Stablecoin Payments: Speed at a Price
TREE NEWS reports: Stablecoins promise near-instant, low-cost cross-border payments, but a recent experiment by the Bank of Italy highlights a significant caveat: the total cost of moving money via stablecoins can be far higher than the blockchain transaction fee alone. In a test of ten international payment routes, sending $200 in stablecoins cost between $0.60 and nearly $18, depending on the corridor. The bulk of that expense came not from the on-chain transfer, but from the fiat on-ramp and off-ramp—the processes of buying the tokens at the origin and cashing them out at the destination.
The On-Ramp and Off-Ramp Burden
The Bank of Italy’s findings underscore a persistent friction in the stablecoin ecosystem: while blockchain settlement is cheap, the surrounding infrastructure—exchanges, custodians, and banking partners—introduces fees, spreads, and delays. For a $200 remittance, a $18 cost represents a 9% fee, far exceeding the 1-2% typically targeted by traditional remittance services. Even the lower end of the range (60 cents) is only competitive when on-chain fees are minimal and the corridor is highly liquid.
This cost structure matters because stablecoins are increasingly touted as a solution for cross-border payments, especially in emerging markets where banking access is limited. However, if the total cost remains high, stablecoins may struggle to displace established players like money transfer operators or mobile money services.
Industry Implications: Where the Money Goes
The experiment suggests that the stablecoin industry’s next battleground is not blockchain scalability but fiat integration. Companies that can streamline the conversion between fiat and stablecoins—through better banking relationships, local payment rails, or regulatory clarity—stand to gain. Several fintechs and crypto-native firms are already working on this: Circle’s partnership with local banks, Ripple’s acquisition of a custody provider, and various startups offering “stablecoin-as-a-service” with built-in on/off-ramps.
Moreover, the disparity across corridors (from 60 cents to $18) indicates that liquidity and competition in local markets play a huge role. Corridors with multiple stablecoin issuers and active exchanges tend to have lower costs, while thinner markets suffer. This mirrors traditional remittance corridors, where costs are highest where competition is weakest.
Regulatory and Market Outlook
Regulators are taking note. The Bank of Italy’s study is part of a broader effort by central banks to understand stablecoins’ role in payments and their potential impact on monetary sovereignty. As frameworks like the EU’s MiCA come into force, clearer rules on reserves, redemption, and licensing could reduce the risk premium embedded in on/off-ramp fees. However, compliance costs may also rise, potentially offsetting some gains.
For now, stablecoin payments are a promising but imperfect tool. They offer speed and transparency, but the cost problem is real and rooted in the traditional financial system that they aim to disrupt. Until the fiat on/off-ramp becomes as seamless and cheap as the blockchain transfer itself, stablecoins will remain a complement—not a replacement—for existing payment methods.
