China's destocking eases global copper inventory pressure, while U.S. tariff frontrunning continues to support a bullish view on copper prices and mining equities

Overview

This report is a JPMorgan copper market dashboard focused on global copper inventories, U.S. tariff frontrunning, Chinese demand, mine supply, copper prices, and copper miner positioning. The report argues that global inventory pressure has eased because of China's destocking, but continued U.S. inventory accumulation means market structure is being significantly shaped by tariff policy and cross-market arbitrage. Over the medium term, tight mine supply and structural demand support remain in place, but with copper prices already at elevated levels, the key catalyst in 2H26 is no longer just supply-demand balance, but the path of U.S. Section 232 tariffs and their impact on the distribution of inventories inside versus outside the U.S.

Core views

The report's core views are: first, global visible inventories have fallen to 1.05Mt and non-U.S. inventories have returned to 2025 levels, showing that China's destocking has improved global inventory pressure; second, U.S. inventories continue to rise due to tariff frontrunning, reaching about 725kt and around 70% of the global total, creating a U.S. metal absorption effect akin to a strategic stockpile; third, China demand is flat year-to-date and global mine supply is growing only modestly, so fundamentals have not meaningfully loosened; fourth, price risk depends mainly on tariff certainty or whether higher future tariffs further drive U.S. stockbuilding or subsequent destocking; fifth, copper miner positioning remains tilted toward companies with copper volume growth, free cash flow improvement, and better ROCE.

Analysis framework

The report uses a dashboard approach combining inventories, prices, arbitrage, sentiment, the cost curve, regional supply and demand, mine production, and valuation across covered companies. Its analytical framework includes the relationship between global visible inventories and prices, U.S. inventories relative to the rest of the world, LME/COMEX/SHFE arbitrage windows, LME cancelled warrants, Chinese spot premiums, smelting treatment charges, regional mined copper output, global and Chinese refined copper supply and demand, long-term price ranges, Escondida mine tracking, and major producers' market shares.

Methodology notes

• commodity_market_dashboardIntegrated inventory-price-arbitrage tracking

  Assess the tightness of the copper market through global visible inventories, exchange inventory locations, cross-market spreads, and spot premiums.

  The report observes combined inventories across LME, COMEX, SHFE, and Chinese bonded warehouses, while distinguishing between U.S. and non-U.S. inventories to identify tariff-frontrunning-driven inventory migration rather than relying only on global total inventories to judge supply and demand.

• policy_catalyst_analysisSection 232 tariff scenario

  Treat the path of U.S. copper import tariffs as the core variable for prices and inventory distribution in 2H26.

  The report believes the U.S. may impose a 15% tariff on refined copper cathode imports from January 2027 and raise it to 30% in January 2028, with the intention of keeping imported copper in the U.S. as a key reserve.

• equity_research_ratingJ.P.Morgan OW/N/UW rating system

  Use Overweight, Neutral, and Underweight to express expected stock performance relative to covered peers.

  The report maintains OW on multiple copper mining stocks, prefers Freeport, and upgrades Antofagasta to OW; it maintains UW on Anglo American due to higher cost and business exposure risks.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Copper

  Core research target

  Strengths

  Inventory pressure is easing, non-U.S. inventories are tightening, mine supply remains tight, and policy catalysts may lift the price floor.

  Weaknesses

  Current prices are already high, around $13,600/mt and up more than 40% year-on-year, and are not cheap against a backdrop where the global refined market could be in surplus by more than 500kmt in 2025.

  Comparison

  Relative to underlying demand, the report believes China's buy-on-dips behavior and U.S. tariff frontrunning have greater explanatory power for prices.

  Risks

  Tariff outcomes, subsequent U.S. destocking, weaker-than-expected demand, substitution risk, and pullback from high prices.

• Freeport

  Preferred North American copper miner

  Strengths

  The report explicitly states a preference for Freeport in North America and assigns it OW.

  Risks

  Copper prices, costs, project execution, and policy-driven market volatility.

Key data

• Global visible copper inventories1.05MtDown from 1.37Mt in March, mainly driven by destocking in China's SHFE and bonded warehouses.
• Change in inventories at China's SHFE and bonded warehousesDown about 450kt to around 120ktThe report says this was the main driver of easing global inventory pressure.
• U.S.-related LME and COMEX inventoriesAbout 725kt, around 70% of the global totalU.S. inventories continue to build, reflecting ongoing tariff frontrunning.
• China demandBroadly flat year-to-date through MayHigher refined output was offset by lower imports.
• Global mined copper outputUp 1.4% year-to-date through AprilMine-side supply growth is modest.
• Copper priceAbout $6-6.2/lb, up about 8% year-to-dateThe report argues that China's buy-on-dips behavior and U.S. tariff frontrunning are the stronger price drivers.
• J.P.Morgan medium-term price viewAround the current level of $13,600/mt; the upper bound may be pushed to $15,000/mtGreg Shearer's team believes policy rather than supply-demand balance is the key catalyst in 2H26.
• Potential U.S. tariff path15% in January 2027, 30% in January 2028The report believes a phased Section 232 refined copper cathode import tariff may be adopted.

Impact & implications

For investors, the report implies that in the short term copper prices and copper mining equities are more influenced by policy, inventory location, and arbitrage behavior than by the single variable of traditional supply-demand balance. If the U.S. tariff path becomes clearer and continues to attract metal inflows into the U.S., non-U.S. inventories may tighten further, supporting a higher price floor; if destocking occurs after tariffs are implemented or policy falls short of expectations, price volatility risk could also rise. At the equity level, miners with copper production growth, improving cash flow, and room for valuation rerating are more favored, while companies with greater cost exposure, iron ore freight exposure, weak diamonds, or higher project execution uncertainty face relatively more pressure.

Risks

• The outcome of U.S. Section 232 tariffs is uncertain; if the path differs from market expectations, it could change inventory migration and price direction.
• Higher tariffs may continue to drive U.S. inventory build, but could also later trigger destocking and price volatility.
• Copper prices are already at high levels, around $13,600/mt and up significantly year-on-year, leaving limited valuation and price margin of safety.
• The global refined copper market may be in surplus by more than 500kmt in 2025, meaning high prices need more policy and inventory logic support.
• A copper/aluminum price ratio above 4x typically signals substitution risk.
• Anglo American faces risks related to iron ore freight in Brazil and South Africa, weak diamonds, and 2Q production results.
• If the Collahuasi desalination plant shutdown persists, it may affect copper recoveries for Anglo American and Glencore in H2'26 or 2027.

What to watch

• Whether U.S. Section 232 refined copper cathode import tariffs proceed along a phased path from 15% to 30%.
• Whether U.S. LME and COMEX inventories continue to rise, or shift to destocking after policy certainty is established.
• Whether available non-U.S. inventories and LME cancelled warrants tighten further.
• Whether Chinese cathode copper premiums and inventories in SHFE and bonded warehouses continue to destock.
• Follow-up monthly data on China's refined copper demand, imports, and refined production.
• Growth in global mined copper output, especially data related to Chile, Peru, and Escondida.
• Anglo American's 2Q 2026 production results on July 23, 2026 and related cost risks.
• Updates on the Collahuasi desalination plant shutdown and its impact on recoveries in H2'26 or 2027.
