Introduction

Cross-border digital payments sit at the heart of Asia’s digital trade expansion and are a prerequisite for firms to participate in regional and global commerce. Firms cannot sell goods or services if they cannot be paid, making payment services a critical component of the online services ecosystem. For micro, small and medium-sized enterprises (MSMEs), cross-border e-payments are especially important in a post-Covid environment, where digital channels have become central to resilience and growth.

Despite rapid innovation in domestic payments driven by e-wallets, QR codes and mobile platforms, cross-border e-payments in Asia remain slow, costly, opaque, and difficult to manage. A lack of access, competition, and interoperability across jurisdictions continues to constrain MSMEs, particularly in a region marked by wide variation in technological maturity, regulatory frameworks, standards, and digital infrastructure. Without a supportive regional ecosystem for payments, firms of all sizes face higher costs and missed opportunities in neighboring markets.

Cross-border e-payments in Asia

Cross-border digital payment solutions have expanded quickly alongside rising cross-border e-commerce and demand for international financial services. Asia hosts the world’s fastest-growing e-commerce market, projected to expand by 25%-35 % annually over the next five to ten years. The Asia-Pacific region overtook Europe and North America to become the global leader in non-cash transaction volumes, reaching US$234.6 billion in 2019 and projected to hit US$493.2 billion by 2023. Annual revenue from the region’s digital payments sector is expected to exceed US$1 trillion.

China, India, and Southeast Asian economies are driving this growth, propelled by smartphone adoption, booming e-commerce, digital wallets, and mobile payment innovations. Within the Association of Southeast Asian Nations (ASEAN) alone, digital payment transaction values reached US$73 billion in 2018 and were expected to double by 2023. Importantly, MSME usage of cross-border payments has been growing at two to three times the rate of large corporates, underscoring the sector’s importance for inclusive growth.

E-payments: not just for big firms

Digital payments are not limited to large platforms or multinational firms. Governments increasingly see e-payments as tools to boost efficiency, combat the grey economy, and improve transparency, even among the smallest businesses. Initiatives such as Singapore’s “Hawkers Go Digital” program, aimed at bringing 18,000 small food and beverage vendors online, illustrate how digital payments can be mainstreamed at the micro level.

For MSMEs, digitalization lowers the cost of internationalization and allows even the smallest firms to operate as “micro-multinationals.” However, while digital platforms have expanded opportunities, an inability to easily manage multiple payment systems across borders remains an often-overlooked constraint on MSME participation in regional trade.

Managing cross-border retail payments is inherently complex. Transactions typically involve multiple intermediaries, currencies, time zones, and regulatory regimes. Even transactions that appear domestic can involve cross-border data flows, such as offshore fraud checks. These layers of complexity increase costs, delay settlement, and introduce uncertainty for businesses.

Challenges in the management of cross-border retail payments

Correspondent banking remains a central pillar of cross-border payments in Asia, especially for MSMEs. While widely used, the model is opaque and fee-heavy. Interviewed MSMEs reported transaction fees as high as US$45-US$70 per payment, often borne entirely by the merchant. A lack of transparency makes it difficult to predict final costs, and several firms reported receiving less than the invoiced amount due to hidden intermediary fees.

Foreign exchange (FX) costs compound these challenges. Many MSMEs operate in currencies not commonly used for international transfers, exposing them to volatile exchange rates and high conversion fees. Surveys consistently rank FX risk among the top barriers to cross-border e-payments, with rate discrepancies eroding already thin MSME margins.

Time is another major constraint. Opening bank accounts with cross-border functionality can be slow and administratively burdensome, sometimes requiring hours of paperwork and extensive personal documentation. Settlement times for bank transfers can stretch up to five days, disrupting cash flow and complicating operations, particularly when transactions span multiple time zones.

Trust and familiarity also shape payment choices. Many customers resist alternative methods they perceive as risky or inconvenient, reinforcing reliance on inefficient legacy systems even when faster digital solutions exist.

New technologies, including e-wallets, fintech platforms and blockchain-based solutions, offer the potential to lower costs and speed up transactions, especially for MSMEs. Yet most innovation remains concentrated in domestic markets. Cross-border deployment lags due to regulatory fragmentation, limited interoperability, and uncertainty around compliance requirements.

Regulatory barriers play a decisive role in shaping payment efficiency. Restrictions on cross-border data flows, data localization requirements and limits on market access raise costs and deter entry by innovative payment service providers. Requirements to route transactions through a single domestic switch increase the risk of “a single point of failure” and can undermine security rather than enhance it.

Effective payment systems depend on data mobility. Limiting cross-border data transfers reduces the robustness, security, and innovation capacity of financial services. Principle-based data protection frameworks that allow data to flow while ensuring adequate safeguards are identified as more effective than localization mandates.

Government initiatives

Governments across Asia are pursuing domestic, bilateral, and regional initiatives to improve interoperability and efficiency in cross-border e-payments. Efforts such as the ASEAN Cross-Border Payments Interoperability Network (XBPIN) aim to link national payment systems under common rules. However, harmonizing legal, technical, and operational standards is politically and technically demanding, and many such schemes have failed to meet expectations, accounting for only a small share of actual cross-border retail payments.

Trade agreements and digital economy frameworks are emerging as alternative vehicles for progress. Digital Economy Agreements and partnerships increasingly include commitments on open banking, innovation facilitation, and the adoption of international standards such as ISO 20022. These frameworks seek to create a “network of networks” for payments by encouraging interoperability and data sharing.

Commitments to reduce market access barriers are also embedded in regional and bilateral trade agreements, reinforcing principles such as national treatment, limits on data localization and restrictions on forced domestic infrastructure requirements. Payments-related cooperation at forums such as the World Trade Organization and Group of 20 further highlights the growing recognition of cross-border payments as a systemic policy challenge.

Conclusion

Facilitating safe, efficient, and interoperable cross-border e-payments would unlock significant gains for Asia’s regional economy, particularly for MSMEs. Lower costs, faster settlement, and greater transparency would allow smaller firms to view the region as their natural marketplace rather than a collection of fragmented national systems. Without meaningful progress on interoperability, data governance and market access, cross-border payments will remain a bottleneck on Asia’s digital trade ambitions even as domestic digital payments continue to surge.
