The United States is crazily competing worldwide for copper.

Recently, American traders have started a craze for copper. As of May 29th, the copper inventories on the New York Mercantile Exchange had reached approximately 640,200 tons, setting a new record high. Goldman Sachs estimates that the supply gap for copper in markets outside the United States has surged to 640,000 tons. While copper is piling up in warehouses in the United States, there is a shortage of supply in non-U.S. regions. With a few major countries using tariff expectations to create cross-market price differentials and attract global copper resources to the United States, other countries are paying the price for their policy uncertainty.
