Is USDS (USDS) Halal? Reserves, Interest and the Verdict

Here is the thing that trips people up about USDS: it looks like just another dollar token, so they assume the ruling is the same as USDC or USDT. It is not, and the reason sits right in the plumbing. USDS is the flagship stablecoin of Sky Protocol, which is the rebrand of MakerDAO that finished its transition in 2024 and 2025. USDS is the direct successor to DAI. And unlike Circle's USDC, which parks cash and short Treasuries in a bank, USDS is minted against a pool of over-collateralized crypto and real-world assets, and it comes bolted to a savings engine that pays interest. So when you ask "is USDS halal," you are really asking two different questions at once, and they have two different answers.

Let me walk through both, then give you the four-faith verdict.

What USDS actually is

USDS is a dollar-pegged stablecoin issued by Sky Protocol on Ethereum, with a bridged version on Base. Supply sits around 9 billion dollars in mid-2026, which makes Sky roughly the third-largest dollar stablecoin issuer once you add the legacy DAI float, behind Tether and Circle.

The peg holds through two mechanisms. First, USDS is minted when users lock collateral (crypto like ETH-backed vaults, plus tokenized real-world assets) at over-collateralized ratios. Second, the Peg Stability Module lets anyone swap USDS for USDC at exactly 1:1 in either direction, with fees currently set to zero by Sky governance. That PSM is why USDS tracks a dollar tightly rather than floating like a volatile token. You can watch the collateral live on-chain through Etherscan, MakerBurn, and DeFiLlama, with the exception of the RWA loans, which lean on off-chain attestations from partners.

That is the holding side. Now the part that matters for the ruling.

Sky runs the Sky Savings Rate (SSR). Deposit USDS into the savings module and you get sUSDS, a non-rebasing token whose USDS redemption value climbs block by block. In Q2 2026 that rate is set at 3.75% APY, down from peaks above 8% in 2024. The yield comes from Sky's collateral portfolio: Treasury bills held through RWA partners, crypto-collateralized lending positions, and protocol-owned liquidity. Read that sentence again, because the T-bill interest and the on-chain lending spread are exactly where the riba question lives.

Islamic verdict: the coin versus the yield

Start with USDS the token, held flat in your wallet. Is it mal mutaqawwim, property with recognized value under the Shariah? The permissive camp says yes. The Shariah Advisory Council of Malaysia's SAC ruled in 2019 that digital assets can be treated as mal and traded, since they carry urf-recognized value and function as a medium of exchange. Under that lens a dollar-pegged token that reliably holds its peg is closer to a digital representation of currency than to a speculative gamble, so gharar from volatility is minimal by design. The whole point of USDS is that it does not swing.

The prohibitionist camp, led by Mufti Taqi Usmani and the Darul Uloom Karachi scholars, has generally rejected cryptocurrencies as lacking intrinsic value (mal) and as vehicles for maysir and gharar. Applied honestly, that critique bites hardest on volatile coins bought to flip. A fiat-pegged stablecoin used as a settlement rail is a harder target for the "it is pure speculation" argument, but the school's deeper objection, that these instruments lack the backing and legal recognition of real currency, still applies to some in that camp. This is INFERENCE, not a settled ruling: no major body has issued a specific fatwa on USDS by name, so you are reasoning from the general positions.

Where scholars like Sheikh Yaquby and the Amanie team tend to land is more granular. They look at what backs the thing and what it pays. And here USDS has a real problem the moment you touch the savings side.

The Sky Savings Rate is interest. Not "interest-like," not a gray area you can rationalize. sUSDS pays a fixed, predetermined return funded substantially by Treasury bill coupons and interest-bearing lending spreads. That is riba al-nasiah, the interest on deferred money that the Quran condemns directly in 2:275 through 2:279. A guaranteed 3.75% on a dollar deposit, sourced from bond interest and loan interest, is close to the textbook definition. There is no profit-and-loss sharing, no ownership of a productive asset, no risk you actually bear. You put in dollars, you get more dollars back, and the "more" comes from lending at interest. DOCTRINE here is clear: earning the SSR is not permissible.

So the Islamic verdict splits by activity, which is the only honest way to screen this coin.

Holding versus staking versus lending versus LP

Holding USDS flat. Broadly acceptable under the permissive Malaysian-style view, provided you treat it as a payment and settlement tool, not a speculative position. You hold the peg, you spend or transfer, you earn nothing. The riba engine is opt-in, and you have declined it. The residual caution is the prohibitionist objection to crypto as mal at all, plus a note on the collateral: some of what backs USDS is itself interest-bearing paper, which purists flag even for holders. Most contemporary screening treats passive holding of a payment stablecoin as tolerable.

