Banking institutions occupy a central position in the nations’ financial system and are essential agents in the development process of the economy. By intermediating between the surplus and deficit spending units, banks increase the quantum of National savings and investments and hence national output. By granting credits, banks create money thus influencing the level of money supply which is an essential item in the growth of national income as it determines the level of economic activities in the country.

Banks are central to the payments system by facilitating economic transactions between various national and international economic units and by so doing encourage and promote trade, commerce and industry.

For banks to be able to function effectively and contribute meaningfully to the development of a country, the industry must be stable, safe and sound. And for these conditions to be obtained there must be a sound accounting system, which is occasioned by an internal control system.

In view of the economic growth in companies’ size and complexities, proper management of modern business undertakings are not possible unless they have an effective system of internal control.

A system of effective internal controls is a critical component of bank management and a foundation for the safe and sound operation of banking organizations. A system of strong internal controls can help to ensure that the goals and objectives of a banking organization will be met, that the bank will achieve long-term profitability targets and maintain reliable financial and managerial reporting. Such a system can also help to ensure that the bank will comply with laws and regulations as well as policies, plans, internal rules and procedures, and decrease the risk of unexpected losses or damage to the Bank’s reputation.

Internal control, the strength of every organization, has become of paramount importance today in Nigerian banks. The reason being that the control systems in any organization is a pillar for an efficient accounting system.

The need for the internal control systems in organizations, especially banks, cannot be undermined, due to the fact that the banking sector, which has a crucial role to play in the economic development of a nation, is now being characterized by macro economic instability, slow growth in real economic activities, corruption and the risk of fraud.

Fraud, which is the major reason for setting up an internal control system, has become a great pain in the neck of many Nigerian bank managers. It has also become an unfortunate staple in Nigeria’s international reputation. Fraud is really eating deep into the Nigerian banking system and that any bank with a weak internal control system, is dangerously exposed to bank fraud.

The CBN reported that cases of attempted fraud and forgery in banks, as at half-year 2007 have surpassed what was recorded for the whole year 2006. The CBN half-year report for 2007, revealed a total of 741 cases of attempted fraud and forgery, involving 5.4 billion, $35,406.1, 150 Euros were reported as at June, 2007. In 2006, 1,193 cases were reported involving 4.6 billion, $1.8 million and 14,389.7 pound sterling. The CBN also reported that the backward development was attributable to weaknesses in the internal control systems of the banks. This has clearly painted the picture of how fraud has penetrated in the financial strength of Nigerian Banks.

In a nut-shell, the damage which this menace, called fraud has done to the banks is innumerable and needs urgent attention. Therefore, the attempt to put an end to this economic degradation, gave rise to the topic of this research study the effect of internal control on organizational performance in the banking sector with Eco bank Nigeria PLC as a case study. However, this study is aimed at verifying the conception that an effective and efficient internal control system is the best control measure for preventing and detecting fraud, especially in the banking sector.
