Liquidity Risk Management Programmes for Open-End Funds
SEC Rule 22e-4, codified at 17 C.F.R. § 270.22e-4 under the Investment Company Act of 1940, requires every open-end management investment company — including Exchange-Traded Funds but excluding money market funds regulated under Rule 2a-7 and In-Kind ETFs — to adopt and implement a written liquidity risk management programme reasonably designed to assess and manage the fund's liquidity risk and to reduce the risk that the fund will be unable to meet its redemption obligations without materially diluting the interests of remaining shareholders.
The programme must incorporate five specified elements: assessment and periodic review of the fund's overall liquidity risk; classification of each portfolio investment into one of four liquidity categories based on the number of days in which it could reasonably be converted to cash or sold without significantly changing market value; establishment and periodic review of a highly liquid investment minimum where required; a limit prohibiting more than 15% of net assets from being held in illiquid investments; and procedures for managing liquidity in stressed conditions and for board reporting on liquidity risk management matters.
Rule 22e-4 is the most comprehensive liquidity governance standard in the registered investment company framework — the rule that requires every mutual fund and ETF to maintain a rigorous, documented understanding of how quickly and at what cost each of its portfolio holdings can be liquidated, and to manage the aggregate liquidity profile of the portfolio in a manner that ensures the fund can meet its redemption obligations to shareholders without forcing sales at distressed prices that harm remaining shareholders.
The August 2024 guidance — published alongside amendments to Forms N-PORT and N-CEN — addressed the most consequential areas of interpretive uncertainty that had emerged since the rule's implementation, confirming the frequency with which liquidity classifications must be reviewed, clarifying the definition of cash for programme purposes, and providing guidance on the factors funds must consider in establishing their highly liquid investment minimums.
Overview and Regulatory Purpose
Open-end funds — both conventional mutual funds and Exchange-Traded Funds — are unique among financial intermediaries in the combination of obligations they assume with respect to their investors.
They promise daily redemption rights to shareholders who may redeem at any time at the fund's next computed NAV, while simultaneously pursuing investment strategies that may involve portfolio holdings ranging from the most liquid exchange-listed equities to less liquid high-yield corporate bonds, bank loans, emerging market securities, structured products, and alternative instruments that may take days, weeks, or even months to sell at fair value in normal market conditions.
This combination — guaranteed daily liquidity to investors, portfolio investments with varying degrees of actual market liquidity — creates a structural tension that the Investment Company Act has addressed since 1940 through Section 22(e)'s general requirement that funds remain capable of honouring redemption requests, but that was not comprehensively regulated through a specific operational framework until Rule 22e-4's adoption in 2016.
The March 2020 COVID-19 liquidity event — during which many mutual funds experienced elevated redemption pressure simultaneously with sharp declines in the liquidity of their fixed income and alternative asset holdings, creating a compressive stress on the fund industry that required extraordinary Federal Reserve intervention in the commercial paper and Treasury bill markets to stabilise — demonstrated both the systemic significance of open-end fund liquidity management and the consequences of inadequate preparation for stress scenarios.
Rule 22e-4 had been operative for fewer than two years when the March 2020 event occurred, and the Commission's post-event analysis — which informed the November 2022 proposal and the August 2024 guidance — identified specific areas of Rule 22e-4 implementation that had proven inadequate when confronted with actual market stress.
The rule's fundamental investor protection objective is to ensure that the liquidity profile of a fund's portfolio is sufficiently understood, monitored, and managed that the fund can meet redemption demands at fair value — without being forced to liquidate holdings at distressed prices that harm remaining shareholders — even under market conditions materially worse than those prevailing when the portfolio was constructed.
A fund that meets this objective protects both the redeeming shareholders, who receive fair value for their interests, and the remaining shareholders, whose NAV is not diluted by distressed portfolio sales necessitated by inadequate liquidity management.
Statutory Authority and Rulemaking History
Rule 22e-4 derives its statutory authority from Section 22(e) of the Investment Company Act of 1940, which provides that no registered investment company shall suspend the right of redemption, or postpone the date of payment or satisfaction upon redemption of any redeemable security for more than seven days after the tender of such security, subject to limited enumerated exceptions.
Section 22(e)'s seven-day redemption obligation is the statutory baseline that Rule 22e-4's liquidity risk management framework is specifically designed to ensure funds can honour — a fund that cannot liquidate sufficient portfolio assets within seven days to meet redemption requests without significantly changing market values is at risk of violating Section 22(e)'s mandatory redemption obligation.
