Vietnam’s banking system is entering a phase where interoperability, regulatory clarity, and customer-centric services must progress together. As financial institutions modernise their infrastructure, APIs are becoming essential for enabling secure data exchange and real-time services. This shift is not just about upgrading systems—it reflects a broader transition toward open finance, where collaboration between banks and fintech firms is structured and regulated. A strong foundation in financial technology is now critical for institutions aiming to remain competitive while meeting compliance expectations in a rapidly expanding digital economy.
Why Vietnam Banking Sector Is Moving Beyond Traditional Models
Vietnamese banks are steadily moving away from branch-heavy operations toward digital-first frameworks. This transition is being shaped by customer expectations, regulatory direction, and increasing competition.
High Mobile-First Adoption & Customer Expectations
Smartphone penetration is expected to exceed 90%, while internet usage continues to rise across urban and rural regions. Customers now expect instant access to services, making traditional banking models less practical. This demand is accelerating digital transformation across financial institutions.
Non-cash payments have grown significantly, supported by systems like VietQR. Mobile transactions now dominate retail and peer-to-peer payments, reinforcing the need for scalable infrastructure.
Strategic Shift Toward New Business Models
Banks are expanding beyond conventional services by integrating finance into everyday platforms. E-commerce and mobility applications now embed financial services directly into user journeys. This shift supports the growth of a more flexible banking solution in Vietnam that connects multiple service providers.
Open banking frameworks and Bank-as-a-Service models are also gaining traction. Institutions are using APIs to collaborate with fintech firms, creating new revenue streams and improving service accessibility.
Regulatory Encouragement & Structural Support
The State Bank of Vietnam (SBV) continues to guide this transition through national programs and regulatory frameworks. Initiatives such as the fintech sandbox and digital identity systems are enabling controlled innovation while maintaining compliance.
Technological Advancement & Operational Efficiency
Cloud adoption and AI integration are helping banks improve efficiency and reduce operational costs. Institutions are increasingly relying on fintech technology to automate processes, enhance customer service, and strengthen fraud detection systems.
Increased Competitive Pressure
With hundreds of fintech firms operating in Vietnam, competition is intensifying. Banks must modernise quickly to retain market share while also preparing for regional interoperability.
Understanding Open Finance and Its Growing Relevance in Vietnam
Open finance in Vietnam is progressing beyond basic data sharing toward a structured ecosystem where customer-consented data flows securely between institutions. This model supports innovation while maintaining regulatory oversight.
Regulatory Framework
Circular 64/2024/TT-NHNN requires banks to implement standardised APIs, ensuring consistent and secure data exchange. This policy reinforces the role of financial technology in enabling compliant innovation.
Fintech & Bank Collaboration
Banks are increasingly working with fintech firms to expand their service offerings. These partnerships help bridge gaps in financial access, particularly in underserved regions.
Driving Financial Inclusion
Open finance enables tailored services such as microloans and digital savings products. These offerings are critical for improving financial access across Vietnam’s diverse population.
Key Use Cases
Applications include real-time payments, AI-based financial planning tools, and faster onboarding processes through digital identity verification.
Future Growth
Vietnam aims to establish major financial hubs in Ho Chi Minh City and Da Nang, focusing on innovation, sustainability, and cross-border financial services.
APIs as the Backbone of Open Finance Implementation
APIs form the foundation of open finance by enabling secure communication between banks and third-party providers. They support real-time data exchange while maintaining strict compliance standards.
Regulatory Framework
Under Circular 64, banks must provide API access to authorised third parties. This ensures a consistent and regulated approach to data sharing.
Phased Rollout
API implementation is being introduced in stages, starting with basic data access and progressing toward full payment initiation capabilities.
Standardisation & Security
Strict protocols such as OAuth and TLS are required to maintain secure interactions. These measures ensure that customer data remains protected at all times.
Key Use Cases
APIs support services like account aggregation, payment initiation, and digital lending. These capabilities are central to building a scalable banking solution in Vietnam.
Impact on the Fintech Ecosystem
Open API adoption is encouraging collaboration between banks and fintech firms. This integration supports embedded finance across e-commerce and mobile platforms, driven by advancements in fintech technology.
Business Impact of API-Led Banking for Financial Institutions
New Revenue Channels
APIs enable banks to offer services through third-party platforms, creating additional income streams beyond traditional lending.
Improved Customer Engagement
Personalised services powered by data insights help banks strengthen customer relationships and increase retention.
Operational Efficiency Gains
Automation reduces manual processes, lowering costs and improving service delivery timelines.
Faster Innovation Cycles
API frameworks allow institutions to test and deploy new services more quickly, supporting ongoing digital transformation initiatives.
Managing Risk, Compliance, and Governance in Open Finance
Vietnam’s open finance model is built on a regulatory-first approach that prioritises security and accountability.
Regulatory Framework
The SBV provides clear guidelines for API usage, data protection, and third-party participation. These rules ensure consistent compliance across the sector.
Data Security and Privacy
Customer consent is mandatory for data sharing. Institutions must implement strong governance frameworks to maintain trust.
Risk Management Strategy
Banks are adopting layered security models, combining API protection, AI monitoring, and digital identity verification.
Operational Governance
Compliance with international standards such as Basel II/III is essential for maintaining financial stability.
Sandbox Approach
The regulatory sandbox allows controlled testing of new solutions, helping institutions manage risk while exploring innovation.
