Global copper inventories on major exchanges have exceeded 1 million tonnes for the first time in more than two decades, reaching 1.012 million tonnes as of mid-February 2026, according to data compiled from the London Metal Exchange, U.S. Comex and Shanghai Futures Exchange.
The milestone marks the first time combined stocks have reached this level since 2004, when copper prices traded below $1.50 per pound. The current inventory buildup comes amid copper futures trading near $5.76 per pound for March delivery, approximately 12% below the peaks reached in late January.
Tariff-induced stockpiling in the United States and weakening demand from China, the world's largest copper consumer, are driving the inventory surge, market analysts said.
Tariff Policies and U.S. Stockpiling
U.S. copper inventories have expanded significantly over the past 13 months as importers rushed to bring material into the country ahead of potential tariff increases. Comex warehouses have absorbed substantial volumes, with traders and merchants building positions to hedge against policy uncertainty.
The stockpiling behavior began in early 2025 when the previous administration signaled intention to impose broader metals tariffs. Even as specific policy details shifted under the current administration, market participants continued accumulating inventory as a risk management strategy.
"The tariff overhang has created an incentive structure that encourages precautionary inventory builds," said Michael Chen, metals strategist at Goldman Sachs. "Companies are essentially prepaying for supply certainty."
U.S. copper imports increased 18% year-over-year in the fourth quarter of 2025, trade data showed, with much of that material flowing into exchange-registered warehouses rather than immediate consumption.
China Demand Weakens
China's copper consumption, which typically accounts for approximately 55% of global demand, has softened amid a slowing property sector and manufacturing headwinds. The country's refined copper imports fell 7% in January 2026 compared to the same month in 2025, customs data showed.
Chinese buyers have pulled back from spot markets, preferring to draw down existing inventories rather than purchase at current price levels. Shanghai Futures Exchange warehouses held 342,000 tonnes of copper as of Feb. 14, up from 287,000 tonnes at the start of the year.
"Chinese end-users are demonstrating price resistance above $12,500 per tonne," said Li Wei, analyst at Beijing-based consultancy Antaike. "The construction slowdown is particularly evident in copper-intensive infrastructure projects."
Chinese property starts declined 11% year-over-year in January, weighing on copper wire and cable demand. Manufacturing purchasing managers' indices have remained below the 50 expansion threshold for three consecutive months.
Price Pressure Mounts
Copper futures have retreated from the $6.54 per pound high reached Jan. 24, pressured by the inventory overhang and demand concerns. The metal rallied more than 40% through 2025, driven by supply disruptions and optimism about electric vehicle and renewable energy demand.
The current price of $5.76 per pound, or approximately $12,700 per tonne, represents a key technical level watched by traders. A sustained break below $5.70 could trigger additional selling, analysts said.
"The inventory data is unambiguous," said Sarah Martinez, head of base metals research at Citigroup. "We're looking at the largest visible stock pile since 2004, and that creates a natural ceiling for prices."
Three-month LME copper traded at $12,685 per tonne in afternoon London trading, down 0.8% on the day. Trading volumes were 15% above the 30-day average as position adjustments accelerated.
Surplus or Logistics Bottleneck?
Market participants disagree on whether the inventory buildup represents genuine oversupply or a temporary logistics phenomenon that will reverse as stockpiled material enters consumption channels.
Bulls argue that underlying supply-demand fundamentals remain tight, pointing to limited new mine supply and robust long-term demand from electrification trends. They characterize the inventory surge as a timing mismatch rather than structural surplus.
"This is a tariff distortion, not a fundamental surplus," said David Thompson, portfolio manager at Newmont Capital. "Once policy certainty returns and Chinese stimulus measures gain traction, these inventories will draw down quickly."
Bears counter that the 1 million tonne threshold signals that supply has outpaced demand by a wider margin than many anticipated. They point to weak smelter utilization rates and rising treatment charges as evidence of loosening fundamentals.
Satellite monitoring data from commodities intelligence firm Kayrros showed global copper smelter activity in January at its lowest recorded level in nearly a decade. The reading suggests refiners are reducing production in response to margin pressure and excess refined metal availability.
Treatment and refining charges, fees paid by miners to smelters, have risen to approximately $88 per tonne and 8.8 cents per pound respectively, up from $78 per tonne and 7.8 cents per pound in December. Higher charges typically indicate improved availability of copper concentrate.
Historical Context: The 2004 Comparison
The last time copper exchange inventories exceeded 1 million tonnes, the global supply-demand picture looked markedly different. In 2004, China was still ramping up its infrastructure boom, copper prices traded below $1.50 per pound, and annual global consumption stood at approximately 16 million tonnes.
Current annual copper consumption exceeds 26 million tonnes, meaning the 1 million tonne inventory represents a smaller percentage of total demand than in 2004. Exchange stocks now represent roughly 14 days of global consumption, compared to approximately 23 days in 2004.
"The absolute tonnage comparison is less meaningful than the days-of-consumption metric," said James Parker, analyst at Wood Mackenzie. "By that measure, we're not in unprecedented territory."
However, the rapid pace of inventory accumulation has caught many market participants off guard. Stocks have risen approximately 320,000 tonnes since October, a pace not seen since 2009 during the global financial crisis.
Supply-Side Constraints Persist
Despite the inventory buildup, copper mine supply faces ongoing challenges that could tighten the market in coming quarters. Major mining regions in Chile and Peru have experienced production disruptions related to community relations, permitting delays and grade decline.
Chile, the world's largest copper producer, saw output fall 3.2% in 2025 to 5.3 million tonnes. Peru's production declined 1.8% to 2.4 million tonnes. Combined, the two countries account for approximately 40% of global mined copper supply.
New project development remains constrained by capital discipline among major miners and extended permitting timelines. The industry's project pipeline contains fewer large-scale deposits ready for development than at any point in the past 15 years, according to S&P Global Market Intelligence data.
"The inventory surge masks ongoing supply-side fragility," said Rebecca Foster, mining equity analyst at BMO Capital Markets. "Mine supply growth isn't keeping pace with long-term demand trajectories."
Several analysts project copper will shift back into deficit conditions by the second half of 2026 as Chinese stimulus measures gain traction and U.S. tariff uncertainties resolve. Consensus forecasts point to a market deficit of approximately 180,000 tonnes for the full year 2026.
Market Outlook
The copper market faces a critical test in coming months as seasonal demand patterns typically strengthen into the second quarter. Chinese buyers historically increase purchases ahead of peak construction season in March through May.
If Chinese restocking fails to materialize or U.S. tariff policies crystallize in ways that deter further precautionary buying, inventories could continue building, pressuring prices below $5.50 per pound.
Alternatively, a pickup in Chinese activity combined with supply disruptions could rapidly draw down stocks, potentially sending prices back above $6.00 per pound.
"The market is at an inflection point," said Martinez of Citigroup. "The next 60 days will determine whether this is a temporary inventory glut or the start of a more extended period of surplus conditions."
