Regulatory bottleneck for stablecoin rails
Stablecoins and fintech infrastructure
The bottleneck is policy translation, not bank demand. Banks already know they want the faster settlement, lower cost, and broader reach of stablecoin rails for cross border payments, but they need clear rules on what counts as a normal payments activity, what controls they must run, and where they can touch the stack. That is why infrastructure firms are asking banks first for access to local payment rails and compliance harmonization, not for speculative crypto exposure.

Layer 2 describes the bank role very narrowly. Banks do not need to become exchanges or wallet providers. They need to provide local bank accounts, payment rails, and compliance coverage so a stablecoin transfer can begin or end in the domestic banking system.

Comparable operators describe the same pattern. Reap says the hard part is fitting money movement products inside each market's regulatory framework, and Kapital says permits matter because trust and legal authority determine whether stablecoin payments can move from pilot to everyday business use.

The external rulebook has started to move. In January 2023, US banking agencies warned banks about crypto sector risks. In March 2025, the OCC reaffirmed that certain custody, stablecoin reserve, and payment activities are permissible for national banks, which shows how much bank participation depends on regulator signals.
Over the next few years, the winners are likely to be the firms that make stablecoin payments look like ordinary bank payments. As rules harden and banks get comfortable offering rail access, the market should shift from specialist crypto partnerships to standard bank integrated payment workflows, which is when cross border stablecoin infrastructure starts to scale like mainstream fintech.
