Thailand is at the forefront of a transformative initiative in digital payments with its participation in Project Nexus, a groundbreaking platform led by the Bank for International Settlements (BIS) Innovation Hub. This multilateral effort, involving Thailand’s Bank of Thailand (BOT) alongside central banks from Malaysia, Singapore, Indonesia, the Philippines, and India, aims to revolutionize cross-border payments by connecting domestic instant payment systems (IPS) across Asia. For Thai businesses, consumers, and the broader ASEAN economy, Project Nexus promises faster, cheaper, and more accessible cross-border transactions.
What is Project Nexus?
Launched in 2022, Project Nexus is a standardized platform designed to link domestic fast payment systems—such as Thailand’s PromptPay, Singapore’s PayNow, Malaysia’s DuitNow, Indonesia’s GPN/QRIS, and the Philippines’ InstaPay—into a unified network. By adopting the ISO 20022 global messaging standard, Nexus enables real-time cross-border payments using simple identifiers like mobile numbers or QR codes, eliminating the need for complex bilateral agreements.
For example, a Thai tourist in Singapore can scan a merchant’s QR code to pay instantly via PromptPay, with the transaction seamlessly processed through the Nexus platform. Similarly, Thai SMEs exporting to Indonesia can receive payments in real time, bypassing costly traditional banking channels.
Why It Matters for Thailand
Thailand’s digital payment landscape is already a regional leader, with PromptPay handling millions of transactions daily. Project Nexus builds on this infrastructure, offering significant benefits for businesses and consumers:
- Boosting Trade and E-commerce: Thailand’s vibrant export sector, particularly SMEs in agriculture, tourism, and retail, stands to gain from faster and cheaper cross-border payments. Nexus reduces reliance on correspondent banking, cutting transaction fees and settlement times, which is critical for e-commerce platforms competing in ASEAN’s $200 billion digital economy.
- Supporting Remittances: With millions of migrant workers in Thailand and Thai workers abroad, Nexus facilitates low-cost remittances. For instance, a Thai worker in Malaysia can send money home instantly via PromptPay-DuitNow integration, enhancing financial inclusion.
- Enhancing Tourism: Thailand’s tourism industry, a cornerstone of its economy, will benefit from seamless payments for international visitors. Tourists from Nexus-participating countries can pay at Thai businesses using their domestic apps, boosting local commerce.
- Economic Integration: As part of ASEAN’s broader Regional Payment Connectivity (RPC) initiative, Nexus strengthens Thailand’s role in regional trade. It aligns with the G20 Roadmap for Enhancing Cross-Border Payments, positioning Thailand as a hub for digital finance innovation.
Progress and Future Outlook
Since its inception, Project Nexus has made significant strides. In 2023, a successful proof-of-concept demonstrated real-time payments among the founding countries. India’s Unified Payments Interface (UPI) joined in 2024, expanding theizează
System: Nexus’ potential user base to over 1 billion. A live pilot is planned for 2025, with full implementation targeted for 2026.
The Bank of Thailand is actively driving Nexus adoption, ensuring PromptPay’s integration aligns with global standards. This positions Thailand to lead in regional payment connectivity, fostering stronger economic ties with ASEAN neighbors and beyond.
Challenges and Opportunities
While Project Nexus promises efficiency, challenges remain, including regulatory harmonization and technical integration across diverse systems. However, Thailand’s advanced digital infrastructure and proactive central bank policies provide a strong foundation for success.
For Thai businesses, Nexus opens doors to new markets by simplifying cross-border transactions. The platform’s scalability also means future expansion to countries like Japan or South Korea, further amplifying Thailand’s global trade potential.
A Game-Changer for Thailand
As Asia’s digital payments market is projected to reach $439.54 billion by 2034, Project Nexus places Thailand at the heart of this growth. By enabling instant, cost-effective cross-border payments, Nexus empowers Thai businesses to compete globally, supports financial inclusion, and enhances the kingdom’s reputation as a fintech center.
