The shift toward convergence

Across the world, digital finance is evolving along different paths. While cryptocurrencies have expanded through market-led innovation, central banks have accelerated their own experiments with central bank digital currencies (CBDCs) to strengthen monetary sovereignty in a digital era.

These developments, however, have not always advanced together. In some economies, public initiatives on CBDCs have moved faster than the development of private digital assets, while in others, crypto innovation has progressed ahead of regulatory and policy frameworks. Each jurisdiction is shaping its digital future according to its own comfort with openness, control and technological readiness.

This divergence shows the world still lacks a cooperative space where public and private innovations coexist under balanced regulation. Rather than opposites, CBDCs and cryptocurrencies should function as complementary forces – one anchored in trust, the other driven by creativity.

From competition to collaboration

Rather than treating CBDCs and private cryptocurrencies as competing models, the future of digital finance may lie in drawing on the strengths of both. Each has a distinct role:

• CBDCs provide the foundation of trust and settlement finality;
• private digital assets offer flexibility and innovation; and
• legacy systems contribute reliability and scale.

Instead of competing, these systems can now interconnect. Advances in digital finance are creating trusted interoperability mechanisms that allow established banking infrastructure to communicate with newer blockchain systems. Initiatives such as the SWIFT Connector, which links CBDCs and traditional payment networks, and Visa’s Universal Payment Channel, which connects stablecoins and digital currencies across different blockchains, show that interoperability is no longer theoretical – it is already taking shape.

In this vision, traditional finance and digital assets can exchange value across platforms that once operated in isolation.

Designing the bridge

Global finance can be imagined as three cooperative layers working in harmony:

• The settlement core: Operated by central banks, this layer ensures safety and finality through CBDCs or similar sovereign digital instruments. Recent experiments, such as Project mBridge (BIS Innovation Hub) in Asia and Project Icebreaker (BIS & the central banks of Sweden, Israel and Norway), have shown how multiple CBDCs can be interconnected to settle cross-border payments in real time while preserving national monetary control.
• The innovation layer: The space where fintechs, banks and technology partners can experiment responsibly with new ideas such as tokenised deposits, programmable payments and micro-investment tools. Many regulators are now introducing regulatory sandboxes – controlled test environments that allow innovators to trial new financial technologies under regulatory supervision. These sandboxes encourage creativity while managing risk, turning financial stability into a platform for progress.
• The compliance layer: This layer keeps systems transparent and lawful through shared data standards and real-time verification. Concepts like ‘privacy by design’ (building systems that protect personal information as part of their design rather than treating privacy as an afterthought) and ‘zero-knowledge proofs’ (a method that allows one party to prove a transaction is valid without revealing personal details) illustrate how technology can balance privacy with accountability. Together, they show that innovation and regulation can reinforce each other, keeping digital finance both secure and trusted.

The aim is not to create competing systems but a modular ecosystem – a framework built from independent yet connected parts, where each layer can evolve on its own while still working seamlessly with others.

The spirit of smart regulation

Modern finance needs adaptive regulation: frameworks that evolve with technology, not resist it. Regulatory sandboxes let policymakers, banks and innovators test tokenised payment and digital-asset models in controlled settings. Oversight is shifting from slow, periodic reports to faster, tech-enabled, real-time monitoring that keeps pace with innovation.

This regulatory transformation is taking place across major jurisdictions. Recent frameworks such as Europe’s Markets in Crypto-Assets, the US’s GENIUS Act and the UK’s new crypto-asset regulatory framework share a common vision: balancing innovation with accountability. They establish clear rules and oversight mechanisms that promote transparency, consumer protection and market integrity, while still giving space for experimentation and responsible growth. By setting adaptable yet consistent standards, these initiatives illustrate how governments can preserve stability without holding back innovation in the digital-asset economy.

A cooperative vision for the G20

The G20 roadmap for enhancing cross-border payments envisions a world where money moves faster, cheaper and more transparently. Achieving that vision requires more than new technologies – it requires a shared architecture of trust that links emerging digital currencies to established financial infrastructure. In this context, the G20 has an opportunity to champion this cooperative model, blending the authority of central banks, the creativity of private innovators and the inclusiveness of global finance.

The future of money will not emerge from conflict, but from convergence, where public and private systems share a common language of trust and innovation becomes the foundation of stability.
