As traders worldwide wait to see if U.S. President Donald Trump once again holds off on putting new tariffs on Canada and Mexico, the head of the U.S. Treasury Department has highlighted one potentially promising avenue for America’s neighbors.

President Donald Trump said Thursday tariffs of 25% on Mexican and Canadian goods are set to take effect on March 4, while also threatening to impose an additional 10% on Chinese imports on the same date.

From the aluminum in beverage containers to the steel in vehicles, tariffs are expected to raise prices across the economy.
