This study examines the effect of ethical accounting standards on the quality of financial reports of
banks in Nigeria. To achieve this objective, data was collected from primary and secondary sources. The
secondary sources were from textbooks, journals and unpublished thesis. The primary source involves a well
structured questionnaire of four sections of sixty seven questions administered to a sample of eight banks
systematically collected from the twenty four banks in Nigeria. The data generated from the questionnaires was
analysed using econometric models such as diagnostic test, Augmented Dickey-Fuller, ordinary least square
and Granger Causality. The results reveal that ethical accounting standards is significantly related to the quality
of financial reports of banks in Nigeria. On the basis of the findings, the study concluded that ethical accounting
standards are fundamentally necessary for accountants to produce quality financial reports free from material
misstatements. The authors recommend the following among others: that professional accountants as custodian
and producers of accounting information should adhere to the codes of professional best practices issued by
relevant professional bodies, banks in Nigeria should establish ethics departments to ensure that activities
adhere to the codes of ethics including the financial reporting process, accountants and accounting officers in
Nigerian banks should adhere to the International Financial Reporting