The Commission adopted Rule 22e-4 on October 13, 2016 — Investment Company Act Release No. IC-32315, published at 81 FR 82142, November 18, 2016 — as part of a comprehensive liquidity reform package that also adopted Rule 30b1-10 and Form N-LIQUID and made amendments to Forms N-PORT and N-CEN.
The rule's compliance date was modified in February 2018 — Investment Company Act Release No. IC-33142 — when the Commission granted a six-month extension for the portfolio classification, HLIM, and board approval provisions, with larger entities required to comply by June 1, 2019 and smaller entities by December 1, 2019.
The August 28, 2024 Commission release — Investment Company Act Release No. IC-35308 — constituted the most significant post-adoption regulatory action affecting Rule 22e-4, simultaneously adopting amendments to Forms N-PORT and N-CEN and issuing substantial interpretive guidance on three areas of programme implementation where monitoring had revealed industry-wide compliance concerns.
The August 2024 release withdrew the proposed liquidity risk management programme amendments that had been included in the November 2022 proposal — including the mandatory stressed liquidity classification methodology, the proposed HLIM changes, and the proposed swing pricing mandate addressed in Rule 22c-1's history — without adopting them in final form, leaving the rule's operative framework in its pre-2022 form with the additional interpretive guidance.
Key Provisions and Operative Requirements
Rule 22e-4(b)(1) establishes the five elements that every fund's liquidity risk management programme must incorporate as a minimum, though programmes may extend beyond these elements based on the fund's specific liquidity risk profile and investment strategy.
The first required element is assessment and periodic review of the fund's overall liquidity risk. The fund must assess and periodically review the risk that it will be unable to meet redemption obligations without diluting remaining shareholders' interests — a holistic, portfolio-level liquidity risk assessment that considers the fund's investment strategy, redemption history and anticipated redemption patterns, the composition and liquidity profile of the portfolio, the fund's use of borrowings and derivatives that may affect liquidity, and short-term and long-term cash flow projections.
The assessment must address liquidity risk under both normal and stressed market conditions, since conditions under which portfolio assets can be readily sold at fair value under normal markets may be drastically different from conditions during market stress events.
The second required element is classification of portfolio investments into four defined liquidity categories. The fund must classify the liquidity of each portfolio investment — and each position within a portfolio investment type — into one of four categories based on the number of days in which the fund reasonably expects the investment to be convertible to cash or capable of being sold in current market conditions without the conversion or sale significantly changing the market value of the investment.
Highly liquid investments — the first and most liquid category — encompasses cash held by the fund and any investment the fund reasonably expects to be convertible into cash in current market conditions within three business days or less without the conversion significantly changing the market value.
Under Rule 22e-4's definitions, cash means U.S. dollars held by or for the fund, including receivables — it does not include foreign currencies, a point clarified by the August 2024 guidance and one with significant portfolio construction implications for globally diversified funds that hold substantial balances in non-dollar currencies between settlement dates.
The distinction between dollar-denominated cash and foreign currency holdings has direct implications for fund compliance with HLIM requirements, since foreign currency balances that funds may have informally classified as cash equivalents cannot count toward a fund's highly liquid asset holdings under the rule's strict definition.
Moderately liquid investments — the second category — encompasses investments the fund reasonably expects would be convertible to cash within three to seven calendar days without significantly changing market value.
The three-to-seven-day window captures investments that can be liquidated within a week's time but that require slightly more trading time than the most liquid instruments — characteristics common to many investment-grade corporate bonds, some government securities in less active markets, and certain equity securities with meaningful average daily trading volume but not sufficient to absorb large block sales within one to three days.
Less liquid investments — the third category — encompasses investments the fund reasonably expects could be sold within seven calendar days, but where the sale could not be settled within that period.
This category captures instruments that can be sold but whose settlement mechanics extend beyond the seven-day redemption window that Section 22(e) establishes — certain international securities, instruments settling through specialised clearing mechanisms, and similar investments where the sale transaction can be completed but the resulting cash may not be available to fund a redemption within the required timeframe.
Illiquid investments — the fourth and most restrictive category — encompasses investments the fund reasonably believes cannot be sold in the open market in current market conditions in seven calendar days or less without significantly changing the market value of the investment. The 15% illiquid investment limit applies to this category: no fund subject to Rule 22e-4 may hold illiquid investments representing more than 15% of its net assets.
