目前,国内几家大银行在部分大中城市开办了个人外汇买卖业务(俗称炒汇),为广大的个人外汇持有者增加了一个新的投资渠道。特别是国家近期全面提高美元等四种外币的存储利率后,个人外汇买卖市场交易量明显攀升。通过外汇买卖可以规避汇率变动造成的损失,或选择高利率的币种增加利息收入,当然也具有一定的风险。那么,参与外汇买掌握基本的金融知识对自己所持有的外币未来走势的正确判断,是买卖外汇获利的基本前提。这要求炒汇者对全球外汇市场的基本情况以及影响汇价变动的基本因素要有所了解。同其他形式的买卖交易大致相同,供求关系在很大程度上决定了外汇买卖的价格。影响国际外汇市场供求关系的主要因素有:1.基本的经济、金融因素;2.政治与传媒因素3.各国中央银行的政策因 At present, several major domestic banks have opened up personal foreign exchange trading (commonly known as “speculative exchange”) in some large and medium-sized cities, adding a new investment channel to a large number of individual foreign exchange holders. In particular, the country recently comprehensively increased storage rates of four foreign currencies such as the U.S. dollar.
