LITERATURE REVIEW
Conceptual Framework
Monetary Policy
Monetary policy plays a vital role in managing and stabilizing an economy. It refers to the actions and measures taken by the central bank or monetary authority to control the money supply, interest rates, and credit conditions to achieve specific objectives, such as price stability and economic growth (Owoye & Oloni, 2019).
The Central Bank of Nigeria (CBN) formulates and implements monetary policy in Nigeria. The CBN utilizes various instruments to influence the money supply and credit conditions in the economy. These instruments include open market operations (OMO), reserve requirements, and the monetary policy rate (MPR) (Ogbonna et al., 2020).
Open market operations (OMO) are conducted by the central bank through the buying and selling of government securities in the open market. When the central bank sells government securities, it absorbs money from the banking system, reducing the money supply and curbing inflationary pressures. Conversely, when it buys government securities, it injects money into the system to stimulate economic activity (Owoye & Oloni, 2019).
Reserve requirements refer to the minimum amount of reserves that commercial banks are required to hold with the central bank. By adjusting reserve requirements, the central bank can influence the lending capacity of banks and control the money supply. Increasing reserve requirements reduces the amount of funds available for lending, thereby curbing inflationary pressures (Ogbonna et al., 2020).
The monetary policy rate (MPR) is the benchmark interest rate at which the central bank lends to commercial banks. It serves as a signal to the banking system and the market regarding the monetary policy stance. Changes in the MPR affect the cost of borrowing, influencing lending rates and ultimately impacting economic activity and inflation levels (Olatunji & Alimi, 2021).
The primary objective of monetary policy is to achieve price stability by controlling inflation. Price stability is essential for sustainable economic growth, as it promotes business and consumer confidence, facilitates investment decisions, and encourages long-term planning (Owoye & Oloni, 2019). Through the implementation of various monetary policy instruments, the central bank aims to manage inflationary pressures and maintain price stability in the economy.
Monetary policy also plays a role in influencing other macroeconomic variables, such as exchange rates, employment, and economic growth. By adjusting interest rates and managing the money supply, monetary policy can influence the value of the domestic currency and maintain a stable exchange rate regime (Olatunji & Alimi, 2021). Additionally, an accommodative monetary policy can stimulate economic activity and contribute to employment generation and overall economic growth (Ogbonna et al., 2020).
In recent years, the effectiveness of monetary policy in achieving its objectives has been a subject of study and debate. Researchers have examined the transmission mechanisms through which monetary policy actions impact the economy. The understanding of these mechanisms is crucial for policymakers to formulate effective measures and strategies to achieve desired outcomes (Ezike & Chukwu, 2021).
In summary, monetary policy is a vital tool used by the central bank to manage and stabilize an economy. It involves the use of various instruments, including open market operations, reserve requirements, and the monetary policy rate, to influence the money supply, credit conditions, and interest rates. The primary objective of monetary policy is to achieve price stability and control inflation. Understanding the concepts and mechanisms of monetary policy is essential for policymakers in formulating and implementing effective measures to maintain economic stability and promote sustainable growth.
Inflation
Inflation refers to the sustained increase in the general level of prices of goods and services in an economy over some time. It is typically measured by changes in the Consumer Price Index (CPI) or the Wholesale Price Index (WPI). Inflation erodes the purchasing power of money and affects various aspects of the economy (Ezike & Chukwu, 2021).
In Nigeria, inflation has been a persistent challenge, with fluctuating rates over the years. High inflation rates have adverse effects on individuals, businesses, and the overall economy. It reduces the real value of income, erodes savings, and impacts investment decisions (Ajisafe et al., 2021). According to the National Bureau of Statistics (NBS), Nigeria experienced double-digit inflation rates in recent years, with the Consumer Price Index (CPI) reaching 15.75% in December 2021 (NBS, 2022).
Understanding the causes and drivers of inflation is crucial for policymakers in formulating effective strategies to manage it. Inflation can result from various factors, including demand-pull inflation, cost-push inflation, and supply-side shocks (Ezike & Chukwu, 2021). Demand-pull inflation occurs when aggregate demand exceeds aggregate supply, leading to price increases. Cost-push inflation, on the other hand, arises from increases in production costs, such as wages and raw material prices. Supply-side shocks, such as disruptions in the supply of essential goods or changes in global commodity prices, can also contribute to inflationary pressures (Ajisafe et al., 2021).
