Copper holds near record highs as shrinking London stocks trigger battle for physical metal
Copper prices remain close to historic levels as inventories registered with the London Metal Exchange fall sharply and buyers pay increasingly large premiums for immediate delivery. The squeeze highlights growing concerns over global supply at a time when the US, China, electrification and AI infrastructure are competing for the same strategic metal.
Copper is sending an increasingly powerful signal to global commodity markets. The issue is no longer simply how high the metal’s headline price can climb, but how much buyers are willing to pay to secure copper right now.
Prices remain close to record territory as tightening availability in the London market pushes premiums for immediately deliverable metal to levels not seen since the severe copper squeeze of 2021. The movement is raising the prospect of an intensifying battle for physical stocks held in warehouses linked to the London Metal Exchange (LME).
The market structure is particularly revealing. August copper traded at a premium of around $370 per tonne over September, according to market data reported by MINING.COM, marking the widest one-month spread since the disruption that forced the LME to take emergency measures five years ago.
This phenomenon, known as backwardation, occurs when copper available for immediate delivery becomes more expensive than metal promised for a later date.
In normal conditions, future delivery often commands a higher price because of storage, financing and other costs. When that relationship reverses sharply, it can indicate that buyers value physical availability more highly than future supply.
And that is precisely what is making the latest copper rally different.
Copper’s record price is only part of the story
The copper market has already experienced an extraordinary year.
London prices have climbed far beyond the levels considered exceptional only a few years ago, while US copper futures have also reached records. In early August, London copper moved above $14,000 per tonne, while September Comex futures subsequently touched $6.7140 per pound — equivalent to around $14,800 per tonne.
But prices alone do not fully explain the pressure.
The more important indicator may be the rapid deterioration in readily available LME inventories.
Stocks in LME warehouses fell to approximately 214,550 tonnes, declining by more than 35,000 tonnes — around 14% — since the end of July.
At the same time, traders willing to surrender physical copper are demanding increasingly large premiums.
That combination — high outright prices, falling exchange stocks and steep backwardation — suggests the market is becoming particularly sensitive to any disruption in the physical supply chain.
The world has copper — but much of it is in the wrong place
One of the paradoxes of the current market is that copper has not simply disappeared.
Large quantities of metal have accumulated in the United States after months of trade flows distorted by expectations surrounding US tariffs.
Around 200,000 tonnes arrived in the US during July alone, the largest monthly inflow in shipping data going back to 2014.
The result has been a geographic imbalance.
Copper inventories have been pulled toward the United States while available stocks elsewhere have tightened.
The process illustrates an important characteristic of commodity markets: global inventory figures can look relatively comfortable while regional availability becomes extremely constrained.
For a manufacturer in Europe or Asia, copper stored thousands of kilometres away in an American warehouse is not necessarily equivalent to metal immediately available through the LME system.
The copper market is therefore confronting not only a question of how much metal exists, but where that metal is located.
A bidding war could emerge around LME warehouses
The tightening market creates increasingly powerful incentives for owners of physical copper.
Warehouses, traders, consumers and other market participants can compete to attract available metal.
When immediate delivery commands a substantial premium, every tonne sitting outside the exchange system becomes more valuable.
This raises the prospect of a bidding battle around copper that could potentially be delivered into LME warehouses.
The significance extends beyond commodity traders.
The LME is one of the central reference points for global industrial-metal pricing. Severe shortages of immediately deliverable inventory can amplify volatility across contracts used by miners, manufacturers, traders and financial institutions to hedge their exposure.
The market experienced an extreme example in October 2021, when copper spreads surged dramatically and the LME introduced measures intended to restore orderly trading.
The return of spreads to their widest levels since that episode is therefore attracting considerable attention.
The US copper magnet changed global trade flows
The current squeeze cannot be understood without looking across the Atlantic.
Expectations surrounding American trade policy have repeatedly transformed the copper market.
The prospect of tariffs created an incentive to ship refined metal into the United States before potential restrictions took effect. That arbitrage helped redirect large quantities of copper away from other trading centres and into American warehouses.
This phenomenon has already demonstrated how quickly policy decisions can reorganise physical commodity flows.
Antofagasta, one of the world’s major copper producers, noted in its 2025 annual report that tariff expectations had generated a substantial premium between Comex and LME prices, drawing copper into the US while inventories in markets including London and Shanghai declined.
The consequences are still reverberating through the market.
Even when total global stocks appear sufficient, the concentration of metal in one country can leave other regions competing for fewer immediately available tonnes.
Supply disruptions add another layer of pressure
Geography is only part of the problem.
The copper industry is simultaneously confronting production disruptions and policy changes in several important producing countries.
The Democratic Republic of Congo, one of the world’s largest copper producers, recently imposed restrictions on exports of copper and cobalt concentrates as it seeks to encourage greater domestic processing.
