S&P Global Ratings Introduces a Risk-Rating Method for On-Chain Lending Vaults
S&P Global Ratings has published a Vault Risk Assessment methodology for on-chain lending vaults, analysing risk across six items including curators and protocols, as custodied assets have grown to around $10 billion.

What happened
S&P Global Ratings has published a risk-rating methodology for on-chain lending vaults, called Vault Risk Assessment. According to CoinPost, the method analyses risk across six items, including curators and protocols, and individual assessments will be published later. Custodied assets have grown to approximately $10 billion.
The arrival of a rating methodology is a process change rather than a rating action. No vault is being rated here. What has been published is a framework, and a framework matters because it fixes what a question about a DeFi vault has to answer before anyone can compare two of them.
Why vault structure needs a standard method
A lending vault is a claim that runs through a chain of parties. The depositor’s return depends on the curator’s allocation choices, which depend on the protocol’s mechanics, which depend on the underlying borrower behaviour, and any of those can be a point of failure. Rating a vault therefore means rating a structure, not an issuer, because no single entity carries the whole exposure the way a bond issuer does.
A methodology that separates six such factors does something specific: it forces a distinction between a vault that fails because a curator allocated badly and one that fails because a protocol design was exploited. Those have different remedies, and collapsing them into a single rating would hide the difference.
What the scale figure implies
The roughly $10 billion figure is what makes a method timely rather than premature. A framework written for an experimental product can afford to be rough; a framework intended to be applied at ten billion dollars of custodied assets cannot. The remaining open questions are the individual assessments, and the methodology is only useful to the extent that applying it produces discriminating results across the six factors.
Evidence boundary
This account follows CoinPost’s report, translated from the Japanese source. The six factors are not enumerated in the material available here, no vault has been assessed under the method, and the $10 billion and 6.7x growth figures are as reported by that source.
