AIFMD II Liquidity Management Tools: The Delegated Regulation in Force from 16 April 2026

The Commission Delegated Regulation on liquidity management tools for AIFs and UCITS entered into force in early March 2026 and applies from 16 April 2026 — the same date as the AIFMD II transposition deadline. For AIFMs running open-ended AIFs, this is the most operationally intensive requirement in the whole AIFMD II package.

This guide covers the harmonised list of liquidity management tools, the minimum selection requirement, how each tool works, the distinction between activation tools and anti-dilution tools, what your fund documents must say, and what managers need to do before the deadline.

Why Liquidity Management Tools Are Now a Regulatory Requirement

AIFMD II (Directive (EU) 2024/927) fundamentally changes how open-ended AIFs must manage liquidity risk. Before AIFMD II, LMT selection was largely discretionary — managers could choose which tools, if any, to build into their fund documents. Post-AIFMD II, it is a binding minimum requirement.

The policy rationale is clear: the 2020 COVID-induced liquidity stress, the 2022 LDI crisis in the UK, and the persistent mismatch risk in open-ended real asset and credit funds led European regulators to conclude that voluntary adoption was insufficient. The Delegated Regulation now specifies not just that managers must have tools, but how each tool must be calibrated and when it can be activated.

The requirement sits in Article 16(2a) of the amended AIFMD. It applies to:

• All AIFMs authorised under AIFMD managing open-ended AIFs in the EU
• UCITS management companies managing open-ended UCITS funds (with slightly different rules)
• External managers (where the AIFM is separate from the fund)

Closed-ended AIFs — the majority of private equity, real estate, and infrastructure funds — are not covered. The LMT requirements are specific to open-ended structures where investors can redeem on demand or on a set schedule.

The Harmonised List of Liquidity Management Tools

AIFMD II Annex V establishes a harmonised list of nine LMTs. The Delegated Regulation sets out the characteristics and operational parameters for each. No member state may permit tools outside this list to count toward the minimum requirement.

Tool	Category	Typical Use Case
Suspension of subscriptions, repurchases and redemptions	Exceptional (always available)	Extreme market stress; imminent fund closure
Side pockets	Exceptional (always available)	Segregating illiquid assets from liquid portfolio
Redemption gates	Quantitative-based activation tool	Redemption demand exceeds set threshold
Extension of notice periods	Quantitative-based activation tool	Temporary extension when redemptions strain liquidity
Redemptions in kind	Quantitative-based activation tool	Transferring assets to redeeming investors in lieu of cash
Redemption fees	Anti-dilution tool	Normal conditions; charge to redeeming investors offsetting costs
Swing pricing	Anti-dilution tool	Adjusting NAV to allocate transaction costs to net movers
Dual pricing	Anti-dilution tool	Separate subscription and redemption prices reflecting bid-offer spread
Anti-dilution levies (ADLs)	Anti-dilution tool	Charge applied separately from NAV to offset transaction costs

The Two Categories Explained

The Delegated Regulation distinguishes between two functional categories:

Quantitative-based activation tools are designed to restrict or modify redemptions when a specific threshold is crossed. Their activation is conditional — a trigger event or threshold must be reached before the tool can be switched on. These tools (gates, notice period extensions, redemptions in kind) are activated in stressed conditions and must be deactivated when the stress subsides.

Anti-dilution tools (ADTs) are designed to protect existing investors from the costs imposed by subscribing or redeeming investors. They can (and typically should) operate under normal conditions — the goal is to ensure that transaction costs from large flows are borne by the investor causing those costs, not by the broader fund. Redemption fees, swing pricing, dual pricing, and anti-dilution levies all fall in this category.

The Minimum Selection Requirement

Open-ended AIFs must select at least two LMTs from the harmonised list and make them available for use. The choice must be documented in the fund's constitutive documents and investment policy.

The Delegated Regulation provides guidance on how the minimum should be satisfied:

• At least one quantitative-based activation tool (gate, notice period extension, or redemptions in kind)
• At least one anti-dilution tool (redemption fee, swing pricing, dual pricing, or ADL)
• OR any two tools from the list, provided the combination is appropriate for the fund's liquidity profile

This means a fund choosing only two ADTs — for example, swing pricing plus redemption fees — may technically satisfy the minimum but could face challenge from its NCA if it has no tool to deploy when faced with a run scenario. In practice, most managers are selecting an ADT for normal conditions plus a gate or notice period extension for stressed scenarios.

