Visa processed 97% of crypto-linked card transactions in March as monthly volume hit $600 million, driven by stablecoin adoption in Southeast Asia and a structural shift away from speculative spending.
Crypto-linked card spending hit $600 million in March, more than tripling from $187 million a year earlier — a 211% annual increase that has turned what was once a novelty product into a genuine payments channel.
Visa processed $581.8 million of the total, or roughly 97% of all crypto card transactions in the month. That dominance isn't surprising — Visa's infrastructure handles most of the world's point-of-sale traffic regardless of what currency funds the transaction — but the concentration does raise questions about how decentralised these "crypto payments" really are. The answer, for now, is not very: the money moves through the same rails it always has. The difference is what sits in the wallet before the swipe.
Cumulative card volume since the product category emerged has reached $6.5 billion across 21.4 million transactions. Those are small numbers by Visa's standards — the network processed $14.8 trillion in total payment volume in fiscal 2025 — but the growth trajectory suggests something structural rather than speculative. Card spending has increased every month since June 2025, weathering bitcoin's drawdown from $100,000, the war-driven volatility in oil markets, and a broader risk-off rotation that gutted crypto trading volumes.
The stablecoin composition of card spending is shifting. USDT still leads settlement volumes, but USDC has been gaining ground, driven in part by Visa's own stablecoin settlement programme, which brought USDC settlement to US banks in late 2025. Issuers including KAST, Tria, and the Solana-based Pengu Card — which enables USDC and USDT spending at an estimated 150 million merchants globally — have expanded the competitive field beyond early market leaders like Crypto.com and Binance's branded cards.
Geography matters as much as the underlying token. Southeast Asia accounted for approximately 60% of global stablecoin payment volume in the period, a concentration driven by practical need rather than ideological preference. In countries where local currencies are volatile and banking infrastructure is thin, a dollar-denominated card funded by stablecoins offers something credit cards historically couldn't: instant settlement, no foreign exchange markup, and no dependence on a domestic banking relationship. Local card issuance in the region grew 83 times between 2024 and 2025.
The blockchain distribution of card payments reflects fee economics more than loyalty to any particular chain. TRON captured 35% of March's payment volume; BNB Chain accounted for 15%. Ethereum, despite its brand and developer base, remains too expensive for the microtransactions that dominate card spending in emerging markets. A $3 coffee paid for with stablecoins on Ethereum's base layer would cost more in gas fees than the coffee itself — a problem that layer-two networks and alternative chains have solved at the infrastructure level, even if the user never knows which chain processed their tap.
US merchant adoption reached 39% in the period, suggesting domestic demand is absorbing crypto card infrastructure faster than the sector's reliance on Southeast Asian growth might imply. That figure includes both direct crypto payment acceptance and the more common model where a card issuer converts stablecoins to dollars before they reach the merchant — a distinction that matters technically but not commercially. The merchant gets dollars; the customer spends crypto.
The growth trajectory faces headwinds. Regulatory proposals in multiple jurisdictions — including the US Treasury's GENIUS Act AML framework unveiled this week — would impose bank-grade compliance obligations on stablecoin issuers. If those rules apply to card settlement flows, the cost of compliance could compress margins for smaller issuers and consolidate the market around players with existing banking relationships.
DeFi yields have also fallen below traditional savings rates, removing one of the original incentives for holding stablecoins: the ability to earn yield while spending. A Crypto.com card backed by USDC that generates 2% APY is a compelling product; the same card at 0.8% is just a debit card with extra steps.
Still, the March numbers are hard to dismiss. A 211% annual increase across 21.4 million transactions isn't a marketing story — it's a usage pattern. Visa's $581.8 million in monthly crypto card volume is small compared to its broader network, but it was zero four years ago.
