Copper fell 4.4% from its record high after reports the White House delayed a refined-copper tariff decision, easing the stockpiling rush that had driven the rally.
At a glance
- Comex copper fell about 4.4% to $6.59 a pound, a day after touching a record $6.89, following reports the White House has delayed its refined-copper tariff decision.
- The tariff delay is reportedly tied to affordability concerns ahead of November's midterm elections, with officials weighing the political cost of higher prices for manufacturers and consumers against the case for protecting domestic production.
- LME on-warrant warehouse stocks rose by more than 35,000 tons -- the largest addition since 2024 -- as copper that traders had been steering toward US stockpiles started landing in exchange warehouses instead.
- Commerce Secretary Howard Lutnick had been tasked with recommending whether to impose a tariff starting at 15% in 2027 and rising to 30% in 2028; that recommendation, originally due by June 30, has still not been made public.
What happened
Comex copper futures fell about 4.4% to $6.59 a pound after reports emerged that the Trump administration has delayed its decision on tariffs for refined copper imports, a day after the metal touched a record $6.89 a pound. The rally that pushed copper to that record had been driven largely by traders and industrial buyers rushing to build US inventories ahead of an expected tariff, creating one of the world's largest copper stockpiles on American soil. With the tariff decision now stalled -- the White House is reportedly weighing affordability concerns ahead of November's midterm elections against support for domestic production -- some of that urgency has drained out of the trade. London Metal Exchange on-warrant warehouse stocks jumped by more than 35,000 tons, the most added in a single stretch since 2024, as metal that had been earmarked for the US began flowing back into the broader exchange system instead.
The details
A 4.4% single-session drop in copper looks dramatic on a chart, but the mechanism behind it is almost mechanical once you separate the metal's fundamentals from the trade that had been driving its price. Copper's climb to a record $6.89 a pound was never purely a story about mines and demand -- it was substantially a story about traders and manufacturers racing to get refined copper into the United States before a tariff made that same copper more expensive to import later. Buy now, beat the tariff: that logic pulled forward months of import demand into a compressed window and built one of the largest copper stockpiles the US has ever held on its own soil.
That kind of front-loaded buying only holds up as long as the tariff threat stays credible and imminent. Once reports surfaced that the White House had shelved its decision -- weighing the political cost of higher consumer and manufacturer prices against the case for protecting US smelters and mines, with November's midterms squarely in view -- the incentive to keep rushing metal into American warehouses weakened overnight. Some of the copper that had been earmarked for US delivery started landing in London Metal Exchange warehouses instead, and more than 35,000 tons showed up on warrant in a single stretch, the fastest build the exchange has seen since 2024.
The timeline behind the stalled decision helps explain why traders had priced in so much confidence that a tariff was coming. Commerce Secretary Howard Lutnick was tasked with recommending whether to impose a tariff starting at 15% in 2027 and climbing to 30% by 2028, with that recommendation originally due by the end of June. Three and a half months past that deadline, nothing has been made public -- and a government weighing affordability optics ahead of a midterm election has a very different incentive than one purely optimizing for domestic industrial policy. Every week the decision slips is a week where the stockpiling trade built around it looks a little more like it got ahead of itself.
None of this changes copper's longer-run demand story -- global electrification, grid buildouts and data-center construction are all still consuming more of the metal than mine supply is adding. What it does change is how much of the *near-term* price was riding on a specific policy outcome rather than on those slower-moving fundamentals. When a trade built on political timing meets political delay, the price gives back exactly what the timing had added -- which is a fair description of what just happened to copper.
Why it matters
A price move this size, driven by a single delayed policy decision rather than a change in how much copper the world actually mines or consumes, is a reminder that a meaningful chunk of copper's 2026 rally has been positioning, not fundamentals. For Indian buyers and manufacturers who've watched copper hit repeated records this year, this pullback shows that prices tied to a specific tariff outcome can move just as sharply in reverse the moment that outcome gets pushed back -- worth remembering before assuming the recent highs are the new floor.
Our read
Outlook: bearish. The drop is a direct, confirmed reaction to a specific policy delay that had been the main driver of copper's rush to a record price, and LME warehouse data corroborates real metal flowing back into the exchange system -- though the underlying tariff threat remains unresolved rather than cancelled, leaving room for the move to reverse if the policy timeline changes again.
