Is Spiko Amundi Overnight Swap Fund (SAFO) Halal? Tokenized Assets and the Riba Question

The name gives the whole thing away, and most people scroll right past it. "Overnight Swap Fund." Not "T-bill fund," not "gold fund," not "real estate fund." The word doing the heavy lifting is swap, and once you understand what that swap actually does, the question of whether SAFO is halal stops being about blockchains and starts being about a 1,400-year-old prohibition on lending money at a fixed return.

So let me walk you through what Spiko built here, because it is genuinely clever financial engineering, and then why that same cleverness is exactly what a Shariah screen flags first. The short version of "is Spiko Amundi Overnight Swap Fund halal" is: almost certainly not, and for a reason that has nothing to do with it being a token.

What SAFO Actually Is

Spiko is a European fintech that tokenizes regulated money market funds. Their first two products were straightforward: a euro T-bill fund (EUTBL) and a US T-bill fund (USTBL), both holding actual short-dated government paper. You buy a token, the token is a share in the fund, the fund holds treasuries, and the yield flows to you as the token's net asset value climbs.

SAFO is a different animal. It is built in collaboration with Amundi, Europe's largest asset manager, and it is structured as a tokenized UCITS fund domiciled in France. The token itself is distributed across several chains, including Stellar, Ethereum, Arbitrum, Polygon, and Base, so you can hold it in an ordinary wallet and it trades right around $1 of NAV, accumulating value rather than paying a coupon. Recently it has tracked the overnight benchmark rate, landing in roughly the high-3% range on a trailing basis, with a management fee around 0.25%. On the surface it looks like every other real-world-asset (RWA) stablecoin-yield product now flooding the market.

Here is the part that matters. SAFO does not earn its yield by holding treasuries and clipping the interest directly. It holds a collateral basket of securities and then enters fully collateralized total return swaps with large bank counterparties. In plain terms: the fund hands over the total return of its securities basket and receives, in exchange, the overnight interest rate plus a spread, reset daily. The "overnight swap" in the name is a synthetic replication of an overnight cash-deposit return, manufactured through a derivative.

That structure is the entire ballgame for a faith screen. Hold that thought.

The Riba Question: Islamic Verdict

Islamic finance does not object to tokens, blockchains, or even to earning a return on money that is genuinely put to work. What it prohibits is riba: a stipulated, guaranteed increase on a loan of money or a like-for-like exchange. The Quran is direct about it in 2:275 through 2:279, drawing a hard line between trade, which is permitted, and riba, which is not. The whole discipline of Shariah screening exists to figure out which side of that line a given instrument sits on.

A tokenized T-bill fund like Spiko's EUTBL already has a well-known problem: a government treasury bill is a loan to the state that pays fixed interest, which is riba al-nasiah, the interest-on-deferred-payment kind. Most scholars treat conventional T-bill exposure as impermissible for exactly that reason, which is why sukuk (asset-backed certificates that pay rent or profit share) exist as the halal alternative.

SAFO manages to be a step further removed from anything permissible. Its return is not even rent or trade profit dressed up. It is the overnight interbank interest rate, delivered through a total return swap. Two problems stack on top of each other here:

First, the reference rate itself. Receiving "overnight rate plus spread" is receiving interest by definition. It is the price of money over time, guaranteed and stipulated, which is the textbook description of riba. The fact that a securities basket sits behind it as collateral does not change what you are being paid. You are being paid interest.

Second, the swap. Total return swaps are derivatives, and the mainstream position across AAOIFI-aligned scholarship is that conventional swaps involve gharar (excessive uncertainty) and frequently maysir (speculation), plus the exchange of two future obligations without a real underlying sale. AAOIFI's screening framework caps a company's interest-based income at 5% of revenue and its interest-bearing debt and securities at roughly 30 to 33% of market cap. SAFO does not squeak in under those caps. Interest-linked swap income is not a rounding error in its revenue; it is 100% of the point of the fund.

On crypto specifically, scholars genuinely disagree, and it is worth being honest about that split. The prohibitionist camp associated with Mufti Taqi Usmani and the Karachi tradition argues most crypto lacks intrinsic value (mal and taqawwum, recognized property with lawful value) and is riddled with speculation. The more permissive camp, reflected in Malaysia's Securities Commission Shariah Advisory Council, has ruled that digital assets can qualify as recognized property and be traded. Scholars like Sheikh Yaquby and the Amanie board have taken case-by-case views on tokenized instruments.

