Global financial stress is a critical variable that reflects the ongoing state of several key macroeconomic indicators and financial markets. Predictive analytics of financial stress, nevertheless, has seen very little focus in literature as of now. Futuristic movements of stress in markets can be anticipated if the same can be predicted with a satisfactory level of precision. The current research resorts to two granular hybrid predictive frameworks to discover the inherent pattern of financial stress across several critical variables and geography. The predictive structure utilizes the Ensemble Empirical Mode Decomposition (EEMD) for granular time series decomposition. The Long Short-Term Memory Network (LSTM) and Facebook's Prophet algorithms are invoked on top of the decomposed components to scrupulously investigate the predictability of final stress variables regulated by the Office of Financial Research (OFR). A rigorous feature screening using the Boruta methodology has been utilized too. The findings of predictive exercises reveal that financial stress across assets and continents can be predicted accurately in short and long-run horizons even at the time of steep financial distress during the COVID-19 pandemic. The frameworks appear to be statistically significant at the expense of model interpretation. To resolve the issue, dedicated Explainable Artificial Intelligence (XAI) methods have been used to interpret the same. The immediate past information of financial stress indicators largely explains patterns in the long run, while short-run fluctuations can be tracked by closely monitoring several technical indicators.
全球金融压力是一个关键变量,反映了几个关键宏观经济指标和金融市场的当前状态。然而,截至目前,金融压力的预测分析在文献中很少受到关注。如果能够以令人满意的精度进行预测,那么市场压力的未来走势是可以预期的。当前的研究采用了两种精细的混合预测框架,以发现多个关键变量和地区的金融压力的内在模式。预测结构利用总体经验模态分解(EEMD)进行精细的时间序列分解。在分解后的组件之上调用长短期记忆网络(LSTM)和Facebook的Prophet算法,以严谨地研究由金融研究办公室(OFR)监管的最终压力变量的可预测性。还使用了基于Boruta方法的严格特征筛选。预测性分析的结果表明,即使在新冠疫情期间严重金融困境时期,资产和各大洲的金融压力在短期和长期范围内都可以准确预测。这些框架在牺牲模型解释性的情况下似乎具有统计学意义。为了解决这个问题,已经使用了专门的可解释人工智能(XAI)方法来进行解释。金融压力指标的近期信息在很大程度上解释了长期模式,而短期波动可以通过密切监测几个技术指标来跟踪。
