1.0 Introduction
1.1 Background of Study
The money supply in an economy plays a pivotal role in shaping its economic landscape, influencing everything from inflation rates to overall economic growth. In Nigeria, a developing nation with a dynamic and often volatile economy, the interaction between macroeconomic factors and the money supply is particularly crucial. Understanding this relationship is essential for policymakers, economists, and stakeholders to navigate the complexities of the Nigerian economic environment and to implement effective monetary policies.
Macroeconomic factors, such as inflation, interest rates, exchange rates, and government fiscal policies, significantly impact the money supply. In Nigeria, these factors are interconnected in ways that reflect both global economic trends and domestic economic policies. For instance, inflation rates can influence the Central Bank of Nigeria's (CBN) decisions regarding interest rates and money supply management. High inflation may prompt the CBN to tighten the money supply to stabilize the economy, while low inflation might encourage an expansionary monetary policy.
Since the 1990s, Nigeria has experienced periods of economic growth and contraction, driven by domestic and external factors. Studies during these times have explored how macroeconomic variables such as inflation, fiscal policies, GDP growth, and financial sector reforms impact money supply stability and economic performance. Nigeria's economy is predominantly oil-dependent, with fluctuations in global oil prices impacting government revenues and foreign exchange earnings. This dependency underscores the vulnerability of the economy to external shocks and emphasizes the importance of effective macroeconomic management in stabilizing economic performance.
According to Ajisafe and Folorunso (2011), Nigeria has experienced periods of high inflation and exchange rate volatility, which have significant implications for money supply dynamics. The Central Bank of Nigeria (CBN) plays a crucial role in managing these challenges through monetary policy interventions aimed at maintaining price stability and ensuring adequate liquidity in the financial system. Furthermore, fiscal policies, including government spending and taxation, influence economic growth rates and money supply conditions. Effective fiscal management is essential for supporting sustainable development and mitigating inflationary pressures. The financial sector in Nigeria has undergone reforms aimed at enhancing stability and improving the efficiency of financial intermediation. These reforms have implications for how monetary policy actions translate into changes in money supply and economic activity.
Over the decades, various economic crises and policy shifts have influenced the study of macroeconomic factors on money supply. The oil boom of the 1970s led to significant revenue inflows but also exposed the economy to fluctuations in global oil prices. This period highlighted the need for effective monetary and fiscal policies to manage oil revenue volatility and stabilize the economy.
The Structural Adjustment Program (SAP) in the 1980s introduced market-oriented reforms aimed at liberalizing the economy, reducing government intervention, and promoting private sector growth. These reforms had implications for monetary policy and money supply dynamics, emphasizing the role of the Central Bank of Nigeria (CBN) in managing inflation and stabilizing the exchange rate. Today, the study of macroeconomic factors on money supply in Nigeria continues to be relevant as policymakers and researchers navigate challenges such as inflation management, exchange rate stability, and economic diversification. Therefore, in Nigeria where the research was carried out, the activities that was conducted is to know the impact of macroeconomic factor on money supply in Nigeria.
1.2 Statement of Problems
Investigation revealed that inflation in Nigeria significantly affects the stability and growth of money supply, impacting economic stability and policy effectiveness (Ajisafe & Folorunso, 2011). Exchange rate fluctuations pose challenges to maintaining stable money supply conditions, influencing the Central Bank's ability to manage liquidity effectively (Iheonu, 2017). Fiscal policies, including government spending and taxation, play a crucial role in shaping money supply dynamics and economic stability (Olaniyan & Omotesho, 2015).
GDP growth rates affect the aggregate demand for money, highlighting the importance of economic expansion in shaping monetary conditions (Nwachukwu & Enoma, 2018). Financial sector reforms, such as banking sector consolidation and regulatory changes, impact the efficiency and effectiveness of monetary policy transmission mechanisms (Ogundipe & Ojeaga, 2012). Hence, it is against this backdrop that this study aims to examine the impact of macroeconomic factor on money supply in Nigeria.
1.3 Aim and Objectives of Study
