China has tightened gold trading rules in Shenzhen after sudden market shocks and illegal activities. Ten government bodies, including the Shenzhen financial regulatory bureau and the local People’s Bank of China, issued a joint notice on Friday. The notice bans illegal trading like irregular pricing and leveraged deals. It also stops false ads such as "gold will surge" claims that mislead investors. Gold prices have been swinging but recently rose from $4,400 to about $4,969 per ounce. The regulators warned against illegal fundraising schemes dressed as gold custody, leasing, or repurchase deals. Unauthorized gold selling and diverting gold into schemes are also banned. Live-stream sales of gold products with false claims or hidden fees are now prohibited. Financial institutions must not handle gold services without approval and must report big or odd transactions promptly. They should refuse services to unregistered or illegal merchants. Individual investors cannot join illegal pre-priced trades or unlicensed schemes. Creating or using illegal gold trading apps is forbidden. These measures aim to protect consumers and ensure a healthy gold market in Shenzhen.
