TL;DR:
Stablecoins are displacing traditional currency corridors in emerging markets, where the cost of sending money can reach up to 8% in combined fees. A report from research firm Delphi Digital argues that blockchain networks present a structural advantage over rigid banking infrastructure.
The analysis notes that 81% of those costs stem from maintaining the underlying banking infrastructure in corridors such as those of Argentina and Nigeria. Unlike traditional systems, stablecoins settle directly against the dollar, eliminate the need for pre-funded liquidity in local currencies, and render both intermediary chains and minimum volume thresholds obsolete.

However, mass adoption faces a major obstacle: off-ramps. Access to bank accounts or interbank rails is a highly limiting barrier whenever value must move between the onchain environment and traditional financial systems. According to Delphi, most of that friction occurs outside the blockchain: while stablecoin minting and burning are resolved in seconds, the bank transfers that feed those systems generate delays due to batch processing cycles.
“Closing that gap is both a regulatory and a technical problem,” the firm noted, also warning that stablecoins will not replace major international currency corridors overnight, but rather those emerging markets where infrastructure costs far exceed exchange rate risk and where traditional banking has abandoned the competition.
Despite the downturn in the crypto market, the total stablecoin supply grew 2.5% in the last month, rising from $308 billion on February 17 to $316 billion as of Tuesday, according to data from DeFiLlama. Delphi identified emerging markets as one of the clearest sources of demand, especially among users who need cheaper access to dollar liquidity.