Staking into sUSDS. This is the Sky Savings Rate, and it is the riba path. Depositing USDS to mint sUSDS and collect the SSR is earning interest on money. Avoid it. The Shariah Review Bureau's staking taxonomy is useful here: it distinguishes protocol staking that secures a network and earns genuine block rewards from what is really disguised lending. sUSDS is the second kind. It is not proof-of-stake validation, it is a deposit that pays a coupon.

Lending USDS. Same problem, more obvious. Supplying USDS to a money market like Aave or Sky's own lending venues to earn a borrow-side interest rate is straightforward riba.

Providing liquidity (LP). More nuanced. A USDS/USDC stable pool earns swap fees, which several scholars treat as a service fee (ujrah) rather than interest, and that can be acceptable in principle. But most real-world USDS LP positions come layered with reward emissions and auto-compounding into interest-bearing legs, and stable-stable pools carry impermissibility risk if either leg pays yield. You would need to screen the specific pool, not assume.

The clean rule: hold it, do not farm it.

Christian, Jewish and LDS verdicts

Christian (BRI and USCCB). Faith-based Responsible Investing screens on six categories (abortion, addictions, and so on) and the USCCB guidelines exclude specific product lines. A dollar-pegged token issued by a decentralized protocol does not obviously trip any BRI category, and it is not a company you can screen for revenue exposure. The historic Christian concern here is usury, the old prohibition on lending at interest. Holding USDS raises none of it. Chasing the Sky Savings Rate revives the exact thing scholastic theologians warned against, so a conscience-driven Christian investor treating usury seriously should hold rather than farm, which lands in the same place as the Islamic verdict.

Jewish (Halakhic, Bais HaVaad). The prohibition is ribbis, interest between Jews, and the Bais HaVaad framework runs a two-tier analysis: biblical ribbis ketzutzah (fixed, stipulated interest) versus rabbinic avak ribbis (the dust of interest). A fixed SSR paid on a dollar deposit looks like stipulated interest, which is the more serious tier. In practice, Jewish law permits interest-style returns through a heter iska, a structured partnership document that reframes the arrangement as a profit-share. USDS ships with no heter iska, so absent that structure, earning the SSR is problematic. Holding USDS as a payment instrument is fine.

LDS (Word of Wisdom and the Oaks warning). The Word of Wisdom is about substances, not securities, so it is silent on tokens. The relevant teaching is Dallin H. Oaks' 1971 warning against speculation, the counsel that Latter-day Saints should avoid get-rich-quick gambling dressed up as investing. A stablecoin is the least speculative thing in crypto, so holding USDS as cash-equivalent is not what Oaks was warning about. The caution flips if you are yield-chasing across DeFi protocols hunting the highest APY, since that behavior, not the coin, is the speculation.

The FaithScreener verdict

Across all four frameworks the pattern is the same, and it is unusually consistent for a crypto asset: the token is acceptable to hold, the yield is not acceptable to earn. USDS passes as a settlement and cash-management tool for Muslim, Christian, Jewish, and LDS investors who use it to hold and transfer dollars. It fails the moment you route it into sUSDS, lending markets, or interest-bearing pools, because the return is riba by any of the four definitions.

That split is the whole story. Two investors can both "own USDS" and one is compliant while the other is not, depending entirely on whether they opted into the Sky Savings Rate. Most stablecoin screening misses this because it stops at "is the peg backed." With USDS you have to look one layer deeper at what the protocol is paying you and where that money comes from.

You can check USDS live at faithscreener.com/crypto/USDS, which breaks out the holding, staking, and lending verdicts separately rather than giving one blanket rating. If you want to compare it against other stablecoins and the 3,300-plus tokens in the database, start at the crypto screening hub, and the multi-faith framework page lays out exactly how the Islamic, BRI, USCCB, Halakhic, and LDS lenses each reach their call.

The Bottom Line

USDS itself is fine to hold as a dollar-pegged payment token under all four faith frameworks, with the usual prohibitionist caveat on crypto as mal. The Sky Savings Rate is where it breaks: sUSDS, lending, and most yield strategies pay interest funded by Treasury bills and lending spreads, which is riba for Muslims, usury for conscientious Christians, stipulated ribbis without a heter iska for Jewish investors, and beside the point for the Word of Wisdom while still speculative if you chase it. The one thing to remember: with USDS the coin and the yield have different rulings, so screen the activity, not just the ticker.
