Copper cathode bundles in a warehouse, where available inventory has become central to price formation.
By Penny Langford
Copper has entered a new phase of market stress, with London Metal Exchange (LME) cash prices moving above US$14,850 per tonne as traders compete for nearby metal. The move is being driven less by a single demand shock than by a combination of falling LME stocks, tariff-related trade distortions and short-term delivery pressure.
The rally has also widened the gap between current prices and many published forecasts. TD Securities expects copper to remain elevated but ease later in the year, while ING sees tight ex-US inventories supporting prices but expects momentum to moderate. Commerzbank is more constructive on supply risk, warning that early surplus conditions may give way to a deficit as mine disruptions persist.
The result is an unusually wide range of outcomes for the copper price forecast 2026: a market that could retreat toward the low US$11,000s if inventories rebuild and tariff concerns fade, but could also retest or exceed US$15,000/t if the physical squeeze intensifies.
Copper market snapshot
The following table brings together the latest available LME reference figures and provides a linkable data point for tracking the market’s front-end conditions.
| Indicator | Latest reference | What it signals |
|---|---|---|
| LME cash copper | US$14,850/t | Exceptional prompt-market strength |
| LME 3-month copper | US$14,315/t | Lower deferred pricing |
| Cash–3M spread | +US$535/t | Deep backwardation and nearby scarcity |
| LME warehouse stocks | About 207,800 t | Low and volatile visible inventory |
| 2026 YTD performance | About +18% | Strong gains, although estimates vary by contract and reference date |

A cash price above the three-month contract means buyers are paying a substantial premium for immediate delivery. In a normally supplied market, storage and financing costs tend to push deferred prices above cash. Backwardation reverses that relationship: prompt material is more valuable because consumers, traders or short-position holders need it now.
That distinction matters. A high outright price can reflect macroeconomic optimism or speculative positioning. A large cash premium, combined with falling exchange stocks, provides stronger evidence of immediate physical tightness.
Visible copper inventory is increasingly concentrated in selected regions and warehouse systems.
How the squeeze developed
LME copper inventories have moved sharply in both directions during 2026. Stocks roughly halved over a period of about three months to below 205,000 tonnes before recovering to more than 233,000 tonnes. The later recovery did not remove the underlying concern: exchange stocks remained well below the levels reached earlier in the year, and available metal was unevenly distributed.
The inventory movement reflects a market divided between the United States and the rest of the world. Traders have directed copper toward US ports and COMEX warehouses in anticipation of possible tariffs on refined copper. That flow has increased US availability while reducing the pool of metal immediately accessible to buyers in Europe and Asia.
ING describes this as a tariff-driven distortion in the COMEX-LME arbitrage. Its analysis notes that COMEX inventories have risen sharply while inventories outside the US remain comparatively low. If the US imposes a tariff, metal already positioned in the country may command a premium. If the tariff is rejected or delayed, some of that material could flow back into the global market.
That is why the pending US decision has become a central variable in the copper outlook. The Commerce Department was expected to recommend a position on refined copper tariffs, but the White House has not yet delivered a final decision. Until that uncertainty clears, traders have an incentive to hold metal close to the US market, even if the eventual policy outcome changes the economics of those flows.
Backwardation is the market’s most important signal
The US$535/t cash-to-three-month spread in the market snapshot is more than a pricing anomaly. It indicates that the market is placing a high value on control of deliverable copper today.
Backwardation can be sustained by several mechanisms:
- Consumers rebuilding depleted inventories.
- Traders moving metal into the US ahead of a tariff decision.
- Short sellers seeking prompt material to meet delivery obligations.
- Mine disruptions reducing expected concentrate and refined output.
- A high share of warehouse stocks being cancelled and therefore unavailable for immediate delivery.
The signal is not infallible. Backwardation can be amplified by positioning around contract settlements and may narrow quickly when warehouse inflows resume. However, a sharp backwardation accompanied by low LME stocks is a stronger indicator of physical stress than price momentum alone.
The market structure also explains why copper prices can remain high even if some analysts expect supply to improve later. A deficit market needs above-ground inventories to satisfy both fabrication demand and precautionary stockpiling. If those inventories are tied up in the wrong region, the market can experience a shortage of prompt metal without an equally large global production deficit.
Structural demand remains strong, but not unlimited
The long-term demand case is anchored in power infrastructure. Grid upgrades require copper-intensive transmission and distribution equipment, including cables, transformers and substations. Renewable power adds demand for both generation equipment and the networks needed to connect new capacity.
Data centres and artificial-intelligence infrastructure are adding another source of electricity-related copper demand. High-density computing requires substantial power delivery, cooling and backup systems. The volume is smaller than China’s broader industrial consumption, but data-centre projects can create concentrated regional demand for electrical equipment and cabling.
The same is true of electric vehicles, charging networks and battery storage. These uses support copper consumption even when construction and traditional manufacturing are weak.
