Is VOO Halal? The 2026 Shariah Verdict for US Muslim Investors

The verdict, stated plainly

VOO — the Vanguard S&P 500 ETF — is not halal. It is the single most popular index fund in America, with a 0.03% expense ratio and 505 underlying holdings, and that broad ownership is exactly why it fails Shariah screening. When you buy VOO you own a slice of every company in the S&P 500, including the conventional banks, insurers, and payment networks whose business model is lending money at interest. Interest — riba — is the bright line in Islamic finance, and VOO holds the institutions built on it.

This isn’t a gray-area call. Under the AAOIFI Shari’ah Standard 21 screen, a fund fails the moment more than 5% of its revenue comes from interest-based finance. VOO’s financials sector weight is 11.3% (verified against Vanguard’s fund profile, June 2026) — more than double the fail line, before you even run the debt-ratio and interest-income tests on the individual names. The screen returns a clean no.

The good news: there is a near-identical halal substitute. SPUS, the SP Funds S&P 500 Sharia Industry Exclusions ETF, holds the same index minus the non-compliant names — roughly 200 of the S&P 500’s 505 stocks — at a 0.45% expense ratio. You keep S&P 500-style exposure and pass the screen.

How the AAOIFI Standard 21 screen works

Shariah screening of a stock or fund runs in two stages. Stage one looks at what the business does. Stage two looks at how the balance sheet is financed. A holding has to clear both.

Stage 1 — business activity

A company (or a fund’s aggregate holdings) fails if more than 5% of revenue comes from any of these non-permissible activities:

• Conventional interest-based finance and insurance (banks, lenders, insurers)
• Alcohol, tobacco, and cannabis
• Gambling and adult entertainment
• Pork production and processing
• Weapons and conventional defense
• Conventional music, media, and entertainment

Stage 2 — financial ratios

Even a clean-business company fails if its balance sheet is too leveraged or too dependent on interest. Under the strict AAOIFI thresholds:

(Less strict index methodologies — S&P/DJIM and MSCI/FTSE Islamic — use a 33% debt limit measured against total assets, which is why a name can pass one screener and fail another. AAOIFI is the strictest, and the one we apply here.)

Running the screen on VOO’s actual holdings

VOO replicates the S&P 500 exactly. Here is what the fund looks like in June 2026, pulled from Vanguard’s own fund profile:

The 11.3% financials sleeve is the disqualifier. It includes JPMorgan Chase, Bank of America, Wells Fargo, Berkshire Hathaway (an insurance and lending conglomerate), Visa, and Mastercard. Their revenue is interest spread, lending, and conventional insurance float — squarely the activity AAOIFI fails at the 5% line. A fund holding all of them, at 11.3% of assets, cannot pass Stage 1.

Stage 2 piles on. Across the S&P 500 you also hold dozens of capital-intensive names — utilities, telecoms, airlines, REITs — carrying interest-bearing debt above 30% of market cap. Even names with clean business activity (an airline, a heavily levered industrial) breach the debt ratio individually. VOO makes no attempt to screen any of this out; that is the entire point of a low-cost total-index fund. It is built to own everything, and “everything” includes the non-compliant.

The halal replacement: SPUS, HLAL, and the active funds

You do not have to abandon large-cap US equity to stay compliant. There is a purpose-built screened version of nearly every exposure VOO gives you.

For a direct VOO swap, SPUS is the closest match. It tracks the S&P 500 Shariah Index — the same parent index, with the financials and ratio-failers removed — leaving roughly 200 compliant constituents. Because the screened-out sleeve is mostly finance, what remains skews even more toward technology than VOO already does. SP Funds also publishes a quarterly purification calculator so you can clean any incidental interest income.

Prefer active management or a longer track record? The Amana funds from Saturna Capital have run on Islamic principles since 1986. AMAGX (growth) and AMANX (income) carry higher fees — 0.86% and 1.01% respectively — because a manager, not an index, makes the calls. That is the trade-off: longer pedigree and human screening for roughly double SPUS’s expense ratio.

