A quiet revolution in cross-border payment infrastructure is unfolding across Southeast Asia, Africa, and Latin America, as central banks and fintech consortiums accelerate the deployment of interoperable digital payment systems. By linking domestic instant payment rails across national borders, these initiatives aim to slash remittance costs, expand financial inclusion, and reduce dependency on legacy correspondent banking networks.
The Bank for International Settlements has identified more than 30 active projects linking national fast payment systems, up from just five in 2021. The Nexus project — a BIS Innovation Hub initiative connecting the instant payment systems of Malaysia, the Philippines, Singapore, Thailand, and India — completed its first live cross-border transactions earlier this year, processing payments in under 60 seconds at a fraction of traditional wire transfer costs.
“For the 1.4 billion people who remain unbanked globally, these interconnected payment rails represent something more fundamental than convenience — they are an on-ramp to the formal financial system,” said Maria Okonkwo, director of digital finance at the Alliance for Financial Inclusion. “When a farmer in Kenya can receive payment from a buyer in Singapore in seconds at near-zero cost, the economics of small-scale trade transform.”
The technology underpinning these networks increasingly relies on standardised QR code protocols and the ISO 20022 messaging standard, creating a common language for financial transactions that spans jurisdictions. Central bank digital currencies are emerging as a complementary layer, with 134 countries now exploring CBDCs, up from 35 in 2020, according to the Atlantic Council’s CBDC tracker.
Remittance costs remain stubbornly high in corridors lacking competition, averaging 6.4 percent globally for sending $200 — more than double the United Nations Sustainable Development Goal target of 3 percent. The new cross-border networks have demonstrated the potential to bring costs below 2 percent, though achieving this at scale requires regulatory harmonisation that remains politically complex.
Private sector participants are also expanding their footprint. Ant Group’s Alipay+ now connects more than 25 mobile payment providers across Asia and Europe, while Visa and Mastercard have invested heavily in real-time account-to-account infrastructure. The competition between bank-led, central bank-led, and private-sector models is likely to define the payments landscape for the next decade.
The European Central Bank’s digital euro project, now in its preparation phase with a potential 2028 launch window, is being closely watched as a template for how major reserve currency areas might approach the intersection of sovereign digital money and cross-border interoperability. Whatever model prevails, the direction of travel appears irreversible: the era of three-day international wire transfers is drawing to a close.
