摘要: 利用自2009年7月至2016年6月我国银行间债券市场国债收益率数据对新旧券利差进行研究,结果显示5年期、7年期、10年期国债新旧券利差为负,且随着期限的增加,国债新旧券利差在统计上愈为显著,短期国债和中长期国债投资用途的差异是造成这一现象的主要原因。本文还提出基于状态空间模型的国债收益率分解方法,在不依赖代理变量的基础上对收益率中的潜在因子进行直接量化。

Abstract: Using the data of Treasury bonds yields to maturity(YTM) in China Interbank Bond Market from Jul 2009 to Jun 2016, this paper empirically shows that 3-year, 5-year, 7-year and 10-year on-/off-the-run yield spread are statistically negative and the yield spread becomes more significant as the terms of Treasury bonds get longer. This paper demonstrates that the result is mainly driven by the varying purposes of Treasury bonds with different terms. Additionally, a state-space model is developed to decompose Treasury bond TYM into latent factors and directly quantify them without any proxies.
Keywords: Treasury bonds; liquidity premia; on/off-the-run yield spread; state-space model
