Is This ETF Halal? The 4-Filter Methodology to Screen Any Fund Yourself

Why “halal ETF” is not a regulated label

There is no SEC designation, FINRA category, or legal standard called “halal.” Unlike “ESG” (which at least has reporting frameworks), Shariah compliance in the US investment market is entirely a function of private-sector screening by Islamic finance scholars. An ETF is halal if a recognized Shariah advisory board certifies that its screening methodology meets Islamic law standards — and it stays halal only as long as the board monitors ongoing compliance.

That means you cannot rely on a fund name or marketing copy. You need to verify: (1) does this fund track a Shariah-screened index? (2) who is the Shariah advisory board? (3) what screening methodology do they apply? The four-filter framework below is what every major board uses, with minor threshold variations.

The 4-filter methodology: what every Shariah board checks

Every mainstream Shariah screening standard — AAOIFI (Accounting and Auditing Organization for Islamic Financial Institutions), the S&P Dow Jones Shariah methodology, the FTSE Russell Shariah methodology, and the DJIM (Dow Jones Islamic Market) methodology — applies the same four-category framework. The thresholds differ slightly between boards. Here is the full picture:

Filter 1: Business-activity screen (qualitative)

A company fails immediately if its primary business involves any of these activities:

• Conventional finance — banks, insurance companies, and lenders whose core business is interest-based (riba)
• Alcohol — production, distribution, or sale as a primary revenue source
• Gambling — casinos, sports betting, lottery operations
• Pork — production, processing, or sale
• Adult entertainment
• Weapons and defense — most boards exclude manufacturers of conventional weapons; some extend this to defense contractors and dual-use aerospace
• Tobacco — most major boards now exclude this; some older standards did not

The threshold question: what if a company earns 3% of revenue from alcohol (like a grocery chain that sells beer)? Most boards set a 5% non-compliant revenue tolerance — meaning a company can derive up to 5% of revenue from a prohibited activity and still pass Filter 1. Above 5%, it fails. This is why large diversified retailers like Costco or Walmart can pass the business-activity screen even though they sell some non-compliant products — those categories are a small fraction of total revenue.

Filter 2: Debt-to-market-cap (or debt-to-total-assets) ratio

A company that passes Filter 1 must then pass three financial-ratio screens. The first checks how much interest-bearing debt the company carries.

Filter 3: Interest-income (or non-permissible income) ratio

Even a company with compliant business operations may earn interest on its cash reserves, short-term investments, or financing arrangements. This filter checks how much of that income comes from non-permissible sources.

• AAOIFI: non-permissible income ÷ total revenue < 5%
• S&P / FTSE / DJIM: (cash + interest-bearing securities) ÷ market cap < 33.33%

Notice the approaches differ. AAOIFI measures non-permissible income as a share of revenue — a direct income-statement check. The index-provider methodologies measure the balance of interest-bearing assets relative to market cap — a balance-sheet check. Both aim to limit riba exposure, but through different lenses. The AAOIFI approach is stricter for companies with small cash balances but high interest yields; the market-cap approach is stricter for companies hoarding large cash piles.

Filter 4: Accounts receivable and liquid assets ratio

This filter addresses a subtler concern: if a company’s value is primarily in cash and receivables (rather than real assets, inventory, or intellectual property), trading its shares starts to resemble trading debt — which is prohibited. The thresholds:

• AAOIFI: (accounts receivable + cash) ÷ total assets < 33% (some AAOIFI scholars use a stricter 49% for receivables alone, separate from cash)
• S&P Shariah: accounts receivable ÷ market cap < 49%
• FTSE Shariah: (cash + accounts receivable) ÷ market cap < 50%
• DJIM: (accounts receivable + cash) ÷ market cap < 33%

The bottom line on threshold variation: if a company’s ratios are comfortably below 30% on all three financial filters, it passes every major standard. If it is in the 30–33% range, the choice of standard matters. If it is above 33%, it fails every standard.

Worked example: screening Apple (AAPL) through all 4 filters

Apple is one of the most widely held stocks globally and appears in the top 5 holdings of both SPUS and HLAL. Here is how it screens (using approximate figures from Apple’s most recent annual filing):

Apple passes all four filters comfortably under every major Shariah standard. Its enormous market capitalization makes the financial ratios trivially small. This is typical of mega-cap tech companies — which is why halal ETFs are so heavily concentrated in technology.

Worked example: screening JPMorgan Chase (JPM) through all 4 filters

JPMorgan is the largest US bank by assets. It appears in the S&P 500 but in neither SPUS nor HLAL. Here is why:

JPMorgan fails at Filter 1. You do not even reach the financial ratios. A conventional bank’s core business model — taking deposits and lending at interest — is fundamentally non-compliant. The same applies to Bank of America, Wells Fargo, Citigroup, Goldman Sachs, and every other conventional bank or insurance company. This single filter is why halal ETFs hold 0% financials.

