2020-11-03 13:33老師好,請(qǐng)問(wèn)FRA的期權(quán)定價(jià)為什么是把利率從t=4時(shí)點(diǎn)折現(xiàn)到t=0?而不是從t=1時(shí)點(diǎn)往前折現(xiàn)到0時(shí)刻?這個(gè)我反復(fù)聽(tīng)紀(jì)慧誠(chéng)老師的基礎(chǔ)課,我是真的搞不懂……

同學(xué)你好!
FRA是1時(shí)點(diǎn)知道1-4這段時(shí)間的借款利率,在4時(shí)點(diǎn)才真正支付利率,有現(xiàn)金流。因此折現(xiàn)是從4時(shí)點(diǎn)開(kāi)始。
致正在努力的你,望能解答你的疑惑~
如此次答疑能更好地幫助你理解該知識(shí)點(diǎn),煩請(qǐng)【點(diǎn)贊】。你的反饋是我們進(jìn)步的動(dòng)力,祝你順利通過(guò)考試~

FRA里面說(shuō)的不是1這個(gè)時(shí)間點(diǎn)就settlement了嗎?settlement也是在1這個(gè)時(shí)間點(diǎn)進(jìn)行的。1這個(gè)時(shí)間點(diǎn)borrow ,現(xiàn)金流入;4這個(gè)時(shí)間點(diǎn)return本息 現(xiàn)金流出。

同學(xué)你好!
是4時(shí)點(diǎn)settle,看一下原版書(shū)的原話,336頁(yè)。
In an FRA, the term “advanced” refers to the fact that the interest rate is set at Time h, the FRA expiration date, which is the time the underlying deposit starts. The term settled in arrears is used when the interest payment is made at Time h + m, the maturity of the underlying instrument. Thus, an FRA with advanced set, settled in arrears works the same way as a typical bank deposit as described in the previous example. -

這講義里講的是在到期日就settle啊……所以可以這么理解么,只是現(xiàn)實(shí)世界是到期日利息netting?

同學(xué)你好!
不好意思,我仔細(xì)查了下原版書(shū),以這個(gè)回答為準(zhǔn)。
FRA基本都是Advanced set, advanced settled,少數(shù)是Advanced set, settled in arrears。
Advanced set, advanced settled:
比如6x9FRA,9時(shí)點(diǎn)虛擬現(xiàn)金流1million,估值是9時(shí)點(diǎn)現(xiàn)金流折現(xiàn),6時(shí)點(diǎn)交割1million/(1+rf*3/12);
Advanced set, settled in arrears:
比如6x9FRA,9時(shí)點(diǎn)虛擬現(xiàn)金流1million,估值是9時(shí)點(diǎn)現(xiàn)金流折現(xiàn),9時(shí)點(diǎn)交割1million。
