Universal Collaboration of CBDC adoption by all nations

CBDCs Alone Don’t Win. Why the Real Innovation Is Global Coordination
Central banks worldwide are rapidly developing Central Bank Digital Currencies (CBDCs). As of early 2025, over 130 countries are exploring or piloting CBDCs, representing nearly 98% of global GDP (Atlantic Council CBDC Tracker, 2025).

A growing field, but growing apart

Despite the momentum, these initiatives often operate in silos. Each country’s CBDC is being designed with its own technological standards, legal frameworks, and policy objectives. This fragmented approach risks recreating the very inefficiencies that CBDCs were meant to solve.
For instance, Project mBridge collaboration among several Asian central banks and the BIS, demonstrated that a shared multi-CBDC platform can significantly improve cross-border payment speed, efficiency, and settlement risk. However, the pilot highlighted the complexity of aligning policy, regulatory, and legal frameworks across jurisdictions, underscoring how even promising technical solutions require deep multilateral coordination to succeed (BIS, 2022).

History reminds us: parallel systems can isolate

Traditional finance evolved through national systems with limited coordination. Think SWIFT, ACH, SEPA, RTGS. While each served domestic priorities, the lack of cross-border alignment led to slow, costly, and opaque transactions. This historical fragmentation is well documented. According to the Bank for International Settlements, cross-border payments today remain "subject to high costs, low speed, limited access and insufficient transparency", risks CBDCs could inherit if designed in isolation (BIS, 2023a).
Many central banks are now exploring or piloting CBDCs, but most efforts are tailored to local needs and regulatory environments, often with limited international coordination. This approach, while respecting national sovereignty, risks replicating the inefficiencies and barriers that have long plagued global payments. Collaborative frameworks such as those developed by BIS and partner central banks are beginning to address these challenges, but progress remains uneven. The lesson is clear: without proactive alignment on standards and interoperability, CBDCs may reinforce the fragmentation of legacy payment systems rather than overcoming it (BIS, 2023a).

Risks of limited interoperability

The lack of interoperability among CBDCs poses significant challenges:

• Inclusion: Without seamless integration, cross-border transactions remain costly and inaccessible, undermining financial inclusion efforts.
• Security: Isolated systems may be more vulnerable to cyber threats, lacking the collaborative defence mechanisms that interconnected networks can enable.
• Resilience: A fragmented digital currency landscape could lead to systemic risks, especially during global financial crises when coordinated responses are essential.

Coordination across stakeholders is key. Structured collaboration across regulatory, policy, and technical domains is essential to avoid fragmentation and ensure that cross-border digital currency systems are inclusive, secure, and efficient (IMF, 2024; BIS, 2023a).

Security and Resilience in Practice

Ensuring CBDC systems are secure and resilient requires promoting technology diversity and interoperability within CBDC ecosystems. For example, systems should employ multiple technology solutions for critical CBDC capabilities and require each to support standard integration approaches. This means that end users’ CBDC wallets should continue to function even if the financial institution providing the wallet experiences a service outage. While this approach increases operational complexity and may entail additional costs, it significantly enhances the overall resilience and reliability of digital currency systems (BIS, 2023b).

Connectivity, not just velocity, will define success

The future of finance won’t reward the fastest pilot. It will reward the smartest connectors. Interoperability isn’t a tech feature; it’s a foundational requirement for CBDCs to deliver on their promise.
As the Atlantic Council warns, if countries develop CBDCs in isolation, the world risks creating walled gardens that stand apart from global commerce and economic trends. Creating a CBDC in a silo is unlikely to achieve the desired outcomes in the short or long term, as it will replicate the friction of the existing payments systems. Only by prioritizing interoperability and coordinated standards can CBDCs fulfil their promise of more efficient and inclusive global payments (Atlantic Council, 2024).

Strengthening multilateral coordination

In an interconnected world, the ability to transact across digital borders will shape not just economic efficiency but political alignment. While national CBDC strategies continue to diverge, several neutral and multilateral initiatives are already working to build bridges.
The BIS Innovation Hub has launched collaborative pilots, such as Project mBridge, Nexus, and Icebreaker, all of which focus on interoperability and policy-aligned technical standards (BIS, 2025). The G20 Roadmap, in partnership with the FSB, is developing frameworks to harmonise cross-border payment systems, including CBDC interoperability and regulatory coordination (Financial Stability Board, 2024). In parallel, The IMF and World Bank are providing policy guidance, technical support, and research to central banks on digital money and CBDC interoperability (IMF, 2024; World Bank, 2025). SWIFT’s own CBDC interoperability trials further illustrate the role of infrastructure providers in advancing global connectivity (SWIFT, 2024).
These efforts underscore a simple truth: technical innovation alone is not enough. Without aligned standards and policy frameworks, the global financial system risks a digital fragmentation that replicates or accelerates existing geopolitical divides. Fostering structured collaboration can facilitate the development of the underlying rails for multilateral coordination across digital currency systems.

Conclusion

The accelerating divergence in national CBDC strategies reflects more than just technological or regulatory choices. It signals deeper shifts in global financial governance. Some economies are moving quickly to reshape trade dynamics and reduce reliance on Western financial infrastructure, while others emphasize privacy, civil liberties, and institutional safeguards. From China’s rapid deployment of the e-CNY to the United States' more measured exploration, national approaches are increasingly shaped by strategic priorities. This divergence is already influencing digital payment alignments, such as bilateral arrangements across the BRICS+ bloc and cross-border pilots among G7-aligned economies (University of Technology Sydney, 2025).
In this evolving context, multilateral coordination is no longer a policy ideal but a structural necessity. Without it, the risk of entrenching digital silos that mirror and potentially accelerate existing geopolitical divides becomes real. While global consensus on CBDC design remains unlikely, multilateral forums can still broker essential layers of compatibility, including legal frameworks, technical standards, and supervisory coordination. By fostering cross-border standards, shared technical protocols, and policy alignment, such efforts can ensure that CBDCs reinforce global financial inclusion, operational resilience, and trust in an increasingly multipolar order
