NextFin News - Copper prices climbed in New York and London on Monday as the global metals market entered a high-stakes countdown toward a June 30 deadline for the Trump administration’s decision on refined copper tariffs. The red metal rose to $6.40 per pound on the COMEX in early Monday trading, a 0.6% gain that extends a month-long rally of more than 10%. This price action reflects a market increasingly positioned for a shift in U.S. trade policy that could fundamentally alter the flow of industrial metals into North America.
The current volatility centers on a pending report from Commerce Secretary Howard Lutnick, who is scheduled to provide U.S. President Trump with an update on the domestic copper market by the end of June. While the administration confounded market expectations last July by imposing tariffs on copper products but exempting refined metal, the White House has since signaled the potential for a phased-in approach. Under a Section 232 national security framework, the administration has flagged the possibility of a 15% tariff on refined copper starting in 2027, rising to 30% by 2028.
Andy Home, a veteran metals columnist at Reuters, noted that the market is currently engaged in a "round of tariff roulette" similar to the nervous anticipation seen exactly one year ago. Home, whose analysis often focuses on the structural shifts in exchange inventories, observed that the premium for U.S. delivery is once again widening. This arbitrage has triggered a massive migration of metal; COMEX-approved warehouses now hold 577,385 tons of copper, representing 44% of global exchange inventory—a 550% increase since the Section 232 investigation was initiated in early 2025.
The concentration of global stocks in the U.S. suggests that physical traders are front-running potential trade barriers. According to the World Bureau of Metal Statistics, U.S. inbound shipments more than doubled year-on-year to 533,000 tons in the first quarter of 2026. This surge in imports has paradoxically increased U.S. import dependency to 57%, up from 45% in 2024, according to U.S. Geological Survey data. While the administration’s stated goal is to reinvigorate domestic production, the U.S. still operates only two primary copper smelters, leaving the manufacturing sector highly vulnerable to price spikes if import costs rise.
Skeptics of the tariff-driven rally argue that the U.S. has already built a "strategic stockpile" that may mitigate the need for immediate protectionist measures. With over one million tons of copper currently sitting in U.S. ports and warehouses—a reserve larger than any country except China—some analysts suggest the market may be overestimating the likelihood of a 30% levy. If U.S. President Trump again chooses to exempt refined metal to protect downstream manufacturers from rising costs, the current CME premium could implode, repeating the "taco hedge" collapse seen in late 2025.
The outcome remains tethered to the administration's broader "Make America Healthy Again" and national security priorities. As the June 30 deadline approaches, the spread between the COMEX and the London Metal Exchange will serve as the primary barometer for trade expectations. For now, the market is betting that the administration will prioritize domestic smelting capacity over the immediate cost concerns of copper consumers, keeping the metal on a bullish trajectory as the month begins.
