外汇升值2.68%,相当于本币贬值多少?

NO.PZ2018111501000001

问题如下:

Aron wants to analyze the movement of EUR against the foreign currency USD for portfolio X. It is known that the domestic-currency return is 15% and the foreign-currency asset return is 12%. Which of the following is correct?

选项:

A.

the percentage movement in the spot exchange rate is -2.61%, EUR relative to USD is appreciated.

B.

the percentage movement in the spot exchange rate is 2.68%, EUR relative to USD is appreciated.

C.

the percentage movement in the spot exchange rate is 2.68%, EUR relative to USD is depreciated.

解释:

C is correct.

考点:Currency Risk & Portfolio Return and Risk

解析:

RDC=(1+RFC)(1+RFX)1R_{DC}=(1+R_{FC})(1+R_{FX})-1

已知domestic-currency return is 15%,即RDC=15%R_{DC}=15\%,foreign-currency asset return is 12%,即RFC=12%R_{FC}=12\% ,代入公式,则RFX=2.68%R_{FX}=2.68\% 。根据EUR/USD(DC/FC)的外汇报价方式,由于RFX>0R_{FX}>0,因此USD相对于EUR是升值的,也就是说, EUR相对于USD是贬值的。

问题1.这道题目 本币EUR, 外币是USD 对吗? 题干中 ,如果说 foreign currency USD,那么 USD 就是 外币吧?

(因为 总是习惯性 认为 USD是本币了)


问题2.这里算出来 Rfx ,外汇变动收益为2.68%


代表 外汇USD 相对于 EUR 上涨了2.68%


但是如果算,本币EUR 相对于 外汇下跌了多少%?怎么算呢?


USD/EUR 从1 ,变成 1.0268


EUR/USD从1,变成1/1.0268


则USD 变动幅度是 (1/1.0268-1)=-2.61%


是这样计算吗?

嗨,从没放弃的小努力你好:


同学你好

1.     问题1.这道题目 本币EUR, 外币是USD 对吗? 题干中 ,如果说 foreign currency USD,那么 USD 就是 外币吧?(因为 总是习惯性 认为 USD是本币了)

是的。本币是欧元,外币是美元,因为题干说了…the foreign currency USD…

2.     现在是外币美元升值了2.68%

也就是EUR/USD相当于由1涨到了1.0268;

对应的就是本币欧元贬值,即由1贬值到了1/1.0268.

因此计算欧元的贬值幅度是(1/1.0268-1)/ 1 = -2.61%

(同学最后的计算没有问题,前面表述中的汇率表达形式有问题,参考我上面写的)

NO.PZ2018111501000001 the percentage movement in the spot exchange rate is 2.68%,, EUR relative to USis preciate这个答案没问题,但是我们在计算 spot exchange rate是不是应该站在EUR角度,这样计算数值应该是-2.61%,毕竟题目问的是analyze the movement of EUR against the foreign currenUS
