Global API Banking Market 2026 – 2035

Reports Description

The market size of global API banking will be estimated at USD 34.8 billion in 2025 and is expected to grow to between USD 35.9 billion in 2026 and about USD 48.6 billion by 2035, with a current CAGR (compound annual growth rate) of 3.4% during the period of 2026 to 2035.

API Banking refers to using APIs (Application Programming Interfaces) to establish connectivity and enable interaction between banks and other financial institutions and entities. In other words, it is a concept that allows banks to connect, share information, and enable approved third parties to access customers’ data and payments via APIs.

It gives financial institutions the ability to make banking services easy for their clients. Through API banking, the innovation of embedded finance, open banking, and banking-as-a-service occurs. It allows companies to embed financial services in their applications and software while ensuring the necessary security, identity checks, and other requirements are met.

Significant Growth Factors

• Rising Adoption of Open Banking Regulations: The growing number of open banking regulations is a significant factor contributing to the development of the API banking market. The government and regulatory bodies around the world are compelling banks to share information about a customer’s financial needs through application programming interfaces (APIs). For example, the Revised Payment Services Directive (PSD2) in Europe, the Consumer Data Right (CDR) in Australia, and similar open finance laws in the UK, Brazil, and other countries have emerged. These regulations promote competition by enabling financial institutions and fintech companies to participate in the banking sector and offer additional services to consumers like account aggregation, real-time payments, and personal finance management. Moreover, banks are investing heavily in application programming interfaces, cloud-based solutions, and cybersecurity to satisfy the requirements of these rules, which is projected to propel the market forward.

• Expansion of Banking-as-a-Service (BaaS): The explosive growth of Banking-as-a-Service is one of the main reasons why the financial market for API banking will witness substantial growth. By providing access to core banking through API, banks enable fintechs, marketplaces, and other third parties to embed financial services such as account opening, payments, cards, lending, and compliance to acquire regulated banking functionalities. Apart from the need for embedded finance and digital banks, financial institutions are in great need of API-first platforms for a fast-track product launch, effortless third-party integration, and building an ecosystem of financial products. One prominent example that fits the theme of this article is the recently announced launch of Backbase’s AI-powered banking platform in April 2025. The innovative platform offers a powerful solution that banks can utilize to digitize and streamline their customer onboarding, payments, self-service, and sales processes by harnessing the power of agentic AI and application programming interface or API-driven banking. It is through this cloud-native and open-core banking platform that financial institutions can accelerate the launch of banking-as-a-service products while being well integrated into their legacy systems. Overall, the launch of Backbase’s AI-powered Banking Platform is a step towards composable banking using APIs, thereby fueling the global API banking market growth.

What are the Major Advances Changing the API Banking Market Today?

• Enhanced API Security And Identity Management: One of the major trends impacting the API banking market is improved API security & identity management. Modern banks are adopting advanced security technologies like OAuth, OIDC, multifactor and biometric authentication, tokenization, the zero trust security model, and artificial intelligence-driven fraud detection mechanisms to deal with the growing security threats, data privacy regulations, and the need to process a high volume of digital transactions. This security provides end-to-end encryption for sensitive data, detects and stops threats in real time, and minimizes the amount of PII (Personally Identifiable Information) data exchanged between banks and business partners. Moreover, the increasing use of open banking and embedded finance worldwide would boost the demand for improved API security and identity management internationally.

• AI-powered Banking APIs: AI-powered banking APIs have become a disruptive element in the banking industry, aiding banks and fintechs to embed intelligence in their digital financial services. Banking APIs powered by machine learning and artificial intelligence will potentially allow banks and financial institutions to build intelligent apps like fraud detection, tailored recommendations, credit scoring, smart chatbots, and predictive analytics. Furthermore, the deployment of such APIs can also help in speeding up procedures like customer onboarding, KYC/AML verification, and loan approvals, leading to lower costs and increased efficiency in operations. With the increasing demand for better digital products and next-gen financial services, AI-powered APIs can be helpful in several sectors of the banking and financial industry, such as open banking, embedded finance, and banking-as-a-service.

A number of players are choosing on-premise API banking solutions to comply with regulatory requirements, data sovereignty, and increased cybersecurity posture by hosting APIs on their existing core banking systems.

On-premise API solutions provide high levels of customization, reduced latency for key banking applications, and give enterprises control and management of security policies over their IT infrastructure. As the cloud is gaining momentum, a number of financial institutions still use on-premise API solutions to meet their business continuity, regulatory compliance, and security demands in support of hybrid IT strategies. This tendency is expected to boost the revenue growth of the on-premise segment in the global API banking market in the next years.
