Is Theo Short Duration US Treasury Fund (THBILL) Halal? Tokenized Assets and the Riba Question

Picture a token that holds its dollar peg, pays you something like 4 to 5 percent a year, settles on Ethereum, Arbitrum, Base, HyperEVM, and Stable, and never once touches a candlestick chart. That is THBILL, Theo's Short Duration US Treasury Fund. On paper it is the calmest thing in crypto. And for a faith-based investor, that calm is exactly the trap, because the whole reason the number goes up is the one reason a lot of scholars would tell you to walk away.

So is Theo Short Duration US Treasury Fund halal? The short version: the tokenization is fine, the custody is fine, the volatility is basically nil, and the yield is the problem. Let me walk through what THBILL actually is before I hand you a verdict.

What THBILL Actually Is

THBILL is a real-world-asset (RWA) token. When you mint it, Theo takes your capital and buys short-duration US Treasury bills, the sovereign IOUs the US government sells to fund itself. Those bills sit in institutional custody (Theo has named Zodia Markets on the custody side), and Theo has been folding in institutional money-market exposure too, including Fidelity International's FILQ. As those Treasuries accrue interest, that value flows back to the token, so THBILL is designed to track roughly one dollar and drift upward with the yield.

It is one of three products in Theo's line. There is thGOLD (gold exposure), thUSD (a dollar token that earns through a delta-hedged carry trade), and thBILL, the T-bill sleeve. Theo pitches the whole thing as "real-world assets, tradable and liquid," and mechanically it delivers: no lockups on the base mint, no protocol fee beyond gas, multiple audits, a transparency dashboard for attestations. As a piece of financial engineering it is clean.

Here is the part that decides everything. A Treasury bill is a loan to the government. You give the Treasury $99.50 today, they hand you $100 in three months, and that $0.50 gap is interest. Pure, contractual, time-value-of-money interest. THBILL is a wrapper that lets you own a slice of that interest stream on-chain. The token is not the issue. The cash flow inside it is.

That is the exact question at the heart of whether the Theo Short Duration US Treasury Fund is halal, and it is why an RWA token backed by T-bills lands in a completely different place than one backed by gold or physical real estate.

The Islamic Verdict: The Token Is Fine, the Yield Is Riba

Let me separate two layers, because faith screening for crypto usually collapses them and gets confused.

Layer one is the token itself: does THBILL count as legitimate wealth (mal / mutaqawwim), and is there gharar (excessive uncertainty) or maysir (gambling)? On this layer THBILL looks strong. It represents a real, custodied, identifiable asset, so it is mal with taqawwum in a way a pure meme coin never is. There is almost no gharar in the crypto-price sense, the thing is engineered to sit at a dollar. And there is zero maysir, no leverage, no bet, no counterparty coin flip. If the only question were "is this a speculative gamble," THBILL would pass cleanly. This is where the Malaysia SAC (Shariah Advisory Council) permissive approach to digital assets, which treats a token as property when it has genuine utility and backing, would have no problem recognizing THBILL as an asset.

Layer two is the cash flow, and this is where it falls apart. The yield inside THBILL is riba al-nasiah, interest on a deferred loan. This is not a close call or a matter of screening ratios. AAOIFI's 5 percent cap on interest income and its 30 percent debt-to-market-cap threshold exist to filter companies that dabble in interest at the margins. THBILL is not a company that earns a little interest on the side. Interest is the entire product. There is no 5 percent tolerance to apply when 100 percent of the return is the forbidden element. The Quran could not be more direct on this point (2:275 to 2:279), distinguishing lawful trade from riba and warning against it in the strongest terms in the whole economic law.

The Usmani and Karachi prohibitionist school, the same camp that is skeptical of most crypto, would reject THBILL not because it is a token but because it is a sovereign-interest instrument in token clothing. Shaykh Taqi Usmani's long-standing position on government bills and conventional bonds is that they are impermissible precisely because the return is contractual interest. Wrapping that in ERC-20 form changes the plumbing, not the ruling. Scholars like Mufti Faraz Adam who work on DeFi and RWA screening draw the same line: a tokenized T-bill inherits the shariah status of the T-bill, and a T-bill is riba.

Would the permissive Malaysia SAC camp save it? On the asset question, yes, they would call THBILL property. But the SAC's openness is about whether digital assets can be owned and traded, not a license for interest income. Malaysian Islamic finance runs on sukuk and murabaha structures specifically to avoid conventional interest, so even the permissive school does not bless a straight interest coupon. And scholars in the Yaquby and Amanie tradition, who sit on numerous shariah boards and have blessed genuinely structured sukuk, distinguish sharply between an asset-backed profit-and-loss instrument and a fixed interest claim. THBILL is the latter.

