The Escondida union received 95% of the votes in favor. This figure may seem alarming, but if you have actually visited the project site in Chile or handled maritime shipping, you will understand that this is nothing more than a standard procedure before the labor and management sides openly confront each other. The Chilean mining unions perform such a show every few years, seeking authorization to negotiate for performance bonuses with BHP. Converting the price negotiations on the table directly into production reduction analysis for commodities, the accounting is not done this way.
To calculate this copper shortage, one must first pass through the legal framework of Chile and the physical laws of maritime transportation.
After the vote was passed, Chile's labor law mandates that both sides enter a government mediation process for five working days. If the parties' attitudes soften at the mediation table, this period can be extended by another five days. That means for the entire next week or two, the trucks in the mines will still be running, the grinding mills in the beneficiation plants will still be roaring, and not a single ton of ore will be missed. The fluctuating market movements on the screen during this stage are all emotions in the minds of traders, having nothing to do with the physical world of copper. If both sides reach an agreement on the dividend amount and sign the contract during the mediation period, the impact of the 95% approval votes on actual supply will be zero.
To put it another way, even if the mediation really broke down and the workers collectively locked themselves out, the physical industrial chain would not feel the "copper shortage" the next day. The main export product of Escondida is copper concentrate. It is extracted from mines in the Atacama Desert, mixed into slurry and transported through pipelines to the port for shipment across the Pacific to smelting plants in China or Europe. This single maritime journey alone takes three to four weeks.
This means an extremely cruel physical time lag: Even if the mines immediately run out of copper today, the cargo ships already at sea, the goods waiting to be unloaded at the port, can still support the downstream operations for half a month or more. The first pain to be felt is not by the copper plates' cable factories, but by the purchasing managers of the smelting plants - when they see the signs of a supply cut at the source, they will instinctively rush to the spot market to grab spot orders and directly drive the spot TC (processing fee) through the roof. The first cut is to the profits of the smelting plants, and the "copper" in the physical world is actually not a single ton less.
The true supply chain breakdown must be calculated by using the calendar to determine the duration of the strike. The regular copper concentrate inventory in domestic mainstream smelting plants is generally around 30 to 40 days. If the strike lasts only two weeks, it is just a consumption of some safety inventory for the smelting plants, or even they may take the opportunity to shut down for a few days under the pretext of equipment maintenance, while negotiating with the union; only when the strike actually stretches to more than a month, with the complete interruption of maritime replenishment supplies and the depletion of ore in the port stockpiles, will the smelting plants be forced to reduce their production rates.
At this point, the impact on the output of refined copper will only penetrate to the real end-users through the purchase orders of wire and cable factories and new energy vehicle manufacturers. The story of the supply side of commodities is never like flipping a switch and instantly cutting off the power. Without experiencing a continuous blockade for more than a month, this nationwide strike, which is a wild celebration, is ultimately likely to be just a fluctuation in the profit statement of the smelting plants on the balance sheet, and a hard confrontation between the mining companies and the union when distributing the money.
Rather than rushing to calculate a few thousand tons less of copper when the headline news comes out, it is better to keep a close eye on the statement issued by the Chilean Labor Department at the end of the five-day mediation period. That is where the stopwatch truly starts to count down.
