问题如下:
If futures prices are positively correlated with interest rates, the futures prices will be:
选项:
A.equal to forward prices.
B.higher than forward prices.
C.lower than forward prices.
解释:
B is correct. Futures contracts are more desirable than forwards for long positions when futures prices are positively correlated with interest rates. Futures payoffs occur everyday, whereas forward payoff occur all at expiration. When futures prices increase, the long positions have gains, they can reinvest the gains at higher interest rates.
中文解析:
期货有盯市制度,每日结算盈亏,而forward合约只能到期结算
以long 方为例,当期货价格与利率正相关的时候,当利率上升时,期货价格也上升,此时期货合约由于每日结算,因此可提前拿到利润,然后以一个更高的利息进行在投资;但远期合约不行,远期合约只能在期末拿到利润。相当于远期合约的利润只能以期初定价的无风险收益去投资,而期货合约却可以以一个更高的利率去投资;
所以期货要比远期合约更有优势,期货的价格也就高于远期的价格。
如果利率下降,Futures依然大于Forward的价值吗?
另外,一直有个问题没搞懂,Futures是每日结算,虽然Futures涨了可以提前拿到钱存银行,比Forward爽,但如果跌了,还要额外提前交保证金,损失了保证金存银行的利息,综合下来为什么就比Forward好呢?
