Last week, I wrote about Southeast Asia’s quiet shift from apps to architecture — the infrastructure, capital, and talent layers being laid beneath the region’s digital finance story. This week, three more developments arrived that take that thesis a level further. The region is not just building the pipes. It is now, with increasing seriousness, writing the rules for what flows through them.

Vietnam: Southeast Asia’s First AI Law Is Now in Force
#

On March 1, 2026 — the same day I published last week’s column — Vietnam’s Law on Artificial Intelligence (Law No. 134/2025/QH15) officially took effect, making Vietnam the first country in Southeast Asia to enforce a comprehensive, binding AI legal framework.

The scope of the law is deliberately broad. It covers the full lifecycle of AI systems: research, development, provision, deployment, and use. Both Vietnamese organizations and foreign entities whose systems affect Vietnamese users or interests fall under its remit — including a requirement for foreign providers to appoint a local legal representative. The law is structured around a three-tier risk classification: high-risk systems (those touching healthcare, finance, education, critical infrastructure, or government services) face the strictest pre-market conformity requirements, ongoing monitoring, and mandatory human oversight. Lower-risk systems carry proportionally lighter obligations.

For fintech specifically, the implications are immediate. AI-driven credit scoring, fraud detection, identity verification, and algorithmic lending are all squarely in high-risk territory. Any institution deploying these systems in Vietnam now operates under a legal obligation to demonstrate conformity, maintain audit trails, and ensure a human can review and override AI-generated decisions.

Two other provisions stood out to me. First, the law requires that all AI-generated content — including deepfakes — be clearly labelled, and that users must be informed whenever they are interacting with an AI system rather than a human. For the digital banking context, this matters: robo-advisory interfaces, automated customer service agents, and AI-assisted loan applications all need disclosure mechanisms built in. Second, Vietnam has embedded a regulatory sandbox scheme into the law itself, allowing selected projects to receive exemptions or relaxed obligations through an accelerated evaluation process. This is the “management-for-development” framing that the Vietnamese government has consistently used to describe its approach — balancing risk control with an explicit policy commitment to AI as an economic driver.

The Straits Times noted that Vietnam joins a small group of countries globally with binding AI legislation — South Korea began enforcing a similar law in January, and the EU is rolling out its AI Act through 2027. The United States, by contrast, has moved in the opposite direction. Vietnam’s move is especially significant because it provides a concrete governance model that neighbouring ASEAN states can observe, adapt, and learn from. Whether Malaysia, Thailand, or Indonesia eventually follow with their own frameworks — or whether an ASEAN-level approach emerges — will be one of the more consequential regulatory stories of the next two or three years.

For product teams building AI-enabled financial services across the region, the practical message is straightforward: the era of deploying AI into regulated financial contexts under vague voluntary guidelines is ending. Vietnam has moved first. Others will follow.

Money20/20 Asia: APAC Fintech Has Left the Pilot Stage
#

On March 6, Money20/20 released its Future of Fintech in APAC report — an annual survey-backed assessment of the region’s fintech ecosystem, drawing on responses from over 130 senior industry leaders. The headline finding is worth stating plainly: APAC fintech has moved from experimentation to production-grade deployment, and the region is increasingly seen as a global blueprint rather than a case study in potential.

A few numbers from the report stood out:

  • 61.2% of surveyed organisations have already adopted AI or machine learning — not exploring or piloting, but deployed.
  • 22.9% of respondents named APAC as their primary growth market for 2026, confirming that the region draws not just regional operators but global capital and talent.
  • 63.5% of leaders cited fraud prevention as their highest operational priority — a reflection of the tension between rapid digital adoption and the security infrastructure required to support it sustainably.
  • 90.6% of executives reported that social good initiatives are now embedded in corporate strategy, which signals that financial inclusion has crossed from mission statement to commercial imperative.

The stablecoin data in the report deserves particular attention. New regulatory frameworks in Singapore, Hong Kong, and Japan are driving institutional adoption of stablecoins and tokenized financial instruments — with such instruments increasingly used for payments, cross-border settlements, and treasury optimization. Ian Fong, VP of Content at Money20/20 Asia, framed the overarching shift with clarity: “APAC is no longer experimenting — it’s executing.”

