iShares MSCI World Islamic UCITS ETF (ISDW): The Global Halal Play

Here's a fund that almost nobody in the US talks about because they can't buy it, but it deserves to be understood because if you're a Muslim investor anywhere outside the US, it's probably the best single-fund global equity solution available.

ISDW is the iShares MSCI World Islamic UCITS ETF. It trades on the London Stock Exchange, Borsa Italiana, and Deutsche Borse. It's domiciled in Ireland. It's run by BlackRock. And it gives you roughly 280 companies spanning 20-plus developed market countries in one ticker.

Let's actually dig in.

What ISDW Tracks

The fund tracks the MSCI World Islamic Index, which is MSCI's Shariah-compliant version of the MSCI World. MSCI World covers large and mid-cap stocks from 23 developed markets, including the US, Japan, UK, France, Germany, Canada, Australia, Switzerland, and more.

MSCI applies its Islamic screening methodology to this base universe. The business screens are the standard set: no conventional financial services, no alcohol, no pork, no tobacco, no weapons, no gambling, no adult entertainment, no interest-based hotels. The financial screens use the "33 percent rule" in a specific form: total debt over total assets below 33.33 percent, cash plus interest-bearing securities over total assets below 33.33 percent, and accounts receivable over total assets below 33.33 percent.

Companies that pass all the screens make the index. MSCI rebalances twice a year (May and November) with quarterly reviews for extraordinary changes.

The Actual Portfolio

ISDW holds around 280 to 310 names depending on the rebalance cycle. That's significantly more diversification than SPUS (about 210 holdings) or HLAL (about 200 holdings).

Country breakdown typically looks like: 60 to 65 percent US, 7 to 9 percent Japan, 5 to 7 percent UK, 4 to 5 percent France, 3 to 4 percent Germany, 3 to 4 percent Canada, 2 to 3 percent Switzerland, and smaller allocations to Australia, Netherlands, Sweden, and the rest. The US weight is still dominant because that's how global market-cap indexes work, but you get meaningful international exposure on top.

Sector breakdown: roughly 32 to 38 percent technology, 18 to 22 percent healthcare, 10 to 13 percent industrials, 9 to 12 percent consumer discretionary, 6 to 8 percent communication services, plus smaller slices in materials, energy, and consumer staples.

Top holdings usually include Apple, Microsoft, Nvidia, Alphabet, Meta, Eli Lilly, Tesla, Broadcom, ASML, and Toyota. Notice the inclusion of international names like ASML (Dutch semiconductor equipment) and Toyota (Japanese auto), which you don't get in pure US halal funds.

Expense Ratio: 0.30 Percent

ISDW charges 0.30 percent per year. That's significantly cheaper than SPUS (0.49) or HLAL (0.50). Why? Because BlackRock has scale. The iShares Islamic range has been around in various forms since 2007, and BlackRock is not running ISDW as a passion project. It's a product line that benefits from shared infrastructure with the rest of iShares.

This 0.30 percent is easily the lowest expense ratio you'll find on any reasonably-sized halal equity ETF anywhere in the world. For European and Middle Eastern investors who can actually buy it, that's a real win.

Over a 20-year holding period, the difference between 0.30 and 0.50 on a 100,000 euro portfolio is roughly 7,000 euros in fees. Not trivial.

AUM: Around 600 to 700 Million USD

ISDW is smaller in USD terms than SPUS but still plenty liquid. As of early 2026, it's running around 600 to 700 million dollars in assets. The fund has been growing steadily as ESG-adjacent European investors and Gulf-based wealth managers use it as a core allocation.

Trading liquidity is decent on the London Stock Exchange. Daily volume is moderate (not SPUS-level, but sufficient for retail investors). Bid-ask spreads widen during off-hours when you have the London exchange closed and US markets are driving prices, so buying during European trading hours gives you tighter fills.

Can US Investors Buy It?

Short answer: no, not directly. US brokerages won't let retail clients buy UCITS ETFs because of PRIIPs regulations and the KID disclosure requirement. US investors who want global halal exposure have to use a mix of SPUS for US and something like UMMA or Amana Developing World for international.

This is genuinely annoying. ISDW is arguably the best-built halal equity ETF on the planet and American investors are locked out because of cross-border fund regulation.

Performance Estimates Through Early 2026

One-year total return: approximately 22 to 26 percent in USD terms. The fund lagged SPUS slightly during the 2025 US tech rally because of its international diversification.

Three-year annualized: approximately 13 to 15 percent in USD.

Five-year annualized: approximately 11 to 13 percent in USD. The gap versus US-only halal funds has been real because the US has outperformed global developed markets over this period.

Ten-year annualized (where the data exists): approximately 10 to 12 percent in USD.

When you look at ISDW in local currency (GBP or EUR), the picture is different depending on exchange rate movements. Over the past decade, a weak euro has generally helped euro-denominated returns.

Distribution Type

ISDW has two share classes that matter: accumulating (ISDW) and distributing. The accumulating share class reinvests dividends automatically and is the default for tax-efficient holding in many European jurisdictions. The distributing class pays quarterly cash dividends, which some investors prefer.

Distribution yield for the distributing class is approximately 1.0 to 1.4 percent, slightly higher than US halal ETFs because MSCI World's inclusion of international dividend payers brings up the weighted yield.

Comparison to SPUS + UMMA Combo

A common question: should an international investor buy ISDW or should they replicate it with SPUS for US plus UMMA for ex-US?

ISDW pros: single ticker, slightly cheaper fee (0.30 vs blended ~0.50), no rebalancing work, cleaner tax reporting if you're in Europe, MSCI World methodology is well understood and widely tracked.

SPUS + UMMA pros: currency flexibility (you can overweight US if you want), both funds are liquid and well-known, you have the option to rebalance between them at will.

For most non-US investors, ISDW wins on simplicity and cost. For someone who wants active control over US vs international weighting, splitting gives you more flexibility.

Currency Exposure

Because ISDW holds stocks from 20-plus countries, you're exposed to multiple currencies. The fund doesn't hedge currency back to a base currency. When the dollar strengthens, your non-US holdings translate to fewer dollars. When the dollar weakens, the reverse.

Over long time periods, currency effects tend to wash out. Over one-year windows, they can add or subtract 3 to 5 percent from your returns. Most advisors consider this currency diversification a benefit, not a bug, because it reduces dollar-specific risk in your portfolio.

Who ISDW Makes Sense For

European investors who want a single-ticker halal equity solution and don't want to build a multi-fund portfolio. Gulf-based investors looking for a liquid, well-regulated UCITS product to hold in their offshore accounts. Wealth managers who want to give Muslim clients global equity exposure without the headache of running multiple sleeves.

Who Should Look Elsewhere

US investors (who can't buy it anyway). Anyone who wants US-only exposure (ISDW is about 60 percent US, so you get less concentration than SPUS but also less pure US beta). Investors who want emerging markets exposure (ISDW is developed markets only).

For EM exposure, iShares also runs the MSCI Emerging Markets Islamic UCITS ETF (ISEM) which you can pair with ISDW for a complete global halal allocation.

Bottom Line

ISDW is quietly the best-engineered halal equity ETF available anywhere. Low fees, broad diversification, respected index provider, iShares operational backing, daily transparency, and decent liquidity. The main reason it's not more famous is that US investors literally cannot buy it, and American investment content dominates the halal finance conversation.

If you're lucky enough to live somewhere that lets you buy UCITS ETFs, ISDW deserves serious consideration as the core of your faith-based portfolio. Pair it with ISEM for emerging markets and a sukuk fund for fixed income, and you've got a complete halal allocation that took you about ten minutes to build.
