The Rise of Cross-Border CBDC and QR Payment Systems in Southeast Asia: Strategic Investment Opportunities in Regional Financial Infrastructure and Tourism-Driven Economic Integration

Southeast Asia is undergoing a seismic shift in its financial infrastructure, driven by the rapid adoption of cross-border Central Bank Digital Currencies (CBDCs) and QR payment systems. These innovations are not merely technological upgrades but foundational pillars of a new economic order, enabling seamless regional integration, reducing reliance on the U.S. dollar, and unlocking unprecedented opportunities for SMEs and tourism-driven growth. For investors, the region's digital payment ecosystem represents a high-conviction opportunity, with quantifiable economic impacts and a clear trajectory toward global interoperability.

Regional Collaboration and Infrastructure: The ASEAN Nexus

At the heart of this transformation is the ASEAN Regional Payment Connectivity (RPC) agenda, which aims to harmonize national QR standards and reduce cross-border transaction costs. By 2025, seven of Southeast Asia's 10 countries have implemented national QR code systems, including Singapore's SGQR, Thailand's PromptPay, Malaysia's DuitNow, and Indonesia's QRIS. These systems are now interconnected through bilateral and multilateral corridors, such as the PayNow–PromptPay linkage between Singapore and Thailand, and the Malaysia–Thailand DuitNow–PromptPay corridor.

Project Nexus, a groundbreaking initiative led by the Bank for International Settlements (BIS) and ASEAN central banks, is accelerating this integration. By creating a hub-and-spoke model where each national payment system connects to a central gateway, Nexus eliminates the need for complex bilateral agreements. With India, Malaysia, the Philippines, Singapore, and Thailand already onboard, the project is projected to facilitate near-instant cross-border payments at minimal cost, aligning with ASEAN's vision of a unified digital economy.

China's role in this ecosystem is equally pivotal. In 2024–2025, China piloted a cross-border QR linkage with Indonesia, enabling millions of Indonesian merchants to accept Alipay and UnionPay, while Cambodian and Vietnamese systems advanced interoperability with regional partners. These developments underscore a broader trend: cross-border QR payments are no longer experimental but part of a global web of interconnected systems.

Tourism-Driven Economic Integration: A Win for SMEs and Travelers

The economic impact of these systems is most visible in tourism, a sector that contributes over 10% of Southeast Asia's GDP. QR-based payments have transformed the region into a cashless tourism hub, with travelers now able to pay in local currency using their home-country apps. For example, Indonesia's QRIS system recorded 11.8 million cross-border transactions in the first half of 2025 alone, a 225% year-on-year increase. Similarly, Malaysia's DuitNow–Cambodia linkage allows automatic currency conversion, bypassing the U.S. dollar entirely.

For SMEs, the benefits are equally profound. By 2025, cross-border QR payments had generated $2.5 billion in additional revenue for SMEs in participating countries, with tourism-related spending by SMEs rising by 35%. These systems reduce transaction costs by up to 60% compared to traditional methods, enabling small businesses to compete in regional and global markets. In Bali, for instance, the adoption of QRIS has improved operational efficiency for micro, small, and medium enterprises (MSMEs), enhancing their competitiveness in the post-pandemic tourism recovery.

Strategic Investment Opportunities: Where to Allocate Capital

The convergence of policy support, technological innovation, and economic demand creates multiple investment avenues:

1. Digital Infrastructure Providers: Companies enabling API-driven interoperability, such as those developing dynamic QR code solutions, stand to benefit as Southeast Asia transitions from static to data-rich payment systems. The e-wallet market, valued at $22 billion in 2019, is projected to exceed $114 billion by 2025.

2. Cross-Border Payment Gateways: Startups and established players integrating with Project Nexus or ASEAN's RPC framework will capture a growing share of the $5.8 trillion global cross-border QR payment market by 2025.

3. Tourism-Linked SMEs: Businesses adopting QR payment systems-particularly in high-traffic destinations like Bali, Phuket, and Siem Reap-are well-positioned to capitalize on the 78% projected growth in QR payment app users by 2025.

4. Regulatory Tech (RegTech): As ASEAN finalizes the Digital Economy Framework Agreement (DEFA) in 2026, firms providing compliance solutions for cross-border transactions will see increased demand.

Regulatory Frameworks and Risks

While the region's regulatory environment is rapidly evolving, challenges remain. The ASEAN+3 Fast Payment Systems initiative and Project Nexus are addressing interoperability and standardization, but regulatory harmonization across 10 countries is complex. Additionally, the rise of stablecoins-such as Japan's yen-pegged JPYC-introduces risks related to monetary sovereignty and cybersecurity. Investors must also consider the cooling interest in retail CBDCs in Southeast Asia, with most countries pivoting to wholesale CBDCs or stablecoins. However, the focus on local currency transactions under ASEAN's RPC agenda mitigates dollarization risks, offering long-term stability for investors.

Conclusion: A Blueprint for Global Adoption

Southeast Asia's cross-border CBDC and QR payment systems are not just regional phenomena-they are blueprints for global financial integration. By reducing transaction costs, empowering SMEs, and transforming tourism into a cashless, data-driven sector, these systems are redefining economic sovereignty in the digital age. For investors, the region's digital infrastructure represents a rare combination of high-growth potential and strategic alignment with global trends. As Project Nexus and ASEAN's RPC agenda gain momentum, the window to capitalize on this transformation is narrowing.
