SoFi’s $25 Billion Stablecoin Shift Tests Settlement Beneath Card Payments
PYMNTS reported that SoFi Bank and Mastercard are moving SoFi’s $25 billion card program onto stablecoin settlement, testing whether tokenized dollars can improve card and treasury infrastructure without changing checkout behavior.

A $25 billion SoFi card migration is turning stablecoins into settlement plumbing rather than a new checkout habit, PYMNTS reported, as SoFi Bank and Mastercard move the bank’s debit and credit card program onto token-based settlement while keeping the consumer payment experience unchanged.
That arrangement shifts the test for digital assets away from whether shoppers want to pay with crypto.
Consumers can still use cards, merchants do not need to hold SoFiUSD, and Mastercard remains the network linking participants.
The change sits after authorization, where obligations between financial institutions are settled.
SoFi Bank is migrating its entire card program to settlement using SoFiUSD, a U.S. dollar-backed stablecoin issued by the bank, together with Mastercard’s global payments network.
The announcement puts a nationally chartered bank, a card network and a bank-issued token into one payments stack, giving the project a different profile from consumer wallet launches that ask merchants and users to adopt a new front-end payment method.
The same week also brought an infrastructure move from Thredd, which expanded its issuer processing platform to support stablecoin-powered money movement.
Thredd’s first use cases target business card programs backed by stablecoins, international payouts, treasury movement and settlement recorded on-chain.
Together, the moves suggest that stablecoins are being tested first as institutional rails, not as a replacement brand at the point of sale.
That creates a different set of market metrics.
Token supply and market capitalization have dominated crypto market discussions, but settlement infrastructure is more about velocity, liquidity and reconciliation.
A bank-issued stablecoin could maintain a modest outstanding supply while moving repeatedly through card settlement, treasury transfers and cross-border payments.
In that model, the important number is how much money the token moves, not how much sits in circulation at one time.
Mastercard has also framed the opportunity in infrastructure terms.
Chief Financial Officer Ling Hai said on Sept. 10 that stablecoin and digital asset infrastructure can support growth, while the network adds tools that coordinate stablecoin flows and let partners offer wallet features under their own brands.
That positioning keeps the card network in the middle of the flow while adding tokenized settlement beneath it.
The potential upside is faster money movement outside conventional banking hours.
If institutions can move funds economically at 2 a.m. on a Sunday, businesses may reduce prefunding needs and free liquidity that would otherwise be trapped while waiting for traditional settlement windows.
Cross-border payouts and treasury operations are among the areas where that speed could matter.
The trade-off is operational.
Continuous settlement can reduce one working-capital constraint while forcing finance teams, fraud controls and treasury systems to run on a clock that does not stop.
Forecasting and reconciliation processes built around bank-day cycles may need to adapt if tokenized settlement becomes part of mainstream card and treasury infrastructure.
The unresolved question is therefore not whether blockchain can move digital assets.
SoFi’s migration tests whether tokenized dollars can improve the hidden machinery of card settlement without asking consumers, merchants or financial institutions to rebuild the payment experience around them.
