Is Securitize Tokenized AAA CLO Fund (STAC) Halal? Tokenized Assets and the Riba Question

Grove Finance parked $100 million into a token, Ethena Labs earmarked another $250 million, and the thing they were buying is a blockchain wrapper around one of the most interest-heavy instruments in all of structured credit. The token is STAC, the Securitize Tokenized AAA CLO Fund, and the moment you understand what actually sits underneath it, the halal question mostly answers itself. This is not a hard case. It just looks like one because "tokenized real-world asset" sounds modern and clean, while "collateralized loan obligation" sounds like something a bank does.

So let's be precise about what you're actually holding, because the answer to "is Securitize Tokenized AAA CLO Fund halal" turns entirely on the plumbing, not the packaging.

What STAC actually is

STAC is a tokenized fund launched by Securitize that, in the fund's own language, aims to invest substantially all of its assets in U.S. dollar-denominated, AAA-rated CLO tranches from both the primary and secondary markets. Securitize runs the platform, onboarding, and recordkeeping. BNY provides custody and fund administration. It went live on Ethereum in October 2025 and expanded to Solana in June 2026, so the token now moves across two chains while the assets sit in a regulated fund structure off-chain.

Now the part that matters. A CLO, a collateralized loan obligation, is a pool of leveraged corporate loans, mostly senior secured bank loans made to below-investment-grade companies. Those loans throw off interest payments every quarter. The CLO slices that cash flow into tranches ranked by seniority. The AAA tranche sits at the very top of the waterfall. It gets paid first, it absorbs losses last, and its entire economic return is interest income skimmed off the top of a giant pile of corporate debt.

So STAC is a token whose yield is, definitionally, the interest paid by hundreds of borrowers on loans they took out. Strip away the ERC-20 and the Solana bridge and you have a claim on a stream of loan interest. That is the whole product. On FaithScreener this lands in the real-world asset (RWA) class, and the RWA label is exactly where people get tripped up, because "backed by a real asset" is treated as a virtue when the real asset in question is a debt instrument.

The Islamic verdict: this is riba, plainly

Here is where the tokenization crowd and the fiqh part ways hard.

Money value (mal) and legal ownership (taqawwum) are not the problem with STAC. You genuinely own a share of a real, regulated fund holding real securities. Gharar, excessive uncertainty, is also not the core issue. AAA CLO tranches are about as low-volatility and predictable as structured credit gets, which is precisely the selling point Securitize leans on. And maysir, gambling, is not really present either, because you are not speculating on a coin flip. You are clipping a coupon.

The coupon is the problem. That coupon is interest, riba al-nasiah, the increase paid on a loan of money over time. The Quran could not be more direct about it: "Allah has permitted trade and forbidden riba" (2:275), followed by the warning of war from Allah and His Messenger against those who do not abandon it (2:278 to 279). STAC's yield is not rent on an asset you lease out. It is not profit from a genuine trade or a partnership where you share downside. It is a fixed, senior, contractual claim on borrowers' interest payments. That is the textbook definition of the thing that is prohibited.

This is worth stressing because the two big schools of contemporary crypto fiqh usually disagree, and here they don't. The prohibitionist camp associated with Mufti Taqi Usmani and the Darul Uloom Karachi position has long been skeptical of much of crypto on grounds of gharar, lack of intrinsic value, and speculation. The more permissive Malaysian view, expressed through the Securities Commission's Shariah Advisory Council (SAC), has ruled that digital assets can be treated as recognized property (mal) and traded, subject to activity screening. That is a real and meaningful split when you're arguing about Bitcoin or a governance token.

STAC collapses the split. The Karachi school rejects it for the obvious reason. But even the permissive Malaysian framework, which is happy to call a token mal and let you trade it, still applies an activity screen, and the activity here is lending money at interest. There is no reading of the SAC's own methodology that clears a fund whose sole purpose is to earn interest on corporate loans. Scholars who work on structured products, including figures like Sheikh Nizam Yaquby and the Amanie advisory practice, have consistently held that conventional interest-bearing debt securities are non-compliant regardless of wrapper. Tokenizing a bond does not make the bond halal. Tokenizing a CLO does not make the interest stop being interest.

So this is doctrine, not inference. The prohibition of riba is a clear ruling grounded in explicit text, and STAC's return is riba by construction. There is no scholarly disagreement to map here, because no recognized Shariah board treats senior interest income as permissible.

Holding vs staking vs lending vs LP

For a lot of tokens this section is where the nuance lives, because holding a coin can be fine while lending it out for a fixed return crosses into riba. With STAC the base layer is already the problem, so the activity split mostly compounds it rather than rescuing it.

