Monthly Reports by Money Market Funds — Form N-MFP
SEC Rule 30b1-7, codified at 17 C.F.R. § 270.30b1-7 under the Investment Company Act of 1940, requires every registered open-end management investment company that is regulated as a money market fund under Rule 2a-7 to file a monthly report of portfolio holdings and operational information on Form N-MFP with the Commission no later than the fifth business day of each month, current as of the last business day of the preceding month.
Form N-MFP — the money market fund's dedicated monthly portfolio reporting form — collects position-level portfolio data, fund classification information, liquidity metrics, yield and maturity characteristics, large shareholder information, and securities sold during the reporting period in a structured, machine-readable format that enables the Commission to monitor money market fund portfolio composition, liquidity conditions, and systemic risk concentrations on a near-real-time basis across the full universe of registered money market funds.
Rule 30b1-7 and Form N-MFP are specifically designed for the money market fund context — a regulatory environment whose systemic significance, rapid portfolio turnover, and critical role in short-term funding markets requires a dedicated, high-frequency, comprehensive reporting framework distinct from the Form N-PORT monthly reporting obligation that Rule 30b1-9 imposes on other registered management investment companies. The July 2023 Money Market Fund Reforms rulemaking — which adopted the most significant amendments to Rule 2a-7 in the rule's post-financial crisis regulatory history — substantially expanded Form N-MFP's reporting requirements, adding new disclosure items covering large shareholder information and securities sold during the reporting period, effective June 11, 2024, to give the Commission the comprehensive, transaction-level data necessary to monitor the systemic liquidity dynamics that the reformed Rule 2a-7 framework is designed to address.
Overview and Regulatory Purpose
Money market funds occupy a systemically critical position in the short-term funding markets that distinguishes them from all other categories of registered investment company and that justifies a dedicated, high-frequency, comprehensive reporting framework beyond what the general Form N-PORT regime provides.
A money market fund's portfolio typically turns over completely within 60 days — the Rule 2a-7 weighted average maturity limit — meaning that monthly portfolio disclosures reveal not only the fund's current holdings but also the near-complete replacement of those holdings since the prior month's report.
This high portfolio turnover rate, combined with the money market fund's critical intermediary function in channelling investor capital into the short-term debt markets that finance corporate operations, government activities, and interbank lending, means that the aggregate portfolio composition of the money market fund industry provides a real-time window into the health and stress conditions of the broader short-term funding markets.
The Commission's use of Form N-MFP data extends significantly beyond individual fund monitoring. The aggregate composition of money market fund portfolios — the distribution of holdings across commercial paper issuers, government securities, repurchase agreement counterparties, and municipal securities — provides the Commission and the Financial Stability Oversight Council with near-real-time data about systemic concentration risks, the flow of short-term capital to specific categories of borrower, and the emergence of redemption pressures that might signal developing stress conditions in the broader short-term funding market before that stress becomes visible through market price movements.
The March 2020 COVID-19 liquidity stress event — during which Form N-MFP data revealed that institutional prime funds were selling long-term securities at rates three times their historical monthly averages — demonstrated the value of high-frequency money market fund reporting as an early warning system for systemic funding market stress.
Statutory Authority and Rulemaking History
Rule 30b1-7 derives its statutory authority from Section 30(b) of the Investment Company Act of 1940, which authorises the Commission to require registered management investment companies to file such periodic, special, and other reports as the Commission may prescribe.
Section 30(b)'s broad periodic reporting authority is the foundational statutory basis for the Commission's prescription of Form N-MFP as the monthly reporting instrument specifically applicable to money market funds.
Form N-MFP was originally adopted as part of the Commission's 2010 money market fund reform rulemaking — Investment Company Act Release No. IC-29132 — which introduced monthly portfolio reporting for money market funds as a companion to the substantive Rule 2a-7 amendments adopted in response to the 2008 Reserve Primary Fund crisis.
Prior to the 2010 reforms, money market funds were not required to file monthly portfolio data with the Commission, a gap that had significantly impaired the Commission's ability to monitor aggregate money market fund portfolio conditions during the 2008 crisis. Rule 30b1-7 was established as the operative rule mandating Form N-MFP filings as part of that 2010 reform.
Form N-MFP was substantially amended as part of the July 2023 Money Market Fund Reforms rulemaking — Investment Company Act Release No. 34-97860, published at 88 FR 51404, August 3, 2023 — with the Form N-MFP and Form N-CR amendments effective June 11, 2024. The 2023 amendments added significant new disclosure categories to Form N-MFP, most importantly information about the fund's large shareholders — defined as shareholders holding more than 5% of the fund's outstanding shares — and detailed data about securities sold during the reporting period, including information about whether sold securities were sold before their stated maturity.
These additions directly responded to the Commission's identification, in its analysis of the March 2020 COVID-19 stress event, of large institutional shareholder redemption activity as a primary driver of the liquidity stress that affected institutional prime money market funds during that period.
