On 7 August 2026, the European Securities and Markets Authority (ESMA) published a compliance table detailing how national competent authorities have implemented the revised guidelines on 2025 stress test scenarios under the Money Market Funds (MMF) Regulation. The table, reference ESMA34-1240783630-660, is part of ESMA's Fund Management section and accompanies the revised guidelines, which aim to strengthen the resilience of money market funds by standardising stress testing practices across the EU.
The compliance table is a key tool for transparency, showing which national authorities have confirmed their compliance with the guidelines and which have indicated reasons for non-compliance. This publication follows ESMA's earlier work on stress test scenarios, which are designed to assess the ability of MMFs to withstand adverse market conditions, such as liquidity shocks or interest rate spikes. The revised guidelines, first proposed in 2025, update the previous framework to reflect evolving market risks and regulatory expectations.
The table is addressed to national competent authorities, who are responsible for supervising MMFs in their respective jurisdictions. By publishing the compliance table, ESMA aims to ensure consistent application of the guidelines across the EU, reducing the risk of regulatory arbitrage. This is particularly important for MMFs, which play a critical role in short-term funding markets and are exposed to systemic risks, as highlighted during past financial stress events.
The revised guidelines introduce more granular and forward-looking stress test scenarios, requiring MMF managers to consider a broader range of risk factors, including climate-related risks and cyber threats. This represents a shift towards more comprehensive risk management, but also imposes additional compliance costs on fund managers, who must update their stress testing models and reporting systems. Smaller fund managers may face proportionally higher costs, potentially affecting their competitiveness.
For investors, the enhanced stress testing provides greater assurance about the resilience of MMFs, which is crucial for those using these funds for cash management. However, the increased regulatory burden could lead to higher fees or reduced product offerings, particularly for smaller funds. National authorities, meanwhile, benefit from clearer guidance and improved comparability of stress test results, but must allocate resources to monitor compliance and enforce the guidelines.
The compliance table is a formal document that records the status of implementation, but it does not itself impose new obligations. It is part of ESMA's ongoing efforts to harmonise supervisory practices and follows the European Commission's broader agenda to strengthen the resilience of the EU's capital markets. ESMA has not indicated any immediate follow-up, but the table will be updated as national authorities confirm their compliance or revise their positions.
