In the world of commodities, there are many nicknames. "Copper Doctor" is probably the most widely known one. When many people first hear this name, they might think it's the nickname of some scholar. In fact, it belongs only to the metal copper.
This title did not come from the laboratory; it was gradually established in the trading market. In the early years of the global industrialization wave, copper permeated almost all physical industries. Factories needed to wire when starting up, infrastructure construction required pipes when laying tracks, and houses needed wires for construction. As long as the real economy showed signs of expansion, enterprises would purchase copper in advance, driving up the price; when the economy slowed down and orders shrank, copper purchases would be reduced first, and the price would subsequently fall.
The applications of copper are closely tied to physical production, and price fluctuations often reflect the economic conditions of the macro economy in advance. It is like an observer that can read the economic cycle in advance. The market bestowed upon it the title of "Doctor". People are accustomed to looking at copper prices to predict the direction of the global economy, as if a movement in copper prices could reveal the prosperity or decline of the economy in the future.
However, in recent years, more and more people have discovered that the Copper Doctor seems to have "failed".
It's not that copper is no longer useful; it's that the logic of world supply and demand has become more complex. In the past, the demand for copper mainly came from traditional infrastructure, real estate, and manufacturing. The linkage between demand and the macro economy was very direct. Now, there is an additional layer of complex variables: the transition to new energy.
Solar power stations, wind power bases, energy storage stations, and new energy vehicles all require a large amount of copper. This new demand is not completely synchronized with the cycles of traditional real estate and manufacturing. Even if the traditional economy is weak, the continuous implementation of new energy projects will still consume copper. Demand no longer follows the old economic cycles, and a single copper price naturally cannot simply correspond to the overall economic prosperity or decline.
The supply side is also challenging the old judgment framework. Copper mines are mostly concentrated in a few countries, and the production cycle of mines is long. They also have to deal with various uncertainties such as geopolitics, environmental protection, and community conflicts. The release rhythm of mine production capacity does not always align with the global economic cycle. Moreover, the volume of recycled copper is increasing year by year, and the supply flow of second-hand copper is also quietly changing the supply structure of copper.
There is also the variable of inventory, which is often overlooked. Visible inventory is just the tip of the iceberg. A large amount of copper is stored in smelters, traders, and processing enterprises' warehouses. Sometimes, fluctuations in the market price are merely hoarding or de-stocking in the trading环节, rather than a significant change in actual demand. If we still rely on the logic from decades ago and simply use the rise and fall of copper prices to predict the macroeconomy, it is very likely to make a wrong judgment.
However, we don't need to immediately take off the "Copper Expert" hat. It has not completely lost its effectiveness; it's just that the way of interpretation can no longer be as simple and crude as before. Copper price is still an important window for observing the real economy, but it is no longer a single indicator that can instantly tell whether the economy is good or bad.
In the past, looking at copper prices meant reading the economic cycle. Now, reading copper requires looking at a large number of variables such as traditional demand, new energy growth, mine production, recycled supply, and inventory flow.
The Copper Expert has not disappeared; it has just raised its reading threshold.
