Trading has been halted for all contracts on the London Metal Exchange in London, and retailers cannot place orders. The halt occurred at 15:44 Swedish time and affects trading in metals including aluminum, copper, and zinc. According to unconfirmed reports, a technical fault is likely behind the issue.
A spokesperson for the exchange stated in an email to Bloomberg that they are aware of a problem and working to resolve it as quickly as possible. The cause remains unclear. The disruption comes during a volatile period for metals, as the war in Iran is reportedly disrupting flows of industrial metals, including aluminum and zinc, and making both short- and long-term price developments more uncertain.
