TL;DR: What is Open Banking? The Bottom Line

Open banking is transforming how we interact with financial data. The CFPB's final Personal Financial Data Rights rule, announced in October 2024, officially brings regulated open banking to the US starting April 2026. With over 69 countries now implementing open banking regulations and the global market projected to reach $94+ billion by 2029, this isn't just a trend—it's the future of finance.

What is Open Banking?

Open banking is a financial practice that allows consumers to securely share their banking data with authorized third-party financial service providers through Application Programming Interfaces (APIs). APIs, or application programming interfaces, enable secure and standardized access to customer accounts for various financial services, such as account aggregation, loan assessments, and financial management. Instead of banks holding exclusive access to customer data, open banking gives consumers control over who can access their financial information and for what purposes.

Think of it as giving you the keys to your own financial data. Rather than your bank account information being locked away in one institution’s vault, you can choose to share it with apps, services, and other financial providers that can help you better manage your money, get better rates, or access new financial products. This shift emphasizes consumer access and the right to their own data, empowering individuals to manage and share their financial information as they choose.

Unlike traditional banking, where financial data is siloed within individual banks and third-party access is restricted, open banking promotes data interoperability, customer empowerment, and industry innovation.

The Core Principles of Open Banking

Consumer Control: You decide who gets access to your financial data and can revoke that access at any time, ensuring your consumer data rights are protected and you can exercise those rights as needed.

Secure Data Sharing: Information is shared through secure, standardized APIs rather than risky methods like screen scraping, ensuring secure access and compliance with data protection laws.

Innovation & Competition: By opening up data access, new financial products and services can emerge to better serve consumers.

Transparency: You have clear visibility into what data is being shared and how it’s being used, as required by data protection laws.

The Current State of Open Banking in 2025

From regulatory breakthroughs to explosive global adoption, 2024 marked a turning point for open banking worldwide. Open banking initiatives, fueled by strong consumer demand and the need for innovation in the financial industry, are reshaping how financial services are delivered and accessed. Here’s where we stand today and what the numbers reveal about this financial revolution.

Open banking initiatives continue to expand globally, even as some regions face regulatory setbacks, highlighting the enduring momentum and transformative impact on the financial industry.

United States: A Regulatory Reversal

The US open banking landscape has experienced a dramatic reversal in 2025. While the CFPB finalized the Personal Financial Data Rights rule in October 2024, the Trump administration has effectively killed the regulation.

What Happened:

• February 2025: Russell Vought, Project 2025 architect and OMB Director, became acting CFPB Director
• February 8, 2025: Vought ordered CFPB staff to "cease all work" and suspended all agency operations
• May 28, 2025: CFPB officially stated the 1033 rule is "unlawful and should be set aside"
• Current Status: The agency has moved to rescind the entire open banking rule

The Dismantling of the CFPB:

• 90% staff reduction planned (from 1,755 to ~200 employees)
• $711.6 million funding frozen - Vought declared reserves "excessive"
• Website and social media deleted by Musk's DOGE team
• All supervision and enforcement halted indefinitely
• Key directors resigned in protest of the shutdown

What This Means for Open Banking:

• No federal mandate: Banks are no longer required to share data
• Market-driven approach: Industry initiatives like FDX continue voluntarily
• Regulatory uncertainty: Unclear timeline for any future federal action
• Banking wins: Industry trade groups successfully opposed the regulation

The Current Reality: Unlike Europe's regulatory mandate, the US now relies entirely on voluntary market forces and existing partnerships between banks and fintechs. This puts America significantly behind global open banking adoption.

Global Open Banking Adoption Statistics

The numbers tell a compelling story of rapid global adoption:

Europe & UK (The Pioneers)

• 14% of digitally active UK consumers used open banking in January 2024 (1 in 7 people)

How Open Banking Works: The Technical Foundation

Behind the seamless user experience lies sophisticated technology that makes secure financial data sharing possible. The open banking system is an ecosystem that enables banks, fintechs, and other third parties to exchange data securely, fostering innovation and supporting the development of new financial products. Let’s demystify the APIs, security protocols, and data standards that power the open banking ecosystem, including how API access is granted to authorized third parties to securely exchange data and enable real-time financial services.

