US merchants face billions in lost Southeast Asia sales as local payment rails entrench
The transactions happen at scale whether or not a US merchant sits on the other side.
Mark
Why can't American payment networks just adapt to these local systems? They have the scale and the resources.
Mimi
Because these rails were not built for outsiders. They were built by governments and central banks to serve their own citizens. The regulations, the bank relationships, the settlement flows—all of it is optimized for domestic transactions. An American network trying to plug in would have to fundamentally reimagine how it operates in each market.
Mark
So the problem is that US merchants need to integrate with each local system separately?
Mimi
That is part of it. But the deeper problem is that most merchants have priced that work and decided it is not worth it. They look at the cost of integrating with DuitNow, then InstaPay, then PayNow, and they decide to accept that they will only reach the customers who have cards.
Mark
But if a hub launches in 2027 that connects all these systems, won't that solve the problem?
Mimi
It will help enormously. But only for merchants who have already done the integration work. The merchants who wait until 2027 will still have to integrate with each local rail. The ones who move now will suddenly be able to reach six countries through a single connection.
Mark
Is there a reason these governments are building this infrastructure now, rather than just letting card networks dominate?
Mimi
Because card networks never reached most of their citizens. Account-to-account systems are cheaper, faster, and require nothing more than a bank account. Once governments saw that their own people preferred these methods, they invested in making them better. Now they are making them interoperable.
Mark
What happens to the merchants who do not integrate?
Mimi
They compete for a shrinking slice of the market. The customers who have cards will still use them. But everyone else—the vast majority—will transact elsewhere. In billions of dollars.
The Pulse
- Billions of dollars in Southeast Asian transactions are completing every year without a single US merchant on the receiving end, because the region's payment rails were built for local banks, not American card networks.
- Malaysia, the Philippines, and Singapore have each restructured their national clearing systems in ways that signal permanence — these are not experiments regulators expect to fade, but foundations governments are actively reinforcing.
- The consumer on the other side of the failed transaction has not rejected American goods; she is simply paying through the app her bank built into her phone, a method that requires only a national ID and a bank account rather than a credit card she may never qualify for.
- Integrating with each local rail individually demands years of compliance work, separate settlement flows, and market-by-market launches — a cost so high that most US merchants quietly accept the loss and move on.
- A six-country payment hub called Nexus Global Payments, incorporating India, Malaysia, the Philippines, Singapore, Thailand, and Indonesia, is scheduled to go live in 2027, and merchants already integrated with local rails will reach all six markets through a single connection while latecomers watch from outside.
Across Southeast Asia, hundreds of millions of consumers have quietly built a financial world that runs on rails American merchants were never invited to join. Homegrown instant-payment systems in Malaysia, the Philippines, and Singapore have grown from conveniences into the primary architecture of daily commerce — not by displacing cards, but by making them irrelevant. US merchants who built their global strategies around card networks are now standing at a checkout counter that does not speak their language, watching billions in potential sales route to someone else. The window to adapt is narrowing, and the infrastructure being assembled will soon determine who belongs to this market and who merely observes it.
American merchants selling into Southeast Asia are watching billions of dollars in transactions happen without them. The region's homegrown payment systems — DuitNow in Malaysia, InstaPay in the Philippines, PayNow in Singapore — have grown so deeply embedded in local banking infrastructure that they are no longer alternatives to card networks. They are the primary way people pay, and most US retailers have no way to accept them.
The numbers are not subtle. Malaysia processed 18.4 billion e-payment transactions in 2025, up a quarter from the year before. The Philippines pushed the equivalent of $24.7 trillion through InstaPay and PESONet, with volume tripling to 4.8 billion transactions. Singapore's unified QR standard now covers more than 130,000 acceptance points. These are not niche methods. This is how the region actually pays.
The entrenchment is not accidental. Governments have made deliberate choices to consolidate and strengthen these rails. Malaysia restructured its payment infrastructure through PayNet. The Philippines merged BancNet with its clearing house. Singapore unified eight separate payment schemes under a single governing body. When states restructure their clearing systems, they are signaling permanence — and these signals are unmistakable.
