本文简单介绍了中国利率市场化改革进程和当前的利率市场化状况,并以贷款利率放开、存款利率管制为前提,构建了一个简单的利率市场化模型。模型暗示,假定银行信贷需求和信贷结构不变,管制放开将带来银行存款利率的上升、存款数量的增长、贷款利率的下降以及银行利差的收窄。以对保本理财市场和大额协存市场利率数据的观察为基础,并考虑货币基金发展对银行资金成本的影响,本文粗略估计,利率市场化也许使银行利差收窄100BP左右。 This article briefly introduces the process of the marketization of interest rate liberalization in China and the current marketization of interest rates. A simple model of interest rate marketization is constructed on the premise of lending rate liberalization and deposit interest rate control. The model implies that given the constant credit demand and credit structure of banks, the liberalization of controls will result in an increase in bank deposit rates, an increase in the number of deposits, a drop in lending rates, and a narrowing of bank spreads. Based on the observation of the interest-rate data of the guaranteed capital market and the large-value syndication market and considering the influence of the development of the monetary fund on the capital cost of the bank, this article roughly estimates that the interest rate liberalization may narrow the bank spread by about 100 BP.
