How ASEAN’s push for local-currency trade is meant to work

For decades, a large share of Asia’s cross-border trade and tourism has been settled in US dollars — even when neither party is American. Now a coordinated effort across Southeast Asia aims to let businesses and travellers transact directly in their own currencies. The umbrella idea is often called local-currency settlement, and it sits alongside a fast-growing network of linked instant-payment systems. This guide explains what ASEAN is building, why, and how far it can realistically go.

The problem local-currency trade tries to solve

Using the dollar as an intermediary step adds friction. Imagine a Thai importer buying goods from an Indonesian supplier. Under the traditional model, the importer may convert baht into dollars, then the supplier converts those dollars into rupiah. Each conversion carries a spread — effectively a fee — and exposes both sides to exchange-rate swings while the deal settles. Multiply that across millions of transactions and the costs add up.

There is a second concern. Relying heavily on one external currency means that interest-rate and policy decisions made far away can ripple into local financing costs and reserves. Smaller economies have limited control over those swings, which is one reason regional policymakers have looked for alternatives.

Two ideas advancing in parallel

1. Local-currency settlement frameworks

Central banks and commercial banks have been building frameworks that let trade be quoted and settled directly between two regional currencies, cutting out the dollar middle step. In practice this means appointing banks to make markets in currency pairs such as baht–rupiah or ringgit–rupiah, so an exporter can be paid in a currency it can actually use at home.

2. Linked instant-payment systems

Separately, several Southeast Asian countries have connected their domestic real-time payment systems. The visible result for consumers is cross-border QR payments: a traveller can scan a merchant’s QR code in another country and pay straight from their home banking app, with the conversion handled behind the scenes. This builds on the same open-rails philosophy that powers digital payments elsewhere in the region — see our explainer on India Stack, UPI and digital public infrastructure.

• Direct currency quotes remove a conversion and a spread.
• Linked QR payments let tourists and small traders pay in local money instantly.
• Settlement stays within the region’s own banking rails rather than routing through dollar accounts.

Who benefits first

The earliest and clearest gains show up in high-volume, lower-value flows:

1. Tourism — visitors paying merchants directly through linked QR systems.
2. Remittances — workers sending money home more cheaply.
3. Regional supply chains — manufacturers that already trade heavily with neighbours.

These are exactly the transactions where dollar conversion felt most wasteful, so they are where local-currency arrangements deliver the most obvious savings.

The limits: why the dollar is not going away

It is important to be realistic. None of this replaces the US dollar overnight, and that is not the stated goal. The dollar’s markets are extraordinarily deep and liquid, it is trusted worldwide, and for large or long-dated contracts businesses still value the certainty of a global reserve currency. Local-currency settlement also depends on banks being willing to hold and manage a wider range of regional currencies, which takes time to develop.

What is realistic is a steady reduction in friction between neighbouring economies that already do enormous business with one another. Over time, that lowers costs, deepens regional financial links, and gives Southeast Asia a bit more of its own financial plumbing — a quiet but meaningful shift explored further in why the Asia-Pacific drives global growth.

Part of a wider global trend

Southeast Asia’s effort is one strand of a broader, gradual move by many economies to reduce their dependence on a single currency for trade. The motivation is rarely ideological; it is usually practical — lowering costs, cutting exchange-rate risk and building resilience against shocks that originate elsewhere. What makes the ASEAN approach distinctive is its focus on everyday, high-volume flows such as tourism and small-business trade, where the benefits are immediate and easy to see, rather than on headline-grabbing reserve shifts.

It is also closely linked to the region’s leadership in digital payments. Because several ASEAN economies already run modern instant-payment systems, connecting them across borders is a natural next step — the same open-rails philosophy that powers India’s UPI.

What it means for businesses and travellers

For a small importer or exporter, local-currency settlement can mean fewer conversion fees and simpler pricing when trading with a neighbour. For a traveller, linked QR payments mean paying a street vendor or a shop in another country straight from a familiar app, often at a competitive rate and without hunting for a currency-exchange booth.

The changes are incremental and will not be visible everywhere at once, but the direction is clear: making it cheaper and simpler to move money between neighbouring economies that already trade heavily with one another — a core theme of why the Asia-Pacific drives global growth.

Frequently asked questions

What is local-currency settlement?

Local-currency settlement is an arrangement that lets businesses in two countries trade and pay directly in their own currencies, rather than converting both into US dollars as an intermediate step. It is designed to cut conversion costs and reduce exchange-rate risk.

Does ASEAN want to replace the US dollar?

No. The stated aim is to reduce reliance on the dollar for regional transactions and lower costs, not to replace it. The dollar remains dominant for large contracts and as a global reserve currency.

How do cross-border QR payments work?

Participating countries link their instant-payment systems so a traveller can scan a merchant’s QR code abroad and pay from their home banking app. The currency conversion happens automatically behind the scenes.

Who benefits most from local-currency trade?

Tourism, remittances and regional supply chains benefit first, because these are high-volume flows where dollar conversion added the most cost.

The bottom line

ASEAN’s push for local-currency trade is less a revolution than a steady re-plumbing of how money moves across Southeast Asia. By settling more trade directly and linking payment systems, the region is making everyday transactions cheaper and faster — while the dollar keeps its place at the top of the global system.
