Mexican Peso tumbles on trade war fears, US high yields boost USD

• Mexican Peso weakens as Trump eyes copper tariffs, trade tensions escalate
• USD/MXN climbs past 20.50 as US Treasury yields rebound.
• US Treasury Secretary Bessent warns of economic fragility and supports tariffs as a revenue source.
• Mexico’s Balance of Trade and jobs data are in focus amid rising trade policy uncertainty.

The Mexican Peso (MXN) begins Wednesday's session on the backfoot against the US Dollar (USD) as US Treasury bond yields recover, underpinning the Greenback. The United States (US), imposing tariffs on its allies and adversaries, continued to grab the headlines, while US Treasury Secretary Scott Bessent noted the economy is “fragile.” At the time of writing, the USD/MXN pair trades at 20.51, up 0.24%.

A possible trade war spurred by US President Donald Trump keeps the Mexican Peso heavy. He had set his sights on copper and directed the Commerce Department to examine copper tariffs, with Mexico being one of the country's top importers. Meanwhile, US Treasury Secretary Bessent echoed some of his comments, saying that tariffs would be a source of revenue for the government.

Bessent warned that the economy is more fragile than economic indicators suggest, mentioning interest rate volatility, stickier inflation and reliance on government-sponsored job growth.

In the meantime, an absent economic docket in Mexico keeps USD/MXN traders leaning on dynamics linked to trade policies between the US and Mexico. Mexico’s Secretary of Commerce, Marcelo Ebrard, said that his first meeting with his counterpart, Howard Lutnick, was used to set the ground and establish general ideas about the importance of trade between both countries.

This week, Mexico’s docket will feature the Balance of Trade data for January alongside jobs data.

USD/MXN technical outlook: Mexican Peso drops as USD/MXN hurdles 50-day SMA

USD/MXN remains upward biased, and once it surpasses the 50-day Simple Moving Average (SMA) at 20.45, the path toward clearing 20.50 is on the cards. The Relative Strength Index (RSI), above 50, hit its highest peak in February, an indication that momentum favors buyers. They must clear the January 17 high of 20.93, followed by 21.00 and the year-to-date (YTD) high of 21.28.

Conversely, if USD/MXN struggles at the 50-day SMA, it could drop to the 100-day SMA at 20.24. On further weakness, the pair might surpass that dynamic support and head towards the 20.00 figure.
