agreements and other short-term assets.

As shown in Figure 5, EU MMFs are mainly exposed to the financial sector including credit institutions, whose securities amount to more than 60% of total money market instruments held by EU MMFs. Exposures to non-financial corporates remain limited (10% of money market instruments) and are mainly held by VNAVs.28 In aggregate, EU MMFs hold between 50 and 70% of euro-denominated financial commercial papers and negotiable certificates of deposit29 (FSB, 2021).

As shown in Figure 6, most of the public debt exposure of EU MMFs is towards non-EU sovereigns (74% of sovereign exposure at the end of 2021). Those exposures are mainly held by CNAVs. The latter significantly reduced their government bond holdings from 62% of total assets in June 2021 to 32% in June 2022. Simultaneously, they increased their repo market exposures, driven by the expectation of changing interest rates. The share of government bonds in the portfolios of LVNAVs has increased significantly over 2020, but was readjusted to the pre-COVID-19 composition over 2021 and the first half of 2022. VNAVs normally have a lower share of government debt, on average 7% of their assets.30

3. Recent market developments and lessons learned

In the recent years, several stress events have taken place that have tested the framework for MMFs. In March 2020, the COVID-19 pandemic led to a sudden increase in demand for safe and liquid assets in both the financial and non-financial sectors. Market liquidity deteriorated considerably across a broad range of markets and prompted unprecedented interventions by central banks. The value of major stock market indices dropped over 30% within several weeks and financial markets experienced a significant increase in volatility during the first months of the pandemic. Due to the general uncertainty, investors were hesitant to invest in financial markets, which led to vast valuation losses.

Corporate bonds and MMFs also experienced significant stress. Corporate bond yields rose significantly during February and March 2020. MMFs exposed to private markets, i.e. LVNAVs and VNAVs in the EU and prime MMFs in the US31, recorded high outflows. EU-domiciled LVNAVs experienced outflows of EUR 51.4 bn during March 202032 and faced challenges to sell their commercial papers and certificates of deposit as banks were unwilling or unable to buy back these papers, including their own papers.33

The stress was particularly acute for USD-denominated LVNAVs, as shown in figure 7 and relevant literature.34 As their weekly maturing assets (WMA) holdings approached the regulatory minimum of 30%, some investors may have been concerned about the increasing possibility that fund managers would make use of available liquidity management tools (i.e. liquidity fees or redemption gates). Concerns about the use of liquidity management tools were particularly acute in the US market, which may be explained by the fact that EU investors are by and large more comfortable with fees than US investors, due to their familiarity with fees under UCITS. As shown in Figure 7, this resulted in a spill-over effect to EU-domiciled MMFs, with a combination of redemptions in USD LVNAVs and subscriptions in USD Public Debt CNAVs of a similar magnitude, reflecting a potential substitution effect (or flight-to-quality).

The data35 shows that MMFs with low WMAs recorded higher outflows than MMFs with high WMAs. This analysis can be interpreted as evidence that institutional investors redeemed from MMFs to avoid being subject to fees and gates. Additionally, studies by Avalos and Xia (2021)36, Darpeix (2021)37 and Dunne and Giuliana (2021)38 show that the liquidity ratios were key drivers of redemptions in the case of LVNAVs, but not in the case of VNAVs, thus pointing at possible undesirable threshold effects.39 Given the magnitude of the crisis and the global economic situation triggered by the pandemic, major central banks took a range of actions to support capital markets. Such support took place through:

- outright purchases of domestic-currency denominated certificates of deposit and commercial papers (ECB,40 Bank of England41, Federal Reserve) on the primary or on the secondary market,

- extending the eligible collateral to unsecured bonds issued by banks (ECB)

- and lending facilities for banks to buy assets from MMFs (Federal Reserve).42

As a result of the intervention of central banks, redemption requests slowed down and liquidity improved in underlying money markets. While these interventions primarily aimed at restoring confidence in the depth and liquidity of short-term funding markets, they also indirectly benefitted EU MMFs.