But high prices create offsets. Goldman Sachs expects grid and power infrastructure to account for more than 60% of copper-demand growth through 2030, while also warning that aluminium substitution could limit demand in selected industrial and consumer applications. Manufacturers may redesign components, reduce copper intensity or delay projects when prices become too high.
ING has likewise described demand as mixed. Non-property demand in China, including grid investment and electrification, remains supportive, while weak property activity and a lower Yangshan premium indicate that consumers are becoming more price-sensitive.
The key question is therefore not whether structural demand exists. It is whether that demand arrives quickly enough to absorb new mine supply, rising scrap flows and any metal released from US warehouses.
For broader context, Skillings’ analysis of the copper supply deficit, grid upgrades and AI data-centre demand examines the longer-term supply gap facing the sector.
Grid and power infrastructure are becoming increasingly important sources of incremental copper demand.
What TD Securities, ING and Commerzbank are saying
TD Securities has raised its 2026 copper forecast to an average of approximately US$13,000/t, with potential trading highs close to US$15,000/t. Its analysis identifies inventory hoarding, tariff fears and a growing supply-demand deficit as drivers of acute front-end tightness.
However, TD also expects that tightness to moderate later in the year. The return of disrupted production, new supply from ramping operations and slower inventory accumulation could reduce the premium embedded in prompt copper. Under that view, a retreat from record prices would represent normalization rather than a collapse in the structural demand story.
ING takes a more cautious central view. It forecasts an average price of about US$11,500/t, with prices peaking near US$12,000/t before losing momentum as tariff policy becomes clearer. Its refined copper balance shows a deficit of around 600,000 tonnes in 2026, but ING argues that US stock builds and the potential reversal of trade flows could ease the market later.
Commerzbank’s analysis highlights the opposite risk. The bank points to a first-quarter refined copper surplus of nearly 400,000 tonnes, caused by strong production and demand growth of less than 1%. It expects that balance to tighten as demand improves and production growth slows, with copper moving toward US$14,000/t by year-end.
Commerzbank’s supply concerns include weak Chilean output, operational issues at major mines and the risk that expected global mine growth will not be delivered on schedule. The bank’s view is that the early surplus may prove temporary if mine disruptions continue and smelter margins remain under pressure.
Copper price scenarios for 2026
Base case: US$11,500–US$13,500/t
The base case assumes that the current squeeze eases but does not disappear.
Some metal returns to the LME system, US tariff uncertainty becomes less disruptive and mine operations recover part of their lost output. Grid investment, renewable construction and data-centre development remain supportive, but Chinese property weakness and high prices limit demand growth.
Under this scenario, prices remain historically high and volatile. The annual average sits below the current cash price because the market gradually loses some of its prompt premium.
Bull case: US$14,000–US$15,500/t
The bull case requires several conditions to occur together:
- LME stocks fall back toward or below 200,000 tonnes.
- Backwardation remains wide for an extended period.
- Major mine disruptions persist in Chile, Indonesia, Peru, Zambia or the DRC.
- US refined-copper tariffs are introduced or remain a credible near-term threat.
- Grid, renewable and data-centre demand exceeds current expectations.
In this scenario, a print above US$14,850/t would not be an isolated event. It would reflect a market in which regional availability, delivery obligations and policy-driven stockpiling reinforce one another.
Bear case: US$9,500–US$11,500/t
The bear case assumes that the supply response arrives faster than expected.
Successful mine ramps, recovering disrupted operations and stronger scrap collection add metal to the market. The US tariff decision removes the incentive to move additional copper into COMEX warehouses, allowing some existing stocks to flow back toward Europe and Asia.
At the same time, high prices weaken Chinese consumption, manufacturers substitute aluminium where possible and data-centre or grid projects face permitting, financing or equipment delays.
Prices could then move toward the range identified by Goldman Sachs, which expects LME copper to remain broadly between US$10,000 and US$11,000/t in 2026 and forecasts a first-half average of US$10,710/t.
What operators and investors should monitor
The most useful tests of the forecast are physical rather than headline-driven:
- LME and non-US inventories: Continued draws would support the squeeze case.
- Cash-to-three-month spreads: Persistent backwardation would indicate ongoing prompt scarcity.
- Treatment and refining charges: Record-low fees would point to concentrate shortages and smelter pressure.
- Mine guidance: Revisions from major producers could quickly alter the projected balance.
- Chinese demand indicators: Imports, refined consumption and the Yangshan premium remain important.
- US tariff policy: A final decision could either reinforce the two-pool market or trigger a rapid flow reversal.
- Scrap availability: Higher prices can bring secondary copper into the market faster than new mines can respond.
The most defensible copper price forecast 2026 is therefore a wide range rather than a single target. The current squeeze can push cash prices above US$14,850/t, but TD Securities and ING both expect some easing as trade distortions and supply disruptions normalize. Commerzbank’s caution on mine supply provides the main upside risk.
For the mining sector, the critical issue is whether the market’s structural demand growth reaches the physical system before inventories and processing capacity become binding constraints. Until that question is answered, copper prices are likely to remain elevated: and unusually sensitive to warehouse movements, tariff headlines and mine-level disruptions.
