Copper prices on the London Metal Exchange rose 0.2% to $14,447 per ton, buoyed by supply concerns stemming from potential labor actions at major Chilean mining operations. The primary driver of price support comes from the threat of a workers strike at BHP's Escondida mine in Chile, which is the world's largest copper mine by production volume. The supply concerns were compounded by suspended mining operations at the facility following a worker fatality in an accident.
Additionally, two unions at Antofagasta's Centinela copper mine in Chile rejected a collective contract offer on Monday, according to Reuters reporting, creating further potential for labor disruptions in the South American copper-producing region. These developments have reinforced broader market concerns about copper supply availability at a critical juncture for the global market. On the supply side, LME warehouse stocks declined by 875 tons to 251,350 tons, though roughly half of that inventory is not readily available to the market, indicating tight supply conditions.
Meanwhile, COMEX copper stocks have risen to over 700,000 tons for the first time, presenting a contrasting picture to the tighter LME conditions. Market participants are closely monitoring incoming macroeconomic data, including manufacturing PMI figures from China and a series of US economic releases, for signals regarding demand trends and the trajectory of monetary policy. Copper restocking activity in China ahead of the country's week-long National Day holiday has been largely completed, which analysts expect will reduce supportive buying pressure from Chinese markets in the near term.
Recent economic data from China showed that industrial profit growth decelerated in August despite strength in technology manufacturing. Weak domestic demand has offset gains from the artificial intelligence sector, with Chinese firms facing reduced pricing power due to excess capacity across multiple industries. This situation leaves Chinese manufacturers increasingly reliant on export demand for growth, creating potential vulnerability to further demand deterioration.
Household income and consumption data will be closely watched as indicators of future industrial activity and copper demand within China. Source: ADM Investor Services International Limited market commentary, authored by J.P. Steiner.
