摘要: 确定合适的质押商品贷款价值比率能够使银行有效缓释库存商品融资业务的信用风险。沿着简化式思路,本文假定借款企业违约事件外生并服从重随机泊松过程,建立了一个有关贷款价值比率的模型。在模型中,本文综合考虑了银行的风险偏好,质押商品的预期收益率和价格波动率,贷款周期和盯市频率等因素的影响,为银行在保持风险容忍水平一致的情况下确定特定库存商品融资业务的相应贷款价值比率提供了科学依据。

Abstract: Determining appropriate loan-to-value ratios of commodity collateral can make banks mitigate credit risk of inventory financing effectively.Based on reduced-form approaches,this paper assumes that the default of the enterprise is exogenous and follows a doubly stochastic Poisson process,and then provides a modelon loan-to-value ratios.In this model,some factors,such as risk appetite of banks,expected rate of return and price volatility of commodity collateral,frequency of marking to market and maturity time of loan,are considered synthetically,so banks may determine appropriate loan-to-value ratios of particular inventory financing operation to keep the level of taken risk consistent.

Key words: inventory financing, loan-to-value ratios, commodity collateral, credit risk
