Fintech has become the capillary network of our daily lives. While the past convergence of finance and technology was largely about "digitalization"—simply moving offline services online—today's transformation is closer to a "structural convergence" that is reshaping the very architecture of the industry. Fintech companies and traditional financial institutions are no longer competitors but strategic partners connecting each other's strengths, jointly shaping a movement known as "Open Innovation."
Just a few years ago, fintech was perceived within the financial sector as a "catfish" disrupting the existing order. But as the data economy has taken off in earnest, perceptions on both sides have shifted rapidly. Traditional financial firms possess capital strength, trust, and accumulated risk management capabilities. Fintech, on the other hand, excels in user-centric, agile user interfaces (UI) and user experiences (UX), along with data utilization capabilities. Both sides now recognize that combining their strengths is the real source of competitiveness. The recently spreading "BaaS (Banking as a Service)" model symbolically illustrates this change. Banks open up financial functions through application programming interfaces (APIs), and fintech firms use them to roll out innovative services. This creates a win-win structure—providing channel expansion for financial firms and infrastructure and revenue foundations for fintech players.
The key driver accelerating this cooperation is "data." The spread of MyData has shifted sovereignty over financial data from institutions to consumers, serving as a turning point that breaks down boundaries between financial firms. Fintech companies are connecting and processing scattered financial data to create high value-added services such as personalized wealth management and loan refinancing platforms. In this process, traditional financial firms are redefining their role beyond holding funds to serving as "data hubs." Ultimately, open innovation is not an option but a survival strategy. This is why major financial holding companies are operating fintech labs and expanding investment in startups.
There are also considerable challenges to resolve for successful symbiosis. The first is security and information protection. Because finance is a trust-based industry, a single incident can shake the confidence of the entire market. Banks and fintech firms differ in system architecture, security capabilities, and internal control frameworks. The spread of artificial intelligence (AI)-based services also entails new risks. Issues such as de-identification of personal information, management of training data, algorithmic bias, and the easing of network separation rules are emerging as key concerns.
The second challenge is establishing a framework for regulation and accountability. A core risk is that the party responsible in the event of an incident during data storage and utilization may become unclear. Banks bear ultimate responsibility for consumer protection, but fintech firms often handle actual service development, operation, and data processing. In API-based structures in particular, multiple operators participate simultaneously, making it difficult to delineate the scope of responsibility when incidents occur. Accordingly, there is a need to move beyond simple outsourcing arrangements and refine joint accountability frameworks and response processes among participating institutions.
As an entrepreneur who has connected data on the front lines, I am convinced. At the point where the boundary between fintech and finance disappears, a new future for Korean finance will begin. We must move beyond competing for domestic market share and advance into global markets. Just as K-content has captured the global market, "K-finance"—combining innovative fintech technology with stable financial infrastructure—also possesses sufficient global competitiveness. Banks and fintech firms are no longer competitors but reliable companions heading toward a shared future. I hope the harmony created by the stability of traditional finance and the innovation of fintech will become a new growth engine for the Korean economy.