The market turmoil of March 2020 showed that some financial market segments were unable to absorb significant and sudden increases in selling pressures. This was perhaps also because the liquidity supply by dealers was more constrained and less responsive to sudden increases in demand than before the 2008 financial crisis. Nevertheless, no EU MMF had to introduce redemption fees or gates or to suspend redemptions in March 2020. Moreover, no LVNAV exceeded the thresholds set out in the MMF Regulation to be converted into VNAV (the deviation of the market NAV from the constant NAV came close to the 20 basis point collar for some USD LVNAVs). However, these results should be interpreted cautiously and put into context given the central bank interventions that supported the markets.

Since February 2022, Russia’s invasion of Ukraine and the related geopolitical tensions have impacted financial markets, most notably commodity prices and related derivative products. Since EU MMFs invest in highly liquid, short maturity assets with minimal credit risk, they did not experience significant losses or outflows. MMFs have adapted to the situation by readjusting their holdings towards even shorter maturity instruments, which are less exposed to interest rate risk43 and by increasing their liquidity. There are some signs of indirect impact of investors selling other assets or facing margin calls and tapping EU MMFs to store or access liquidity. However, inflows and outflows seemed rather balanced and no EU MMF had to introduce redemption fees or suspend redemptions in this situation.

In September 2022, the market stress experience in the UK also impacted those EU MMFs with a sizeable exposure to UK assets and/or having UK investors (notably Irish MMFs, which have approximately 60% of their investor base by amount owned from the UK). According to available evidence, there was an indirect impact on GBP-denominated MMFs, linked mainly to investors needing to quickly access liquidity following increased margin calls and forced sales, notably by funds with liability-driven investment strategies.44 Some GBP-denominated MMFs saw increased outflows (five funds experienced cumulative outflow of more than 10%)45 shortly after the announcement of the UK “mini budget” on 23 September 2022.

The situation quickly reversed following the intervention of the Bank of England to support the gilt market. In October 2022, GBP-denominated EU MMFs experienced inflows of nearly 30%. Moreover, during the last week of September 2022, GBP-denominated EU MMFs took steps to strengthen their resilience, having increased the proportion of liquid assets in their portfolios, with both daily and weekly liquidity levels rising significantly.46

While one LVNAV fund came close to breaching the regulatory limit for NAV deviation, it seems that the sector overall held well and delivered on its role of providing short-term liquidity storage. The liability-driven investment episode highlights the role of MMFs as liquidity management vehicles for institutional investors. It also shows the importance of preserving the resilience of the MMF sector to different types of economic shocks.

In March 2023, no significant impact on EU MMFs was observed following the turmoil in the banking sector. In the US, the collapse of Silicon Valley Bank led some depositors to question the safety of bank deposits, notably those above the regulatory protection limit. This triggered a shift towards US MMFs, which offered higher yields and better flexibility. Moreover, the banking turmoil resulted in increased inflows in the Federal Reserve overnight reverse repo (ON RRP) facility during the last weeks of March 2023. Following the takeover of Credit Suisse by UBS, EU MMFs have also seen sizeable inflows, including EUR 17.7 bn into euro-denominated MMFs during March 2023, which could be seen as an indication that market participants perceive the EU MMF sector as resilient.

3. ADEQUACY OF THE MMF REGULATION FROM A PRUDENTIAL AND ECONOMIC POINT OF VIEW

The following section reviews the adequacy of the MMF Regulation from a prudential and economic point of view, according to the requirements of Article 46(2) of that Regulation.

MMFs are a distinct category of investment funds, closely intertwined on the one hand with firms active in the real economy and the banking sector and on the other with key parts of the financial markets. They have an important dual economic function as a liquidity- and cash management tool and as a short-term funding instrument for financial and non-financial entities. They are not homogeneous, and their structure and risk characteristics differ across jurisdictions.47


1. MMFs and debt issued or guaranteed by EU Member States.

Article 46(2)(b) and (c) of the MMF Regulation requires the Commission to assess the role that MMFs play in purchasing debt issued or guaranteed by the Member States and to take into account the characteristics of such debt and the role that it plays in financing the Member States.

