Every Nigerian bank, but particularly Heritage Bank, needs to set up a corporate governance code and make sure that all of its workers abide by it. This includes the board members, who are in charge of making sure that workers adhere to the code and disciplining those who do not. It is relevant to note that effective corporate governance is crucial to Heritage Bank’s survival and sanitization because it provides the bank with certain indisputable advantages, such as increased profitability, strong and sound cash flow, a solid capital base, and ensuring that the interests of the bank and its employees are aligned for greater productivity. These banks encourage stakeholder interest and public trust, which will eventually boost depositor money and ensure the institution’s growth. A robust banking sector is essential to the expansion of the financial market and the promotion of economic growth and development. On the other hand, issues could arise and negatively impact the bank’s customers as well as the economy as a whole if its corporate governance is inadequate. Therefore, this study aims to examine the impact of corporate governance on Heritage Bank, provide recommendations for improving corporate governance inside the bank, and more thoroughly examine the negative consequences of corporate governance failure on the bank.
