For years, stablecoins were a punchline — crypto's embarrassing middle child, too boring for DeFi maximalists and too risky for regulators. Then something shifted. Quietly, almost without announcement, they started moving real money. A lot of it.
The numbers that define the shift
The $27 trillion headline and why it misleads
Stablecoin transaction volume exceeded $27.6 trillion in 2025 — surpassing Visa and Mastercard combined on an annualised basis for the first time. That number is technically accurate and strategically useless. The majority is trading activity, internal wallet shuffling, and automated DeFi transactions that have nothing to do with payments. McKinsey and Artemis Analytics stripped all of that out. What remained was approximately $390 billion in actual stablecoin payments: money moving between real counterparties for real commercial purposes. Still more than double 2024. Still growing at 90% year-on-year. But a very different picture from the headline.
Where the real volume is concentrated
The $390 billion is not evenly distributed. It sits in emerging market B2B flows, remittances, and treasury operations — exactly where stablecoins have the sharpest structural advantage and where incumbent payment rails are weakest. Remittance corridors between the US, Mexico, and the Philippines now see significant stablecoin flow through platforms like Bitso and GCash. B2B treasury management in LatAm and Southeast Asia is increasingly routed via USDC and USDT to sidestep correspondent banking delays of three to five days and fees averaging 6.2%. The infrastructure thesis — stablecoins not as a speculative asset class but as plumbing — has quietly won the argument. The question is no longer whether stablecoins will be used for payments. It is how fast the existing rails get replaced.
Regulation finally caught up
Europe moved first
In the EU, MiCA's stablecoin provisions came into effect mid-2024, creating the first compliant framework for euro-denominated stablecoins at scale. Euro-pegged stablecoins remain a small fraction of total market cap, but MiCA has done something more important than launch a product: it has set the compliance bar that any institution touching European users must clear. The UK's FCA released its own consultation framework in 2025, proposing a slightly more permissive model that allows fintechs — not just banks — to issue stablecoins if they meet authorisation and reserve requirements. That inclusive approach is deliberate. The UK is positioning itself as the regulated-but-competitive alternative to the more restrictive EU model.
The US crossed the threshold
The GENIUS Act established the first federal framework for payment stablecoins, mandating 1:1 reserve backing in liquid assets, redemption rights, and full AML compliance. The effect was immediate — USDC's market cap surged as institutions moved toward the compliant option. Goldman Sachs, JPMorgan, and Bank of America all began evaluating stablecoin issuance shortly after. The window of regulatory ambiguity that held back enterprise deployment has closed. What took years of market development to build in legitimacy was compressed into months by a single piece of legislation.
Who wins, who gets crushed
The obvious casualty
Traditional correspondent banking takes the most direct hit. SWIFT, for all its recent modernisation, still operates on a model that stablecoins structurally undercut on speed, cost, and programmability. The FSB's 2025 assessment confirmed that none of the G20's cross-border payment targets — speed, cost, access, transparency — are on track to be met by the 2027 deadline. Stablecoins are the sharpest available alternative, and their adoption in the corridors where the targets are most missed is accelerating fastest.
The more interesting disruption
The fintech layer faces a threat that is harder to see but more consequential. Neo-banks and payment processors built on top of legacy rails now face genuine technology substitution risk, not just competitive pressure from better UX. The window for experimentation is closing — 2026 is the year of integration or elimination for fintechs that have not made stablecoins a first-class citizen of their stack.
The structural winners
The winners are those moving to become stablecoin-native. Circle's B2B product suite, Stripe's acquisition of Bridge, and PayPal's PYUSD — which jumped from $785 million to $4.8 billion in monthly volume in twelve months — all point in the same direction. The payment layer is collapsing onto programmable money, and incumbents who do not move will find themselves disintermediated by the infrastructure they chose not to build.
The geographic split reveals the real growth engine
Where adoption is fastest — and why
IMF working paper data shows Asia-Pacific leads in absolute terms, but Africa, the Middle East, and Latin America lead relative to GDP — by a significant margin. In Sub-Saharan Africa, stablecoins account for approximately 43% of transaction volume, driven primarily by dollar-denominated inflation hedging rather than speculation. In Latin America, 71% of institutions surveyed use stablecoins for cross-border payments. The Philippines has seen adoption climb to 22–23% of the population, almost entirely driven by inbound remittance flows.
Monetary necessity, not technology enthusiasm
The structural driver in these markets is not technology adoption — it is monetary desperation. In Argentina, Turkey, and Venezuela, stablecoins function as a parallel savings system because the local currency cannot be trusted to hold value. In Nigeria and Kenya, stablecoins solve for the cost and speed failures of correspondent banking on corridors that traditional fintech has never served profitably. These are not pilot programs. They are permanent infrastructure substitutions driven by necessity.
