Open banking is transforming how financial services are delivered and consumed. APIs enabling third-party access to banking data and services have moved from regulatory mandate in some markets to competitive necessity in others. For regional and community banks, open banking presents both existential threat and differentiation opportunity.
This guide provides strategic framework for regional banks navigating open banking—addressing how to participate, what capabilities to prioritize, and how to compete effectively in an increasingly open financial ecosystem.
Understanding the Open Banking Landscape
What Open Banking Means
Open banking encompasses several related concepts:
Data sharing: Customer-permissioned access to account data by third parties. Enables aggregation, comparison, personal financial management, and lending decisioning.
Payment initiation: Third parties initiating payments from customer accounts. Enables payment experiences embedded in non-bank contexts.
Account access: Third-party connection to accounts for verification, transactions, and services.
Product integration: Banking products embedded in non-banking experiences—mortgages in real estate apps, lending in retail checkout.
Platform models: Banks as platforms hosting third-party services or as participants in others' platforms.
Market Dynamics
Open banking is advancing differently across markets:
Regulation-driven markets (EU, UK, Australia): Mandated access requirements accelerated open banking adoption. Banks must provide APIs; competition comes from how they do so.
Market-driven markets (US): Open banking emerging through market forces—screen scraping, bilateral agreements, emerging standards. Less regulatory mandate, more strategic choice.
Evolving standards: Networks like FDX (Financial Data Exchange) and emerging APIs are creating interoperability, reducing friction of bilateral agreements.
Competitive Implications
Open banking restructures competitive dynamics:
Disintermediation risk: If banking becomes commodity infrastructure, banks lose customer relationships to superior front-end experiences.
Aggregation advantage: Players who aggregate across institutions capture customer attention and data that individual banks lose.
Distribution expansion: Open banking enables new distribution—reaching customers through non-bank channels.
Data asymmetry: Third parties gain data visibility that banks historically monopolized.
Strategic Framework for Regional Banks
Regional banks face particular challenges and opportunities in open banking:
Challenges:
- Limited technology investment capacity versus large banks and fintechs
- Smaller customer base over which to amortize platform investments
- Less brand recognition outside core markets
- Fewer resources for API development and partner management
Opportunities:
- Relationship depth and trust that large banks often lack
- Agility to move faster than enterprise-scale institutions
- Community orientation that resonates with some fintech partners
- Niche expertise in specific customer segments or products
Strategic Posture Options
Defensive participation: Comply with requirements (where mandated) and market expectations; minimize investment; focus on core business. Risk: gradual disintermediation.
Selective engagement: Pursue specific open banking opportunities aligned with strategy while limiting broad platform investment. Requires strategic clarity.
Platform ambition: Invest in comprehensive API capabilities; pursue ecosystem strategy. Requires significant investment and capabilities.
Most regional banks should pursue selective engagement—strategic about where to participate rather than attempting to compete across the full open banking landscape.
Priority Use Cases
For most regional banks, focus on use cases with clear value:
Account aggregation: Enable customers to see accounts at other institutions within your experience. Shifts aggregation relationship from third parties to you.
Identity verification: APIs enabling other parties to verify customer identity and account ownership. Generates fee income; reinforces institutional relationship.
Data enrichment: Consume data from other sources to improve credit decisions, personalization, and service. Uses open banking as consumer, not just provider.
Payment initiation: Enable payments from accounts at other institutions to yours. Simplifies funding and loan payments.
Embedded lending: Extend lending products through non-bank channels via API. Expands distribution within existing credit capabilities.
Cash flow underwriting: Use transaction data to inform credit decisions for thin-file borrowers. Improves credit access and decision quality.
