The Mexican peso could fall almost 9% to 21.30 per dollar next year if U.S. President Donald Trump again threatens the country during his re-election campaign, Mexican financial group Banorte said on Tuesday. Trump has repeatedly sent the Mexican currency and stock market tumbling after attacking Mexico over immigration and trade, mostly on Twitter, threatening to impose tariffs on Mexican goods or close the countries’ shared border. Banorte’s forecast would represent an 8.7% depreciation for the currency from its current level of about 19.60 pesos per dollar.