The API Architecture

Open banking relies on Application Programming Interfaces (APIs) to enable secure data sharing. Open banking APIs are secure, standardized interfaces that allow banks, fintechs, and other financial institutions to share customer financial data with third-party providers. Open banking API standards and protocols are crucial for ensuring security, consistency, and interoperability within the open banking ecosystem. Here’s how it works:

1. Consumer Authorization: You grant permission for a third-party app to access specific financial data
2. Secure Authentication: The third-party provider uses open banking APIs to request data through the bank’s API using secure protocols
3. Data Retrieval: Your bank shares only the authorized data in a standardized format
4. Ongoing Access: The third party can access updated information as permitted
5. Control & Revocation: You can revoke access at any time

Types of Financial Data Shared

Open banking typically covers several categories of financial information:

Account Information

• Account balances and details
• Account holder information
• Transaction history
• Standing orders and direct debits

Open banking enables secure sharing of data from multiple bank accounts and financial accounts with authorized third-party providers. Through account aggregation, users can view and manage multiple accounts in one place, which streamlines account management and provides a comprehensive financial overview.

Payment Initiation

• Ability to initiate payments from your account
• Real-time payment processing
• Payment status updates

Enhanced Data (varies by region)

• Credit card information
• Investment account details
• Loan and mortgage data
• Insurance information

Security & Privacy Measures

Modern open banking implements multiple layers of security to ensure data security and maintain customer trust:

• Strong Customer Authentication (SCA): Multi-factor authentication requirements
• Transport Layer Security (TLS): Encrypted data transmission
• Tokenization: Sensitive data replaced with secure tokens
• Consent Management: Granular control over data access permissions
• Regular Audits: Ongoing security assessments and vulnerability testing

Despite these measures, open banking still faces security risks such as data breaches, hacking, and threats from third-party applications. Ongoing vigilance and robust protocols are essential to protect sensitive financial information and prevent unauthorized access.

Benefits of Open Banking: Who Wins and How

Frequently Asked Questions

Is open banking safe?

Yes, when properly implemented. Open banking uses bank-grade security measures including multi-factor authentication, encryption, and strict access controls. Regulatory frameworks like the CFPB rule include strong privacy protections. However, consumers should only share data with authorized, reputable providers.

What happened to the CFPB's open banking rule?

The rule has been rescinded by the Trump administration. In May 2025, the CFPB officially stated that the Personal Financial Data Rights rule is "unlawful and should be set aside." Acting Director Russell Vought, a Project 2025 architect, has effectively shut down the agency and halted all open banking implementation. The US now relies on voluntary market-driven initiatives rather than federal mandates.

Does this affect open banking in other countries?

No, other countries continue their open banking programs. The US regulatory reversal is specific to America and doesn't impact the 69+ countries with existing open banking regulations. However, it does create uncertainty in the global market and may slow international standardization efforts.

Will open banking still happen in the US?

Yes, but through voluntary market adoption. Industry initiatives like the Financial Data Exchange (FDX) continue to work with banks and fintechs on data sharing standards. Major companies like Plaid, Yodlee, and others still facilitate financial data connections, but without the regulatory backing that exists in other countries.

Should businesses still invest in open banking?

It depends on your market and risk tolerance. Companies operating globally should continue open banking investments for international markets. US-focused businesses should carefully evaluate voluntary partnerships with banks and monitor political developments that could restore regulatory support in future administrations.

The Bottom Line: Open Banking's Uncertain Future

Open banking represents the most significant transformation in financial services since the advent of online banking. However, the landscape has become dramatically more complex with the US regulatory reversal in 2025.

Key takeaways for 2025:

• Global Growth Continues: International markets reaching $94+ billion by 2029
• US Setback: Regulatory reversal creates uncertainty in world's largest financial market
• Two-Track Development: Regulated markets (EU, UK, Brazil) vs. voluntary markets (US)
• Political Risk: Open banking vulnerable to political and industry pressure
• Innovation Persists: Technology development continues despite regulatory uncertainty

For different stakeholders:

Consumers: Benefits vary dramatically by location - EU/UK consumers have strong regulatory protections, while US consumers depend on voluntary bank participation

Businesses: Global companies should continue open banking investments for international markets while carefully evaluating US opportunities

Financial Institutions: Must navigate a complex landscape of mandatory compliance in some markets and voluntary participation in others

The Path Forward:

The US regulatory reversal demonstrates that open banking's future isn't guaranteed. Success depends on sustained political support, industry collaboration, and demonstrated consumer value. While global momentum continues, the American setback serves as a reminder that regulatory frameworks can be fragile.

Looking ahead, open banking's evolution will likely follow regional patterns - mandatory in regulated markets, voluntary in market-driven economies. The question for stakeholders is how to navigate this fragmented landscape while building sustainable, valuable financial services.

Whether you're evaluating open banking for your business or considering its impact on your financial life, the key is understanding that this transformation is happening at different speeds in different places - and that political winds can change direction quickly.
