VWCE holds the FTSE All-World — 3,745 stocks across developed and emerging markets. IWDA holds MSCI World — about 1,400 names across developed markets only, no EM. The fee gap is one basis point, the wrapper is identical, and the entire decision collapses to a single question: do you want the emerging-market sleeve, or not?
What they share
Both are Irish-domiciled UCITS ETFs. Both accumulate dividends inside the wrapper — no quarterly cash to redeploy, no tax event until you sell. Both do physical replication with optimized sampling: they hold a representative subset of the index, not every name, which is standard for indices this broad. The Ireland/US tax treaty applies in both cases, which is the load-bearing detail for a Euro investor — withholding on the US portion of the dividends is meaningfully lower than holding a US-domiciled equivalent. From a wrapper and tax standpoint, the two funds are interchangeable.
The list-price difference between providers (Vanguard for VWCE, iShares for IWDA) doesn't matter at the broker level — both list across the major European venues, both clear on Trade Republic and Scalable savings plans, both are liquid enough that bid-ask is a non-issue at retail size.
Where they differ
On fees, VWCE charges 0.19% and IWDA charges 0.20%. At a €50k portfolio that's €95 vs €100 per year, a five-euro gap. Forget it — at this resolution the two funds are tied on cost and the decision lives elsewhere.
The real difference is what's in the index. MSCI World covers 23 developed markets — US, Western Europe, Japan, Australia, Canada, a few others — about 1,400 large- and mid-cap stocks representing roughly 85% of each market's free float. FTSE All-World covers 49 countries, adding the emerging-market complex (China, India, Taiwan, Korea, Brazil, South Africa, and ~20 others) on top of the developed-world set. That's the entire disagreement: ~10% of global market cap lives in the EM sleeve, and IWDA deliberately leaves it out.
AUM scales accordingly. IWDA is the single largest UCITS ETF in Europe at ~€110 billion — it's been the default developed-markets workhorse for a decade. VWCE is smaller but newer (launched 2019) and is the most-popular savings-plan choice on Trade Republic and Scalable specifically because it ships the EM sleeve in one trade.
Holdings overlap is closer than you'd expect, but the weights tell the story:
| Ticker | Name | Weight |
|---|---|---|
| NVDA | NVIDIA Corp | 5.30% |
| AAPL | Apple Inc | 4.67% |
| MSFT | Microsoft Corp | 3.27% |
| AMZN | Amazon.com Inc | 2.51% |
| GOOGL | Alphabet Inc Class A | 2.09% |
| Ticker | Name | Weight |
|---|---|---|
| NVDA | NVIDIA Corp | 4.44% |
| AAPL | Apple Inc | 3.98% |
| MSFT | Microsoft Corp | 2.99% |
| AMZN | Amazon.com Inc | 2.17% |
| GOOGL | Alphabet Inc Class A | 1.82% |
The top names are nearly identical — Apple, Microsoft, NVIDIA, Amazon, Alphabet, Meta — because US mega-caps dominate any global cap-weighted index. But IWDA's top five clear 17.6% of the basket while VWCE's top five sit at 15.4%. Same companies, less concentrated in VWCE, because VWCE has ~2,300 additional EM and small/mid DM stocks pulling each top weight down. Concentration goes the same direction across the full top ten (IWDA 24.4% vs VWCE 22.4%).
Currency on the share class is cosmetic: IWDA lists on the LSE in USD, VWCE on XETR in EUR. As a Euro investor your real FX exposure tracks the underlying basket regardless of which share-class ticker you hold — both baskets are USD-dominated, with VWCE adding a sliver of EM-currency exposure on top.

Is the EM sleeve worth it?
Honest answer: the historical record favors IWDA — emerging markets have underperformed developed for the better part of fifteen years, and a DM-only portfolio has compounded faster as a result. That's the bear case against VWCE in one line.
The forward case is the opposite. EM is ~10% of global market cap; holding the global market cap weighting is the agnostic position, and any deliberate exclusion (DM-only, US-only, small-cap-only) is an active bet that something specific about the excluded slice will continue underperforming. IWDA's outperformance over the past decade is already priced in — that's how markets work.
If you want a separate EM weighting decision, the third option is "IWDA core + EIMI on top" — iShares' EM IMI ETF — which lets you size the EM sleeve yourself rather than accepting the FTSE All-World default. That's a sensible move for someone who specifically wants to overweight or underweight EM relative to global market cap. It's overhead for someone who doesn't have a view.
Who each one is for
Buy VWCE if you want one fund and you're done. It's the cleaner default for someone who doesn't have a view on EM, doesn't want to make a view, and wants the global market cap basket without splitting trades. Most Euro investors building a passive long-term portfolio land here — including the savings-plan crowd on Trade Republic and Scalable, which is exactly why VWCE has overtaken IWDA as the default recommendation in the past few years.
Buy IWDA if you specifically want DM-only exposure — either because you have governance/volatility reservations about EM, or because you plan to control the EM weight separately with EIMI as a satellite, or because you're already running a US-tilted core like VUAA and want a non-US DM complement that doesn't double-count emerging exposure. IWDA's €110B AUM and decade-long track record speak for themselves; it's not a worse fund, just a narrower one.
For a different cut of the same question, see VUAA vs VWCE — that one's about US-only vs all-world, which is the more aggressive concentration trade. This one's about whether EM is worth a sleeve at all. Both decisions are real; neither has a wrong answer if you know which question you're answering.
