Chile is being affected by a strong winter frontal system, with the main impact expected to focus on July 16–17 and possibly persisting through July 20–21. This weather event shows pronounced regional differences. High-altitude and mountainous areas in northern mining regions such as Antofagasta and Atacama will experience moderate to heavy snowfall and strong winds, while central to southern Chile faces persistent heavy rainfall, with an increased risk of localized flooding, landslides, and mudslides.

The Chilean government has activated preventive emergency responses, and mining authorities have also communicated contingency plans with major mining enterprises. According to SMM’s discussions with local industry insiders, the heavy snowfall and rainfall may cause short-term disruptions to road transportation and port loading in some mining areas, posing a risk of delays to the export pace of copper concentrates and copper cathode. The actual impact will still depend on the duration of the weather and the operational status of major mines.

Nan Ya Raises Copper Clad Laminates Prices by 20% Amid Rising Raw Material Costs and AI Demand

On August 14, Nan Ya issued another price increase notice. Driven by rising raw material costs for copper foil, fiberglass cloth, and resin, as well as tight supply and demand in electronic materials fueled by AI computing demand, prices of copper clad laminates and base materials will be raised by 20% effective September 1. Nan Ya stated that the electronic materials industry is currently in a golden cycle, with capital expansion by US cloud vendors and AI server demand driving demand for mid-to-high-end materials, while limited new capacity has created a supply-demand gap. The news pushed Nan Ya's stock to the daily limit intraday.

High Copper Prices Lead to Reduced Cable and Wire Inventories, Operating Rates Expected to Fall Further

In terms of cable and wire inventories this week, constrained by high copper prices, cable and wire enterprises generally adopted a rigid-demand purchasing strategy, locking in prices for small restocking only during minor copper price pullbacks. As a result, raw material inventories edged down 0.49% month-on-month. To ease inventory pressure, downstream enterprises prioritized drawing down finished goods inventories, which fell 2.33% month-on-month. Looking ahead to next week, the weak demand pattern across all segments is unlikely to reverse, and the industry lacks short-term recovery momentum. Under the dual pressure of high copper prices and off-season demand, SMM expects the copper cable and wire operating rate to fall a further 1.18 percentage points month-on-month to 61.08% next week (August 14–August 20), representing a year-on-year decline of 7.8 percentage points.

Copper Cable and Wire Operating Rate Falls to 62.25% Amid High Prices and Weak Demand

This week (August 7–August 13), SMM's copper cable and wire enterprise operating rate came in at 62.25%, down 1.4 percentage points month-on-month and 7.05 percentage points year-on-year. Copper prices remained elevated throughout the week, continuing to suppress downstream purchasing enthusiasm. Combined with overall weak terminal orders and no substantive improvement on the demand side, the industry's production load continued to decline.
