【Historic milestone: Moody’s rates a stablecoin protocol for the first time—an analysis of the balance sheet behind Sky Protocol’s B3 rating】
Moody’s Ratings, one of the world’s three major credit rating agencies, today officially assigned a long-term counterparty risk rating of “B3” with a “Stable” outlook to decentralized stablecoin protocol Sky Protocol (formerly MakerDAO, the issuer of USDS and DAI). This marks the first time in Moody’s history that it has issued an official credit rating for a decentralized stablecoin protocol.
Following S&P Global Ratings’ earlier B- rating, Sky Protocol has become the first—and currently the only—DeFi stablecoin protocol worldwide to receive formal ratings from both Moody’s and S&P.
【Moody’s core credit assessment and balance sheet analysis】
1. Thin capital buffer (a significant credit weakness):
The Moody’s report states that as of September 2026, the Sky Protocol held only about $90 million in tangible common equity (TCE), against approximately $10 billion in tangible managed assets (TMA), resulting in a capital ratio of just around 0.9% (below 1%). In scenarios involving extreme market volatility or asset impairment, its equity buffer for absorbing potential losses is relatively weak.
2. Rating support and positive defensive factors:
Despite the low capital buffer, Moody’s acknowledged Sky Protocol’s long-standing record of low credit losses, robust on-chain spread-earning capacity, and the significant share of highly liquid assets (such as short-term U.S. Treasury RWA and liquidity reserves) held in its managed assets. In addition, overcollateralization and automated liquidation mechanisms effectively reduce default risk.
3. Constraints and the threshold for a future upgrade:
Highly concentrated governance voting power, smart contract technology and operational risks, and regulatory compliance uncertainty across jurisdictions are the main constraints on the current rating. Moody’s explicitly noted that the protocol could be eligible for a rating upgrade if its tangible common equity can be sustained above 2.5% of managed assets (the protocol’s current reserve fund target is $150 million), while maintaining solid liquidity and earnings performance.
【Implications for institutional capital pricing and market structure】
Although B3 falls within the speculative-grade category, inclusion in the international dual-rating system represents a move toward the standardization and greater transparency of on-chain credit risk. For traditional institutions subject to strict risk-control and credit approval models, such as family offices and hedge funds, an independent external rating provides an objective basis for due diligence, laying a critical institutional foundation for yield-bearing stablecoins to penetrate traditional fixed-income and credit markets.
