Ozone API, a global leader in open banking technology, today provided OBL with an updated UK open banking model bank in its role as the model bank provider for Open Banking Limited (OBL). The company has successfully updated the model bank to support the rollout of the UK's latest open banking standards, known as Open Banking Standards v4.0. This positions Ozone API as the first provider to deliver fully compliant APIs, facilitating the transition for financial institutions and third-party providers (TPPs) operating in the UK. 

The changes, known as Open Banking Standards v4.0 (OBLv4), were announced by OBL in early July. OBLv4 introduces some mandatory updates for the UK’s CMA9 banks, with some required to be completed by as early as 31st December 2024. Additionally, ISO 20022 is set for implementation by 31st March 2025, alongside the Bank of England’s publication of mandatory updates to payment regulations. These proposed changes have been driven by several significant factors, including the deprecation of key security standards such as FAPI 1 Implementers Draft 2.  

While the UK open banking standard was initially mandated just for the CMA9 banks, it has become the de facto standard for the UK market. However, many UK banks remain on old versions of the standard.   

The OBL model bank serves as a critical testing ground for banks and financial institutions, enabling them to experiment with and refine their API implementations in a controlled and secure environment. It will serve as a vital resource for banks, fintechs, and other TPPs by providing a safe space to develop and test their APIs in alignment with the new OBLv4 standards. It is designed to help institutions comply with the regulatory changes.  

Huw Davies, CEO of Ozone API, says, “We’re delighted to confirm that we’re the first provider to launch a platform that reflects v4.0 of the Open Banking Standards for Open Banking Limited. We’re excited to work with our partners to support fast and high-quality API changes, ahead of the first legislative deadlines coming into force later this year. “Ensuring a smooth transition to the updated standards is critical for banking players who want to stay at the forefront of open banking industry changes into 2025 and beyond. We are extremely proud that our market-leading platform is ready to support our customers and partners as they transition to v4.0 

“I’m pleased that we’re able to support the entire UK financial ecosystem to start their OBLv4 journey by providing the OBL’s model bank. Our founding team were closely involved during their time working with the Open Banking Implementation Entity in the development of the UK Open Banking Standards, and we remain committed to enabling UK banks to make the most of open banking now and into the future.”  

Henk Van Hulle, CEO of Open Banking Ltd, says “Open Banking Limited is not only committed to maintaining the open banking standard, but also supporting the ecosystem by helping participants with their journey to version 4. This includes upgrading the model bank to v4 to provide as much support and coverage to participants as possible including the FCS, Standards and technical guidance.” 

Ozone API has launched a comprehensive guide and a series of educational resources to accompany the new OBLv4 standards, aimed at helping banks and FIs navigate the changes smoothly and efficiently. The guide and resources provide actionable insights and best practices for institutions of all sizes.   

Since the UK Government announced it would revisit the Data Protection and Digital Information Bill in July 2024, it is anticipated that the UK will see more regulatory changes related to open banking, smart data and the open data economy.   

Ozone API is also supporting banks in the US market this year, following the US Government announcing new open banking legislation regulations under Section 1033 of the Dodd-Frank Act.
