The banking crisis started in March 2023 was triggered by disproportion of deposit liability and assets. Applying balance sheets from 1999 to 2022, from the Japanese Bank Association, this study scrutinizes the durability of high-priority banking systems against damaging events in that industry. Eyeing the unique high-level savings in Japanese banking, this study investigates the impact of disproportion of deposit liability and assets on the financial stability of interbank credit networks through a linkage-leverage analysis. This study presents a novel framework that combines actor-network theory, network optimization, and bilateral risk exposure approaches into linkage-leverage analysis. The results in this study show that the bilateral risk exposure during a subset of years is smaller than other years, which indicates that Japanese banks minimize the risk exposure by shifting the network relationship. Finally, this study provides supporting evidence to the new paradigms on developing more stable financial systems.

使用联动杠杆分析评估银行间信贷网络对系统性风险的抵御能力：来自日本的证据


2023年3月开始的银行业危机是由存款负债与资产失衡引发的。这项研究采用日本银行协会 1999 年至 2022 年的资产负债表，仔细审查了高优先级银行系统针对该行业破坏性事件的耐久性。本研究着眼于日本银行业特有的高水平储蓄，通过联动杠杆分析探讨存款负债与资产比例失调对银行间信用网络金融稳定性的影响。本研究提出了一个新颖的框架，将参与者网络理论、网络优化和双边风险暴露方法结合到联动杠杆分析中。本研究的结果表明，部分年份的双边风险暴露小于其他年份，这表明日本银行通过改变网络关系来最小化风险暴露。最后，本研究为发展更稳定的金融体系的新范式提供了支持证据。
