The copper price fell to a three-week low on Monday as traders unwound positions ahead of a critical September 30 deadline on US refined-copper tariffs. At the same time, a reassessment of Federal Reserve policy added fresh pressure to dollar-denominated metals. The move ended copper’s impressive 10-week winning streak and brought the London Metal Exchange (LME) three-month price down sharply from its record highs reached earlier this month.
Here is a full breakdown of what drove the copper price lower, what traders are watching next, and what the long-term outlook looks like given ongoing supply constraints and rising structural demand.
Copper Price Today: Market Snapshot
The copper price today on the LME sits near $14,000–$14,002 per tonne — a sharp retreat from the all-time record of $14,854/t set on September 9, 2026. That peak came at the height of tariff-driven stockpiling activity, as US buyers rushed to accumulate refined copper ahead of a potential import duty.
| Indicator | Latest Signal | Market Significance |
|---|---|---|
| LME 3-month copper price | ~$14,000–14,002/t | Down from the Sept. 9 record high |
| LME record high (Sept. 9) | $14,854/t | Peak reached during tariff-driven rally |
| LME cash settlement (Sept. 11) | $14,238.50/t | Nearby physical metal still at premium |
| LME warehouse stocks | 234,475 tonnes | Well below US stockpile levels |
| US (COMEX) copper inventories | ~675,000–700,000 tonnes | Could weigh on global prices if released |
| Potential US refined-copper tariff | 15%–30% | Rate and timing still undecided |
| Section 232 policy deadline | September 30, 2026 | The single biggest near-term catalyst |
Why Did the Copper Price Drop?
Two forces are pulling the copper price lower right now: tariff uncertainty and Federal Reserve risk. Neither is a new story, but the market’s interpretation of both has shifted over the past week.
Tariff Premium Unwinding
For weeks, traders treated a US refined-copper tariff as near-certain. That expectation drove a flood of metal into American warehouses. COMEX-approved stocks rose for 57 consecutive trading days, reaching roughly 696,259 metric tonnes. The front-month COMEX-LME spread — which had opened wide as US buyers competed for imported metal — has since turned negative at times, making further shipments to the United States unprofitable.
When that spread flips negative, the incentive to move copper into the US vanishes. Traders who positioned for a continued premium are now unwinding, and that repositioning is pushing the copper price down across both LME and COMEX contracts.
Federal Reserve Uncertainty
A firmer US dollar and growing expectations that the Federal Reserve may hold interest rates higher for longer have added a second layer of pressure. A stronger dollar makes copper more expensive for buyers in other currencies and pushes investors to reduce exposure to cyclical commodities like base metals. The dual headwind of tariff uncertainty plus Fed risk is a difficult combination for any industrial metal to absorb in the short term.
US Copper Tariffs: What Could Happen on September 30?
The White House has not yet imposed tariffs on refined copper under the Section 232 national security review process. Market discussions have focused on potential duties of 15% to 30%, but no rate has been confirmed. The September 30 deadline is now the single most important near-term catalyst for the copper price.
If a Tariff Is Imposed
A tariff of 15% to 30% on refined copper would encourage US buyers to hold existing inventories and continue competing for imported metal before the duty takes effect. That would tighten supplies for European and Asian consumers and likely revive the COMEX-LME premium. It would also improve the long-term investment case for domestic US mines, smelters, and refineries — but new production capacity takes years to build, so no immediate supply relief would follow.
Higher input costs would also ripple through to wire manufacturers, construction companies, EV makers, data-center developers, and power-grid contractors — all of which are heavy copper consumers.
If the Tariff Is Rejected or Delayed
If Washington passes on a tariff or pushes the decision further out, the US premium could narrow significantly. Some of the roughly 675,000–700,000 tonnes sitting in American warehouses could gradually re-enter international trade, putting downward pressure on global copper prices. That said, it would not resolve the underlying concentrate shortage at the upstream end of the supply chain.
Analysts at Capital.com note that the US tariff framework finalized in late June 2026 temporarily exempted refined copper imports while scheduling phased tariffs from 2027 — suggesting a delayed but not eliminated tariff risk remains on the table regardless of the September 30 outcome.
Physical Copper Market Remains Tighter Than the Headline Price Suggests
One important nuance: the futures price decline does not tell the whole story. The copper price in cash markets has stayed relatively firm compared with the drop in three-month futures contracts. That divergence shows that buyers still pay a premium for metal available immediately, even as speculative and forward positions are repriced lower.
This split reflects two very different dynamics within the copper supply chain:
Upstream (concentrate): Copper concentrate remains hard to secure globally. Treatment and refining charges — what smelters earn for processing raw ore into refined metal — have fallen close to zero in parts of the market. Near-zero treatment charges signal that miners have the upper hand, because there simply is not enough concentrate available for smelters to run at full capacity.
