问题如下:
3. Which of the following market developments would be most favorable for Subscriber 3's trading plan?
选项:
A.
A narrower interest rate differential.
B.
A higher forward premium for INR/USD.
C.
Higher volatility in INR/USD spot rate movements.
解释:
B is correct.
Subscriber 3's carry trade strategy is equivalent to trading the forward rate bias, based on the historical evidence that the forward rate is not the center of the distribution for the spot rate. Applying this bias involves buying currencies selling at a forward discount and selling currencies trading at a forward premium. So a higher forward premium on the lower yielding currency—the USD, the base currency in the INR/USD quote—would effectively reflect a more profitable trading opportunity. That is, a higher premium for buying or selling the USD forward is associated with a lower US interest rate compared to India. This would mean a wider interest rate differential in favor of Indian instruments, and hence potentially more carry trade profits.
A is incorrect because Subscriber 3's carry trade strategy depends on a wide interest rate differential between the high-yield country (India) and the low-yield country (the United States). The differential should be wide enough to compensate for the unhedged currency risk exposure.
C is incorrect because a guide to the carry trade‘s riskiness is the volatility of spot rates on the involved currencies, with rapid movements in exchange rates often associated with a panicked unwinding of carry trades. All things being equal, higher volatility is worse for carry trades.
中文解析:
B选项:higher forward premium或者表述为larger forward premium,是两国利差变大的意思,所以在carry trade中看到这个表述就直接等同为两国利差变大。
可以从下面这个角度来理解:
(1)我们可以用covered interest rate parity(抛补的利率平价公式)来解释,根据. covered interest rate parity:F/S0=(1+r_A)/(1+r_B) (汇率标价形式为A/B); 其中r_A (2)得到F (3)所以,如果F/S0=(1+r_A)/(1+r_B)这个公式中r_A 2. 执行carry trade的条件有二,一是两国利差大,二是汇率变化很小。因此A选项和C选项的表述是错误的
不对啊,专门讲过roll yield,这b选项不就导致roll yield是小于0么,那这样成本就变大了不是不利么
