SHANGHAI/BEIJING, Nov 27 (Reuters) - Three of China's major state-owned banks announced on Friday they will suspend the opening of new accounts for their precious metal investment products from Saturday amid increased volatility in global and domestic precious metal prices.

Industrial and Commercial Bank of China (ICBC) said in a notice on its website it would suspend the opening of new individual gold, silver and other precious metal investment trading accounts from Saturday via all channels, including over-the-counter and online or mobile banking.

"Affected by the global epidemic situation and the international political and economic situation, international and domestic precious metals price continued to show volatility, market risks and uncertainties increased," ICBC said.

Bank of Communications and China Construction Bank also suspended new account openings for their precious metal trading and investment products from noon on Saturday and from Monday, respectively.

The banks warned investors to pay attention to market and volatility risks and to manage trading and conduct investment transactions prudently and rationally, according to statements released on Friday.

Spot gold prices began sliding after Nov. 9 as news of the first successful, late-stage novel coronavirus vaccine trial prompted investors to dump safe-haven bullion and flock to riskier assets. They are down nearly 4% this month.

Bank of China and Bank of Communications in early November had already warned investors they could restrict trading of their precious metal and foreign exchange products if the U.S. presidential election on Nov. 3 fueled market volatility.
