Approaching Typhoon "Bavi" Triggers Stockpiling Spree, Center of Shanghai Spot Copper Premiums Shifts Higher

[SMM Shanghai spot copper] According to the Central Meteorological Observatory, the 9th typhoon this year, "Bavi," has intensified into a super typhoon. It is expected to approach the eastern sea areas of China around July 10, with a high probability of making landfall in east China. Affected by this, downstream copper semis processing plants in Jiangsu and Zhejiang were concerned that the subsequent strong winds and heavy rain brought by the typhoon could disrupt logistics, transportation, and production schedules. As a result, they concentrated on stockpiling purchases in advance, pushing the overall center of Shanghai spot copper premiums higher. Currently, transaction prices for domestic standard-quality copper are at premiums of around 70 yuan/mt to 90 yuan/mt.
