A U.S. economy praised for its surprising resilience to a pandemic, high inflation, and rapid interest rate hikes faces a new challenge from President Donald Trump's self-declared trade war, seen by economists as a recipe for fewer jobs, slower growth, and higher prices. The fallout, assuming Trump does not backtrack in the face of falling stock markets and cracks to consumer and business sentiment, is expected to be broad, deep and time-consuming as the world's largest economy adjusts to the overnight shock of a 25% tariff on most goods coming from Mexico and Canada, both close trading partners and geographic neighbors, and an additional 10% duty on imports from China. Canada and China have announced retaliatory tariffs on U.S. imports, while Mexico is expected to do so this coming weekend.
