Are index funds Halal? The 2026 Shariah Verdict for US Muslim Investors

The direct verdict

Generally, no — a conventional index fund is not Shariah-compliant. VOO, VTI, SPY, IVV, and QQQ all track indexes that hold conventional banks and insurers, and that single fact fails the screen before any ratio math begins. But this is the rare halal-finance question with a clean, drop-in fix: you don’t give up index investing, you give up the conventional index fund and buy a screened one instead. SPUS and HLAL are real, liquid US ETFs that do exactly that.

The rest of this guide runs the actual AAOIFI Standard 21 screen on a standard index fund, shows you which holdings break it, and gives you the compliant swap for each fund type — equity index, bond index, and the account wrappers (Roth IRA, 401(k), HSA) people get confused about.

The screen: AAOIFI Standard 21, in plain English

The methodology used here is the AAOIFI Shari’ah Standard 21 screen — the strictest of the common standards. It runs in two stages. A company (and therefore a fund holding it) fails if it trips any single gate.

Stage 1 — what the business does. If more than 5% of revenue comes from a non-permissible activity, it fails. That list includes conventional (interest-based) banking and insurance, alcohol, tobacco and cannabis, gambling, pork, adult content, and weapons/defense. This is the gate that kills conventional index funds.

Stage 2 — the balance sheet. Even a clean-business company has to pass three financial ratios, all measured against market capitalization:

S&P/DJIM and MSCI/FTSE Islamic indexes use a slightly looser 33% debt and cash threshold; the SPUS index uses the AAOIFI standard. Either way, the conclusion for a conventional index fund is the same.

Why a standard index fund fails — the actual holdings

Run an S&P 500 fund through Stage 1 and it fails immediately. The S&P 500 carries a Financials sector weight of roughly 13–14% (the broad US market sits near 13.6% Financial Services). Those holdings are conventional, interest-based businesses:

• JPMorgan Chase, Bank of America, Wells Fargo — conventional banks whose core revenue is net interest income.
• Berkshire Hathaway — the S&P 500’s largest financial holding; its earnings run heavily through insurance float and interest.
• Visa, Mastercard, conventional insurers — finance-sector businesses with interest-linked models.

Each one individually trips the 5% business-activity gate, and collectively they make up ~14% of the fund. A fund that holds 14% non-compliant finance cannot be Shariah-compliant. There is no purification large enough to fix a structurally non-compliant allocation — purification handles incidental interest income, not a core sector exposure.

The compliant swap: SPUS and HLAL

A screened index fund keeps the thing you actually want from index investing — broad, low-cost, diversified equity exposure — and removes the holdings that fail the screen.

SPUS — the screened S&P 500

SPUS (SP Funds S&P 500 Sharia Industry Exclusions ETF) carries a 0.45% expense ratio and is the largest US halal ETF, with about $2.07B in net assets (issuer figure, April 2026). It tracks an AAOIFI-screened version of the S&P 500 and, as of mid-2026, holds zero conventional financials. Its top weights are Nvidia (~13.3%), Apple (~11.5%), Microsoft (~7.2%), Alphabet (~5.4%), and Broadcom (~4.9%) — the screen pushes it tech- and growth-heavy because it drops the entire financial sector. Its 30-day SEC yield is 0.39%, and SP Funds publishes a quarterly purification figure.

HLAL — the screened broad US market

HLAL (Wahed FTSE USA Shariah ETF, 0.50%) tracks the FTSE Shariah USA index, screened by Yasaar Ltd, with 211 holdings (top-10 around 54%, Apple ~13.5% / Microsoft ~9.1% / Alphabet ~6.3% as of June 2026) and roughly $900M in assets. It distributes annually and publishes quarterly purification reports.

For the bond sleeve, the non-interest analogue is SPSK (Dow Jones Global Sukuk ETF, 0.50%, 30-day SEC yield 4.41%): sukuk are asset-backed certificates that pay profit from real assets, not interest. Allocated physical gold (GLDM, 0.10%) is permissible under AAOIFI Standard 57 and serves as a non-interest store of value. The longest-running active option is the Amana family — AMAGX (Amana Growth, 0.86%) and AMANX (Amana Income, 1.01%), screened since 1986 — though the higher fee is the trade-off for active management.

