PSD2 and Open Banking – Unlocking Innovation in Financial Services

The revised Payment Services Directive (PSD2) marked a turning point for Europe's financial sector when it came into effect in 2018. Often described as the catalyst for Open Banking, PSD2 introduced rules that require banks to securely share customer account data (with permission) via application programming interfaces (APIs). By breaking the banks' monopoly on customer financial data, PSD2 opened the open banking floodgates - empowering customers to control who can access their finances and enabling a wave of fintech innovation. This new era promised more competition, better digital services, and improved consumer choice in banking.

PSD2 is a European Union directive that sets common standards for electronic payments and account data access across member states. It required every bank in the EU to implement secure open APIs so that Third-Party Providers (TPPs) - such as fintech companies or other banks - can, with customer consent, retrieve account information or initiate payments on the customer's behalf. Crucially, PSD2 established two new types of licensed TPPs:

Open Banking refers to the practice of securely sharing financial data and services through APIs to foster new apps and services. PSD2 directly enabled open banking by granting customers a legal right to share their bank account data with authorized third parties. In the past, banks were sole gatekeepers of account information; now, under PSD2, customers are in control - they can give a trusted app "read" access to their transactions or authorize a fintech service to initiate a payment without using their debit card. This access is always predicated on explicit customer consent and strong security. The forthcoming PSD3 + PSR package extends this further by mandating verification of payee, opening up the mobile payment layer, and shifting fraud liability toward PSPs and platforms; for the full breakdown see our PSD3 and PSR analysis.

By leveling the playing field, PSD2 unlocked numerous opportunities for both upstart fintech companies and established financial institutions:

Notable examples of open banking in action include:

Implementing open banking solutions requires not only creative ideas but also deep expertise in regulations and technology. Binar is a consultancy that has been at the forefront of fintech and open banking, helping banks and startups design, validate, and build compliant financial products - from vision to regulated production systems.

PSD2's rules on SCA and data handling are strict for good reason: consumers will only embrace open banking if they feel their money and privacy are safe. This is another area Binar's expertise is invaluable. We help implement bank-grade security in every solution:

PSD2 and the rise of open banking have fundamentally reshaped the European financial landscape. What began as a regulatory push for more competition and consumer choice has evolved into a vibrant ecosystem of interconnected banks and fintechs. The opportunities for innovation are vast - and they extend to any company that deals with financial transactions or data, not just banks. From enhanced digital banking services to entirely new fintech platforms, PSD2's legacy is a financial services industry that is more open, collaborative, and customer-centric than ever before.
