S&P Global Grades Crypto Lending Vaults for Risk

S&P Global Ratings has introduced the Vault Risk Assessment, a framework that grades the risk of impairment in crypto lending vaults using letter grades with a 'v' suffix. The assessment scores a vault across six factors: portfolio credit quality risk, liquidity mismatch risk, curator risk, blockchain risk, protocol risk, and vault security and governance risk. This is the first time a major ratings agency has built a formal scoring system for this specific corner of decentralized finance.

The target market is roughly $10 billion in vault deposits, which has grown from $1.5 billion two years earlier. S&P Global's new framework is designed to catch the kind of risk that led to the collapse of Stream Finance's yield-bearing stablecoin xUSD in November 2025. The collapse resulted in a $93 million loss, leaving the token badly undercollateralized, and a subsequent contagion of roughly $285 million across the ecosystem.

The introduction of the Vault Risk Assessment is seen as a significant development for the sector, which has been criticized for its lack of transparency and risk management. S&P Global's ratings carry institutional weight, and will provide a credible external score for protocols like Morpho and Euler that build genuine risk controls.
