Synthetix 的算法稳定币 sUSD 继续偏离 1 美元的挂钩水平,目前交易价格为 0.90 美元。
脱钩始于3月份,sUSD一度跌破1美元。SIP-420(一项旨在提高资本效率并简化Synthetix (SNX) 生态系统内用户体验的治理提案)实施后,情况进一步恶化。根据Parsec的研究,SIP-420的实施无意中导致了sUSD供应量的大幅增加,从而引发了当前的脱钩。
具体来说,SIP-420 引入了一个协议自有的质押池,允许 SNX 持有者将其质押委托给共享池,而无需自行管理债务并铸造 sUSD。新的设置将抵押率从 500% 降至 200%,这使得铸造更多 sUSD 变得更加容易——据 Parsec 称,大约是 2.5 倍。这消除了稳定币的稳定机制——即当价格跌破挂钩水平时,激励个人质押者以折扣价购买 sUSD 来偿还债务。
现在,随着债务池的建立,质押者实际上已经没有机会恢复锚定汇率。再加上 420 池目前持有超过 8000 万美元的 SNX,sUSD 的供应量大幅增加,一些 Curve 流动性池的 sUSD 比例甚至超过 90%。由于缺乏立即平衡新增供应的需求,sUSD 的价格持续下跌。
更糟糕的是,在脱钩开始之前,Infinex 就开始激励用户在 Infinex 钱包中持有 sUSD。然而,这些激励措施导致系统流动性增加,却没有带来相应的需求。正如 Infinex Discord 频道上的一位用户写道:“你们通过活动推广 sUSD,你们应该承担责任。”
The Synthetix team has reassured users that this is a âtransition period.â Theyâre working to create new demand sinks, such as Aave (AAVE) and Ethena (ENA) integrations, to counterbalance the excess supply of sUSD. Additionally, they have promised to bolster incentives for liquidity pools, particularly on Curve, to restore stability.
To summarize, the SIP-420 upgrade has brought capital efficiency and a simpler UX to Synthetix, but it has removed the organic reflexive peg stabilizer, resulting in the sUSD depeg as a side effect. By moving to a protocol-owned staking pool and lowering the collateralization ratio, SIP-420 has led to an increase in the supply of sUSD without sufficient demand to counterbalance it. This has caused the stablecoin to depeg, with the price currently hovering around $0.90. This means sUSD holders are left with a choice: exit now or hold and wait for full recovery.
