求助,本题不是将spot rate and 6 months forward rate进行对比从而得出结论么

NO.PZ2018111501000021

问题如下:

Fundo do Brasil (FB) is a Brazilian sovereign wealth fund. FB has long equity positions in Australian and Swiss equities. Spot and forward market currency information for AUD and CHF is provided in Exhibit 1. FB managers have asked Campos for advice on whether it would be appropriate to hedge the currency exposure with forward contracts in AUD and CHF. Campos indicates she will examine the use of forward contracts to hedge currency exposure.

Based on the information provided in Exhibit 1, the most appropriate risk neutral strategy is for FB to:

选项:

A.

under-hedge AUD and over-hedge CHF.

B.

over-hedge AUD and not hedge CHF.

C.

under-hedge CHF and not hedge AUD.

解释:

B is correct.

考点:Tools of Currency Management: Forward

解析:用forward contracts对冲外汇风险,对冲的是卖AUDCHF的外汇风险,所以将来是short AUD forward, short CHF forward。相比预测的未来6个月的汇率(即不用合约锁定的汇率),2.1523>2.0355,所以应当hedge AUD,锁定更高的卖AUD的价格。并且over-hedge可以带来更高的收益。对于BRL/CHF2.4641<2.5642, 所以不hedge时,卖CHF的价格更高。

如题,根据基础班讲义第82页,本题为什么不选择A呢,when we compare spot rate with 6 months forward rate which reflects market opinion, AUD is likely appreciate, so the currency exposure might be underhedged. meanwhile CHK is likely depreciate, so the currency exposure might be over headged?

嗨,爱思考的PZer你好:


@cherry

同学你好

1.     首先呢,本题汇总AUD是预测贬值的,CHF是预测升值的。根据表格这种第二列和第四列来得到这个信息。因为第四列是预测的6个月后的即期汇率。

2.     判断是否要进行hedge是对比第三列和第四列的数据,即对比6个月的远期汇率和预测的6个月后的即期汇率,注意不是当前的即期汇率。

因为远期合约锁定的是将来6个月后的汇率,如果签订这个远期合约,意味着6个月后会以这个汇率来转换币种。所以他必须和预测的6个月后的市场上的即期汇率比较才有意义,和当前的汇率比较是没有意义的哈,因为时间点都不一样的。

嗨,努力学习的PZer你好:


同学你好~

1.     我们先来解释一下本题哈

本题本币是BRL,外币资产是AUD和CHF。用forward contracts对冲外汇风险,对冲的是卖AUD和CHF的外汇风险,所以将来是short AUD forward, short CHF forward。相比预测的未来6个月的汇率(即不用合约锁定的汇率,对应表格最后一列),2.1523>2.0355,所以应当hedge AUD,锁定更高的卖AUD的价格。并且over-hedge可以带来更高的收益。

对于BRL/CHF, 2.4641<2.5642(预测的汇率,表格最后一列), 所以不hedge时,卖CHF的价格更高。

2.     讲义82页的内容

(1)咱们一起看哈,他说预测GBP会贬值,所以需要over-hedge,这正好对应咱们本题中的AUD头寸呀,AUD也是也测会贬值的,所以我们要over-hedg;

(2)然后讲义又说如果预测会升值,就降低hedge的比率,就under-hedge。这又是对应本题中的CHF的头寸,预测会升值,然后我们就under-hedge,或者干脆就不hedge了。(下面是讲义82页的内容哈)

3. 最后向同学表达一下抱歉。

我这边负责衍生的答疑哈,这道题目也是衍生的内容。因为这道题目标签贴的是AA这门课,所以我刚刚才看到你的问题,就第一时间回复啦,希望没有耽误到同学的学习,加油~~

AUD预测不是升值吗?

cherry · 2022年02月09日

为什么不用即期汇率比较,而是用6个月后的即期汇率呢?
