"... we have applied text analysis methodologies to extract information from descriptions in the OpRisk database. After delicate tasks like data cleaning, text vectorization, and semantic adjustment, we apply methods of dimensionality reduction and several clustering models and algorithms to develop a comparison of their performances and weaknesses. Our results improve retrospective knowledge of loss events and enable to mitigate future risks."
"... operational risk remained the most prominent major risk type after the outbreak of Covid-19, and that disclosures of operational risk increased by 5.19% compared with the samples from before the outbreak. The drivers of operational risk also changed, with significant increases in disclosure of litigation risk, transaction modes and product and service problems as a proportion of total disclosures. In addition, two emerging operational risk drivers identified during the pandemic are data safeguarding and goodwill impairment."
"... our empirical evidence indicates that political risk significantly a firm’s operational risk strategy in terms of managing its customer concentration risk."
"We use firm-day level data from RepRisk about negative operational incidents that are classified into environmental, social, and/or governance issues. We find that analyst outputs predict negative ESG incidents, suggesting that analyst outputs contain information that is predictive of these events."
"Our findings offer new evidence on how economic shocks transmit to banking industry losses with implications for risk management and supervision."
"This paper considers the question from a non-technical point of view and surveys the regulatory requirements for capital adequacy contained in the so-called Basel framework. It analyses all contributing parts of the Capital Adequacy Ratio (CAR), including regulatory capital, credit risk, market risk and operational risk, raising in each case the concerns of the literature as well as recent contributions."
"Evidence that the COVID-19 pandemic had minimal effect on operational risk losses in 2020 is presented and the effect of model risk is emphasized. Our results show that the existence or otherwise of significant correlations depends on the regression model used, whether data series show trends, the time window concerned, geographical location and the type of financial institution."
"... climate change may drive operational risk losses through complex interactions between three factors: changes in human and institutional behaviors, significant and rapid changes in economic metrics and direct physical impacts."
"... some operational risk managers are working more closely with their human resources partners to develop a more cohesive approach to people risk management. In the context of current reforms to the capital requirements for operational risk"
"... we find the difference in decision-makers’ probability assessments between operational and non-operational risk factors is greater when assessing a proximate rather than a remote target. We contribute to the accounting literature by demonstrating how spatial distance affects probability judgments."
