Stablecoins mask remittance costs behind fast blockchain transfers
In brief
- Bank of Italy researchers tested $200 USDC transfers across Italy and five countries in July paper
- Token conversion to local currency requires banking step taking up to one day despite blockchain confirmation in seconds
- Exchange-rate margins and conversion fees often exceed blockchain transfer costs
The hidden cost structure
Bank of Italy researchers examined $200 USDC transfers across routes connecting Italy with five countries in a paper published in July. The findings expose a gap between what looks cheap and what actually costs money. An inexpensive transfer between digital addresses can therefore be surrounded by more expensive transactions.
The research tested real-world scenarios. USDC transactions were conducted in March 2026; Wise simulations were conducted on April 14. The cheaper route switched with the direction of the payment, meaning no single method dominates all corridors.
Where the friction lives
Recipients face a choice that blockchain speed doesn't solve. Recipients can also keep them, retaining dollar exposure until they want to convert the money into the currency used at home. But waiting costs time, and converting costs money.
Tokens may appear in a wallet within seconds, while conversion or withdrawal requires a banking step that takes a day. During that day, exchange rates move. Services can advertise low transfer fees while supplying fewer reais for each euro than a competitor.
The World Bank's approach to measuring remittance costs already accounts for this. The World Bank's remittance-price work also includes exchange-rate margins in the cost of sending money. Stablecoins haven't changed the economics of currency conversion—they've just hidden it behind a fast blockchain confirmation.