Because of the comparatively low liquidity and long maturities of debt instruments issued or guaranteed by EU Member States, EU MMFs do not invest significantly in such securities. Instead, most of the government debt exposure of EU MMFs is towards non-EU sovereigns (EUR 119 bn at the end of 2021, 74% of total sovereign exposure). In particular, US government debt accounts almost entirely for the sovereign debt holdings of CNAVs (EUR 88 bn at the end of 2021). For LVNAVs, EU government debt accounted for 36% of their exposure to government bonds at the end of 2021, while UK and US sovereigns accounted for around 60%. In contrast to other MMF types, the majority of government debt holdings of VNAVs are EU instruments, representing more than 75% of their government debt exposure at the end of 2021.48 However, VNAVs generally have a lower share of government debt compared with other types of MMFs (only 7% of their assets).


Under the MMF Regulation, government debt with a longer residual maturity49 may still count for up to 17.5 percentage points of the 30% required weekly maturing assets for LVNAV or public debt CNAV. Respondents to the consultation indicate that the cap of 17.5% appears inconsistent with the treatment of sovereign debt in other legislative frameworks (section 3.2). However, the MMF Regulation allows MMFs to invest up to 100% of their assets in sovereign debt and the limitations focus solely on liquidity buffers of LVNAV and public debt CNAVs due to the longer maturity and higher volatility of those assets compared with weekly maturing assets. Respondents to the consultation also indicate that many investors use public debt CNAVs due to an unwillingness or inability to invest in credit portfolios. This is commonly due to specific collateral, capital or regulatory requirements, e.g. requirements that cash positions be collateralised only with government debt, or regulatory requirements like high-quality liquid assets. Other investors indicate that while investments in public debt CNAV are done for diversification purposes, the size of these markets is not big enough to meet the cash management needs of some investors.



2. Uniform definitions of high and of extremely high liquidity and credit quality of transferable assets

Article 46(2)(d) of the MMF Regulation requires the Commission to take into account the report referred to in Article 509(3) of Regulation (EU) No 575/2013.

Article 509(3) of Regulation (EU) No 575/2013 tasked the EBA to report to the Commission on appropriate uniform definitions of high and of extremely high liquidity and credit quality of transferable assets. Banks invest in these assets to comply with the regulatory liquidity requirements under rules defined by the Basel Committee on Banking Supervision.


The EBA issued this Report on 20 December 2013,50 while recommending that its empirical conclusions should be supplemented by a qualitative/expert judgment, also building on supervisory advice. Based on the empirical analysis of a wide range of financial assets traded in the EU, the EBA distinguished between assets of high liquidity and quality and assets of extremely high liquidity and quality. In line with international standards, the EBA recommended to consider all bonds issued or guaranteed by European Economic Area sovereigns and central banks in the domestic currency and also those issued or guaranteed by supranational institutions as transferable assets of extremely high liquidity and credit quality.


Liquidity risk management for asset managers incorporates a range of safeguards: staggered maturities in particular for less liquid assets, daily and weekly liquidity buckets depending on the maturity of the assets in the portfolio, rules on the credit quality of assets, knowledge of the MMF investors base, and rules on the behaviour and liquidity of the assets and their correlation. Since 2017, increased attention has been paid to strengthening the management of liquidity risk, including by working on MMF stress testing, transparency and supervision, the definition of liquid assets, and the eligibility of assets for liquidity requirements.


Under EU asset management rules, the liquidity of an asset cannot be automatically presumed, and an appropriate liquidity test must be performed. For this purpose, asset managers have to put in place an appropriate risk management process, which is systematically reviewed and adapted to their investment strategies and to the type of investors (‘know your costumer‘ policy). The liquidity and credit quality are measured on a case-by-case basis at the level of the financial instruments and of the overall portfolio.

Therefore, while some assets may be considered of high or extremely high liquidity under the EU banking framework, this may not automatically be the case in an MMF context, and a case-by-case analysis would be required to determine the liquidity and credit quality of a fund’s assets.


3. Impact of the MMF Regulation on short-term financing markets

Article 46(2)(e) of the MMF Regulation requires the Commission to take into account the impact of this Regulation on short-term financing markets.

MMFs are part of the broader ecosystem of short-term finance. The turmoil in March 2020 revealed certain structural vulnerabilities, data gaps, and regulatory uncertainties on European short-term funding markets. While these are beyond the scope of the MMF Regulation, they remain important for the sound functioning of EU MMFs.