South Asia is the most underpriced growth story
TRM Labs data shows South Asia was the fastest-growing region for stablecoin-driven adoption in the first half of 2025, up 80% year-on-year. India, Pakistan, and Bangladesh are all in the top tier of Chainalysis's Global Adoption Index. The India angle is almost entirely absent from Western coverage: GIFT City is piloting stablecoin corridors targeting remittance costs below 1%, against a current average of 5–7% on the India-US corridor. India receives more in remittances than any country on earth. If stablecoin rails capture even a meaningful fraction of that flow, the volume implications are enormous — and the incumbents on those corridors face structural compression they have not yet priced.
Retail adoption is arriving through the back door
The shift in transfer size
The conventional view is that stablecoin adoption is institutional and B2B. That was accurate twelve months ago. The number of stablecoin transfers under $250 hit a record high in August 2025. Unique wallet addresses grew from 350 million to over 500 million between 2023 and Q3 2025. The average stablecoin P2P transfer on platforms like Sling was $47, against $250 for traditional remittances — a signal that the use case is reaching genuinely small-ticket, everyday payments.
The invisible rail
Visa and Mastercard have now facilitated over $120 billion in stablecoin-related transactions, and both have products that abstract the stablecoin layer entirely — users pay in fiat, the stablecoin rail handles settlement, merchants receive local currency. The user never sees the word stablecoin. This is how mass adoption actually happens. Not through crypto-native interfaces, but through familiar experiences built on top of programmable rails. The fintech implication is direct: the companies best positioned to capture retail stablecoin flows are not the ones building crypto-forward products, but the ones building consumer payment experiences that happen to route through stablecoin infrastructure.
The interoperability problem is the next battleground
A fragmented ecosystem hiding inside headline growth
The IMF has flagged — and the market has not fully priced — the risk of a fragmented stablecoin ecosystem. USDT dominates emerging markets. USDC dominates regulated institutional corridors. EURC is growing fast in Europe following MiCA. Each stablecoin operates on different chains, with different reserve structures, different regulatory frameworks, and limited interoperability across those boundaries. Supply forecasts range from $1.9 trillion to $4 trillion by 2030 — but only if the fragmentation problem is solved. It has not been solved yet.
The white space
Whoever solves interoperability at scale — the ability to move seamlessly between stablecoin denominations, chains, and local fiat rails in a single transaction — captures a market that no incumbent has yet claimed. It is not a technical problem; the technology largely exists. It is a compliance and standardisation problem. Which means it is a regulatory problem. And regulatory problems, for companies with the right relationships and the right architecture, are moats.
SB Finance Research View
The corridor-by-corridor finding
The aggregate headlines miss the most important story. Adoption is not uniform — it is fastest where legacy friction is highest and banking infrastructure weakest. LatAm and Southeast Asia are running three to four years ahead of Western Europe on stablecoin payment penetration. That gap will compress, but it means the playbook already exists. The companies building on it now have a significant head start.
The 47-market analysis
We mapped stablecoin adoption velocity against legacy banking penetration across 47 markets. The correlation is inverse and consistent: the lower the banking penetration, the faster the stablecoin adoption curve. Stablecoins do not compete with good banking infrastructure — they replace the absence of it. The implication for fintech market entry strategy is significant. The markets that look hardest to serve on conventional metrics — thin margins, high compliance cost, volatile local currency — are precisely the markets where stablecoin rails offer the sharpest competitive advantage and the least incumbent resistance.
The monetary statecraft angle
The GENIUS Act's most consequential long-term effect is not the compliance framework it created — it is the Treasury demand it will generate. Stablecoin issuers are required to hold reserves in US Treasuries and cash equivalents. US Treasury Secretary Scott Bessent has projected stablecoin supply reaching $3 trillion by 2030. At that scale, stablecoin issuers collectively become one of the largest holders of US government debt on earth. Tether already holds approximately $100 billion in US Treasuries. Dollar-denominated stablecoins have become an instrument of US monetary statecraft, not just a payments technology. That is a durable structural tailwind that no competitor currency has yet matched — and almost nobody is covering it as such.
The interoperability opportunity
The fragmentation risk is real but it is also an opportunity. The company that builds the compliance infrastructure enabling seamless interoperability between USDT, USDC, EURC, and local fiat rails — in a single transaction, across jurisdictions, with regulatory defensibility — will capture value that is currently left on the table in every cross-border corridor on earth. That product does not fully exist yet. It will be worth considerably more than the market currently assigns to the stablecoin infrastructure category.
Our proprietary finding
We mapped stablecoin adoption velocity against legacy banking penetration across 47 markets. The correlation is inverse and consistent: the lower the banking penetration, the faster the stablecoin adoption curve. This is not accidental. Stablecoins do not compete with good banking infrastructure — they replace the absence of it. The implication for fintech market entry strategy is significant. The markets that look hardest to serve on conventional metrics — thin margins, high compliance cost, volatile local currency — are precisely the markets where stablecoin rails offer the sharpest competitive advantage and the least incumbent resistance.
Bottom line
The infrastructure thesis has won the intellectual argument. The next three years will determine who wins the commercial one. The companies that move from pilot to production in high-friction corridors before the regulatory frameworks fully crystallise will have distribution advantages that are very difficult to replicate later. The window is open. It will not stay open indefinitely.
