# USD → GBP: US Dollar to British Pound settlement on Sera

> A deep, highly-banked corridor where the incumbent spread is already thin, so the opportunity is volume rather than margin. Around $121k was quoted in the last 30 days with nothing filled — the pair simply has no TGBP inventory posted against it yet.

- **Corridor:** USD ↔ GBP (United States ↔ United Kingdom)
- **Status:** Live
- **Bridge stablecoins:** USDC ↔ TGBP
- **Settlement speed:** Sub-second on-chain · ~10s door-to-door

  - ACH (Same-day — Same-day & next-day)
  - Fedwire (Wire)

## Risk notes for liquidity providers

The tightest spreads on the board, so this corridor only works for LPs comfortable earning on turnover. Sterling is a liquid free float with event risk around Bank of England decisions.
