Introduction
In today’s increasingly interconnected financial ecosystem, payment infrastructure has evolved beyond a technical backbone into a strategic national asset. It underpins economic activity, enables financial inclusion, and shapes the resilience and competitiveness of entire economies.
I hosted at Montran Africa Summit an recent expert panel featuring representatives from SWIFT and central banks and national payment infrastructure operators explored how countries and institutions can design and govern payment systems that balance sovereignty, interoperability, resilience, and innovation.
Payment Sovereignty: Control Without Isolation
At the core of the discussion was the concept of payment sovereignty—a term often associated with national control over financial infrastructure.
From a global perspective, sovereignty is less about isolation and more about resilience and autonomy. Payment systems must be designed so that no single external dependency can compromise their operation. This includes avoiding:
- Single points of failure
- Vendor lock-in
- External dependencies beyond national control
However, as emphasized during the panel, complete independence is neither feasible nor desirable. Modern payment systems rely on shared technologies, communication networks, and international standards.
The practical interpretation of sovereignty, therefore, lies in balance:
- Maintain control over critical infrastructure
- Adopt global standards for interoperability
- Ensure the ability to operate independently when necessary
Several national payment corporations across Africa or Europe, national payment corporations established by the associations of banks and the national bank, provide concrete examples of this approach. While building domestic systems tailored to the specific country needs, it relies on international standards to ensure future compatibility with global networks. Sovereignty, in this context, becomes synonymous with preparedness and flexibility, not isolation.
Infrastructure vs Innovation: Defining Roles in the Payment Stack
A key question for policymakers is determining which parts of the payment ecosystem should be treated as public infrastructure and which should be left to market competition.
The panel proposed a practical distinction:
1. Core Infrastructure (Public Interest)
This includes:
- Clearing and settlement systems
- Network connectivity
- Core switching mechanisms
These components must:
- Operate neutrally
- Provide equal access to all participants
- Ensure reliability and systemic stability
In several countries across Africa and Europe national payment corporations established by the associations of banks and the national bank fulfills this role by acting as a shared “plumbing” layer for the entire financial system, supporting banks, fintechs, and regulators alike.
2. Competitive Layer (Market-Driven)
Above the core infrastructure lies the innovation space:
- Banks
- Fintechs
- Payment service providers
Here, competition is essential. It drives:
- Product innovation
- Better customer experiences
- Lower costs
The overarching principle is clear:
Cooperate on infrastructure, compete on services.
The Growing Complexity of Risk and Resilience
As payment systems become more interconnected, the risk landscape has expanded significantly.
Panelists identified several major risk categories:
- Cybersecurity threats
- Operational concentration risks
- Geopolitical dependencies
Among these, cyber risk stands out as the most immediate and evolving threat. With real-time payments, fraud and attacks can occur at unprecedented speed, requiring institutions to:
- Detect threats instantly
- Respond rapidly
- Maintain continuous monitoring
Resilience is further complicated by:
- 24/7 system availability expectations
- Increasing inter-dependencies across platforms and regions
- The growing number of external integrations
In this environment, resilience is no longer optional—it is the defining characteristic of a viable payment system.
Cross-Border Interoperability: A Multi-Model Reality
Cross-border payments remain one of the most complex aspects of global finance. The panel emphasized that there is no single model for interoperability, but rather a coexistence of multiple approaches.
A useful distinction emerges between two primary use cases:
Business-to-Business (B2B)
- Requires high levels of standardization
- Benefits from coordinated, often regional or global, solutions
- Aligns well with initiatives such as ISO 20022 adoption
Person-to-Person (P2P)
- Often shaped by cultural, historical, and regional ties
- Requires flexible, corridor-specific solutions
- Less suited to a universal framework
From a technical standpoint, interoperability depends on several layers, including:
- Shared data foundations
- Common standards
- Business rules
- Operational orchestration
- Governance and oversight
Together, these layers enable systems with different architectures to interact seamlessly without sacrificing sovereignty.
Measuring Sustainability: Trust and Adoption
Sustainability in payment systems cannot be assessed purely through technical metrics. Instead, two key indicators emerge:
Trust
Trust is the foundation of any payment ecosystem. Without it:
- Users will not adopt digital systems
- Cash usage will persist
- Financial inclusion efforts will stall
This is especially critical in emerging markets, where large segments of the population remain un-banked.
Adoption
Adoption serves as the ultimate validation of a system’s effectiveness. Users choose payment methods based on:
- Cost
- Convenience
- Reliability
- Security
A sustainable system is one that users actively choose over alternatives.
Additionally, sustainability must also be evaluated in terms of economic impact:
- Does the system lower transaction costs?
- Does it support broader economic growth?
- Does it expand access to financial services?
The Role of Digital Public Infrastructure
Digital Public Infrastructure (DPI) is increasingly recognized as a cornerstone of future payment ecosystems.
Key components include:
- Digital identity systems
- Trusted data-sharing frameworks
- Certification authorities
Digital identity, in particular, plays a critical role in:
- Securing transactions
- Verifying participants
- Enabling cross-border payments
Looking ahead, the ability to share and validate data across borders could significantly improve payment speed, accuracy, and compliance.
Sovereignty vs Resilience: The Cloud Debate
One of the most debated topics is the use of cloud infrastructure in payment systems.
Some jurisdictions prioritize:
- Data sovereignty → keeping data within national borders
Others prioritize:
- Operational resilience → leveraging globally distributed cloud infrastructure
The panel highlighted that:
- In crisis scenarios, resilience often becomes the overriding priority
- Hybrid models (local infrastructure + regional cloud solutions) may offer a path forward
Ultimately, this is a strategic trade-off that each country must evaluate based on its regulatory, technological, and geopolitical context.
Looking Toward 2030: A Shared Vision
Despite differing perspectives, the panelists aligned on a common vision for the future.
At the national level:
- High adoption of instant payments
- Reduced reliance on cash
- Increased financial inclusion
At the global level:
- Instant cross-border payments as the norm
- Universal interoperability across payment systems
- High-quality structured data standards (e.g., ISO 20022)
- No major systemic failures
Achieving this vision will require sustained collaboration across:
- Governments
- Financial institutions
- Technology providers
Conclusion
Payment infrastructure is no longer just a technical utility—it is a strategic enabler of economic stability, innovation, and inclusion.
The path forward involves navigating complex trade-offs:
- Sovereignty vs interoperability
- Public infrastructure vs market innovation
- Security vs accessibility
Success will depend on the ability to design systems that are:
- Resilient in the face of evolving risks
- Trusted by users
- Open to innovation
- Interoperable across borders
In this balance lies the future of global payments.
