最新报道:S&P Global Ratings assigns a speculative-grade "B-" with a Stable outlook to Sky Protocol, operator of the fourth-largest stablecoin USDS, marking the first credit rating for a DeFi protocol. The assessment, adapted from nonbank financial institution frameworks, highlights Sky’s systemic importance but criticizes its thin 0.4% risk-adjusted capital ratio, heavy exposure to high-risk USDe (11% allocation with 1,250% risk weight), and governance vulnerabilities. While Sky benefits from diversification and strong cybersecurity, S&P’s Basel-inspired analysis underscores structural weaknesses, including concentrated control and regulatory uncertainty. The rating sets a precedent for institutional engagement with DeFi, emphasizing the tension between capital efficiency and traditional financial safeguards.
