Moody’s assigns B3 rating to Sky, flags thin capital buffer

Sky Protocol, the DeFi heavyweight formerly known as MakerDAO, now has a Moody’s credit rating. The grade is B3 with a stable outlook, which places it in speculative-grade territory.

The headline number behind that verdict is roughly $90 million in equity and reserves, set against about $10 billion in managed assets.

What Moody’s actually said

Moody’s Ratings issued the inaugural issuer rating on October 7, 2026. That makes Sky the first stablecoin protocol the agency has rated.

The speculative-grade label reflects what Moody’s sees as a vulnerable capital structure. The agency’s research puts managed assets in a range of $10 to $11 billion, depending on the measure. Those assets mostly back Sky’s two stablecoins, USDS and DAI.

Do the arithmetic on roughly $90 million against about $10 billion, and the equity cushion comes out under 1% of assets.

The stable outlook signals that Moody’s does not currently expect the rating to move in either direction.

The reserves story

Moody’s gave weight to Sky Reserves, the protocol’s capital buffer. That buffer has been growing at a noticeable clip.

Reserves sat at around $50 million earlier in 2026. By September 17, they had reached an estimated $92 million.

Much of that growth reflects deliberate governance choices, including a strategic buyback program aimed at building up reserves. Sky’s governance has also set a target of $150 million in reserves.

A second opinion from S&P

Moody’s is not the only traditional rater to weigh in. S&P Global Ratings gave Sky a B- rating earlier in October 2026.

That leaves Sky as the only stablecoin protocol carrying ratings from both agencies.

How Sky got here

Sky is the rebranded MakerDAO, one of the longest-running projects in decentralized finance. Its DAI stablecoin became a foundational piece of DeFi infrastructure, and USDS now sits alongside it.

The combined supply of USDS and DAI is estimated at approximately $9.5 to $11 billion. A network of Prime Agents helps manage that capital, engaging in over-the-counter lending and other strategies to deploy it.

What this means

For institutional allocators, the most important part of this news may be the existence of the ratings rather than the grades themselves. Large investors often operate under mandates that require a standardized credit assessment before they can touch an asset. Sky now has two.

The ratings explicitly highlight the low equity-to-assets ratio, and any growth in supply without matching growth in reserves would stretch that ratio further.

That makes the $150 million reserve target the number to watch. Hitting it would materially improve the buffer relative to where things stood earlier this year.
