1.1 Introduction
Bank capitalization refers to the amount of financial capital that a bank has available to support its operations, absorb losses and undertake lending activities. Lending rate, on the other hand, refers to the interest charged by a bank when it provides loans to customers. The relationship between the two is important because a bank with adequate capital is expected to have greater financial strength and a better ability to support credit activities. The Central Bank of Nigeria (CBN) regards adequate capitalization as an important requirement for maintaining a stable and resilient banking system and supporting economic development (CBN, 2025). In Nigeria, capitalization has remained an important part of banking regulation. The history of the banking industry shows repeated regulatory efforts to strengthen banks whenever weaknesses in the system become evident. The 2004 banking consolidation exercise raised the minimum capital base from ₦2 billion to ₦25 billion, resulting in substantial mergers and acquisitions and a reduction in the number of deposit money banks (CBN, 2005).
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 questions, limitation of the study and definition of terms.
1.2 Background of Study
Historically, bank capitalization in Nigeria is closely connected with the development of banking regulation. Modern banking activities became established in Nigeria during the late nineteenth and early twentieth centuries, but the sector initially operated with limited domestic regulation. The Banking Ordinance of 1952 represented an important step toward controlling banking activities and preventing the establishment of weak and unviable banks (CBN, 2015). According to the Central Bank of Nigeria (CBN), capitalization is an important part of banking regulation because adequate capital strengthens the ability of banks to absorb unexpected losses and remain stable during economic difficulties. In simple terms, capital represents the financial cushion that protects a bank when its business does not go as expected.
Similarly, the history of Nigerian banking shows that weak capital positions have often contributed to concerns about the strength and survival of financial institutions. The CBN's review of banking reforms explained that the industry moved from a period of relatively limited regulation to stronger regulatory control as problems within the banking system became more evident (CBN, 2015). The introduction of minimum capital requirements was therefore aimed at preventing banks from operating with financial resources that were too small to support their activities and absorb losses.
The global financial crisis and subsequent problems in the Nigerian banking sector led to further reforms after 2008. Greater attention was given to risk management, corporate governance, supervision and financial stability. These measures reflected the understanding that adequate capital alone was not enough to guarantee a healthy banking system. In 2024, the CBN introduced another major recapitalization programme. Existing banks were required to meet higher minimum paid-in capital requirements by March 31, 2026. The policy was aimed at strengthening the banking sector, improving resilience and increasing banks' capacity to support economic growth through credit provision (CBN, 2025).
Likewise, the 2004 banking consolidation programme represented one of the major efforts to improve capitalization in Nigeria. The CBN required banks to increase their minimum capital base from ₦2 billion to ₦25 billion by December 2005. Banks were expected to raise additional funds or combine through mergers and acquisitions to meet the new requirement (CBN, 2005). The reform reduced the number of deposit money banks from 89 to 25 and created larger institutions with stronger capital bases.
Olamide (2016) investigated the effect of capitalization on credit creation in Nigeria and reported that bank capitalization, lending rate and deposit volume were significant factors in explaining banks' credit creation. This suggests that capital strength matters when banks decide how much credit to provide. A bank with adequate capital is capable of taking on a greater level of lending activity without being as heavily constrained by capital requirements. Along the same line, Oyebowale (2020) reported that capitalization was among the factors associated with bank loan supply in Nigeria.
This study is set against the backdrop of the ongoing transformation of the Nigerian banking sector through recapitalization, changing monetary conditions and the continuing need for accessible bank credit.
1.3 Statement of Problems
Investigation revealed that Nigerian banks operate under a changing regulatory environment where stronger capital is expected to improve their ability to absorb losses and provide credit. The Central Bank of Nigeria (CBN) introduced a new recapitalization programme requiring commercial banks with international authorization to raise minimum capital to ₦500 billion, national banks to ₦200 billion, and regional banks to ₦50 billion by March 31, 2026 (CBN, 2025). On the other hand, stronger capitalization has the potential to increase banks' capacity to lend, but it does not automatically translate into cheaper loans because lending rates are also affected by monetary policy, inflation, liquidity and operating costs.
Furthermore, lending rates in Nigeria have remained relatively high despite successive banking reforms and recapitalization exercises. CBN data show that lending rates continue to reflect wider monetary and economic conditions, while the monetary policy rate and other market factors influence the cost of funds to banks and their customers (CBN, 2026). Additionally, there is still a practical concern about whether improved capitalization will lead to a reduction in lending rates for individuals and businesses. It is against this backdrop that this study seeks to examine the impact of improved capitalization on Nigerian banks lending rate.
1.4 Aim and Objectives of Study
The aim of this study is to examine the impact of improved capitalization on Nigerian banks' lending rates. The specific objectives of this research are to:
