SHANGHAI, Mar. 18 (SMM) – Investors will remain cautious before any decision next week by the US Federal Reserve regarding March interest rates. Since economic data from the US continues to show the US economy gathering steam, zinc prices are likely to stop falling since a stronger US dollar index will continue to weigh on zinc prices. LME zinc prices are expected to move between USD 1,960-2,020/mt in the coming week. However, since zinc reserve purchases by the SRB and improving downstream market allowed domestic zinc prices to resist declines, SHFE 1306 zinc contract prices should move between RMB 15,150-15,400/mt, with spot discounts against SHFE 1306 zinc contract prices between RMB 250-300/mt.