The short-term funding market is an over-the-counter dealer intermediated market. There is evidence that this short-term funding market is fragmented and opaque.51 Relevant information is spread over multiple trading venues, neither of which is able to provide a comprehensive picture of the market due to partial reporting, unclear scope of action, inconsistent terminologies, etc.


The study also shows that secondary market activity (bid, offer, price, volumes, etc.) is almost entirely opaque. This makes price discovery challenging, creates inefficiencies in these markets, and leads to difficulties for MMFs to appropriately monitor risks in a stress situation. It also prevents regulators from accurately assessing structural market liquidity. Increased transparency could contribute to making short-term funding markets more dynamic and more resilient, thereby also reducing the risk associated with MMFs in case of severe stress.


Most respondents to the consultation, including financial sector respondents and supervisors, pointed to the need to increase transparency and to help price discovery in the short-term securities markets, by requiring more disclosures on what is being traded and on outstanding amounts.


Furthermore, given the lower liquidity and opacity of this market, there is a risk that a market stress can be transmitted to other MMFs in what is called a contagion dynamic. In order to satisfy redemption requests, MMFs need to invest in sufficiently liquid assets. Such liquid instruments include reverse repos (often overnight), Treasury bills, and bank deposits. Other instruments (certificates of deposit, commercial papers) cannot always be sold off quickly (as they are normally held until maturity and secondary markets are not sufficiently deep, heightening the price impact if they are sold), but they have a very short maturity. If a run occurs, MMFs would first use the proceeds of maturing assets or terminate their reverse repo transactions to meet redemption requests. If the run continues, MMFs would sell their liquid assets without further investing in short-term instruments leading to a sudden drying of sources of funding for companies.


In principle, this contagion dynamic would be avoided if MMFs could invest their cash in instruments for which a rapid withdrawal would not lead to market contagion. One instrument that satisfies this requirement would be a deposit at the central bank itself. A case study of such an arrangement can be found in the US, where MMFs may place their excess cash with the US Federal Reserve’s overnight reserve repo (ON RRP) facility. In addition to preventing contagion dynamics in situations of liquidity crunch, this facility also puts the US MMF sector at an advantage compared to EU MMFs in terms of flexibility in managing their liquidity inflows.52 This was exemplified by the banking crisis sparked by the collapse of Silicon Valley Bank which lead to an increase of inflows to US MMFs, resulting in a subsequent growth in the usage of the Federal Reserve’s facility during the last weeks of March 2023. By March 2023, MMFs and other eligible participants held more than USD 2.3 trillion in that facility.53



4. Regulatory developments at international level

Article 46(2)(f) of the MMF Regulation requires the Commission to take into account the regulatory developments at international level.

Pandemic related events triggered a strong push to further strengthen the regulatory framework for MMFs. This has resulted in several proposals by ESMA, the ESRB, and the FSB to reform the regulatory framework for MMFs, to limit systemic risks and to ensure that the MMF sector can withstand a potential future liquidity or market stress. The policy options proposed by the different authorities and institutions can be grouped as follows: (1) reduce the risk of runs (notably by removing the deposit-like features of certain MMFs), (2) strengthen the liquidity of MMFs and their ability to absorb losses, and (3) measures to prepare for future crises. These proposals are listed in Table 2 and further detailed below.

(*) proposal to require a minimum holding in highly liquid assets including public debt and maximum holding of assets with lower liquidity under stressed market (e.g. 40% in private sector certificates of deposit and commercial paper).

(**) The Bank of England and the Financial Conduct Authority are contemplating launching a consultation on the removal of the stable NAV from LVNAVs. LVNAVs would have similar rules as short term VNAVs. They also consider limiting the size of the public debt CNAV market.




1. Reducing the risk of runs

International organisations and supervisory bodies such as the ESRB and ESMA have recommended that LVNAVs become variable NAV funds, following the example of the US.54 Such a change would aim at reducing the risk of runs caused by threshold effects by limiting opportunities for investors to redeem from the MMF at constant prices which in periods of market stress do not necessarily reflect current market valuations of underlying assets. To this end, they propose to prohibit the use of amortised cost accounting and the associated 2nd decimal rounding which allows LVNAVs to offer a stable redemption price.

