Summary of "BANKING SUPERVISORS AND XBRL" by Jose María Roldán

Introduction

Jose María Roldán, Director General of Regulation at Banco de España and Chair of XBRL España and CEBS, presented at the 1st European XBRL Conference for Financial Services in London on 29 June 2005. He spoke in three capacities: as a representative of Banco de España, XBRL España, and CEBS. The presentation focused on the role of XBRL in improving financial information flows and its implications for banking supervision.

The Importance of XBRL

XBRL is not merely a technical IT issue, but a tool that enhances market efficiency by improving the flow of financial information. It is particularly relevant to banking supervision, both at the national and international levels. The benefits of XBRL include:

• Flexibility: Enables adaptable reporting structures
• Integrity: Ensures accurate and consistent data
• Speed: Facilitates faster data processing and exchange

These features make XBRL a valuable asset for both the generators and users of financial information, ultimately promoting greater efficiency across the financial system.

The Spanish Perspective

Spain became an XBRL jurisdiction in 2004, and the XBRL España Association, chaired by Banco de España, plays a central role in promoting the adoption of XBRL. The association:

• Has grown from 11 founding members to 36 current members
• Collaborates between regulators and public sector bodies
• Develops 7 domestic taxonomies and contributes to the CEBS Common Reporting taxonomy

The aim of XBRL España is to foster the introduction, adoption, and development of XBRL language at both national and international levels to unify financial and business reporting standards.

The International Perspective

The banking sector is increasingly international, and XBRL offers a common language for financial information. This can:

• Facilitate supervisory cooperation
• Promote a level playing field
• Support the EU single market by enabling a unified set of accounting and prudential rules

CEBS and Common EU Reporting

CEBS (Committee of European Banking Supervisors) is a high-level committee representing EU banking supervisory authorities and central banks. Its tasks include:

• Advising the European Commission on banking policy
• Issuing guidelines and standards for consistent implementation of EU legislation
• Promoting supervisory cooperation and information exchange

CEBS has launched two major initiatives for common reporting:

1. COREP (Common Reporting of the Solvency Ratio): Public consultation ended on 30 April 2005
2. FINREP (Common Reporting for Financial Data): Public consultation is ongoing

These initiatives aim to align reporting requirements under Basel II and IAS, with a focus on creating a common framework while balancing simplicity and harmonization.

Benefits of Common Reporting

The adoption of XBRL in common reporting can lead to several benefits:

• Level playing field: Ensures fair competition across EU institutions
• Reduced administrative burden: Especially for cross-border groups and small banks
• Facilitates financial market integration: Removes barriers to data exchange
• Easier information exchange between supervisors
• Increased cost-effectiveness: Of supervisory activities
• More flexible framework: That can adapt to different national requirements and evolve over time

Impact of XBRL

Currently, financial reporting involves multiple data streams, different standards, and manual processes. With XBRL, this will shift to:

• A common framework
• A single format
• Automated data collection

This transition is expected to streamline the reporting process and enhance the quality and timeliness of financial data.

A Word of Caution

While the convergence of reporting standards across the EU is desirable, it comes with challenges:

• Legal issues related to differing national regulations
• Flexibility in adapting to various requirements
• Time needed for implementation

CEBS' approach to XBRL-based reporting aims to mitigate these issues through coordinated efforts and the development of a common taxonomy.

How XBRL Can Enhance Common EU Reporting

XBRL offers several advantages for common EU reporting:

1. Single IT standard: Allows banks to meet reporting requirements across the EU with one system
2. Reduces costs: Both for banks and supervisors through economies of scale
3. Flexibility: Enables customization of data for different regulatory needs
4. Consistent data transmission: Supports the common definitions in EU reporting, promoting transparency and integration

The Risks of Progress

Rapid development of XBRL in various regions may lead to inconsistent results. However, this does not mean slowing down progress. Instead, good coordination is essential. Bodies like XBRL España and CEBS play a crucial role in ensuring alignment and consistency.

The Prospects of Success

Despite the challenges, the prospects for XBRL adoption in banking are strong. Even in a worst-case scenario where XBRL is implemented only in Spain for banks, the benefits would be substantial. Future steps include:

• Full adoption by all regulators in Spain
• Implementation by all EU banking regulators
• Expansion to global reporting under Basel II and IFRS

XBRL makes sense even in the worst-case scenario, as it provides a robust and scalable solution for financial reporting.

Conclusion

Jose María Roldán emphasized the transformative potential of XBRL in enhancing the efficiency, consistency, and transparency of financial reporting and supervision. The role of CEBS and XBRL España is critical in driving this change and ensuring its success across the EU and globally.
