Moody's rates Sky Protocol B3 over a capital cushion under 1% of assets
Moody's rated Sky Protocol B3, its first stablecoin-protocol rating, citing about $90 million of equity behind roughly $10 billion of assets. That cushion is under 1%, well short of the 2.5% capital ratio Moody's set as its bar for an upgrade.

What happened
- Moody's issued the speculative-grade rating on October 7, 2026, and set a stable outlook on it.
- S&P Global Ratings gave Sky a B- earlier in October, so Sky is the only stablecoin protocol rated by both agencies.
- Sky's reserves rose from about $50 million earlier in 2026 to an estimated $92 million by September 17, helped by a buyback program aimed at building them.
- Moody's said a capital ratio below 0.5%, consecutive quarterly losses or weaker liquidity could push the rating lower.
- Moody's noted that Sky has no audited financial statements, formal incorporation, employees, officers or directors.

Why it matters
- exposure If losses outrun Sky's equity and a sale of newly minted governance tokens fails to cover them, USDS and DAI holders take the write-down.
- constraint Every extra $1 billion of USDS or DAI needs $25 million more equity to hold the ratio at Moody's 2.5% upgrade level, so supply growth without reserve growth works against the rating.
- capability Allocators whose mandates require a standardized credit assessment before buying now have two for Sky, Crypto Briefing noted, even though both grades are speculative.
Divide one figure by the other and the cushion is 0.9% of assets [18]. At the top of the $10 billion to $11 billion range Moody's research uses for managed assets, it is about 0.8% [5][19]. Moody's called the position a "material credit weakness" [4]. Treat the stablecoins as the liabilities and each dollar of USDS and DAI sits on roughly $1.009 of assets [24].
The defense rests on asset quality. About 45% to 50% of the book is stablecoins and tokenized money market funds [14], and the protocol has recorded about $15 million of cumulative losses since 2020 [13], roughly a sixth of today's equity [27]. The weaker part is the roughly 25% in crypto-backed loans [14], about $2.5 billion at $10 billion of assets [25]. A 3.6% loss on that book alone would erase the $90 million [26] before the governance-token backstop is ever tested.
Moody's put both sides in one sentence. "These positives are counterbalanced by Sky Protocol's very low capitalization, confidence-sensitive stablecoin liabilities, and the inherently elevated operational, governance, legal, and regulatory risks associated with its DAO structure, smart-contract infrastructure, and permissionless stablecoin model," the rating states [7].
The upgrade threshold is where the deal terms get interesting. At $10 billion of assets, a 2.5% ratio means $250 million of equity, $160 million more than Sky has [28]. Sky's own medium-term goal is $150 million [8]. That gets the ratio to 1.5% [20]. The other route to 2.5% is shrinking: with equity held at $90 million, assets would have to fall to $3.6 billion [29]. The downgrade side has more room. With equity flat, assets would have to grow to $18 billion to drag the ratio to 0.5% [21]. Against today's $10 billion, though, the roughly $50 million of reserves Sky held earlier in 2026 would have sat right on that line [22].
If reserves keep compounding at the pace that added about $42 million, or 84%, in part of a year [23], governance can raise its goal and the ratio climbs. If supply grows faster than reserves, Crypto Briefing says the ratio stretches further [16]. If a loss in the loan book arrives first, the cushion shrinks before it has been built.
I'd expect the rating to stay where it is. Moody's stable outlook signals no expected move [3], and Sky's plan aims at 1.5%, below the level the agency named. Sky is building reserves (or rather, building them toward a target that leaves it at B3 by design), and it has not set a goal pitched at the upgrade line. The counter-case is the loss record: $15 million since 2020 means the thin cushion has rarely been drawn on [13]. A governance vote that sets the target at or above $250 million would prove this view wrong.
What to watch
- The next reserve estimate after September 17's $92 million, set against combined USDS and DAI supply that Crypto Briefing puts at $9.5 billion to $11 billion.
- Any move off the stable outlook by Moody's, or a split between Moody's B3 and S&P's B- as Sky's capital changes.
