Stablecoin payments climbed 45% year-over-year to $482 billion in the year through September 30, according to data from Allium. Transaction counts rose even faster, up 71% to 1.04 billion. Yet the total circulating supply of stablecoins grew just 0.4% over the same stretch.
That gap is the story. The dollars already sitting in wallets are moving far more often than they were a year ago, while almost no new coins have been minted. CoinDesk's Krisztian Sandor reported the figures.
More work, same pile of coins
A 0.4% supply increase is close to flat. For an industry used to watching market caps expand and contract with the crypto cycle, it's an odd number. Stablecoin supply usually tracks net inflows: bull markets bring new dollars in, bear markets drain them out. This year it's done neither, at least not at the scale the payment volumes would suggest.

What that means in practice is that each coin is being used more frequently. A stablecoin that sat in a trading account a year ago might now be moving through a payment processor, a remittance corridor, or a settlement desk. The velocity is up. The float isn't.
Smaller tickets, more of them
Transaction growth outran payment value growth by a wide margin: 71% versus 45%. When the count rises faster than the dollar total, the average transaction gets smaller. That points to retail and remittance activity rather than large institutional transfers, where a handful of big tickets would typically push value up without a matching jump in volume.
Smaller payments are stickier. They're less tied to crypto market sentiment and less likely to reverse when prices drop. They also generate more fee revenue per dollar moved for the infrastructure layer — the processors, on-ramps and analytics firms that charge on volume rather than on reserves.
The flat-supply question
Why supply has barely moved is the open question the data doesn't answer. Stablecoin issuance normally responds to demand, and demand for payments is clearly rising. One possibility is that holders are rotating into yield-bearing instruments outside the stablecoin supply count. That's a competitive pressure on the largest issuers, whose business models lean on interest earned from reserves rather than transaction fees.
The Allium figures measure payments using its own methodology. That's worth keeping in mind: definitions of what counts as a payment — versus an exchange transfer or a collateral shuffle — vary by provider, and the headline number depends heavily on where those lines are drawn.
What to watch next
Allium's data is year-to-date through September 30, so the next checkpoint is how the fourth quarter lands. If transaction growth keeps outpacing supply growth, the velocity story holds. If supply starts to climb again, it would suggest new capital is finally arriving rather than the existing stock simply turning over faster. Either way, the spread between the 71% transaction number and the 0.4% supply number is the figure to track.
