You can find a supplier in another country, agree a price, sign the contract and send the invoice before lunch. Then you try to pay them, and everything drops to the speed of 1970s banking: cut-off times, a correspondent bank you have never heard of, a fee that only shows up after the money has left, and no straight answer to the one question that matters, which is when the other side can actually spend it.
That gap, between how fast we can agree and how slowly we can settle, is the case for blockchain in finance. Not the whole case for crypto, and not a promise that every problem goes away. Just this one job: moving value across borders and between institutions without a chain of handoffs.
What the slow version costs
Inside one country, payments are mostly fine now. Most large economies have some form of instant transfer. The trouble starts at the border, where every institution on the route keeps its own ledger, runs its own hours and applies its own checks. What is a single instruction for the sender turns into four or five internal steps that nobody outside can see.
The World Bank has been measuring what this costs since 2008. Its Remittance Prices Worldwide dashboard tracks the price of sending $200 across hundreds of country corridors, and the latest headline number (Q3 2025) is 6.36% of the amount sent. So a $200 transfer costs $12.72 on average. Send that home every month and it comes to roughly $150 a year, taken out of money that was already earned and taxed once.
The average hides a very wide spread. In the same report, sending through a bank averaged 14.99%. Digital-only money transfer operators averaged 3.54%. The target the G20 and the UN have set is 3%. So the cheap end of the existing market is already close to the goal and the expensive end is five times over it. Moving money cheaply is not a technology we lack. It just depends enormously on which door you walk in through, and most people walk in through the one they already know.
Businesses lose a different thing: time. Money in transit cannot pay a supplier or make payroll. Somebody in finance spends part of every week chasing remittance advices, matching bank statements to invoices, and explaining to a supplier that yes, the money really did go out on Tuesday. None of that work produces anything.
One record instead of five
Cross-border payments involve so much reconciliation because every institution on the route keeps its own version of what happened. A blockchain replaces those separate records with one that every participant can read and none can quietly edit. Add smart contracts and the record can carry instructions as well: pay this address when that condition is met.
The Bank for International Settlements calls the fully built version of this a "unified ledger", with tokenised central bank money, bank deposits and financial assets on one platform, so that a payment and the thing being paid for settle in the same step. Its 2025 Annual Economic Report treats that as the direction the monetary system should be heading.
Stablecoins are the piece of this that ordinary people can already touch. A stablecoin is a token meant to hold its value against a currency, usually the US dollar, because the issuer keeps reserves against it. That lets you move a dollar balance over a blockchain without pricing your invoice in something that might fall 15% before the client gets round to paying.
The freelancer in Manila invoicing a client in Berlin is the standard example, and it is a fair one. If both sides use services that support the same stablecoin, the transfer clears in seconds, at two in the morning on a Sunday if that happens to be when the client pays, and the freelancer can watch it land. A small importer paying a factory in Vietnam uses the same rails.
But the transfer is the easy part. The freelancer still has to turn USDC into pesos and get it into an account that pays the rent. That last step involves an exchange rate, a fee, a compliance check, and possibly a queue at a cash-out counter. The on-chain leg can cost a fraction of a cent and the full journey can still come out more expensive than a decent digital remittance app. A cheap transaction is not the same thing as a cheap payment. Anyone who has never held a token before also has to get a wallet and learn not to lose it, which is its own barrier.
Payments that follow the contract
Programmability matters most where money and agreements are tangled together. Take a project with three milestones. Today the client pays the first instalment, the freelancer delivers, and then there is a polite email asking when the second one is coming. An escrow contract can hold the full amount from day one and release each instalment when the agreed sign-off lands. Both sides can look at the contract and see exactly what has been funded, what has been paid, and what is still locked.
That fixes the visibility problem. It does not fix the judgment problem. Somebody still has to decide whether milestone two was actually delivered, and the contract needs a dispute path for when the two sides disagree. Code enforces rules. It does not write them, and it cannot tell a good deliverable from a bad one.
The same idea, scaled up, is what the BIS finds interesting for financial markets. If a tokenised bond and the cash paying for it sit on the same ledger, the trade settles as a single step: both legs complete or neither does. That closes the window where one party has paid and the other has not yet delivered, which is a large part of what settlement systems exist to manage in the first place. Our crypto analytics guide covers how to read this kind of on-chain activity once it exists.
This is already in production
For years the honest answer to "who actually uses this?" was "mostly other crypto companies." That is no longer true.
In December 2025, Visa announced that Cross River Bank and Lead Bank had begun settling their Visa obligations in USDC on Solana, seven days a week instead of five. At that point Visa put its annualised stablecoin settlement volume at more than $3.5 billion.
By April 2026 the pilot had grown to nine blockchains, adding Arc, Base, Canton, Polygon and Tempo alongside Ethereum, Solana, Stellar and Avalanche, and Visa reported a $7 billion annualised run rate, up 50% on the previous quarter. A run rate is a pace, not a year's total, and set against Visa's overall volume it is still small. But a card network settling with regulated banks, in stablecoins, on public chains, every day of the week, is not a proof of concept any more. It is plumbing.
Notice that neither example involves a bank being replaced. Both of them are banks. What is changing is the settlement layer underneath them, and that layer is becoming something anyone can build on.
What it does not fix
This is the point where most articles on the subject start waving their hands, so it is worth being specific.
A blockchain cannot tell you whether a borrower will repay. It cannot make an asset worth more than someone is willing to pay for it. It cannot make a bad contract fair; it will enforce an unfair one with perfect precision.
Stablecoins in particular have a trust problem the technology does not solve. The token is only worth a dollar if the issuer really holds a dollar and will hand it back on demand. The BIS report is blunt about this. It argues stablecoins fail its three tests for sound money: on singleness (they do not always trade at par), on elasticity (every new unit has to be pre-funded), and on integrity (bearer instruments on open networks appeal to people who would rather not be identified). It concludes they "cannot be the mainstay of the future monetary system." You do not have to accept that conclusion to take the argument seriously.
Regulators are responding by treating large stablecoins like the payment systems they are turning into. The Bank of England's November 2025 consultation on sterling stablecoins proposes that systemic issuers back their coins with central bank deposits and short-term gilts, guarantee redemption at par, and cap individual holdings at £20,000 per coin. Those are rules you write for money, not for a software project.
And the consumer experience has a long way to go. People should not need to know which network a token lives on, or lie awake wondering whether they sent the right USDC to the wrong chain. They need accounts that are hard to lose, fees they can see before they pay, and a human to call when something goes wrong. A decentralised exchange removes one intermediary from a trade. It does not remove the risk that you were the one who made the mistake.
The bar
International finance should feel boring. A family should know what will arrive before it is sent. A freelancer should know when the money is theirs to spend. A business should be able to check on a supplier payment the way it checks on a parcel, without ringing three banks.
Blockchain is one of the few tools that can plausibly get us there, because it goes after the actual cause of the friction: too many separate records of the same transaction. Whether it succeeds should be judged on totals, not on transaction fees. Less money lost between sender and recipient. Fewer days waiting. Fewer hours reconciling. If those numbers do not move, the technology has not done its job, however elegant the design.