Holding STAC is holding a claim on interest income. Non-compliant at rest.

Staking, in the SRB and broader staking taxonomy, ranges from validator rewards (often treated as a service fee, potentially permissible) to lending-style yield (not permissible). STAC is not a proof-of-stake network asset, so there is no protocol staking that would apply here in the first place.

Lending STAC into a money market or using it as collateral to borrow against, which is exactly what protocols like Grove and Ethena are building around it, layers a second interest relationship on top of the first. Now you have interest on interest.

Providing liquidity (LP) with STAC in a DeFi pool means facilitating the trading of an interest instrument and often earning fees plus exposure to the token's yield. You are helping other people transact in the riba product and taking a cut. That does not fix anything.

There is no activity in the STAC stack that turns it compliant, because the impurity is in the cash flow itself, not in what you do with the token afterward.

The other three lenses

STAC is a genuinely interesting case for a multi-faith screen, because the frameworks split on it more than you might expect.

Christian (BRI and USCCB). The Biblically Responsible Investing framework screens companies across roughly six moral categories, things like abortion, pornography, and other activities the underlying business is engaged in. The USCCB guidelines exclude on similar moral grounds. Neither framework treats interest itself as disqualifying. Christian usury prohibitions, once strict, were largely relaxed over centuries, and modern Christian screening is about what a company does, not whether it earns interest. So STAC does not fail on the classic BRI or USCCB triggers. The honest caveat is that you cannot see through a CLO to the individual borrowers, so you cannot rule out that some of the underlying leveraged loans financed excluded industries. On the framework's own terms, though, an AAA CLO fund is not a moral-screen failure. Call it permissible with a look-through caveat.

Jewish (Bais HaVaad, two-tier ribbis). Halakha operates a two-tier interest prohibition: a biblical ban on ribbis between Jews and a broader rabbinic layer, with the heter iska structure used to convert a loan into a permissible profit-and-loss venture. The critical point is that the ribbis prohibition governs interest between Jews. STAC's underlying borrowers are hundreds of anonymous, mostly non-Jewish corporations, and the fund is an intermediated pooled vehicle. Bais HaVaad's analyses of pooled and intermediated instruments generally do not treat impersonal corporate-debt exposure through a fund as triggering the personal ribbis prohibition. So for a Jewish investor, STAC is far less problematic than it is for a Muslim one. Broadly permissible, with heter iska concerns only arising in direct Jew-to-Jew lending, which is not what this is.

LDS (Word of Wisdom and the Oaks speculation warning). The Word of Wisdom is a dietary and health code, so it is simply not on point for a financial instrument. The relevant guidance is Elder Dallin H. Oaks' 1971 warning against speculation and the counsel, repeated across LDS teaching, to avoid debt and get-rich-quick schemes. STAC is almost the anti-speculation asset: AAA-rated, income-oriented, low volatility, boring by design. There is no doctrinal LDS bar to holding it. If anything it fits the "conservative and prudent" temperament the Church encourages, and the only soft caution is the general LDS wariness of complex debt-based financial products. Permissible.

So the same token is clearly forbidden under one framework and broadly fine under three others. That divergence is the whole reason to screen by your actual tradition instead of assuming "responsible investing" means the same thing everywhere. You can compare all five lenses side by side on the frameworks page.

The FaithScreener verdict

For an Islamic screen, STAC is not compliant. The token's entire economic return is interest on corporate debt, which is riba al-nasiah, prohibited by explicit Quranic text and rejected by every mainstream Shariah authority regardless of how it is wrapped. Tokenization changes the settlement rail, not the ruling. Neither the Karachi prohibitionist school nor the permissive Malaysian SAC framework has any path to clearing a pure interest-income fund, so this is one of the rare crypto assets where the usual scholarly debate never even gets started.

Under the Christian, Jewish, and LDS frameworks the picture flips to broadly permissible, for the reasons above, with the main caveat being that you cannot see through the CLO to the individual borrowers.

The Bottom Line

STAC is a well-built, low-risk, thoroughly regulated way to earn interest on leveraged corporate loans, and that last clause is exactly why it fails an Islamic screen: the yield is riba, full stop, and no amount of tokenization launders it. Christian, Jewish, and LDS investors have real room to hold it; a Muslim investor does not. The one thing to remember is that "backed by a real-world asset" tells you nothing about compliance when the real-world asset is a debt instrument, so always screen for the cash flow, not the label.
