从资产负债表机理看信用货币创造的内在逻辑

“存款创造贷款、贷款创造存款”是主流货币理论的重要基础。英国学者乔西·瑞安-柯林斯等人和中国学者孙国峰等人认为,“存款创造贷款”的原理存在根本性错误,用于存款的货币均为贷款的产物,因此,不是“存款创造贷款”而是“贷款创造存款”,银行可以无限地凭空创造贷款。本文对这一认识寻根溯源,指出其中的偏颇之处。“贷款创造存款”的认识,从麦克鲁德算起已有140多年的历史,但它并不符合信用货币创造和资产负债表复式记账的内在机理。商业银行贷款以有款可贷为前提;在无款可贷条件下,贷款合同只是一纸空文。在实施贷款行为中,资金应从商业银行在央行的存款账户划到客户在商业银行的存款账户。从资金流程角度看,这是“存款创造存款”过程。从央行资产负债表看,不论是“发行货币”还是收取“存准”、吸收超额存款准备金都是资金来源的重要渠道,有了资金来源,才能有效地开展贷款、贴现、公开市场操作等“资金使用”,这一切操作都建立在真实资金的基础上,并非无中生有的“贷款创造存款”。“存款创造贷款”与“贷款创造存款”之争在理论逻辑中无解,要解开这一死结,需要回到历史起点。人民币最初入市是与边币和旧币的兑换,初始信用货币并非来自贷款;银行券的问世建立在贵金属货币准备的基础上,并非来自贷款。如果银行可以凭空创造贷款,则不存在美国硅谷银行破产事件,也不存在2008年美国金融危机,同时,利率理论、商业银行经营管理理论、资产负债表理论、货币政策理论、汇率理论等均将失效。
