NextFin News - Copper's rally has further to run, BlackRock says, and this time the upward trend is backed by something a chart alone cannot provide: a physical market that is tightening while prices climb. The world's largest asset manager sees the red metal's advance extending, a call that lands as LME copper trades near record territory, exchange warehouses drain at the fastest pace in months, and a growing roster of analysts forecast the global market will swing into deficit this year.
The stance from BlackRock's Evy Hambro, head of global thematic investments, puts the asset manager alongside industry bodies and banks that see supply growth failing to keep pace with demand from electrification, grid buildout, and the artificial-intelligence data-center boom. The convergence is what separates this rally from the false starts copper investors have endured over the past decade.
The Setup: Prices Near Records While Inventories Drain
The market backdrop is unusually constructive for the bull case. LME copper cash settled at $14,850 a metric ton on Aug. 17, 2026, with the three-month contract at $14,315, according to market data compiled by Westmetall. More telling than the price level is what is happening to stocks: monitored LME copper inventories stood at 207,825 tons, down from roughly 302,000 tons in mid-July. That is a draw of nearly a third in about a month.
Inventory draws matter because they are the closest thing the metals market has to a real-time truth meter. Futures prices can be pushed around by speculators and macro sentiment, but when warehouses empty while prices rise, the signal is that physical buyers are absorbing supply faster than it arrives. The last time copper printed at these levels, in December 2025, the metal touched a record near $11,771 a ton on the LME before pulling back. Current prices sit well above that prior peak, which reframes the question from "can copper hold these levels?" to "what would have to break for the trend to reverse?"
The price action has been relentless. Copper has climbed from the low $13,000s in early July to nearly $15,000 in roughly six weeks, a move of more than 10 percent that has left short sellers under pressure and forced reluctant industrial consumers to cover forward needs. That kind of momentum, when paired with falling inventories, is the signature of a market transitioning from balanced to tight.
BlackRock is not alone in seeing room to the upside. The International Copper Study Group, an intergovernmental body that tracks the market, has warned that the global refined copper balance will swing from a modest surplus in 2025 to a deficit of 150,000 tons in 2026. J.P. Morgan Global Research projects a deficit of roughly 160,000 tons in 2026 and forecasts prices averaging around $11,000 a ton for the year. Both forecasts rest on the same mechanism: demand keeps growing while mine and refinery output growth slows.
Why the Trend Can Continue: The Deficit Mechanism
The bull case for copper is not built on a single surprise. It is built on a convergence of three forces that reinforce one another, and that is what makes the call worth taking seriously rather than dismissing as another commodity-cycle story.
First, supply growth is decelerating precisely when it needs to accelerate. The International Copper Study Group now expects refined copper production to grow just 0.9 percent in 2026, down sharply from 3.4 percent in 2025. The drag starts at the mine: mine production growth is forecast at about 1.4 percent for 2025 and only 2.3 percent for 2026, constrained by the availability of copper concentrates, the mined ore that smelters need as feedstock. When concentrate supply tightens, smelters cannot run at full capacity no matter how strong demand is or how high prices climb. That bottleneck converts a modest demand uptick into a genuine physical shortfall, and it explains why the deficit forecasts from the ICSG and J.P. Morgan are likely conservative rather than aggressive.
Second, demand is structurally embedded rather than cyclical. The ICSG expects refined copper usage to rise about 2.1 percent in 2026, reaching roughly 28.7 million tons globally, with China consuming about 58 percent of refined copper. The composition of that demand has changed. A decade ago, copper tracked Chinese construction and global manufacturing purchasing indexes. Today, an increasing share comes from power grids, renewable generation, electric vehicles, and the transmission buildout required by AI data centers. Those uses do not disappear when a quarterly GDP print disappoints; they are policy-mandated and capital-committed, with multi-year permitting and construction timelines that lock in copper intensity long before the metal is poured.
Olivia Markham, co-manager of BlackRock's World Mining Trust, captured the shift in a recent interview:
The AI story is as much a power and metal story as it is a technology story.
The point is that every server rack and every mile of transmission line is a copper purchase order waiting to be executed, and those orders are less sensitive to the business cycle than the construction and appliance demand that used to drive the market.
Third, the supply chain carries geopolitical and input risks that can turn a projected deficit into a larger one. Goldman Sachs has flagged that disruption to shipping through the Strait of Hormuz, combined with China's decision to ban sulfuric acid exports from May, could put 200,000 tons of Chilean copper production at risk, equivalent to about 1 percent of global supply. Sulfuric acid is a critical input for copper leaching operations, and Chile sources roughly a third of its acid from China. A 1 percent supply shock in a market already swinging into deficit is not a rounding error; it is the difference between a manageable shortfall and a price spike that forces rationing among consumers.
Cyclical Rally or Structural Regime Shift?
This is the decision that determines whether the call is a trade or an investment thesis, and getting it wrong flips the conclusion. The evidence points to a structural regime shift with a cyclical overlay. The trend's direction is structural; its path will be cyclical.
A purely cyclical copper rally is mean-reverting. It is driven by a temporary demand impulse or a supply interruption that gets fixed: a mine reopens, inventories rebuild, prices fall back. The 2020-2021 copper surge, which took the metal from around $4,600 a ton to above $10,000, looked structural at the time but proved largely cyclical because the demand driver, pandemic-era stimulus and restocking, faded and supply eventually responded.
The current setup differs in three ways. First, the demand is capital-committed rather than sentiment-driven. Grid and data-center buildouts have permitting and construction timelines measured in years; once a transformer order is placed, the copper is needed regardless of the monthly industrial print. Second, the supply response is structurally slower. New copper mines take a decade or more to permit and build, and ore grades at existing mines are declining, meaning more rock must be moved to produce the same metal. Third, the inventory buffer that once absorbed shocks has thinned. LME stocks below 210,000 tons leave little cushion for any disruption, and the market has already demonstrated how quickly a draw of 90,000 tons can move the price.
