Stablecoin cross border payments stopped being a crypto side project this year. Card networks settle in them, banks are testing them inside SWIFT, and payment providers quietly route supplier payouts through them. For a finance lead at a UK or EU business, the useful question has moved on from "does it work" to two sharper ones: who would you actually be dealing with, and which rulebook decides what they are allowed to do for you?

This piece is the map. If your question is narrower, whether one supplier invoice gets cheaper, we have covered what a stablecoin payment really costs once both ramps are priced in separately, and we will not repeat that arithmetic here.

Who is actually building the rails

Three groups are doing the work, and they are not the ones the crypto press usually profiles.

Card networks

Visa is the clearest signal. Its stablecoin settlement pilot now supports nine blockchains and has reached a 7 billion dollar annualised settlement run rate, up 50 percent in a quarter, with issuers and acquirers settling with the network in tokens. In July it went further and launched the Visa Stablecoin Platform, a single managed environment for banks, fintechs and payment providers to access, store and redeem stablecoins, including wallet infrastructure as a service.

Read what that means for you: you are unlikely to hold a token because Visa uses them. You are likely to benefit, or not, from a settlement layer your card issuer or acquirer has switched on behind the scenes. Visa's own framing is careful here, describing faster settlement, potentially lower costs and better visibility than correspondent banking, subject to network, compliance and off-ramp conditions, and noting that on and off-ramp availability may vary by provider and corridor. When the largest network in the category qualifies its own claims, take the qualification seriously.

Banks and SWIFT

The incumbents are not standing aside. In January, SWIFT completed a pilot settling tokenised bonds using Societe Generale's eURCV, described as the first digital asset meeting the EU's MiCA standards while compatible with SWIFT's systems, with SWIFT acting as the coordination layer over ISO 20022 messaging; the network handles around 50 million messages a day across more than 11,000 institutions.

That is a securities pilot, not your supplier payment. But the direction is plain: the bank rail is absorbing the token rather than being replaced by it. If you want to know how the conventional route works today, here is how a SWIFT cross border payment moves today.

Payment providers

This is where most businesses will actually meet the technology. One US provider reports that B2B stablecoin payments grew 733 percent in 2025, driving most of an estimated 390 billion dollars in annualised stablecoin payment volume. Treat that as a provider's estimate rather than an audited market figure, but the same page makes a point worth keeping: SWIFT says 90 percent of payments reach the beneficiary bank within an hour, yet only 43 percent reach the end customer in that time, because the delay sits in domestic processing on the receiving side. A token can shorten the international leg. It does nothing about the last mile unless the provider has solved that too.

The euro side is smaller and more shaped by regulation than the dollar side. Local currency stablecoins grew from roughly 700 million to nearly 1.2 billion dollars in supply between January 2023 and February 2026, with a sharp break when Tether's EURT was discontinued under MiCA, its circulation falling from over 400 million to about 50 million. In other words, European rules have already deleted a euro token from the market once.

Three models you will actually be offered

Strip away the branding and a business is pitched one of three arrangements.

1. Stablecoins hidden in the provider's back end. You pay in pounds or euros, your supplier receives local currency, and the provider settles between its own entities onchain. You never hold a token. This is the most common model and the least disruptive, and it means your due diligence is about the provider, not about crypto.

2. Token settlement with a fiat final leg. The provider moves value in tokens to a partner in the destination market, which pays out over the local rail. In Europe this is often the cleanest route: settling in stablecoin with an authorised EU crypto-asset service provider or e-money institution and delivering the final leg in euro over SEPA removes the token question from the beneficiary entirely.

3. Direct token acceptance. Your supplier holds a wallet and agrees to be paid in tokens. This is the only model where both companies touch a stablecoin, and the only one that needs the supplier's treasury policy, its auditor and possibly its regulator to agree. It is also the rarest.

The model matters more than the brand name on the pitch deck, because it decides who holds the tokens, and therefore which regulator you should be asking about.

The rulebook: three jurisdictions decide the route

A payment from London to a supplier in Munich, settled in a dollar token, can touch three regulatory regimes. Here is where each stands.

EU: MiCA decides which tokens exist

MiCA is the most settled of the three, and it is strict about the token itself. The same source is clear that only e-money tokens issued by an EU authorised credit institution or e-money institution with a published white paper may be offered to the public in the EU, which as of mid-2026 admits USDC and EURC and excludes USDT from regulated EU venues. Anyone transferring, exchanging or holding tokens for EU clients needs an authorised provider in the chain.

For a German or other EU business, that is a useful filter. A provider that cannot tell you which authorised entity handles the EU leg, and which e-money token it uses, has answered your question.

UK: two regulators and a 2027 start

The UK is building a two-tier regime. The Cryptoassets Regulations 2026 bring a broad range of cryptoasset activities inside the FCA perimeter, with final rules published in June 2026 and the full scope of regulated activities expanding from 25 October 2027. On top of that, the Bank of England will co-regulate any stablecoin HM Treasury recognises as systemic.

