论文摘要
我们介绍了SABR模型的自然扩展,以在后透明世界中向后和前瞻性的RFR Caplet定价。可以使用Hagan等人的市场标准近似值来定价前瞻性RFR胶囊。 (2002)。我们提供封闭形式的有效SABR参数,用于向后看起来的RFR胶囊。这些结果对于微笑插值和分析归一化设备中的向后和前瞻性微笑很有用。
We present a natural extension of the SABR model to price both backward and forward-looking RFR caplets in a post-Libor world. Forward-looking RFR caplets can be priced using the market standard approximations of Hagan et al. (2002). We provide closed-form effective SABR parameters for pricing backward-looking RFR caplets. These results are useful for smile interpolation and for analyzing backward and forward-looking smiles in normalized units.
