Oct 20 (Reuters) - Industrial metals declined on Wednesday as China's plan to bring down coal prices eased worries about metals supply shortage and investors booked profits after recent strong gains.
Three-month copper on the London Metal Exchange fell 1.3% to $10,015 a tonne by 0737 GMT, while the most-traded November copper contract on the Shanghai Futures Exchange dropped 2.5% to 73,380 yuan ($11,476.92) a tonne.
ShFE zinc tumbled 6.5% to 25,415 yuan a tonne, ShFE aluminium shed 6.3% to 22,805 yuan a tonne, ShFE tin dropped 2% to 283,520 yuan a tonne and LME aluminium fell 1.6% to $3,063 a tonne.
China's state planner said on Tuesday it was studying ways of intervening in high coal prices and would take all necessary measures to bring them back to a reasonable range.
The most-active Dalian coking coal contract and coke futures both dropped 9% on Wednesday, while China's coal futures fell 8% to their downward limit in night trading on Tuesday.
The sharp drop in coal prices had an "emotional impact" on non-ferrous products, said Huatai Futures in a report, adding that a build in zinc inventories also suppressed prices of the metal used in galvanising steel.
ShFE zinc stocks
The power crunch in China and electricity price hikes in Europe have raised concerns of supply shortages in base metals, some of which are already seeing multi-year low inventories.
Zinc surged 20.4%, copper jumped 9.8% and aluminium gained 6.9% on the LME last week.
