[This blog post is an excerpt from a recent commentary at https://speculative-investor.com/]
Chile is by far the world’s largest copper-producing country, accounting for about 23% of global production. After that we have the Democratic Republic of the Congo (DRC) and Peru. Together, these three countries account for almost 50% of global copper production, a potential major problem in the making.
As discussed in the article posted HERE, the output of Chile’s copper mines is projected to fall 8%-9% this year, which would make 2026 the weakest year for this country’s copper production in at least two decades. Also, the article notes that the slump in Chilean copper production “adds to a string of mine disappointments around the world that have opened the door to the first annual decline in global mined-copper output since 2017, just as demand strengthens with increased investment in data centers and power infrastructure.”
One of the reasons for this year’s decline in Chile’s copper production, and a reason why this country’s production likely will be sub-par again next year, is the Super El Niño. As discussed HERE, “El Niño is weakening the high-pressure system that normally keeps storms away from central Chile, allowing more rain-bearing fronts into the region.” Previously we have focussed on the adverse effects of the Super El Niño on agriculture, but in Chile it also is adversely affecting mining. There may be similar issues in Peru, the world’s third-largest copper-producing country, but even if its copper mines are not impacted by extreme El Niño weather it appears that Peru’s copper production has plateaued.
In the DRC, the world’s second-largest copper-producing country, there could be weather-related reductions to copper output associated with the Super El Niño, but the main threat at the moment is that the country is in the midst of the fastest-growing Ebola outbreak in its history, with more than 10,000 confirmed cases to date. In addition to being a major copper-producing country, the DRC is a major producer of tin, another metal that is critical for the datacentre building boom.
There have been large corrections in the prices of some industrial metals over the past several months, but the following charts show that the prices of copper and tin remain near their highs. This is most likely because production constraints associated with weather and disease are preventing relatively high prices from causing an adequate supply response to rising demand.


We would be bullish on the multi-year prospects for copper and tin based solely on projected demand growth, but adding the aforementioned production problems into the mix makes us even more so.
