支无不言：百亿爆仓惊魂夜后，再来谈谈 USDe

Core Insights - The cryptocurrency market experienced a significant crash on October 11, with major cryptocurrencies like BTC and ETH dropping over 10%, while many altcoins saw declines of up to 90%. The total liquidation amount across the market reached approximately $19 billion, with more reasonable estimates suggesting it could be between $30 billion to $40 billion [2][5][6] - A notable event was the "de-pegging" of the stablecoin USDe, issued by Ethena, which fell from $1 to $0.65 on Binance, leading to widespread liquidations of margin accounts that used USDe as collateral [2][8] - The incident has raised questions about the risk management practices of centralized exchanges and the mechanisms behind stablecoins, particularly in extreme market conditions [3][10] Market Impact - The crash on October 11 is considered the largest and most severe single-day liquidation event in the history of the cryptocurrency market, surpassing previous events like "312" and "519" [5][6] - The impact was felt differently across market participants, with retail investors experiencing significant losses, while institutional investors reported manageable drawdowns, primarily due to their cautious asset selection and risk management practices [6][7] USDe Mechanism and Issues - USDe is described as a "synthetic dollar" rather than a traditional stablecoin, relying on a collateralized model where large institutional market makers provide volatile assets as collateral to mint USDe [11][12] - The mechanism involves staking collateralized assets to generate returns, but the high leverage and circular lending model associated with USDe contributed to its price collapse during the market downturn [15][16] Risk Management and Future Outlook - The incident has highlighted the need for improved risk management practices within centralized exchanges, particularly regarding the treatment of new and less liquid assets like USDe [32][33] - Ethena's future strategy may involve transitioning to a fully compliant fiat-backed stablecoin model within three years, as mandated by U.S. regulations, while also maintaining a separate business line for its carry trade strategy [22][24] - The market is expected to face challenges as liquidity conditions change, with a potential shift towards more short-term speculative behavior among investors [37][38]
