The Asian Development Bank estimate targets a 50% reduction in compliance costs and 80% faster processing through digitisation, addressing the 6.5% average remittance cost globally.

The ADB Estimate and Its Significance

The Asian Development Bank estimates that digitising cross-border payment processing could reduce compliance costs by 50% and processing time by 80% (Source 1). This estimate arrives against a challenging baseline: the global average cost of sending $200 in cross-border remittances stood at 6.5% in Q1 2025, with South Asia the lowest region at 4.8% (Source 6, World Bank 2025). Even the most efficient regional corridors remain far above the UN Sustainable Development Goal target of 3% per transaction.

These costs are concentrated in legacy correspondent banking chains, where multiple intermediaries pass funds and instructions across borders, adding fees and compliance overhead at each step (Source 4). BIS research finds that transaction costs are higher in countries with more limited access to correspondent banking relationships (Source 6), a dynamic that disproportionately affects developing economies. According to one survey, the top three pain points for banks are differences in regulatory frameworks, AML/CFT requirements, and diverging privacy and security regulations across jurisdictions (Source 2). Each adds layers of manual review, redundant checks, and legal uncertainty that drive up both cost and settlement time.

The ADB's 50% compliance cost reduction estimate reflects the compounding effect of eliminating these frictions through end-to-end digital processing. The 80% faster processing figure captures the potential for near-real-time settlement when transaction chains are shortened from days to seconds.

How Digitisation Reduces Costs and Processing Time

The mechanism for achieving these improvements is structural, not incremental. Interlinking fast payment systems shortens transaction chains, enabling payment service providers to conduct transactions without using multiple payment systems or relying on correspondent bank intermediaries (Source 2). This eliminates the compounding of fees and FX margins that build at each intermediate step in the chain.

Enhanced AML and KYC processes through compliance-driven automation reduce manual overhead and bolster risk management (Source 3). Rather than each institution in a chain conducting duplicative checks, a single digital compliance layer can satisfy multiple jurisdictions' requirements, provided the underlying standards are aligned. EY analysis notes that these improvements in efficiency and security can simultaneously lower cross-border transaction costs, directly benefiting customers (Source 3).

Cross-border interoperability of national digital payment systems eliminates the need for currency conversions and simplifies money flows (Source 5). Most current digital payment systems are real-time payment systems; when integrated with each other, efficiency in cross-border transactions can be greatly enhanced. The result for end-users is reduced transaction fees, faster settlement, and lower currency conversion costs.

A non-trivial portion of current costs, however, is due to inefficiencies and frictions, not just legitimate compliance expenses (Source 6). The decline in correspondent banking networks over the past decade—evident in all regions—combined with rising payment volumes has concentrated market power and likely contributed to rent-seeking (Source 6). Digitisation addresses both the structural and the rent-seeking components of cost. Public sector support for developing domestic payment systems and harmonising rules can further lower compliance costs (Source 2), creating the infrastructure that private-sector innovation can build upon.

Challenges and the Path to Realising Gains

Realising the ADB's projected 50% cost and 80% time improvements requires overcoming significant coordination hurdles. Inconsistent implementation of rules and standards fragments interoperability and limits the benefits of digitalisation (Source 7). Even well-designed domestic fast payment systems fail to deliver cross-border efficiencies when they operate on incompatible technical standards, data formats, or regulatory frameworks.

The FSB report acknowledges that progress on the G20 roadmap for cross-border payments is not advancing as quickly as needed (Source 6). The roadmap, endorsed by G20 finance ministers in 2020, set ambitious targets for cost, speed, access, and transparency by 2027. With roughly one year remaining to the target deadline, the gap between ambition and implementation remains substantial.

Harmonising AML/CFT and data protection regulations across jurisdictions is necessary to reduce compliance burdens (Source 7). Since authorities responsible for AML/CFT regulations can vary from those responsible for payments systems or consumer protection, it is necessary to coordinate multiple domestic agencies, often with conflicting objectives (Source 7). Globally, the challenge multiplies. Open platform and public-good governance models, as advocated by the ECB, can avoid closed loops and discriminatory pricing (Source 2), ensuring that digitisation benefits accrue broadly rather than being captured by dominant platforms.

Innovation alone is insufficient; cross-border coordination and consistent implementation are equally critical (Source 6). The Asia-Pacific region, with its multiple bilateral and multilateral interoperability initiatives, demonstrates how marrying innovation and cross-border partnership can move the needle (Source 6). As public and private initiatives continue to align standards and build interoperable platforms, the ADB estimate provides a concrete benchmark for the cost and time savings that digitisation could unlock, contingent on coordinated global action.
