Stablecoins in Institutional Settlement

An assessment of where stablecoin rails materially change settlement economics, where they do not, and the controls institutions need before routing production volume through them.

24 pages · Published May 7, 2026

Overview

Stablecoin settlement is often discussed as a wholesale replacement for correspondent banking. In practice its advantage is corridor-specific and depends heavily on liquidity at both ends.

This paper looks at the corridors where settlement time and cost improve meaningfully, and at the treasury, custody and reconciliation controls required to operate them.

It also examines the operating model for running stablecoin and bank rails in parallel behind one payout interface.

Key topics
