2021-02-24 11:08這是原版書(shū)中的一段話(huà),對(duì)于通脹在預(yù)期內(nèi)和超出預(yù)期,對(duì)債券產(chǎn)品的影響,但是不是很理解,希望老師解釋下:Because the cash flows are fixed in nominal terms, the effect of inflation is transmitted solely through the discount rates (i.e., the yield curve). Rising (falling) inflation induces capital losses (gains) as the expected inflation component of yields rises (falls). If inflation remains within the expected cyclical range, shorter-term yields rise/fall more than longer yields but have less price impact as a result of shorter duration. If, however, inflation moves out of the expected range, longer-term yields may rise/fall more sharply as investors reassess the likelihood of a change in the long-run average level of inflation. Persistent deflation benefits the highest-quality bonds because it increases the purchasing power of the cash flows, but it is likely to impair the creditworthiness of lower-quality debt. (1)為什么通脹在預(yù)期內(nèi),收益率曲線(xiàn)更平坦,超出預(yù)期,收益率曲線(xiàn)更陡峭? (2)通脹在預(yù)期內(nèi),資本利得的損失會(huì)減少? (3)通脹如果超出預(yù)期,為什么長(zhǎng)期的收益率波動(dòng)更大? 謝謝老師

同學(xué)你好:
1)如果通脹上升的的幅度在預(yù)期的周期波動(dòng)范圍內(nèi),那么短期的利率會(huì)快速反應(yīng)這一變化,但因?yàn)殚L(zhǎng)期的通脹預(yù)期比較穩(wěn)定,因此長(zhǎng)端利率上行的比短期的少,因此收益率曲線(xiàn)相對(duì)之前變平坦了;但如果上升幅度超過(guò)預(yù)期的范圍,那么大家對(duì)長(zhǎng)期通脹的預(yù)期也會(huì)調(diào)升,使得長(zhǎng)端的利率也款速上行,甚至比短期升更快。這也回答了第三個(gè)問(wèn)題,3)為什么如果通脹超預(yù)期,長(zhǎng)端收益率變動(dòng)幅度比較大,因?yàn)殚L(zhǎng)期通脹預(yù)期發(fā)生改變了。
,
2)通脹上行如果在預(yù)期內(nèi),那短期利率上行比長(zhǎng)端多,但短期利率久期短,對(duì)債券價(jià)格影響不大。而如果通脹超預(yù)期上升,長(zhǎng)端利率上行較多。長(zhǎng)端利率久期大,價(jià)格會(huì)因此下降更多。因此,通脹超預(yù)期上行對(duì)債券的價(jià)格的不利影響更大。
