Is Ondo US Dollar Yield (USDY) Halal? Reserves, Interest and the Verdict

Open the USDY page on a data tracker and you will notice something a normal stablecoin never does: the price is not $1.00. In January 2026 it was hovering around $1.12, and it keeps climbing. That premium is not a depeg or a bug. It is the whole point of the token. USDY is designed to get more expensive over time, and the reason it gets more expensive is interest earned on US Treasuries. So the question "is Ondo US Dollar Yield halal" is really a question about where that rising number comes from, and once you see the plumbing, the answer gets a lot clearer than it is for most coins.

What USDY actually is

USDY is a yield-bearing token from Ondo Finance, backed by short-duration US Treasury bills and bank demand deposits. As of April 2026 the reserve was roughly 92% Treasuries and 8% cash sitting in insured banks for redemption liquidity. The Treasuries are custodied at Morgan Stanley, and each token represents a senior unsecured claim on a portfolio held by Ondo USDY LLC, a Delaware bankruptcy-remote entity. Ondo keeps the reserve overcollateralized by about 4%, so roughly $104 of assets stand behind every $100 of tokens. By early 2026 the product had grown to around $1.4 billion in total value, making it one of the largest tokenized Treasury instruments on-chain.

Here is the part that matters. USDY is not built to hold a peg. It comes in two flavors. The accumulating version (USDY) has a price that rises as yield accrues, which is why it was near $1.12 in January 2026 instead of $1.00. The rebasing version (rUSDY) keeps a $1.00 price but drips extra tokens into your wallet each day. Either way, you are receiving the interest that the underlying Treasuries and deposits throw off, recently in the ballpark of 3.5% APY, moving up and down in lockstep with short-term T-bill rates. Access is gated to non-US investors with KYC, and you can trade it on venues like Curve, Orca, and Aerodrome once you hold it.

So this is not USDC or USDT, where the issuer keeps the interest and hands you a flat dollar token. With USDY, the interest is the feature. You are the one collecting it.

The Islamic verdict: the coin is money, but the yield is riba

Two separate questions here, and they get two different answers.

First, is USDY valid property? On the property question, USDY looks fine. It is mal (recognized wealth) with taqawwum (lawful market value): it is fully backed by real assets, it is not a governance or meme token with nothing behind it, and holders have an actual legal claim on a segregated portfolio. Gharar (excessive uncertainty) is low by crypto standards, since the reserve is disclosed, audited-style attested, and dominated by the safest dollar instrument that exists. Depeg risk is real but modest: the main failure modes are a Treasury market dislocation, a banking failure on the deposit sleeve, or a legal problem inside the bankruptcy-remote structure. There is no maysir (gambling) baked into simply holding it. On structure alone, USDY is one of the cleaner tokenized products out there.

Second, and this is the one that decides it: what is the yield? US Treasury bills are interest-bearing government debt. The return on a T-bill is riba al-nasiah, the interest-on-a-loan-over-time that Quran 2:275 to 2:279 addresses directly and that AAOIFI standards treat as prohibited without exception. Bank demand deposits pay interest the same way. USDY takes that interest and channels it straight to the token holder, either through a rising price or through daily rebased tokens. When you hold USDY and watch it climb from $1.00 toward $1.12, you are receiving conventional interest with an extra step in between. The tokenization does not launder the source.

This is different from the live scholarly debate over plain stablecoins and over crypto generally. On general crypto you have the Karachi prohibitionist camp associated with Mufti Taqi Usmani, who has argued digital tokens lack intrinsic value and function as speculation, versus the more permissive line from Malaysia's Shariah Advisory Council (SAC), which recognized digital assets as tradable property in 2020, with scholars like Sheikh Nizam Yaquby and the Amanie team taking case-by-case views. That split is genuine and it maps onto tokens whose Islamic status is contested. USDY is not really in that gray zone. Even the permissive Malaysian-style reasoning that would accept an asset-backed digital token does not accept a token whose defining function is to pay you interest. The permissive camp gets you past "is it property." It does not get you past "the return is riba." On the yield question the schools converge, and the answer is that holding a yield-bearing Treasury note, wrapped or not, means receiving riba.

Contrast rUSDY or accumulating USDY with a hypothetical fully-reserved, non-yield stablecoin where the issuer keeps the interest. That coin has a live debate. USDY hands the interest to you by design, which removes the debate. You can screen it live and see the crypto report rather than take my word for it.

