银行违约预测中的网络银行传染

Using Network Interbank Contagion in Bank Default Prediction

Riccardo Doyle

摘要:

理论上,银行间传染会加剧金融体系的损失,并在经济低迷时期导致更多的级联违约。在本文中,我们使用回归和神经网络模型进行违约分析,以验证银行间传染是否对违约事件提供任何预测解释力。我们使用前四个季度的数据预测2010年第一季度美国上市商业银行的违约情况。一些既定的预测指标(如一级资本比率和股本回报率)与传染病一起被纳入,以衡量后者是否增加了重要性。基于这种方法,我们得出结论,银行间传染是非常解释性的违约预测,往往优于更既定的指标,在回归和神经网络模型。这些发现对未来使用银行间传染作为压力测试的一个变量,银行发行的债券估值和更广泛的银行违约预测具有相当大的影响。

英文摘要:

Interbank contagion can theoretically exacerbate losses in a financial system and lead to additional cascade defaults during downturn. In this paper we produce default analysis using both regression and neural network models to verify whether interbank contagion offers any predictive explanatory power on default events. We predict defaults of U.S. domiciled commercial banks in the first quarter of 2010 using data from the preceding four quarters. A number of established predictors (such as Tier 1 Capital Ratio and Return on Equity) are included alongside contagion to gauge if the latter adds significance. Based on this methodology, we conclude that interbank contagion is extremely explanatory in default prediction, often outperforming more established metrics, in both regression and neural network models. These findings have sizeable implications for the future use of interbank contagion as a variable of interest for stress testing, bank issued bond valuation and wider bank default prediction.