However, this policy option would imply a radical change for the EU MMF market and notably the disappearance of the LVNAV market. The switch from a stable to a variable NAV would remove the deposit-like features of these products, which is one of the main purposes that investors cite for using these MMFs. The majority of the respondents to the consultation were rather critical about removing LVNAVs. Most respondents saw the risk that in this case, some investors would exit the MMF market. The limited availability of economically viabile alternatives and substitutes to LVNAVs could lead investors to turn to less regulated products.

As an alternative, current investors in LVNAVs could invest in public debt CNAV (currently 11% of the market), in floating NAV MMFs (in particular short-term VNAV) or directly in the short-term market. However, responses to the stakeholder consultation indicate that the public debt CNAV segment is too small to accommodate the cash management needs of investors and that it does not meet their liquidity requirements. Moreover, respondents indicate that the elimination of LVNAVs would result in an increase in competition for government assets, which are used by banks as High Quality Liquid Assets, as well as by many other investors for liquidity management purposes.

Some respondents indicate that short-term VNAV could be an alternative, but point to uncertainties about their accounting treatment as ‘cash and cash-equivalent’ in different jurisdictions. Moreover, such changes would also have tax implications. Most respondents to the consultation indicate that they would use bank deposits as alternative instruments in case LVNAVs were no longer available, even though bank deposits would result in an increase of counterparty credit risk and significantly reduce risk diversification compared with the diversified portfolios provided by MMFs.

Overall, the respondents to the consultation appreciated the utility of LVNAVs and particularly the operational ease of use for investors because of the ability to round the share price within the 20 basis points collar. Should LVNAVs not be available anymore, respondents feared a lack of alternative investment and risk diversification options. The resilience of LVNAVs during the March 2020 turmoil should also be taken into consideration, as no LVNAVs activated liquidity management tools nor did they convert into VNAVs during this period.



2. Strengthen the liquidity of MMFs and their ability to absorb losses

Prudential and supervisory bodies have put forward a range of policy options aiming at further strengthening the ability of MMFs to face high redemption requests and protect public interest and financial stability.

While the connection between the use of LMTs and liquidity levels is not automatic in the MMF Regulation, a breach of minimum WMA holdings of 30% can potentially trigger the imposition of redemption gates or fees. This seems to have compelled fund managers not to use their WMA holdings to finance increased redemption requests in March 2020, fearing that a breach of the minimum WMA level would induce further redemption requests as investors anticipated the imposition of liquidity management tools. Fully disconnecting the potential use of LMTs from breaches of minimum liquidity holdings could thus increase the ability of fund managers to finance increased redemptions in stress periods. This proposal finds the largest support so far among stakeholders.

The proposal to relax existing limits on eligible public debt assets as part of liquidity buckets is strongly supported by the ECB, which wants investments in these assets to be made compulsory. Views of stakeholders are split when it comes to the binding character and levels of investments in such assets. This is related to the variable impact of such investments on the profitability of MMFs and the availability of eligible public debt. Stakeholders also express some concerns about shifting liquidity risk to the sovereign market. Although public debt can serve as a crucial tool to manage liquidity for MMFs, the recent UK crisis has shown that it is not immune to episodes of price volatility. In addition, there is a risk that an increase in the existing limits on eligible public debt assets would result in MMF investments becoming overly concentrated in these securities, whereas the diversification of investments in different asset classes is an important safeguard.

More generally, the proposals to increase minimum holdings of liquid assets, while not controversial in substance, are difficult to implement and may have unintended consequences. Indeed, while the rules on liquidity coverage ratio provide for a definition of high quality liquid assets, in the asset management sector it is difficult to define liquid assets (e.g. government bonds may also face stressed market conditions). In addition, MMF managers manage liquidity with a holistic approach including staggered maturities, use of reverse repo transactions and the characteristics of their investor base (including investor concentration). Moreover, additional hard thresholds would introduce rigidity in the implementation of asset managers’ liquidity risk management policies, including stress tests, with potential unintended effects.

There are split views among stakeholders, based on the role and function of MMFs, about the actual impact of recommendations to give fund managers the possibility to shift the cost of redemptions to investors (by imposing different kinds of price-based liquidity management tools, also known as swing pricing), as recommended by the FSB and the ESRB and put forward by the US Securities and Exchange Commission. Following the FSB and ESRB recommendations, the proposal to revise the directives on Alternative Investment Fund Managers (AIFMD) and UCITS aims to expand the range of liquidity management tools for funds in the EU and to harmonise the ways they are used. EU MMFs will benefit from the AIFMD/UCITS review, whereby asset managers would be allowed to select the most appropriate liquidity management tools from a dedicated list.

