Why Stablecoins Are Eating Real-World Payments - Part 1

ACX ·

In 2025, stablecoins settled roughly $33 trillion in on-chain volume, more than the $25.5 trillion Visa and Mastercard processed combined. On a stricter, payments-adjusted basis the figure was about $10.9 trillion , approaching Visa's annual payments volume. The total stablecoin supply sits above $300 billion as of mid-2026, and the growth is increasingly coming from people spending and sending dollars, not just trading them. Demand concentrates where the dollar is scarce and slow: a typical cross-border remittance still costs 6.36% through legacy rails, while stablecoin corridors routinely clear at 1.5–2.5% in under a minute. The GENIUS Act , signed into U.S. law on July 18, 2025, gave payment stablecoins a federal framework with 100% reserve and monthly disclosure rules, which pulled banks and merchants off the sidelines. Across ( bridge stablecoins with Across ) moves native stablecoins like USDC and USDT0 across 20+ chains in ~2 seconds, the kind of plumbing Part 2 covers. Stablecoins started as a place to park dollars between trades. By 2025 they had quietly become one of the largest money-movement systems on earth: roughly $33 trillion in on-chain settlement volume for the year, against the $25.5 trillion that Visa and Mastercard moved together. Even the conservative, payments-adjusted figure that strips out bot traffic and internal transfers, about $10.9 trillion by Bessemer's accounting, lands close to Visa's annual payments volume. A product category that barely existed a decade ago now settles money at the scale of the card networks. This post is about the demand side of that shift: why people and businesses are actually choosing to pay with stablecoins. The rails underneath are Part 2. A stablecoin is a dollar that moves at internet speed and settles with finality. For a large and growing slice of the world, that beats the dollar their bank offers. For most of crypto's history the assumption was that stablecoins existed to grease exchanges. That story is now too small. The fastest real-world stablecoin adoption is happening in places where holding dollars is hard, expensive, or quietly discouraged, and where the local currency loses value faster than a savings account can replace it. In high-inflation economies, a stablecoin balance on a phone is the most accessible synthetic dollar account a person can open. No correspondent bank, no minimum balance, no branch visit, no waiting on a wire that clears in three business days if it clears at all. Someone in Buenos Aires or Lagos can receive a payment in USDT or USDC, hold it as a dollar, and spend or convert it on their own schedule. The dollar has always been the world's reserve currency; stablecoins are the first version of it that an ordinary person outside the U.S. banking system can actually custody. What people want is the dollar. Stablecoins are the cheapest delivery mechanism that has ever existed for it. Demand is pulling the asset in; nobody had to push the technology. Card networks feel instant to a shopper, but settlement behind them is slow and the economics are brutal at the edges. Interchange runs 1.5% to 3.5% on a card transaction, chargebacks haunt merchants for months, and a cross-border card payment layers on FX spread and correspondent fees. A wire is worse: a flat charge that stings on small amounts, cutoff windows, and a settlement clock measured in days across borders. A stablecoin transfer settles in seconds, costs a fraction of a cent to a few cents depending on the chain, and clears with the same finality at midnight on a Sunday as it does at noon on a Tuesday. There is no batch window and no business-day calendar. For a merchant, that turns a multi-day receivables cycle into same-block cash. For a treasury team moving money between entities or paying suppliers abroad, it removes the float that legacy banking quietly profits from. The contrast is sharpest in remittances, which is exactly where the adoption curve is steepest. The World Bank pegged the global average cost of sending a remittance at 6.36% in the third quarter of 2025, and bank-originated transfers averaged a punishing 14.99% . Stablecoin corridors, by comparison, routinely clear at 1.5% to 2.5% all-in and settle in under a minute. For a worker sending a few hundred dollars home every month, the difference between a 6% haircut and a 2% one is real money, and the people sending it have noticed faster than any regulator or bank did. Consumer demand for dollar access explains the emerging-market story. Business demand explains why the volume is institutional-sized. Payment processors now offer stablecoin settlement as a line item, letting a merchant accept a payment and receive a dollar-pegged balance without touching the card networks' fee stack or chargeback risk. Cross-border B2B payments, historically the slowest and most expensive corner of finance, are an obvious fit: a supplier in one country can be paid in minutes rather than waiting on a correspondent chain that touches three intermediaries and skims a fee at each hop. The signal worth watching is that average stablecoin transaction sizes have been climbing, which is what you would expect when payrolls, supplier invoices, and treasury transfers move on-chain rather than retail tips. Enterprises do not move size onto rails they distrust; they move it onto rails that are cheaper and final. For years the standard objection to stablecoin payments was legal uncertainty, and it was a fair objection. That changed in 2025. The GENIUS Act was signed into U.S. law on July 18, 2025, establishing the first federal framework for payment stablecoins: a chartering regime for issuers, a requirement that reserves be held 100% in cash and short-term Treasuries, and mandatory monthly public disclosure of reserve composition. A bank deciding whether to settle in stablecoins now has a rulebook instead of a guessing game, and a merchant's compliance team has something to point at. Cautious, balance-sheet-heavy institutions move the largest volumes, and they needed exactly this kind of cover before committing. The framework did not create demand. It removed the last reason for the biggest players to keep ignoring it. The clearest evidence that stablecoin payments have become a category of their own is that purpose-built infrastructure is being constructed around it. Plasma, a stablecoin-native Layer 1 that launched its mainnet in September 2025, ships a protocol-level paymaster that sponsors gas for verified USDT transfers, so a user can send dollars without holding the chain's native token at all, and lets fees be paid in stablecoins rather than a volatile gas asset. When a blockchain's headline feature is zero-fee dollar transfers, it has stopped being general-purpose. It is a payments network with a dollar as its base unit. Builders do not redesign an entire chain around an asset class unless the demand is already there to catch. For anyone the traditional banking system serves slowly or not at all, which is most of the planet, stablecoins are becoming the default way to hold and move a dollar. That leaves the question this post set aside. Once everyone is paying in dollars across dozens of chains and a dozen issuers, how does the value get from where it sits to where it's needed? That is the infrastructure layer, and it's the subject of Part 2.

AI 시장 분석

Stablecoins are rapidly expanding their share in the real-economy payment market, emerging as a viable alternative to the traditional financial system. Their technical advantages, such as reduced cross-border remittance costs and 24/7 instant settlement, are replacing the inefficiencies of legacy payment networks. Investors should focus on the growth potential of blockchain ecosystems as stablecoin penetration into payment infrastructure increases.

DYAX 전담 분석

Stablecoins are evolving beyond mere crypto trading tools into practical payment instruments. By streamlining cross-border transactions, they bypass the slow and expensive correspondent banking network. As infrastructure providers integrate these assets, the resulting liquidity and speed improve financial inclusion and transaction efficiency globally.

Institutional adoption will be the key catalyst for mass scaling. As regulatory frameworks become clearer, the trust gap between stablecoins and traditional fiat will narrow, positioning them as a core component of the future global financial architecture.
