VWCE or IWDA — Which One Should You Pick?

TL;DR: VWCE and IWDA are the two most popular global ETFs among European investors, and almost every beginner faces this exact choice. The key difference in one sentence: IWDA covers only developed countries (around 1,400 companies, 72% US), VWCE covers developed plus emerging markets (around 3,700 companies, slightly lower US concentration). Below we go through the rest of the differences point by point — and help you figure out which one fits you, with no hidden preferences.

Let's start from the beginning — what are these things?

If you're picking your first global ETF and keep running into these two names, you're not alone. Every second beginner stops at exactly this fork in the road.

IWDA is short for iShares Core MSCI World UCITS ETF. A BlackRock fund that tracks the MSCI World index — large and mid-cap companies across 23 developed countries (US, Europe, Japan, Canada, Australia, etc.). No emerging markets.

VWCE is the Vanguard FTSE All-World UCITS ETF. A Vanguard fund that tracks the FTSE All-World index — covering not just developed but also emerging countries (China, India, Taiwan, Brazil, Mexico, and more).

Both are UCITS funds (more on that in our article on UCITS), both are domiciled in Ireland, and both are accumulating (dividends are reinvested inside the fund rather than paid to your account). And both are excellent choices. The debate isn't "one is good, the other is bad" — it's "which one suits you."

The key difference: with EM or without EM

This is the main point, everything else is secondary. (EM stands for "Emerging Markets" — the developing economies. We'll use this abbreviation throughout, it's standard in investment writing.)

IWDA = developed markets only. About 1,400 companies. US weight around 72%. This is the "safer" choice: an index full of names you know — Apple, Microsoft, Nestlé, Toyota, SAP.

VWCE = developed plus emerging markets. About 3,700 companies. US weight around 62%. The extra ~10% goes to emerging markets. So you get the same set of big global names as IWDA, plus Tencent, Samsung, TSMC, Alibaba, Reliance Industries, and hundreds of others.

To picture it intuitively: buying VWCE means you own a slice of nearly every publicly traded company on the planet. Buying IWDA means you own a slice of every publicly traded company in developed countries.

Annual cost (TER)

There's been an important recent update here. For a long time, IWDA was slightly cheaper than VWCE: 0.20% vs 0.22%. But in October 2025, Vanguard cut VWCE's TER to 0.19%, and now the picture has flipped:

• VWCE — 0.19% per year
• IWDA — 0.20% per year

That's a vanishingly small difference: on a €10,000 portfolio, it's €1 per year. Even over 30 years with a large portfolio the difference isn't decisive — a few thousand euros. Don't make TER the deciding factor between these two funds. Between either of them and some expensive actively managed fund (TER 1.5%+) — yes, that's a massive difference. Between VWCE and IWDA — no.

What about taxes?

Good news — on the fund's side, taxes are identical. Both funds are:

• domiciled in Ireland (domicile = IE at the start of the ISIN)
• accumulating
• equity ETFs (equity share > 51%)

The Irish domicile means that US dividends are taxed at 15% rather than 30% inside the fund (thanks to the Ireland–US tax treaty). This applies to all European investors regardless of their country of residence — and it's one of the main arguments for UCITS funds in general. More on that in our article on UCITS.

Your personal tax, however, depends on your country of tax residence. For example, in Germany both funds fall under the same logic: 30% Teilfreistellung, an effective tax rate around 18.5%, Vorabpauschale, Sparerpauschbetrag — we covered the details in a separate article on German taxes. In Austria, the Netherlands, Italy and other European countries the rules are different — but they all agree on one thing: choosing between VWCE and IWDA has no effect on your taxes, because the funds are structurally identical.

For the specifics in your country, check with a tax adviser.

Historical returns — IWDA slightly ahead (with a caveat)

From VWCE's launch (July 2019) to early 2026 — roughly 6.5 years:

• IWDA grew by about 120% (averaging around 12.4% per year)
• VWCE — about 114% (around 11.9% per year)

A small note for those who want to check the math: "per year" here means the compound annual growth rate (CAGR), not "120% ÷ 6.5 years". This is how it's done because each year's profit gets reinvested and keeps working — so a steady 12% per year produces a very different result than a simple division. CAGR is the standard way to measure long-term returns.

That sounds like "IWDA is better." But it's the wrong conclusion. Here's why.

The period 2019–2026 was a stretch of US dominance. And IWDA is 72% US, while VWCE is 62%. VWCE's lower US weight ate into part of the result — precisely because the US ran ahead of the rest. In a different period (say 2000–2010, or the 1970s, or the 1980s) emerging markets and other developed countries beat the US — and the "winner" would have been different.

Past returns don't predict the future. If you're betting on "the US will keep leading" — go with IWDA. If you think "I don't know who's going to lead the next decade" — VWCE automatically rebalances toward whichever region pulls ahead. That's its whole point.

Volatility — nearly identical

VWCE wobbles slightly more (because of EM, which are more volatile), but the gap is small — about one percentage point. Over a 15–30 year stretch, that's negligible. In short periods (1–2 years) VWCE can dip a bit deeper in bad moments — but it can also bounce back faster.

So which one to pick?

An honest picture for a beginner:

Pick IWDA if:

• You prefer simplicity: "big companies in countries I know"
• You're uncomfortable with the idea of investing in China, India, Russia (for ideological or other reasons)
• You believe the US will keep driving the world economy

Pick VWCE if:

• You want the broadest possible country diversification: "buy the whole world in one fund"
• You acknowledge you don't know which region will lead the next 20 years
• You value automatic rebalancing between regions without your input

What we'd pick (if you ask): for most European beginners, VWCE is the slightly more natural "default" — precisely because it removes the need for you to guess which region will win. It's the "don't think about your portfolio and sleep well" option. But that's not the "correct" answer — IWDA is also an excellent fund, and choosing it isn't a mistake.

A quick 3-point check before you buy

When you find the fund at your broker, before clicking "Buy", check:

1. ISIN — VWCE is IE00BK5BQT80, IWDA is IE00B4L5Y983. If the ISIN is different, it's a different fund (there are many with similar names — don't mix them up).
2. The word "UCITS" in the full name — this means the fund is suitable for European investors and follows EU standards.
3. "Acc" (Accumulating) in the name — if you want the accumulating version. There are also distributing versions of the same funds (with "Dist" in the name) — those pay dividends to your account.

Bottom line

VWCE and IWDA are not "best vs worst" — they're "two very good funds with one important difference": VWCE adds emerging markets on top of developed ones, IWDA stays in developed. Cost is nearly identical (after VWCE's TER cut to 0.19% even slightly cheaper), and structurally both funds are treated the same way for tax purposes — though your actual tax burden depends on your country of residence. Past returns are slightly higher for IWDA thanks to the period of US dominance, but that says nothing about the future. The decision comes down to your view on emerging markets and on the US continuing to lead. Either one is a reasonable choice for a long-term beginner.