The wrappers: Roth IRA, 401(k), and HSA are not the issue

This is the most common confusion. A Roth IRA, Traditional IRA, 401(k), HSA, and 529 are tax wrappers, not investments. The account itself is permissible — there is nothing un-Islamic about a Roth IRA. Halal-ness depends entirely on what you hold inside it.

• Roth IRA / IRA: The account is fine. Hold SPUS, HLAL, SPSK, or an Amana fund. You can buy all of these at Fidelity, Schwab, or Vanguard — a mainstream broker is a permissible custodian; compliance depends on the holdings, not the broker.
• 401(k): The wrapper is fine, but the menu usually isn’t — most plans default to conventional index funds and target-date funds (which bundle bonds). If the plan offers a self-directed brokerage window, use it to buy SPUS/HLAL. If it doesn’t, contribute only up to any match, then route the rest to a halal IRA.
• HSA: Same logic. Once past the cash threshold, invest the balance in SPUS or HLAL rather than the default fund.

One trap inside retirement accounts: the default target-date fund. Funds like a 2050 target-date hold a bond allocation that grows as you age — those bonds are interest instruments. The wrapper is permissible; the default fund inside it usually is not.

What most people miss

Three things trip up even careful investors:

1. “Screened” does not mean “zero purification.” SPUS and HLAL still hold companies with a sliver of incidental interest income (under the 5% cap). You still owe purification — donate the attributable share of profit to charity (it is not tax-deductible). SP Funds and Wahed publish the per-share figure each quarter, so the math is done for you; you just have to act on it.
2. Holdings change every quarter. A fund that passes today can drift. Re-run the ticker through Musaffa or Zoya before a large purchase — both apply an AAOIFI-style screen to current holdings and flag any non-compliant position. This is why a static “halal list” from two years ago is unreliable.
3. The swap can be a taxable event. Selling VOO to buy SPUS in a taxable brokerage account realizes capital gains. Inside a Roth IRA or 401(k), you can switch freely with no tax. In a taxable account, weigh the long-term capital gains hit (0% / 15% / 20% depending on income) against the years of compliance ahead — often it’s worth it, but run the number first.

Crypto and gold — the gray-area footnotes

Two assets people pair with index funds deserve a note. Gold (allocated physical, via GLDM/IAU) is permissible under AAOIFI Standard 57 as a spot, allocated holding. Crypto is contested: many scholars permit spot ownership of Bitcoin or Ethereum as a non-interest asset, but staking, lending, and futures introduce interest-like returns and excessive uncertainty (gharar) that most scholars reject. That is a conditional verdict, not a flat ruling — the scholarly view is genuinely split, so treat any crypto allocation as a question for your own scholar.

The decision lever

You don’t have to choose between index investing and your faith — you have to choose the screened index fund. The lever is simple: any place you currently hold VOO, VTI, SPY, or QQQ, hold SPUS or HLAL instead. Inside a Roth IRA or 401(k), make the swap today at no tax cost. In a taxable account, model the capital gains first, then switch. For the bond portion, replace BND with SPSK sukuk or a gold sleeve. Before any large buy, re-screen the ticker on Musaffa or Zoya and set aside the quarterly purification amount the issuer publishes.

Key takeaways

• Conventional index funds (VOO, VTI, SPY, IVV, QQQ) generally fail the AAOIFI Standard 21 screen because ~13–14% of holdings are interest-based banks and insurers.
• The fix is a screened index fund: SPUS (0.45%, S&P 500) holds zero conventional financials; HLAL (0.50%) covers the broad US market.
• Bond funds (BND, AGG) fail outright as riba; the analogue is SPSK sukuk (0.50%) or allocated gold (GLDM, 0.10%).
• Roth IRA, 401(k), and HSA are wrappers — permissible accounts; halal-ness depends on the funds inside, and the default target-date fund usually holds bonds.
• Even screened funds require quarterly purification; SP Funds and Wahed publish the figure. Re-screen on Musaffa or Zoya before large buys.