Holding vs staking vs lending vs LP

The activity layer usually changes a coin's ruling. With USDY it mostly does not, because the riba is already present at the holding layer.

Holding USDY or rUSDY: you are receiving Treasury interest. Impermissible on the riba ground, per the reasoning above.

Lending or borrowing USDY on a DeFi money market: this stacks a second interest layer on top. You would be earning or paying protocol interest on an instrument that is itself an interest pass-through. Two riba problems, not one.

Providing liquidity (LP) in a USDY pool on Curve or Orca: LP fees from facilitating swaps are closer to a service income and are less obviously riba on their own, but you are still holding USDY as inventory the entire time, which means you are still accruing the underlying interest. The base problem follows you into the pool.

Staking: USDY is not a proof-of-stake network token, so there is no native validator staking here in the sense the Shariah Review Bureau's staking taxonomy addresses. Any "staking" you see advertised for USDY is really lending or yield-farming under a friendlier name, and it inherits the lending analysis above.

Across all four activities, the interest sits at the bottom of the stack, so none of them rescue it.

Christian, Jewish, and LDS lenses

The other frameworks are less unanimous than Islam here, and it is worth mapping honestly.

Christian, Biblically Responsible Investing (BRI): the classic BRI six-category screen targets abortion, pornography, gambling, tobacco, alcohol, and anti-family or anti-Christian activity. A tokenized Treasury does not obviously trip any of those. Historic Christian teaching did condemn usury, and some conservative BRI investors extend that scruple to interest income, but mainstream Protestant BRI practice today does not treat holding government-debt yield as a screen-out. Under a standard BRI product screen, USDY is not flagged.

Catholic, USCCB guidelines: the US bishops' investment framework excludes on abortion, contraception, weapons, pornography, and serious human-rights and environmental grounds. Lending at interest is not on the USCCB exclusion list. USDY passes the USCCB activity screens.

Jewish, Halakhic: this is the interesting one. The prohibition on ribbis (interest between Jews) is real and structured, and the Bais HaVaad framework distinguishes ribbis on a personal loan from returns on a properly constructed investment, and it treats interest from non-Jewish issuers differently from interest between Jews. US Treasury interest and interest from a corporate issuer like Ondo generally do not fall under the interpersonal ribbis prohibition in the way a loan between two Jews would. Many observant Jewish investors hold Treasury and money-market instruments without a heter iska, precisely because the counterparties sit outside the interpersonal ribbis rule. So USDY is broadly acceptable under a mainstream Halakhic read, with the usual advice to confirm with your posek.

LDS, Word of Wisdom and the speculation caution: the Word of Wisdom governs substances, so it is not implicated. The relevant thread is Elder Dallin H. Oaks's 1971 warning against speculation. USDY actually scores well against that caution, because it is the opposite of a speculative flyer: a low-volatility, fully-reserved, Treasury-backed instrument. Nothing in LDS financial teaching bars earning interest. Under an LDS lens, USDY is permissible and, if anything, is on the conservative end of the crypto spectrum.

So the frameworks genuinely diverge. Islam prohibits it on riba; Christian, Catholic, Jewish, and LDS screens broadly permit it. That split is not a technicality, it is the whole reason multi-faith screening exists.

The FaithScreener verdict

Under the Islamic framework, USDY is a clear no. The token is legitimate property, the reserves are real and conservative, and the depeg risk is low, but the yield is conventional interest passed straight to the holder, which is riba al-nasiah under AAOIFI standards and the Quran 2:275 to 2:279 texts. That verdict holds across holding, lending, LP, and any "staking" wrapper. Under the Christian BRI, Catholic USCCB, Jewish Halakhic, and LDS frameworks, USDY generally passes, because none of those screens exclude government-debt interest the way Islamic law does. You can pull the full breakdown and each framework's flag at faithscreener.com/crypto/USDY, browse other tokens in the crypto screener, or read how the five faith frameworks differ.

The Bottom Line

If you are a Muslim investor, USDY is off the table, and the reason is specific: you are not buying a neutral dollar token, you are buying a share of Treasury interest, which is exactly the return Islamic law prohibits. If you follow a Christian, Catholic, Jewish, or LDS framework, the interest issue does not screen it out, and USDY is one of the tamer, better-collateralized assets in crypto. The one thing to remember is that the rising price above $1.00 is the tell: that premium is interest, and whether it is permissible depends entirely on which framework you are screening under.
