Using 285 firm-year observations encompassing the period 2010–14 for risk governance indexes, we investigate the moderating effects of market competition, relative to total risk governance practices, on banks’ ORD quality. The results of our panel data analysis show that there is a substitution effect of competition, which could reduce the adverse consequences of weak risk governance practices. However, governance factors – such as the chief risk officer’s (CRO’s) role and independence, and the risk communication system – decrease voluntary ORD quality. These findings have implications for the role of the financial regulator in using market competition as an effective mechanism to replace banks’ weak risk governance, thus encouraging banks to improve their ORD quality. This study contributes to existing knowledge by providing new empirical insights into ongoing debates about the complementary or substitutionary role of competition policies and corporate governance practices.","PeriodicalId":54030,"journal":{"name":"Journal of Operational Risk","volume":"29 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87804649","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Maintaining a factor model structure allows us to easily derive the asset expected returns and their corresponding covariance matrix. By design, these two parameters are calibrated to better describe the properties of the different market regimes. In turn, these regime-dependent parameters serve as the inputs during mean–variance optimization, thereby constructing portfolios adapted to the current market environment. Through this formulation, the proposed model allows for the construction of large, realistic portfolios at no additional computational cost during optimization. Moreover, the viability of this model can be significantly improved by periodically rebalancing the portfolio, ensuring proper alignment between the estimated parameters and the transient market regimes. An out-of-sample computational experiment over a long investment horizon shows that the proposed regime-dependent portfolios are better aligned with the market environment, yielding a higher ex post rate of return and lower volatility than competing portfolios.","PeriodicalId":54030,"journal":{"name":"Journal of Operational Risk","volume":"43 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88056148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines the spillover effect of that cyber heist on the cyber risk disclosures of the banking sector in Bangladesh. Building on institutional theory, we propose that in emerging markets, after a notable cyber heist experienced by the country’s central bank, the banking sector of the country tends to increase cyber risk disclosures as an institutional strategy to regain legitimacy. Analyzing the disclosures in the annual reports of 38 commercial banks from 2014 to 2018, we find that banks’ cyber risk disclosures significantly increased after the BB cyber heist.We also find that the political embeddedness of the banks and their adherence to Islamic Shariah negatively influence a bank’s tendency to use cyber risk disclosures as a legitimacy-regaining strategy after the heist. Our institutional perspective offers new insights into why the banks in an emerging country engage more in cyber risk disclosures after such an atrocious cyber attack.","PeriodicalId":54030,"journal":{"name":"Journal of Operational Risk","volume":"64 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74098639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mocanu","doi":"10.21314/JOP.2020.248","DOIUrl":"https://doi.org/10.21314/JOP.2020.248","url":null,"abstract":"For banks, operational risk losses are likely to have a significant impact not only on their financial condition, but also on their reputation. This makes operational risk management (ORM) particularly important. In relation to ORM, the Basel Committee on Banking Supervision promotes a banking supervision policy based on the idea of “enforced self-regulation”. Thus, the central banks of different countries regulate ORM according to the specificities of their national banking industry. This paper tests the hypothesis that such regulatory openness results in legal texts that are highly influenced by the culture of the country in which each central bank issuing guidelines on ORM is located. The author analyzes a corpus of approximately 50 000 words that feature in ORM guidelines published in English by the central banks of China, Hong Kong, India, Indonesia, Japan, Singapore and South Korea. By applying the Kendall coefficient, the following significant correlations have been found: (a) the higher the masculinity dimension, the less clear the text; and (b) the higher the masculinity dimension, the less prescriptive the text. Moreover, our content analysis reveals that each operational risk-related item has a different weight in the guidelines of different countries. The research results should be useful to regulators looking to fine-tune their decisions in different cultural environments.","PeriodicalId":54030,"journal":{"name":"Journal of Operational Risk","volume":"87 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82386433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, we explore the joint effect of banking characteristics, corporate governance and credit rating on the informational content of operational risk disclosure (OpRiskDISC). We use content analysis to collect OpRiskDISC data from annual reports during the period 2008–15. The results for each bank type show that the enhanced OpRiskDISC in IBIs is negatively associated with the number of bank branches, the financial stability of the bank, board meeting frequency, the proportion of independent members and credit rating. The results for CBs demonstrate that a bank’s size and financial stability are positively associated with OpRiskDISC. Conversely, the OpRiskDISC level is negatively affected by board meeting frequency and the number of bank branches. For the overall sample, our empirical results show that bank size, compliance with Sharia requirements and board size have a positive, significant effect on OpRiskDISC, while the number of bank branches and the proportion of independent members on the board have a negative, significant relationship with the disclosure level.","PeriodicalId":54030,"journal":{"name":"Journal of Operational Risk","volume":"18 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2020-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86614768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
