SHANGHAI, Dec. 16 (SMM) – Lasting worries towards the European debt crisis combined with a plunge in LME tin prices overnight restarted the downward run of Shanghai spot tin on December 15th. Mainstream Yunxi, Yunxiang and Nanshan branded tin plus a small amount of Yunshan branded tin were traded between RMB 157,000-161,000/mt. While branded tin smelters were holding quotations firm, mainstream traded prices were near RMB 160,000/mt as a result of lower-priced supply by other goods holders. Shanghai spot tin prices nevertheless are more stable compared with LME tin prices. The traded volume remained limited as the downstream demand turns weaker at year’s end. Rumors were heard that some solder producers already ended this year’s production due to light order volumes.
