LME three-month copper traded around $13,330 per tonne on July 3, consolidating after a sharp sell-off on July 1 that wiped $700/t intraday when no tariff decision materialized from the June 30 Commerce Department deadline. The metal remains up roughly 43% year-over-year and is trading well within the elevated $10,000–$14,500 band that has defined 2026, but the mood has shifted from conviction to wait-and-see. The record $14,527/t set in January feels distant, yet the structural story — tight mine supply, energy transition demand, a COMEX-LME arbitrage that won't close — remains intact.
The tariff countdown has been the dominant price driver all year. Under the Section 232 investigation launched in 2025, the Commerce Department was legally required to submit its recommendation by June 30, 2026. As of July 3, the White House has not acted. The market is now trading on probabilities: a phased tariff of 15% on refined copper in 2027 rising to 30% in 2028 is the base case among analysts, but the administration is keeping options open. ‘Strategic ambiguity’ is the phrase analysts at Goldman Sachs use — the White House benefits from keeping US buyers stockpiling, which supports domestic production incentives without the political cost of a new consumer-facing tariff.
The stockpiling has been extraordinary. COMEX copper inventories have surged to approximately 650,000 tonnes, accounting for 44% of all exchange-held copper globally. US refined copper imports doubled year-over-year in the first quarter of 2026 to 533,000 tonnes, according to World Bureau of Metal Statistics data. Meanwhile, LME copper stocks have fallen to 352,100 tonnes, the lowest in three months. The COMEX-LME spread has repeatedly breached $500/t and hit nearly $690/t in early June. This is not demand-driven buying. It is inventory pre-positioning ahead of a tariff that may or may not arrive. Red Cloud Securities strategist Ken Hoffman told S&P Global: ‘Copper and really all metal prices are being driven by global uncertainty brought on by US Government actions that have caused a huge increase in copper flows to the US, not due to demand, but for inventory stocking.’
The physical market outside the US tells a more sobering story. Chinese demand, which accounts for 58–60% of global copper consumption, is soft. The dramatic decline in China's import premium signals that high prices are hurting downstream users. StoneX senior analyst Natalie Scott-Gray told S&P Global that the refined copper deficit of 333,000 tonnes forecast for 2026 — while real — represents less than 2% of global demand. ‘We don’t see a deficit of 333,000 tonnes as hugely out of balance,’ she said. StoneX forecasts 2026 LME copper averaging $11,490/t, well below current spot levels. S&P Global's own forecast is just above $12,100/t for the full year, but the firm warns the current elevated price is ‘overextended’ relative to physical fundamentals.
Goldman Sachs has moved in the opposite direction to most forecasters. The bank raised its year-end 2026 LME copper target to $13,735/t from $12,465/t in early June, and warned prices could surge past $14,000/t in the second half if refined tariffs are imposed and a new wave of US stockpiling begins. The bull case rests on four legs: a refined copper tariff triggering another buying panic; continued mine supply constraints (the cumulative concentrate deficit is projected at ~3 million tonnes by 2036); AI and data-center build-out driving incremental demand; and Iranian conflict fallout boosting metals broadly through defense and electrification spending.
J.P. Morgan's models add a cautionary note on energy prices. The bank estimates that if Brent crude sustained above $110/bbl for the rest of 2026, copper demand growth could be stripped by about 1.4 percentage points as economic growth slows. With Brent currently trading on Middle East risk premium, that variable is very much alive.
Chilean supply has disappointed. July 1 price action was partly driven by reports of slowing output from the world's largest copper producer, where aging mines and declining ore grades are a structural headwind. While Chile and Canada received exemptions from the Section 232 tariffs on concentrates and cathode, the broader supply picture is tightening. Mine disruptions across South America and Africa, combined with permitting delays for new projects, mean the concentrate market will stay tight for years.
The market is caught between two forces: a medium-term structural bull story that virtually every analyst agrees on, and a near-term price level that several respected houses — S&P Global, StoneX, Fastmarkets — warn is ahead of the fundamentals. LME speculative net long positioning sits in its 80th percentile. The unwind risk is real. If the refined tariff is delayed past 2027 or exempted entirely, the COMEX premium collapses, LME inventory flows reverse, and the price could retrace sharply toward $10,000–11,000/t.
The Section 232 decision isn't binary. Even a ‘no new tariff’ announcement leaves 50% tariffs on semi-finished copper products in place and 25% on copper-intensive derivatives. US buyers should lock in LME-based contracts now while the COMEX premium is still $500+/t — if refined tariffs arrive, the all-in US price rises immediately. Non-US buyers: the LME price includes a tariff risk premium of roughly $500–800/t above where pure supply-demand fundamentals would place it. Consider floating-price contracts indexed to LME with a collar at $11,500–14,500/t for H2 2026. If the tariff is delayed and COMEX-LME spreads normalize, expect a 15–20% correction in LME within 60 days. Position for volatility: the decision, when it comes, will move copper $1,000+/t in 48 hours.
