Stablecoins become plumbing: settlement, regulation, and the dirham

The best infrastructure is boring. Nobody photographs the water main or celebrates the sewer that made the modern city possible; they simply expect the tap to run and the drain to work. Stablecoins are on that same trajectory, and it is the most under-reported story in money. They are moving from the loudest, most-speculated corner of crypto to something quieter and far more important: plumbing. The pipes that value moves through when nobody is watching.

This is FTG Research on how a speculative instrument is becoming settlement infrastructure — the problem it fixes, the evidence it is fixing it, and the reason we hold ourselves to describing it carefully rather than breathlessly.

The problem: the old pipes are narrowing

Start with the thing stablecoins are quietly routing around, because the fix only makes sense once you see the friction. Cross-border payments still move, in large part, through correspondent banking — a chain of banks holding accounts with each other to pass value across borders. That network is retreating. The Bank for International Settlements documented that the number of active correspondent banking relationships fell roughly 20% between 2011 and 2018, and the count of active country-to-country corridors declined about 10%, even as the value and volume of cross-border payments kept climbing. Fewer pipes, more water, higher pressure. The result is what anyone who has sent money across a border knows in their gut: it is slow, it is expensive, it clears in days rather than seconds, and it stops for weekends and holidays. Value gets trapped in intermediary accounts, and the cost of moving it — especially for smaller payments and poorer corridors — stays stubbornly high.

That is the problem. It is structural, it is documented, and it is getting worse, not better.

The evidence stablecoins are becoming the fix

Now the fix, stated with the precision this subject demands. Chainalysis's adjusted metric — its attempt to filter out speculation and internal churn and measure genuine economic activity — put stablecoin "real economic volume" at roughly $28 trillion in 2025, growing at about a 133% compound annual rate since 2023. Two disciplined caveats travel with that number, and we will not drop them: it is one vendor's proprietary methodology, not an industry-agreed figure, and — this matters — "real economic volume" is not the same as "payments." Only a fraction of that total is real-world payment activity; separate analyses put actual payment volume far lower. So the honest reading of the $28 trillion is not "stablecoins are already the world's payment system." It is "an enormous and fast-growing amount of value now settles on these rails," which is exactly what you would expect to see early in the life of a piece of plumbing.

The reason it grows is mechanical, not ideological. A stablecoin transfer settles in seconds, runs 24/7, and crosses a border without threading the narrowing correspondent-banking network. Set that against days-long, business-hours-only, intermediary-laden legacy settlement and the appeal is not a matter of taste. It is a matter of the requirements.

The tell: incumbents are building for it

You can dismiss a trend that only crypto-native companies believe in. It is harder to dismiss one the incumbents adopt against their own instincts. When Mastercard launched "Agent Pay for Machines" in June 2026, letting AI agents transact at machine speed, it chose to settle across cards, bank accounts, and stablecoins. A network that processes a meaningful share of the planet's card volume put stablecoins in the same sentence as its own core product. That is not a press release to humor a partner. It is the requirements doing the talking.

The Gulf wrote the codes and inspection rules

Plumbing needs a code and an inspector, and this is where the Gulf moved earlier and more concretely than most of the world. The UAE central bank issued its Payment Token Services Regulation in June 2024 (effective the following month), creating a supervised regime for fiat-backed stablecoins rather than leaving them to be policed after the fact. Real, bank-issued dirham stablecoins now exist under it — AE Coin arrived in 2024, and in November 2025 the CBUAE approved Zand to issue Zand AED, described by its issuer as the country's first regulated multi-chain AED-backed stablecoin. (We attribute the "first" and the 1:1-backing claims to the issuers, as one should with any reserve assertion that has not been independently audited at the moment of announcement.) Around them sits Dubai's virtual-asset regulator VARA, established under Law No. 4 of 2022, and the central bank's own instant-payments rail, Aani, live since October 2023. A conventional bank, RAKBANK, began offering in-app crypto trading in 2025.

The pattern under all of it is the point: the region is treating regulated stablecoins and instant settlement as payments infrastructure to be supervised, not as a speculative loophole to be chased. And for anyone building on top, supervised infrastructure is the only kind worth building on.

Why "plumbing" is exactly the right word

Plumbing has three properties, and regulated stablecoins are growing into all of them. It is invisible — the user experiences "the payment went through," not "a token settled on a ledger." It is load-bearing — more value depends on it working every month, so reliability comes to matter more than novelty. And it is boring on purpose — the goal is not excitement but that it never, ever fails at the moment you need it.

What it means for the stack

For an operating stack built around markets, money, and intelligence, settlement is not a side quest. It is connective tissue. A venue like Exx1 is designed as a fiat-to-digital gateway precisely so value can cross between traditional and digital rails cleanly. A wallet like PRV Wallet is where regulated settlement meets an actual person. And as intelligence turns agentic, the settlement layer is what lets an agent's decision become a real, final payment rather than a suggestion.

Stablecoins are quietly becoming the settlement layer of the internet. Regulated and supervised, they are infrastructure — not speculation.

The headlines will keep chasing the price, because the price is loud. We will keep watching the pipes, because the pipes are what everything else runs on.

Notes & sources

The $28 trillion figure is Chainalysis's adjusted "real economic volume" metric (2025) and is explicitly not equivalent to payment volume, which independent analyses place far lower; it is one vendor's methodology, cited as such. Correspondent-banking decline figures are from the Bank for International Settlements (2011–2018). UAE regulatory references — the CBUAE Payment Token Services Regulation (2024), Dubai's VARA (Law No. 4 of 2022), Aani (2023), and named AED stablecoins (AE Coin, Zand AED) and bank programs (RAKBANK) — are drawn from primary regulator and issuer publications; issuer "first," "1:1 backing," and reserve claims are attributed to those issuers rather than independently verified here. Mastercard "Agent Pay for Machines" (June 2026) is an announced capability. This piece is research, not investment advice.
