Nvidia no longer No. 1?

Cash copper settled at a record $14,822 a tonne on Monday and $14,741 on Tuesday. On Wednesday, three-month copper on the LME climbed as far as $14,700, its highest since September 23, before easing to $14,532. Behind those numbers is a detail that matters more than any single session’s close: LME inventories have fallen for seven straight sessions to 229,650 tonnes. That persistent drain is not noise. It is a signal about where the world’s physical metal is, and where it is not.

Visible stocks worldwide are up 300,000 tonnes this year, but that is the US build. Everywhere else they are down 168,000 tonnes, and Macquarie says sentiment will not turn until LME and Shanghai inventories start rising again, either quickly on a tariff decision or gradually as forecast surpluses feed through. The geographic split is the whole story. Copper has not disappeared; it has been rerouted.

The spread that built the US stockpile has all but disappeared on a spot basis. Comex October copper at $6.62 a pound trades below LME cash, which at Tuesday’s $14,741 works out to $6.69, and John Gross of The Copper Journal calculates the month-to-date average has flipped to an 85-point LME premium from a 17-cent Comex premium in June. The arb that sucked metal across the Atlantic is gone. The metal, however, has not come back.

What Copper Confirms About the Broader Metals Story

Gold is trading around $4,146 an ounce this morning and silver near $55.84. Both remain in long-term uptrends driven by real-rate uncertainty, dollar softness, and central bank buying. Copper at record cash levels adds a different layer to that picture.

When the industrial metal with the most direct read on global electricity demand and construction activity pushes to all-time cash highs, it typically means one of two things: genuine demand acceleration, or a supply distortion severe enough to mimic it. Right now, it is mostly the second. Prices “have disconnected from the fundamentals and could arguably move higher or lower depending on the outcome of the Section 232,” Macquarie’s strategists write in a quarterly compendium whose copper chapter is headed “The great copper gamble,” listing the metal among preferred commodities for the next six to nine months “but very binary.”

For gold and silver investors, that binary outcome matters. If tariff resolution floods LME warehouses with redirected US copper, a sharp price unwind in the industrial complex could drag silver with it. Silver’s dual identity as both a monetary and industrial metal means it carries that risk in a way gold does not. A copper collapse would likely widen the gold-silver ratio, at least temporarily. Conversely, if the tariff standoff continues and ex-US tightness deepens, silver’s industrial demand profile becomes a tailwind.

The Investment Case for Copper Equities

The miners have run hard. Copper producers fell with the metal on Wednesday, Freeport-McMoRan down 3.7% and Southern Copper 3.3%, but the year has been kind. Southern Copper is up 44.1% in 2026, taking its market value to $169 billion, with Glencore ahead 38.6%, BHP 38.0% and Freeport 37.4% at a $100 billion valuation.

The more important question is what the stocks are pricing. RBC Capital Markets calculates that North American copper producers at 1.0 times net asset value imply a copper price of $5.03 a pound, from $5.98 for Freeport down to $3.96 for Ivanhoe Mines, against a futures price near $6.70. That gap is the embedded optimism, and it cuts both ways. If the Section 232 decision locks copper above $6.50, the stocks look cheap on a cash-flow basis. Freeport generated $1.5 billion in operating cash flows in the first quarter of 2026, and its full-year operating cash flow is projected at approximately $8.7 billion based on $6.00 per pound copper. At $6.70, those numbers improve materially. At $5.00, the valuation re-rating runs in reverse.

Freeport’s cash-flow sensitivity to copper price is not the only variable the market is repricing. Freeport’s Grasberg gold output is the secondary lever analysts are leaning on when upgrading the stock at current copper prices.

Risks to Monitor

The tariff outcome is the dominant variable, and it is unresolved. The US Commerce Department was due to report on the domestic copper market by June 30 so the White House could decide whether to impose a 15% tariff on refined copper imports from January 1, 2027. Since then, the White House has directed Commerce to provide an update on domestic copper markets by June 30, 2026 to inform whether moving ahead with a phased refined-copper tariff would be warranted. No refined-copper tariff decision has been announced.

Supply disruptions in Chile add genuine tightness on top of the tariff-driven distortion. A mudslide following heavy rainfall at Chile’s El Teniente mine is fuelling concerns about further supply disruptions. Chinese inventories are thin, and importers are paying a premium of around $118 over the LME price, the highest since 2022.

The El Teniente mudslide is not the only Chilean supply risk in play. BHP’s Escondida, which alone accounts for roughly 5% of world supply, entered mandatory government mediation after supervisors voted 94.8% in favour of strike action.

Bottom Line

Record cash copper with falling LME inventories tells precious metals investors that industrial demand for hard assets remains intact, but that the architecture underneath the copper price is fragile in a specific way. The tightness is real where you cannot access US-held stockpiles, and artificial where you can. That distinction matters enormously for silver. Gold, insulated from the industrial demand channel, is less exposed to a copper unwind. For investors holding both, watch whether LME inventories stabilize in the coming sessions. A reversal there would be the first concrete sign that the Section 232 calculus has shifted, and that copper’s record cash premium is beginning to unwind.
