Bank of Italy Study Shows Fiat On-Ramps Destroy Stablecoin Fee Advantage
A central bank study reveals that USD Coin is not systematically cheaper than traditional remittance methods due to heavy banking friction. While actual on-chain transfers cost just 0.4%, fiat on-ramps and credit card surcharges push total costs up to 9%. The real bottleneck for global crypto settlement remains anchored in legacy finance.
Bank of Italy researchers tested USDC transfers across ten real-world payment corridors and discovered that on-chain rails are not an instant cure for high remittance fees. Total transfer costs ranged from 0.3% to almost 9%, proving that legacy banking gateways still strangle crypto's cost efficiency.
The friction isn't on the blockchain, which averaged a minuscule 0.4% transfer cost across tested routes. Severe surcharges from credit card funding and exchange conversion fees devoured the savings, with card surcharges alone slapping a 3.8% penalty on UAE transactions.
Settlement speed also tied directly to local fiat infrastructure rather than blockchain capacity. In regions with instant payment rails like Brazil's Pix network, settlement cleared rapidly, but slower markets dragged out execution times to two business days, matching standard bank wires.
Stablecoins still beat traditional bank benchmarks in most tested corridors, but they showed no clear edge over fintech operators like Wise. Until friction at the fiat boundaries dissolves, stablecoin payment growth remains tethered to legacy banking infrastructure.
