论文摘要
在金融危机之后,监督当局已大大改变了金融压力测试的运作方式。尽管做出了这些努力,但市场参与者就考虑到不切实际的方法论假设和简化而提出了重大关注和广泛的批评。当前的压力测试方法试图通过使用多种卫星模型来模拟金融机构资产负债表的基础风险。这使他们的集成一项非常具有挑战性的任务,导致重大估计错误。此外,仍然可以忽略可能捕获不良冲击的非线性性质的先进统计技术。这项工作旨在通过提出一种基于深度学习进步的新方法来解决这些批评和缺点,这是一种针对动态资产负债表压力测试的原则性方法。关于新收集的财务/监督数据集的实验结果,提供了有力的经验证据,表明我们的范式明显优于传统方法。因此,它能够更准确,有效地模拟现实世界的情况。
In the aftermath of the financial crisis, supervisory authorities have considerably altered the mode of operation of financial stress testing. Despite these efforts, significant concerns and extensive criticism have been raised by market participants regarding the considered unrealistic methodological assumptions and simplifications. Current stress testing methodologies attempt to simulate the risks underlying a financial institution's balance sheet by using several satellite models. This renders their integration a really challenging task, leading to significant estimation errors. Moreover, advanced statistical techniques that could potentially capture the non-linear nature of adverse shocks are still ignored. This work aims to address these criticisms and shortcomings by proposing a novel approach based on recent advances in Deep Learning towards a principled method for Dynamic Balance Sheet Stress Testing. Experimental results on a newly collected financial/supervisory dataset, provide strong empirical evidence that our paradigm significantly outperforms traditional approaches; thus, it is capable of more accurately and efficiently simulating real world scenarios.
