, risk management, conducting officers)
- The deactivation criteria and communication channels
- The operational impact on investors and distribution arrangements
Importantly, this is not a theoretical exercise. Regulators expect detailed, fundspecific documentation demonstrating that LMTs do not only exist on paper, but are operationally workable under stressed conditions. Here is : Liquidity Management Tools Guidelines
From regulatory intent to operational execution
As previously highlighted in our AIFMD II & UCITS VI regulatory highlights, the revised framework reshapes liquidity risk management around three core priorities:
- Standardisation
Regulators aim to harmonise the availability and understanding of LMTs across EU jurisdictions, reducing interpretational gaps and market fragmentation.
- Accountability
The burden now sits clearly with managers to evidence decision readiness, not merely policy existence. Who decides, when, and based on which indicators must be explicit.
- Operational resilience
LMTs must be embedded into daytoday operating models, including data sourcing, reporting workflows, recordkeeping and auditability.
“These requirements apply to openended AIFs and UCITS in scope of the amended 2010 and 2013 Laws. “
Key implications for fund managers
For AIFMs and UCITS ManCos, this new obligation raises several practical considerations:
- Are LMT policies consistent across documents (prospectus, internal procedures, risk policies)?
- Is activation authority clearly assigned and documented ex ante?
- Can the firm demonstrate timely execution and traceability in a stressed liquidity scenario?
- Are declarations maintained, updated and defensible over time?
The quality and completeness of submitted documentation will be central to supervisory assessments going forward.

Looking ahead
The entry into force on 16 April 2026 should be seen not merely as a compliance deadline, but as a structural shift in liquidity risk governance. Firms that treat the declaration process as a oneoff administrative task risk future remediation, while those embedding it into a controlled, scalable operating model will be best positioned for supervisory scrutiny.
At FundSight, we continue to monitor this evolution closely and support market participants in translating regulatory expectations into efficient, auditable and sustainable operational processes.
