Why Copper Held Above $14,000: Supply Squeeze, Tariff Fears, and a Dovish Fed

Copper climbed above $14,000 per metric ton on the London Metal Exchange and held that level through six consecutive weekly gains — a run that reflected a rare alignment of supply squeezes, policy shocks, and macro tailwinds.

Collapsing LME Inventories

The single biggest driver was the dramatic drawdown in LME-registered copper stocks. Inventories fell from a May 2026 peak of just over 400,000 tons to 223,000 tons by August 7 — a 33% drop in 30 days, with metal draining for 29 consecutive trading sessions . Available on-warrant metal — copper immediately deliverable against LME contracts — fell to about 113,000 tons in late July, the lowest level in six months .

This physical scarcity pushed the LME cash-to-three-month contract into backwardation, meaning buyers paid a premium for immediate delivery — a classic sign of a tight market .

Record US Imports and Tariff Stockpiling

The inventory drain was accelerated by an enormous wave of copper shipments to the United States. US copper imports exceeded 200,000 metric tons in July 2026, the highest monthly volume in more than a decade, according to IHS Markit shipping data . Traders and industrial buyers pulled metal out of LME warehouses around the world and shipped it to the US ahead of a potential import tariff by the Trump administration .

COMEX stockpiles soared more than 300% year-to-date to over 400,000 tons — an all-time high — as the metal accumulated in US warehouses . The result: a bifurcated market where copper piled up in the US even as it disappeared from the rest of the world, tightening deliverable supply in the LME system .

Weaker US Rate Outlook

A key macroeconomic headwind suddenly reversed on August 7, when the US Bureau of Labor Statistics reported that nonfarm payrolls unexpectedly fell by 23,000 in July, against a consensus forecast of an 80,000 gain. May and June payrolls were also revised down by a combined 103,000 jobs .

That shocked markets. Expectations for a Federal Reserve rate hike at the September meeting collapsed, and traders priced in a higher probability of no move — or even a cut . The US dollar weakened, making dollar-denominated commodities like copper cheaper for non-US buyers and providing a broad lift to metals prices .

DRC Concentrate Export Ban

On August 6, reports emerged that the Democratic Republic of Congo had banned exports of copper and cobalt concentrates under a joint ministerial order signed June 29 . The ban, signed by the ministers of mines, foreign trade, and economy, prohibits the export of intermediate concentrates in a push to force domestic processing and capture more value from the country's mineral wealth . One-year waivers may be granted for strategic projects .

The immediate impact on refined copper supply is limited: the DRC already exports mostly refined copper cathode — 696,725 tons in Q1 2026 versus only 53,926 tons of concentrates . But the ban tightens feedstock for global custom smelters at a time when many are running at critically low margins, and it reinforces the broader narrative of supply scarcity . The news pushed LME copper to a six-month high of $14,369.50 per ton .

Demand-Side Crosscurrents

China — aggressive restocking, not strong end-use. Chinese copper imports hit a nine-month high in July, and SHFE copper inventories plunged more than 80% since mid-March to just 79,909 tons . But much of that buying appears to be pre-tariff front-loading and restocking, not a surge in organic industrial demand. China's property sector remains weak, and the sheer speed of stock-drawing signals anxiety about future availability rather than a boom in consumption.

Eurozone — a modest tailwind. The eurozone manufacturing PMI moved into expansion territory during the period, providing a positive demand signal for industrial metals including copper .

The Main Risk: Tariff Unwinding

Much of the recent price strength is driven by stockpiling flows — buyers pulling metal into the US and China ahead of potential tariffs. If tariff decisions are delayed, softened, or reversed, a wave of destocking could quickly unwind the price gains. The rally is supported by genuine physical scarcity in the LME system, but the tariff premium embedded in current prices creates downside vulnerability .

Broader Impact on Other Metals

• Gold and silver benefited from the same weaker Fed rate outlook and softer dollar. The July jobs report that boosted copper also pushed precious metals higher as the probability of rate hikes faded .
• Aluminum and zinc saw support from the broader LME inventory drawdown and the positive eurozone manufacturing signal. Aluminum inventories fell 1,500 tons on August 5 alone . But neither metal has copper's acute supply-disruption catalysts — aluminum faces ample global capacity, and zinc's mine-supply concerns are less severe.
• Palladium is more tied to auto-sector demand. It may see indirect support from the general metals rally and a weaker dollar, but it does not share copper's specific supply-tightening dynamics.

ING analysts noted that copper had surged above $14,000/ton on the LME "as tightening physical market conditions continued to support prices" . Goldman Sachs raised its end-2026 copper price target by more than 10% to $13,735/ton, and Citi forecast copper hitting $15,000 within the next year .

Bottom line: Copper's hold above $14,000 is fundamentally a physical-supply story — collapsing LME stocks, record US import pull, and the DRC ban — reinforced by a dovish Fed repricing. China's import surge supports the rally but adds tariff-driven front-loading risk. The broader metals complex is lifted by the weaker dollar, but copper is the standout due to its uniquely tight deliverable supply.
