How stablecoin settlement works in cross-border payments
Sending money across a border still means asking a chain of banks to update their ledgers one after another, during their own working hours, in their own time zones. A stablecoin replaces that chain with a single shared ledger that never closes.
This is the second of four Disrupts explainers on the new money rails. It follows a payment from a buyer in one country to a seller in another and shows where the stablecoin fits, what it removes, and what it does not.
What the old route looks like
A company in Manchester paying a supplier in Lagos does not send pounds to Nigeria. Its bank debits the account and sends a message, over Swift, to a correspondent bank that holds accounts for both sides. That bank may pass the instruction to another. Each step is a separate ledger entry, each bank takes a fee and a foreign exchange margin, and each one only works during its own business day. A payment sent on Friday afternoon may not land until Tuesday. Swift's own tracking service, gpi, has cut the average time sharply, but it still cannot guarantee same-day arrival in every corridor, and the fees on emerging-market routes commonly run to several per cent once the FX margin is counted.
The friction is not the message. The message is instant. The friction is that the money itself has to be moved between separate balance sheets that do not trust each other and do not share a clock.
What a stablecoin changes
A stablecoin settlement collapses the chain into three steps: on-ramp, transfer, off-ramp.
On the on-ramp, the payer's provider takes pounds and buys dollar stablecoins, either from an issuer such as Circle or on an exchange. On the transfer, the tokens move from the payer's wallet to the payee's wallet on a public blockchain. That leg is the part that is different: it is a single entry on a single ledger, it is final in seconds, it costs a few cents in network fees on most chains, and it works at three in the morning on a Sunday. On the off-ramp, the payee's provider sells the tokens for naira and pays them into a local bank account or mobile wallet.
The middle leg is what the industry means by settlement. The correspondent banks are gone from that leg because the shared ledger does the job they existed to do: it lets two parties who do not trust each other agree that value has moved. Estimates from providers in the sector put the saving on emerging-market corridors at 50 to 70 per cent against the correspondent route, with most of the saving coming from removing intermediaries and compressing the FX spread rather than from the network fee itself.
Who is building on it
The reason this went from a crypto curiosity to a boardroom topic in the space of about 18 months is that the largest payment companies bought the plumbing. Stripe paid $1.1bn for Bridge in 2024 and now lets merchants in more than 100 countries accept stablecoins, settling to them in local currency if they prefer. Mastercard paid $1.8bn for BVNK to bring stablecoin settlement inside its network. Visa was settling about $4.5bn a year in stablecoins with its acquirers by January 2026, using USDC to square accounts on days the banking system is shut.
Circle, the issuer of USDC, runs the Circle Payments Network, a permissioned layer that lets regulated banks and payment firms settle cross-border payments in USDC with each other while keeping the compliance checks they are used to. Its pitch is a cost of single-digit basis points plus FX, against single-digit per cent on the old route. Alongside it sit a growing set of orchestration providers that do the same job for smaller tickets across several chains and tokens.
Swift, the incumbent, has responded rather than resisted. It has built a blockchain-based shared ledger with Consensys that carries its existing ISO 20022 message format, and in July 2026 said the ledger was ready for early use, with 17 banks from six continents preparing live 24-hour cross-border transactions. The cash leg on that ledger can be a stablecoin, a tokenised bank deposit or a central bank digital currency; Swift is deliberately not choosing.
What the stablecoin does not fix
The on-ramp and the off-ramp are still the hard part, and they are where most of the cost and the risk now sit. Someone has to hold a local bank account, a local licence and a pool of local currency at each end, and to convert at a rate. In corridors where dollar liquidity is thin, the spread on the off-ramp can eat much of the saving on the transfer leg. Providers compete on exactly this: how many countries they can pay out in, how fast, and at what rate.
Compliance does not disappear either. The transfer leg is pseudonymous, but the providers at each end are regulated money businesses and must run the same know-your-customer and sanctions checks as a bank. The Financial Action Task Force's travel rule, which requires sender and recipient details to accompany a transfer, applies to them. The industry's answer is to do the checks at the on-ramp and off-ramp and to treat the chain as the rail in between.
Regulation also sets which tokens can be used where. In the European Economic Area only MiCA-authorised tokens such as USDC and EURC can be offered by regulated platforms since the transitional period closed on 1 July 2026, so a corridor into Europe cannot end in USDT. In the United States the GENIUS Act framework will decide who may issue a dollar token at all once its final rules land, expected by November 2026.
A worked example
Take a UK software company paying a $20,000 contractor invoice in the Philippines on a Friday evening. Through a bank, the payment leaves on Monday morning, passes through a US dollar correspondent, arrives Tuesday or Wednesday, and the contractor receives perhaps $19,400 once wire fees and a two to three per cent FX margin are taken at each end.
Through a stablecoin provider, the company pays pounds on Friday evening, the provider buys $20,000 of USDC at a spread of a few tenths of a per cent, the tokens land in the provider's Philippine partner wallet within a minute, and the partner pays pesos into the contractor's account on Saturday morning at a spread that competition has pushed down to under one per cent in that corridor. The contractor keeps around $19,750 and gets it three working days earlier. The stablecoin did not do the FX; it removed the banks that were charging for the wait.
Where this goes
Stablecoin payment volume outside crypto trading is estimated at around $390bn a year and business-to-business use grew more than sevenfold in 2025, yet stablecoins still carry about 1 per cent of global payment flows. The next stage is not more chains or more tokens. It is the last mile: deeper local liquidity at the off-ramp, a single compliance standard that every provider accepts, and a settlement asset that a bank's own risk committee will hold on its balance sheet overnight. That last point is why banks are building a stablecoin of their own, the tokenised deposit, which is the subject of the next explainer.
