Stablecoins and the Inescapable Role of Banks

Why Banks Remain Central to Stablecoin Scaling
Stablecoins can accelerate the middle leg of an enterprise cross-border payment—moving value between institutions on a blockchain in seconds—but the first and final legs still require fiat currency, domestic payment networks, and regulated compliance systems. Even as stablecoins replace some correspondent-bank and SWIFT messaging, banks remain indispensable for converting local currency into stablecoins and back again.
Legacy Bank Constraints
Large, established banks operate on decades-old technology stacks and interlocking processes across treasury, compliance, risk, legal, and audit functions. Each department holds veto power, making wholesale upgrades to incorporate programmable money slow and costly. This structural inertia hampers rapid deployment of stablecoin rails within traditional institutions.
Emerging Technology-Native Bank Model
Startup Augustus received conditional OCC approval to become a national bank and raised $180 million at a $1 billion valuation. Augustus is building a regulated clearing bank with stablecoin settlement embedded from day one, allowing new products to ship in weeks rather than years. The model shows how a “technology-native” bank can treat instant, programmable settlement as a core element.
Industry Integration and Acquisitions
Major fintech and payments firms are acquiring stablecoin-related infrastructure rather than bypassing banks.
- Mastercard completed its acquisition of BVNK on August 3, paying up to $1.8 billion to merge its fiat network with a platform that processes $30 billion in annualized stablecoin volume across more than 130 countries.
- Stripe purchased stablecoin platform Bridge for $1.1 billion in October 2024, positioning itself as an orchestrator that connects stablecoin flows to legacy banking systems.
- Chime Financial is soliciting proposals to embed stablecoin wallets in its consumer app, and Klarna has launched KlarnaUSD on Stripe’s Tempo blockchain.
Regulatory Landscape and the GENIUS Act
The GENIUS Act, signed in July 2025, imposes bank-grade reserve, disclosure, and licensing standards on stablecoin issuers, with an enforcement cliff on January 18 2027. An EY-Parthenon survey notes that 63 % of corporates intend to rely on traditional banking partners for stablecoin adoption, underscoring compliance as the primary barrier. Singapore’s MAS has proposed a 100 % reserve requirement while prohibiting yield on those reserves; Raj Kamal, CEO of TransFi, supports the rule but argues income from approved reserve assets should be permissible.
Data on Stablecoin Volume vs. Global Payments
- McKinsey and Artemis Analytics estimate annual stablecoin payment volume at roughly $390 billion, about 0.02 % of the $1.9 quadrillion global payment volume.
- Forkast notes B2B stablecoin payments reached a $226 billion run-rate by late 2025, a 733 % year-over-year increase, concentrated among firms with strong banking relationships.
- EY-Parthenon found 13 % of financial institutions and corporations actively use stablecoins, while 80 % of non-users are considering adoption.
Implications for Cross-Border Payments
Stablecoins can replace the “middle leg” of a three-leg payment journey, reducing reliance on correspondent banks and SWIFT messages. The “entry” and “exit” legs still depend on fiat infrastructure, FX capabilities, and local settlement rails. Providers that secure multiple banking relationships and compliant access to domestic systems—such as Brazil’s Pix network, which processed more than 35 trillion reais (about $6.9 trillion) in 2025—gain a competitive advantage and mitigate operational risk.
Future Outlook
A consortium of 21 major financial institutions plans to launch a USD-pegged stablecoin by early 2027, aiming to capture efficiency gains while retaining control over payment endpoints. PYMNTS’ repo-market analogy suggests stablecoin ecosystems will need a mature “dealer” layer to connect fragmented liquidity pools, mirroring the hub-and-spoke structure that underpins daily repo activity.
