补充资料:上海规元
1856年(咸丰六年)起,通行于上海的一种作为记帐单位的虚银名目。又称九八规元。上海开埠前,贸易上已有以九八规元为标准的计算方法。所谓九八规元,即以元宝(实银)的重量,加以升水,再以九八除之,所得之数即为上海通用的标准银(虚银)。开埠后,这种计算方法在租界内的华商之间依然沿用,但外商与华商之间的交易则以在中国流行的西班牙银币──本洋为记帐单位。到了1856年,本洋来源越来越少,几至绝迹,市价日益昂腾,贸易双方实际支付本洋时的困难无法解决,经过剧烈争议,外商也不得不接受这种九八规元代替本洋为记帐单位。此后,不论华洋交易及汇兑行市,均以此为计算标准。随着上海日益成为全国商业、贸易中心,这种九八规元,不仅是上海普遍应用的记帐单位,也为全国商界所熟知和应用,买卖上海规元已成为各地调剂金融、进行汇划调拨的一种手段(见银锭)。
用虚银为记帐单位,可以解决流通中使用实银一时供应不足和搬运不便等困难,但也使已经混杂的货币制度更增添了复杂性。1933年废两改元,上海规元亦停止使用。
