After an interruption due to technical issues lasting nearly three hours, the London Metal Exchange's LME Select electronic trading platform resumed trading at 17:30 Greenwich Mean Time on Monday. Prices for metal contracts on the London Metal Exchange, including copper, aluminum, lead, zinc, nickel, and tin, stopped updating on the London Stock Exchange Group's Workspace platform shortly before 15:00 Greenwich Mean Time. As the oldest and largest industrial metal trading market in the world, the London Metal Exchange stated that its main electronic matching engine had experienced a malfunction, causing the electronic trading to enter a technical pause state. In-person trades remained normal throughout the incident. The London Metal Exchange stated in a release, "Although all closing prices were generated according to exchange procedures, the interruption was declared due to system malfunction impacting market participants' ability to hedge at relevant prices." The exchange had previously mentioned the possibility of using backup methods to generate closing prices. On January 30, the London Metal Exchange also delayed the opening of electronic trading by an hour due to technical issues. The exchange announced that the electronic market had restarted on a backup matching engine at 17:30 Greenwich Mean Time on Monday, and trading would proceed as planned until 19:00 Greenwich Mean Time.
