Banks shift to stablecoin payment rails, signaling structural change
In brief
- Banks replace Bitcoin with stablecoin rails for faster, cheaper global payments
- Coinbase and Checkout.com enable USDC and USDT acceptance for 1,000+ enterprise merchants
- Citi projects stablecoin market could reach $4 trillion by 2030
Coinbase builds the infrastructure
Coinbase has built its Stablecoin Payments platform around this exact insight. The service lets merchants and payment service providers accept tokens like USDC while settling in fiat. The strategy gained momentum in June 2026 when Coinbase partnered with Checkout.com, enabling USDC and USDT acceptance for over 1,000 enterprise merchants.
Regulatory tailwinds have accelerated the trend. In April 2026, Coinbase received approval for a conditional OCC trust bank charter, giving its stablecoin operations a stronger regulatory footing. That approval came months after Coinbase CEO Brian Armstrong announced partnerships with major US banks in December 2025 to explore stablecoin and crypto pilots.
The broader industry is moving in lockstep. In July 2026, the Open Standard consortium launched Open USD, backed by more than 140 companies including BNY, Visa, and Coinbase. This isn't fringe experimentation—it's institutional consensus.
Why banks want stablecoins
Banks want faster cross-border payments. They want to reduce foreign exchange costs. They want to cut chargeback expenses. Stablecoins deliver on all three fronts while operating around the clock on a global scale.
Cross-border B2B payments that currently take days and involve multiple intermediaries can settle in minutes. That speed advantage compounds across thousands of transactions per day. For enterprises managing global supply chains, it's not a nice-to-have—it's a competitive necessity.
Market size and revenue outlook
Market projections underline the scale of opportunity. Citi has projected the stablecoin market could reach $4 trillion by 2030. Coinbase's own estimates suggest $1.2 trillion by 2028. Even the more conservative figure represents a massive addressable market for infrastructure providers.
For Coinbase, this matters beyond headline growth. Payment infrastructure revenue, built on steady transaction volumes from enterprise merchants, offers something closer to predictable cash flows than traditional exchange trading revenue. That durability is what institutional investors want to see.
