LONDON, Sept 19 (Reuters) – A sharp rally in zinc prices is posing the threat that industrial users will find ways to substitute the metal with cheaper alternatives or use less, curbing overall consumption.
High prices may also dampen a nascent move by Chinese automakers to use more zinc for galvanising, while the Western car sector could employ thinner coats of zinc alloys to help meet tough emission rules by cutting vehicle weight.
“We expect zinc prices to carry on going up for at least another 12 months, so I think there’s clearly a growing risk of demand destruction in some shape or form,” said analyst Andrew Thomas at consultancy Wood Mackenzie. Benchmark zinc on the London Metal Exchange has doubled since January last year, hitting a peak of $3,231.75 a tonne in late August, the highest in a decade.
