Banks Are Building Stablecoin Guardrails While the Market Builds the Highway

Stablecoins processed $28 trillion in real economic volume in 2025, a figure that excludes speculative trading and reflects actual business payments, cross-border settlements, and treasury operations. That volume is on track to hit $719 trillion by 2035, according to Chainalysis, with a ceiling-case scenario of $1.5 quadrillion if macroeconomic conditions align. The systems enabling that growth are not being built by banks. They are being built by payment networks, infrastructure firms, and capital flowing into tokenized real-world assets — while 93% of banks remain on the sidelines.

Only 7% of 100 banks surveyed by S&P Global in Q1 2026 are developing stablecoin frameworks. None have launched live pilots. Their hesitation stems from structural concerns: the risk of deposit outflows, competition from non-bank entities, and legacy systems that cannot support real-time on-chain settlement without costly overhauls. S&P Global expects large banks to eventually issue tokenized deposits to capture custody and issuance fees, while mid-to-small banks will likely serve as fiat gateways. That path is cautious. It is also slow.

Meanwhile, Stripe acquired Bridge for $1.1 billion. Mastercard bought BVNK. These are not experimental moves. They are infrastructure grabs — purchases of rails that will process trillions in stablecoin volume before most banks complete their first pilot. The GENIUS Act of 2025, designed to protect bank deposits by banning interest on stablecoins, has accelerated the shift. Institutional capital is bypassing stablecoins altogether and flowing into tokenized real-world assets that can legally offer yield. The regulation meant to shield banks is redirecting capital away from the very product that might have forced their evolution.

The demographic clock is compounding the delay. Between 2028 and 2048, $100 trillion is expected to shift from Baby Boomers to crypto-native Millennials and Gen Z. That generation will not default to bank rails when stablecoin infrastructure already exists, scales, and integrates directly into commerce. Point-of-sale adoption alone could add $232 trillion in annual volume — embedded through Stripe and Mastercard, not through bank-built systems.

By the time the first bank pilot goes live, the infrastructure processing the majority of stablecoin volume will already be owned, optimized, and entrenched. The deposit outflow risk banks are modeling may be overshadowed by a deeper threat: irrelevance in a payment layer they did not build and cannot replicate quickly enough.
