Purpose

This study aims to examine the effect of risk disclosure (RD) on commercial banks’ credit rating (CR) in the context of Bangladesh. It also explores the factors influencing RD in both Islamic and conventional banks.

Design/methodology/approach

The sample includes 200 bank-year observations consisting of 20 commercial banks (15 conventional and 5 Islamic banks) from 2010 to 2019. The sample is further segregated into Islamic and conventional banks. Ordered logit and random effect ordinary least square models are used to analyze the data. Furthermore, the two-stage least squares approach is used to perform a robustness test.

Findings

This study shows that RD significantly positively impacts CR, with a stronger effect in Islamic banks than in conventional banks. This study also finds that banks’ age and leverage negatively influence CRs. Moreover, banks’ size and total capital have a positive and negative influence on CRs, respectively. This study also shows that the age of Islamic and conventional banks positively and negatively influences the RD scores, respectively. In contrast, the RD score of conventional banks is positively impacted by bank size.

Practical implications

By examining which variables substantially impact RD and, hence, CR scores, bank stakeholders may make better financing, investment and other policy decisions. Investors may choose stocks with a high level of RD in the annual reports as the earlier studies imply that higher RD enhances CR.

Originality/value

Only a few studies have examined the relationship between RD and CRs, while, to the best of the authors’ knowledge, this study is the maiden attempt in the Bangladesh context. This study also compares the link between Islamic and conventional banks.

风险披露对银行信用度的作用以及风险披露的驱动力：伊斯兰银行与传统银行

目的

本研究旨在探讨孟加拉国背景下风险披露（RD）对商业银行信用评级（CR）的影响。它还探讨了影响伊斯兰银行和传统银行研发的因素。

设计/方法论/途径

该样本包括 200 个银行年度观察数据，其中包括 2010 年至 2019 年期间的 20 家商业银行（15 家传统银行和 5 家伊斯兰银行）。样本进一步分为伊斯兰银行和传统银行。使用有序逻辑和随机效应普通最小二乘模型来分析数据。此外，使用两阶段最小二乘法进行稳健性检验。

发现

这项研究表明，RD 对 CR 具有显着的积极影响，在伊斯兰银行中的影响比在传统银行中更强。这项研究还发现，银行的年龄和杠杆率会对 CR 产生负面影响。此外，银行规模和资本总额分别对CR有正向和负向影响。这项研究还表明，伊斯兰银行和传统银行的年龄分别对 RD 分数产生积极和消极的影响。相比之下，传统银行的研发分数受到银行规模的正向影响。

实际影响

通过检查哪些变量对 RD 以及 CR 分数产生重大影响，银行利益相关者可以做出更好的融资、投资和其他政策决策。投资者可以选择年报中RD水平较高的股票，因为早期研究表明较高的RD水平可以提高CR。

原创性/价值

只有少数研究探讨了 RD 和 CR 之间的关系，而据作者所知，这项研究是在孟加拉国背景下的首次尝试。这项研究还比较了伊斯兰银行和传统银行之间的联系。
