Financial Firms and Networks Integrate Stablecoins Into Global Payment Infrastructure

Financial firms and payments networks are exploring ways to make international transfers faster and easier, through both familiar bank-linked payment systems and stablecoins. Swift is working with banks and payment providers to extend domestic services such as Bizum, PayID and Pix across borders, letting consumers use aliases like phone numbers and email addresses instead of account details. Separately, Volante and Circle are integrating USDC workflows into existing bank payment infrastructure so financial institutions can test stablecoin settlement alongside traditional payment rails and controls. Speakers at a Seoul conference said stablecoins may gain traction first in emerging markets and remittances, where weaker banking connections can make conventional cross-border transfers slow and costly; one business executive also described using stablecoins alongside SWIFT transfers for global fund management. A related challenge is uneven stablecoin liquidity: South Korean exchanges record far less trading than major overseas platforms, which use stablecoins broadly across trading, rewards and other services.
Swift said its consumer-payments framework, launched in June, involves more than 100 banks; it also reported that 75% of payments over Swift reach the receiving bank within 10 minutes, often within seconds.
Volante and Circle said banks will be able to assess specific USDC workflows within existing payment infrastructure, including minting and redemption, beneficiary-wallet registration, funding, notifications and wallet-to-wallet payments.
At the Seoul conference, Sphere Labs CEO Arnold Lee said stablecoins may add relatively little in the U.S. and Europe, where banking networks are well connected, but could bring meaningful efficiency gains where correspondent banking relationships are not established.
The South Korean exchange liquidity gap was especially stark for some tokens: USD1’s 24-hour volume on Binance was about 12,400 times its Upbit volume. The article also reported that Coinbase offered a 3.60% annual USDC reward, while Kraken offered 1.75% to 4.50%.
