Study On The Bank Lending Pricing From The Perspective Of Supply Chain Finance

Approved by the State Council,since July 20,2013,the central bank has fully liberalized the lending rate control of financial institutions,canceled the lower limit of 0.7 times the loan interest rate of financial institutions,and independently established the loan interest rate level by financial institutions according to the principles of business.The implementation of this policy marks the acceleration of China's interest rate marketization process and entering a critical stage.Therefore,under the background of interest rate marketization,the loan interest rate will become an important index of bank risk control after the pledge rate.Under the financial background of supply chain,this paper studies the downstream retailers in the supply chain under capital constraints that need to apply to the bank to apply for loans.Based on the bank,the paper studies the problem of determining the optimal loan rate for the commercial banks to provide loans to the downstream sellers.Based on the traditional newsvendor model,respectively,with the mean variance model and prospect theory to construct the risk aversion and loss aversion optimization model of banks,by solving the optimization model,the optimal analysis to obtain bank loan interest rate solution,and the optimal interest rate sensitivity analysis is carried out.This paper assumes that the capital market is completely competitive,and the bank opens a closed account for the retailer.One supplier and one retailer only exists in the supply chain,and retailers selling products are perishable goods,the supplier allows retailers to have two ordering opportunities,two order not only reduces the retailer's sales risk,and increase the yield and improve the supplier,the supplier's profit.The conclusions are as follows: first,the risk aversion type bank loan interest rate(bank long-term optimal loan interest rate)is not higher than the loss aversion bank loan interest rate(bank short-term optimal loan interest rate).Second,for risk averse banks,the greater the amount of the retailer's loan,the lower the bank loan interest rate and the higher the retail price.The higher the bank loan interest rate;the higher the bank risk aversion coefficient,the lower the bank loan interest rate;third,the higher the retail price,the higher the retail price for the loss evading banks,the higher the loan amount,the lower the bank loan interest rate.Through the comparison and analysis of the second and third conclusions,we can see that the retailer loan amount is negatively related to the bank loan interest rate,and has nothing to do with the type of risk preference of the bank.Thus,it can be seen that the qualitative relationship between the retailer loan amount and the bank loan interest rate has certain universal significance.Therefore,banks can regulate the loan interest rate of banks as an important risk control index according to the size of retailers' loans.Similarly,the retailer price is positively related to the bank lending rate and has nothing to do with the type of bank risk preference.Banks can also refer to the size of the retail price to decide how much interest rates they can lend to retailers.To sum up,the research content of this paper not only helps to solve the financing problem of small and medium enterprises in supply chain,but also has certain guiding significance to the risk of bank prevention and control loan.
