Every fortnight brings a fresh headline: another Southeast Asian fintech bolting stablecoin rails onto its payment stack, another central bank issuing a licence, another founder claiming to have solved remittances. The global stablecoin market has crossed roughly US$300 billion in market capitalisation, with transaction volumes running into the tens of trillions of dollars annually, a scale that now rivals the throughput of the major card networks.
Southeast Asia isn’t a bystander to this. It’s arguably the epicentre. Asia is the single largest stablecoin-flow region in the world, moving US$12.5 trillion in 2025 alone, up 67 per cent year-on-year, and within the region, 43 per cent of B2B cross-border payments in Southeast Asia already run on stablecoins.

The industry’s own telling of this story is a triumphant one: cheaper remittances, faster settlement, financial inclusion for the underbanked. All true. But sit with the numbers a little longer and a less comfortable story emerges — one about who actually controls Southeast Asia’s money, and whether the region’s regulators have fully clocked what they’ve signed up for.
The remittance math is genuinely extraordinary
Start with what stablecoins are unambiguously good at. The Philippines has upward of 10 million overseas workers, and its OFW remittance corridor moves close to US$40 billion a year. Traditional remittance rails charge migrant workers an average of 8.3 per cent globally to send money home, according to World Bank estimates, a tax on people who can least afford it.
Stablecoin-based transfers can undercut that to well below 0.1 per cent. That gap is not a rounding error; for a domestic helper in Singapore sending a third of her salary home every month, it is the difference between a decent transfer and a punitive one.
Singapore has positioned itself as the natural hub for formalising this. StraitsX, part of the Fazz Financial Group, now issues XSGD and XUSD and controls more than 70 per cent of the non-USD stablecoin market in Southeast Asia, with over US$18 billion in cumulative on-chain volume. It has embedded XSGD directly into GrabPay and struck a settlement partnership with KBank in Thailand, while extending its rails toward Taiwan and Japan, the kind of consumer-facing distribution that turns a crypto product into genuine financial infrastructure.
StraitsX’s CEO, Tianwei Liu, put the regional ambition plainly: Asia, he said, is “setting the pace for how stablecoins will power the next phase of global payments.” The Singapore-Indonesia corridor alone is now said to process around US$45 billion a year in cross-border flows, 89 per cent of it B2B — trade finance and supply-chain settlement, not speculative trading.
Six countries, six rulebooks, and founders are the ones paying for the gap
Here is where the optimism should get more qualified. Southeast Asia is not one stablecoin market; it’s at least six, each with a different regulatory philosophy operating at a different speed.
Singapore’s MAS has built arguably the clearest licensing pathway in Asia. The Philippines’ BSP treats stablecoins as a remittance-cost problem to solve, and licenses accordingly. Indonesia’s OJK and Bank Indonesia still classify crypto assets as commodities, not currency, leaving cross-border stablecoin payments to route through licensed money-transfer operators rather than direct rails.

Vietnam is the strangest case of all: the State Bank of Vietnam does not formally recognise crypto as a payment instrument, yet Vietnam ranks among the world’s most crypto-active markets, with informal USDT transfers already doing the work of a payments system that doesn’t officially exist, a pilot regulatory framework isn’t expected until later this year.
For a founder trying to build a single stablecoin payments product across the region, this fragmentation is not a minor compliance headache. It means Singapore-grade product assumptions can’t simply be copy-pasted into Jakarta, Hanoi or Manila. It means the “SEA stablecoin market” that investors pitch decks describe so tidily is, in practice, six separate licensing regimes, six separate AML expectations, and at least one jurisdiction (Vietnam) where the underlying activity is thriving in a formal vacuum.
The region’s stablecoin winners over the next two years will likely be decided less by who has the slickest product and more by who navigates this patchwork fastest without getting burned by it.
The dollarisation question nobody in the pitch decks wants to answer
The bigger, quieter concern sits one level up, at the central banks themselves. Almost every stablecoin flowing through these corridors is pegged to the US dollar. The Bank for International Settlements has now published research directly warning that this represents a new, digitally frictionless form of dollarisation, one that lets residents of emerging economies shift savings and payments into dollar tokens instantly and pseudonymously, in a way that physical dollar cash never allowed.
BIS researchers examined foreign reserve holdings across more than 130 countries alongside stablecoin inflow data and found a pattern with real financial-stability implications for developing nations. The IMF has gone further, warning that heavy dollar-stablecoin adoption could erode a central bank’s grip on interest rates and money supply, cut into government seigniorage revenue, and open an express lane for capital flight during a crisis.
The European Central Bank’s Isabel Schnabel made the same point from Seoul this June: growing stablecoin use, she warned, “may further cement the international dominance of the US dollar” at the expense of smaller, weaker currencies.
For Vietnam’s dong, the Indonesian rupiah, the Philippine peso, or any currency that has already lived through informal cash dollarisation driven by inflation and volatility, a frictionless digital version of the same phenomenon is not a hypothetical risk. It’s arguably already underway, just not yet at a scale that shows up in central bank models. None of the region’s regulators have shown any inclination to slow stablecoin adoption down; every incentive, from cheaper remittances to foreign investment optics, points toward encouraging it further.
What this actually means for SEA’s founders and investors
None of this argues against stablecoins. The remittance savings are real, the B2B settlement efficiency is real, and Singapore’s regulatory head start is a genuine regional asset.

However, the industry conversation in Southeast Asia has been almost entirely one-sided — infrastructure triumphalism, without much scrutiny of what happens to a central bank’s toolkit when a meaningful share of a country’s dollar exposure moves onto rails it doesn’t control. Founders building in this space should treat regulatory fragmentation as a permanent design constraint, not a temporary inconvenience.
And investors backing the next StraitsX or MetaComp would do well to ask not just how fast the corridor is growing, but how a central bank in Jakarta, Hanoi or Manila is likely to respond once the flows get big enough to notice.
