NEW YORK, August 18, 2026, 6:09 p.m. EDT
- EWW ended the session at $74.46, slipping 0.60%, with intraday movement ranging from $74.32 to $75.28.
- At 6:07 p.m. EDT, USD/MXN was at 17.055, just 0.49% higher than its 52-week low.
- On Tuesday, Mexican stocks outperformed the wider emerging markets by 2.34 percentage points.
The iShares MSCI Mexico ETF NYSEARCA:EWW slipped 0.60% on Tuesday, but Mexico’s robust peso shielded the fund from the sharper declines seen in broader emerging markets. EWW finished at $74.46, while the iShares MSCI Emerging Markets ETF NYSEARCA:EEM posted a 2.94% drop. The 2.34-point difference marked the most notable market indicator behind an uptick in U.S.-dollar searches.
The currency move contrasts with a straightforward dollar rally. USD/MXN reached 17.055 at 6:07 p.m. EDT, marking a 0.15% increase from Monday’s close at 17.030—translating into a slight daily decline for the peso. However, the dollar has fallen 1.99% over the past 20 sessions and dropped 8.55% across the most recent 252 trading sessions.
The extended rally is significant for a U.S.-dollar fund invested in Mexican equities. When the peso strengthens, it increases the dollar valuation of peso-denominated assets, assuming other factors remain constant. EWW climbed 21.57% over 252 sessions, far surpassing Tuesday’s closing decline.
Tuesday cross-asset snapshot
| Instrument | Close | Aug. 18 move | 2026 move | Volume |
|---|---|---|---|---|
| iShares MSCI Mexico ETF (EWW) | $74.46 | down 0.60% | up 6.89% | 2.44 million |
| iShares MSCI Emerging Markets ETF (EEM) | $65.34 | fell 2.94% | rallied 16.18% | 20.59 million |
| iShares Latin America 40 ETF NYSEARCA:ILF | $33.23 | dropped 1.22% | gained 7.78% | 3.12 million |
| SPDR S&P 500 ETF Trust NYSEARCA:SPY | $767.45 | slipped 0.68% | rose 12.34% | 43.24 million |
Trading activity was elevated. EWW saw volume of 2.44 million shares, roughly double its 30-session average of 1.21 million. The fund lagged the S&P 500 by only 0.08 point, even as emerging markets saw a selloff.
The dollar traded within a narrow band as weaker U.S. data led markets to price in a 70% probability that the Federal Reserve will hold rates steady in September. Eugene Epstein, head of structured products at Moneycorp North America, noted that dollar pairs were influenced by a dovish interpretation of the most recent Fed meeting.
Holdings investors access via EWW
| Sector | Portfolio weight | Currency sensitivity |
|---|---|---|
| Materials | 25.45% | Commodity pricing helps balance peso effects |
| Consumer staples | 24.83% | Driven by local consumption and import costs |
| Financials | 17.38% | Margins and credit appetite linked to rates |
| Industrials | 11.83% | U.S. demand and trade remain influential |
| Communication | 10.46% | Cash flows are primarily domestic |
The fund’s exposure by sector positions the peso as a strong yet partial catalyst. Materials and staples account for 50.28% of total assets. Price moves in metals, shifts in consumer demand and corporate results can easily outweigh translation gains at any moment.
Analyst outlooks and predictions
| Analyst source | Recommendation or forecast | Date published | Read-through at USD/MXN 17.055 |
|---|---|---|---|
| Reuters poll, 35 economists | 34 saw Banxico keeping 6.50%; one predicted 25-bp reduction | Aug. 4, 2026 | Expectation to hold was accurate |
| Reuters poll median, 28 economists | 6.50% rate seen lasting through end-2026 | Aug. 4, 2026 | Strong backing for rate stance |
| Goldman Sachs | Sees no change to rates through the remainder of 2026 | Reported Aug. 6, 2026 | Carry outlook positive, but growth risk increases |
| UBS | Forecasts USD/MXN at 18.2 in Q4 2026 | Nov. 21, 2025 | Spot rate now 6.3% under projection |
On August 6, Banxico kept its key interest rate unchanged at 6.50%. The central bank’s board pushed back its anticipated timeframe for reaching 3% inflation to the end of 2027. While the high rate offers support to the peso, it maintains tight lending conditions at home.
The current exchange rate exceeds previous projections. USD/MXN stands at 17.055, which is 6.3% under UBS’s fourth-quarter projection of 18.2. It is also 9.9% below the 18.92 median 12-month outlook from a December Reuters survey. A lower USD/MXN indicates a firmer peso.
Risks: Surges in oil prices, trade tensions between the U.S. and Mexico, or another uptick in the dollar may erode the currency buffer. EWW is also highly concentrated, with roughly 90% of assets in its top five sectors.
The upcoming test is if USD/MXN remains close to 17 as long as EWW trades above the $74.32 low from Tuesday. A move beyond these levels would indicate if currency support continues to counter the fund’s equity and sector exposure.

Policy and forecast gap
The peso cushion limited EWW's loss during a broad emerging-market selloff. The setup weakens if USD/MXN moves decisively away from 17 or if EWW breaks Tuesday's $74.32 low.