Analysts do not necessarily expect the measure by itself to remove enormous quantities of refined copper from world markets, but its timing matters.
It arrived when the raw-material market was already tight and LME inventories were declining.
Elsewhere, Chile has reduced its production expectations, while operational problems have affected processing capacity connected with Indonesia’s giant Grasberg copper complex.
These events reinforce a central weakness in the copper market: supply cannot respond quickly when demand or trade flows suddenly change.
New copper mines take years to arrive
Unlike many manufactured products, additional copper supply cannot simply be switched on when prices rise.
Large mining projects can require years — and sometimes decades — of exploration, permitting, financing, construction and infrastructure development before producing their first tonne.
Existing deposits are also becoming more complex in many jurisdictions, while lower ore grades mean miners may need to process greater quantities of rock to produce the same amount of copper.
Antofagasta expects supply growth to continue lagging demand growth over the medium term and warns that permitting constraints, disruptions and geopolitical uncertainty could maintain significant volatility.
That slow supply response is becoming increasingly important because copper demand is expanding into sectors far beyond its traditional industrial uses.
AI is becoming part of the copper story
Copper has always been essential for construction, manufacturing and electrical systems.
But the energy transition and digital economy are adding new sources of structural demand.
Electric vehicles require considerably more copper than conventional combustion-engine vehicles. Renewable-energy installations need extensive wiring. Modern electricity grids require enormous quantities of conductive material.
And now artificial intelligence is adding another layer.
Data centres require electricity infrastructure, transformers, cooling systems, backup power and extensive cabling. The rapid expansion of AI computing therefore translates into additional demand not only for semiconductors but also for the physical metals required to build and connect the infrastructure.
This is changing the market’s perception of copper.
The metal is increasingly viewed not merely as a cyclical proxy for construction and industrial production, but as a strategic resource for electrification, energy security and digital infrastructure.
China remains crucial — even as demand signals are mixed
No analysis of copper can ignore China.
The country remains the world’s dominant consumer and processor of the metal, meaning changes in Chinese industrial activity can rapidly affect global pricing.
Yet the current rally is unusual because it does not appear to be driven solely by booming conventional Chinese demand.
Supply constraints, shrinking inventories, trade distortions and competition for physical metal are playing an unusually important role.
That distinction matters.
Historically, copper’s reputation as “Dr. Copper” came from its perceived ability to diagnose the health of the global economy: strong copper prices often implied robust construction and industrial demand.
In 2026, record or near-record prices may be telling a different story.
They may reflect scarcity and strategic competition for supply as much as global economic strength.
Europe has particular reason to watch the squeeze
For Europe, expensive copper represents more than a financial-market story.
The EU is simultaneously attempting to expand renewable energy, electricity networks, electric mobility, defence capabilities and data-centre infrastructure.
All of those sectors require copper.
Europe is also highly dependent on international supply chains for many critical raw materials, making extreme price movements and regional inventory shortages strategically relevant.
A sustained copper squeeze could increase costs for European manufacturers precisely when the continent is trying to accelerate investment in electrification and strengthen industrial competitiveness.
Copper prices therefore sit at the intersection of several of Europe’s biggest economic challenges: energy transition, industrial policy, digitalisation and access to strategic raw materials.
High prices could eventually destroy demand
The bullish picture is not without risks. Copper trading close to historic highs can eventually produce its own counterweight.
Manufacturers may reduce inventories, delay investment or redesign products to use less copper. In some applications, aluminium can substitute for copper. Slower economic activity could also reduce construction and industrial consumption.
High prices can additionally encourage recycling and make previously marginal mining projects economically viable.
And large quantities of copper remain stored in the United States.
If trade incentives change and that metal begins flowing back toward Europe or Asia, the current regional shortage could ease quickly.
This is why the steep backwardation is important but should not automatically be interpreted as evidence of a permanent global deficit.
It primarily signals an acute shortage of the right copper, in the right place, at the right time.
Copper becomes a geopolitical metal
What is happening in London illustrates a much larger transformation.
For decades, copper was treated primarily as an industrial commodity. Today it increasingly resembles a strategic asset.
The United States wants secure domestic supplies. China dominates significant parts of the refining and manufacturing chain. Producing countries are seeking to capture more value domestically. Europe needs huge quantities for its energy and digital transitions.
Meanwhile, AI, electric vehicles, renewable energy and grid expansion are creating new structural demand.
The result is a market where tariffs in Washington, export policy in Congo, mine disruptions in Chile or Indonesia and warehouse stocks in London can interact almost immediately.
The price near record highs is the visible consequence.
The more important story is happening underneath.
Copper buyers are increasingly competing not simply over price, but over physical access to one of the metals that will underpin the global economy’s next phase of electrification and digitalisation.
