U.S. President Donald Trump said his proposed additional 100% tariff on Chinese goods is unsustainable, but blamed Beijing for the stalled trade negotiations, which began after the U.S. imposed tighter controls on rare earth exports.
Trump also confirmed in an interview with Fox Business on Friday that he will meet Chinese President Xi Jinping in two weeks in South Korea—a meeting he had cast doubt on last week—and even expressed admiration for the Chinese leader.
Market Projections – Mexican Peso
Meanwhile, markets continue to price in the possibility of another Fed rate cut at the October 29 meeting. St. Louis Fed President Alberto Musalem said he is currently inclined to support a reduction at the upcoming policy decision.
Looking ahead to the overnight session, analysts expect a trading range of 18.34 to 18.47 pesos per dollar, citing lower risk aversion and the peso’s resilience as investors await greater clarity on tariffs over the weekend.
The dollar’s weakness over the week provided moderate support to the peso. Today’s close, compared to 18.5424 pesos per dollar last Friday, left the local currency with an accumulated gain of 15.25 centavos, or 0.82%.