Proposals to increase the loss-absorption capacity of MMFs have been put forward by the FSB, including by imposing constraints on the shares that can be redeemed immediately (this is known as ‘minimum balance at risk’) and by requiring MMFs to maintain capital buffers, for example outside the MMF in an escrow account financed by fund managers. These types of solutions would reduce the first mover advantage for investors, as they would mitigate the risk of losses being imposed on remaining investors. However, such solutions are either untested and contingent on significant operational adjustments (for ‘minimum balance at risk’), or they would make it more expensive to operate MMFs and thus likely lead to closures of some funds (for capital buffers) and lower returns for investors.



3. Other measures

A number of additional measures, which are not directly linked to the operations of MMFs, have also been put forward by ESMA and the FSB, and merit further assessment. Those are mainly related to reporting and stress testing. Similarly, other proposals from stakeholders such as strengthening supervision could be further assessed.


5. Feasibility of establishing a minimum 80% EU-public debt quota

Article 46(2) of the MMF Regulation requires the Commission to assess the feasibility of establishing an 80 % EU public debt quota.

This report takes account of the availability of short-term EU public debt instruments and assesses whether LVNAVs might be an appropriate alternative to public debt CNAVs targeting instruments in other currencies.

Recital 56 of the MMF Regulation argues that such a quota may be “justified from a prudential supervisory point of view”, given that “the issuance of EU short-term public debt instrument is governed by Union law”. However, there are two main difficulties that render such a quota unfeasible in practice.

The first difficulty is the mismatch between, on the one hand, the public debt CNAVs currently available in the EU (which are mostly denominated in USD or GBP, with only one relatively small EUR-denominated public debt CNAV in existence55), and on the other hand, the denomination of public debt in the EU. Data from Darpeix56 shows that the vast majority (around 90%) of short-term debt securities issued by EU countries (whether or not they belong to the euro area) is labelled in EUR, with only around 5% denominated in USD. The mismatch between the denominations of the funds themselves and the available public debt instruments implies that EU public debt CNAVs mainly invest in US- and UK-issued instruments.57

The results of the public consultation indicate that even with the imposition of an EU public debt quota investors in USD and GBP denominated CNAVs would likely not shift to EUR-denominated public debt MMFs, for two main reasons.

- First, because clients mainly take into account sovereign and currency risk aspects together. For instance, clients investing in USD-denominated MMFs want to have exposure to US debt and currency rather than to EU debt and currency. This is also closely related to the economic function of MMFs as a store of liquidity in a given currency.

- And second, because there are risks related to low diversification and relatively low liquidity of EUR-denominated short-term public debt. Feedback from stakeholders indicates that MMFs prefer to invest in assets with maturity lower than 3 months, which is difficult to achieve with the current market for EUR-denominated public debt.

The second difficulty is that such a quota could have negative financial stability implications. Banks need exposure to government debt to comply with the Basel II liquidity requirements. A minimum 80% EU-public debt quota would mean that MMFs would target the same instruments as banks. As a result, there would be a multitude of investors investing in the same asset class, thus increasing risks of contagion and financial instability in crisis situations due to common underlying exposures amplifying a feedback loop between financial and sovereign risk.

In light of the preceding analysis, the merits of establishing a minimum 80% EU-public debt quota for EU MMFs remain questionable. However, even without the imposition of a quota, more EUR-focused public debt CNAVs might appear in the market following the recent increase in interest rates in the euro area, which could help place more short-term sovereign debt in EUR with EU public debt CNAVs.
4. CONCLUSIONS

This report delivers on the legal mandate under Article 46(1) and 46(2) of the MMF Regulation for the Commission to submit a report to the European Parliament and to the Council, reviewing the adequacy of the MMF Regulation from a prudential and economic point of view.

