Canada is the largest exporter of steel to the United States. The decline in the Canadian dollar has helped this trend imparticular. Trump is clueless when it comes to the impact of currency on foreign trade. If he wants to do tariffs, they MUST be indexed to the currency. Failure to do that will cause serious consequences as the dollar rises on the world financial markets in the years ahead.

I have stated many times that the entire system of trade is in a state of confusion. Following Bretton Woods, currencies were fixed to the dollar which in turn was fixed to $35 per troy ounce of gold. Therefore, the accounting system ONLY measured the amount of currencies moving back and forth. It was assumed that you imported more goods if the amount of outflow of the dollar increased. Consequently, the way we measure trade today has NOTHING to do with the actual amount of product moving internationally. If you spent more dollars but the dollar decline in value by 20%, then even an increase in imports measured in dollars at 20% was no change in the actual product. Welcome to the world of trade statistics!
