Mexican Peso plunges as US-Mexico interest rate differential reduces

The Mexican Peso experienced a significant depreciation against the US Dollar on Monday, driven by market sentiment souring due to stalled US-Iran negotiations. Despite news reports suggesting an imminent agreement, officials denied any progress. The Bank of Mexico Governor, Victoria Rodriguez, declared that the exchange rate remains favorable for the Mexican currency.

The USD/MXN exchanged at 17.99, marking a 1.80% increase. Meanwhile, US President Trump refuted claims that the US offered sanctions relief to Iran, further fueling the uncertainty. As US Treasury yields surged, the Greenback gained strength, with the US Dollar Index (DXY) rising 0.14% to 101.17. Fed Governor Lisa Cook cautioned of persistent inflationary pressures, highlighting AI advancements and Middle East strife.

Banxico's Governor Rodriguez Ceja stated at an interview with El Financiero that the peso's depreciation, relative to previous levels, does not present additional pressures beyond those already considered in the inflation projections, which anticipate a gradual decrease toward a 3 percent target. Geopolitical conflicts heighten uncertainty, and Banxico refrained from offering forward guidance on the main reference rate, emphasizing that monetary policy will not mechanically adjust to Fed funds rate changes.

Money markets indicated a 92% chance that Banxico would maintain the 6.50% interest rate for the November 5 meeting, according to Prime Terminal. The US economic calendar includes key data such as JOLTS job openings, ADP Employment Change, the Core PCE Price Index, and September's Nonfarm Payrolls. The USD/MXN chart exhibited bullish momentum after breaking key Simple Moving Averages, including the 200-day SMA at 17.41.

The RSI turned overbought, nearing extreme conditions. The next resistance level is at 18.00, followed by the year-to-date high of 18.16 and the November 21, 2025, high of 18.53. Above that, the 19.00 level represents the next key resistance. The Mexican Peso, influenced by factors such as economic performance, central bank policies, foreign investment levels, and remittances, stands as the most traded Latin American currency.

Its value is also impacted by geopolitical trends, including nearshoring and oil prices, given Mexico's central role as a manufacturing hub and oil exporter in the continent. The Bank of Mexico, or Banxico, aims to maintain low and stable inflation, typically set at 3%. To achieve this, the bank sets appropriate interest rates. Higher rates make the Mexican Peso more attractive to investors, while lower rates weaken it.

Macroeconomic data releases significantly affect the Mexican Peso's valuation, with strong economic growth, low unemployment, and high confidence attracting foreign investment and potentially prompting Banxico to raise interest rates. Conversely, weak economic data may lead to MXN depreciation. As an emerging-market currency, the Mexican Peso thrives during risk-on periods but weakens during market turbulence or economic uncertainty.
