Research On The Hypothec Value Of Commercial Buildings Based On Credit Risk Model

Commercial banks are at the core of China's financial system and the key to ensuring the normal operation of the national economy.Because of its special business object for the currency,determines the commercial banks operating high debt and high risk.In the commercial banking business always runs through all kinds of risks,such as credit risk,policy risk,business risk,market risk.The potential and diffuse nature of these risks are likely to cause the risk of individual banking business gradually evolved into financial sector risks,and thus the formation of systemic risk,and eventually may lead to financial crisis,which illustrates the destructive nature of bank loan risk.After the Mexican financial crisis of 1990's and the Asian financial crisis,the US subprime mortgage crisis in 2007 triggered the global financial crisis in 2008,the governments and financial institutions strengthened the importance of preventing and defusing the risk of bank loans.Credit risk prevention and control,but also become the national financial sector regulators and relevant practitioners of common concern and in-depth study of the subject.By summarizing and summarizing the scholars' research on the root causes of the debt crisis,it can be found that one of the most widely cited factors is the unreasonable standard of mortgage loan.One of the most important reasons for the increase of NPLs and the increase of default risk is the blindness and irrationality of mortgage loans.This irrationality comes from the fact that the determination of the amount of mortgage loans is vulnerable to the impact of mortgage market.In order to give full play to the role of mortgage business in protecting the safety of bank funds and guarding against credit risk,the key point is to scientifically and reasonably estimate the value of mortgage assets.If we can make use of the value discovery of asset value assessment in mortgage business,analyze the influence of mortgage asset value on loan risk,forecast and control the default risk of loan,and then improve the valuation method of traditional mortga ge asset,and more reasonably determine Value of mortgage assets.This can not only enhance the bank's ability to resist risks,but also has a significant role in preventing and resolving the risk of bank loans.In this paper,the methods of document collation and induction,comparative analysis,indirect survey and field survey,quantitative analysis and so on.Based on the severe risk of the commercial banks in our country and the increase of non-performing loans,the paper puts forward the urgency and importance of risk control and dissolution in the mortgage business,and points out that credit risk is the most important part of all risks.The increase in credit risk is due in large part to inaccurate estimates of the value of the collateralized assets.The relationship between the value of collateral assets and the risk of loans is analyzed based on the credit risk measurement in the framework of Basel agreement II.The model is used to calculate the size of the credit risk measure under Basel agreement II and use this index as the parameter to calculate the mortgage value of commercial buildings.The traditional valuation method of mortgage assets is improved and the commercial value Housing market value to be amended.In the end,this paper analyzes the mortgage valuation of a business building in M City as an empirical analysis to verify the rationality and feasibility of the improved mortgage valuation method based on credit risk model.
