Why Wise is different
Wise built international banking infrastructure from inception. Their customer base is global by design. So their KYC and underwriting are calibrated for international users, including tightened-country profiles. Mercury and Relay are US chartered banks with US-centric risk models that weight country profile heavily.
The custodial structure
Wise is a money services provider (MSP), not a chartered US bank. Funds are held in custody at partner banks. No direct FDIC insurance. This regulatory structure lets Wise operate with different risk thresholds than chartered banks. Trade-off: less FDIC protection but broader acceptance.

Country profile is tightened tier (Pakistan, Nigeria, Vietnam, etc.). Multi-currency operations needed. International clients paying in EUR/GBP. Bootstrapped solo founder where Mercury's Treasury yield is irrelevant. Wise provides the core banking layer at lower friction.
