ABSTRACT
The objective of this study is focused on the impact of monetary policy on the profitability of banks in Nigeria. Specifically, the study evaluated the impact of money supply on the profitability of deposit money banks in Nigeria, assessed the effect of cash reserve requirements on bank profitability, examined the influence of interest rates on the profitability of banks, and analyzed the effect of exchange rate fluctuations on the profitability of banks in Nigeria. Ex-post facto research design was used in the study to accomplish the stated goal. Information was gathered from public annual reports of the banks under consideration as secondary sources. All deposit money banks that were listed on the Nigerian Exchange Group between 2016 and 2023 made up the population. Because the ten (10) specified banks had complete financial data during the study's time frame, these institutions' samples were purposefully chosen. Thereafter, multiple regressions and descriptive statistics were used in the data analysis process using the statistical package for social sciences (SPSS). Regression results demonstrate a significant positive impact of CRR (t = 3.3088, p < 0.05) and money supply (MS) (t = 2.3747, p < 0.05) on profitability before tax (PBT), with CRR contributing a 15% increase in PBT for each unit rise. Liquidity (LIQD) positively influences the cost-to-income ratio (T = 2.7619, p < 0.05), suggesting that increased liquidity raises operational costs. However, exchange rates (EXR) exhibit a significant negative impact on PBT (t = -2.4373, p < 0.05), highlighting the adverse effects of exchange rate fluctuations on bank profitability. The model's robustness is supported by high R² values (92% for PBT) and the absence of autocorrelation, as indicated by Durbin-Watson statistics. These results emphasize the critical role of monetary policies in shaping the financial performance of Nigerian DMBs. The study, among others, recommends that banks in Nigeria should implement effective risk management strategies to mitigate the adverse effects of monetary policy changes on their operations.

CHAPTER ONE
INTRODUCTION (Preview)
1.1 Background to the Study
The banking sector plays a pivotal role in the economic development of any nation by facilitating capital formation, financial intermediation, and economic growth. In Nigeria, Osho & Adelalu (2020) averred that banks are instrumental in mobilizing savings and directing them toward productive investments. However, when the economy is faced with challenges such as inflation, unemployment, and increased interest rates, this discourages investments, causing decreased trade, as investor confidence is undermined, causing market uncertainties, as well as disruptions in supply chains (Anamakiri, 2018). This macroeconomic variable, in no doubt, heavily affects the banking sector.

Over the years, the CBN has employed various monetary policy instruments such as the Monetary Policy Rate (MPR), Cash Reserve Requirement (CRR), and Open Market Operations (OMO) to regulate the economy. These tools are designed to stabilize inflation, ensure exchange rate stability, and foster economic growth. Monetary policy refers to the actions taken by a central bank, such as the Central Bank of Nigeria (CBN), to control money supply, interest rates, and credit availability to achieve specific economic objectives. Ugwu, Peter & Udolu (2020) defined monetary policies as an attempt by the monetary authorities to emphasize the level of aggregate economic policies as an attempt by it to influence the level of aggregate economic activities by controlling the quantity and direction of money and credit availability. However, the effectiveness of these policies has significant implications for the financial sector's stability and the profitability of commercial banks.

Owing to the fact that banks operate in a dynamic environment, where there is a change in monetary policies, Quan (2023) averred that these policy changes can create opportunities or pose challenges. For instance, a contractionary policy aimed at reducing inflation may increase interest rates, potentially limiting borrowing and reducing profit margins. Empirical studies by Afolabi, Adeyemi, Salawudeen, & Fagbemi (2020) have suggested a mixed relationship between monetary policy and bank operation in Nigeria. The authors argued that while policies that stabilize the economy can foster confidence, encourage investment, and ultimately benefit banks, on the other hand, inconsistent policy implementations and regulatory challenges may negatively affect banks' operations and efficiency. For example, sudden adjustments in the CRR can constrain banks' lending abilities, while unpredictable exchange rate policies can lead to foreign currency losses.

Conversely, Boaten (2020) explained that the interaction between monetary policies and bank profitability, whether in developed or developing countries, is also shaped by external factors, including global economic trends and local economic conditions. For instance, during periods of high inflation or economic downturns, banks may struggle to maintain profitability due to reduced borrowing and heightened loan defaults. Whereas  periods of economic growth and stable policies tend to provide a conducive environment for bank operations, changes in the Cash Reserve Requirement (CRR) often restrict the liquidity available to banks, reducing their capacity to extend loans and thereby impacting profitability.

