Introduction to London Metal Exchange (LME)

London Metal Exchange is the largest non-ferrous metal exchange in the world. The price and inventory of London Metal Exchange have an important impact on the production and sales of non-ferrous metals all over the world. In the mid-19th century, Britain was the largest producer of tin and copper in the world. With the passage of time, industrial demand continued to grow, and Britain urgently needed to import a large number of industrial raw materials from foreign mines. Under the conditions at that time, due to the irregular arrival time of cargo ships transporting ore across the ocean, the price of metal fluctuated greatly, and metal traders and consumers had to face great risks. In 1877, some metal traders established the London Metal Exchange and established a standardized trading mode.

From the beginning of this century, the London Metal Exchange began to publicly publish its transaction price and is widely regarded as a quasi price of world metal trade. 70% of the world’s total copper production is traded according to the official quotation published by the London Metal Exchange. The non-ferrous metal trading time procedure of the London Metal Exchange on weekdays is as follows: the morning floor trading starts at 11:40 GMT; Each trading variety takes turns trading for 5 minutes. 12: 20.

After all 8 metals are traded in sequence, take a 10 minute break; 12: 30, start the second transaction in the morning, and each variety is still traded in sequence for 5 minutes. Because the second intra market transaction in the morning determines the official settlement price of the day, it is of special significance. After the official settlement price is quoted, i.e. around 13:15 p.m., the OTC price starts trading and lasts until 13:30. During this period, eight metal varieties were traded at the same time. In the morning, the on-site trading ends after the off-site price closes, and the trading is carried out indoors. The second session of the day on the London Metal Exchange began at 15:10 p.m.

The floor trading in the afternoon is similar to that in the morning. After 16:35, the OTC trading will be carried out until 17:00, lasting for 25 minutes. The difference between morning and afternoon floor trading is that there is no important procedure of officially announcing the settlement price in afternoon floor trading.