This hard limit is the rule's most operationally definitive requirement — unlike the HLIM, which is fund-specific and based on assessment of the fund's particular redemption risk profile, the 15% illiquid limit applies universally as an absolute ceiling on illiquid investment exposure for all subject funds regardless of their investment strategy, investor base, or redemption history.
The classification framework requires that funds classify investments based on both the amount of time the investment would take to convert to cash and the market impact of the sale — a sale that would significantly change the market value of the investment is not a permissible basis for classification in a more liquid category even if the sale transaction itself could be completed within the relevant time period.
This market impact consideration is particularly significant for funds that hold large positions in individual securities or that invest in markets with limited depth, where even a moderately sized sale would be expected to move the market price against the fund.
The August 2024 guidance addressed a significant industry compliance concern about the frequency with which funds must review and update their liquidity classifications.
The guidance confirmed that Rule 22e-4 requires funds to maintain policies and procedures reasonably designed to facilitate intra-month review and updating of liquidity classifications when changes in relevant market, trading, and investment-specific considerations make the existing classification no longer reflective of the investment's actual liquidity.
The confirmation that monthly review in connection with Form N-PORT filing is a minimum — not a sufficient — frequency was based on the Commission's monitoring finding that some funds were treating monthly classification as the operative standard and were not prepared to review and update classifications between monthly intervals when market conditions changed materially, a compliance failure that directly undermines the programme's purpose of ensuring real-time awareness of portfolio liquidity conditions.
The third required element is establishment and periodic review of a highly liquid investment minimum. Funds that do not primarily hold assets that are highly liquid investments must determine and implement an HLIM — a minimum percentage of net assets that must be maintained in highly liquid investments at all times.
The HLIM determination must consider four categories of factors: the fund's investment strategy and liquidity of portfolio assets in both normal and reasonably foreseeable stressed conditions; short-term and long-term cash flow projections; holdings of cash and cash equivalents and any borrowing arrangements; and, for ETFs, the characteristics of the fund's creation and redemption process and the fund's liquidity needs in connection with that process.
The August 2024 guidance addressed specific HLIM implementation questions identified through staff monitoring, clarifying that funds must consider all four factor categories and that the HLIM must be calibrated to the fund's specific risk profile rather than set as a fixed percentage that ignores the dynamic relationship between the fund's investment strategy and its redemption risk.
The fourth required element is compliance with the 15% illiquid investment limit. A fund that breaches the 15% limit — whether due to portfolio purchases, market value changes that increase the proportion of illiquid holdings relative to net assets, or reclassification of previously liquid investments as illiquid — must take steps to reduce illiquid holdings in a manner consistent with the fund's best interests and its shareholders' best interests.
The rule does not require immediate forced liquidation of illiquid positions that cause the limit to be breached, recognising that forced liquidation of illiquid assets in response to a technical limit breach would likely harm remaining shareholders by forcing sales at depressed prices. Instead, the fund must have written policies and procedures addressing how it will manage a breach, including the timeline for returning to compliance and the reporting obligations triggered by the breach.
The fifth required element is board oversight and reporting. A fund's board of directors must approve the fund's liquidity risk management programme — including the identification of the programme administrator — and must receive periodic reports from the programme administrator addressing the operation and effectiveness of the programme, material changes to the programme, significant liquidity events, and any liquidity breaches of the 15% illiquid limit.
The board approval and ongoing reporting requirements connect Rule 22e-4 directly to the broader registered fund governance framework established by Rule 38a-1, which requires that the fund's compliance programme address the fund's compliance with all applicable securities laws including Rule 22e-4's liquidity risk management requirements.
Scope of Application
Rule 22e-4 applies to all open-end management investment companies registered or required to register under Section 8 of the Investment Company Act — encompassing conventional actively managed and index mutual funds, bond funds, hybrid funds, and Exchange-Traded Funds of all categories.
Two categories of fund are explicitly excluded: money market funds regulated under Rule 2a-7, which maintain their own comprehensive liquidity framework through the daily and weekly liquid asset minimums and portfolio quality standards of that rule; and In-Kind ETFs, defined as ETFs that transact exclusively through in-kind creation and redemption baskets with no cash component.
