這是原版書中的一段話,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),收益率曲線更平坦,超出預(yù)期,收益率曲線更陡峭? (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,為什么長期的收益率波動(dòng)更大? 謝謝老師
