2 Population Aging: A Human Triumph

By Joseph Chamie

Population aging is a triumph of civilization. It is the inevitable consequence of attaining desired smaller family sizes, lower mortality rates and longer lives, with many living beyond 100 years.

第四章 远期外汇交易

交叉汇率的套算 规则

（1）若报价方报出的两个即期汇率都是以美元为基准货币或者都是以美元为计价货币，则采用交叉相除的方法进行套算； （2）若报价方报出的两个即期汇率一个是以美元为基准货币另一个是以美元为计价货币，则采用同边相乘的方法进行套算。

【例1】已知：某日巴黎外汇市场报价

USD/CHF＝1.0110/20 ① USD/HKD=7.7930/40 ② 求：CHF /HKD

解：USD/ CHF＝1.0110/20， USD/HKD=7.7930/40

卖出1瑞郎（买入A美元）——卖出A美元（买入X港元） 1/ 1.0110×7.7940 ≈7.7092瑞郎对港元的卖出价

买入1瑞郎（卖出A美元） ——买入A美元（卖出X港元） 1/ 1.0120×7.7930 ≈7.7006瑞郎对港元的买入价 所以汇价：CHF /HKD＝7.7006/92

或解：(分析：两个报价都是以美元为基准货币，故采用交叉相除的方法。又因为CHF /HKD＝USD/HKD÷ USD/ CHF，故用②式(交叉)除以①式。)
