Global metals markets — both base and precious — have seen powerful rallies and a surge in trading activity since the start of the year, with many materials hitting all-time peaks. That jump had already prompted other measures by commodities exchanges to tackle market risks.
(Jan 26): Tin retreated from a record after the Shanghai Futures Exchange announced restrictions on positions for some clients suspected of not properly disclosing their ultimate ownership.
Three groups of clients — numbering sixteen in total — would be subject to one-month limits on opening new positions, as well as curbs on withdrawing funds from both the tin and silver markets, the bourse said in a statement. Tin slumped more than 6% in London while the action by China’s top commodities exchange prompted other metals including copper to soften.
