SMM May 8 update:

Spot premiums in Ningbo continued to rise this week, with the weekly average price up 55 yuan/mt WoW. As of this Friday, Ningbo spot prices against the SHFE 2606 contract were quoted at a premium of 50 yuan/mt, with a premium of 60 yuan/mt against Shanghai. Zinc ingot inventory in Ningbo continued to decline. Few traders made shipments during the week, and traders' spot quotations continued to rise. However, some large manufacturers had stockpiled heavily earlier and mostly stayed on the sidelines this week. Other manufacturers also made few purchase inquiries, and overall transaction performance was mediocre. With cargo volumes remaining low, spot premiums are expected to stay firm next week.
