Nelson-Siegel模型在國債定價和績效分解中的應用
[Abstract]:The term structure of interest rate is a core theme for both macro-economy and micro-finance, which directly and comprehensively reflects the price of funds with different maturity in the market. The term structure of the interest rate of national debt reveals the information of interest rate fluctuation in a country's financial market, which plays an important reference role in the implementation of monetary policy and the guidance of financial investment. Taking Nelson-Siegel model as the main line, this paper systematically analyzes the characteristics of the model and its rich economic meaning, and expounds its application to the construction, prediction of interest rate term structure and the decomposition of performance attribution compared with other common models in China. In the study, some useful conclusions are drawn. Nelson-Siegel model is more suitable for constructing our term structure of interest rate. By fixing 位 value of 1 and selecting the initial value of iteration effectively, the number of iterations is reduced. It meets the demand of real time interest rate term structure construction, improves the efficiency of pricing, helps investors to grasp the arbitrage opportunity and adjust the portfolio strategy, and makes a good foundation for the real transaction of treasury bond futures. The Nelson-Siegel (1) model can be used to predict the term structure of interest rate effectively by the method of predicting the parameters of the Nelson-Siegel model. The prediction results of the model are better than those of the model, and the short-term forecasting ability of the model is stronger than that of the model in the long term. In the practical application of fixed income bond income decomposition, this paper applies the decomposition method of Nelson-Siegel model parameters to the change of yield, which fills the blank in the application of domestic Nelson-Siegel model parameters, and is a bold and transcendental attempt. It has a strong guiding function to the attribution analysis of investment performance in financial circles. From the perspective of practice, this paper tries to put forward a framework: to find a method suitable for the construction of precise term structure of interest rate in China, and to find a reasonable way to predict and apply the term structure of interest rate. In this framework, the use of inter-bank bond data for empirical research in order to get a more practical application.
