Sui stablecoin supply climbs over 10% to $538M as the wider market shrinks

Sui’s stablecoin supply rose to $537.74 million on November 13, 2026. That is a 10.33% gain over the past 30 days.

The timing is what stands out. Over the same window, total US dollar stablecoin supply across all networks fell 5.34%, so Sui was filling up while the broader pool was draining.

The numbers behind the move

The figures come from on-chain trackers DefiLlama and stables.cool. Both point to Sui moving against the wider stablecoin market.

Across every network, dollar-pegged stablecoin supply stood at approximately $287.75 billion.

USDC does most of the heavy lifting on Sui. Circle’s stablecoin accounted for $368.42 million of the total on November 13, or 68.5% of the network’s stablecoin supply.

Sui’s native stablecoin, USDsui, is the second piece of the story. It holds around $72 million in supply.

That figure sits a little below its peak. USDsui reached an all-time high of $80.1 million in mid-October 2026, then pulled back modestly.

So the network’s homegrown dollar token has cooled slightly from its record. The overall stablecoin base still grew, which suggests the inflows came largely from USDC and other assets rather than USDsui alone.

What has been happening on Sui

The growth lines up with several developments on the network. The biggest structural one landed in May 2026, when Sui introduced gasless transfers for its stablecoins.

Gas is the fee a blockchain charges to process a transaction. Gasless transfers remove that cost for the person sending stablecoins, so moving dollars on Sui works more like sending a text than paying a toll.

Activity in decentralized finance, or DeFi, on Sui has also picked up. DeFi refers to lending, trading and yield apps that run on smart contracts instead of banks or brokers, and stablecoins are their main fuel.

Protocol fees on the network have risen alongside the stablecoin growth. Fees are a rough proxy for how much people are actually using the apps, as opposed to just holding tokens in a wallet.

There is also a treasury angle. The Sui Foundation uses yields generated from stablecoin reserves to fund buybacks of the SUI token.

Put plainly, the dollars sitting in reserve earn a return, and part of that return goes toward purchasing SUI on the open market. It ties stablecoin growth to the network’s native token in a direct, mechanical way.

Why the divergence matters

Stablecoin supply is one of the cleaner signals in crypto. Prices can swing on sentiment, but stablecoin balances reflect actual dollars that someone chose to move onto a specific chain.

Still, the gap is wide enough to notice. Sui grew by 10.33% while the market shrank by 5.34%, a spread of more than 15 percentage points in 30 days.

The concentration in USDC cuts both ways. Having 68.5% of supply in a widely used, regulated-issuer stablecoin gives the ecosystem a familiar base asset that exchanges and institutions already understand.

It also means Sui’s stablecoin story depends heavily on one issuer. If USDC balances leave, the headline number would fall quickly, and USDsui is not yet large enough to offset that.

USDsui is the variable to track. Its run to $80.1 million in mid-October showed there is appetite for a network-native dollar, but the slip to around $72 million shows that demand is not yet climbing in a straight line.

The buyback mechanism adds another layer. If stablecoin reserves keep growing, the yield available for SUI buybacks could grow with them, which may support confidence in the ecosystem’s longer-term plans.

The reverse also applies. A shrinking reserve base would leave less yield to deploy, so the buyback program is only as durable as the stablecoin inflows underneath it.

Gasless transfers give Sui a feature that is easy to explain to users who have no interest in how blockchains work.
