Open banking was introduced with the promise of transforming financial services by allowing banks, fintech companies, and third-party providers to securely share financial data through APIs. The model was expected to accelerate innovation, increase competition, and give consumers greater control over their financial information. Several years after major regulatory frameworks such as PSD2 in Europe and open banking initiatives in other regions, progress has been uneven. While the technology foundations are in place, the broader transformation of banking ecosystems has been slower than many industry observers initially predicted.
1. Many Banks Treated Open Banking as a Compliance Exercise
One of the biggest barriers to open banking success has been how banks initially approached the concept. In many markets, open banking was driven by regulation rather than by commercial strategy.
As a result, a large number of banks implemented APIs primarily to meet compliance requirements rather than to develop new digital business models. These implementations often focused on basic data-sharing capabilities with limited developer support or innovation.
Without strong commercial incentives, open banking platforms struggled to evolve beyond the minimum requirements set by regulators.
2. Weak API Quality and Fragmented Standards
While open banking frameworks require banks to provide APIs, the quality and consistency of those APIs has varied widely.
In practice, fintech developers frequently encounter challenges such as inconsistent data formats, unstable connections, and varying authentication processes across institutions. This fragmentation increases integration complexity and slows the development of new financial services.
In regions where strong technical standards and centralised infrastructure exist, open banking ecosystems have progressed faster. Where standards remain fragmented, adoption has been slower.
3. Limited Monetisation Models for Banks
For many financial institutions, the business case for open banking remains unclear.
Providing APIs requires investment in infrastructure, security, and developer platforms. However, many regulatory frameworks require banks to provide certain data access services free of charge, which limits direct revenue opportunities.
As a result, some banks have been hesitant to fully embrace open banking as a platform strategy. Without clear monetisation models, open banking initiatives can struggle to gain long-term executive support.
4. Customer Awareness Remains Low
Despite years of regulatory progress, many consumers remain unfamiliar with the concept of open banking and how it benefits them.
Data sharing between banks and third-party applications often requires explicit customer consent. However, customers may hesitate to grant access to financial data if they do not fully understand how the ecosystem works.
This lack of awareness has slowed adoption for many fintech services that rely on open banking infrastructure.
5. Banks Still Compete With Fintechs Instead of Collaborating
Open banking was originally designed to encourage collaboration between banks and fintech companies. In reality, relationships between the two sectors have sometimes been more competitive than cooperative.
Some banks view fintech companies primarily as competitors rather than partners. This dynamic can limit the development of joint services that leverage the strengths of both institutions.
Where banks and fintech firms have successfully collaborated, however, open banking has delivered tangible results, including improved financial management tools, embedded finance services, and new payment experiences.
What this means for the industry
- Open banking infrastructure is largely in place, but commercial models are still evolving.
- Banks that treat open banking as a strategic platform rather than a regulatory requirement will be better positioned to capture new revenue streams.
- Strong API standards and developer ecosystems are critical for accelerating fintech innovation.
- Consumer education will play an important role in driving wider adoption of open banking services.
- Collaboration between banks and fintech companies will determine whether open banking reaches its full potential.
