MARKET GROWTH FACTORS

1) Regulatory frameworks and policy mandates

Regulatory initiatives like Europe’s PSD2 and various national open banking frameworks are key drivers of growth. By mandating that banks share customer-authorized data through secure APIs, these regulations have pushed traditional banks to open up their ecosystems, allowing third-party providers to deliver unique services. This regulatory push for interoperability lowers the barriers for fintech companies, sparks competition, and encourages established banks to collaborate with or develop fintech capabilities. Additionally, this regulatory environment builds consumer trust through standardized consent and security measures, which are essential for widespread adoption. As more regions roll out formal open banking regulations, global market growth is not just fueled by direct usage—like payments, aggregation, and account-to-account services—but also by the innovative value-added services that emerge, such as personalized lending, wealth management, and embedded finance. The report emphasizes Europe’s pioneering role under PSD2 as a model for other regions to follow, creating a growing demand for API platforms, compliance tools, and ecosystems for third-party developers.

2) Technological advancements — APIs, AI and blockchain

Recent advancements in API technology, along with standardized data formats and secure authentication methods, have paved the way for fast and seamless data exchange. Today’s API frameworks empower banks and fintech companies to quickly and securely create modular services—think instant payments, account aggregation, and handy plug-in tools. At the same time, AI and machine learning are taking personalization to the next level (like credit scoring, robo-advice, and fraud detection) by utilizing richer datasets that open banking provides. We’re also seeing blockchain and distributed ledger technologies being tested for secure and auditable data sharing in specific applications. This tech stack simplifies integration and cuts operational costs for banks, while allowing fintechs to deliver unique user experiences. There’s a growing investment in API marketplaces, developer portals, SDKs, and middleware platforms, highlighting the demand for solid development tools and monitoring solutions. These technological strides are speeding up product launches, boosting consumer satisfaction with tailored offerings, and fueling ecosystem growth—ultimately driving a strong projected CAGR for the market.

3) Rising consumer demand for personalization and digital experiences

Consumers are increasingly looking for banking services that offer the same level of personalization and convenience they enjoy with other digital platforms. Open banking paves the way for a stream of authorized data that both fintech companies and banks can use to create customized budgeting tools, personalized credit and investment options, and smooth payment experiences. The growing demand for improved user experiences, real-time insights, and a unified view of finances is driving adoption among both retail and small to medium-sized enterprises. Additionally, businesses are tapping into open banking to speed up onboarding, credit evaluations, and account verifications, which boosts their operational efficiency. The rise of mobile banking apps and app marketplaces—identified in the report as a key distribution channel—shows that consumers prefer third-party applications that utilize open APIs to offer specialized, value-added features. This focus on user needs is prompting established banks to invest in API ecosystems and collaborate with fintechs, creating a positive cycle of product innovation, increased engagement, and ongoing revenue streams for both banks and platform providers.