For US merchants, the solution sounds simple but is anything but. Integrating with each local rail individually means separate compliance work, distinct settlement flows, and years of market-by-market launches. Most settle for what card networks reach and quietly abandon the rest of their potential customers — choosing the known loss over the uncertain cost of doing it right.
What is changing is that the cost of doing it right is about to fall. In 2025, the central banks of India, Malaysia, the Philippines, Singapore, and Thailand incorporated Nexus Global Payments, a hub designed to link their instant payment systems through a single connection. Indonesia joined in 2026, and the system goes live in 2027. A merchant already integrated with local rails will suddenly reach customers across six countries through one interface. A merchant who has not will be watching from the outside, hoping customers eventually acquire a card. Few will.
American merchants selling into Southeast Asia are watching billions of dollars in transactions happen without them. The region's homegrown payment systems—DuitNow in Malaysia, InstaPay in the Philippines, PayNow in Singapore—have grown so large and so deeply rooted in local banking infrastructure that they are no longer alternatives to card networks. They are the primary way people pay. And most US retailers have no way to accept them.
The numbers tell the story. Malaysia processed 18.4 billion e-payment transactions in 2025, up a quarter from the year before. DuitNow QR codes alone doubled to 3 billion transactions across nearly 3 million merchant locations. The Philippines pushed the equivalent of $24.7 trillion through InstaPay and PESONet, with transaction volume tripling to 4.8 billion. Singapore's unified QR code standard now sits at more than 130,000 acceptance points. These are not niche payment methods. These are how the region actually pays.
For American exporters, the math is stark. The Small Business Administration counts 1.3 million US small-business exporters competing for a global market of 2.6 million potential customers. Nearly 96 percent of the world's consumers live outside the United States. Southeast Asia is wealthy, growing, and hungry for American goods. But when a customer in Jakarta or Manila reaches checkout, they encounter a system built for American cards—a payment method many of them do not have and do not want to get. The transaction fails. The sale does not happen. The customer buys from someone else.
The reason these local rails have become so entrenched is not accident. Governments across the region have made deliberate choices to strengthen them. Malaysia consolidated its payment infrastructure through PayNet. The Philippines merged BancNet with its clearing house. Singapore placed eight separate payment schemes under a single governing body. These are not the actions of regulators expecting these systems to fade away. They are the actions of governments building permanent infrastructure. When a state restructures its clearing systems, it is signaling that those systems are here to stay.
The design of these rails also matters. Unlike credit cards, which require consumers to meet minimum thresholds and navigate complex issuance processes, account-to-account payment systems ask only for a national ID and a bank account. InstaPay overtook ATM withdrawals in volume and value back in 2020. DuitNow and FPX require nothing more than electronic banking access. The consumer at the far end has not rejected American products. She is simply paying through the method she already uses every day—the method her bank built into her phone.
For American merchants, the solution sounds simple but is anything but. They could integrate with each local rail individually. But that means years of work: new integrations for each market, separate compliance work for each jurisdiction, distinct settlement flows for each country. A merchant expanding into dozens of markets cannot afford to spend a year launching each payment option one by one. So most settle for what card networks reach and abandon the rest of their potential customers. They are choosing the known loss over the uncertain cost of doing it right.
What is changing now is that the cost of doing it right is about to drop. In March 2025, the central banks of India, Malaysia, the Philippines, Singapore, and Thailand incorporated Nexus Global Payments, a hub designed to link their instant payment systems through a single connection. Indonesia joined in 2026. The system is scheduled to go live in 2027. When it does, a merchant who has already integrated with these local rails will suddenly be able to reach customers across six countries through a single interface. A merchant who has not will be watching from the outside.
The merchants who move first will have an advantage that compounds over time. They will collect payments through a dozen local networks but settle into a single currency, simplifying their treasury and their accounting. They will be present at checkout with the payment methods their customers already trust. The merchants who wait will be hoping those customers eventually acquire a card. Few American merchants will manage the integration without help from firms that already have the infrastructure in place across these markets. The window to be early is closing. The transactions are happening at scale whether or not a US merchant sits on the other side.