What to watch
- Any further news on the White House's refined-copper tariff decision, since it has been the single biggest driver of copper's price swings in both directions this year
- LME on-warrant warehouse stock levels for whether the 35,000-ton build continues or was a one-off unwind of stockpiling positions
- Comex versus LME price spreads as a gauge of how much of the US stockpiling premium has actually come out of the market

Detailed analysis
Timeline
- 2026-06-30: Commerce Secretary Howard Lutnick's recommendation on a refined-copper tariff was originally due, proposing rates starting at 15% in 2027 and rising to 30% in 2028.
- 2026-09-13: Comex copper touched a record $6.89 a pound as stockpiling ahead of an expected tariff decision continued.
- 2026-09-14: Comex copper fell about 4.4% to $6.59 a pound after reports the White House had delayed its tariff decision; LME on-warrant warehouse stocks rose by more than 35,000 tons.
Inventory Drivers
LME on-warrant warehouse stocks rose by more than 35,000 tons, the largest single-stretch addition since 2024, as copper previously destined for US stockpiles began landing in exchange warehouses once the tariff decision stalled.
Government Policies
Commerce Secretary Howard Lutnick was tasked with recommending a copper tariff starting at 15% in 2027 and rising to 30% in 2028, with a decision originally due by June 30, 2026; more than three months later, the White House has reportedly delayed acting on it over affordability concerns ahead of the November midterms.
Trade Tariffs
Traders and industrial buyers had rushed refined copper into the United States for months to beat an expected tariff, building one of the world's largest copper stockpiles on US soil; reports of the tariff decision being delayed reversed some of that urgency and pulled copper prices down 4.4% from their record.
What could lift prices
- The underlying tariff threat hasn't disappeared, only stalled -- if the White House eventually does act on Commerce Secretary Lutnick's recommendation, the same stockpiling dynamics that drove copper to its record could reassert themselves.
- Copper's longer-run demand drivers -- electrification, grid infrastructure and data-center buildouts -- are unaffected by this specific policy delay and continue to support the metal's multi-year trajectory.
What could weigh on prices
- A 4.4% single-session drop confirms a meaningful share of copper's rally to $6.89 was positioning ahead of a tariff decision, not demand growth -- and that kind of price support can evaporate as quickly as it built.
- LME warehouses absorbing more than 35,000 tons in a single stretch shows real supply reappearing in the market once the incentive to hoard it in the US weakened, undercutting the narrative of acute physical scarcity.
Country impact
| Country | Impact | Reason |
|---|---|---|
| United States | High | The delayed White House tariff decision directly caused this price move -- months of stockpiling built around an expected tariff are now partly unwinding as the policy timeline slips, with US midterm election politics cited as a factor in the delay. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Metal Trading | Negative | Traders who built positions around an imminent US tariff decision are now unwinding those bets, sending copper into exchange warehouses instead of US stockpiles and pulling prices down sharply from their record. |
| Manufacturing | Positive | A pullback in copper prices lowers input costs for manufacturers using copper wire, cable and components, and a delayed tariff removes the near-term risk of a further price spike from import duties. |
Who gains, who loses
- US copper-consuming manufacturers: A pullback in copper prices and a delayed tariff decision both ease near-term input costs for manufacturers who buy refined copper for wiring, cabling and industrial components.
- Traders holding long positions built on tariff timing: Positions built around an imminent US tariff decision are losing value as that timeline slips, with copper falling 4.4% from its record in the immediate aftermath of the delay reports.
Other ways this could play out
- If the White House ultimately confirms a copper tariff, even on a delayed timeline, the stockpiling rush could resume and push prices back toward their recent record as traders again race to beat the effective date.
- If the tariff plan is shelved entirely rather than merely delayed, copper could settle into a lower trading range built more on actual mine supply and industrial demand than on anticipatory positioning.
Price risks
- A sudden confirmation of the delayed tariff, even at a lower rate than originally proposed, could reignite the stockpiling rush and reverse this pullback quickly.
- Continued policy uncertainty could keep copper volatile in both directions as traders reposition around every new headline on the tariff's status.
Historical comparison
- Since 2024: The more than 35,000-ton addition to LME on-warrant warehouse stocks was the largest single-stretch build the exchange had recorded since 2024.
