Trump threatens Mexico with tariffs: He will double the rates

President Donald Trump threatened to double tariffs on Mexican goods if Mexico does not halt migrant caravans heading toward the U.S. border, escalating trade pressure on America's largest trading partner. The warning, announced without a specific timeline or rate figure, builds on existing tariff measures tied to immigration enforcement. The move matters because Mexico is a top U.S. trade partner, and higher duties could raise costs for importers and consumers across sectors including autos and agriculture. Investors should watch for formal tariff announcements, Mexican government responses, and whether the threat disrupts ongoing USMCA trade flows.
