解释:利率连续为什么就影响期货价格?那对于远期合约呢?课上没有讲这个吧

同学你好,关于这个问题考察的知识点在R57的Futures Pricing and Valuation中专门进行了讲解,同学可以再去听一下这个视频哦。
这道题目问的是当利率是一个常数,期货和远期的价格大小是怎样的。利率是一个常数,说明利率大小和标的物的市场价格之间的相关系数为0,此时long position赚钱亏钱跟利率没有什么太大的关系,早拿到钱和晚拿到钱是没有什么差别的,所以此时两者的价格是相等的。当它们之间的相关系数为positive时,代表利率会随着标的物的市场价格的上涨而上涨,此时long position赚钱,如果提前拿到现金流,就可以再投资出去,因为利率上升的情况下再投资的机会更好,只有期货是可以提前拿到这个现金流的,所以此时期货的价格会高于远期的价格。反之,当它们之间的相关系数为negative时,代表利率会随着标的物的市场价格的上涨而下跌,此时long position赚钱,但是利率下跌再投资的机会不是很好,所以不希望提前拿到现金流,更希望晚拿到这笔钱,所以此时远期合约的价格会高于期货。

利率是常数时,早拿到钱不还是能获得投资收益吗,不应该期货价格高于远期合约价格吗
,在利率一致的情况下,期货是标准化合约接受程度和认可度更高,价格应当高于远期合约,不是吗?
