Mexican Markets Rally While Peso Weakens on Fed Policy Uncertainty

Trading Economics and Banco de México data show the Mexican peso weakened to 18.7513 per dollar as of September 3, marking a 0.12% decline from the previous session.

The currency traded between 18.6480 and 18.8631 on Tuesday, reflecting broad uncertainty over Federal Reserve policy and Trump administration tariff disputes.

Mexico’s S&P/BMV IPC index achieved its third record high of 2025, closing at 59,747.88 points on September 2 with a 1.50% gain.

The benchmark surpassed its previous all-time high of 59,822.81 points reached earlier this year. Industrias Peñoles led the charge with a 7.26% surge to 655.07 pesos, benefiting from gold and silver reaching multi-year highs.

The dollar index (DXY) strengthened to 98.4363, gaining 0.12% as bond markets experienced significant turbulence. Thirty-year Treasury yields climbed to 4.97%, their highest level since 1998, pressuring risk assets globally while supporting dollar strength.

Technical Analysis reveals the peso trading within a defined range between key support at 18.50 and resistance at 19.00. The 50-day exponential moving average near 18.65 has provided consistent resistance for several months.

The Mexican currency’s relative strength index shows neutral readings around 58, suggesting neither overbought nor oversold conditions. Volume patterns indicate institutional caution ahead of Friday’s U.S. employment report.

The four-hour chart displays a bearish divergence pattern, with the peso failing to make new lows despite dollar strength. Meanwhile, the Global Liquidity Index (yellow line on charts) shows declining momentum, suggesting reduced risk appetite among international investors.

Gold reached $3,534.52 per ounce while silver hit $40.76, its highest since 2011. Precious metals rallied on expectations the Federal Reserve will cut rates September 17, with markets pricing a 92% probability of a 25 basis point reduction.

Market Fundamentals center on Trump’s legal battle over tariff authority. A federal appeals court ruled most of his tariffs illegal, though they remain effective until October 14 pending Supreme Court review.

The administration announced plans to seek expedited review, adding uncertainty to trade relationships with Mexico and other partners. Banco de México maintains its policy rate at 7.75% following a 25 basis point cut in August.

Governor Jonathan Heath dissented, preferring no change due to persistent inflation concerns. Core inflation remains above target at 4.23%, though headline inflation dropped to 3.51% in July.

Top Performers in Mexican equities included Promotora y Operadora de Infraestructura (+4.26%) and Banco Del Bajio (+3.02%). Losers featured Becle (-2.49%), Megacable (-1.15%), and Arca Continental (-1.04%).

The peso’s year-to-date performance shows a 10.11% decline against the dollar, though it strengthened 0.70% over the past month. Remittance flows, a key peso support, declined approximately 5% this year, removing structural tailwinds that supported the currency earlier in 2025.

Wall Street closed sharply lower Tuesday, with the S&P 500 falling 0.69% and Nasdaq dropping 0.82% as investors weighed tariff uncertainties. European markets also declined 1.47% on rising bond yields and fiscal concerns across major economies.

The Mexican stock market’s resilience contrasts sharply with global equity weakness, positioning it as an emerging market outlier.

However, analysts warn that corporate earnings challenges may test this optimism as companies report second-quarter results amid currency headwinds and slower economic growth.
