1.1 Introduction
Accounting is the systematic process of identifying, recording, classifying, summarizing, and interpreting financial transactions to provide meaningful information for decision-making (Horngren, Sundem, & Elliott, 2013). It serves as the backbone of financial management in organizations, including deposit money banks, by ensuring that financial data is accurate, reliable, and available for both internal and external stakeholders. Internal control, on the other hand, refers to the policies, procedures, and practices put in place within an organization to safeguard assets, ensure the reliability of financial reporting, promote operational efficiency, and encourage adherence to laws and regulations (COSO, 2013).
Deposit money banks operate in a dynamic and highly regulated environment, where the handling of large volumes of funds and transactions requires meticulous attention to accuracy and security. Accounting systems in banks are designed to capture and report financial activities such as deposits, loans, interest income, and expenditures, thereby providing critical information for management, and investors (Adeniyi, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Accounting and internal control systems form the foundation of effective financial management and operational stability in deposit money banks. Accounting, according to Horngren, Sundem, and Elliott (2013), is the process of systematically recording, summarizing, and interpreting financial transactions to provide information useful for decision-making. This process enables banks to generate accurate financial statements, assess profitability, monitor liquidity, and ensure compliance with regulatory requirements. Internal control, on the other hand, is a structured framework of policies, procedures, and practices designed to safeguard assets, prevent fraud, promote efficiency, and ensure that financial reporting is reliable (COSO, 2013).
The integration of accounting systems and internal controls is crucial in deposit money banks where high volumes of financial transactions occur daily, creating significant operational and financial risks. According to Adeniyi (2019), the efficiency of accounting systems directly impacts the decision-making ability of management in banks. He reported that robust accounting practices ensure that financial data is accurate and timely, thereby enabling management to evaluate performance, allocate resources effectively, and meet strategic objectives.
Olaoye and Afolabi (2020) asserted that internal control mechanisms serve as a protective measure against fraud and financial mismanagement. These controls, which include authorization procedures, segregation of duties, internal audits, and compliance monitoring, are critical in ensuring that financial operations are conducted according to established standards and regulations. The Nigerian banking sector, in particular, has experienced numerous challenges related to accounting and internal control systems. Sanusi (2012) stated that prior to banking reforms, several deposit money banks in Nigeria suffered operational inefficiencies and financial irregularities due to weak internal control structures and ineffective accounting practices. He affirmed that these weaknesses contributed to significant losses, institutional failures, and erosion of public trust. Similarly, Olowokure, Tanko, and Nyor (2016) contended that lapses in internal control systems and inadequacies in accounting processes lead to misstatements in financial reporting, fraud, and operational inefficiencies.
According to Adeyemi and Fagbemi (2018), the adoption of digital banking and automated financial transaction systems has increased both efficiency and complexity in banking operations. They reported that while technology facilitates faster transaction processing, it also introduces new risks, such as system manipulation, cyber fraud, and errors in electronic record-keeping. These risks necessitate the continuous evaluation and enhancement of internal control measures alongside robust accounting practices. On the other hand, researchers such as Izedonmi and Egbide (2017) asserted that banks with strong internal control frameworks and accurate accounting systems demonstrate higher operational efficiency, improved financial performance, and better compliance with regulatory requirements.
The interplay between accounting systems and internal control frameworks in deposit money banks is also evident in corporate governance practices. According to Nwankwo (2015), effective corporate governance in banks is supported by reliable accounting information and robust internal controls, which collectively ensure accountability, transparency, and operational integrity. He contended that banks with weak accounting and control systems often face higher incidences of financial mismanagement, operational inefficiency, and regulatory non-compliance. On the other hand, studies by Adeyemi (2020) affirmed that proper accounting and internal control systems significantly influence decision-making, operational efficiency, and overall financial performance, thereby contributing to the sustainability of banking operations.
The effectiveness of accounting and internal control systems in deposit money banks is therefore a central concern for banking operations, regulatory compliance, and stakeholder confidence. While several reforms have been implemented in Nigeria's banking sector, challenges related to fraud, mismanagement, and operational inefficiencies continue to arise, suggesting that some banks still operate with inadequate systems (Sanusi, 2012; Olowokure et al., 2016). This study is set against the backdrop of the need to understand how accounting and internal control systems affect the operational performance, risk management, and financial stability of deposit money banks, particularly within the Nigerian banking sector.
1.3 Statement of Problems
Investigation revealed that the effectiveness and stability of the banking sector depend largely on the strength of accounting practices and the reliability of internal control systems established within financial institutions. Deposit money banks operate in an environment where large volumes of financial transactions are processed daily, making accurate accounting records and strong internal control mechanisms essential for transparency, accountability, and operational efficiency. Accounting systems are expected to provide reliable financial information that supports management decisions, regulatory compliance, and public confidence in the banking sector (Adeniyi, 2019).
In many banking institutions, internal control systems are designed to safeguard assets, ensure the accuracy of financial records, prevent fraud, and promote adherence to established policies and procedures. On the other hand, weaknesses in accounting systems or lapses in internal control practices often create opportunities for financial mismanagement, errors in reporting, and fraudulent activities that threaten the stability of banking operations (Olowokure, Tanko, & Nyor, 2016).
Furthermore, the Nigerian banking sector has experienced several incidents in the past where poor internal control structures and weak accounting practices contributed to financial irregularities and institutional failures (Sanusi, 2012). It is against this backdrop that this study seeks to examine the effect of accounting and internal control system in deposit money banks operation.
1.4 Aim and Objectives of Study
