LONDON, Aug 16 Zinc’s sharp rally and looming market deficit has fed speculation that major producers such as Glencore may reverse output cuts, but analysts caution that is unlikely to happen soon.
Only when stocks of concentrate and metal sink to levels where higher prices can be sustained will large producers look at restarting capacity, they say. Benchmark zinc on the London Metal Exchange has climbed nearly 60 percent from January’s multi-year lows to around $2,300 a tonne, its highest since May 2015.
Many zinc mines have been shut or mothballed over the past couple of years, but prices did not really take off until this year when deficit expectations intensified with the closure of the Century mine in Australia and Lisheen in Ireland.
