The case for stablecoins as a lower-cost remittance rail has a serious institutional challenge. Researchers at the Bank of Italy found no consistent cost advantage for stablecoin-based transfers, concluding that fiat conversion costs and payment infrastructure, not blockchain fees, account for most of the variation in both cost and settlement time.
What the Bank of Italy found
The finding cuts at a foundational assumption. Advocates have long pointed to blockchain fee structures as the mechanism that would make stablecoin remittances structurally cheaper than the correspondent banking routes they aim to replace. The Bank of Italy's researchers did not find that to hold. Fiat conversion and the surrounding payment infrastructure drove most of the cost and timing differences between stablecoin remittance options.
That distinction matters. Blockchain fees are programmable and, in principle, compressible. Off-chain costs tied to fiat on-ramps and off-ramps are not subject to the same logic. They do not disappear because the middle of the transaction runs on a distributed ledger.
The read-through for the stablecoin remittance case
The argument that stablecoins could structurally undercut traditional remittance channels has rested on blockchain fees as the key variable. Strip that variable out as a primary driver, and the advantage is harder to pin down. If fiat conversion costs and off-chain infrastructure do the heavy lifting on price, then a stablecoin remittance product competes on those dimensions alone, not on the ledger underneath it. That is a different and narrower thesis.
The counterargument
The counterargument is real. The Bank of Italy's findings capture current infrastructure, which remains fragmented and expensive at the fiat conversion layer. If competition among on-ramp and off-ramp providers intensifies and those costs fall, the programmable cost structure of blockchains could become the decisive margin. The research is a snapshot of a market that has not yet reached scale, and the conclusion may shift as distribution matures.
On balance
On balance, the Bank of Italy has done something specific: it has separated the blockchain cost from the infrastructure cost and found the latter to be the dominant variable. The stablecoin remittance case is not closed, but it now requires a more precise argument. The line to watch is not the blockchain fee. It is the cost of converting fiat at each end of the corridor.
