Banxico Policy vs. US Credit Woes: How the Mexican Peso Capitalized on Dollar Weakness

The Mexican Peso strengthened significantly against the US Dollar on Monday, May 19, 2025, with the USD/MXN exchange rate closing at 19.3198 pesos per dollar, representing a gain of 15.48 centavos or 0.80% for the peso compared to Friday’s close of 19.4746.

During the trading session, the pair moved within a range between a high of 19.4924 and a low of 19.2995 pesos. The USD/MXN is currently trading at 19.32 after hitting a daily high of 19.48 earlier in the session.

This represents a notable decline from the previous week’s levels, with the pair continuing its downward trajectory that began in early April when it peaked above the 21.00 level.

According to the latest data, the US Dollar to Mexican Peso exchange rate stood at 19.46 as of May 19, down from 19.49 the previous market day, representing a change of -0.16% day-over-day.

Year-over-year, however, the dollar has strengthened significantly against the peso, up 16.65% from 16.68 one year ago.

Key Market Drivers

Moody’s US Credit Rating Downgrade

The primary catalyst for today’s peso appreciation was Moody’s surprise downgrade of the US government’s credit rating from AAA to AA1.

The international rating agency cited that “inaction by successive US administrations and Congress has contributed to the country’s worsening fiscal position, raising concerns over long-term debt sustainability”.

This news triggered broad-based dollar weakness, with the US Dollar Index (DXY) falling 0.71% to 100.37 points.

Banxico’s Monetary Policy Stance

Market participants continue to digest the implications of Banco de Mexico’s (Banxico) recent monetary policy decisions. The central bank unanimously reduced its benchmark interest rate to 8.50% last Thursday (May 15), marking the seventh consecutive rate cut.

Despite these cuts, Banxico Governor Victoria Rodriguez Ceja maintained a dovish tone but indicated that the central bank will maintain a restrictive monetary stance for now.

Economic Data Concerns

Mexico’s National Statistics Agency warned that the economy likely stalled in April, according to the Timely Indicator of Economic Activity.

This economic uncertainty has added another dimension to the peso’s trading dynamics, though it appears to have been overshadowed by the broader dollar weakness today.

Technical Analysis

From a technical perspective, USD/MXN has broken below its multi-session consolidation zone, slipping beneath the key support band between 19.40 and 19.46, which had previously contained price action since mid-April.

The pair is now trading below the 20-day Simple Moving Average (SMA) at 19.55 and under the 78.6% Fibonacci retracement level of the October–February rally at 19.578, reinforcing the prevailing bearish momentum.

The Relative Strength Index (RSI) at 38.27 confirms weakening momentum, suggesting sellers remain in control unless the pair reclaims resistance at 19.46.

Analysts note that USD/MXN remains downward biased, with sellers eyeing the year-to-date (YTD) lows of 19.29 hit on May 14, which, once cleared, could pave the way for further downside toward the 19.00 figure, last hit on August 21, 2024.

Market Outlook

Traders are now focusing on upcoming economic data releases, particularly Mexican Retail Sales and Gross Domestic Product (GDP) figures due later this week. On the US front, investors will be digesting the S&P Global Flash PMI figures, as well as housing and jobs data.

The interest rate differential between Mexico and the US continues to support the peso, despite recent rate cuts by Banxico. While the differential isn’t as wide as it historically has been, Mexico’s interest rates remain significantly higher than those in the US, making the peso attractive for carry trades.

Gov.Capital’s forecast suggests a continued bearish outlook for USD/MXN, projecting the pair to decline to 19.28974 by May 19, 19.21655 by May 20, and potentially reaching 17.52349 (-14.87%) after a year.

Trade and Geopolitical Factors

Trade relations between the US and Mexico continue to influence the currency pair. There has been “continued progress by the USA in drumming up new trade and trade deals to replace proposed tariffs,” including memorandums signed with Saudi Arabia, Qatar, and the UAE.

However, statements from the US Treasury Secretary last week “reignited concerns about potential new tariffs on Mexican exports,” adding another layer of uncertainty to the peso’s outlook.

As the trading day concludes, the Mexican Peso has demonstrated resilience against the US Dollar, capitalizing on broader dollar weakness following the Moody’s downgrade while market participants continue to monitor domestic economic developments and central bank policy for further directional cues.
