What is the London Metal Exchange (LME)

The London Metal Exchange is the world’s largest non-ferrous metal exchange. The price and inventory of the London Metal Exchange have an important influence on the production and sales of non-ferrous metals worldwide. In the mid-nineteenth century, Britain was the world’s largest producer of tin and copper. With the passage of time, industrial demand continued to grow, and Britain urgently needed to import large amounts of industrial raw materials from foreign mines. Under the conditions at the time, due to the irregular arrival time of the freighters transporting ore across the ocean, the price of metals fluctuates greatly. Metal merchants and consumers have to face huge risks. In 1877, some metal trading merchants established London Metal The exchange has also established a standardized trading method. Since the beginning of this century, the London Metal Exchange has begun to publicly publish its transaction price and it has been widely used as a quasi-price in the world’s metal trade. 70% of all copper production in the world is traded on the basis of the official price announced by the London Metal Exchange. During the working day of each week, the trading time of all ferrous metals in the London Metal Exchange is as follows: 11:40 GMT, starting the morning on-site trading; each trading product rotates for 5 minutes each. At 12:20, after all 8 kinds of metals are traded in sequence, there will be a 10-minute break; at 12:30, the second trading in the morning will start, and each type will still be traded in sequence for 5 minutes. Because the second floor trade in the morning determines the official settlement price of the day, it is of special significance. After the official settlement price is reported, that is, around 13:15 in the afternoon, the over-the-counter price starts trading and continues until 13:30. During this period, 8 metal varieties were traded at the same time. In the morning, the on-exchange trading ends after the over-the-counter price closes, and the trading is transferred indoors. The second session of the day on the London Metal Exchange began at 15:10 in the afternoon. The trading in the afternoon is similar to the trading in the morning. After the end of 16:35, the over-the-counter trading will be carried out immediately until 17:00, which lasts for a total of 25 minutes. The difference between the morning and afternoon on-site trading is that there is no important procedure for the official settlement of the settlement price in the afternoon on-site trading.
