Features: This book introduces certain innovations in theory. First, the Weibull distribution prepayment model proposed in the prepayment prediction model is a breakthrough against the currently commonly used Log-logistic model and exponential model. Second, in the pricing method, to address the flaw of the fixed yield rate used for discounting Treasury bonds in the commonly used static spread pricing method, the CIR Treasury bond pricing method is introduced to describe and analyze the random process of Treasury bond rates. Combining the pricing concept of coupon-bearing Treasury bonds, an extension is made, proposing the CIR mortgage-backed security pricing method and establishing a spread pricing model for mortgage-backed securities under the free market interest rate. Third, in differential equation pricing, the general method for derivative securities summarized by John C. Hull is applied to establish a differential equation pricing method for mortgage-backed securities under the free interest rate, opening up a new approach to establishing differential equations for mortgage-backed securities. At the end of the book, based on China's actual conditions, the author puts forward their own views on the operation and pricing of securitization in China.
