Two American banks have started paying the card network in stablecoins

the fact
The world’s largest card network has extended to the United States the program that lets banks settle what they owe it in stablecoins instead of by wire. Two institutions have started, and the program is already worth $3.5 billion a year.

At the end of November 2025 the network’s stablecoin settlement program was worth $3.5 billion on an annual basis. On December 17 Bitcoin closed at $86,243, −1.8% against the previous day.

What changes behind the counter

Paying by card takes you two seconds. The settlement between your bank and the network takes days, and it runs on wire transfers that stop at weekends and on holidays. The program extended to the United States replaces exactly that step: the banks settle what they owe the network in stablecoins, on the public chain.

For you, the person paying, nothing changes, and that’s the beauty of it. What changes is the dead time in between. Settlement happens every day instead of only on business days, the money moves in a few minutes, and nothing stops between Friday and Monday anymore. At the end of November the program was worth $3.5 billion a year.

The rules explain it better than the enthusiasm does. In the United States the federal stablecoin law was signed in July, and with it went the uncertainty that had kept the banks on the sidelines. The stablecoin market has passed $300 billion, and at that point a bank stops asking whether it’s allowed and starts asking whether it pays.

Why that chain, and not another

The settlement runs on Solana, and the reason is very practical: it costs little per transaction and confirms fast. Those are the only two things that matter when you have to move money between institutions many times a day. It’s the choice an operations director would make when comparing two quotes, with no faith in any chain involved.

In the same weeks a big investment bank tokenized debt on the same chain, and an American asset manager launched a liquidity fund on it. When three different institutions pick the same infrastructure for three different uses, that infrastructure has stopped being a technology bet.

The network also announced that it will be among the first validators of the chain the stablecoin issuer is building for itself. To me that’s the most interesting step: the company that processes the payments starts running a piece of the infrastructure as well as using it.

And meanwhile the rest of the world gets ready

In Japan two financial groups have signed up to develop a yen stablecoin built so it doesn’t fall under the one-million-yen limit on domestic transfers. In other words, it’s designed for settlement between institutions more than for buying a coffee. Issuance and redemption stay with a bank trust company, and the launch is planned for spring 2026.

The project is part of a program run by the Japanese regulator, which has already approved a joint trial by the country’s three largest banks. The chairman of the group leading the initiative called the shift to a token economy “an irreversible social trend”, which is the kind of line you use once the decision has already been made.

In Hong Kong, meanwhile, the territory’s largest licensed exchange listed on the stock market, raising $206 million, with the retail tranche subscribed 393 times over. On its first day of trading it opened higher, reached five percent up and closed two and a half percent down. Enthusiasm at the raise, coolness on the secondary market, all on the same day.

The first day of trading of Hong Kong’s largest licensed exchange: opening at plus 0.3 percent, an intraday high at plus 5, a close at minus 2.5.

What the price was doing in the meantime

Bitcoin, through all of this, closed at $86,243 against $87,863 the day before, down 1.8 percent. On the chart, the day payments started moving onto a different infrastructure looks like any other day.

On the macro side, the American employment figures had come out, with unemployment at 4.6 percent and expectations of a rate cut shifting accordingly. That’s what moves the price in the short term. The infrastructure news moves something else, on timescales the daily chart doesn’t pick up.

On days like this the useful thing is to keep the two apart. The price responds to rates, leverage and mood; the infrastructure responds to rules and costs. Mix them up and you end up explaining a two percent move with a banking partnership that had nothing to do with it.

put bluntly
on the day the banks started settling in stablecoins, the price fell two percent: they’re two different clocks

Put bluntly: on the day the American banks started settling in stablecoins, bitcoin’s price did minus two, because they’re two different clocks and only one of them makes news every day.
