Yield-bearing stablecoin supply drops $3.5B, ends 3-year growth

Yield-bearing stablecoin supply contracted by more than $3.5 billion in the second quarter, a 15% decline that snapped a nearly three-year streak of quarterly growth. The drop was led by Ethena's sUSDe and Sky's sUSDS, two of the largest crypto-native yield products, while Treasury-backed alternatives BUIDL and USYC posted gains.

The shift exposes a growing divergence in the market for yield-bearing stablecoins. Products tied to crypto-native strategies such as funding rates and basis spreads lost ground. Tokens backed by short-term U.S. Treasury debt absorbed the demand. BUIDL, issued by BlackRock through Securitize, and USYC, from Hashnote, each saw supply increases.

Ethena's sUSDe, the largest crypto-native yield stablecoin by market cap, contracted alongside its sister token sUSDS from Sky (formerly MakerDAO). Both had ridden the bull market's funding-rate wave. The second quarter brought lower funding rates and tighter basis spreads, cutting the appeal of those strategies.

The Treasury-backed group operates differently. BUIDL and USYC pass through the yield on their underlying bond holdings, offering a predictable return that does not depend on crypto derivatives market conditions. That predictability appears to have drawn investors during a quarter when crypto spot markets mostly traded sideways.

Industry data from DeFiLlama and other tracking services shows total yield-bearing stablecoin supply ended June at roughly $19.5 billion, down from $23 billion at the end of March. The decline ends a streak that stretched back to late 2021, when the category first emerged as a distinct segment of the stablecoin market.

The contraction in crypto-native products removes a source of demand for perpetual futures and basis trades, which can affect exchange volumes and funding rates. For Ethena, lower sUSDe supply reduces the collateral base supporting its synthetic dollar system, potentially compressing future returns.

The second quarter's shift toward tokenized Treasury products blurs the line between stablecoins and money-market funds. BUIDL, for example, is a tokenized money-market fund whose yield competes directly with traditional short-term fixed-income products.

The 15% quarterly drop ends almost three consecutive years of growth. Whether the category resumes its expansion likely depends on the return of favorable funding conditions or continued investor appetite for tokenized Treasury products.
