Stablecoin payment rails are delivering measurable advantages over legacy correspondent banking, according to two new industry reports. Data from a Borderless.xyz second-quarter 2026 Benchmark Report, built from nearly three million rate observations across 260 payment corridors in 108 countries, shows stablecoin delivery pricing has slipped below the interbank foreign-exchange rates that large banks typically treat as a floor.
The report's central measure, the parity gap, registered a median negative 3.2 basis points against interbank benchmarks. In practical terms, sending $10,000 through stablecoin corridors cost about 27.2 basis points, or $27.20, at the median. Smaller $500 transfers averaged about 46.2 basis points because fixed fees weigh more heavily, while $1 million transfers averaged about 26.2 basis points. These figures already include provider spreads, rail fees and local taxes where recorded.
Borderless also identified a median routing tax of 23.3 basis points, the extra cost incurred by sticking with a single provider instead of dynamically choosing the cheapest available route. On a $1 million payment, this equates to roughly $2,330. The study said nearly instant on-chain settlement, followed by local payout rails, reduces capital lock-up and operational overhead compared with bank wires that often take one or more business days.
A separate report from Coinbase and The Block Pro Research, titled The Always-On Dollar, found that stablecoins moved more than $400 million per hour on average in organic transfer activity during the third quarter. Over the 12 months ending July 31, about 73% of that activity occurred outside U.S. banking hours. The report highlighted that sending a $200 remittance in USDC on Base is about 86% cheaper than using traditional rails.
Adjusted stablecoin transaction volume has quadrupled since the start of 2023, reaching $891 billion in Q3, and is on track to hit $1.5 trillion in quarterly adjusted volume by the end of 2027 at current growth rates. The report estimates that moving 80% of international transactions onto stablecoin rails could add $155 billion to global annual GDP.
Around 293 million unique blockchain addresses now hold stablecoins, exceeding the combined cardholder base of American Express and Discover and nearly double the mobile banking users of JPMorgan Chase, Bank of America, Wells Fargo and Citi combined. Seven of the ten largest U.S. banks have already tested stablecoins or tokenized deposits for settlement, with the remaining three signaling plans to follow. The report also argues that stablecoins will likely serve as the payment rail for AI agents, citing McKinsey expectations that $3 trillion to $5 trillion of global business-to-consumer commerce will be mediated by AI agents by 2030.
