Stablecoin Payments Hit $482bn This Year Even as Supply Stops Growing

Payments made with stablecoins, meaning dollar-pegged tokens used to move value rather than to speculate, reached $482bn so far this year, up 45 percent, according to figures from the analytics firm Allium reported by CoinDesk. Crypto Briefing put the same number against the same drivers: card spending, and the arrival of Visa, Mastercard and Stripe as connective tissue between token balances and ordinary bank money.

The more interesting half of the finding is the half that did not grow. CoinDesk reports that the outstanding supply of stablecoins has stalled even as payment volume climbed. Those two numbers measure different things. Supply is a stock, the quantity of tokens in existence at a moment. Payment volume is a flow, the value that passes through them over a period. A stock can sit still while the flow across it accelerates, and that is what the data describes: the same dollars changing hands more often.

Velocity, not issuance

For most of the stablecoin era the headline number was supply, because issuance was the proxy for adoption. More tokens meant more people holding digital dollars. A flat supply with rising payment volume breaks that proxy. It suggests the growth is now happening in usage rather than in balances, which is what you would expect if the marginal stablecoin transaction has shifted from a trading desk parking collateral to a business settling an invoice or a cardholder buying something.

The named intermediaries matter here. Visa, Mastercard and Stripe are not issuing anything. They are plumbing: the layer that converts a token balance into an authorisation a merchant terminal understands. When that layer exists, a stablecoin balance can be spent without ever being redeemed into a bank account first, and each dollar of balance supports more transactions in a year.

Two numbers to keep apart

The practical consequence for anyone reading stablecoin data is that the two series now have to be read separately. A flat supply chart no longer means adoption has stopped. Equally, rising payment volume does not mean more capital has entered the system. The first is a balance sheet; the second is an income statement, roughly speaking, and conflating them produces confident conclusions in both directions that the data does not support.

There is also a demand-side explanation sitting alongside the velocity one. A Bank for International Settlements working paper reported earlier this month found that stablecoin growth slows when US banks raise deposit rates, with Circle's USDC the most sensitive to the effect. If holding a non-yielding digital dollar costs more when a savings account pays more, the balance held will be the minimum needed to transact, which is precisely a world of flat supply and high velocity.

What this does not say

Allium's $482bn is payment volume, not profit, not revenue and not net new users. Payment figures in this sector typically count gross value transferred, which includes the same funds moving through multiple hops of a payment chain. The 45 percent growth rate is the number with the most information in it, because it compares the series against itself on a consistent method.

What it does establish is that a market widely described as stalled on its most-cited metric is not stalled on the metric that measures what the product is actually for. That is a distinction worth carrying into the next quarter of stablecoin coverage, particularly as card networks move more of this volume onto rails they operate themselves.
