Whistleblowing Practices and Investigation: Implications on the Banking Sector

Whistleblowing is a critical mechanism for promoting transparency and accountability in organizations, particularly in the financial sector where the risk of fraud and financial misconduct is high. This study investigates the effect of legal protections on whistleblower reporting rates in the Nigerian financial sector, focusing on whistleblower legislation, anti-retaliation safeguards, policy enforcement, and reward and incentive mechanisms. The research adopts a descriptive survey design, targeting employees of eight major deposit money banks in Nigeria, including Access Bank Plc, Zenith Bank Plc, Guaranty Trust Bank Plc, United Bank for Africa Plc, First Bank of Nigeria Plc, Fidelity Bank Plc, Stanbic IBTC Bank, and Union Bank of Nigeria. A total of 400 respondents, comprising auditors, compliance officers, risk managers, and operational staff were sampled using a stratified random technique. Data were collected through structured questionnaires and analyzed using SPSS version 25, employing descriptive statistics, Pearson correlation, and multiple regression analysis. Findings reveal that whistleblower legislation and anti-retaliation safeguards have positive and statistically significant effects on reporting rates, indicating that legal and protective frameworks are key drivers of whistleblowing behaviour. In contrast, policy enforcement and reward mechanisms, while positively related to reporting rates, were not statistically significant. The study underscores the need for stronger statutory protections and effective safeguard mechanisms to foster a culture of transparency and accountability in Nigerian financial institutions. Overall, the results highlight that legal protections are fundamental in encouraging whistleblowing and mitigating financial misconduct.
