First credit rating for stablecoin issuer Sky
S&P Global Ratings has awarded crypto giant Sky (formerly Maker) a credit rating of B- with a stable outlook.

S&P Global Ratings has awarded crypto giant Sky (formerly Maker) a credit rating of B- with a stable outlook to Sky. It’s a first: a major traditional financial ratings agency has never before rated a DeFi protocol.
Sky, built on Ethereum, is the issuer of the USDS stablecoin, which, with a market cap of $7.1 billion, ranks fourth globally behind USDT, USDC, and USDe.
Jonathan Manley, Global Head of Market Outreach at S&P, called the rating “a significant milestone” that could help bring more transparency to the DeFi sector. S&P is expanding its coverage of blockchain-based financial products and has recently also reviewed tokenized Treasury Funds and mortgage-backed securities structured with blockchain.
In the separate Stablecoin Stability Assessment, S&P evaluates USDS’s ability to maintain its peg to the U.S. dollar on a five-point scale with a score of 4 (limited).
According to S&P, the main risks are:
- Mass withdrawals by users that exceed available liquidity
- Credit losses that exceed the available capital
On July 27, Sky had a risk-adjusted core capital ratio of just 0.4%, according to the assessment, indicating a limited buffer to absorb potential losses. S&P also notes a high concentration of large depositors, centralized management, dependency on the founder, and regulatory uncertainty.
The Stablecoin Stability Assessment was launched by S&P in December 2023. For comparison: Circle scores 2 (strong), while Tether — like Sky — sits at 4 (limited).
With this milestone, it’s further proof of how tightly intertwined traditional finance and the crypto market have become.
