[Watcher Guru] JUST IN: President Trump threatens to immediately double tariffs on Mexico if it does not stop migrant "caravans."

President Trump threatened to immediately double tariffs on Mexico unless it halts migrant "caravans," escalating trade tensions between the two economies. The warning implies existing levies on Mexican goods could rise to as much as double their current level, though the article did not specify the exact rates or product scope affected. The move matters because Mexico is one of the largest U.S. trading partners, and higher tariffs could ripple through supply chains, input costs and cross-border volumes. Markets will watch whether the threat translates into formal tariff action and whether Mexico responds with border enforcement measures or retaliatory trade steps.
