贷款定价模型的应用研究

Research on The Application of Loan Pricing Model

本文探讨贷款利率基本模型的应用问题。在应用场景中发现,以往对基本模型的应用相当于假定贷款前公司负债为零,由此得出的贷款利率偏低。基于现实中公司负债率增量变化的情况应用模型,并考虑银行业务的经营成本,即可解决这个问题。进一步,基本模型还存在贷款利率与期限负相关的情况,基于实际应用场景分析,发现这其实是该模型的优点而非缺点,即贷款与否、贷款规模、贷款利率可以借助该模型得以解决。在此基础上,进一步探讨并解答了基本模型应用中负债率参数确定的细节问题。

This paper discusses the application of the basic model of loan interest rate. In the application scenario, it is found that the previous application of the basic model is equivalent to assuming that the company’s liabilities before the loan are zero, and the resulting loan interest rate is low. Based on the incremental change of corporate debt in reality, this problem can be solved by applying the model and considering in addition the operating cost of banking business. Furthermore, there is a negative correlation between loan interest rate and time to maturity in the basic model. Based on the analysis of application scenarios, it is found that this is actually the advantages rather than disadvantages of the model. Rely on this advantage, whether the loan is granted or not, the loan scale and the loan interest rate can be completely solved with the help of the model. On this basis, the details of determining the debt ratio parameters in the application of the basic model are further discussed and solved.
