The issue confronting ASEAN’s cross-border payments ecosystem is no longer one of technical feasibility. It is a question of scale, governance, and political follow-through. Malaysia’s experience over the past six years, anchored in its DuitNow real-time payments infrastructure, offers a clear illustration of both how far the region has come and how much remains unresolved as ASEAN moves toward the multilateral ambitions of Project Nexus in 2026.
Malaysia today sits at the centre of ASEAN’s most mature set of bilateral retail payment linkages. DuitNow, overseen by Bank Negara Malaysia (BNM) and Payments Network Malaysia, has been progressively connected to neighbouring real-time payment systems, beginning with Singapore’s PayNow in 2019, followed by Thailand’s PromptPay, and more recently, Indonesia’s QR-based payment ecosystem. These links allow consumers and small businesses to make cross-border payments using familiar domestic banking or wallet applications, with currency conversion occurring seamlessly at the point of transaction.
The significance of these arrangements lies not in novelty but in proof. For years, ASEAN policymakers spoke about interoperability as an aspiration, often framed in abstract terms. Malaysia’s bilateral corridors have demonstrated that interoperability can work across jurisdictions with differing regulatory philosophies, consumer protection regimes, and market structures. Transactions are settled in near real time, costs are materially lower than card-based or correspondent banking alternatives, and user experience remains largely frictionless.
These successes, however, have also exposed the limits of a purely bilateral approach. Each linkage has required bespoke governance arrangements, commercial negotiations between payment operators, and careful calibration of risk controls. Scaling this model across ASEAN’s ten member states would result in an increasingly complex web of point-to-point connections, raising costs and operational fragility. It is this reality that has propelled Project Nexus to the forefront of regional payments policy discussions.
Project Nexus, coordinated by the Bank for International Settlements’ Innovation Hub in partnership with ASEAN central banks, aims to link domestic instant payment systems through a single multilateral infrastructure using standardised application programming interfaces. For Malaysia, the initiative represents both an opportunity and a test. The country enters the Nexus phase with more practical experience than most peers, but also with heightened exposure to the trade-offs that multilateral interoperability entails.
From a policy perspective, the core challenge is alignment rather than technology. Anti-money laundering and counter-terrorism financing requirements vary across ASEAN, as do thresholds for transaction monitoring and reporting. While DuitNow’s bilateral links have relied on mutual comfort between specific regulators, Nexus will require broader trust among a larger group of authorities. For BNM, this means balancing Malaysia’s established risk-based supervisory approach with the need for mutual recognition mechanisms that do not dilute domestic safeguards.
Small and medium-sized enterprises remain the most frequently cited beneficiaries of deeper interoperability, and not without reason. Malaysian SMEs engaged in regional trade routinely report delays in receiving cross-border payments, unpredictable foreign exchange spreads, and opaque fee structures. While bilateral DuitNow corridors have reduced friction in specific markets, their coverage remains uneven. Nexus promises to widen the addressable footprint, but only if settlement certainty and pricing transparency can be maintained at scale.
Tourism and migrant remittances also feature prominently in Malaysia’s interoperability narrative. Cross-border QR payments have already changed spending behaviour among Singaporean and Thai visitors, who increasingly rely on domestic apps rather than international cards. Extending similar convenience across a wider set of ASEAN markets would further reduce dependence on legacy networks, but it also shifts responsibility for dispute resolution and consumer redress onto domestic frameworks that were not originally designed for cross-border use.
Another unresolved issue is foreign exchange settlement. While payment messages may move instantly, underlying FX conversion often still depends on traditional banking arrangements. Malaysia’s experience has shown that without deeper liquidity arrangements or multilateral settlement mechanisms, some of the efficiency gains of real-time payments risk being eroded behind the scenes. This remains an open question as Nexus approaches its targeted launch window.
Competition within ASEAN adds another layer of complexity. Singapore positions itself as the region’s financial hub, Thailand leverages tourism-driven volumes, and Indonesia brings sheer market scale. Malaysia’s comparative advantage lies in execution. DuitNow’s steady expansion reflects a regulatory culture that favours incremental progress over grand announcements. Whether this pragmatism translates into influence within Nexus governance structures will shape Malaysia’s role in the next phase of ASEAN payments integration.
As the year unfolds, the payments debate has matured. The question is no longer whether ASEAN can build interoperable payment rails. Malaysia’s bilateral track record answers that decisively. The real issue is whether ASEAN, through initiatives like Nexus, can construct governance frameworks that match technical ambition with financial stability, consumer trust, and commercial sustainability.
Malaysia’s journey suggests cautious optimism. Bilateral success has created momentum, but multilateral interoperability will demand harder choices. If Nexus delivers on its promise, it will mark a structural shift in how money moves across Southeast Asia. If it falters, ASEAN risks remaining a region of impressive pilots but incomplete integration. For Malaysia, the coming year will reveal whether practical experience can be converted into regional leadership in the next chapter of digital payments.
