Due a firm US dollar index and concerns of a possible military attack on Syria by western countries, LME tin prices overnight plummeted to USD 21,350/mt, closing at USD 21,370/mt, down USD 237/mt. The US dollar index was boosted by positive US economic growth and decreasing initial jobless claims last week, which increased concerns that the Fed will scale back QE3 soon.

LME tin prices are expected to find support at USD 21,200/mt today, and spot prices in Shanghai should move between RMB 141,500-144,500/mt.
