Regulatory Compliance for Open Banking Solutions: What Service Providers Must Know

But with innovation comes responsibility. Every participant in the ecosystem must follow strict rules and guidelines to ensure security, transparency, and trust. This is where regulatory compliance for open banking becomes essential.

This article breaks down the global regulatory landscape, core compliance principles, and the operational requirements service providers must meet for secure, compliant open banking ecosystems.

Understanding Open Banking Regulations

Open banking regulations are legal frameworks that govern how financial institutions and authorized third parties share consumer financial data. These frameworks establish the rules for safe connectivity, data security, customer consent, and interoperability.

At their foundation, open banking regulations emphasize three principles:

1. Consumer consent: Data can only be shared with explicit permission from the account holder.
2. Security: Providers must ensure all data transmissions and storage processes meet high security standards.
3. Interoperability: APIs should function reliably across platforms, ensuring consistency for users and service providers.

Foundational frameworks like PSD2 (Europe), Australia’s Consumer Data Right (CDR), and the UK’s Open Banking Standard have shaped global expectations. They show that regulatory compliance ensures both technological progress and protection of consumer rights, especially in secure data access, portability, and open banking consumer control.

Global Compliance Landscape for Open Banking

Regulatory requirements differ by region, but most share common goals: transparency, data protection, and innovation.

PSD2 – European Union

The Payment Services Directive 2 enforces:

• Secure API standards
• Strong Customer Authentication (SCA)
• Access-to-account (XS2A) rules
• Strict consent and data-sharing protocols

PSD2 is considered the global benchmark for open banking frameworks.

GDPR – Europe and global influence

GDPR applies to any organization managing personal data for EU citizens. It mandates:

• Clear user consent
• Right to erasure
• Data portability
• Transparency about how data is collected and used

CDR – Australia

The Consumer Data Right extends beyond financial services to energy, telecoms, and utilities. It gives consumers broad rights to access and share data across sectors.

North America (US & Canada)

No unified mandate exists yet. Instead, open banking advances via market-driven innovation rather than regulatory requirements. Still, momentum is pushing toward standardization, especially with payment modernization and data-sharing frameworks.

Across all regions, a global trend is emerging: a move toward harmonized standards, higher security controls, and shared responsibilities among financial ecosystem participants.

Core Principles of Open Banking Regulatory Compliance

To fully understand compliance expectations, providers must recognize the pillars of open banking regulatory compliance:

1. Transparency: Users must clearly understand what data is being shared, with whom, and for which purpose.
2. Security: Financial institutions and third parties must apply encryption, tokenization, and multi-layer authentication to protect sensitive information.
3. Consent Management: Users must explicitly authorize each data-sharing instance, with the ability to revoke permissions in real time.
4. Accountability: Both banks and third-party providers are legally responsible for secure data handling, breach reporting, and compliance documentation.

These principles establish trust and ensure stable, secure data flows across the entire ecosystem.

Key Requirements for Open Banking Service Providers

Before participating in open banking, providers must meet several regulatory and technical obligations:

API Security Standards

Providers must follow recognized frameworks such as OAuth 2.0, OpenID Connect, and FAPI (Financial-grade API). These ensure secure authentication, encryption, and authorization.

KYC/AML Compliance

Know Your Customer and Anti-Money Laundering rules require accurate identity verification and monitoring to prevent fraud.

Operational Resilience

Banks and fintechs must ensure high availability, redundancy, monitoring, and disaster recovery capabilities.

Reporting Obligations

Compliance includes incident reporting, data breach notifications, periodic audits, technical assessments, and adherence to regulator guidelines.

Some jurisdictions also require formal licensing, accreditation, or registration before participating in open banking ecosystems.

Compliance Solutions for Open Banking Providers

Meeting regulatory requirements can be complex. This is why providers adopt open banking regulatory compliance solutions to simplify and automate compliance tasks.

Key compliance technologies include:

• RegTech Platforms: Automate policy enforcement, monitoring, audit trails, and regulatory reporting.
• API Gateways: Centralize API management, control access rights, enforce security policies, and monitor performance.
• Consent Management Dashboards: Give users real-time visibility into who has access to their data, enhancing transparency and trust.
• Data Encryption and Tokenization Tools: Secure data at rest and in transit, reducing exposure to cyber threats.

Adopting these solutions reduces operational risk, ensures alignment with regulatory frameworks, and accelerates integration with partners.

Managing Third-Party and Ecosystem Compliance Risks

Open banking is a shared environment. Every participant must maintain compliance. This interdependence introduces unique risks:

• Data Misuse: Third parties mishandling or misinterpreting consumer data.
• Vendor Weaknesses: Poor security practices or legacy systems in partner organizations.
• Contractual Misalignment: Inconsistent expectations regarding monitoring, data retention, or breach response.

Effective risk management in open banking requires a coordinated approach across all ecosystem participants. 

• Service providers should conduct regular third-party audits to ensure partners meet required security and compliance standards. 
• Using standardized security frameworks helps maintain consistency and reduces vulnerabilities across different systems. 
• Implementing shared certifications strengthens trust by ensuring all parties adhere to the same rigorous benchmarks. 

Additionally, establishing clear data-handling contracts defines responsibilities, minimizes ambiguity, and ensures proper governance throughout the data lifecycle.

Together, these best practices help safeguard user information, reduce ecosystem-wide risks, and maintain long-term trust.

Common Compliance Challenges and How to Overcome Them

Here are some common problems you might encounter and how you can solve them.

Regulatory Fragmentation

Compliance becomes difficult when requirements differ across countries or regulatory zones. To solve this, you can use modular compliance tools and standardized frameworks to adapt faster.

Legacy Infrastructure

Older systems often can’t support secure API interactions, so introduce middleware, modernization strategies, and scalable API gateways.

Evolving Standards

Regulations and technical guidelines change frequently. Make sure to conduct continuous compliance monitoring and automated updates via RegTech.

Limited Resources

Small providers may struggle with cost-intensive compliance processes, so try outsourcing compliance or using shared compliance-as-a-service platforms.

The Role of Strong Customer Authentication (SCA) and Data Security

Strong Customer Authentication (SCA) is a cornerstone of secure open banking. It ensures that only legitimate users access financial data or initiate payments. Here are its pillars:

• Something the user knows (PIN, password)
• Something the user has (device, token)
• Something the user is (biometric verification)

SCA works alongside encrypted communication, tokenization, and secure session handling to ensure a safe and trusted environment for every open banking payment service.

Frameworks like FAPI (Financial-grade API) define strict guidelines for implementing these controls at scale.

Benefits of Regulatory Compliance in Open Banking

Compliance is not only a legal requirement, but a strategic advantage.

Market Credibility

Compliant organizations attract more partnerships and customer trust.

Operational Efficiency

Avoiding fines, outages, and regulatory intervention ensures long-term stability.

Partnership Readiness

Compliance simplifies integration with banks, fintechs, and other ecosystem participants.

Innovation Enablement