Building Open Banking Capabilities
API Strategy
APIs are the technical foundation of open banking:
API architecture decisions:
- Internal versus external: APIs for internal use, partner use, or public developer access
- Scope: Which data and services to expose via API
- Standards: Alignment with industry standards (FDX, Open Banking UK, etc.) versus proprietary
- Security: OAuth, tokenization, consent management, and access control
Build versus buy versus partner:
- Build: Maximum control and differentiation; requires significant investment and expertise
- Buy: Open banking platforms from vendors accelerate capability; dependency on vendor roadmap
- Partner: Banks participate in aggregate platforms; less control but lower investment
Lifecycle management:
- API versioning and deprecation policies
- Developer support and documentation
- Usage monitoring and analytics
- Performance management and SLAs
Consent and Privacy
Customer consent is foundational to open banking trust:
Consent framework:
- Clear explanation of what data will be shared and for what purpose
- Granular control over sharing scope and duration
- Easy revocation of consent
- Visibility into what's been shared with whom
Privacy considerations:
- Regulatory compliance (CCPA, GLBA, emerging state laws)
- Data minimization—share only what's needed
- Contractual protections with data recipients
- Breach response and notification
Partnership Strategy
Partnerships extend capabilities and reach:
Partner types:
- Fintechs: Complementary capabilities; reach to segments you don't serve well
- Aggregators: Distribution through platforms customers already use
- Embedded finance platforms: Enable banking in non-bank contexts
- Other banks: Consortium approaches to shared challenges
Partnership considerations:
- Strategic fit and alignment of interests
- Data rights and customer relationship clarity
- Technical integration requirements
- Commercial models and economics
- Exit provisions and protection
Risk Management
Open banking introduces new risks:
Third-party risk: Entities accessing your APIs may introduce security, reputational, or compliance risks. Due diligence and ongoing monitoring required.
Data security: APIs create attack surface. Security by design, penetration testing, monitoring, and incident response essential.
Fraud risk: Open banking can enable new fraud vectors. Transaction monitoring must evolve.
Regulatory risk: Evolving requirements may change obligations. Stay engaged with regulatory developments.
Liability clarity: When things go wrong, who's responsible? Contracts and processes must be clear.
Competitive Positioning
Differentiation Strategies
Regional banks can differentiate in open banking through:
Relationship depth: Use customer knowledge to provide contextualized experiences third parties can't match.
Service quality: When things go wrong, local presence and relationship enable resolution that remote fintechs cannot.
Community orientation: Partner with local businesses and organizations in ways that national players won't.
Specialization: Deep expertise in specific segments—agriculture, healthcare, real estate—that generalist platforms lack.
Privacy positioning: Emphasize data protection and customer control as differentiator versus data-hungry platforms.
Defending Customer Relationships
Open banking can challenge customer relationships. Defensive strategies:
Own the aggregated view: If customers see their full financial picture in your app, they don't need third-party aggregators.
Provide superior experience: Customers who love your digital experience won't seek alternatives.
Deepen relationships: More products and services increase switching costs and relationship value.
Selective data sharing: Share what's required or beneficial; don't enable competitors unnecessarily.
Expanding Through Open Banking
Open banking also enables expansion:
New distribution channels: Reach customers through partners and platforms beyond your organic reach.
New revenue streams: API access fees, data services, embedded product margins.
Adjacent markets: Serve customers at moments of financial need beyond traditional banking.
Geographic extension: Serve customers beyond branch footprint through digital channels.
Key Takeaways
-
Strategic clarity first: Before building APIs, understand where you want to win in open banking and why.
-
Selective beats comprehensive: Regional banks can't compete across the full open banking landscape. Focus on high-value use cases aligned with strategy.
-
Defend while extending: Protect existing customer relationships while using open banking to expand reach and capabilities.
-
Partnership is strategic, not tactical: Choose partners carefully; these relationships reshape competitive position.
-
Privacy as differentiator: In a world of data exploitation, trustworthy data stewardship can distinguish regional banks.
Frequently Asked Questions
Is open banking mandatory in the United States? Not currently mandated as comprehensively as in other markets, but CFPB Section 1033 rulemaking will establish data sharing requirements. Market pressure is creating de facto requirements regardless of regulation.
How much should we invest in open banking? Investment should match strategic ambition. Defensive participation might require 1-2% of technology budget; platform ambition could require 10%+ sustained over years.
Should we build APIs internally or work with vendors? Most regional banks benefit from vendor partnerships given investment requirements and expertise needs. Evaluate build/buy/partner decisions based on strategic importance and differentiation potential.
How do we choose open banking partners? Evaluate strategic fit (do they reach customers you want to serve?), technical compatibility, commercial terms, data practices, and regulatory posture. Start small and expand based on experience.
What's the role of core banking systems in open banking? Core system capability limits or enables API strategy. Modern cores with API-first architectures enable rapid open banking development; legacy cores may require middleware layers or limit possibilities. Core modernization and open banking strategies should align.
How do we manage the risk of customer disintermediation? Provide experiences valuable enough that customers prefer direct relationship. When customers use you through third parties, ensure economics and relationship visibility work for you. Some disintermediation may be acceptable if overall reach expands.
