The complete ticker breakdown is in IWDA in detail.

— we cross-checked figures against MSCI methodology PDFs. Additionally, we consulted iShares and Xtrackers KIDs, UBS and Amundi factsheets, plus justETF screener data. Every fund figure on this page was re-read from justETF on 26 August 2026.

The short answer: IWDA/SWDA/EUNL (IE00B4L5Y983) is the same fund and costs 0.20% with EUR 126.7bn behind it; XDWD (IE00BJ0KDQ92) costs 0.12% with EUR 20.6bn; UBS Core MSCI World (IE00BD4TXV59) is the cheapest full-replication option at 0.06% with EUR 10.5bn. If you are starting fresh and your broker lists it, take the 0.06% fund. If you already hold EUNL in a savings plan, the 14-basis-point gap is not worth a migration. All figures justETF, 26 August 2026.

European investors seek global diversification through MSCI World ETFs. Crucially, they access some of the world’s most liquid and cost-effective investment vehicles. Combined AUM in the four Irish-domiciled lines compared on this page is about EUR 188 billion. For eleven years I have run my own MSCI World core position across IBKR, Trade Republic and DEGIRO. Therefore, I have spent enough time in justETF, KID PDFs and broker savings-plan menus to know one thing. Picking between IWDA, SWDA, EUNL, XDWD and the cheaper newcomers is rarely about TER alone. In practice, it comes down to ticker availability on your broker, currency of the listing, and replication method. Moreover, you must decide whether you actually want emerging markets sneaking back in via ACWI.

The ETF expense-ratio math shows the 30-year cost of a 0.10% TER difference on €1,000/month.

This article sits inside our VWCE vs all-world ETF comparison hub. Additionally, it pairs with our European ETF investing beginner roadmap for readers still deciding between a single-ticker all-world solution and a MSCI World plus EM split.

Best MSCI World ETFs for European Investors

Understanding the MSCI World Index

The MSCI World Index tracks large- and mid-cap stocks from 23 developed countries. Notably, it covers roughly 85% of free-float market capitalisation in each market. As of the latest factsheet, US weight sits at 71.86%, Japan 5.43%, and UK 3.65%. France, Canada, Switzerland and Germany round out the top seven. MSCI publishes the full constituent list at MSCI. Additionally, you can track it in a searchable form on justETF.

Selection criteria: the ETF selection methodology explains exactly how funds earn a place in this comparison.

What the index does not include matters as much as what it does. Notably, it excludes emerging markets, so you get no Taiwan, India, or China A-shares. Furthermore, it skips the small-cap segment, which the MSCI World Small Cap and IMI variants cover. It also excludes frontier markets. For a European investor that means one thing. A single MSCI World ETF leaves roughly 10-12% of global equity market cap on the table, mostly EM. The most common fixes are ACWI, IMI or a MSCI World plus EM combo. However, each has trade-offs in TER, sampling accuracy, and rebalancing friction. I unpack these later in this guide.

MSCI reviews methodology quarterly with a semi-annual index review. Additionally, they publish additions and deletions in advance on the MSCI site. This matters because tracking difference vs the index is the real cost number that beats raw TER. For example, a 0.20% TER fund with -0.05% tracking difference is cheaper than a 0.12% TER fund tracking at -0.18%.

Top MSCI World ETFs for 2026

iShares Core MSCI World UCITS ETF dominates the segment with EUR 126,744m — not the EUR 96.8bn an earlier version of this page carried, which was roughly a quarter out of date (justETF, 26 August 2026). See the iShares product page for details. That AUM stems from a decade as the default pick on Trade Republic savings plans, IBKR and most German and Dutch brokers. Its 0.20% TER looks expensive next to newer entrants. However, the sheer depth of liquidity on Xetra, LSE and Borsa Italiana means spreads typically run 0.02-0.05% during European hours. Notably, this delivers a real-money saving that beginners underestimate.

Below iShares, the price war has compressed TERs aggressively. UBS Core MSCI World comes in at 0.06% TER. This makes it the cheapest physical full-replication UCITS option I track. Amundi Prime Global / MSCI World holds 0.05-0.12% depending on the share class. Additionally, Xtrackers XDWD sits at 0.12% with optimised sampling. SPDR, Invesco and HSBC complete the field. However, they sit at sub-EUR 5B AUM each, so liquidity on smaller venues is the trade-off.

For my own portfolio I still hold EUNL despite the 0.20% TER. Here is why: Trade Republic offers it free in savings plans. Additionally, tracking difference has historically run -0.06 to -0.10%, which means the real cost of holding it has been 0.06 to 0.10% a year, not the 0.20% headline TER — securities-lending revenue and withholding-tax optimisation close most of the gap. An earlier version of this page said ‘below 0.30%’, which had the arithmetic pointing the wrong way. Furthermore, I do not want to migrate a six-figure position for 8 basis points. For a new investor starting fresh in 2026 with no legacy holding, UBS or Amundi at 0.05-0.06% is the rational pick. However, this only works if your broker lists them.

