The adoption of open banking and open finance has become a transformative force in the global financial landscape. By enabling the secure sharing of financial data between institutions through APIs, open banking is paving the way for enhanced innovation, competition and consumer empowerment. However, the approaches to implementing open banking and open finance differ significantly across jurisdictions, with some favouring regulatory mandates while others rely on market-driven initiatives.

In this article, we analyse these two approaches, explore the implications for stakeholders and provide examples of how various markets are shaping their open banking ecosystems.

Regulatory-Led Approaches

A regulatory-led approach involves government or financial authorities creating frameworks that mandate the adoption of open banking regulations. These regulations typically define the scope, technical standards, security protocols and timelines for compliance, ensuring that all stakeholders operate under a unified system. Examples include the European Union’s Revised Payment Services Directive (PSD2), the UK’s Open Banking Initiative and recent developments in the United States.

Benefits of Regulatory-Led Approaches

1. Uniformity: Regulations ensure a consistent framework across the financial ecosystem, minimising confusion and fragmentation.
2. Consumer Protection: Clear guidelines on data privacy and security reduce risk for consumers.
3. Innovation Enablement: By standardising API protocols, regulatory approaches create a level playing field for fintechs and banks to innovate.
4. Increased Trust: Mandatory compliance builds trust among consumers and businesses alike, accelerating adoption.

Key Examples

• European Economic Area – EEA and the United Kingdom (PSD) –  PSD2 requires banks to open their customer data to third-party providers (with customer consent). This framework has given rise to an increase of newly regulated fintechs providing account aggregation and payment initiation services to the market.
• United States: The U.S. is now transitioning towards a regulatory-led approach. The Consumer Financial Protection Bureau (CFPB) has been working on implementing rules under Section 1033 of the Dodd-Frank Act, which will establish clear standards for data sharing and consumer protections, creating a more structured open banking ecosystem.
• Australia (Consumer Data Right): Australia’s approach extends beyond banking, encompassing energy and telecommunications sectors. This regulatory framework ensures that consumers can access and share their data securely across industries.

Drawbacks of Regulatory-Led Approaches

1. High Cost of Compliance: Adhering to stringent regulations required for secure data sharing can be costly.
2. Potential Stifling of Innovation: Overly rigid, prescriptive, or excessively complex regulations risk unintentionally stifling innovation, particularly for smaller organisations that may struggle to adapt.
3. Regulatory Overreach and Misalignment: Regulators may not have a full understanding of the complexities of open banking ecosystems which could result in poorly designed or overly burdensome regulations.

Market-Driven Approaches

Market-driven approaches rely on voluntary collaboration among financial institutions and fintechs. In these cases, the industry defines its own standards and protocols, often without government intervention. This approach has historically been prevalent in countries like Switzerland and China.

Benefits of Market-Driven Approaches

1. Flexibility: Industry participants can innovate without being constrained by regulatory timelines or mandates.
2. Cost Efficiency: Without regulatory compliance costs, institutions may achieve cost savings.
3. Tailored Solutions: Companies can design open banking solutions that meet specific market needs.

Drawbacks of Market-Driven Approaches

1. Fragmentation: Lack of standardised frameworks can result in incompatible systems and uneven adoption.
2. Consumer Risks: Without regulatory oversight, data privacy and security protocols may vary widely, exposing consumers to potential harm.
3. Slower Adoption: Voluntary participation may lead to inconsistent implementation across the market.

Key Examples

• Switzerland: The Swiss Bankers Association (SBA) has taken the lead in fostering a collaborative approach to open banking in the market and has worked with Swiss Fintech Innovations (SFTI) to guide both national and international stakeholder groups and voice any industry concerns. The launch of bLink, a platform to seamlessly connect data providers and data users has also been instrumental in driving market success to date.
• China: Market-driven efforts are focused on fintech giants like Ant Financial and Tencent, which dominate the landscape. However, these ecosystems often operate in silos, limiting interoperability and broader participation.
