Stablecoins Won't Scale Without Banks

Stablecoins were supposed to route around the banking system. Instead, the companies scaling them are building deeper into it than anyone predicted.

Stripe paid $1.1 billion for Bridge , whose core product is orchestrating banks. Citi is launching crypto custody . Standard Chartered is testing stablecoin settlement in Singapore. One by one, the operators moving institutional volume keep landing on the same architecture.

An enterprise cross-border payment has three legs. The payer's money moves in local currency over local rails—a Brazilian importer paying in BRL via Pix. The payee receives local currency on their end—the supplier collecting dollars in their account.

Between them sits the middle leg: getting value across the border from one institution to the other. That leg used to run through correspondent banking, SWIFT messages hopping between intermediary banks, each holding accounts with the next, each adding a day and a fee. When both institutions accept a stablecoin, that leg settles on-chain in seconds. Banks still own the other two.

That is the division of labor. Stablecoins settle the middle leg. Every flow still begins and ends in fiat, and that is where banks are non-negotiable: the entry point, the compliance anchor, and the local rails in every market a payment touches. The companies scaling on stablecoin rails built into the banking system, corridor by corridor.

Every enterprise payment flow begins in a bank account. Payroll, vendor invoices, customer revenue, and capital distributions live in fiat, they move through regulated financial infrastructure, and the companies sending and receiving them keep that infrastructure regardless of what a payment provider prefers.

The scale of the gap makes the point concrete. The cross-border payments market reached $208 trillion in 2025, according to FXC Intelligence. Genuine stablecoin payments ran at roughly $390 billion annualized as of late 2025, per McKinsey and Artemis, which works out to about 0.02% of global payment volume across both cross-border and domestic flows. The headline figures of $30 trillion or more in annual stablecoin "volume" mostly reflect bots, exchange flows, and automated trading rather than payments. A hedge fund treasury desk, an enterprise running payroll across thirty countries, and an exchange settling institutional withdrawals all begin in fiat.

The question these operators ask is which banking infrastructure connects reliably to which settlement rails, and who built it with enough depth to hold at institutional volume. Most stablecoin companies struggle to answer.
