How to choose a world ETF:
MSCI World vs FTSE All-World
A world ETF is the backbone of most long-term portfolios. The choice isn’t about finding the “best” fund — it’s about getting coverage, costs, and execution right once, then leaving it alone. This guide gives you a checklist that works for years.

TL;DR
- MSCI World = Developed Markets only. “Global-ish”, not truly global.
- FTSE All-World = Developed + Emerging Markets. Closer to “own the world” in one fund.
- Most people should optimise: (1) coverage, (2) real costs, (3) execution, (4) behaviour.
- Ignore: fund trading currency, TER in isolation, annual “best ETF” lists.
- Want one fund that includes Emerging Markets? → FTSE All-World.
- Happy with Developed Markets only? → MSCI World is fine.
- Don’t want to decide at all? Pick a broad UCITS ACWI-style fund, set up recurring buys, and stop.
MSCI World vs FTSE All-World: the only difference that matters
Both are valid choices. The distinction is not quality — it’s scope. Everything else is a secondary decision.
- ~1,400–1,500 large and mid-cap stocks.
- 23 developed countries: US, EU, Japan, UK, etc.
- Excludes Emerging Markets entirely.
- Common “simple global” default in Europe.
Pick if: you want Developed-only exposure, plan to add EM separately, or consciously skip it.
- ~4,000+ stocks across 50+ countries.
- Developed Markets (~90%) + Emerging (~10%).
- One fund does the EM allocation automatically.
- Fewer moving parts, fewer rebalancing decisions.
Pick if: you want one-fund global coverage without managing a second EM allocation.
World ETF checklist: pick in 10 minutes
Four decisions in the right order. Don’t jump to step 3 before you’ve settled step 1.
- MSCI World = Developed only.
- FTSE All-World = Developed + Emerging.
- Single question: do you want EM included automatically?
- EU retail: use UCITS (not US-domiciled ETFs).
- Accumulating vs distributing — match your tax rules.
- Physical replication preferred for broad equity; synthetic is not automatically worse.
- TER is one component — tracking difference is the full picture.
- Buy the most liquid listing you can access.
- Avoid repeated FX conversion if your broker charges for it.
- Use limit orders if spreads are wide.
- Avoid the first and last 15 minutes of the session.
- Pick one fund and keep buying — behaviour beats optimisation.
TER is not your total cost
Most investors compare TERs and stop there. That misses the components that actually drive long-run drag.
| Cost component | What it is | Typical impact |
|---|---|---|
| TER | Stated annual management charge | Visible — but not the whole picture |
| Tracking difference | Fund return vs index return (can be negative — a gain) | The real cost measure to compare |
| Bid-ask spread | Cost paid at execution on each trade | Matters most for regular investors |
| FX conversion | Currency exchange when buying non-EUR ETFs | Real drag if done repeatedly |
| Trading behaviour | Switching funds, market timing, overreacting | Biggest long-run drag for most investors |
A fund with TER 0.20% but poor tracking and wide spreads can cost more than one at 0.22% with tight spreads and strong tracking. Compare tracking difference, not just the headline fee.
Four traps that leak long-term returns
A EUR-traded world ETF does not remove currency risk. Exposure comes from the underlying companies and their revenues. If the fund holds Apple, Microsoft, and ASML, you have USD and EUR revenue exposure — regardless of what currency the ETF trades in.
TER is not total cost. Tracking difference and bid-ask spreads frequently dominate. A 0.02% TER difference matters far less than whether you trade during illiquid hours or convert currency on every contribution.
Switching to the “best” fund each year creates realisation events, spreads costs, and behavioural drag. A robust fund held consistently beats a fragile “perfect” fund you’ll second-guess every 12 months.
Most EU retail investors cannot buy US-domiciled ETFs (VWRA, VTI, etc.) through standard brokers due to PRIIPs/KID rules. Don’t plan around US tickers — use UCITS equivalents. Same index, compliant wrapper.
How to buy without giving back returns on execution
- Automate monthly contributions — calendar beats motivation.
- Use limit orders when spreads widen (volatile days, open/close).
- Buy the most liquid listing on your broker (highest AUM, tightest spread).
- Keep it to 1–2 funds. Adding funds adds rebalancing decisions forever.
- Market orders during the first/last 15 minutes of the session.
- Converting currency on every monthly buy (FX drag compounds).
- Holding 8+ funds because each “fills a gap” — complexity is a cost.
- Pausing contributions when the market is down — that’s when you’re buying cheaper.

Frequently asked questions
Is MSCI World enough as a one-fund portfolio?
It can be, but it excludes Emerging Markets. The real question is whether you want that exclusion by design — or whether you’d rather use FTSE All-World and have EM included automatically. Neither is wrong; the distinction is intentionality.
What is the actual difference between MSCI World and FTSE All-World?
Coverage. MSCI World tracks Developed Markets only (~1,400 stocks). FTSE All-World adds Emerging Markets in the same fund (~4,000+ stocks). Everything else — costs, replication method, share class — is a separate decision you make independently of the index choice.
Does an ETF trading in EUR remove currency risk?
No. Currency risk comes from the underlying companies and their revenues, not the trading currency of the ETF. A EUR-denominated world ETF still has full USD, JPY, and GBP exposure through its holdings. The trading currency mainly affects the FX step when you buy or sell.
Is the lowest TER always the best world ETF?
No. TER is not your total cost. Tracking difference, bid-ask spreads, FX conversion, and your own trading behaviour often matter more than a 0.02–0.05% difference in stated fees. A fund with a slightly higher TER but tighter spreads and better tracking can be cheaper in practice over a long holding period.
Can EU retail investors buy US-domiciled world ETFs?
Usually not through standard retail brokers. PRIIPs/KID regulations restrict most EU retail investors from buying US-domiciled ETFs (like VTI, VWRA, or SPY). UCITS equivalents — same index, EU-compliant wrapper — are the standard route. Confirm what your specific account can access before planning around US tickers.