How to screen an ETF you already own (or want to buy)

For a pre-certified halal ETF like SPUS or HLAL, the screening is done for you. But what if you are evaluating an ETF that is not marketed as halal — like a sector fund in your 401(k), or a thematic ETF you are interested in? Here is the practical process:

1. Pull the ETF’s full holdings list. Every ETF issuer publishes this on their website (iShares, Vanguard, State Street, etc.). Download the CSV or view the top 25 holdings at minimum.
2. Run Filter 1 on the entire list. Scan for any company whose primary business is banking, insurance, alcohol, gambling, pork, weapons, or adult entertainment. If the ETF holds JPMorgan, Bank of America, Anheuser-Busch, or Las Vegas Sands — it is not halal as-is.
3. For borderline holdings, run Filters 2–4. Use a screening tool like Zoya (zoya.finance), Islamicly, or Musaffa to check individual stocks. These apps pull financial data and calculate the ratios for you against the AAOIFI standard. You can also do it manually from the company’s 10-K filing: pull total debt, total cash, accounts receivable, total assets, and market cap, then compare to the thresholds in the tables above.
4. Calculate the non-compliant weight. If 5% of the ETF’s assets are in non-compliant holdings, some scholars permit holding the fund with purification of that portion’s income. If 20%+ is non-compliant, the fund is not viable for a halal investor — find an alternative.

The tool shortcut: what Zoya and similar apps actually do

Zoya (the most widely used Shariah screening app for US investors) automates Filters 1 through 4 for individual stocks. You search a ticker, and Zoya pulls the company’s financial data, runs it against AAOIFI-aligned thresholds, and gives you a compliant / non-compliant / questionable verdict with the underlying ratios visible.

What Zoya does not do: screen an entire ETF as a single unit. You cannot type “SPUS” into Zoya and get a fund-level compliance verdict. For ETFs, you are relying on the fund’s Shariah advisory board (if it has one) or manually spot-checking holdings. Musaffa offers a fund-screening feature that checks holdings in aggregate — worth using if you want a second opinion on a fund your advisor recommends.

Edge cases that trip up DIY screeners

The four filters are straightforward in concept but have real edge cases:

• Market-cap volatility. A stock that passes the 33% debt-to-market-cap threshold in January can fail it in March after a 40% stock-price drop — without the company borrowing any additional money. This is why index-provider methodologies use trailing average market cap (24 or 36 months) rather than spot price.
• Conglomerate classification. A company like Amazon earns revenue from e-commerce (compliant), cloud computing (compliant), and a small financial-services unit (Amazon Lending, Amazon Pay). Whether it passes Filter 1 depends on whether the financial-services revenue exceeds 5% of total revenue. As of 2026, it does not — but the line moves.
• REITs and real estate. Real estate investment trusts typically carry high debt ratios (many exceed 33% debt-to-total-assets). Most REITs fail Filter 2. Some Shariah scholars permit equity REITs with moderate leverage under specific conditions, but this is not consensus — check with your own advisor.
• Pharmaceutical companies. Most drug manufacturers pass all four filters. The debate among some scholars is whether companies producing alcohol-based medications or medical products derived from pork violate Filter 1. The mainstream position is that pharmaceutical use falls under medical necessity (darurah) and does not disqualify the stock, but this is not unanimous.

What “Shariah-certified ETF” actually means — and what to verify

When an ETF says it is Shariah-compliant, verify three things before investing:

1. Named Shariah advisory board. The fund should disclose its Shariah advisor by name (e.g., Ratings Intelligence for SPUS, Yasaar for HLAL). If no board is named, treat the “halal” label with skepticism.
2. Published methodology. The screening rules (which filters, which thresholds, which denominator) should be public. Both S&P and FTSE publish their Shariah index methodologies online.
3. Rebalancing schedule. The fund should remove non-compliant holdings at regular intervals (quarterly or semi-annually). A fund that screens once at launch and never again is not maintaining compliance.

The bottom line

No ETF is inherently halal or haram. Shariah compliance is a structural property of the screening process, and it is something you can verify yourself. The four filters — business-activity exclusion, debt ratio, interest-income ratio, and receivables ratio — are the same framework that every major Shariah board applies. The thresholds vary slightly (30% vs. 33% on debt, 33% vs. 49% on receivables), but the framework is universal.

For pre-certified halal ETFs like SPUS and HLAL, trust the process but verify the board. For non-certified ETFs, use the four-filter methodology to screen the largest holdings yourself, or use tools like Zoya to automate the stock-level check. If more than 5% of the fund’s assets are in clearly non-compliant holdings, look elsewhere.

The goal is not perfection — no screening methodology catches every edge case, and scholars disagree on thresholds for good reasons. The goal is a systematic, repeatable process that keeps your portfolio within the bounds of mainstream Shariah compliance and gives you the confidence to evaluate any fund, not just the ones with “halal” in the name.
