US vs Global:
Where should European investors start?
If you’re starting from zero, you don’t need a perfect answer. You need a simple stock exposure you can hold for years — without switching every time headlines change. Here’s how to think about it as a European investor.

TL;DR
- Simple — one decision, one ETF.
- Concentrated in a single country and currency (USD).
- Strong long-run track record, no guarantee it continues.
- Works well if you stay consistent and don’t performance-chase.
- Still heavily US (typically 60–70%) — not a rejection of the US.
- Spreads exposure across other developed (and EM) markets.
- Reduces single-country concentration risk.
- One ETF option available — no rebalancing needed.
What “US vs global” actually means
When you buy a stock ETF, you’re choosing which companies to own. “US” and “global” are just labels for which markets are included.
| Approach | What you own | UCITS example |
|---|---|---|
| US-only | Companies listed in the United States | iShares Core S&P 500 (CSPX) |
| Developed world | US + Europe + Japan + other developed markets | iShares MSCI World (IWDA) |
| All-world | Developed + emerging markets in one fund | Vanguard FTSE All-World (VWCE) |
| Global ex-US | Everything except the United States | Used to complement a US ETF |
MSCI World is roughly 70% US stocks. FTSE All-World is around 60% US. Choosing “global” is not a bet against America — it’s a bet on a slightly more diversified set of companies that still has the US as its largest component.
The difference between US-only and global is how much weight you give to non-US developed markets (Europe, Japan, Canada, etc.) and, with FTSE All-World, emerging markets.
Four factors that change the calculation for EU investors
The US vs global debate looks different from a European perspective. These factors don’t change the answer — but they change what you should be thinking about.
Most EU retail investors cannot buy US-domiciled ETFs (SPY, VOO, QQQ) due to PRIIPs/KID regulations. You use UCITS equivalents instead: same index, EU-compliant wrapper, usually domiciled in Ireland. The cost difference is small; the regulatory barrier is real.
When you buy a USD-denominated ETF from a EUR-denominated account, your broker converts currencies — at a cost. On a US-only ETF held long-term this is manageable. On repeated monthly contributions it compounds. IBKR minimises this; some neobrokers charge 0.15–0.5% per conversion.
A US-only portfolio concentrates your returns in USD. If the dollar weakens against the euro, your EUR-denominated returns fall even if US stocks rise. A global ETF spreads exposure across USD, JPY, GBP, and other currencies — which may or may not help depending on the period.
Ireland-domiciled UCITS ETFs benefit from a 15% US dividend withholding rate (vs 30% for non-treaty domiciles). If you hold a distributing ETF, dividends flow through. If you hold accumulating, they’re reinvested with lower friction. Confirm your country’s rules — Germany, Italy, Spain, and the Netherlands all handle this differently.
Three approaches that work for most European investors
You don’t need niche country funds or complex tilts. Pick one of these and execute it consistently.
One ETF tracking the 500 largest US companies. Easy to understand, low cost, liquid. You accept US-only concentration in exchange for simplicity.
Trade-off: 100% USD exposure, single-country risk, no ex-US diversification.
One ETF covering developed markets (MSCI World) or developed + emerging (FTSE All-World). Still heavily US, but with automatic global diversification baked in. No rebalancing needed.
Trade-off: Slightly lower US concentration, a little more complexity to understand what you own.
Two ETFs: one US, one rest-of-world. Lets you set your own US weight (e.g. 70/30). Requires occasional rebalancing. More decisions, more control.
Trade-off: More maintenance, more decisions — and more chances for behaviour errors.
Which approach suits you
| Your situation | Lean toward |
|---|---|
| First time investing, want maximum simplicity | S&P 500 UCITS or FTSE All-World UCITS |
| Want diversification and zero rebalancing effort | FTSE All-World UCITS (single fund) |
| Want to set a specific US tilt and don’t mind two funds | S&P 500 + Global ex-US (e.g. 70/30) |
| Income/job already tied to the US economy | Global mix (reduce concentration) |
| Spending entirely in EUR, long horizon | Either works — FX impact is long-run noise |
| Prone to switching when one region underperforms | One all-world fund — remove the temptation |
Starting with a global ETF, watching US stocks outperform for a year, switching to US-only — then watching Europe or EM recover and switching back. This is performance-chasing. It destroys returns.
The correct play: pick an allocation that reflects your convictions (if any), set it up, automate contributions, and leave it alone for years at a time.
Common mistakes
Switching between US-only and global every 12–18 months based on which did better recently. Both approaches are long-run strategies — treat them that way.
MSCI World is ~70% US. FTSE All-World is ~60% US. Adding a global fund alongside a US fund creates massive overlap. Check the combined exposure before assuming you’re diversified.
ETF choice matters less than what your broker charges to convert EUR to USD on every contribution. Use a broker with low FX fees (IBKR is best in class; many neobrokers charge 0.15–0.5%).
An imperfect decision made now beats a perfect decision made in two years. Pick the simplest option (one ETF), set up a monthly contribution, refine later.

Pick one ETF (S&P 500 or FTSE All-World), automate monthly contributions, and stop tinkering. That’s the whole strategy.

Frequently asked questions
What is the difference between a US ETF and a global ETF?
A US ETF holds only companies listed in the United States. A global ETF holds companies from many countries, weighted by market size — and typically still includes a large US allocation (often 60–70%). US-only concentrates risk in one country; global spreads it across regions while keeping significant US exposure.
If a global ETF already contains the US, why not just buy a global ETF?
That is a perfectly valid approach and the one many investors choose for simplicity. An all-world or MSCI World ETF gives you US exposure plus diversification into other developed markets without any extra decisions. The main trade-off is slightly lower US concentration — which many investors consider a feature, not a bug.
Does currency risk matter when choosing between US and global ETFs?
Yes, especially for EU investors. A US-only ETF concentrates your currency exposure in USD. A global fund spreads it across multiple currencies. Neither is inherently better — but if your income and expenses are in EUR, a global mix reduces the impact of a single currency swing on your portfolio. Over very long horizons, currency effects tend to wash out, but they can be significant in shorter windows.
Can EU investors buy US-domiciled ETFs like SPY or VOO?
Most EU retail investors cannot, due to PRIIPs/KID regulations that require a standardised KID document for retail products — which US ETFs don’t provide. The practical solution is UCITS-compliant equivalents: funds that track the same indices (S&P 500, MSCI World, FTSE All-World) but are domiciled in Ireland or Luxembourg and are fully accessible to EU investors.
Which is better long term — US-only or global?
No one can reliably predict which will outperform over the next 20 years. US stocks led for a long stretch; other regions have led before and will likely lead again at some point. Regional leadership rotates over decades. The more important decision is picking an allocation you can hold through full market cycles without switching based on recent performance — that consistency matters more than which specific index you chose.
