SHANGHAI, Apr. 15 (SMM) – SHFE lead prices slumped on Monday, further undermining selling interest of cargo holders in spot lead markets. Quotations were rare, with Chihong Zn & Ge and Nanfang quoted at RMB 14,050/mt, RMB 150/mt lower than the SHFE 1306 lead contract price. Tongguan was offered at RMB 14,030/mt, down RMB 200/mt from spot lead prices last Friday. Downstream buyers were bearish and unwilling to purchase.
