2020-05-04 09:18書(shū)后習(xí)題冊(cè)P120 第23題 答案中說(shuō)到“but inter-market carry trades frequently do not, especially if the currency is not hedged”。但是筆記中提到,inter-market carry trade可能導(dǎo)致duration mismatch(如圖)。是說(shuō)這里的maturity mismatch和duration mismatch在定義上無(wú)法近似嗎?另外,關(guān)于這道題中的statement 2,正確答案認(rèn)為這句話(huà)是錯(cuò)誤的,其答案解析中說(shuō)道“In addition, if two curves are involved they need not have different slopes provided there is a difference in the level of yields between markets”就是說(shuō)斜率差異不是進(jìn)行inter-market carry trade的關(guān)鍵,收益率的差異才是。然而這句話(huà)與筆記上的“To explore differences in the slopes of the two yield curves rather than the differences in overall rate levels(如圖)”這句話(huà)看似有些矛盾啊。

同學(xué)你好
講義和筆記上的話(huà)是從原版書(shū)中提取出來(lái)的,難免會(huì)有斷章取義的情況。
筆記這這句話(huà)是出自這一段。是在討論如何對(duì)沖匯率風(fēng)險(xiǎn)的情況。
In order to eliminate currency exposure in an inter-market trade, the investor must, explicitly or implicitly, both borrow and lend in each currency. The essence of this trade is to exploit differences in the slopes of the two yield curves rather than the difference in overall rate levels. The idea, assuming normal, upward sloping yield curves, is to lend at the long end and borrow at the short end on the relatively steep curve, and to lend at the short end and borrow at the long end on the relatively flat curve.

我沒(méi)感覺(jué)出有啥斷章取義的問(wèn)題啊。。。我覺(jué)得提煉的挺準(zhǔn)的。。。所以我還是覺(jué)得您在回答中復(fù)制的書(shū)上這段話(huà)和這道題中答案的解析有些矛盾啊。。。

另外關(guān)于一開(kāi)始問(wèn)的maturity mismatch的問(wèn)題呢?答案中說(shuō)inter-market carry trade不會(huì)導(dǎo)致maturity mismatch,而圖中筆記的內(nèi)容說(shuō)inter-market carry trade會(huì)導(dǎo)致duration mismatch。此前我還有另外一個(gè)問(wèn)題中涉及到了duration/maturity mismatch的內(nèi)容,結(jié)合那部分您的回答,我現(xiàn)在感覺(jué)這兩個(gè)說(shuō)法是不矛盾的:也就是說(shuō),maturity mismatch如果不存在的話(huà),duration mismatch就很可能存在,因?yàn)閙aturity和duration本身從概念上到時(shí)間跨度的數(shù)值上都是不同的(除零息債外)。所以關(guān)于這個(gè)問(wèn)題您看我現(xiàn)在的理解是否正確?

同學(xué)你好
inter-market是軋兩個(gè)不同國(guó)家的收益率曲線的利差,所以可能是期限匹配的或者不匹配的,比如說(shuō)借5年JPY投5年BRL,或者借1年JPY,投5年BRL。所以maturity可以是match的也可能是不match的。這個(gè)書(shū)上有原話(huà)。
Inter-market carry trades, those involving more than one currency are more varied and complex. First, the trade depends on more than one yield curve. Second, the investor must either accept or somehow hedge currency risk. Third, there may or may not be a duration mismatch.
如果只討論carry trade這種交易本身,可能會(huì)讓duration match或不match,但放在組合管理的角度,我進(jìn)行主動(dòng)的收益率曲線策略時(shí),應(yīng)該保持duration -neutral,因?yàn)橥顿Y組合對(duì)主要的風(fēng)險(xiǎn)敞口是有觀點(diǎn)的,我想承擔(dān)多大的利率敞口是有規(guī)定的,所以組合的久期通常是不能隨便調(diào)整的。
另外maturity match不代表duration match,兩者是不是的概念,maturity只跟時(shí)間有關(guān),而duration會(huì)受到利率和現(xiàn)金流發(fā)生時(shí)點(diǎn)的影響。
也可能maturity match的時(shí)候,剛好duration也match,也可能duration不match。maturity match主要是跟carry trade借貸的時(shí)間有關(guān)。而duration match主要是跟組合整體的風(fēng)險(xiǎn)有關(guān)。 -
追問(wèn)
謝謝老師,關(guān)于maturity和duration match的問(wèn)題,我明白了。然后我們回到之前討論的問(wèn)題,就是這個(gè)inter-market carry trade的問(wèn)題(statement 2);我又看了一下,這個(gè)statement錯(cuò)其實(shí)是錯(cuò)在了,carry trade其實(shí)包括intra-/inter-market carry trade,其中后者又包含需要hedge和不需要hedge的情況,但是這三種carry trade中只有最后一種是需要兩國(guó)的收益率曲線斜率substantially different的。所以直接說(shuō)carry trade需要收益率曲線substantially different是不正確的。這個(gè)理解沒(méi)問(wèn)題吧?

同學(xué)你好
如果收益率曲線的斜率一樣,但其中一條的利率很高,另一條利率很低,也能軋出利差。
