Sky has disclosed more than $4.4 billion in aggregate stablecoin liquidity in its Peg Stability Module (PSM), drawing attention to the difference between converting USDS into another token and ultimately receiving bank dollars.
The disclosure, reported by CryptoSlate, concerns Sky’s October 9 explanation of how its conversion mechanism works. The PSM provides a direct route between USDS, Sky Protocol’s dollar-linked token, and USDC at a one-for-one rate. However, the amount of USDC available on that route is the relevant constraint for a holder trying to exit USDS at a particular moment.
Liquidity is not the same as new bank-dollar demand
The $4.4 billion figure represents aggregate stablecoin liquidity disclosed by Sky. It should not automatically be read as an equivalent amount of fresh dollars entering the crypto system, nor does it guarantee that the entire amount is available as USDC for every transaction.
Several types of activity can increase or reduce the reported quantity of a token without creating a matching deposit of bank money. Existing DAI can be converted into USDS, while borrowing against collateral can create new spendable stablecoins backed by an obligation to repay. A holder can also migrate an older token into a newer version. These events alter token balances or their denomination, but they do not necessarily represent new external cash entering the system.
Sky’s documentation describes a DAI–USDS converter that allows holders to move between the two tokens in either direction without liquidity restrictions. Because both tokens share an issuance source, a rise in USDS viewed in isolation may simply reflect a change in how an existing position is labeled. The DAI side must also be considered when assessing whether the underlying economic position has grown.
USDD provides another example. Its vault system allows users to deposit collateral, mint USDD debt and later repay the tokens, together with stability fees, to release the collateral. Users may also withdraw collateral while maintaining sufficient coverage. This can create transaction liquidity against assets that are already held, but the collateral’s value is not the same thing as a readily available pool of redemption cash.
USDD also has a migration route from USDDOLD into an equivalent amount of new USDD. The migration carries gas costs but has no deadline. As a result, looking at the old and new contracts separately can make an existing position appear to have increased when it has instead been upgraded.
Converting USDS to USDC is only the first step
Sky says the direct USDS–USDC PSM leg operates through liquidity already held inside the protocol. At the settings described in the October explanation, it has no protocol swap fee or slippage. A route that passes through another token pool may still incur that pool’s own pricing, liquidity constraints and fees.
Sky also reported approximately $1.6 billion in cumulative USDC–USDS volume processed through Uniswap routing by October 6, after the integration launched on July 8. That is a turnover measure: it can include transactions in both directions and repeated conversions. It does not measure net USDS issuance or the amount of new dollars deposited into crypto markets.
For someone seeking USDC, the practical question is how much USDC the relevant route can deliver when the transaction is made. The same principle applies to other stablecoins. A PSM may offer one-for-one conversion, but users still need to check the displayed quantity of the target asset and remain within the available inventory.
Receiving USDC is also different from receiving dollars in a bank account. Circle’s issuance and redemption process is the separate fiat-facing stage. Eligible businesses can deposit dollars into Circle accounts to receive newly minted USDC, while returning USDC for dollars removes those tokens from circulation. Circle says its reserves consist of highly liquid cash and cash equivalents, with most held through the Circle Reserve Fund, which can contain short-dated US Treasuries, overnight Treasury repurchase agreements and cash.
A purchase on an exchange may instead use USDC that the exchange already holds. In that case, the buyer’s demand does not necessarily cause a new issuance transaction at that time.
Market picture
Moneyiar market data at 20:48 on October 13, 2026, puts Sky (SKY) at $0.0766593093, down 1.73% over 24 hours and 14.32% over seven days.
The other assets in the supplied Moneyiar snapshot were recorded at different times: Light (LIGHT) was $0.1672899542, up 1.73% over 24 hours and down 9.40% over seven days at 02:53 on September 14, 2026; Comedian (BAN) was $0.058731235, down 2.20% over 24 hours and 10.45% over seven days at 20:48 on October 13; and Billions Network (BILL) was $0.0139971939, down 0.59% over 24 hours but up 10.04% over seven days at 01:39 on September 21.
For eligible retail holders in the European Economic Area, Circle France provides a separate direct route for USDC redemption. Circle’s MiCA policy requires eligibility, identity and transaction checks, plus an EEA bank account able to accept US dollars. The policy gives eligible retail users a timeframe of up to five business days unless discrepancies arise, and allows delays during a stress event that prevents reserve rebalancing between Circle France and Circle LLC.
That distinction is central to the liquidity disclosure. A USDS holder may first convert USDS into USDC through Sky’s PSM. The subsequent conversion of USDC into bank dollars must still pass through the issuer and banking channel, with its own eligibility requirements, inventory considerations and settlement timing.
