Profit-taking LME copper closed down | Zinc inventory rose sharply and fell.

(LME) copper futures on the London Metal Exchange fell slightly on Tuesday as speculators took profits after a recent rally at a time when the energy market generally fell. Zinc futures, on the other hand, fell sharply by more than 5 per cent, dragged down by a sharp increase in inventories.

17:00 London time (00:00 Beijing time)), LME copper for three-month delivery fell 0.46 per cent, or $46.50, to $10149.50 a tonne, after rising 2 per cent earlier to hit $10402.50 a tonne.

LME copper prices jumped 15 per cent in less than two weeks, closer to the record high of $10747.50 set in may.

Industrial metal users are trying to buy raw materials as metal inventories fall and some LME base metal smelters suspend production as energy prices rise.

Us natural gas futures fell near four-week lows on Tuesday, with oil prices slightly lower.

Spot copper in LME hit a record high of $1103.50 a tonne on Monday against three-month copper, up from $55 a tonne a week ago, a sign of recent tight inventories. The rally fell back to $740 a tonne on Tuesday.

The bank expects aluminium prices to average $3300 a tonne in the fourth quarter of 2021 and $2900 in 2022.

The investment bank said: "the global aluminium market should continue to be tight and aluminium production outside China should also decline because of high energy prices. We expect supply conditions in some metal markets to deteriorate temporarily. So metal prices are likely to remain high or rise further in the coming months. "

Indonesia is planning to "hit the brakes" on all raw material exports to attract investment in land-based resource processing and create jobs, Indonesian President Joko Widodo said on Tuesday.

Indonesia has banned the export of a variety of raw ores, such as nickel, tin and copper, to encourage downstream industries, including the production of electric car batteries and aluminum.

The government is currently conducting a study on downstream sales of other commodities with the long-term goal of not just selling raw materials, he said.

A new policy is expected next year, he said.
