1.1 Introduction
Inflation is defined as the sustained increase in the general price level of goods and services in an economy over a period of time, resulting in the decline of the purchasing power of money (Mishkin, 2016). It is a critical macroeconomic issue that affects both individuals and institutions, influencing consumption patterns, investment decisions, and overall economic growth. In Nigeria, inflation has been a recurring challenge, driven by factors such as rising food and energy prices, exchange rate volatility, government fiscal deficits, and structural weaknesses in the economy (Sanusi, 2010).
The Central Bank of Nigeria (CBN) is the primary monetary authority responsible for maintaining price stability and ensuring sustainable economic growth through the formulation and implementation of monetary policy (CBN, 2022). Monetary policy involves the regulation of money supply, interest rates, and credit availability to achieve macroeconomic objectives, including the control of inflation (Anyawu, 2011).
The CBN uses instruments such as the Monetary Policy Rate (MPR), cash reserve requirements, and open market operations to influence liquidity in the economy and stabilize prices (Obstfeld & Rogoff, 2014). 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
Inflation control in Nigeria has been a central concern since the establishment of the Central Bank of Nigeria in 1958. According to Sanusi (2010), the CBN was created to regulate the supply of money, maintain monetary stability, and promote a sound financial system. In its early years, the bank focused primarily on currency issuance and maintaining reserves, but as the economy grew, it became increasingly involved in managing inflation through monetary policy interventions. Anyanwu (2011) reported that the CBN initially relied on direct instruments, such as credit ceilings and interest rate controls, to influence lending and borrowing activities. These measures were considered effective during the 1960s and 1970s, as Nigeria experienced moderate inflation due to government-controlled prices and a largely agrarian economy.
According to Mishkin (2016), inflation is defined as the persistent increase in the general price level of goods and services over a period of time, leading to a decline in the purchasing power of money. Mishkin reported that inflation, if uncontrolled, reduces the real income of consumers, distorts investment decisions, and creates uncertainty in the business environment. In Nigeria, inflation has been a persistent economic challenge, affecting households, businesses, and the government's ability to maintain sustainable economic growth.
Sanusi (2010) asserted that the Nigerian economy has experienced various periods of high inflation, often driven by both internal and external factors, including global oil price fluctuations, exchange rate instability, supply chain disruptions, and structural weaknesses in the domestic economy. Sanusi reported that these factors combine to limit the effectiveness of monetary policy in controlling price levels, thus making inflation a multidimensional problem. According to Anyanwu (2011), the Nigerian Central Bank plays a central role in the formulation and implementation of monetary policy to manage inflation, stabilize the financial system, and promote economic growth. Anyanwu affirmed that monetary policy involves the regulation of money supply, credit availability, and interest rates to influence aggregate demand and, by extension, the overall price level.
The Central Bank of Nigeria (CBN) utilizes both quantitative and qualitative instruments in executing its monetary policy objectives. Quantitative instruments, such as the Monetary Policy Rate (MPR), cash reserve requirements, and open market operations, are aimed at regulating liquidity and influencing borrowing and lending activities in the economy (CBN, 2022). According to CBN (2022), these instruments are intended to create an environment that encourages price stability, reduces inflationary pressures, and promotes investor confidence. On the other hand, qualitative instruments, including credit rationing and moral suasion, are used to guide the allocation of credit to priority sectors of the economy. CBN asserted that the combination of these instruments is necessary to ensure effective control of inflation, although the outcomes depend on proper policy execution and the responsiveness of the economy.
Obstfeld and Rogoff (2014) contended that the effectiveness of monetary policy in controlling inflation is often influenced by external shocks, such as fluctuations in global commodity prices and foreign exchange rates, which can undermine domestic policy measures. They reported that in open economies like Nigeria, the interplay between international and domestic economic factors creates additional challenges for central banks, requiring careful calibration of monetary interventions. Ogunleye (2012) stated that high inflation adversely affects the purchasing power of households, reduces savings, discourages long-term investment, and creates uncertainty in both domestic and foreign investment decisions. According to Ogunleye, persistent inflation may also exacerbate income inequality, as low- and middle-income households are disproportionately affected by rising prices of essential goods and services.
This study is set against the backdrop of persistent inflationary pressures in Nigeria, the critical role of the CBN in stabilizing the economy, and the need to evaluate the effectiveness of monetary policy instruments in controlling inflation.
1.3 Statement of Problems
Investigation revealed that inflation remains one of the most persistent challenges facing the Nigerian economy, affecting both the purchasing power of citizens and the overall stability of the financial system. Rapid increases in the general price level lead to reduced consumer confidence and limit the ability of households to plan effectively for the future. While the Central Bank of Nigeria (CBN) implements monetary policies aimed at controlling inflation, these measures are not always fully effective in curbing persistent price increases. On the one hand, the use of interest rate adjustments, cash reserve requirements, and open market operations is intended to regulate money supply and stabilize prices (Obstfeld & Rogoff, 2014).
Furthermore, small and medium enterprises (SMEs), as well as average consumers, bear the brunt of these price fluctuations, leading to reduced economic productivity and heightened financial stress. Moreover, inconsistent policy implementation and delays in response to economic shocks make it difficult for monetary interventions to achieve their intended results (Anyanwu, 2011). It is against this backdrop that this study seeks to examine the control of inflation using Central Bank of Nigeria monetary policy, identifying the factors that influence its effectiveness and the areas where policy intervention is most needed.
1.4 Aim and Objectives of Study
The aim of this study is to examine the control of inflation using the Central Bank of Nigeria (CBN) monetary policy. In achieving this aim, the following specific objectives were laid out as follows:
- To assess the impact of the Monetary Policy Rate (MPR) on inflation control in Nigeria.
- To examine the role of cash reserve requirements in regulating liquidity and stabilizing prices.
- To analyze the effectiveness of open market operations in controlling money supply and inflation.
- To investigate the influence of external factors, such as oil price shocks and exchange rate fluctuations, on the success of monetary policy.
- To identify existing challenges in the implementation of CBN monetary policy and propose strategies for improvement.
1.5 Research Questions
The study came up with research questions so as to be able to ascertain the above stated objectives. The specific research questions for the study are stated below as follows:
- How does the Monetary Policy Rate (MPR) influence inflation control in Nigeria?
- What is the role of cash reserve requirements in regulating liquidity and stabilizing prices?
- How effective are open market operations in controlling money supply and inflation?
- What is the impact of external factors, such as oil price shocks and exchange rate fluctuations, on the success of monetary policy?

1.7 Significance of Study
It is believed that at the completion of the study, the research will provide reliable evidence on the effectiveness of the Central Bank of Nigeria's monetary policy in controlling inflation. The study will also help policymakers design more responsive and targeted interventions, strengthen financial sector stability, and improve the ability of businesses and households to plan financially.
Furthermore, the study will assist businesses and households in understanding how inflation trends affect purchasing power and cost of living. In addition, the research will also inform financial institutions about the impact of monetary policy on lending rates, liquidity management, and investment strategies.
Lastly, the research will contribute to academic knowledge and provide a reference for future studies on monetary policy and inflation control in Nigeria.
1.8 Scope and Limitations of the Study
The scope of the study is limited to the operations of the Central Bank of Nigeria within Lagos State, focusing on its monetary policy instruments such as the MPR, cash reserve requirements, and open market operations.
The study was limited by delays from respondents in providing accurate data, financial constraints, insufficient secondary data, and the limited time frame allocated for the research. On the other hand, external economic factors beyond CBN control were considered as potential constraints to achieving fully accurate conclusions.