Tax Efficiency: Why Irish Domicile Wins for Europeans

Irish-domiciled UCITS ETFs reduce US dividend withholding tax from the headline 30% to 15%. Notably, this comes thanks to the Ireland-US tax treaty. Consider a MSCI World portfolio with ~1.7% gross dividend yield and ~71% US weight. That 15 percentage-point WHT saving works out to roughly 18 basis points of annual return preserved. Crucially, this comfortably beats the difference between the cheapest and most expensive TERs in the table below.

Luxembourg-domiciled ETFs only get a 15% treaty rate too in most cases. A few Amundi and Lyxor legacy lines still use this domicile. However, Ireland has historically had cleaner ETF-level reporting and broader broker support across the EU. UCITS itself sits under the EU-wide framework codified by ESMA. National regulators enforce it, including BaFin in Germany and CySEC in Cyprus. Our UCITS ETF complete guide covers the full UCITS framework, including diversification limits and leverage rules.

One more tax angle deserves a flag. Accumulating Irish UCITS are typically more tax-efficient in jurisdictions that only tax realised gains. For example, Germany applies partial Teilfreistellung, Belgium has no annual tax, and Czech Republic uses a 3-year holding rule. However, in countries with annual deemed-distribution taxes, the picture changes. By contrast, in the Netherlands Box 3 or Denmark “lagerprincippet”, the accumulating vs distributing distinction matters far less for headline tax and more for cash-flow timing.

Detailed ETF Analysis

iShares Core MSCI World UCITS ETF (IE00B4L5Y983) — 0.20% TER, 1,326 holdings, physical full replication, accumulating. This is the default. It lists as IWDA on LSE in USD, SWDA on LSE in GBP, and EUNL on Xetra in EUR. Additionally, you find it on Borsa Italiana and SIX. Tracking difference has run consistently in the -0.05% to -0.10% band over rolling three-year windows per justETF data.

Xtrackers MSCI World UCITS ETF 1C (IE00BJ0KDQ92) — 0.12% TER, optimised sampling, accumulating, EUR 20,584m and running since 22 July 2014 (justETF, 26 August 2026). It lists as XDWD on Xetra. See the Xtrackers XDWD KID for replication detail. This is a solid second pick for German-broker users.

UBS ETF MSCI World UCITS ETF (IE00BD4TXV59) — 0.06% TER, physical full replication, accumulating. This is the cheapest physical full-replication MSCI World UCITS at the time of writing. It holds EUR 10,523m and launched on 7 June 2019 (justETF, 26 August 2026) — an eighth of the iShares fund, but comfortably large enough that closure is not a concern. Still worth checking spreads on your venue during volatile sessions.

Amundi Prime Global UCITS ETF — tracks Solactive GBS Developed Markets Large & Mid Cap (a close MSCI World proxy), 0.05% TER, accumulating. Notably, this is not strictly MSCI-licensed. However, the index overlap with MSCI World runs ~98%. Consequently, it is the cheapest “MSCI World equivalent” UCITS for cost-obsessed investors comfortable with a different index provider.

Side-by-side: IWDA vs SWDA vs EUNL vs XDWD vs IUSQ

Three of these tickers (IWDA, SWDA, EUNL) are the same underlying iShares fund. They share IE00B4L5Y983 and just have different listings. XDWD is the Xtrackers MSCI World 1C. IUSQ is the iShares Core MSCI ACWI UCITS ETF. We include it here because it is the most commonly considered MSCI World alternative that does include emerging markets.

Two practical takeaways emerge from the table. First, EUNL and XDWD are the only two of the five that get full coverage on the German neobroker free-savings-plan menus. This matters if you DCA EUR 100-500 per month. Second, IUSQ swaps developed-market purity for ~10% EM weighting at the same 0.20% TER as IWDA. Therefore, it offers the simplest “one-ticker global” solution if you want EM included without running a separate emerging-markets ETF. See our EUNL vs IUSQ analysis and ISAC vs IWDA comparison for the deeper fee math.

European broker availability and savings plans

Trade Republic, Scalable Capital, ING DiBa and Comdirect all offer EUNL and XDWD in free or near-free savings plans. Minimums run at EUR 1-25 per month. Consequently, they are the practical default for German, Austrian and Dutch DCA investors. Interactive Brokers lists all five tickers above. Notably, it is the venue of choice for anyone wanting a single global account with multi-currency support. DEGIRO carries IWDA and EUNL in its core selection, commission-free under monthly limits. Meanwhile, XTB and Freedom24 cover the major Xetra and LSE listings. The full broker breakdown sits in our best European ETF brokers hub and best global ETFs guide.

MSCI World vs FTSE Developed vs the EM gap

The MSCI World vs FTSE Developed debate is mostly noise. Both indices exclude EM. Additionally, both have ~71% US weight. Historical tracking differences between IWDA and a FTSE Developed UCITS (e.g. VEVE) sit within 10-20 basis points per year. The bigger question is whether to fill the EM gap. Consider three approaches:

Approach 1: MSCI World only. You accept ~10-12% missing EM exposure. This route is cheapest and simplest. It works fine if you believe developed markets will continue to dominate global earnings growth.

