On August 1, US President Donald Trump surprised global markets by imposing a 50% tariff on all imported copper, citing national security concerns. Investors saw prices surge and volatility spike, sparking a debate on the strength of global supply chains for this essential metal.
Market Reaction: Prices Surge and Volatility Spikes
The tariff announcement sent COMEX copper futures up 13%, climbing to $5.61 per pound in Asian trading. Traders warn that the price jump could ripple through manufacturing, construction and clean-energy sectors across the G20.
Structural Supply Shortfall in the US
Analysts say the US faces a long-term copper deficit. "The US remains structurally short on copper," says Ole Hansen, head of commodity strategy at Saxo Bank. US Geological Survey data shows 2024 copper mine output at just 1.1 million metric tonnes—only 4.8% of global production and down 3% year on year.
Global Impact on Manufacturing and Green Tech
Copper is the backbone of power grids, electric vehicles, semiconductors and renewable-energy infrastructure. With nearly half of US demand met by imports, higher tariffs could drive up costs for EV startups, sustainable infrastructure projects and tech manufacturers worldwide.
The Preemptive Stockpiling Effect
Before the tariff takes effect, importers rushed to stockpile copper. In H1 2025, the US imported an estimated 881,000 metric tonnes of copper, almost double the domestic requirement of 441,000 tonnes, according to Macquarie. Once the tariff kicks in, this stockpile may unwind, reshaping pricing trends and trade flows.
What Comes Next?
Marcus Garvey, Macquarie’s head of commodities strategy, notes that the exact levy details—tariff rates, product scope and any grace periods—will determine the long-term fallout. For young entrepreneurs, tech startups and sustainability advocates, this policy shift is a real-world case study in how trade policy can reshape project costs, supply chains and global partnerships.