The report shows that the MMF Regulation successfully passed the test of liquidity stress experienced by MMFs during the COVID-19 related market turmoil of March 2020, the recent interest rate increases, and related financial asset re-pricing. No EU-based MMF had to introduce redemption fees or gates or to suspend redemptions during these stress events. Similarly, EU MMFs focused on GBP assets withstood the redemption pressure linked to the September 2022 gilt market stress.


These experiences indicate that the the safeguards in the MMF Regulation have been working as intended. This includes the safeguards that were conceived to allow stable NAV MMFs (CNAVs and LVNAVs) to continue using, under certain conditions, the amortized cost method without creating systemic risks and harming investors.


By introducing a dedicated regime, the MMF Regulation has significantly strengthened the regulatory framework for MMFs in the EU, which had before been subject to different rules. However, after 5 years of application of the MMF Regulation, this report identifies shortcomings which should be further assessed. In particular, the results of the stakeholder consultation and the recent market developments show that there could be scope to further increase the resilience of EU MMFs, notably by decoupling the potential activation of liquidity management tools from regulatory liquidity thresholds. In addition, this report highlights structural problems that are external to MMFs, and therefore also to the MMF Regulation, including those linked to the underlying short-term markets. These structural problems would merit a further assessment, and are also currently the subject of a more in-depth analysis at the level of FSB.

Finally, EU MMFs will benefit from the ongoing review of the AIFM and UCITS Directives58, which aims to introduce new harmonised rules to increase the availability of LMTs for open-ended funds. This new LMT framework will further strengthen the resilience of EU MMF’s liquidity management in cases of stress.

16 The distinguishing feature of Public Debt CNAV and LVNAV is NAV rounding to the 2nd decimal, which is however only possible within the 20bp corridor for LVNAVs (vs. the 4th decimal for VNAVs). The rounding means that investors do not need to recognise the very small unrealised capital gains and losses in the portfolio when they redeem shares.

17 The MMF Regulation imposes a number of other portfolio and valuation rules which aim at investor protection and stability of financial market.

33 Commercial papers and certificates of deposit are usually held to maturity and even if they have very short maturity, their secondary market is not liquid, even in normal times. Meanwhile, MMFs account for a significant proportion of demand for these instruments.

34 As discussed in various reports including the FSB’s Policy proposals to enhance money market fund resilience from October 2021, ESRB’s Issues note on systemic vulnerabilities of and preliminary policy considerations to reform money market funds (MMFs) from July 2021, and ECB’s article from April 2021 Macro-prudential bulletin, titled “How effective is the EU Money Market Fund Regulation?

40 In March 2020, the ECB announced further support for euro money markets by extending its existing corporate sector purchase program to include euro-denominated non-financial commercial paper with remaining maturities of as few as 28 days (reduced from an earlier 6 months minimum). The ECB’s corporate purchase programme thus benefitted local-currency MMFs only indirectly by contributing to restoring confidence in the underlying EUR-denominated markets.

42 Nevertheless, EU USD LVNAVs were not eligible for the ECB facilities and the Federal Reserve’s MMLF and they initially suffered outflows but have rapidly recovered after the central bank announcements.

43 Assets with a lower duration face a smaller change in price following a shock in interest rates. On average, MMFs have significantly reduced their average weighted maturity, down to a 10-year low of 19 days from previous levels close to 50 days in late 2020 and 2021.

44 These strategies have been notably used by defined-benefit pension funds, which have used leverage to be able to match their assets and liabilities in a low interest rate environment.

52 The decision about opening such a liquidity facility to MMFs however is beyond the competencies of the European Commission and lies in the ECB remit.

54 The US SEC made this move in 2016. The SEC reform required all institutional prime MMFs (that is non-government MMFs used by institutional investors) to convert to variable NAV. The result of this reform is that assets invested in these US MMFs contracted substantially in the years leading up to the implementation of these reforms, to the benefit of US government MMFs (which have a stable NAV feature).

57 For various reasons, MMFs tend not to mix currencies. While they could do so to some extent by hedging currency risk exposures via foreign-exchange derivatives, it would become too costly on a substential basis.

58 As MMFs operating in the EU have to be established and comply with either AIFMD or UCITSD. The Commission proposal can be seen at: https://ec.europa.eu/info/law/better-regulation/have-your-say/initiatives/12648-Financial-services-review-of-EU-rules-on-alternative-investment-fund-managers_en.
