DeFi Stablecoin Failures Reveal Structural Risks and Repeated Mistakes

Derived from TechFlow, the recent collapse of Stream Finance's xUSD and the subsequent failures of Elixir's deUSD and other synthetic stablecoins have exposed deep-rooted structural issues in the DeFi ecosystem. The events, which led to a 40-50% loss in total value locked for yield-bearing stablecoins within a week, highlight problems in risk management, transparency, and trust. Stream Finance's recursive lending model, which inflated xUSD supply 7.6 times beyond its verified collateral, triggered a chain reaction across multiple protocols, including Elixir, Morpho, and Euler, with total risk exposure reaching $285 million. Analysts have pointed out that the industry continues to repeat past mistakes, with high-yield promises often masking unsustainable leverage and opaque strategies. The failures underscore the fragility of interconnected stablecoin systems and the urgent need for improved infrastructure and risk controls.
