In Jakarta’s Tanah Abang market, a textile wholesaler who has stitched bedsheets for two decades now spends her mornings refreshing a fuel-price app. In Ho Chi Minh City, a small logistics operator has begun adding a surcharge that his customers do not yet know about. In Cebu, a furniture exporter is quietly cutting his sales forecast for the third time this year. None of them has ever met. All three are about to walk into a bank and ask, politely, whether the terms of their working-capital line might be reconsidered.
Multiply these encounters by several million, scatter them across ten economies, and one begins to see the shape of the year ahead for banks across the Association of Southeast Asian Nations. Micro, small, and medium-sized enterprises (SMEs) account for 97% of private-sector firms in the region and 85% of its jobs1. They are the spine of ASEAN’s growth story — and that spine is now under unusual compression.
For most of the past three years, the mood in ASEAN SME banking has been buoyant, occasionally giddy. Digital lending platforms have grown at triple-digit rates as fintechs sliced credit assessments into ever-finer instruments. Sustainable finance, once a marketing flourish, has become a serious line of business: UOB booked S$7 billion in green and transition financing in the first half of 2025 alone2, matching its entire 2024 total. Maybank, in unveiling its M30 strategy, has pledged RM100 billion in SME financing and RM300 billion in sustainable finance by 20303— figures that would have seemed fanciful a decade ago. OCBC, not to be outdone, announced in April that it would target 12,000 SMEs across its four core markets with integrated sustainable finance commitments of S$25 billion by 20284. The Asian Development Bank estimates the region needs roughly $210 billion a year of ESG-aligned infrastructure investment through 20305 to keep up with itself. The ambition is real. The market is large. The runway, on paper, looks long.
And then the runway tilted. The American and Israeli campaign against Iran, now in its second quarter, has done what most geopolitical shocks do to ASEAN: arrived obliquely, but firmly. Crude prices have stayed elevated long enough to widen import bills in Vietnam, Thailand, the Philippines, and Indonesia — the four net oil importers that together drive most of the region’s manufacturing churn. Vietnam’s central bank, in its April monetary review, conceded that the country’s 10% growth aspiration for 2026 looks increasingly contingent on energy stabilization6 Maritime insurance premiums on the Hormuz and Bab-el-Mandeb corridors have jumped. Remittances from Gulf-based workers — a quiet but consequential prop for Filipino and Indonesian household consumption — are softening. President Trump’s tariff architecture, layered atop all this, has begun to bite small exporters who lack the lawyers to navigate it.
The result, predictably, is credit stress, and the data are no longer subtle. In Thailand, the central bank’s 2025 Financial Stability Review noted that micro-SMEs experienced the largest contraction in credit of any borrower category last year and paid higher interest rates than larger corporates for the privilege; less than half of Thai SMEs can currently obtain a bank loan at all. The IMF’s April 2026 Article IV consultation on Thailand was blunter still, calling SME credit risks “elevated, with notable deterioration.” Indonesia’s picture is, if anything, starker: MSME financing fell by 17.64% between 2024 and 2025, from IDR 180.48 trillion to IDR 148.65 trillion7 — a contraction that dwarfs the carefully hedged provisioning language emerging from Hanoi. In Vietnam itself, Techcombank’s April macroeconomic note flagged rising provisioning pressure in its SME book; VPBank and Military Bank have made similar, if more euphemistic, noises. In Malaysia, Maybank has begun publicly leaning on “ecosystem and beyond-banking solutions” to keep SMEs on its books at all. The classic bind, in other words, region-wide: more risk, less revenue, and a regulator that has not loosened its grip on capital adequacy.
Faced with this, the temptation for any bank is to reach for the bluntest instrument in the cupboard — across-the-board rate increases, tightened covenants, a quiet retreat from segments that suddenly look unlovable. The temptation should be resisted. ASEAN’s SME segment is not a single asset class behaving uniformly; it is several thousand micro-portfolios, each responding to oil, tariffs, remittances, and exchange rates in different proportions. A blanket repricing punishes the resilient alongside the wobbly and tends to chase precisely the customers a bank ought to keep.
