Selling pressure on the Mexican Peso persisted for a second consecutive day, leaving it more than 1.49% lower against the US Dollar and taking USD/MXN to 18.70, close to 11-month highs. Oil prices remain supported by the US-Iran conflict, raising the likelihood that the Federal Reserve might increase interest rates to contain high inflation.

The intensifying US-Iran conflict appears to be weighing on the Peso. According to recent reports citing a US official, the State Department is preparing an order requiring some personnel and family members to leave US embassies near the Persian Gulf.
While Iran is prepared to give diplomacy another chance, its Foreign Minister earlier warned that a US decision to go to war would lead to an even greater strategic failure. Separately, Fars reported that multiple explosions had been heard in Sirik, although the source and nature of the sounds remained unknown.
Heightened Middle East tensions typically prompt market participants to move out of risk-sensitive currencies, including the Mexican Peso, and seek the relative safety of the US Dollar.
A smaller interest rate gap between the US and Mexico also favours further gains in USD/MXN. By the end of 2026, the differential is set to shrink from 250 basis points to 200. The Fed is expected to raise rates in December, whereas analysts in the Citi Mexico Expectations Survey project that the Bank of Mexico (Banxico) will keep rates unchanged in 2026 and towards the end of 2027.
Although some matters were still unresolved, Mexico’s President Claudia Sheinbaum described a trade agreement with the US as “very close”. US President Donald Trump, her counterpart, also said that a “great trade deal with Mexico is very close.”
For Mexico, the development is encouraging: resolving trade and tariff disputes quickly with the US, its largest trading partner, would lend support to the Peso. The comments come after a Wall Street Journal report on 15 October said progress on tariffs and a trade agreement had stalled.
Mexico’s October Retail Sales and Mid-Month Inflation figures are next on investors’ radar. The US calendar includes jobless claims for the week ending 17 October, S&P Global Flash PMIs and the final October Consumer Sentiment reading from the University of Michigan.
A bullish near-term bias remains in place on the daily chart as USD/MXN trades at 18.6908, extending gains well beyond the latest cluster of three simple moving averages around 17.5087. The pair also remains comfortably above the earlier horizontal support at 16.8866. With the Relative Strength Index (14) elevated near 73, upward momentum looks strong but increasingly stretched as the price moves further from its medium-term averages.
If the pair retreats, the three simple moving averages around 17.51 offer the first support, ahead of the more distant horizontal level at 16.89 in the event of a deeper correction. There are currently no nearby mapped resistance levels to constrain the advance. However, the overbought RSI indicates that further gains from here could give way to consolidation or a retreat towards the 17.50 region before buyers seek another upward move.

Among Latin American currencies, the Mexican Peso (MXN) is the most actively traded. Broad influences on its value include Mexico’s economic performance, central bank policy, foreign investment inflows and remittances from Mexicans living overseas, especially in the United States. Geopolitical developments can affect MXN as well. Nearshoring, for instance, involves companies moving manufacturing capacity and supply chains nearer to their home countries. This is also viewed as a driver of the Mexican currency, given Mexico’s standing as a major manufacturing hub in the American continent. Oil prices are another influence on MXN because Mexico is a significant exporter of the commodity.
Keeping inflation low and stable is the primary mandate of Mexico’s central bank, Banxico. It aims for inflation at or near 3%, the midpoint of its 2% to 4% tolerance band, and sets interest rates accordingly. If inflation becomes too high, Banxico seeks to curb it through rate increases. Higher borrowing costs for households and businesses restrain demand and cool the broader economy. The Mexican Peso (MXN) generally benefits from higher interest rates, as the resulting rise in yields makes Mexico more attractive to investors. Lower rates, by contrast, usually put downward pressure on MXN.
By helping investors gauge the economy’s health, macroeconomic releases can influence the valuation of the Mexican Peso (MXN). Robust growth, low unemployment and strong confidence underpin a healthy Mexican economy, which is supportive of MXN. These conditions draw more foreign investment and may also prompt the Bank of Mexico (Banxico) to raise interest rates, especially when economic strength is accompanied by elevated inflation. Weak economic figures, on the other hand, are likely to lead to MXN depreciation.
Risk-on conditions generally favour the Mexican Peso (MXN), an emerging-market currency. When investors see broader market risks as low, they are more willing to take on higher-risk investments. During market turbulence or economic uncertainty, however, MXN tends to lose ground as investors exit riskier assets in favour of more stable safe havens.
