Mexican Peso slips as USD/MXN rises on mixed US data, Fed in focus

• Mexican Peso weakens as risk sentiment shifts ahead of the Fed rate decision on Wednesday.
• Tensions between Mexico and the United States remain in focus, but have limited market impact.
• USD/MXN extends gains as yields edge higher and traders reprice interest rate expectations.

Mexican peso softens as traders await Fed clarity

The Mexican Peso (MXN) is under pressure against the US Dollar (USD) in Tuesday's European session as markets brace for the Federal Reserve's (Fed) monetary policy decision on Wednesday. USD/MXN is up 0.24% on the day, trading near 19.75 at the time of writing, after breaking above a key trendline and extending gains from Monday.

The move reflects a shift in risk sentiment, as recent US data has challenged expectations for early interest rate cuts. With investors repositioning ahead of Fed Chair Jerome Powell's comments, demand for the US Dollar has strengthened while the Peso and other Emerging Market (EM) currencies have lagged.

USD/MXN rises on US data divergence, while US-Mexico tensions linger

The latest move higher in USD/MXN has been driven by mixed signals from the US services sector. On Monday, the Institute for Supply Management (ISM) Services Purchasing Managers Index (PMI) surprised to the upside, rising to 51.6 in April, above the 50.4 consensus and the 50.8 reading in the previous month, suggesting ongoing resilience in the services sector business activity.

In contrast, the S&P Global US Services PMI dropped to 50.8, missing the preliminary estimate of 51.4 and marking the slowest pace of expansion in two years. The divergence points to an uneven economic recovery, with larger firms likely performing better than smaller, internationally exposed businesses.

For markets, the ISM report carried more weight, helping lift US Treasury yields modestly and refocusing attention on the Federal Reserve's monetary policy path. Higher yields increase the appeal of the US Dollar, while risk-sensitive assets like the Mexican Peso tend to underperform.

Meanwhile, political tensions between Mexico and the United States remain in the background. 

Over the weekend, Mexican President Claudia Sheinbaum publicly rejected an offer by US President Donald Trump to deploy American troops in Mexico to fight drug cartels. Sheinbaum reaffirmed Mexico's sovereignty, stating: "We can work together, but you in your territory and us in ours."

Although the development has drawn diplomatic attention, markets have treated it as a background risk with limited direct impact on USD/MXN price action.

USD/MXN daily digest:  Monetary policy, growth, and trade risks

• The Federal Open Market Committee (FOMC) is expected to keep the benchmark interest rate steady in the 4.25%-4.50% range on Wednesday. However, market focus will be on the tone of Chair Jerome Powell's press conference for any signal on the timing of rate cuts.
• According to the CME FedWatch Tool, traders are pricing in a 25 basis-point (bps) rate cut in July, though expectations have eased slightly following Monday's ISM beat. A dovish tone from Powell could weaken the US Dollar and lift the Peso.
• The Bank of Mexico (Banxico) is expected to deliver another 50 bps cut at its next meeting on May 15. Mexican Q1 Gross Domestic Product (GDP) rose just 0.2%, narrowly avoiding recession, while inflation continues to cool. Banxico has maintained a cautious, data-driven approach.
• Recent US tariffs on key Mexican exports - including metals and autos - have added pressure to the external sector, weighing on trade and investment outlooks.
• Uncertainty surrounding global demand, commodity prices, and future US trade or immigration policy continues to cloud the outlook for emerging market assets like the Mexican Peso.

USD/MXN clears trendline, momentum builds toward 19.80

From a technical perspective, USD/MXN has broken above a descending trendline resistance drawn from the April high of 21.08, indicating a potential shift in short-term bias. 

The pair is now trading around 19.75, its highest level in nearly two weeks, and has reclaimed ground above the 10-day Simple Moving Average (SMA), now acting as immediate support at 19.61.

Momentum indicators are improving, with the relative strength index (RSI) approaching the neutral level of 50, suggesting downside momentum has faded. Resistance is now in focus at the psychological barrier of 19.80, followed by the 23.6% Fibonacci retracement of the April move at 19.85.

On the downside, the reclaimed trendline and the 19.59 - 19.60 zone offer initial support, with stronger support seen at the April low of 19.47.