A November 2024 conforming amendment — Investment Company Act Release No. IC-35324, published at 89 FR 91636, November 18, 2024 — corrected an error in the yield calculation formula in Form N-MFP's Item A.19 and B.8 instructions. The error had inadvertently substituted a 7-business-day period for a 7-calendar-day period in the annualisation formula, which would have caused funds using the erroneous formula to overstate their annualised yields.
The correction restored the intended 7-calendar-day period consistent with pre-amendment practice. No changes have been made to Rule 30b1-7's operative provisions since the 2023 amendments beyond this technical form correction.
Key Provisions and Operative Requirements
Rule 30b1-7's operative text establishes that every registered money market fund must file Form N-MFP no later than the fifth business day of each month, reporting portfolio holdings as of the last business day or any subsequent calendar day of the preceding month.
The fifth-business-day filing deadline is substantially more rapid than the filing deadlines applicable to other registered fund monthly or quarterly portfolio reports — Form N-PORT's current quarterly filing regime allows 60 days after quarter-end, and even the accelerated monthly regime adopted in the August 2024 amendments allows 30 days after month-end — reflecting the systemic importance of timely money market fund portfolio disclosure and the Commission's need for near-real-time monitoring of aggregate money market fund portfolio conditions.
Form N-MFP is structured in two primary parts. Part A collects fund-level information applicable to the fund as a whole, including: the fund's name, CIK number, EDGAR series identifier, and contact information; the date as of which the portfolio information is reported; the total net assets, net asset value per share, and number of outstanding shares; the fund's category under Rule 2a-7 — government, retail, or institutional (prime or tax-exempt); the weighted average maturity and weighted average life of the portfolio computed in accordance with Rule 2a-7's definitions; the daily liquid asset percentage and weekly liquid asset percentage; yield information including the seven-day yield and thirty-day yield; large shareholder information added by the 2023 amendments requiring identification of any beneficial owner of more than 5% of the fund's outstanding shares, with shareholder type classification; and information about securities sold during the reporting period, including securities sold before maturity.
Part B collects position-level portfolio data for each individual security held by the fund as of the reporting date, covering security identification, maturity date, coupon or yield, value, amortised cost, percentage of net assets, issuer category, issuer identification, liquidity classification, and all other characteristics necessary to provide a complete picture of each portfolio position.
The large shareholder disclosure added by the 2023 amendments is among Form N-MFP's most commercially sensitive and regulatory significant new reporting requirements. Institutional prime money market funds in particular are heavily concentrated in large institutional shareholder accounts — retirement plans, corporate treasury accounts, and other institutional cash management vehicles — whose redemption behaviour during periods of market stress has historically driven the run dynamics that have precipitated money market fund liquidity crises.
By requiring monthly disclosure of the identity and type of each large shareholder holding more than 5% of outstanding shares, Form N-MFP gives the Commission and FSOC the data necessary to assess concentration risk in the institutional shareholder base of individual money market funds and to monitor aggregate institutional redemption trends that may signal developing systemic stress.
The securities-sold data also added by the 2023 amendments captures information about portfolio securities that the fund sold during the reporting period — including identification of the security, the date of sale, the sale price, and whether the sale occurred before the security's stated maturity.
This transaction-level sold-securities reporting addresses a significant analytical gap in the pre-2023 Form N-MFP framework: by reporting only end-of-month holdings, the prior form could not reveal portfolio activity during the reporting period — including the forced sales of longer-maturity securities that characterised the March 2020 stress event — that might indicate developing liquidity pressure even where month-end holdings appeared stable.
Scope of Application
Rule 30b1-7 applies exclusively to registered open-end management investment companies regulated as money market funds under Rule 2a-7 — encompassing government money market funds, retail money market funds, institutional prime money market funds, and institutional tax-exempt money market funds.
The form's scope is specifically calibrated to the money market fund's distinctive characteristics: its use of amortised cost valuation and the penny-rounding convention, its Rule 2a-7-prescribed portfolio quality and maturity standards, and its systemic importance as a short-term funding market intermediary.
Non-money-market-fund open-end funds and ETFs file their monthly portfolio data on Form N-PORT under Rule 30b1-9 rather than Form N-MFP — the two forms serve parallel but distinct regulatory monitoring functions calibrated to the different portfolio characteristics and systemic risk profiles of money market funds versus other registered fund categories.
Relationship to Related Rules and Regulations
Rule 30b1-7's Form N-MFP reporting obligation is directly and operationally inseparable from Rule 2a-7's comprehensive money market fund regulatory framework.