Downstream (refined metal): The United States has built up a large stockpile of refined copper, but this metal is geographically trapped by economics and trade policy. LME warehouse stocks remain comparatively low at around 234,000 tonnes — well below the US accumulation — which means the global physical market is tighter than headline US inventory numbers imply.
Federal Reserve and the Dollar: How They Affect the Copper Price
The copper price does not move in isolation. As a dollar-denominated commodity traded globally, copper responds strongly to shifts in US monetary policy and the direction of the dollar.
When the dollar strengthens, copper becomes more expensive for buyers using euros, yuan, or other currencies. That tends to reduce demand and push prices down. When the Fed signals rate hikes — or keeps rates elevated longer than expected — investors also pull money out of cyclical commodities like copper and into safer, higher-yielding assets.
US economic data therefore carry double weight: strong activity data can support copper demand from construction and manufacturing, but it can also harden the case for Fed tightening. Weaker data can ease monetary pressure but also raises fears about end-user demand. Right now, copper is navigating both of these tensions simultaneously.
Copper Price Forecast 2026: What Analysts Are Saying
Despite the recent pullback, the longer-term structural case for the copper price remains intact. The transition to clean energy, electrification of transport, and the global build-out of power grids all require enormous quantities of copper.
Here is where major analysts currently stand on the copper price forecast for 2026:
| Institution | 2026 Price Forecast | Key Assumptions |
|---|---|---|
| Bernstein | $12,419/t avg; $11,750/t in H2 | Tariff dynamics, Hormuz risk premium removal |
| Macquarie | $13,165/t avg (raised from $12,310) | Evolving tariff dynamics, supply constraints |
| Goldman Sachs | $11,400/t avg (raised from $10,650) | 55% probability of 15% US tariff; structural demand growth |
| Goldman Sachs (long-term) | $15,000/t by 2035 | Grid and power infrastructure driving 60%+ of demand growth |
| J.P. Morgan | 330,000-tonne deficit in 2026 | Supply shortfall supporting price floor |
The International Copper Study Group (ICSG) has revised its 2026 deficit forecast to 150,000 tonnes, providing a structural price floor even as the tariff premium unwinds.

Key Indicators to Watch for the Copper Price
These are the metrics that traders and analysts are tracking most closely right now:
- COMEX warehouse withdrawals — Rising withdrawals mean the US stockpile is being consumed domestically rather than released into global trade. That supports international prices.
- LME cash-to-three-month spread — Persistent backwardation (cash above futures) signals continuing nearby tightness and underpins the physical market.
- US copper premium vs. LME — A narrowing premium shows that tariff-related stockpiling is losing momentum and could lead to a broader copper price retreat.
- Treatment and refining charges (TC/RCs) — Charges near zero continue to signal that miners are winning the battle for smelter capacity, keeping concentrate tight.
- Chile and Peru mine output — Production disruptions in major copper-producing nations can quickly tighten the market when LME inventories are already low.
- US dollar index and Fed statements — A stronger dollar and hawkish Fed language remain headwinds. Watch for any pivot in language from policymakers.
- China manufacturing data — China consumes roughly half of the world’s copper. Any change in Chinese industrial activity has an outsized effect on global demand.
Frequently Asked Questions: Copper Price
As of mid-September 2026, the LME three-month copper price is trading near $14,000–$14,002 per tonne, down from its September 9 record high of $14,854/t. For live prices, check the Investing.com copper page or Kitco’s base metals tracker.
The copper price is falling because traders are reducing bets on a near-term US refined-copper tariff ahead of the September 30 policy deadline. The large buildup of copper in US warehouses — around 675,000–700,000 tonnes — has also reduced urgency around domestic supply. On top of that, expectations for a firmer Federal Reserve and a stronger dollar are weighing on all dollar-denominated industrial metals.
Analyst forecasts for the 2026 average copper price range from around $11,400/t (Goldman Sachs) to $13,165/t (Macquarie). The wide range reflects uncertainty over US tariff policy, Federal Reserve direction, and China’s copper demand. Goldman Sachs maintains a long-term target of $15,000/t by 2035, driven by grid infrastructure and electrification demand.
The US is reviewing whether to impose tariffs of 15%–30% on refined copper imports under a Section 232 national security process. A tariff would make imported copper more expensive in the US, support domestic copper premiums, and tighten supply for buyers in Europe and Asia. A rejection or delay would likely narrow the US price premium and could send some of the 675,000+ tonnes in US warehouses back into global trade, putting downward pressure on the copper price internationally.
Copper has strong long-term structural demand driven by EV adoption, renewable energy, power grids, and data-center construction. However, the near term (late 2026 through 2027) carries significant policy risk tied to US tariff decisions and Federal Reserve actions. Most analysts describe 2026 as a high-volatility year with sharp price moves in both directions.
