【摘要】:在國(guó)際金融環(huán)境變化不斷加劇、全球化進(jìn)程不斷深入的背景下,如何管理好信用風(fēng)險(xiǎn)是各國(guó)家所面臨的重要問題。本文利用Merton結(jié)構(gòu)式模型思想,考察了抵押資產(chǎn)組合對(duì)信用風(fēng)險(xiǎn)的分散與緩釋作用,含有抵押資產(chǎn)組合的零息債券定價(jià)、信用違約和信用利差結(jié)構(gòu)問題。研究結(jié)果表明,抵押資產(chǎn)與標(biāo)的資產(chǎn)之間的相關(guān)性及波動(dòng)率都影響違約概率和信用利差期限結(jié)構(gòu);有抵押時(shí)違約概率要小于無抵押時(shí)的違約概率;存在抵押資產(chǎn)組合時(shí),零息債券的信用利差要小于無風(fēng)險(xiǎn)時(shí)的信用利差,抵押資產(chǎn)組合下的信用利差大于單一抵押資產(chǎn)下的信用利差;并且含有抵押資產(chǎn)組合的信用利差期限結(jié)構(gòu)形狀為L(zhǎng)型曲線。
[Abstract]:Under the background of the change of international financial environment and the deepening of globalization, how to manage credit risk well is an important problem that every country faces. Based on the idea of Merton structural model, this paper investigates the dispersion and slow release of credit risk caused by mortgage portfolio, the pricing of zero interest bond with mortgage asset portfolio, credit default and credit spread structure. The results show that the correlation and volatility between mortgage assets and underlying assets affect the default probability and the term structure of credit spreads, and the default probability of mortgage is smaller than that of unsecured assets. When there is a portfolio of mortgage assets, the credit spread of zero-interest bonds is smaller than that of risk-free bonds, and the credit spread under the portfolio of mortgage assets is larger than that under a single mortgage asset. And the term structure of credit spread with mortgage portfolio is L-shaped curve.