But notice: that debate is about whether a token can be property at all. SAFO clears that bar easily. It is a regulated fund share, so it is unambiguously mal. The token wrapper is the least of its problems. Even the permissive Malaysian-style reading, which would happily accept a well-structured tokenized sukuk, gives you no cover here, because the thing being tokenized is an interest swap. A halal wrapper around a riba engine is still riba. That is inference built directly on the doctrine of 2:275, and it is not a close call.

Holding vs Staking vs Lending vs LP

Because SAFO is a yield-bearing fund token, the activity layer does not save it either, but it is worth mapping.

Holding: You hold the token, its NAV rises as the swap pays out. You are the direct recipient of interest income. This is the core problem, not a mitigation of it.

Staking: SAFO is not a proof-of-stake network asset, so there is no protocol staking in the validator sense. Any "stake for extra yield" program layered on top would just add a second interest stream on top of the first.

Lending: Deposit SAFO into a lending market and you earn a borrow rate on top of the fund's own interest yield. That is riba compounded on riba.

Liquidity providing: Pool SAFO against a stablecoin on a DEX and you collect trading fees, which in isolation can be a permissible service. But you are still holding and providing an interest instrument, and impermissibility of the underlying carries through. You cannot LP your way clean.

There is no configuration of SAFO where the money you make is rent, trade profit, or a share in real enterprise risk. Every path routes back to the overnight rate.

Christian, Jewish, and LDS Verdicts

The Islamic screen is the strictest here, but SAFO does not fare much better under the other frameworks, which is unusual.

Christian BRI and Catholic USCCB: Faith-based investing screens like the biblically responsible investing (BRI) approach and the USCCB's socially responsible guidelines are built mainly around product-based exclusions, abortion, pornography, weapons, tobacco, predatory lending. A pure interest-yield fund is not on the classic exclusion list, and modern Christian ethics generally permits ordinary interest. So under BRI's six standard categories and USCCB's exclusion framework, SAFO's yield mechanism itself is not disqualifying. The relevant question shifts to the collateral basket: what securities does the swap reference, and do any of them violate the exclusions? Without transparency into that basket you cannot fully clear it, so the honest verdict is "not obviously excluded, but unverifiable on look-through."

Jewish Halakhic (Bais HaVaad): Jewish law prohibits ribbis (interest) between Jews, and the Bais HaVaad's guidance operates a practical two-tier system: interest from a clearly gentile-owned or non-Jewish corporate entity is generally permitted, while interest arrangements between Jews require a heter iska, the profit-sharing workaround that recharacterizes a loan as a joint venture. SAFO is a French corporate fund paying a market rate through bank counterparties, so for most investors it would fall on the permitted side, no heter iska needed. The halakhic verdict is closer to acceptable than the Islamic one.

LDS (Word of Wisdom and Oaks on speculation): The Word of Wisdom governs consumption, not securities, so it is silent here. The relevant LDS teaching is Elder Dallin H. Oaks's 1971 warning against speculation, the counsel to avoid get-rich schemes and gambling-like risk-taking. Ironically, a low-volatility overnight-rate fund is the opposite of speculative; it is about as boring as a token gets. So on the speculation axis, SAFO passes an LDS gut-check cleanly. There is no prohibition in LDS teaching on earning interest.

So you get a genuinely split verdict across faiths: impermissible under Islam, largely permissible under Jewish and LDS lenses, and conditionally-clear under Christian screens pending basket disclosure. That divergence is the whole reason multi-framework screening exists, and you can compare the logic side by side on the frameworks page.

The FaithScreener Verdict

Under the Islamic lens, SAFO screens as non-compliant, and it is not a marginal 32%-debt-ratio miss you might waive. The fund's defining feature, an overnight total return swap that pays the interest rate, is riba at the level of doctrine, not inference. Tokenization, chain, and NAV mechanics are irrelevant to that conclusion. If you want a halal way to park cash on-chain, the structurally correct instrument is a tokenized sukuk or an equity-based fund that shares real profit and loss, not a synthetic interest wrapper.

You can pull the current status, the underlying-asset classification, and the per-activity breakdown for holding, lending, and LP yourself. Check SAFO live on FaithScreener, and if you are weighing it against other RWA and stablecoin-yield tokens, the full crypto screening list runs the same layered test across 3,300-plus assets so you can see which yield products are genuinely asset-backed versus interest-synthetic.

The Bottom Line

SAFO is a well-built, regulated, low-risk tokenized fund, and under Islamic screening it still fails, because its entire yield is manufactured interest delivered through a total return swap. The one thing to remember: the "swap" in Overnight Swap Fund is not a technical detail, it is the riba, and no blockchain wrapper cleans it. Jewish and LDS frameworks land closer to permissible, and Christian screens hinge on the undisclosed collateral basket, but for a Muslim investor this one is a clear no.
