USA holds 1.1 million tons of copper: more than ever in strategic reserve

Copper stockpiles in the United States have reached approximately 1.1 million tons, exceeding record levels of the Cold War-era national strategic reserve — even from the early 1960s. The estimate comes from Citi analysts and was cited by Reuters. Washington spent not a dollar on this stockpile — copper is being accumulated by private market participants, not by the government.