Suspension and side pockets do not count toward the two-tool minimum. They are treated as always-available tools that every fund must have access to as a last resort. However, because both carry significant investor rights implications (suspension blocks all redemptions; side pockets segregate assets), the Delegated Regulation restricts their use to exceptional circumstances.

How Each Key Tool Works Under the Delegated Regulation

Redemption Gates

A redemption gate limits the amount that can be redeemed in a single dealing period, expressed as a percentage of NAV or as an absolute amount. When redemption requests exceed the gate threshold, requests are either:

• Pro-rated across all investors who submitted redemption requests that dealing day
• Queued to the next dealing period, with pro-ration applied until the gate is no longer in effect

The Delegated Regulation sets the following parameters for AIFs (UCITS have slightly different rules):

• The gate may be set at investor level (a single investor's redemption is capped), fund level (total redemptions in a dealing period are capped), or a combination of both
• The assessment may be done on a rolling window basis (looking at recent net outflows over multiple dealing periods) or on a per dealing day basis
• AIFMs must document the gate threshold in fund documents and explain how it will be calculated
• The gate must be operated consistently — discretionary application to individual investors is prohibited

Activation trigger: The AIFM determines the activation threshold in advance and documents it. Once the threshold is met in a dealing period, the gate automatically activates or the AIFM makes an explicit activation decision following the predefined procedure.

Extension of Notice Periods

The notice period tool allows the AIFM to temporarily extend the period between a redemption request and actual execution. This provides additional time to manage liquidity — selling assets or managing cash positioning — before having to pay out redemption proceeds.

Under the Delegated Regulation:

• The extension must be time-limited and proportionate to the liquidity stress being managed
• The maximum extension that can be applied in a single instance is defined in the fund documents
• The AIFM must communicate the extension to affected investors promptly
• Repeated use of notice period extensions for the same stressed condition is a warning sign that the underlying liquidity mismatch needs structural attention

Anti-Dilution Levies (ADLs) and Swing Pricing

Anti-dilution tools are the LMTs most managers are already deploying in some form. The Delegated Regulation tightens the methodology requirements.

For swing pricing, the fund NAV is adjusted upward when there are net subscriptions (to reflect the cost of buying assets) and downward when there are net redemptions (to reflect the cost of selling). The adjustment is the "swing factor."

Under the Delegated Regulation, the swing factor must:

• Include explicit transaction costs (brokerage, taxes, settlement fees) based on actual estimates
• Include implicit transaction costs (bid-offer spread on the assets) estimated on a best-efforts basis using recent market data
• Be reviewed and updated regularly — stale swing factors that no longer reflect actual trading costs are a supervisory concern

For ADLs, the levy is charged separately from the NAV — it does not adjust the NAV itself but is collected from the subscribing or redeeming investor. The Delegated Regulation requires the levy rate to be calculated using the same methodology as swing factors.

Dual pricing (separate issue and redemption prices) is the third anti-dilution mechanism. Unlike swing pricing, which moves a single NAV, dual pricing sets different prices for buyers and sellers simultaneously. It requires robust governance to ensure the bid-offer spread is set consistently and justified.

Redemptions in Kind

Redemptions in kind (RiK) allow the fund to transfer assets directly to a redeeming investor rather than selling those assets to raise cash. This protects remaining investors from forced asset sales in illiquid conditions.

RiK is an activation tool — it is not deployed under normal conditions. The Delegated Regulation treats it as a quantitative-based LMT subject to specific constraints:

• Must be offered pro-rata based on the redemption amount relative to the fund's total assets (to ensure equal treatment of redeeming investors)
• The selection of assets to transfer must reflect the overall composition of the fund's portfolio — the manager cannot cherry-pick the most liquid assets to transfer to some investors while retaining illiquid assets for others
• Requires prior notification to the NCA in most jurisdictions
• Requires careful tax analysis — the receipt of assets rather than cash may trigger different tax treatment for the redeeming investor

Side Pockets

Side pockets segregate illiquid or hard-to-value assets from the main fund portfolio into a dedicated sub-fund or separate share class. Existing investors receive an equivalent interest in the side pocket; new investors cannot subscribe to it.

The Delegated Regulation restricts side pocket use to exceptional circumstances — specifically situations where an asset becomes illiquid, subject to regulatory proceedings, or where valuation has become unreliable. Side pockets are not a tool for managing normal redemption flows.

