Data released by the London Metal Exchange (LME) showed that LME copper inventories declined at an accelerated pace last week, with the latest inventory level reaching 179,375 mt, a new low in ten and a half months.
The latest data released by the Shanghai Futures Exchange indicated that during the week of May 16, SHFE copper inventories rebounded somewhat, with weekly inventories increasing by 34% to 108,142 mt. International copper inventories increased by 24.33% to 17,117 mt.
Last week, COMEX copper inventories continued to rebound, with the latest inventory level reaching 169,664 mt, marking a new high in over six years.
Note: Generally speaking, a continuous decline in inventories at domestic and overseas exchanges will support futures prices, while the opposite will have a bearish impact on futures prices.
