(A.) Policy and legislation

The way financial data is exchanged across institutions and companies worldwide is becoming more and more automated and complex. The financial sector is playing a crucial and systemic central role, being affected by new and emerging trends such as digitalisation and new business models. The financial services and insurance industries have seen profound technology-led changes over the past few years.

“Fintech” innovators and entrepreneurs are redefining the way we save, borrow, invest, spend and protect our money. They not only bring new financial services to the market, but also pioneer an innovative culture, introducing software, technology and business practices beyond those traditionally associated with the financial services sector. These changes again impact business operation communication flows on financial data.

Business operations benefit from standardised solutions to support and foster a more competitive and innovative European financial sector. The use of standards and technical specifications enables seamless information exchange among financial service providers, lowers barriers, underpins trust of consumers, boosts innovation and enables compliance with financial laws in a cost-effective way.

It is a challenge to find the right standardisation axis in such a rapidly transforming industry.

In parallel, regulatory efforts are trying to keep pace with the impact of digitalisation on systemic risk management, resulting in supervisory reporting obligations imposed on the entire financial sector, while stock listed companies are guided into transparency reporting obligations to leverage transparency for investors. In general, “reporting” is summarizing in various ways the recording of what happened in business operations.

Access to standardised data is essential to perform supervision of financial institutions, monitoring of systemic risk, and market oversight and ensure orderly markets, financial stability, investor protection and fair competition.

Current reporting obligations are perceived as costly and burdensome due to potentially duplicative and overlapping reporting requirements, but in reality, more due to insufficient standardisation and lack of clarity on what needs to be reported.

“Regtech” initiatives are ramping up in this domain, seeking among others digital ways to shrink the time-to-supervisor while maintaining control of business operations and understanding the details of the supervisory reporting obligations. It is imperative to standardise regulatory dictionary definitions on a European level and enable digital linking between regulation and supervisory reporting obligations.

(A.1) Policy objectives

Traditional financial institutions realize they have a lot to lose or gain from the Fintech revolution and invest huge effort and money to adapt their technology and processes to adjust to a new environment, find a place in this new ecosystem, compete with new business models and respond to new consumer needs and behaviours. Across Europe, there has been considerable uptake of new digital channels: over 58% of Western Europeans (85% for Northern Europeans) prefer to use digital over physical branches, compared to 52% of US bank customers. These trends have grabbed the attention of investors who have made massive investments, growing by 75% in 2015 to $22.3bn, five times higher than in 2013.

Fintech start-ups appear with innovative solutions challenging existing financial services business models, markets and regulation. The existing legal framework is being reviewed at EU level and the concept of regulatory experimentation frameworks (or sandboxes) explored to help address this transformation and enable innovation.

Some regulatory adjustments have already been adopted such as amendments to the Anti-Money Laundering directive and the use of electronic identification. Since July 2016, the Electronic Identification and Trust Services Regulation can give e-transactions and other e-signed documents the same legal status as those that are paper-based. The Capital Requirement Regulation CRR2 package adopted in 2016 takes technological innovations into consideration, and so is the 2017 Action Plan for Retail Financial Services.

Following several public consultations regarding financial services and the EU Parliament report on blockchain and virtual currencies, the Commission has set-up a horizontal Financial Technology Task Force to explore the impact of new financial technologies on consumers and businesses and the possible risks for financial stability. One of the work streams of the Task Force focuses on Interoperability and Standardisation.

(A.2) EC perspective and progress report

The interoperability and standards work stream of the Financial Technology Task Force was kicked off in January 2017. A consultation on FinTech took place from 23 March to 15 June 2017. The results have been published during the summer 2017.

Since 2012, the European securities and market authority (ESMA) has defined, on a yearly basis, European common enforcement priorities (ECEP) in order to promote the consistent application of European securities and markets legislation and the IFRS, and especially the provisions of the Transparency Directive. Those priorities are a key focus of the examination of issuers’ financial statements. They are made public so that listed companies and their auditors take due account of these areas when preparing and auditing IFRS financial statements.

In terms of technical standards, the EU adopted in May 2019 an RTS on the European Single Electronic Format (ESEF) for the digital format (XHTML) and structure (inline eXtensible Business Reporting Language-iXBRL ) of annual financial reports enabling both human and machine readable financial reports as required by the Transparency Directive. It should take effect from 1 January 2020 for listed companies and key financial information in all EU official languages. The extensible Business Reporting Language (XBRL) 2.1 was identified by the Commission for referencing in public procurement according to the provisions of Regulation (EU) 1025/2012 on European standardisation. In addition, the European Commission adopted in September 2020 the new Action Plan on the Capital Markets Union. The plan contains 16 legislative and non-legislative actions towards completing the CMU, among which is setting up an EU-wide platform – the European Single Access Point (ESAP). An EU-wide access to company data in digital formats will reduce information search costs for cross-border investors and will widen the investor base for companies. The ESAP will also improve the availability and accessibility of sustainability-related data.

In addition, the European Commission adopted a digital finance package on 24 September 2020 , including a digital finance strategy and legislative proposals on crypto-assets and digital resilience, for a competitive EU financial sector that gives consumers access to innovative financial products, while ensuring consumer protection and financial stability. The digital finance strategy sets out general lines on how Europe can support the digital transformation of finance in the coming years, while regulating its risks. The strategy sets out four main priorities: removing fragmentation in the Digital Single Market, adapting the EU regulatory framework to facilitate digital innovation, promoting a data-driven finance and addressing the challenges and risks with digital transformation, including enhancing the digital operational resilience of the financial system.

(B.) Requested actions

Action 1 Ensure EU level coordination on FinTech standardisation, with CEN/CENELEC, European Supervisory Authorities, Fora Consortia, Industry, and with Standards Setting Organisations (such as ISO). Also ensure proper coordination with Open Source Projects working on Blockchain.

Action 2 Develop one ‘Common Terminology’ which is uniquely defined and provides a linking method between Regulation and Supervisory Reporting following the “define once” principle. The EU ISA² Programme Core Vocabularies methodology will be used as a guideline.

Action 3 Create an external subject matter experts network on Supervisory Reporting, contributing to and validating the ‘Common Terminology’.

Action 4 Set up a governance structure to maintain the ‘Common Terminology’.

Action 5 ESMA shall continue extending the XBRL-based reporting (actually inline XBRL) of listed companies under the Transparency Directive. In this context, additional (i.e. yet uncovered) parts of the annual financial report and other regulated information of listed companies should be marked up. The taxonomy for these newly marked up parts should be developed in order to achieve standardisation at EU level.

(C.2) additional information

XBRL allows governments, regulators, institutions, private sector, etc. to build vocabularies and rules (called taxonomies) to report on different subjects, like the financial position, performance and economic viability of businesses, sustainability, gov-to-gov reporting, mortgage reporting and so on. XBRL permits the publication of structured digital financial reports, specifically matching predefined taxonomies. These may then be processed and retrieved by market participants, including analysts, supervisors, enterprise regulators, tax offices, clients, suppliers, creditors and investors.

CEN established in 2017 the CEN/BT WG 220 ‘Fintech’. The group published a report in 2018 consisting of a standardisation mapping with some recommendations for future standardisation work. The mapping provides an opportunity to identify European, international and national standards and other initiatives related to Fintech. In the follow-up to this study, CEN will look into new standards and supporting protocols for the broad adoption and use of new technologies which contribute to the establishment of industry, consumer and market confidence. Considering that the tasks of CEN/BTWG 220 are accomplished and that there is no additional work for the working group, the CEN Technical Board has decided to disband CEN/BTWG 220 ‘FinTech’.
