If you're building LatAm ETF exposure, the first real allocation decision is Brazil vs. Mexico. Together, these two markets make up roughly 85% of broad LatAm indexes — and they represent fundamentally different economic bets.
The Core Difference
At the highest level: Brazil is a commodity play and Mexico is a nearshoring play. An oversimplification, but it captures the essential distinction.
EWZ is dominated by companies that extract and process natural resources — Petrobras (oil), Vale (iron ore/metals), and large banks financing commodity-driven growth. EWW is anchored by companies serving consumer and industrial demand — América Móvil (telecom), Walmart de México (retail), Femsa (beverages/convenience).
Head-to-Head
AUM & Liquidity: EWZ is larger at over $11 billion with high volume. EWW is ~$5 billion but still highly liquid. Both trade with tight spreads.
Expense Ratios: Nearly identical — EWZ at 0.59%, EWW at 0.58%. Not a differentiator.
Sector Exposure: This is where divergence matters. EWZ is heavy energy, materials, and financials — cyclical sectors tied to commodity demand. EWW has more consumer staples, telecom, and industrial exposure — sectors benefiting from domestic consumption and trade flows.
The Nearshoring Thesis (Bullish Mexico)
Mexico shares a 2,000-mile border with the world's largest consumer market. USMCA provides preferential access. Labor costs are competitive. Infrastructure is improving. Industrial real estate occupancy in northern Mexico is at historic highs.
This isn't speculative — foreign direct investment into Mexico has been accelerating, and EWW's holdings capture the economic ripple effects through consumer spending, industrial activity, and financial services.
The Commodity Thesis (Bullish Brazil)
Brazil is a global commodity superpower — largest exporter of soybeans, coffee, sugar, plus a major producer of iron ore, oil, and increasingly rare earth minerals.
When global commodity demand strengthens, EWZ captures upside through Petrobras, Vale, and the banks financing commodity production. Brazil also offers higher dividend yields — the banking sector distributes significant earnings to shareholders.
Currency Dynamics
Both ETFs are unhedged. The Brazilian real tends to be more volatile than the Mexican peso, meaning EWZ can deliver outsized gains during BRL strengthening and outsized losses during depreciations.
When to Choose Which
The best answer for most investors is both. A barbell — holding EWZ and EWW together — gives you commodity upside and nearshoring exposure, with each fund partially hedging the other's sector risks.