What most people miss

Three misconceptions send Muslim investors into the wrong fund. Clear these and the decision gets simple.

1. “I’ll just purify the haram part”

Purification — donating the share of profit traceable to impermissible income — is real and required, but it only applies to incidental interest income inside an otherwise-compliant holding. It does not rescue a fund that fails the business-activity screen. VOO doesn’t earn a little stray interest; it directly owns conventional banks. The ownership itself is the problem, not just the income. Purification is the cleanup step after you’re in a screened fund — it is not a license to hold a non-compliant one.

2. “The fee gap makes the halal fund a bad deal”

VOO charges 0.03%; SPUS charges 0.45%. That 0.42-point gap sounds large in percentage terms but is $42 a year on a $10,000 position. For a religiously observant investor, the comparison isn’t SPUS vs VOO on fee alone — VOO is off the table entirely. The real comparison is SPUS (0.45%) vs HLAL (0.50%) vs the Amana funds (0.86%–1.01%), and on that axis SPUS is the cheapest screened S&P 500 vehicle available.

3. “The account type determines whether it’s halal”

A Roth IRA, Traditional IRA, 401(k), HSA, or 529 is a tax wrapper, not an investment. The wrapper is permissible. Halal-ness depends entirely on what you put inside it. VOO is non-compliant whether it sits in a taxable brokerage account or a Roth IRA. Inside a Roth, you simply buy SPUS or HLAL instead. The one real friction is a 401(k) with no Shariah-compliant option — there, use a self-directed brokerage window if the plan offers one, or direct new contributions to an IRA where you control the holdings.

The interest-product trap nearby

Muslim investors who correctly ditch VOO sometimes land in something worse: an interest product dressed up as “safe.” For the record, none of these are compliant, because each pays riba directly:

• High-yield savings accounts, CDs, money-market funds — the yield is interest. Compliant cash analogues: a Wahed sukuk/cash sleeve, a profit-sharing account at an Islamic institution, or allocated physical gold (GLDM, 0.10%).
• Treasuries, T-bills, I-Bonds, corporate and muni bonds — all interest instruments. The halal “bond” analogue is SPSK (SP Funds Dow Jones Global Sukuk ETF, 0.50%), which holds sukuk — asset-backed certificates that pay rent or profit-share, not interest.
• Default target-date funds in a 401(k) — these blend bonds and conventional equities and will fail the screen on both counts. This is the most common accidental violation, because target-date funds are usually the plan default.

The decision lever

VOO fails the screen on a single decisive number: 11.3% conventional financials against a 5% AAOIFI fail line. There is no version of the math where it passes, and no purification workaround that fixes ownership of conventional banks. The move is mechanical: sell or stop buying VOO, buy SPUS for the closest screened S&P 500 exposure (or HLAL for broader-market, or the Amana funds if you want active management), set a calendar reminder to run the quarterly purification calculator, and hold compliant cash analogues (sukuk via SPSK, or allocated gold) instead of HYSAs and Treasuries. That sequence keeps you in large-cap US equity and inside the screen at the same time.

Key takeaways

• VOO is not halal. Its 11.3% financials weight (Vanguard profile, June 2026) breaches the AAOIFI Standard 21 business-activity screen, which fails any fund with more than 5% interest-based finance revenue.
• The same ruling applies to SPY and IVV — they track the identical S&P 500 index in full.
• SPUS (0.45%) is the closest halal replacement: the S&P 500 Shariah Index, ~200 screened names. HLAL (0.50%) is the broad-market option; AMAGX/AMANX are the active funds.
• Purification cleans incidental interest income inside a compliant fund — it does not make VOO permissible.
• Account wrappers (Roth IRA, 401(k), HSA) are permissible; only the holdings inside them are screened.
• Interest products — HYSAs, CDs, Treasuries, bonds, default target-date funds — are non-compliant; use SPSK (sukuk) or allocated gold instead.