The Rule 2a-7 portfolio quality, maturity, liquidity, and category classification requirements determine the content of nearly every Form N-MFP disclosure item — the weighted average maturity and weighted average life reported on Form N-MFP are computed in accordance with Rule 2a-7's definitions, the daily and weekly liquid asset percentages reported on Form N-MFP are the same liquidity metrics that Rule 2a-7 requires funds to maintain at or above specified minimums, and the fund category reported on Form N-MFP directly reflects the Rule 2a-7 classification that determines the fund's NAV methodology — stable $1.00 for government and retail funds, floating for institutional prime and institutional tax-exempt funds.
The large shareholder information that Form N-MFP now requires connects Rule 30b1-7's reporting framework to the broader systemic risk monitoring mandate that the Commission shares with FSOC.
The Financial Stability Oversight Council's designation authority under the Dodd-Frank Act — and its responsibility to identify and respond to systemic risks in the financial system — depends in part on the kind of granular, high-frequency data about systemically significant financial intermediaries that Form N-MFP provides for the money market fund sector.
The Commission's own systemic risk monitoring responsibilities, and its coordination with FSOC on money market fund regulatory matters, are substantially supported by the aggregate and fund-level data that Form N-MFP collects on a near-real-time monthly basis.
Rule 38a-1's compliance programme framework requires that money market fund compliance programmes specifically address the accuracy and timeliness of Form N-MFP filings — the fifth-business-day filing deadline is among the most rapid reporting obligations in the registered fund universe, and the CCO's annual report to the board must address any material compliance matters relating to Form N-MFP reporting, including any filings that were late or that contained material inaccuracies.
Amendment History and Regulatory Evolution
The June 2024 amendments to Form N-MFP — adopted as part of the July 2023 Money Market Fund Reforms rulemaking — represent the most significant expansion of Form N-MFP's reporting requirements since the form's original adoption in the 2010 post-financial crisis reforms. The 2023 amendments' additions of large shareholder disclosure and securities-sold data directly addressed the analytical gaps that the March 2020 COVID-19 stress event revealed in the Commission's money market fund monitoring capability — gaps that had prevented the Commission from identifying the concentration of large institutional shareholders whose simultaneous redemptions were driving the liquidity stress that occurred in that event before those redemptions had already substantially depleted fund liquidity.
The November 2024 technical correction to Form N-MFP's yield calculation formula — correcting the inadvertent substitution of a 7-business-day period for the intended 7-calendar-day period — is a recent example of the Commission's active monitoring of Form N-MFP data quality and its responsiveness to identified reporting errors. No changes have been made to Rule 30b1-7's operative provisions up to the present time beyond these amendments.
Enforcement Context and SEC Action Patterns
Rule 30b1-7 enforcement concentrates on failures to meet the fifth-business-day filing deadline — the most operationally stringent filing deadline in the registered fund reporting framework — and on material inaccuracies in reported portfolio data. Because Form N-MFP data is used by the Commission, FSOC, and academic researchers for systemic risk monitoring and money market fund policy analysis, material inaccuracies in portfolio composition, liquidity metrics, or yield data can distort aggregate industry-level analyses in ways that impair both regulatory monitoring and market participants' understanding of the money market fund sector's health.
The Commission's data quality monitoring programme reviews Form N-MFP filings for internal consistency — assessing whether reported WAM, WAL, and liquidity percentages are consistent with the reported position-level data — and flags funds whose reported metrics appear inconsistent with the portfolio composition they have disclosed.
Examination Relevance and Key Takeaways
Rule 30b1-7 is examined at the Series 65 level in the context of money market fund reporting obligations and the regulatory monitoring infrastructure that supports Rule 2a-7's systemic risk management framework.
The fifth-business-day filing deadline — substantially more rapid than other registered fund portfolio reporting requirements — and the Fund N-MFP's exclusive application to money market funds under Rule 2a-7 are the primary structural examination concepts.
The 2023 amendments' additions of large shareholder disclosure and securities-sold data are examined as the most recent substantive developments in the Form N-MFP reporting framework, illustrating how the Commission's portfolio monitoring infrastructure is progressively refined in response to identified gaps revealed by market stress events.
The key points to retain are these. Rule 30b1-7 requires every registered money market fund under Rule 2a-7 to file Form N-MFP no later than the fifth business day of each month, reporting portfolio holdings and operational information as of the last business day of the preceding month.
Form N-MFP collects fund-level information including NAV, net assets, fund category, weighted average maturity and life, daily and weekly liquid asset percentages, yield data, large shareholder identification for holders exceeding 5% of outstanding shares, and securities-sold data — together with position-level data for each portfolio holding.
The large shareholder and securities-sold disclosures were added by the July 2023 Money Market Fund Reforms rulemaking, effective June 11, 2024, responding to analytical gaps revealed by the March 2020 COVID-19 stress event.
A November 2024 conforming amendment corrected an erroneous yield formula in Form N-MFP instructions. Rule 30b1-7 applies exclusively to money market funds — other registered funds file monthly portfolio data on Form N-PORT under Rule 30b1-9. No changes have been made to Rule 30b1-7's operative provisions up to the present time.
