B.Matthew should buy GBP in the interbank market and sell it to the dealer.
C.Matthew should buy GBP in the dealer market and sell it to the interbank market.
解释:
B is correct.
考点:三角套汇的经典考法,考的是其中的第一步和第二步。
解析:第一步先判断有没有套利机会,也就是比较dealer 和 interbank相同币种的报价。这道题对比的是GBP那么在dealer市场报价MXN/GBP是 27.8995/28.0255 。然后在interbank市场计算MXN/GBP的报价,从表格可以看出我们需要把2个报价转换成MXN/GBP,那么根据口诀,相乘同边,相除对角,乘小除大,我们得到interbank市场的MXN/GBP的报价: 27.2377/27.6464 。由于两边市场的报价不一样(interbank市场报价明显),所以是有套利机会的。第二步就是具体操作了,我们从上述的步骤可以对比出interbank市场的报价要更加便宜,那我们就现在interbank市场买GBP,然后去dealer 市场上卖GBP,这样低买高卖就可以获得套利利润。
按题中MXN/GBP,我理解MXN是base currency,GBP是commodity currency,那么为何不是在interbank买入MXN,在dealer处卖出MXN来套利,而是变成在interbank买入GBP,在dealer处卖出GBP?谢谢啦(计算步骤都一致,最后一步判断我是以买MXN理解而非买GBP理解,所以反了)