That phrase maps directly to what I observed last week. The DBS-Visa agentic payment pilot, the Maya and GCash IPO preparations, Bank Indonesia’s innovation talent hub — these are not early-stage experiments. They are institutional bets on infrastructure that the players expect to be operating for a decade. The Money20/20 data adds the industry-wide confirmation that this maturation is not confined to a handful of flagship firms. It is a regional pattern.

One concern the report surfaces is worth acknowledging. The same speed of digital adoption that is producing these numbers has also outpaced traditional fraud and security models. Building financial systems that are both faster and safer simultaneously is genuinely hard — and the gap between adoption velocity and security maturity is where consumer harm tends to concentrate. The 63.5% fraud prevention figure is not just a prioritization signal; it is an admission that this is also where the system remains most vulnerable.

UBS OneASEAN Summit: The Investment Case Is Consolidating
#

On March 5, UBS gathered more than 850 institutional investors, policy makers, and industry leaders for the 14th edition of the UBS OneASEAN Summit in Singapore. The GDP forecast headline — 4.9% growth for the ASEAN-6 (Indonesia, Malaysia, Philippines, Singapore, Thailand, and Vietnam) in 2026 — is the kind of number that tends to move asset allocation conversations.

Grace Lim, UBS Investment Bank’s senior ASEAN and Asia economist, attributed the growth outlook to three factors: deep integration into global manufacturing value chains, household consumption momentum in Indonesia, and resilient tech-related export strength in Singapore and Malaysia. Nicolo Magni, UBS Global Banking’s head for South-East Asia and South Asia, added that Southeast Asia “continues to be a strategic alternative for investors,” with active deal-making expected across healthcare, real estate, and consumer sectors through 2026.

The framing of ASEAN as a “strategic alternative” is telling. In the context of ongoing US-China trade tensions and supply chain realignment, Southeast Asia has become the destination of choice for manufacturers and investors looking to diversify exposure. That dynamic drives not just FDI in manufacturing but downstream investment in the payments, logistics, and financial services infrastructure that trade networks require. The fintech opportunity in a region processing ever-larger volumes of manufacturing-linked commerce is not incidental to the macro story — it is structurally embedded in it.

Alongside the summit, an update from the Philippines provided a concrete example of that infrastructure buildout in real time. BSP Deputy Governor Mamerto Tangonan confirmed on March 2 that the Philippines is making progress toward its integration into Project Nexus, the Bank for International Settlements’ multilateral instant payment initiative. Indonesia recently became the sixth central bank partner in the network, joining Singapore, India, Malaysia, Thailand, and the Philippines. The platform is currently being built, with the Philippines targeting a mid-2027 onboarding.

The context Tangonan provided was striking: e-payment transactions in the Philippines reached ₱24.74 trillion in 2025 — a 42% increase from 2024 — and now represent 90% of GDP. For a country where basic financial access was a persistent challenge a decade ago, that number reflects a structural transformation.

The Governance Layer Takes Shape
#

Read together, these three developments point toward the same underlying shift. For much of the past decade, the dominant narrative around Southeast Asia’s digital economy was about potential: the unbanked populations, the mobile-first leapfrogging, the unicorns emerging from markets that traditional finance had overlooked. That story generated real investment, real companies, and real impact.

The narrative this week is different. Vietnam’s AI law signals that the region’s governments are no longer willing to let the rules be written by default — by global platforms, by regulatory gaps, or by the delayed outcomes of voluntary guidelines. The Money20/20 data confirms that the industry has passed the experimentation threshold and is operating at scale. The UBS summit and Project Nexus update show that the capital and the cross-border infrastructure are being aligned to match.

None of this means the work is done. Vietnam’s law will be tested in its implementation — enforcement capacity, jurisdictional reach over foreign providers, and the practical functioning of the sandbox scheme are all open questions. The fraud and security challenges flagged in the Money20/20 report require sustained investment and industry-regulator coordination that does not happen automatically. Project Nexus is still being built.

But the direction is unmistakable. Southeast Asia’s digital economy is no longer making its case to be taken seriously. It is setting the terms.
