MSCI World ex USA: Diversification Without the US Overweight
Roughly 70% US in the MSCI World — what worked as a return driver for years has become the biggest single bet in many portfolios. The MSCI World ex USA tracks developed markets without the United States, making it the most precise tool to actively manage your US share instead of leaving it to market capitalization.
The index is not a replacement for the MSCI World but a building block: by adding it, you decide how much US exposure your portfolio carries — relevant amid the valuation debate and de-dollarization discussion.
Index structure: developed markets minus the US
The MSCI World ex USA holds around 800 large- and mid-cap stocks from 22 developed markets. The largest weights: Japan at around 20%, followed by the UK, Canada, France and Switzerland. Sector-wise, financials and industrials dominate — the tech share is markedly lower than in the MSCI World, which makes the index structurally different (not automatically worse).
In Germany the index is investable via ETFs from Xtrackers and Amundi, among others, with TERs of roughly 0.15–0.25%. These products are younger and smaller than the big World ETFs — fund size and spreads are worth a look, though closure risk with established issuers is practically negligible. The usual 30% partial tax exemption for equity funds applies.

Combination strategies: dosing your US share deliberately
The index’s real strength lies in combination. Three typical setups:
- S&P 500 + World ex USA: maximum control, two cheap building blocks, US share freely adjustable.
- MSCI World + World ex USA: dials the US share down from ~70%; a 75/25 mix lands at around 53% US.
- ACWI/All-World + World ex USA: keeps emerging markets, only throttles the US.
A worked example: with €100,000 in an MSCI World ETF, roughly €70,000 sits in US equities. Shifting €25,000 into a World ex USA ETF — or directing future contributions there — cuts the US share to about 53% without losing developed-market diversification. Note the FIFO principle when selling existing holdings: the oldest (usually highest-gain) units count as sold first, triggering German capital gains tax. Redirecting only future contributions is often the smarter tax move.
Historical returns: an honest assessment
The truth first: over the past 15 years the MSCI World ex USA trailed the S&P 500 significantly — US tech was the dominant return driver. Anyone overweighting ex-US in 2010 left returns on the table. But before that there were long stretches with the opposite sign, such as the 2000s after the dot-com bust, when international stocks clearly beat the US. Regional leadership changes are historically the rule, not the exception — only their timing is unpredictable.
The index is therefore not a return promise but a risk tool against portfolio concentration risk. Whether you need it depends on your starting point: a look-through analysis of your portfolio reveals the actual US share across all ETFs and single stocks — it is often higher than expected.

Frequently asked questions
Which countries dominate the MSCI World ex USA?
Japan is the largest weight at around 20%, followed by the UK, Canada, France and Switzerland. The index holds around 800 stocks from 22 developed markets.
Does the MSCI World ex USA replace the MSCI World?
No, it is designed as an addition. Combined with a World or S&P 500 ETF, it lets you dose your portfolio’s US share deliberately instead of leaving it to market capitalization.
Should I shift existing World ETF holdings into ex-USA?
Often unwise for tax reasons: under FIFO, the oldest units with the highest gains are sold and taxed first. Redirecting only future contributions is usually more efficient.
