Copper prices surged to record levels in New York. They also approached all-time highs in London. Mounting fears of US import tariffs triggered aggressive metal inflows into American warehouses, tightening global availability.
Comex Surge and Arbitrage Dynamics
Comex copper for September delivery climbed up to $6.7270 per pound. That equals approximately $14,830 per tonne. It eclipsed previous mid-month peaks and maintained a sharp premium over London contracts. Meanwhile, LME three-month copper hovered near record territory at over $14,250 a tonne. This price disparity between transatlantic hubs has incentivized traders to redirect physical shipments toward American storage facilities.
Inventories in Comex-approved warehouses have expanded for dozens of consecutive sessions. They surged past record thresholds as participants hedged against policy shifts. The steady influx into the United States drained visible stocks across European and Asian hubs. This reduced the forecasted global surplus into a tighter deficit reality.
Trade Policy Pressures and Structural Deficits
Washington evaluates proposed import duties on refined copper of up to 15% heading into 2027. Duties step up further in subsequent years, acting as the primary catalyst for inventory accumulation. US refined copper imports maintained a historic pace, driven by commercial positioning. Major analytics firms note that the projected global surplus transformed into a deficit market due to regional hoarding.
Mining majors like Southern Copper and Freeport enjoyed substantial equity rallies, outperforming broader industrial benchmarks. However, supply vulnerabilities persist elsewhere, such as operational disruptions at the Kamoa-Kakula mine in the Congo. As policy uncertainty dominates trading floors, market participants remain focused on macroeconomic signals and regulatory announcements from Washington.

SuperMetalPrice Commentary:
The ongoing copper price rally highlights how prospective trade policies can radically distort traditional supply-demand balances, turning regional inventory accumulation into a global scarcity driver. Until US tariff certainty is established, transatlantic price arbitrage will continue to dictate physical trade flows and support elevated valuations across base metal markets.
