Stablecoin card spend grew roughly 105% to 106% year over year, John Timoney, head of strategic partnerships at payments infrastructure platform Rain, said on a panel at Consensus Miami 2026. Cards backed by stablecoins could soon reach double-digit market share in some Latin American markets, Timoney added, even though stablecoin cards still account for less than 1% of global card spend today, per Consensys's Ray Hernandez on the same panel.
Rain recently became a Mastercard Principal Member, letting it issue credit and prepaid cards on Mastercard's network, and the two are exploring on-chain settlement for some program flows using regulated stablecoins. Timoney framed the strategy as additive rather than disruptive: "The card networks over decades have rolled up hundreds of millions of merchants," he said. "Rain explicitly did not want to reinvent the wheel."
Why it matters
The growth rate matters, but the plumbing matters more. Rain says stablecoin settlement lets card programs settle on weekends and holidays, reducing trapped capital by more than 40% in some cases — capital that would otherwise sit idle pre-funding network obligations or borrowing from networks when banking rails are closed. That is the structural reason Mastercard moved to acquire stablecoin infrastructure firm BVNK for up to $1.8 billion and brought Binance, PayPal and Ripple into its blockchain payments push this year.
Market impact
Spend patterns are now indistinguishable from ordinary card activity, Timoney said, with stablecoin card users transacting across typical merchant categories rather than a niche crypto-friendly subset. The Latin American adoption curve is the clearest signal: stablecoin cards are being used across custodial and non-custodial wallets, exchanges and abstracted products, with merchants still receiving fiat in most flows. The friction points that will gate the next leg are on-ramps, abstracted network fees and local payment infrastructure, not consumer demand.
