1.0 Introduction
1.1 Background of Study
The banking sector witnessed major reforms between 2004 and 2005 when the CBN implemented a bank consolidation policy, increasing the minimum capital requirement for banks from ₦2 billion to ₦25 billion (Soludo, 2004). Since then, the CBN has continued to adjust its monetary policy framework in response to economic conditions, such as the 2008 global financial crisis, which prompted the introduction of liquidity injection measures to stabilize the banking industry (Sanusi, 2010). Monetary policy plays a crucial role in shaping the financial and economic landscape of any country. It refers to the strategies employed by a central bank to regulate money supply, control inflation, and stabilize the economy through instruments such as interest rates, open market operations, and reserve requirements (Friedman, 1968). In Nigeria, the Central Bank of Nigeria (CBN) is responsible for formulating and implementing monetary policies aimed at ensuring price stability, fostering economic growth, and maintaining financial system stability (CBN, 2021).
The Nigerian banking industry has undergone significant reforms over the years, driven by changes in monetary policy. These reforms include interest rate deregulation, capital base consolidation, and exchange rate policies, all of which have influenced the performance of banks in terms of profitability, liquidity, and lending behavior (Mishkin, 2007). The effectiveness of monetary policy in Nigeria has been tested by economic challenges such as inflation, exchange rate volatility, and fluctuations in global oil prices, which impact the financial sector's stability and growth.
In recent years, Nigeria's banking sector has experienced various challenges, including inflationary pressures, exchange rate volatility, and fluctuating interest rates, all of which are closely linked to the monetary policy stance of the CBN. The effectiveness of monetary policy in ensuring financial stability and fostering sustainable growth in the banking industry remains a subject of debate among policymakers and researchers (CBN, 2021). Monetary policy refers to the actions undertaken by a nation's central bank to control money supply, interest rates, and credit availability to achieve macroeconomic objectives such as price stability, economic growth, and financial stability (Friedman, 1968). In Nigeria, monetary policy is primarily formulated and implemented by the Central Bank of Nigeria (CBN) to regulate inflation, stabilize the currency, and promote a sound financial system.
According to Mishkin (2007), the banking industry plays a crucial role in economic development by facilitating financial intermediation, providing credit to individuals and businesses, and ensuring the smooth functioning of payment systems. However, the performance of banks is significantly influenced by monetary policy measures such as open market operations (OMO), reserve requirements, and the monetary policy rate (MPR) (Mishkin, 2007). Therefore, this study aims to investigate the effect of monetary policy on the performance of the banking industry in Nigeria.
1.2 Statement of Problems
Investigation revealed that the effectiveness of monetary policy in ensuring a stable and efficient banking industry in Nigeria is a subject of continuous debate among policymakers, economists, and financial analysts. The Nigerian banking sector operates within a volatile economic environment characterized by inflation, exchange rate fluctuations, and interest rate instability, all of which are influenced by monetary policy decisions (Eze & Okpala, 2020).
Additionally, the CBN employs instruments such as cash reserve requirements and open market operations to regulate money supply. However, frequent adjustments in these policies create uncertainties for banks, making it difficult for them to plan long-term investment strategies (Mishkin, 2007). When liquidity is tightened, banks struggle to meet loan demands, while excess liquidity could lead to inflationary pressures, affecting economic stability.
Furthermore, the interest rate adjustments influence the cost of borrowing and lending, directly affecting banks' revenue generation. High monetary policy rates set by the Central Bank of Nigeria (CBN) often lead to increased lending rates, discouraging businesses and individuals from accessing credit, which in turn affects banks' loan portfolios and overall financial performance (Ajayi & Atanda, 2012). It is against the backdrop that this study seeks to analyze how various monetary policy instruments influence bank profitability, liquidity management, credit creation, and overall financial stability in the country.

1.9 Definition of Terms
Monetary Policy:
Monetary policy refers to the actions taken by a country's central bank or monetary authority to regulate the supply of money, interest rates, and credit in the economy. It aims to achieve macroeconomic goals such as controlling inflation, managing employment levels, stabilizing the currency, and fostering economic growth (Ogun, 2016). In the context of Nigeria, the Central Bank of Nigeria (CBN) uses monetary policy tools such as interest rates, open market operations, and reserve requirements to influence the banking sector and the broader economy.
Banking Industry:
The banking industry encompasses all financial institutions engaged in the business of accepting deposits, lending money, and providing various financial services, such as investment advice and currency exchange. In Nigeria, the banking industry consists of commercial banks, microfinance banks, development banks, and other financial service providers regulated by the Central Bank of Nigeria (CBN) (Adeyemi, 2014). This sector plays a vital role in the country's economic development, offering crucial services for individuals and businesses.
Performance of Banks:
The performance of banks refers to how effectively banks manage their operations to achieve financial stability and profitability. This is typically assessed using indicators such as return on assets (ROA), return on equity (ROE), liquidity ratios, capital adequacy, and non-performing loans (NPLs). The financial health of banks is crucial in determining the level of credit available to the economy and their ability to contribute to economic growth (Ajayi & Alani, 2017).
Interest Rates:
Interest rates are the costs that borrowers pay for the use of money they borrow from banks, and the return that lenders earn on their deposits. Central banks use interest rates as a key tool in monetary policy to control inflation and stabilize the economy. In Nigeria, the CBN sets benchmark interest rates, such as the Monetary Policy Rate (MPR), which directly influences the lending and deposit rates in commercial banks (Nwachukwu & Okoro, 2016).