The Bank's June policy statement changed two things that matter to businesses. It dropped the proposed per-coin holding limits of 20,000 pounds for individuals and 10 million pounds for businesses, replacing them with a temporary guardrail of 40 billion pounds of issuance per systemic stablecoin, and set backing at a minimum of 30 percent in unremunerated central bank deposits with the rest in short-term UK government debt; it intends to finalise its Code of Practice by end 2026. So a UK company using a future systemic sterling coin would face no cap on how much it holds or sends.

Overseas tokens are handled differently. From 25 October 2027 the FCA regulates stablecoin issuance from a UK establishment in all currencies, captures overseas-issued stablecoins through its admissions regime and financial promotions rules without directly regulating overseas issuance, and for systemic non-sterling coins issued abroad the Bank may defer to the home regulator. Practically, the dollar and euro tokens a UK firm would use are regulated mainly where they are issued.

Keep the timing in perspective. No stablecoin has yet been designated systemic by HM Treasury, and sterling tokens account for roughly 0.5 percent of a stablecoin market of around 315 billion dollars in early 2026. A sterling rail is a 2027 story at the earliest.

US: the GENIUS Act and the dollar tokens

Most stablecoin volume is in dollars, so US rules shape the tokens UK and EU firms will actually meet. Congress passed the GENIUS Act in July 2025, requiring payment stablecoins to be backed by safe assets such as bank deposits, short-term Treasuries and Federal Reserve balances, and prohibiting issuers from directly paying interest. That last point matters for anyone tempted to treat a token balance as a place to park cash: a stablecoin is a payment instrument, not a savings product, in the US and in the UK regime alike.

What this means for a UK or EU business this year

Pull the three strands together and the practical picture is less dramatic than the headlines.

  • •You will mostly meet stablecoins as someone else's plumbing. Networks and providers are adopting them for settlement. Your job is to know when your provider uses them, not to run a wallet.
  • •Ask the regulatory question by leg, not by brand. Which legal entity converts your money, which holds the tokens, which pays out, and under which permission in which country. An EU leg needs an authorised MiCA provider and an e-money token. A UK leg will need FCA authorisation for regulated activities once the regime starts in October 2027.
  • •Match the rail to the corridor. On dense routes like UK to euro area, conventional rails are already fast and cheap; on thin corridors a token rail can be a real improvement. Our sibling piece works through that trade-off in detail.
  • •Watch two dates. The Bank of England's code at the end of 2026, and the FCA's full regime from 25 October 2027. Plans made now should survive both.

The same logic applies to newer use cases. If your interest is software paying on your behalf, we look at stablecoin payments made by AI agents separately.

Where EX FI stands

We state our own position the way we think every provider in this market should state theirs.

EXFI is a trading name of EX Financial Solutions Ltd, company number 17105188, which is not itself authorised or regulated by the FCA and acts as a distributor of payment services provided by Gemba Finance Ltd, authorised and regulated by the FCA as a payment institution under FRN 804853. EXFI accounts are payment accounts, not bank accounts; they are not covered by the FSCS, and funds are safeguarded in segregated accounts in accordance with the Payment Services Regulations 2017. Regulated payment services are provided by Gemba Finance Limited (FCA FRN 804853), UK customers only. If the difference matters to you, read our explainer on safeguarding compared with FSCS protection.

What we offer today is the conventional rail, priced in the open: balances in 16 or more currencies with dedicated IBANs where applicable, SWIFT, SEPA, Faster Payments, BACS and CHAPS, SEPA and UK Faster Payments at 0.99 GBP, international SWIFT at 26.40 GBP, free internal transfers, and FX at 0.70 percent on major pairs and 0.90 percent on minors. That is the baseline any stablecoin route should be measured against.

Stablecoin settlement is on our roadmap as an announced item. It is not live, and we will not describe it as if it were.

FAQ

Which stablecoins can a business use for payments in the EU? Under MiCA, only e-money tokens issued by an EU authorised credit institution or e-money institution with a published white paper can be offered to the public. As of mid-2026 that admits USDC and EURC and excludes USDT from regulated EU venues, and any provider handling the tokens for EU clients must be authorised.

Is there a sterling stablecoin a UK business can use for cross-border payments today? Not at meaningful scale. Sterling tokens are a small fraction of the market, no stablecoin has been designated systemic by HM Treasury, and the Bank of England intends to finalise its rules for systemic issuers by the end of 2026.

Will the Bank of England limit how much stablecoin a business can hold? No longer, on current policy. The proposed 10 million pound business holding limit was dropped in June 2026 in favour of a temporary cap on total issuance of each systemic coin, with no limits on the size, frequency or type of transactions.

Is SWIFT being replaced by stablecoins? The evidence points the other way. SWIFT has piloted settlement with a MiCA compliant euro token while acting as the coordination layer between blockchains and existing bank infrastructure, which suggests coexistence rather than replacement.
