问一道题：NO.PZ2018091706000058 [ CFA II ]

NO.PZ2018091706000058 问题如下 The following are the current spot rate anforwaroints being quotefor theCHF/Gcurrenpair:The current all-inbirate for livery of Gagainst the CHF in three months isclosest to: 1.49136 B.1.49150 C.1.49164 Thecurrent all-in three month birate for G(the base currency) is equalto1.4939 + (–25.4/10,000) = 1.49136.解析根据表格数据，计算过程如下1.4939+ (–25.4/10,000) = 1.49136. 三个月后，CHF/GBP，1.49136~1.4889.4，为什么会出现ask price比biprice小的情况？这在现实中可能出现吗？
