Sui launched USDsui, its native stablecoin that directly reinvests yields from US Treasury bond reserves into its ecosystem through open-market SUI token buybacks and DeFi liquidity incentives. This model breaks with traditional practice where issuers like Tether keep billions in bond yields without sharing any value with the blockchains hosting their stablecoins. The platform had processed over $1 trillion in cumulative stablecoin transfers before launch, with $111 billion in volume in January 2026 alone, and SUI token price rose 3.86% on launch day. The buyback mechanism’s effectiveness scales directly with USDsui circulating supply: $100 million in reserves generates roughly $4-5 million in annual buybacks, while $10 billion in reserves would produce $400-500 million in annual buyback pressure.
