In a move that signals a significant shift in the landscape of digital finance, iFAST Global Bank, the rapidly expanding UK-licensed digital bank, has entered into a strategic partnership with Ozone API, the global leader in standards-based Open Banking technology. This collaboration is designed to ensure that iFAST Global Bank not only maintains seamless compliance with the Second Payment Services Directive (PSD2) but also secures a competitive edge by migrating to the latest UK Open Banking Standard, version 4.0. By adopting this advanced framework, iFAST Global Bank aims to future-proof its multi-currency current account propositions for both individual and business clients, positioning itself at the vanguard of the next generation of financial services.
The partnership represents a critical milestone for iFAST Global Bank as it seeks to fulfill its vision of creating a globally connected digital banking experience. By leveraging Ozone API’s industry-leading technology, the bank will offer secure, standards-compliant Open Banking APIs that facilitate frictionless cross-border transactions and account management. This development comes at a time when the UK banking sector is facing increasing pressure to modernize its digital infrastructure to meet evolving regulatory requirements and rising consumer expectations for transparency and speed.
The Strategic Migration to Open Banking Standard v4.0
While a substantial portion of the UK’s financial institutions continue to operate on legacy versions of the Open Banking Standard, iFAST Global Bank has distinguished itself as an early adopter of version 4.0 (OBL v4.0). The bank has committed to a comprehensive transition to this new standard by January 2026. This move is not merely a regulatory checkbox but a strategic decision to embrace a more robust, scalable, and secure technical architecture.
The evolution from version 3.x to version 4.0 of the UK Open Banking Standard represents the most significant update to the framework in years. Version 4.0 introduces several critical enhancements designed to improve the reliability and performance of the Open Banking ecosystem. Key improvements include better alignment with international messaging standards such as ISO 20022, enhanced security protocols to combat sophisticated fraud, and more streamlined data-sharing mechanisms. For iFAST Global Bank, this transition ensures that its APIs remain interoperable with a wider range of Third-Party Providers (TPPs), thereby expanding the ecosystem of services available to its customers.
Financial Performance and Market Momentum
The announcement of this partnership follows a period of exceptional growth for iFAST Global Bank. Since its acquisition by the Singapore-listed fintech powerhouse iFAST Corporation in early 2022, the bank has undergone a rapid transformation. In a notable financial milestone, iFAST Global Bank achieved profitability in the fourth quarter of 2024, less than three years after joining the iFAST Group. This achievement is particularly significant given the high customer acquisition costs and capital requirements typically associated with scaling a digital bank in the competitive UK market.
Central to this success has been the bank’s Digital Personal Banking division, which has resonated with a global audience seeking stable, multi-currency banking solutions. As of late 2024, the bank reported holding over $1 billion (SGD) in customer deposits. This influx of capital reflects growing market confidence in the bank’s ability to provide secure, innovative, and transparent financial products. The integration of Ozone API’s technology is expected to further catalyze this growth by making the bank’s services more accessible to fintech integrators and corporate partners through standardized API gateways.
A History of Collaboration and Technical Excellence
The relationship between iFAST Global Bank and Ozone API is not new; the two entities have been collaborating since March 2023. The initial phase of their partnership focused on establishing a baseline for PSD2 compliance and implementing the UK Open Banking Standard version 3.1.11. However, as the regulatory environment in the UK shifted toward more stringent requirements for resilience and consumer protection, both parties recognized the need for an upgrade.
The transition to version 4.0 was completed in early 2026, marking the culmination of a multi-year technical roadmap. Ozone API’s platform provided the necessary "out-of-the-box" compliance and the flexibility to adapt to the unique multi-currency requirements of iFAST Global Bank’s portfolio. By using a standards-based approach, Ozone API allows financial institutions to avoid the pitfalls of bespoke, proprietary builds which are often difficult to maintain and update as regulations evolve.

Leadership Perspectives on Innovation and Governance
Inayat Kashif, Chief Executive Officer of iFAST Global Bank, emphasized that the partnership is a cornerstone of the bank’s broader digital strategy. According to Kashif, the adoption of the 4.0 standards is instrumental in strengthening the foundations of their multi-currency accounts. He noted that the move allows the bank to offer a secure and seamlessly connected experience across borders while maintaining rigorous governance and regulatory alignment.
Kashif also highlighted the importance of the UK’s Consumer Duty regulations, which require firms to act to deliver good outcomes for retail customers. "Importantly, it enables us to deliver clearer, more transparent products that provide fair value and better outcomes in line with our Consumer Duty commitments, as we continue to grow responsibly and innovate with confidence," Kashif stated. This focus on "fair value" is a direct response to the Financial Conduct Authority’s (FCA) mandate for banks to prove that their products and services are designed with the customer’s best interests in mind.
Huw Davies, co-founder and CEO of Ozone API, praised iFAST Global Bank’s proactive approach to technology. Davies remarked that iFAST is a prime example of a modern digital bank that views Open Banking as a growth strategy rather than a regulatory burden. He pointed out that the bank’s ability to amass significant deposits in a short timeframe is a testament to its digital-first philosophy. Davies reiterated Ozone API’s commitment to providing a high-quality foundation that ensures continuous compliance while enabling banks to embrace the commercial potential of Open Finance.
Analysis: The Broader Implications for the UK Fintech Ecosystem
The move by iFAST Global Bank to adopt OBL v4.0 carries broader implications for the UK financial sector. First, it sets a benchmark for other mid-tier and digital banks. As the Joint Regulatory Oversight Committee (JROC) continues to refine the future of Open Banking in the UK, institutions that lag behind on technical standards may find themselves at a disadvantage, both in terms of regulatory scrutiny and their ability to partner with innovative TPPs.
Secondly, the focus on multi-currency capabilities addresses a specific gap in the market. While many UK banks offer basic Open Banking connectivity, few have optimized these APIs for multi-currency environments. iFAST Global Bank’s focus on this niche makes it an attractive partner for international businesses and "digital nomads" who require seamless movement of funds across different jurisdictions without the friction of traditional wire transfers.
Furthermore, the transition to v4.0 is a precursor to the wider "Open Finance" movement. Open Finance seeks to extend the principles of Open Banking—data sharing and third-party access—to a broader range of financial products, including savings, investments, and pensions. By mastering the most advanced Open Banking standards today, iFAST Global Bank is laying the groundwork to integrate its wealth management and investment services into a unified API ecosystem in the future.

Conclusion and Future Outlook
The strategic alliance between Ozone API and iFAST Global Bank illustrates the maturing of the Open Banking sector. It is no longer enough for banks to simply be "compliant"; they must be agile. The migration to version 4.0 provides iFAST Global Bank with the technical resilience needed to navigate a volatile global economy while offering customers the transparency and security they demand.
As the January 2026 deadline for many industry-wide updates approaches, the success of iFAST Global Bank will likely serve as a case study for how digital banks can leverage standardized APIs to drive commercial growth and international expansion.