The In-Kind ETF exclusion reflects the Commission's recognition that these vehicles — which satisfy creation and redemption obligations entirely through delivery and receipt of portfolio securities rather than cash — do not present the same liquidity risk profile as funds that meet redemption obligations with cash.
A fund that redeems by delivering a proportionate slice of its portfolio to the redeeming authorised participant has no need to liquidate portfolio positions to raise redemption proceeds, eliminating the core liquidity transformation risk that Rule 22e-4 is designed to manage.
Exchange-Traded Funds that do have cash components in their creation and redemption transactions — the substantial majority of ETFs in the domestic market, including most equity ETFs and virtually all fixed income ETFs — are subject to Rule 22e-4's requirements, with the HLIM determination specifically required to consider the ETF's creation and redemption process characteristics and liquidity needs.
The August 2024 guidance specifically addressed ETF-specific HLIM considerations in light of examination findings suggesting that some ETFs were not adequately accounting for the unique liquidity dynamics of the creation and redemption process in their HLIM determinations.
Relationship to Related Rules and Regulations
Rule 22e-4's liquidity risk management framework is inseparable in practice from Rule 2a-5's fair value determination framework.
The liquidity classifications that Rule 22e-4 requires for each portfolio holding depend on accurate assessments of how quickly and at what market impact each investment can be sold — assessments that are directly informed by the same fair value methodologies and market data that Rule 2a-5's framework governs. A fund whose fair value process under Rule 2a-5 accurately reflects current market liquidity conditions for its portfolio holdings will be well-positioned to maintain accurate liquidity classifications under Rule 22e-4; a fund whose fair value process uses stale or inappropriate inputs may simultaneously have inaccurate fair values and inaccurate liquidity classifications, compounding the governance failure across both regulatory frameworks.
Rule 22c-1's forward pricing requirement creates the structural demand for redemption liquidity that Rule 22e-4's liquidity risk management framework is designed to ensure funds can meet. The forward pricing requirement — which requires that redemption proceeds be paid based on the next computed NAV — creates an obligation to pay cash to redeeming shareholders promptly and at a price reflecting current portfolio value.
A fund that cannot liquidate sufficient portfolio assets to generate the required redemption proceeds without moving market prices — precisely the scenario that the 15% illiquid limit and HLIM requirements are designed to prevent — would be forced to either violate Section 22(e)'s seven-day redemption requirement or make distressed portfolio sales that harm remaining shareholders through NAV dilution.
Rule 22e-4 and Rule 22c-1 therefore operate as a coordinated system — the pricing rule establishes the redemption obligation, and the liquidity risk management rule ensures the portfolio is managed in a manner that honours that obligation.
The money market fund exclusion from Rule 22e-4 connects to Rule 2a-7's comprehensive alternative liquidity framework, which addresses money market fund liquidity through the daily liquid assets minimum of 25% and weekly liquid assets minimum of 50% of total assets — liquidity standards that are more prescriptive and operationally specific than Rule 22e-4's principles-based programme framework, calibrated to the money market fund's specific role as a stable-value cash management vehicle.
Rule 6c-11's ETF framework interacts with Rule 22e-4's liquidity requirements through the ETF's creation and redemption process.
ETFs subject to Rule 22e-4 must incorporate their creation and redemption mechanics into their HLIM determinations, recognising that authorised participant creation and redemption activity is the primary mechanism through which ETF liquidity is managed and through which the ETF's obligation to honour redemptions — equivalent to an open-end fund's Section 22(e) obligation but implemented through the creation unit structure — is satisfied.
An ETF whose HLIM determination ignores the liquidity implications of its creation and redemption process has failed to implement Rule 22e-4's requirements in a manner appropriate to its specific structure.
Rule 38a-1's comprehensive compliance programme framework requires every registered fund's compliance programme to address Rule 22e-4 compliance — including the adequacy of the fund's liquidity classification methodology, the robustness of the HLIM determination process, the procedures for managing breaches of the 15% illiquid limit, and the board reporting infrastructure through which Rule 22e-4's governance requirements are implemented. The interconnection between Rule 22e-4 and Rule 38a-1 reflects the Commission's determination that liquidity risk management is a compliance function deserving the same comprehensive governance infrastructure that Rule 38a-1 establishes for all aspects of registered fund regulatory compliance.
