Stablecoins used to live inside crypto trading apps. Traders held them to move between Bitcoin and Ethereum without touching a bank. That role is changing. Stablecoins now sit inside the payment stack itself. Visa, Mastercard, Stripe, and PayPal all run stablecoin settlement in some form. Banks are testing tokenized deposits alongside them. This guide explains what stablecoins are, how they move money, and why payment companies care.
What Is a Stablecoin?
A stablecoin is a digital token designed to hold a fixed value, usually one US dollar. Most stablecoins reach that fixed value by holding cash and short-term government debt in reserve, one dollar in reserve for every token issued. USDT and USDC are the two largest examples. When a stablecoin is fully backed and redeemable, one token can be exchanged for one dollar at any time.
That fixed value is the whole point. Bitcoin can swing ten percent in a day. A stablecoin is built not to. That stability is what makes it usable for payments rather than speculation.
Why Payment Companies Are Adopting Stablecoins
Card networks and payment processors are not adopting stablecoins because customers are demanding to pay in crypto at checkout. Direct merchant acceptance of stablecoins remains limited. The interest is on the settlement side.
Mastercard has stablecoin settlement live for issuers and acquirers. Visa’s stablecoin settlement pilot now spans nine blockchains. Stripe acquired stablecoin infrastructure firm Bridge in 2024. In 2026, Visa, Mastercard, Stripe, and Coinbase were reported to be backing a joint stablecoin platform called Open USD, with more than 140 banks and fintechs involved. The consumer experience stays the same, a normal card swipe or app payment, while the money moves as a stablecoin behind the scenes.
How Stablecoin Settlement Differs From Card Payments
A card payment usually clears in seconds but settles days later. The merchant sees a pending transaction while banks and card networks reconcile balances behind the scenes, often through multiple intermediaries. That process runs on batch cycles and business hours.
A stablecoin transaction settles on a blockchain. Once confirmed, the transfer is final within minutes, at any hour, on any day. There is no batch cycle and no waiting for a clearing window. For issuers and acquirers, this shortens the time money is tied up between transaction and settlement, which is why the interest has centered on back-end settlement rather than the checkout experience.
Cross-Border Payment Use Cases
Cross-border payments are where stablecoins show the clearest advantage. A traditional international transfer can pass through several correspondent banks, each adding fees and delay. A stablecoin transfer moves directly between wallets on a blockchain, regardless of time zone or banking hours. PayPal’s crypto payment tools already convert wallet balances into merchant payouts with this goal in mind, aimed at cutting cross-border fees.
Can Stablecoins Replace Correspondent Banking?
Not entirely, and not soon. Correspondent banking still handles the compliance checks, currency conversion, and regulatory reporting that cross-border payments require. Stablecoins can move value faster, but the surrounding infrastructure, fraud checks, sanctions screening, local currency conversion, still runs through regulated institutions. Most industry analysts expect stablecoins to work alongside correspondent banking, speeding up the transfer layer without replacing the compliance layer.
Regulatory Developments
In the United States, the GENIUS Act, signed in 2025, created the first federal licensing framework for payment stablecoins. It requires issuers to hold full reserves and sets rules for redemption and oversight. Final implementing rules are still being finalized by regulators including the OCC, FDIC, and Treasury, with the framework expected to take full effect in early 2027. In the European Union, MiCA already sets reserve and licensing requirements for stablecoin issuers operating in the bloc. Together, these frameworks are what has allowed banks and payment networks to move from experimentation to production use.
Common Misconceptions
“Stablecoins are just crypto speculation.” Most stablecoin volume today is institutional settlement and payments infrastructure, not trading.
“Stablecoins are anonymous.” Issuers hold reserve and redemption data, and regulated platforms apply the same anti-money-laundering checks as banks.
“Stablecoins will replace bank accounts.” They are a settlement tool. Regulated banks and payment institutions still hold the reserves and manage compliance behind them.
Stablecoins are becoming payment infrastructure, not a replacement for the banking system around them. Understanding that distinction is the starting point for following how they develop next.