In Nigeria, Borhan & Towpek (2018) pointed out that monetary policy influences not only profitability but also banks' risk management practices. By controlling liquidity and credit availability, monetary policies directly affect the risk appetite of banks, particularly concerning their lending activities. Howbeit, striking a balance between profitability and risk remains a critical challenge for banks operating in Nigeria’s volatile economic environment. This study, therefore, seeks to investigate the impact of monetary policy on the profitability of banks in Nigeria.

1.2 Statement of the Problem

It is no doubt that the profitability of banks is crucial for maintaining a stable financial system and fostering economic growth. However, in Nigeria, banks often face fluctuating profitability levels due to the volatile economic environment and inconsistent monetary policies. The Central Bank of Nigeria's efforts to manage inflation, stabilize the exchange rate, and promote economic growth through monetary policies have sometimes yielded unintended consequences for the banking sector. For instance, frequent adjustments in the Monetary Policy Rate (MPR) can create uncertainty in lending and borrowing, affecting banks’ interest income. Furthermore, studies on the impact of financial regulation on profitability as evaluated by return on asset and net interest margin undertaken by Ugwu et al. in 2020 and Mulwa in 2015, respectively, indicated an insignificant connection among the variables.

Existing studies have examined the relationship between monetary policy and bank profitability but have produced mixed results. For example, Akomolafe et al. (2015) found that interest rates and liquidity significantly affect the profitability of insurance companies, but similar studies focusing on deposit money banks have highlighted gaps in understanding how cash reserve requirements and exchange rate fluctuations specifically influence their profitability. This inconsistency suggests the need for a more targeted investigation into the interplay of these variables in the Nigerian banking context. Couple with the fact that the Nigerian banking industry has witnessed increasing operational costs and declining profit margins due to volatile macroeconomic factors, including inflation and currency devaluation (Adegbite & Aluko, 2020), the extent to which monetary policy variables such as money supply and liquidity mitigate or exacerbate these challenges remains underexplored.

Bizarrely, there is a notable lack of recent empirical studies that integrate modern econometric models to evaluate the long-term effects of monetary policy on bank profitability. Many studies emphasize the theoretical aspects of monetary policy without providing sufficient empirical evidence on how these policies affect banks' bottom lines. This study aims to bridge this gap by providing empirical insights into how monetary policies influence the profitability of banks in Nigeria, thereby offering practical recommendations for policymakers and banking institutions.

1.3 Objectives of the Study

CHAPTER FOUR: DATA PRESENTATION AND ANALYSIS
MAJOR FINDINGS (Preview)
The analysis results were presented in tables and charts. Based on the results obtained from the analysis, the following major findings were made:

i. The study found that monetary policy has a significant positive effect on the profit before tax (PBT) of quoted deposit money banks in Nigeria, as evidenced by the fixed effect regression result, which showed a coefficient of 0.1524 and a t-statistic of 3.3088 (p < 0.05) for cash reserve ratio (CRR).

This was further supported by the significant negative effect of exchange rate (EXR), with a coefficient of -1.1852 and a t-statistic of -2.4373 (p < 0.05), while money supply (MS) had a significant positive effect, with a coefficient of 1.4558 and a t-statistic of 2.3747 (p < 0.05). The model recorded an R² of 0.92, indicating that the explanatory variables accounted for 92% of the variation in profit before tax. This implies that changes in monetary policy variables significantly influence the profitability of quoted deposit money banks in Nigeria.

ii. The study found that monetary policy has a significant effect on the cost-to-income ratio (CIR) of quoted deposit money banks in Nigeria, as evidenced by the random effect regression result, which showed that liquidity had a positive and significant effect on CIR, with a coefficient of 0.0238 and a t-statistic of 2.7619 (p < 0.05). However, the other monetary policy variables, including cash reserve ratio (CRR), interest rate (INT), exchange rate (EXR), and money supply (MS), did not demonstrate statistically significant effects. The model recorded an R² of 0.6990, indicating that the explanatory variables accounted for approximately 69.9% of the variation in the cost-to-income ratio. This implies that liquidity is a significant determinant of the cost-to-income ratio of quoted deposit money banks in Nigeria.
