Best International ETFs for Global Diversification
Putting everything in US stocks is a home-country bias risk. These are the best international ETFs to add global diversification to your portfolio in 2026.
📚 Part of our Complete Investing Guide
Most American investors put 80-100% of their portfolio in US stocks. That has worked extremely well for the past decade. But history suggests it will not always work — and the investors who ignore the rest of the world are taking a concentration risk they may not realise they have.
International ETFs let you own thousands of companies across dozens of countries in a single fund. Here are the best options in 2026.
Why Invest Internationally?
The US represents about 60% of global stock market capitalisation. That means 40% of investable companies worldwide are outside the US — including some of the world's largest and fastest-growing businesses.
More importantly, different markets do not move in sync. When US stocks struggle, international markets sometimes outperform. From 2000 to 2009, international developed-market stocks significantly outperformed the S&P 500. Adding international exposure smooths out long-term returns.
Best International ETFs in 2026
1. VXUS — Vanguard Total International Stock ETF
Expense ratio: 0.07% | Holdings: ~8,600 stocks | Coverage: Developed + emerging markets ex-US
VXUS is the broadest international ETF available — it holds essentially every publicly traded company outside the US. One fund gives you exposure to Europe, Japan, Canada, emerging markets, and small-cap international stocks all at once. The 0.07% expense ratio is exceptional for this breadth.
This is the default recommendation for anyone who wants complete international exposure with minimal complexity.
2. VEA — Vanguard FTSE Developed Markets ETF
Expense ratio: 0.05% | Holdings: ~4,000 stocks | Coverage: Developed markets only (Europe, Japan, Australia, Canada)
VEA focuses exclusively on developed markets — stable economies with strong institutions, rule of law, and liquid markets. It excludes emerging markets, which some investors prefer for lower volatility.
At 0.05%, it is one of the cheapest international ETFs available.
3. VWO — Vanguard FTSE Emerging Markets ETF
Expense ratio: 0.08% | Holdings: ~5,800 stocks | Coverage: Emerging markets (China, India, Brazil, Taiwan, etc.)
Emerging markets offer higher growth potential — these are economies growing faster than Europe or Japan. But they also carry higher volatility, currency risk, and political risk. VWO is the most cost-effective way to access them.
Most portfolio models suggest keeping emerging markets to 5-15% of total stock holdings.
4. IXUS — iShares Core MSCI Total International Stock ETF
Expense ratio: 0.07% | Holdings: ~4,300 stocks | Coverage: Developed + emerging markets ex-US
IXUS is BlackRock's version of VXUS — similar coverage, same expense ratio. If you use a Fidelity or Schwab account where iShares funds trade commission-free, IXUS is a natural alternative to VXUS.
5. SPDW — SPDR Portfolio Developed World ex-US ETF
Expense ratio: 0.03% | Holdings: ~2,400 stocks | Coverage: Developed markets ex-US
At 0.03%, SPDW ties with VOO for the cheapest broad-market ETF available. The tradeoff is fewer holdings than VEA and no emerging markets exposure. For cost-obsessed investors who want developed-market international exposure only, SPDW is hard to beat.
How Much to Allocate Internationally?
Academic research and most target-date funds suggest somewhere between 20% and 40% international for a globally diversified portfolio.
A simple starting point: if you own a total US market fund (VTI or FXAIX), pair it with VXUS at a 60/40 or 70/30 ratio. This roughly mirrors global market weights while keeping US exposure dominant.
Vanguard's own target-date funds use approximately 40% international. Many investors use less — 20-30% is a reasonable compromise between diversification and familiarity.
The Bottom Line
International ETFs are not exciting. You will not find them in finance headlines. But they do what diversification is supposed to do — reduce the risk that a bad decade in one country derails your entire portfolio.
VXUS for maximum simplicity. VEA + VWO if you want to control developed vs. emerging exposure separately. SPDW if cost is your primary concern and you want developed markets only.
