International ETFs: VXUS, IXUS, VEA, VWO - Do You Need Them?

International exchange-traded funds (ETFs) offer a way to diversify a portfolio beyond U.S. stocks by gaining exposure to foreign companies in both developed and emerging economies. The choice between them hinges on how much international exposure you want, which markets you're targeting, and whether you prioritize low cost or higher growth potential. Rather than pick individual funds, you'll want to think through your asset allocation philosophy first, then choose the vehicles that match it most cheaply.

What an International ETF Is, and the Main Types

An international ETF pools money to buy stocks issued by companies outside the United States. Vanguard suggests that international investments make up about 40% of the stock portion and 30% of the bond portion of a diversified portfolio. That's the starting point for thinking about whether you need these funds at all, and if so, how much to own.

The search results show you have three broad categories to consider:

1. Total international funds combine developed and emerging markets in one holding. The Vanguard Total International Stock ETF (VXUS) tracks the FTSE Global All Cap ex US Index, which covers 98% of the world's non-U.S. markets, including Europe, the Pacific region, and emerging economies. This is the "one-fund" simplicity approach.

2. Developed markets ETFs focus on established economies like Japan, the United Kingdom, Canada, and France. The Vanguard FTSE Developed Markets ETF (VEA) invests in established markets across Canada, Europe, and the Pacific region.

3. Emerging markets ETFs target faster-growing but riskier economies. The iShares Core MSCI Emerging Markets ETF (IEMG) focuses on developing economies, which offer higher growth potential alongside higher geopolitical and currency risks.

Developed Markets Versus Emerging Markets: The Core Tradeoff

The fundamental question is whether you want steadier returns from wealthy, stable countries or higher upside potential (with higher volatility) from emerging economies.

As of October 1, 2026, VEA returned 19.4% over the prior year, while the iShares EAFE fund (IEFA), which also tracks developed markets but excludes Canada and South Korea, returned 13.1%. The gap exists partly because different index providers classify South Korea differently. Over five years, VEA delivered a total return of 57% (a compound annual growth rate of 9.5%), while IEMG delivered 45% for a CAGR of 7.7%. Developed markets have outperformed recently, but that outcome is not guaranteed in future years.

Here is how the major funds compare on expense ratio, recent returns, and yield:

The Cost and Geographic Allocation Question

VEA has a 0.03% expense ratio, the lowest in this group, and offers a higher dividend yield of 2.4%, while IEMG's is 0.09% and yields 2.2%. For a $10,000 investment, that means you'd pay about $3 per year in fees with VEA versus $9 with IEMG, a modest but real difference over decades.

Geographic concentration is another consideration. VEA is more geographically diverse, with its largest country allocations being Japan (21%), Canada (11%), and the United Kingdom (10%). In contrast, IEMG tilts heavily toward East Asia, with Taiwan (29%), South Korea (19%), and China (17%) making up roughly two-thirds of the fund. If you believe Asia's growth story, IEMG's concentration is a feature. If you prefer regional balance, VEA is more balanced. And if you want both without managing two positions, VXUS at 0.05% provides a middle ground, blending developed and emerging in one fund.

Do You Need International Exposure at All?

The case for: International stocks provide diversification away from U.S. market movements, offer exposure to faster-growing regions (particularly emerging Asia), and have historically had periods of strong performance. The case against: The U.S. market represents a disproportionately large share of global market cap, U.S. companies are often multinational anyway, and international markets carry currency risk, geopolitical uncertainty, and complexity. Reasonable investors land on both sides.

If you do allocate to international stocks, using MMD as a tool to track and compare the expense ratios, annual returns, and geographic weightings across a few candidate funds helps you make an intentional choice rather than a default one. The funds above are all low-cost, liquid, and suitable for long-term holding, so the real decision is how much international exposure aligns with your worldview of risk, growth, and diversification.

FAQ

What is the difference between VEA and VXUS? VEA focuses on developed markets outside the U.S., while VXUS blends developed and emerging markets. VEA has a lower expense ratio (0.03% vs. 0.05%) but has also delivered higher recent returns. VXUS offers one-stop simplicity.

Should I own both developed and emerging markets ETFs, or just one? If you own VXUS or IXUS, you already own both. If you prefer to split them, you might pair VEA with an emerging markets fund like IEMG to customize your geographic tilt. There's no universal right answer; it depends on your conviction about growth versus stability.

Why does emerging markets performance vary so much year to year? Emerging markets are riskier, more volatile, and more sensitive to currency swings and geopolitical events than developed markets. That volatility can lead to both outsized gains and outsized losses, sometimes years apart.

Which international ETF has the lowest cost? VEA carries a 0.03% expense ratio, the lowest among those listed. VXUS at 0.05% is a close second if you want developed and emerging in one fund.
