Moody's assigned Sky Protocol a B3 issuer rating with a stable outlook on October 7, marking the first time the agency has rated a stablecoin issuer. The grade lands in speculative territory, reflecting what the agency described as a vulnerable capital structure set against roughly $10 billion in managed assets.

The credit assessment puts Sky's equity and reserves at approximately $90 million. Against managed assets in a $10 billion to $11 billion range, the equity cushion comes in below 1%. Sky, the rebranded MakerDAO, issues USDS and DAI, two tokens that anchor a combined supply estimated between $9.5 billion and $11 billion.

What does the B3 grade actually signal?

Moody's placed the rating in speculative-grade territory, six notches below investment grade. The stable outlook indicates the agency does not currently expect a directional move in either direction.

The arithmetic does the work. With managed assets dominated by stablecoin collateral and only about $90 million sitting on the equity side, the issuer's loss-absorption capacity is thin relative to the size of the float it supports.

How did Sky's reserves get to $92 million?

Sky Reserves, the protocol's designated capital buffer, has been growing deliberately. Reserves stood near $50 million earlier in 2026. By September 17, they had reached an estimated $92 million, according to Moody's research.

Much of that growth traces to decisions by Sky governance, including a strategic buyback program aimed at thickening the buffer. Sky governance has also set a target of $150 million in reserves.

Where does S&P fit in?

Sky is now the only stablecoin protocol carrying ratings from both major agencies. S&P Global Ratings assigned Sky a B- grade earlier in October 2026.

The dual coverage matters for institutional allocators. Large investors typically operate under mandates that require a standardized credit assessment before they can allocate. Sky now holds two.

What changes for institutional capital?

The existence of the ratings may matter more than the letter grades themselves. Mandates that gate allocation behind a Moody's or S&P assessment now have a pathway to clear for the first time on a stablecoin issuer.

The ratings explicitly flag the low equity-to-assets ratio. Any growth in stablecoin supply without matching growth in reserves would compress that ratio further. Reaching the $150 million governance target would materially improve the buffer relative to where it sat earlier this year.

What to watch next

The next inflection point sits at $150 million. Sky governance has named that figure as the reserves target, and the path from roughly $92 million to that line will test whether the protocol can keep thickening its capital buffer at the same pace it managed through the third quarter.

If reserves keep climbing on the current trajectory, the equity-to-assets ratio lifts off its previous lows and the speculative-grade label becomes a narrower description of the underlying capital structure.
