What are the hidden costs of a SWIFT wire?

The wider picture

The key points from the guide this answer comes from:

1. On 2 November 2026, sending USDC on Base cost under a tenth of a cent in network fees, and USDT on Tron about $2.14. A SWIFT wire often costs $15 to $45 to send, plus intermediary and receiving fees.
2. The network fee is rarely the real cost. A stablecoin payment usually starts and ends in a bank currency, so the conversion at each end, and the spread on it, decides whether it's cheaper.
3. Stablecoins are still a small share of cross-border payments: about $135 billion of a $44.3 trillion market in 2025, or 0.31%, according to Allium and FXC Intelligence. B2B was 0.19%.
4. Stablecoins win when both sides can use them, or when money is going somewhere SWIFT is slow or expensive. Local bank rails often win for payments in EUR, GBP and USD where both sides have local accounts.

The full guide

A stablecoin transfer costs a fraction of a cent on most networks and about $2 for USDT on Tron, against $15 to $45 to send a wire plus deductions. But most payments start and end in bank currencies, so compare the all-in cost, including conversion at each end.
