A report from Sentora Research highlights that approximately $1 billion in decentralized finance (DeFi) positions involving Ethena's staked USDe (sUSDe) are at risk following the market crash on October 10. The crash led to a sharp decline in DeFi rates, resulting in a negative yield differential for sUSDe loop trades. This situation threatens the unwinding of leveraged positions on platforms such as Aave v3 Core, potentially impacting the broader DeFi ecosystem.
