Trump's US copper tariffs halt speculative market rally

President Donald Trump's impending 50% tariff on US copper imports has dramatically cooled a previously heated speculative rally in the metal markets. The announcement has effectively eliminated the profitable arbitrage opportunity that saw investors aggressively buying copper in Europe and Asia for resale in the United States. With shipping times stretching several weeks, companies now face the risk of their shipments being caught by the new duties.

Market tensions escalated further following US Commerce Secretary Howard Lutnik's announcement that the tariff investigation was concluding. According to Bloomberg analysis, this development means new copper shipments heading to American markets will soon face substantially higher costs.

The London Metal Exchange (LME) has seen a marked decrease in trader interest for immediate copper deliveries. The price differential between short-term and long-term contracts has narrowed significantly, reflecting reduced shortages in storage facilities that had previously reached record levels due to massive US-bound exports.

Bloomberg concludes that the cooling effect has ended the US price surge driven by excessive demand, with global markets now normalizing.