Approach 2: MSCI ACWI (IUSQ) or FTSE All-World (VWCE). You use a single ticker, with EM included at ~10% weight. ACWI uses MSCI. By contrast, All-World uses FTSE, which classifies Poland and South Korea differently. They run 0.14-0.20% TER.

Approach 3: MSCI World plus EM split, e.g. EUNL 88% plus EIMI 12%. This lets you control the EM weight. Some investors want 15-20% rather than the index 10%. Additionally, it lets you choose cheaper underlying tickers. However, the trade-off is manual rebalancing, two transactions per DCA, and the discipline to actually do it.

I run Approach 3 for my own core position. My EM weight sits slightly overweight at 14%. Notably, EM is where future growth surprises concentrate per long-run Dimson-Marsh-Staunton data. New investors with portfolios under EUR 50k should default to Approach 2 (single ticker). Therefore, they avoid the operational complexity. See VWCE vs alternatives and best ex-US ETFs for the longer comparison.

Frequently asked questions

EUNL vs IWDA — which should I buy?

Neither, in the sense that matters: they are the same fund. IE00B4L5Y983, one portfolio, one TER of 0.20%, one set of holdings. EUNL is the euro line on Xetra and IWDA is the dollar line on the London Stock Exchange. For a euro-based investor the answer is almost always EUNL, for one reason: buying the dollar line means your broker converts euros to dollars on every purchase and back on every sale, typically at 0.15% to 0.5%, which dwarfs anything else in this comparison. Buying EUNL does not remove your dollar exposure — 71% of the fund is American either way — it removes the broker’s conversion fee. The exception is if you already hold and earn dollars, in which case IWDA avoids the conversion instead.

EUNL vs VWCE — what is the actual difference?

Emerging markets, and about six basis points. EUNL tracks MSCI World: 23 developed countries, no EM, 0.20%. VWCE tracks FTSE All-World: developed plus roughly 10% emerging markets, 0.14%. So VWCE is both broader and cheaper, which is why it is the more common single-ticker default. The counter-arguments for EUNL are that it is available free in more German savings plans, that its tracking difference has been excellent, and that some investors deliberately want to control their EM weight separately rather than accept the index’s 10%. Do not hold both as your core: you would own developed markets twice and call it diversification.

Which broker is best for an MSCI World ETF?

For a euro investor running a monthly savings plan: Trade Republic, Scalable Capital, ING DiBa or Comdirect, all of which carry EUNL and XDWD in free or near-free plans from EUR 1 to EUR 25 a month. For a lump sum or a multi-currency portfolio: Interactive Brokers, which lists every ticker on this page. For a low-cost middle ground: DEGIRO, if your fund sits on its Core Selection, or Trading 212 if you buy the euro-quoted line. The broker choice matters more than the fund choice at small contributions — a EUR 1 fee on a EUR 100 monthly buy is 1%, five times the most expensive TER here.

Difference between IWDA and SWDA?

Same fund, IE00B4L5Y983. IWDA is the USD line on LSE. SWDA is the GBP line on LSE. By contrast, EUNL is the EUR line on Xetra. All three share the underlying portfolio. Your broker’s venue access and the currency you want to settle in determine which ticker you buy.

Does MSCI World include EM?

No. MSCI World covers developed markets only. For emerging-markets exposure use MSCI ACWI (IUSQ) as a single-ticker solution. Alternatively, FTSE All-World (VWCE) offers a close FTSE-classified alternative. You can also pair MSCI World with a dedicated EM ETF like EIMI.

Accumulating or distributing?

It depends on tax residency and cash-flow needs. Accumulating share classes (IWDA, EUNL, XDWD) compound dividends inside the fund. Therefore, they are typically better in jurisdictions that only tax realised gains. By contrast, distributing classes (SWRD, VHVE) pay quarterly. They suit investors needing income or operating in tax regimes with explicit dividend allowances.

Why Irish-domiciled UCITS?

Three reasons stand out. First, 15% US dividend WHT applies via the Ireland-US treaty, vs the 30% headline. Second, no US estate-tax exposure hits non-resident holders. Third, ESMA-supervised UCITS rules work across all EU member states without per-country distribution headaches.

Cheapest MSCI World ETF 2026?

UBS Core MSCI World at 0.06% TER is the cheapest physical full-replication MSCI-licensed option. Amundi Prime Global at 0.05% TER is technically cheaper. However, it tracks the Solactive GBS Developed proxy index. Xtrackers XDWD sits at 0.12% with optimised sampling. iShares IWDA/SWDA/EUNL remains 0.20% but offers the deepest liquidity.

MSCI World vs S&P 500?

MSCI World adds 22 other developed markets to US large/mid-caps. However, ~71% US weight means high overlap with the S&P 500. The diversification benefit is real but modest. In practice, you are mostly adding Japan, UK, France and Switzerland. For a meaningfully different return profile you need EM exposure (ACWI/All-World) or a factor tilt.

Savings plan availability?

Yes. Trade Republic, Scalable Capital, ING DiBa, Comdirect and DEGIRO all offer EUR 1-25 per month savings plans on EUNL and XDWD. Typically these run commission-free. Consequently, they are the practical default for DCA investors building a position over 5-10 years.
