什么是“纸黄金交易”？有无相关英文表达？

纸黄金交易就是不做现货黄金交割的账面黄金交易，因此又称为“记账黄金交易”。与投资实物黄金一样，“纸黄金”是黄金投资的一种方式，因此它兼有长期保值和博取差价收益两种功能。

纸黄金交易盈利模式即通过低买高卖，获取差价利润。相对实物金，其交易更为方便快捷，交易成本也相对较低，适合专业投资者进行中短线的操作。纸黄金的发行一般是由黄金市场上资金实力雄厚、资信程度良好的商业银行、黄金公司或大型黄金零售商所出具，如商业银行出具的黄金定期储蓄存单、黄金汇票和黄金账户存折，上海黄金交易所出具的黄金提货单或黄金仓储单据，黄金企业发行的黄金债券等等。

纸黄金的英文表达是paper gold。

Paper gold is a kind of asset that represents the price of gold but isn’t truly gold; it’s not backed by real metal, thus it’s just worth paper. Holding paper gold allows you to acquire exposure to the price of gold without having to own real bullion, and it’s more beneficial for trading than long-term investing. Gold certificates, pool accounts, gold futures accounts, and most exchange-traded funds are examples of paper gold.

由此，纸黄金交易的英文表达可以是paper gold trading。

具体可参考如下双语例句：

除纸黄金交易时的实际买入或卖出价外，本行并不收取手续费。

There are no handling charges of the Bank other than the actual buying or selling price at the time of transaction of paper gold.

投资决定是由阁下自行作出的，但阁下不应开立「户口」及投资在纸黄金，除非中介人于销售有关产品时已向阁下解释经考虑阁下的财务情况、投资经验及目标后，有关产品是适合阁下的。

The investment decision is yours but you should not open the Accounts and invest in paper gold unless the intermediary who sells it to you has explained to you that the relevant product is suitable for you having regard to your financial situation, investment experience and investment objectives.