Key requirements:

• The side pocket structure must be established in advance in the fund documents — managers cannot create a side pocket at the moment of stress without prior authorisation from investors or the NCA
• Once established, the side pocket winds down as the illiquid assets are realised — it is not a permanent structure
• Management fees on side pocket assets are typically restricted or prohibited

Fund Document Requirements

By 16 April 2026, the constitutive documents and investor disclosure documents for open-ended AIFs must be updated to reflect LMT selection. Specifically:

Fund rules / articles of association / partnership agreement: Must specify which LMTs are selected, the conditions for activation, and the procedures for deactivation and investor notification.

Prospectus / offering document: Must describe each selected LMT in plain language, including:

• What the tool is and how it operates
• Under what circumstances it will be activated
• How investors will be notified when a tool is activated
• What recourse investors have (if any) after activation

Liquidity policy: The AIFM's own internal liquidity management policy (required separately under AIFMD Article 16(1)) must be updated to cross-reference the selected LMTs and set out the internal governance process for activating and deactivating each tool.

For Luxembourg funds, the CSSF has indicated it will publish supervisory guidance on how it expects Luxembourg AIFMs and UCITS management companies to implement LMTs. Managers should monitor CSSF circulars in Q1 2026.

For Dutch funds, the AFM has flagged LMT implementation as a supervisory priority for 2026, particularly for open-ended real estate and credit funds where liquidity mismatch risk is elevated.

NCA Notification: Activation and Deactivation

When an AIFM activates or deactivates an LMT, it must notify the relevant NCA — the home-state NCA for the AIFM, not the fund's domicile NCA (where those differ). The Delegated Regulation requires:

• Prompt notification of activation — in most jurisdictions this means same-day or next business day
• Notification of deactivation when the stressed conditions that triggered activation have resolved
• Content of notification: the tool activated, the trigger circumstances, the number and aggregate value of affected redemptions, and the expected duration of the activation

The notification requirement does not require NCA approval before activation. AIFMs can activate LMTs when the trigger conditions are met — the notification is ex-post and informational, not a prior consent mechanism. This is important: waiting for regulatory approval before applying a gate would defeat the purpose of having the tool.

Transition Period for Existing Funds

The Commission Delegated Regulation includes a one-year transitional period for funds constituted before 16 April 2026:

• These funds are deemed compliant with the LMT requirements until 16 April 2027
• They may opt into the new regime from 16 April 2026 subject to notifying their NCA
• The transition period is designed to give time for funds to update constitutive documents, obtain investor approval where required, and implement the operational changes

New funds constituted from 16 April 2026 onwards must comply from inception — the transition period does not apply.

The one-year window should not be taken as a reason to delay. Updating fund documents in most jurisdictions requires advance preparation, legal review, and in some cases unitholder or shareholder approval. Managers targeting a mid-2026 document update may find it difficult to complete the process before the April 2027 deadline if they start too late.

Frequently Asked Questions

Does the LMT requirement apply to a Luxembourg AIFM managing a Dutch AIF?

Yes. The LMT requirement attaches to the AIFM's home-state authorisation and the fund's open-ended structure. Where the AIFM is Luxembourg-authorised and the AIF is Dutch-domiciled, the AIFM (as the manager) is responsible for selecting and implementing LMTs consistent with AIFMD II. The CSSF (as the AIFM's home NCA) is the competent authority for supervisory purposes. The AFM (as the AIF's host NCA) may also have supervisory interest given the Dutch fund's domicile.

Does swing pricing require a live technology system change?

For most fund administrators, yes. Swing pricing requires the NAV calculation engine to apply an adjustment to the provisional NAV based on that dealing period's net flow and the pre-calibrated swing factor. Funds that outsource NAV calculation to a fund administrator need to confirm that the administrator's system supports swing pricing and that the swing factor is being updated on the required frequency. The RTS requires regular review of swing factors — stale calibrations are a compliance risk.

Can we use the transition period to defer selection past April 2026?

Yes — existing funds have until 16 April 2027 under the transition period. However, managers should start the selection and documentation process now. Retrospective document amendments that are rushed tend to be lower quality and may attract NCA scrutiny. The transition period is a compliance window, not a permission to ignore the requirement.

Are UCITS subject to the same minimum selection requirement?

UCITS are subject to the same harmonised list and the same two-tool minimum as open-ended AIFs. The only exception is money market funds, which may select just one LMT. However, UCITS gate thresholds must be expressed as a percentage of NAV only (unlike AIFs which allow multiple expression methods), and only fund-level gating is permitted for UCITS (not investor-level gating). UCITS are also subject to ESMA guidelines on LMTs published alongside the RTS. The rules for suspension and side pockets follow the same exceptional-use principle.
