BlackRock Calls It a Supercycle – Mines and Vaults Agree

BlackRock’s Evy Hambro described the current market dynamics as a new commodity supercycle in an interview on Bloomberg. At the same time, spot gold traded near $4,177 an ounce and silver hovered around $60.87, largely unchanged on the day. Those static headline prices obscure a broader tightening across the metals complex. A key labor contract at the world’s largest copper mine reached its deadline, COMEX platinum holdings fell to a nine‑month low, copper’s futures curve began to price a near‑term shortage, and China is heading into Golden Week with gold import levels last seen in 2017. Together, these signals suggest supply is tightening even if spot prices have not yet accelerated.

Why Did BlackRock’s Evy Hambro Call This a New Commodity Supercycle?

Evy Hambro, BlackRock’s global head of thematic and sector investing, pointed to three structural forces converging: growing power demand for data centers supporting artificial intelligence, an accelerated electrification of transport and infrastructure, and a prolonged period of underinvestment in new mine capacity. Together, these forces reshape the supply curve for many industrial and precious metals.

That framing matters because a supercycle is about supply dynamics rather than a short‑term price forecast. Bringing a new mine online typically takes seven to fifteen years, while demand compounds year after year. If supply cannot keep pace, prices can remain tight for an extended period without any single dramatic catalyst. The recent operational and inventory signals across copper, platinum, and gold illustrate how the supply side is already under pressure.

What Happens Today at BHP’s Escondida Copper Mine?

BHP’s Escondida mine in Chile is the world’s largest copper producer. A supervisors’ union of roughly 1,000 members faced a labor contract expiration on September 30. Union leaders unanimously rejected the company’s final wage offer and urged members to vote in a strike referendum held over a three‑day window that also closed on that date. Under Chilean law, a formal strike cannot begin immediately: five days of mandatory government mediation are required, with a possible five‑day extension if both sides agree to continue negotiations.

Escondida’s production has already slipped. BHP’s August results showed the mine produced about 3% less copper in the most recent fiscal year compared with the prior year, and current guidance points to a further decline. A labor deadline at a mine that is already trending lower increases the risk of disrupted output during a period when global copper supply is tight.

Why Did COMEX Platinum Inventory Just Hit a Nine-Month Low?

Registered platinum on COMEX — the metal certified and available for delivery in approved vaults — fell to about 179,000 ounces as of September 24, the lowest level in nine months. That drawdown occurred unusually quickly compared with many prior inventory declines.

Platinum often flies below the radar of mainstream headlines, but the market mechanics mirror those of gold and silver. When registered, deliverable stock shrinks, the amount of metal actually available for immediate delivery falls even if broader “eligible” inventories remain stable on paper. That divergence between paper supply and deliverable supply is where price pressure and volatility tend to appear first.

What Does Copper’s Vault Split Say About the Futures Curve?

Trade flows influenced by tariffs and logistics have reshaped where copper inventories sit. Approximately 69% of copper held in global exchange warehouses now resides in COMEX facilities, leaving London Metal Exchange stock comparatively thin. That imbalance shows up in market structure: the spread between LME cash prices and three‑month contracts has widened into its steepest backwardation since 2021.

Backwardation — when near‑term metal commands a premium over later delivery — signals immediate scarcity rather than expectations of future shortage. It is a structural sign that metal is harder to access right now, and it often precedes price moves once physical shortages become more acute.

Why Are China’s Gold Imports Already Running at a 2017 Pace?

China’s Golden Week, the National Day holiday from October 1–7, traditionally marks the start of the country’s peak seasonal gold buying. Jewelry purchases rise, trade restocking accelerates, and local premiums firm. This year’s holiday arrives while imports are already elevated: customs data through August indicate gold imports have topped 1,000 tonnes, valued at roughly $158.8 billion — a pace that surpasses all of 2025 and sits more than 70% ahead of last year.

That kind of buying is structural and calendar‑driven rather than tactical. Chinese household and institutional demand tends not to chase short‑term headlines; it follows cultural seasons and inventory cycles. High import volumes ahead of Golden Week are the demand‑side counterpart to the supply constraints seen in copper and platinum.

None of these developments requires speculative forecasts to be meaningful. Instead of a new prediction, watch three near‑term dates that will clarify whether current signals intensify: Escondida’s union vote and the transition into formal mediation (which can last five to ten days), the next COMEX inventory report that will show whether platinum draws continue, and the end of China’s Golden Week on October 7, after which fresh import data will update the picture. Any one of these moves could confirm that the metals complex is already tighter than headline prices suggest.