What the moment calls for, instead, is precision. Banks that can price each SME relationship on its actual economics — fee income, deposit balances, FX flows, trade finance volumes, sustainability profiles will find themselves with both fatter margins and stickier customers. Those that cannot will be reduced to a familiar choreography: cut the rate to win the deal, then discover at quarter-end that the deal was unprofitable all along. Relationship managers know this. Their pricing systems, in most banks, do not.
There is a second move available, and it is one of the best that banks in the region are beginning to make. Working capital, trade finance, FX hedging, and cash management are typically sold to SMEs as discrete products, priced discretely, and abandoned by the customer discretely when a competitor offers ten basis points less on any one of them. Packaged together — as a propositioned bundle that reflects the customer’s actual life rather than the bank’s product silos — they become considerably harder to dislodge. OCBC’s April 2026 announcement, with its target of 12,000 SMEs and S$25 billion in integrated sustainable finance commitments by 20288, is effectively a bundling thesis dressed in green: the bank is betting that an SME which takes its ESG diagnostic, its sustainability-linked loan and its trade finance from one institution is structurally less likely to defect over ten basis points. It is the right bet. The barrier, for most banks, has rarely been strategic conviction. It has been the core banking system, which was built in an era when bundling meant a brochure rather than a billing engine.
Then there is the green question, which is no longer optional. Access to international supply chains, and to the capital that funds them, increasingly turns on ESG readiness. The architecture is starting to appear – SME Bank Malaysia’s High Tech and Green Facility offers explicit preferential pricing to SMEs that qualify on green or high-tech criteria, an early example of what differentiated ESG pricing looks like when operationalized at the loan level rather than the press release level. The institutions that can replicate this at scale — pricing a green SME loan distinctly from a brown one, tracking sustainability KPIs at the facility level, and producing credible reports for both regulators and counterparties — will find themselves with a moat that compounds. Those that cannot will find themselves selling a commodity in a market that has decided to pay for differentiation.
The fourth, and perhaps most underappreciated, opportunity is in the ecosystem itself. Advisory services, ESG diagnostic tools, and supply-chain financing platforms are fee-based revenues that sit naturally adjacent to the SME relationship and require no further balance-sheet expansion. They are also, conveniently, the kind of services SMEs are now actively asking for, having discovered in the past quarter that they understand their own cost base less well than they thought. OCBC’s SME ESG Assessment tool — known internally as SMEEA — and Maybank’s broader M30 “beyond-banking” ecosystem are early but instructive examples of fee-based adjacency being operationalized. Both treat the SME relationship as a platform rather than a product, and both depend, quietly, on the ability to price and bill for services that older systems were never designed to recognize as revenue.
None of this requires ripping out the core. The banks that learn this fastest will be the ones that treat their existing systems as foundations rather than prisons — layering precision pricing, bundling, ESG-linked products, and ecosystem monetization on top of what is already there, rather than embarking on the kind of multi-year transformation program that tends to outlive the executives who commissioned it. The technology to do this exists. The question is whether the appetite to deploy it arrives before the next quarter’s provisioning numbers do.
The textile wholesaler in Tanah Abang, the logistics operator in Ho Chi Minh City, the furniture exporter in Cebu — they will, in some combination, walk into their banks over the coming months. What they hear back will determine rather more than the fate of their own businesses. ASEAN’s growth model has rested, quietly and largely uncomplainingly, on the willingness of its banks to keep the SME spine flexible. That willingness is about to be tested in earnest. The banks that pass the test will not be the ones with the largest balance sheets. They will be the ones that knew, line by line and relationship by relationship, what each customer was actually worth.
The next article in this series will examine how leading ASEAN banks are reconfiguring their SME propositions for an era of compressed margins and ESG acceleration — and what separates the institutions getting it right from the ones still hoping the cycle will turn before they have to.
