Abstract
Research background:
The rapid digital transformation of the banking industry is accelerating the emergence of ecosystem banking as a new strategic paradigm in global finance. Technologies such as fintech, artificial intelligence (AI), open banking, and application programming interfaces (APIs) have transformed traditional banks into interconnected digital platforms. Furthermore, growing customer demand for fast, personalised, and integrated mobile banking services, together with evolving regulatory policies, is further increasing the importance of the ecosystem banking model.
Purpose of the article:
This study aims to identify the main drivers of banking ecosystem development and assess their effects on competitiveness, operational efficiency, profitability, innovation, and customer satisfaction in the banking sector. It also analyses differences among banking ecosystem models in Europe, Asia, and North America.
Methods:
The study adopts a mixed-methods approach combining quantitative and qualitative methods. Descriptive statistics and multiple regression models are used to analyse the relationship between ecosystem integration and bank performance indicators. The empirical analysis is based on data from 25 international banks and fintech companies operating between 2018 and 2025. The variables examined include API integration, AI adoption, fintech partnerships, profitability, customer loyalty, and customer satisfaction. Strategic ecosystem management and regional differences are further explored through a comparative analysis of Ant Group, BBVA, ING, DBS Bank, Revolut, and Goldman Sachs.
Findings & Value added:
The results show that ecosystem-based banking significantly improves operational efficiency, customer satisfaction, innovation capacity, and digital revenue growth compared with traditional banking models. API integration, Banking-as-a-Service (BaaS), AI adoption, and collaboration with fintech companies are identified as key drivers of improved banking performance. The Asian market exhibits the highest level of platform integration, whereas European banks benefit from a robust open banking regulatory framework. The study extends the existing literature by examining the technological, strategic, organisational, and regulatory dimensions of integrated banking ecosystem models. The findings provide relevant implications for financial regulation, cybersecurity, and digital governance and contribute to the literature on emerging global economic trends and digital transformation.
