Project Nexus: Pioneering the Future of Cross-Border Instant Payments
In a groundbreaking initiative, the Bank of Thailand (BOT) has joined forces with the central banks of Malaysia, the Philippines, Singapore, and India, alongside the Bank for International Settlements (BIS), to develop Project Nexus. This innovative platform aims to revolutionize cross-border transactions by seamlessly connecting various countries’ instant payment systems (IPS), with the Bank of Indonesia participating as a special observer.
As of July 2024, the collaborative effort between regional central banks and the BIS has successfully culminated in the development of a multilateral international money transfer system, marking the completion of Project Nexus’s third phase.
Transformative Benefits
Project Nexus is set to significantly enhance cross-border transactions across multiple dimensions:
- Speed: The platform will facilitate near-instantaneous cross-border payments, operating on a 24/7/365 basis.
- Cost-Effectiveness: Aligned with G20 and UN Sustainable Development Goals, Nexus aims to keep transaction costs below 3% of the transfer value.
- Accessibility: Any bank or non-bank payment service provider (PSP) eligible to join their domestic IPS will have access to Nexus for cross-border transactions.
- Transparency: Senders will benefit from clear information regarding transaction costs and payment status.

Functional Capabilities
Nexus is designed to support a wide range of account-to-account payments:
- User Categories: The platform accommodates person-to-person (P2P), business-to-business (B2B), business-to-person, and person-to-business payments.
- Payment Types: Currently, Nexus supports account-to-account push payments, with potential future expansions to include pull payments, point-of-sale merchant payments, and same-currency cross-border transfers.
- Transaction Limits: While Nexus itself does not impose an overall cap, it respects limits set by domestic IPSs and PSPs, applying the lowest applicable cap automatically.
Implementation Strategy
The project’s success hinges on three key workstreams:
- Governance Framework: Establishing robust governance, scheme, and oversight structures to ensure safe and efficient operations.
- Sustainable Business Model: Developing an attractive business and revenue model to encourage participation from key industry players.
- Technological Infrastructure: Finalizing a state-of-the-art technology architecture and operational model to support secure and smooth transactions.
Looking Ahead
As Project Nexus enters its fourth phase, the Bank of International Settlements Innovation Hub (BISIH) Singapore Centre will spearhead efforts to establish a central organization. This body will drive the integration of member countries’ payment systems and facilitate the connection of their domestic IPS through Nexus, working towards live implementation.
The Nexus project exemplifies how innovation can dramatically improve the efficiency of international payments. Thailand’s involvement signifies a crucial step towards deeper regional cooperation, with ASEAN central banks united in their ambition to expand Nexus beyond Southeast Asia. This collaborative effort underscores a shared vision of extending this service globally, potentially reshaping the landscape of international financial transactions.
As Project Nexus continues to evolve, it stands as a testament to the power of international cooperation in addressing the challenges of cross-border payments in an increasingly interconnected global economy.
