Companies attempting to scale stablecoin operations for enterprise use are integrating deeper into the traditional banking system, rather than routing around it. Stripe's $1.1 billion acquisition of Bridge—a company whose primary offering is orchestrating bank relationships—and Citi's launch of dedicated crypto custody services both signal that stablecoin infrastructure cannot displace the banking layer.
An enterprise cross-border payment comprises three legs. The first moves the payer's money in local currency over local rails. The third ensures the payee receives local currency in their account. The middle leg transfers value across borders—historically via correspondent banking through SWIFT messages and multiple intermediary banks, adding days and fees. When both institutions accept a stablecoin, this middle leg settles on-chain in seconds.
Banks remain non-negotiable for the first and third legs. They serve as the essential entry and exit points for fiat, the anchor for compliance, and the provider of local rails in every market a payment touches. Every enterprise payment flow—payroll, vendor invoices, customer revenue, capital distributions—begins and ends in a fiat bank account.
The scale of the payments market underscores this dependency. The cross-border payments market reached $208 trillion in 2025, according to FXC Intelligence. Genuine stablecoin payments ran at approximately $390 billion annualized as of late 2025, according to McKinsey and Artemis data. This represents only 0.02 percent of global payment volume, encompassing both cross-border and domestic flows. By contrast, reports citing annual stablecoin "volume" exceeding $30 trillion largely reflect automated trading, exchange flows and bot activity, not actual payments for goods and services.
For operators attempting to scale stablecoin solutions, the critical constraint is identifying banking infrastructure with sufficient depth for institutional volume. At $50 million in annual payment volume, a single banking relationship, one stablecoin issuer and one compliance layer can manage the load. At $500 million, these arrangements typically prove inadequate. By $10 billion, the success factor shifts from technology quality to the capacity of the banking, foreign exchange and licensing stack to support multiple corridors.
Single-bank dependency represents the most underrated operational risk in crypto payments. Many companies utilizing stablecoin rails rely on just one primary banking partner. When companies encounter a ceiling at mid-scale, it is almost invariably due to an underdeveloped banking layer, not limitations in the crypto layer itself.
For stablecoins to transition from nascent payment rails to core financial infrastructure, regulators must establish clear frameworks that enable banks to bring significant liquidity on-chain, solidifying integration within the broader financial system.
