BlackRock Declares a Supercycle; Mines and Vaults Agree

BlackRock’s Evy Hambro described the current market as a potential new commodity supercycle on Bloomberg Wednesday. Spot gold traded near $4,177 per ounce and silver hovered around $60.87, with little movement for the day. Yet other indicators reveal a tighter metals market than headline prices imply. A pivotal labor contract at the world’s largest copper mine reached its expiration, COMEX platinum inventories dropped to a nine-month low, copper’s futures curve signaled tightening supply, and China’s Golden Week begins tomorrow amid gold import levels not seen since 2017. Together these signals suggest the metals complex faces structural constraints that could push prices higher over time—even if daily price action looks muted.

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

Evy Hambro, BlackRock’s global head of thematic and sector investing, argued that commodities are entering a new long-term cycle driven by three converging trends: rising power demand from AI data centers, accelerated electrification worldwide, and years of underinvestment in new mine capacity. His point emphasizes supply dynamics rather than predicting short-term price swings.

The crucial idea is the supply curve. Bringing a new mine online typically takes seven to fifteen years, while demand for key metals compounds annually. Under those conditions, even steady increases in demand can create persistent tightness without any single dramatic catalyst. Prices can remain pressured simply because production cannot respond quickly. The developments below are real-time signals consistent with that structural squeeze.

What Happens Today at BHP’s Escondida Copper Mine?

BHP’s Escondida mine in Chile is the world’s largest copper producer. On September 30 the supervisors’ union—roughly 1,000 members—saw their labor contract expire. Union leaders rejected BHP’s final wage offer and called for a strike vote during a three-day window that also closes on the same date. A no vote does not automatically trigger a strike: Chilean labor law requires five days of mandatory government mediation before any work stoppage, with the option for both sides to extend mediation by another five days if they agree.

Escondida already produced about 3% less copper in the most recent fiscal year compared with the prior year, according to BHP’s August results. Guidance for the current fiscal year points toward a further decline, potentially a significant one. That means a major copper source was already trending down when a labor deadline arrived, creating a realistic near-term supply risk. The coincidence of this timing with broader supply concerns underlines why analysts emphasize structural constraints over short-term price moves.

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

Registered platinum refers to metal certified and available for delivery in COMEX-approved vaults. As of September 24, registered platinum inventories fell to 179,000 ounces—the lowest level in nine months. The pace of that drawdown was unusually fast compared with most previous declines.

Platinum tends to draw less headline attention than gold or silver, but the market mechanics are the same. When registered, deliverable inventories thin, the amount of metal actually available for prompt delivery shrinks even if broader “eligible” stocks remain unchanged. Markets can appear well supplied on paper while the deliverable slice tightens, and that divergence often breeds price volatility first. Monitoring registered stock levels is a direct way to gauge deliverable supply pressure.

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

Tariff-driven flows have shifted the global copper inventory landscape over the past eighteen months. Approximately 69% of copper held in exchange warehouses is now in COMEX facilities, leaving the London Metal Exchange (LME) with a relatively thin stockpile. That imbalance shows up in the futures market: the gap between the LME cash price and its three-month contract has widened sharply, producing the most pronounced backwardation since 2021.

Backwardation occurs when near-term metal trades at a premium to later-dated contracts, signaling scarcity in the immediate market rather than expectations of future tightness. Unlike a rising spot price, backwardation reflects the relationship between contract months and is a direct market signal that metal is harder to obtain today. When traders describe copper as “tight,” this spread is often the clearest evidence.

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

China’s National Day holiday, Golden Week, runs October 1–7 and typically marks the start of the country’s peak seasonal gold-buying period. Jewelry purchases rise, trade restocking accelerates, and local premiums firm. This year Golden Week begins against an already-elevated import pace: China’s customs data show gold imports topping 1,000 tonnes through August, worth roughly $158.8 billion—surpassing all of 2025 and running more than 70% ahead of last year.

This scale of buying is structural and often price-insensitive: households and institutions in China buy according to seasonal and strategic factors rather than reacting to week-to-week headlines. That demand complements the supply-side constraints outlined earlier. While Western strategists can debate the existence or timing of a supercycle, Chinese demand growth is a real, measurable factor tightening global physical markets.

Rather than rely on another forecast, watch three near-term dates for confirmation: Escondida’s talks are expected to enter formal mediation if the union vote follows leadership guidance; COMEX’s next inventory report will update the platinum picture; and October 7—when Golden Week ends—will bring fresh Chinese import data. Movements on any of these dates will likely send clearer signals about supply and demand than another speculative headline.
