At present, domestic futures companies with branches in Hong Kong can act as agents for futures account, and domestic investors can directly handle it through the domestic sales offices of these companies. However, because the foreign futures settlement currency is US dollars, investors need to go to the bank to convert RMB into US dollars before they can deposit. The free exchange limit is 50,000 US dollars, which is about 300,000 RMB. Deposits are made through account remittance provided by futures companies, and there is still no silver-to-silver transfer business.