The cyclical component is real, and it is the risk investors should respect. Copper has risen more than 10 percent in six weeks, and that pace invites profit-taking. If the U.S. dollar strengthens or global growth data disappoints, the metal can give back a portion of the move without the structural thesis being wrong. The correct read is that the trend is structural in direction but cyclical in its path, which means the disciplined posture is to buy weakness rather than chase strength.
The Counter-Thesis: Goldman's Surplus Call and the Bear Case
The strongest argument against the bull case comes from Goldman Sachs, which maintains a forecast for copper to average $12,650 a ton in 2026 and expects a 490,000-ton surplus for the year. That is a direct contradiction of the deficit forecasts from the ICSG and J.P. Morgan, and it cannot be waved away. Goldman's logic is that continued global surplus will prevent prices from exceeding $11,000 for a sustained period, even as demand from the grid and power infrastructure keeps a floor under the market in the $10,000-$11,000 range.
The divergence between Goldman's surplus and the deficit forecasts is not a data error; it is a disagreement about the timing of the supply response. Goldman is effectively betting that mine output and recycling will ramp fast enough to meet demand, while the deficit camp bets that concentrate constraints and project delays will keep supply inelastic. History sides cautiously with the deficit camp: copper supply has consistently disappointed relative to forecasts over the past five years, while demand from the energy transition has consistently surprised to the upside. But Goldman is right about one thing: if the surplus materializes as projected, the current price level is unsustainable.
There is also a macro bear case that operates independently of the supply-demand balance. J.P. Morgan has noted that copper prices could fall to $11,100-$11,200 a ton if bearish macro scenarios play out, driven by geopolitical risk and higher energy prices. A deep global recession would cut copper demand across construction and manufacturing, overwhelming the structural demand from electrification in the near term. That is the genuine risk to the thesis, and it is why the call is not one-sided. The energy transition is a multi-decade trend, but it does not immunize copper from a cyclical downturn.
The falsifying signal is specific and observable: if LME copper inventories rebuild above 300,000 tons while prices remain above $13,000, or if the ICSG revises its 2026 deficit forecast back to surplus, the structural-tightness thesis is wrong and the rally should be treated as cyclical. Until then, the inventory draw is the single most important data point in the market, and it currently points up.
The Second-Order Trade: Mining Stocks Have Not Caught Up
Here is the part of the argument that matters most for portfolio positioning. Hambro has previously noted that mining stocks have not fully kept up with the rapid rise in metals prices, including copper, creating attractive opportunities for stock investors. That gap is the second-order implication of the copper thesis, and it is where the asymmetric payoff sits.
When a commodity rallies on a structural deficit, the sequence is predictable: the commodity price rises first, then the miners' margins expand, and only then do the equities re-rate. The market is in the middle of that sequence. Major diversified miners have posted strong gains, with BHP up 36 percent this year and Rio Tinto up 25 percent as of late May, but those moves lag the percentage gain in the copper price itself. The reason is familiar to resource investors: generalist capital remains underweight the sector, and many mining companies are too small to absorb institutional mandates, a relevance problem that Hambro has said could drive a fresh round of industry consolidation.
The implication is that if the deficit confirms, miners offer leveraged exposure to the same thesis with room to close the valuation gap. The risk is the mirror image: if the deficit fails to materialize, miners fall faster than the metal, and the lag that looks like opportunity becomes a value trap.
What to Watch: The Signals That Decide the Trend
The outlook splits cleanly by time horizon, and conflating them is the most common mistake investors make with copper.
In the short term, copper is vulnerable to a technical pullback. The metal has risen from the low $13,000s to nearly $15,000 in roughly six weeks, and the pace of that move is not sustainable without consolidation. A retreat toward $13,500-$14,000 would be healthy and would not damage the thesis; it would be the cyclical path expressing itself within a structural uptrend.
In the medium term, the 2026 balance is the key. The ICSG's 150,000-ton deficit and J.P. Morgan's 160,000-ton deficit are small relative to a 28.7-million-ton market, but small deficits in tight markets produce outsized price moves because the marginal ton sets the price. The scenario to watch is whether the deficit widens into the second half of the year as Chinese demand picks up and concentrate constraints bite at smelters, pushing treatment charges lower and forcing production cuts.
In the long term, the structural case strengthens. S&P Global has estimated that the copper supply deficit could reach 10 million metric tons annually by 2040 as demand surges 50 percent to 42 million metric tons. That is the endpoint of the electrification trend, and it is why every cyclical dip is being bought by long-only investors with decade-long mandates. The gap between a 150,000-ton near-term deficit and a 10-million-ton long-term shortfall is the space in which this trade lives.
The base case is that copper holds above $13,000 and grinds higher toward $15,000-$16,000 as the 2026 deficit confirms. The upside case is a supply shock, such as an escalation of the Strait of Hormuz disruption or a major mine outage, which could push the metal toward $17,000. The downside case is a bearish macro scenario with a strong dollar and weak Chinese demand, which would take copper back toward $11,000-$12,000.
The watchlist is concrete: monthly LME inventory reports, the ICSG's next balance update, Chinese refined imports and smelter treatment charges, and any revision to Goldman's surplus forecast. The trend can continue, as BlackRock argues, but only as long as the warehouses keep emptying.
Copper's rally is not a bet on growth returning; it is a bet on growth changing shape. The metal that powered the industrial age is being repriced for the electrified one, and the market has not yet decided whether the new shape is permanent. The inventory data, for now, says it is.
