Mexico’s Peso and Equities Endure Rate Cut and Trade Questions in Subdued Week

In the week ending August 11, 2025, Mexico’s markets moved carefully through a maze of global and domestic events. The central bank, Banco de México, lowered its main interest rate by 25 basis points to 7.75% after headline inflation slowed to 3.51% in July.

This decision signaled hope for economic relief, yet officials warned that persistent core inflation and external uncertainty—especially pressure from the United States—limit how far rates can fall.

After Banxico’s move, the Mexican peso gained slightly. The USD/MXN exchange rate dropped from 18.89 at the week’s start to 18.57 by week’s end. Chart signals confirmed this: the key 50- and 200-day moving averages became resistance at about 18.70 to 18.75.

The chart’s Relative Strength Index hovered near 40, showing traders remained cautious, while lower volatility and a flattening momentum gauge pointed to little excitement. Support at 18.53 held up after several tests.

The S&P/BMV IPC, Mexico’s benchmark stock index, stayed flat. The index hit a high near 58,325 on August 5 but closed the week around 58,070.

Over the month, the market is up about 2.4%, and on the year it is still 9.5% higher. Still, big exporters lost traction after the White House announced new tariffs.

While Mexico avoided the harshest penalty—an auto tariff delay—existing duties on steel, aluminum, and agriculture stayed in place, dulling prospects for top listed companies. Defensive sectors like banking and local consumer firms fared reasonably well.

Technical chart patterns confirm the stock market’s hesitancy. The index stayed above a major support of 57,900 and its long-term average, but momentum indicators showed little conviction for a fresh rally. Volatility indicators tightened, matching the week’s lack of direction.

Beyond domestic news, international cash flows to Mexican markets slowed. The Global Liquidity Index, drawn from the charts, slipped lower—meaning fewer dollars from abroad reached Mexican assets, putting added pressure on both markets and policymakers.

Behind the surface, the story is one of resilience against headwinds. Lower inflation finally gave Banxico room to cut rates, but the relief was muted by outside trade risks and shrinking foreign interest.

For local firms, it meant holding their ground rather than breaking out. For investors, it required caution as neither fresh optimism nor deep fear took hold. Technical supports held, but the search for a catalyst continues.

Mexico’s market message was clear: steady, but wary, with global events dictating the pace more than ever.
