Abstract

This research verifies the percentage level of information disclosure related to credit risk of 60 Brazilian institutions classified in the prudential segments S1, S2 and S3 by the Central Bank of Brazil between the years 2013 and 2021. It was observed the compliance with disclosure requirements established in Pillar 3 of the Basel III Accord throughout the period of implementation in Brazil. The period comprises the years 2013 to 2021, with biennial observation of the variables, in which the relationship between the percentages of disclosure observed in each period and the credit ratings of institutions by external rating agencies was analyzed. The research technique used was documentary, with a survey of current prudential regulations and a quantitative approach to the data present in the Pillar 3 Reports published by the institutions and their respective credit ratings. Using the multiple linear regression method with panel data, a positive correlation was found between the dependent variable level of disclosure and the independent variables credit ratings and public control of the institution, i.e., institutions with better ratings tend to disclose more widely its Basel III data. Furthermore, the results indicated that, in general, the level of disclosure was maintained, with a slight increase over the period, in addition to voluntary disclosure of credit risk information by development banks. Finally, it was verified that there is space for new studies that contemplate other risk categories, as well as studies that analyze the content of the reports made public by the analyzed financial institutions, with the aim of verifying the informational quality and the level of details of published texts.