So the map is not "prohibitionists say no, permissives say yes." On THBILL the two camps agree on the outcome and disagree only on the reasoning. That near-consensus is rare in crypto screening, and it is worth pausing on. The doctrine (riba is haram, and Treasury interest is riba) is settled. The inference (this specific token passes that interest through to you) is straightforward once you see what backs it.

Holding vs Staking vs Lending vs LP

Because THBILL is a DeFi-native token, the activity you do with it matters, and none of the variations rescue it.

Holding THBILL is already receiving riba, since the value accrues to the token itself. This is unlike holding a plain stablecoin, where at least the base coin is inert. Here the accrual is the point.

Staking or depositing THBILL into a yield vault stacks a second problem on the first: you keep the underlying Treasury interest and add whatever the protocol pays on top, which is usually more lending yield.

Lending THBILL out, or supplying it to a money market, is textbook interest-for-interest. Two riba layers.

Providing liquidity (LP) with THBILL in a pool is murkier and depends on the pair and the fee model, but you are still parking an interest-bearing token as your inventory, so the core defect travels with it. There is no configuration where the sovereign-interest engine turns off. That is the difference between THBILL and a tokenized gold or equity RWA, where holding might be clean and only the lending layer is questionable.

Christian, Jewish, and LDS Lenses

The Islamic answer is the strictest, but THBILL is not automatically fine under the other frameworks either.

Christian BRI screening (Biblically Responsible Investing) runs on its six categories, abortion, addictions, entertainment, gambling, lifestyle, and human rights. A US Treasury bill does not obviously trip any of them, and mainstream Christian finance has never treated modest interest as sin the way classical usury doctrine once did. On a straight BRI product screen, THBILL likely passes, because its underlying is government debt, not a sin-sector company. The USCCB socially responsible guidelines work the same way, screening for exclusions like abortion, weapons, and pornography, and a Treasury bill clears those too. The catch for a thoughtful Christian investor is the older usury tradition, which many still take seriously as a matter of conscience even where the formal screens are silent.

Jewish halakhic screening is where it gets interesting, because Judaism has its own explicit interest law, ribbis. The Torah prohibits a Jew charging interest to a fellow Jew, and the Bais HaVaad and similar authorities operate a two-tier framework: interest between Jews requires a heter iska (a profit-sharing restructuring), while interest involving a non-Jewish government or borrower is generally permitted. Since THBILL's interest comes from the US Treasury, not from a fellow Jew, it does not run into the core ribbis prohibition. Under a halakhic lens THBILL is largely permissible, which is a genuine divergence from the Islamic result and a good example of why "faith-based" is not one screen but several.

The LDS (Latter-day Saint) angle is not about interest at all, it is about speculation and prudence. Elder Dallin H. Oaks's 1971 warning against speculative frenzy, and the broader Word of Wisdom-adjacent ethic of provident living, target gambling and get-rich-quick behavior. THBILL is the opposite of speculative. A dollar-pegged Treasury token is arguably one of the more prudent things in the entire crypto space. So on the LDS speculation test, THBILL passes comfortably. There is no clear LDS prohibition on earning government-bond interest.

The FaithScreener Verdict

Put the four together and you get a split that tells you everything about why single-faith screening is a category error. THBILL is largely acceptable under Jewish halakha (the interest is from a government, not a fellow Jew), it clears the formal Christian BRI and USCCB exclusions, and it passes the LDS speculation test with room to spare. Under Islamic law it fails, and it fails on the cleanest possible grounds: the entire yield is riba al-nasiah, and no screening ratio or activity tweak fixes an instrument whose sole purpose is passing through sovereign interest.

For a Muslim investor the practical guidance is simple. If you want on-chain dollar stability without the interest, look at asset-backed structures built to avoid riba (genuine sukuk, gold RWAs like thGOLD screened on their own merits, or profit-and-loss instruments) rather than a tokenized T-bill. Run the numbers yourself and see the layered reasoning at faithscreener.com/crypto/THBILL, compare it against the rest of the tokenized-asset and crypto universe, and read how each tradition scores differently on the frameworks page.

The Bottom Line

THBILL is a well-built tokenized short-duration Treasury fund, and its problem is not the wrapper, the custody, or the volatility. It is the cash flow. The yield is US government interest, which is riba al-nasiah, so THBILL is not halal under Islamic law even though it passes the Jewish, Christian, and LDS screens for different reasons. The one thing to remember: a tokenized bond inherits the ruling of the bond inside it, so before you judge any RWA token, find out whether the thing it holds pays interest or profit.
