For Malaysia’s small and medium-sized enterprises, cross-border payment reform is not an abstract policy discussion. It is a daily operational constraint that directly affects cash flow, pricing competitiveness, and regional expansion plans. As ASEAN central banks move closer to multilateral payment interoperability through initiatives such as Project Nexus, SMEs remain both the most vocal beneficiaries and the most exposed stakeholders in the transition.
Despite years of digitalisation rhetoric, SME payment frictions across Southeast Asia remain stubbornly persistent. Malaysian exporters supplying neighbouring markets frequently encounter settlement delays ranging from one to five business days when relying on correspondent banking channels. Fees, including foreign exchange spreads, intermediary charges, and receiving bank deductions, are often opaque and difficult to reconcile. For smaller firms operating on thin margins, these costs are not incidental. They shape decisions on whether cross-border trade is viable at all.
Malaysia’s DuitNow-linked corridors have begun to change this dynamic in specific markets. Connections with Singapore’s PayNow and Thailand’s PromptPay allow eligible SMEs to receive payments almost instantaneously using domestic banking applications. Currency conversion occurs at the point of transaction, reducing uncertainty over final settlement amounts. For micro-merchants and service providers, particularly those operating in border regions or tourism-linked supply chains, this has translated into faster receivables and lower working capital strain.
However, the benefits remain uneven. DuitNow’s bilateral nature means that SMEs trading beyond connected markets continue to face legacy frictions. An exporter dealing with buyers in Vietnam or the Philippines, for example, cannot yet rely on the same real-time settlement experience. This uneven landscape creates a two-speed ASEAN, where efficiency gains accrue selectively rather than systemically.
Project Nexus is intended to address precisely this fragmentation. By linking domestic instant payment systems through a single multilateral framework, Nexus promises to reduce the need for bespoke bilateral arrangements. For SMEs, the appeal lies in scale. A single integration could unlock access to multiple markets without requiring separate payment onboarding processes, contractual negotiations, or technical adaptations.
Scale introduces new risks still. SMEs often lack the compliance infrastructure of larger corporates, raising questions about how anti-money laundering and know-your-customer requirements will be applied consistently across borders. Malaysian regulators have signalled a risk-based approach, but mutual recognition among ASEAN authorities remains a work in progress. For SMEs, uncertainty over compliance obligations can be as inhibiting as high fees.
Another challenge lies in foreign exchange pricing. While real-time payments reduce settlement delays, they do not automatically guarantee competitive FX rates. SMEs frequently report that smaller transaction sizes attract wider spreads, even on digital platforms. Without transparent benchmarks or competitive liquidity pools, interoperability risks delivering speed without affordability. Policymakers are increasingly aware of this issue, but solutions remain nascent.
The invoicing ecosystem adds further complexity. Many Malaysian SMEs still rely on manual or semi-digital invoicing processes, which do not integrate seamlessly with payment platforms. Real-time payments only deliver full efficiency gains when paired with digital invoicing, reconciliation, and accounting tools. Some fintech providers are attempting to bridge this gap, but adoption remains uneven, particularly among traditional family-owned businesses.
From a policy standpoint, SMEs serve as both justification and stress test for ASEAN payment reform. They are frequently cited as the primary beneficiaries of interoperability, yet their operational realities expose the weakest links in the system. If Nexus fails to accommodate SME constraints around compliance, cost transparency, and ease of use, its impact risks being skewed toward larger firms better equipped to absorb complexity.
Malaysia’s experience offers cautious lessons. DuitNow’s success has been driven by gradual rollout, extensive stakeholder engagement, and a focus on user familiarity. SMEs transact using the same interfaces they already trust domestically. Replicating this simplicity at a multilateral level will be significantly harder. Governance frameworks must be robust without becoming burdensome, and innovation must not outpace adoption capacity.
SMEs are watching closely. For many, ASEAN integration remains more promise than reality. The next phase of payment interoperability will determine whether regional trade becomes genuinely accessible to smaller firms or remains dominated by those able to navigate cost, compliance, and complexity. In this sense, SMEs are not merely beneficiaries of payment reform. They are the metric by which its success will ultimately be judged.
