Copper Faces Sentiment vs. Supply-Demand Battle as Chinese Demand Slumps and Smelters Struggle

The immediate catalyst for copper's bounce was a shift in geopolitical risk. President Trump announced a five-day postponement of U.S. strikes on Iranian energy infrastructure following what he described as "productive" talks with Tehran. This move lifted financial markets broadly and prompted a 2.7% rise in copper futures to $12,157.50 a metric ton.

Yet this short-term relief contrasts sharply with the metal's underlying weakness. Even as the ceasefire talk sparked a rally, copper was on track for a nearly 10% monthly loss in March, marking its worst performance since July 2025. The price action highlights a key tension: while a potential de-escalation offers a near-term sentiment boost, it does not erase the longer-term supply-demand pressures building from the conflict.

The broader trend of weakness stems from the conflict's tangible economic costs. The war has disrupted oil and LNG shipping, raising energy prices that directly hit the industry. Copper operations, from diesel-powered mines to grid-dependent smelters, face higher costs and weaker profitability due to this uncertainty. This fundamental pressure had already pushed prices down, setting the stage for a volatile reaction to any geopolitical news.

Assessing the Fundamental Shift: Supply, Demand, and Inventories

The geopolitical ceasefire provided a temporary financial flow, but it does not alter the physical market's fundamental imbalance. Goldman Sachs Research expects a continued global surplus of supply to cap prices below $11,000 per tonne for a sustained period in 2026. This forecast is anchored in two critical realities: a sharp drop in Chinese demand and a stressed midstream supply chain.

Chinese demand, a key driver of global copper consumption, fell to -8% year-on-year in the fourth quarter of 2025. This weakness persisted even after the initial stimulus and tariff front-loading that had briefly boosted imports earlier in the year. The drop signals that the economic engine for copper in the world's largest consumer is cooling, directly pressuring prices from the demand side. A ceasefire in the Middle East does nothing to reverse this domestic slowdown.

Meanwhile, the supply chain itself is under strain. The midstream sector, which includes smelters, is showing clear signs of stress. Despite record-high copper prices, smelter fees have fallen to record lows, with annual treatment and refining charges hitting $0 per tonne in January. This dynamic is a direct result of a surge in smelter capacity additions in China that has outpaced the growth in copper concentrate production. The imbalance means smelters are competing fiercely for raw material, driving down their input costs and highlighting a bottleneck in the system that a geopolitical resolution cannot fix.

The bottom line is that the market's physical balance remains oversupplied. The recent rally is a sentiment play, not a signal of a new supply-demand equilibrium. Until Chinese demand recovers or supply disruptions become more severe, the structural surplus and midstream pressures will keep prices contained. The ceasefire offers no relief from these underlying conditions.

Financial Flows vs. Physical Market Signals

The recent price action underscores a clear divergence between financial flows and the physical market. Copper fell 6.7% last week, its steepest drop since April 2025, as the ongoing Middle East war sapped risk appetite and raised recession concerns. This decline was part of a broader sell-off, with the dollar index rising on safe-haven demand as ceasefire hopes dimmed. The dollar's strength supports lower prices for dollar-denominated commodities, but this is a financial flow, not a driver of physical demand.

Viewed another way, this volatility is a signal of underlying stress. The sharp drop reflects a market pricing in the dual threat of global growth slowdown and persistent inflation, a combination that pressures industrial metals. Analysts note copper prices haven't reached a bottom yet, as the market weighs these macroeconomic headwinds.

Yet within this financial turbulence, a different story is emerging on the physical side. The drop below 100,000 yuan ($14,485) on the Shanghai Futures Exchange prompted "significant" purchases from Chinese fabricators who are seeing full orders into next month. This demand resilience at lower prices is a crucial physical signal. It suggests that at current levels, Chinese end-users are stepping in to secure material, which will support domestic prices and could help stabilize the market from the bottom up.

The bottom line is that the financial flows-driven by geopolitical uncertainty and a strong dollar-are amplifying price swings. But the physical market is showing a more nuanced picture: a stressed supply chain and cooling Chinese demand create a ceiling, while targeted buying at low prices provides a floor. The recent volatility is a symptom of the tension between these forces, not a new trend.

Catalysts and Risks: What to Watch for the Thesis

The market's current duality-between a stressed physical supply chain and cooling demand-creates a setup where specific events could quickly shift the balance. The key is to watch for developments that either accelerate the structural surplus or trigger a supply shock.

First, monitor the resolution of the Middle East conflict. A prolonged disruption would raise energy costs for miners and processors, adding to the inflationary pressure already sapping risk appetite. This would likely keep prices volatile and could reinforce the recession fears that analysts say have not yet been priced in. Conversely, a swift ceasefire would ease those fears, potentially providing a sustained sentiment boost that could help prices hold above the $10,000-$11,000 range Goldman Sachs expects for 2026. The recent five-day postponement of strikes was a positive signal, but the market remains sensitive to any backtracking.

Second, track Chinese economic data and policy stimulus announcements. The -8% year-on-year drop in Chinese demand is the primary driver of the current surplus. Any signs of a recovery in manufacturing or construction activity would directly challenge the structural weakness. Similarly, new stimulus measures aimed at boosting infrastructure or consumer spending could reverse the demand trend and tighten the market from the demand side.

Finally, watch for new mine production outages and smelter capacity utilization rates. The midstream sector is already stressed, with record-low smelter fees indicating a bottleneck. Further supply-side tightening, such as unexpected outages at major mines or a drop in smelter utilization due to feedstock shortages, could counter the structural surplus and provide a physical floor for prices. The recent 6.7% weekly drop shows how quickly sentiment can turn, but sustained buying from Chinese fabricators at lower prices suggests a bottom may be forming if supply disruptions materialize.

The bottom line is that the thesis hinges on these catalysts. Without a shift in Chinese demand or a supply shock, the market will likely remain range-bound. But any development that disrupts the supply-demand calculus could move the market decisively.
