MMIF – Money Market & Investment Funds Return
MMIF – Money Market & Investment Funds Return
Simplifying the complex requirements
The Money Market and Investment Funds Return (MMIF) is a new mandatory reporting regime introduced to bring greater transparency, accuracy and consistency to data submitted by Irish-domiciled investment and money market funds.
Under the European Central Bank (ECB) Regulation ECB/2024/17 and the Central Bank of Ireland (CBI) framework, MMIF establishes a harmonized and detailed reporting structure for UCITS, hedge funds, and Alternative Investment Funds (AIFs) across the EU.
This initiative marks a significant step toward enhanced supervisory insight and market stability and DataTracks ensures your organisation stays fully compliant from day one.
Who Must Comply
| Effective Date | First Reporting Period | Submission Format |
| Dec-25 | For the quarter ending 31 December 2025 | XML, with granular transaction- and investor-level data |
Reporting Frequency & Deadlines
| Money Market Funds (MMFs) | Investment Funds | Frequency |
| within T+8 business days | within T+12 business days | Monthly reporting from July 2026 onwards (with limited derogation for quarterly submissions) |
What Must Be Reported
The MMIF framework requires comprehensive data reporting across fund operations, holdings, and investor activities. Each submission must include:
- A detailed breakdown of assets, liabilities, and transactions
- Investor classification, credit, and liquidity data
- A metadata return containing legal and static reference details
- An annual Anti-Money Laundering (AML) report disclosing investor counts and details of Politically Exposed Persons (PEPs)
By capturing detailed, structured data at this level, the CBI aims to improve systemic risk assessment and enable more informed policy decisions within Ireland and across the EU.
Challenges in MMIF Compliance
The new MMIF regulation introduces multiple challenges for reporting entities:
- Increased data granularity requiring precise capture and mapping
- Short turnaround times for monthly submissions (T+8/T+12)
- Complex validation requirements against CBI and ECB taxonomies
- Frequent schema updates requiring agile technology support
Without automation and validation tools, these requirements can quickly become resource-intensive and error-prone, risking regulatory non-compliance.