Amendment History and Regulatory Evolution
Rule 22e-4's operative framework has remained in its October 2016 adopted form, with the February 2018 compliance date extension making the only formal amendment to the rule's text.
The most consequential post-adoption development was the November 2022 proposal — which would have substantially restructured the liquidity classification framework by requiring funds to assume stressed liquidity conditions when classifying holdings, mandated swing pricing for all non-ETF, non-money-market funds, and imposed a hard close requiring all orders to reach funds directly rather than through intermediaries — and its subsequent effective withdrawal reflected in the August 2024 release that adopted only the Form N-PORT and N-CEN amendments from the 2022 proposal without the Rule 22e-4 programme amendments.
The August 2024 guidance — addressing intra-month classification review frequency, the cash definition excluding foreign currencies, and HLIM determination considerations — represents the Commission's most substantive engagement with Rule 22e-4 programme implementation since the original adoption, providing authoritative direction on areas where monitoring had revealed systematic compliance gaps without requiring formal rule amendment.
This guidance-based approach reflects the Commission's recognition that the identified compliance issues could be addressed through interpretation of the rule's existing requirements rather than through the more disruptive process of formal rule amendment with new compliance timelines.
Enforcement Context and SEC Action Patterns
Rule 22e-4 enforcement has proceeded through two primary channels: formal enforcement actions against funds whose liquidity risk management programmes failed to satisfy the rule's core requirements, and the Office of Examinations' liquidity-focused examination programme that has identified specific compliance deficiencies addressed in part through the August 2024 guidance.
The Commission has brought enforcement actions against registered funds and their investment advisers for Rule 22e-4 violations including inadequate liquidity classification processes — particularly the use of standardised or generic liquidity classifications that did not reflect the fund's actual assessment of individual investment liquidity in current market conditions; failure to maintain written records supporting liquidity classification decisions; inadequate HLIM determinations that did not consider all required factors; and failure to have procedures for managing 15% illiquid limit breaches.
The Division of Examinations identified Rule 22e-4 compliance as an examination priority and its monitoring found that multiple funds were not prepared to review and update liquidity classifications on an intra-month basis in response to market changes — a compliance gap that the August 2024 guidance specifically addressed by reaffirming the requirement for intra-month review capability and confirming that monthly classification review in connection with Form N-PORT filing is a minimum frequency standard rather than a complete compliance framework.
Examination Relevance and Key Takeaways
Rule 22e-4 is examined at the Series 65 level as the liquidity risk management framework for open-end registered funds. The four liquidity classification categories — highly liquid, moderately liquid, less liquid, and illiquid — and their time-based definitions are the primary structural examination content.
The 15% illiquid investment limit — the rule's single hard quantitative ceiling — is consistently examined as the operationally definitive constraint that applies universally to all funds subject to the rule regardless of investment strategy.
The exclusions of money market funds under Rule 2a-7 and In-Kind ETFs from Rule 22e-4's requirements are examined in the context of understanding the differentiated liquidity governance framework that applies across different registered fund categories — money market funds through Rule 2a-7's prescriptive liquidity minimums, In-Kind ETFs through their inherent structural liquidity management, and all other open-end funds through Rule 22e-4's principles-based programme framework.
The key points to retain are these. Rule 22e-4 requires every open-end management investment company — excluding money market funds under Rule 2a-7 and In-Kind ETFs — to adopt and implement a written liquidity risk management programme encompassing five elements: overall liquidity risk assessment; classification of each portfolio investment into one of four categories — highly liquid (convertible to cash in three business days or less without significant market impact); moderately liquid (three to seven calendar days); less liquid (capable of being sold in seven days but settlement extends beyond that period); and illiquid (cannot be sold in seven days without significantly changing market value); establishment and periodic review of a highly liquid investment minimum for funds not primarily holding highly liquid assets; a hard limit prohibiting more than 15% of net assets in illiquid investments; and board approval and periodic reporting on programme operation. Cash for Rule 22e-4 purposes means U.S. dollars and does not include foreign currencies.
Liquidity classifications must be reviewed and updated intra-month as market conditions change, not merely monthly in connection with Form N-PORT filing. ETFs subject to the rule must incorporate their creation and redemption process characteristics into their HLIM determinations.
Rule 22e-4 was adopted October 2016 and remains operative in its current form. The August 2024 release provided substantive guidance on classification frequency, cash definition, and HLIM determination while adopting Form N-PORT and N-CEN amendments.
