Copper Holds Firm as Supply Curbs Offset China Doubts

Quick Take

Copper is holding up better than a simple growth-scare narrative would suggest. On the London Metal Exchange, the 3-month closing price was $13,284.50 on 15 April, up 1.77% on the day, which shows the market is still willing to pay for supply risk even after the volatility of the first quarter.

The key reason is that the market is again focusing on supply friction. Fresh pressure on smelters, tight concentrate conditions, and disruption risks in producing regions are helping to support prices, even though the demand side is not sending a completely bullish signal.

What Changed

The most important new development is in China’s smelting sector. Reuters reported on 14 April that Chinese copper smelters may press ahead with production curbs after Beijing moved to halt sulphuric acid exports from May, a step that could hurt by-product earnings and push some smelters to accelerate maintenance or reduce output. Reuters also noted that spot treatment charges for copper concentrate have fallen to historic lows, adding to the squeeze on smelter profitability.

That matters because copper does not need a full-blown supply collapse to stay firm. It only needs the market to believe that refined output growth may slow just as raw-material tightness is becoming harder to ignore. This is an analytical inference based on the Reuters reporting on treatment charges, acid pricing, and potential production curbs.

Why Supply Is Giving Copper a Floor

Supply stress is not just a China story. Reuters reported on 13 April that copper and cobalt miners in the Democratic Republic of Congo were cutting chemical use because the Iran war had disrupted shipments of sulphuric acid and sodium metabisulphite, raising the risk of slower production and higher costs in one of the world’s key copper-producing regions. Reuters also reported that Codelco’s costs had risen by at least 10 cents per pound because of the same conflict-driven disruption.

There is also still evidence that underlying end-use demand has not disappeared. Reuters reported on 14 April that Aurubis expected U.S. copper demand to start reducing the unusually large Comex stockpile in coming months, with power, construction, and data centres helping to support consumption even as some sectors remain softer.

Why the Rally Still Looks Uneven

The problem is that copper is not getting a clean demand story from China. Reuters reported on 9 April that China’s net refined copper imports in February fell to 125,350 tons, the lowest monthly level since 2011, while imports in the first two months of 2026 dropped 25% year on year and exports more than tripled. Reuters said higher domestic production, larger inventories, and more moderate spot demand were all contributing to that shift.

That is why the current move still looks mixed rather than explosive. Supply tightness is real, but China is no longer behaving like a market that must absorb every high-priced ton from the rest of the world. This is an analytical judgment based on Reuters’ reporting on import weakness, export growth, and stock accumulation.

The Bigger Macro Backdrop Is Still a Constraint

The broader macro picture is also preventing copper from turning into a one-way bull market. Reuters reported on 13 April that China’s first-quarter GDP growth was expected to rebound modestly to 4.8%, but that the Iran war was dimming the rest-of-year outlook by pressuring margins and demand. That means copper still has to trade in a market where supply worries are rising, but growth conviction is not fully following.

That tension helps explain why copper can stay elevated without looking completely free on the upside. Industrial metals tend to respond well when supply risk and growth optimism rise together. Right now, only one of those legs looks clearly strong. This is an analytical inference based on the latest Reuters macro and metals coverage.

Near-Term View

My near-term view is that copper still has a firm floor, but the upside may stay choppy rather than clean. If Chinese smelter curbs deepen and producing regions remain under cost and logistics stress, the market has enough reason to stay supported. But unless China demand starts to look stronger again, the rally may continue to advance in bursts rather than in a smooth trend.

Conclusion

The main point is simple: copper is being held up by supply pressure more than by a broad demand boom. That is enough to keep the market firm, but not enough to remove every doubt. For now, copper looks supported, not fully unleashed.
