President Donald Trump said on Friday he plans to announce reciprocal tariffs on many countries by Monday or Tuesday of next week, a major escalation of his offensive to tear up and reshape global trade relationships in the U.

If Trump’s tariffs take effect next month, consumers are unlikely to see price increases until the current inventory is sold, according to Felipe Muñoz, a senior analyst at auto consulting firm JATO Dynamics. Across the industry, that could mean a roughly two-month buffer between tariffs starting and prices increasing at the dealership, Muñoz said.
