The SRB Mandate and Banks Operating in France: Simplifying MREL and TLAC Reporting with IRIS iDEAL®

Regulatory pressure on eurozone banks has never been more intense. With evolving mandates from the Single Resolution Board (SRB) and increasing scrutiny by the European Central Bank (ECB), financial institutions are expected to deliver liability data that is not only timely and accurate but also highly granular and audit-ready. 

At the heart of this oversight are the MREL (Minimum Requirement for own funds and Eligible Liabilities) and TLAC (Total Loss Absorbing Capacity) frameworks—regulatory safeguards designed to ensure that banks can absorb losses and support orderly resolution without taxpayer bailouts. 

For French banks, meeting these obligations involves more than just form-filling. It demands streamlined data sourcing, validation against dynamic templates, and full regulatory traceability—across entities, systems, and jurisdictions. That’s where IRIS iDEAL® steps in: a future-ready reporting platform built to simplify SRB compliance through automation, accuracy, and end-to-end control. 

The Single Resolution Board (SRB) is the central resolution authority for the Banking Union. Established in 2015 as a part of the EU’s post-crisis reforms, the SRB works in conjunction with National Resolution Authorities (NRAs), the European Central Bank (ECB), and the European Banking Authority (EBA) to ensure that failing banks can be resolved without triggering a financial crisis or requiring public funds. 

The SRB’s primary objectives include: 

• Developing resolution plans for significant and cross-border banks, 

• Setting institution-specific MREL requirements, 

• Ensuring that banks are resolvable under various scenarios, 

• Coordinating resolution strategies during crises. 

The SRB’s approach is risk-based, proportionate, and focused on resolvability. Central to this is the regular collection of liability-related data from banks—structured and standardized under stringent templates. 

MREL refers to the Minimum Requirement for own funds and Eligible Liabilities. Introduced under the Bank Recovery and Resolution Directive (BRRD), MREL aims to ensure that banks have sufficient loss-absorbing capacity in case of failure, thus avoiding taxpayer-funded bailouts. 

Key attributes of MREL: 

• Set on a bank-specific basis by resolution authorities, 

• Comprises both regulatory capital and eligible liabilities, 

• Tailored according to the resolution strategy (single-point-of-entry vs. multiple-point-of-entry).

TLAC stands for Total Loss Absorbing Capacity and is a global standard issued by the Financial Stability Board (FSB). While MREL applies EU-wide, TLAC applies mainly to Globally Systemically Important Banks (G-SIBs) and is embedded within MREL for EU implementation. 

TLAC requirements: 

• Ensure G-SIBs maintain enough capital and liabilities to absorb losses during resolution, 

• Must be met with specific instruments such as subordinated debt or equity, 

• Are monitored for compliance under both EU and global frameworks. 

French banks are required to report structured liability data to the SRB using two main templates: 

• Liability Data Report (LDR) – captures granular data on liabilities, capital instruments, and their legal features. 

• Additional Liability Data Report (ALDR) – provides complementary and contextual information. 

1. High Data Granularity: Each report may contain thousands of data points, including maturity dates, contractual terms, governing laws, and subordination rankings. 
2. Data Sourcing Across Functions: Information needs to be gathered from treasury, finance, risk, legal, and operations. 
3. Template and Rule Changes: The SRB updates templates regularly, requiring banks to adapt systems quickly. 
4. Validation and Audit Trails: Strict technical and business rule validations must be passed before submission. 
5. Tight Timelines: Submission windows are short and often overlap with other regulatory obligations (e.g., FINREP, COREP, SURFI). 

If mismanaged, these reporting requirements can result in non-compliance, penalties, or a poor supervisory rating. 

To make regulatory reporting more efficient and standardized, the SRB and ECB have initiated several reforms: 

• Adoption of the Data Point Model (DPM): The LDR and ALDR templates now follow a DPM and are submitted in XBRL—a structured, machine-readable format that facilitates automated validation. 

• Convergence with EBA/ECB Reporting: Efforts are being made to harmonize MREL/TLAC data with EBA Pillar 3, FINREP, and COREP disclosures. 

• Emphasis on Data Quality: The SRB has launched feedback loops and benchmarking exercises to assess and improve the quality of submissions. 

• Supervisory Technology Use: The ECB and SRB are deploying SupTech tools to analyze submissions, identify inconsistencies, and cross-reference exposures in near real-time. 

These developments underscore the urgency for banks to move away from spreadsheets and toward agile RegTech platforms. 

Regulatory authorities, including the SRB and European Central Bank, emphasize data quality as the cornerstone of effective supervision and resolution planning. High-quality data enhances: 

• Credibility of resolution strategies, 

• Accuracy of risk assessments, 

• Timeliness in resolution execution, 

• Cross-border coordination during a financial crisis. 

Poor data quality can result in misreporting, compliance risks, and even supervisory sanctions. Therefore, banks must invest in data integrity measures—validation, reconciliation, audit trails, and exception management—to meet SRB and ECB standards.

• Faster submission cycles by removing bottlenecks in data preparation, 

• Improved data accuracy and regulator trust, 

• Lower compliance costs through reusability of data and reporting components. 

By adopting a platform purpose-built for structured regulatory reporting, French banks can transform reporting from a compliance headache into a strategic advantage. 

The European Central Bank is continuously pushing for supervisory convergence, transparency, and digital transformation in the Banking Union. It envisions a future where: 

• Reporting frameworks are interoperable across national and EU authorities, 

• Supervised banks adopt machine-readable formats (XBRL, SDMX), 

• There is real-time supervisory access to critical metrics. 

Platforms like IRIS iDEAL® are not just tools—they are enablers of this digital transformation. As MREL and TLAC frameworks evolve, and as the ECB tightens its expectations around data quality, banks will increasingly rely on technology that bridges compliance with innovation. 

The SRB mandate—safeguarding financial stability through structured resolution planning—is a critical layer in Europe’s supervisory architecture. For banks, meeting MREL and TLAC reporting requirements is no longer about just ticking boxes; it is about building credibility and resilience in the eyes of the European Central Bank and other regulatory bodies. 

By leveraging IRIS iDEAL®, French and European banks can meet SRB requirements with accuracy, efficiency, and confidence—whether through on-premise control or cloud-powered agility.
