1.0 Introduction
1.1 Background of Study
Nigeria's exchange rate history has been marked by frequent fluctuations, largely due to its heavy dependence on crude oil exports. The Structural Adjustment Program (SAP) introduced in 1986 shifted the country from a fixed exchange rate system to a market-driven mechanism, leading to increased volatility (Mordi, 2006). Fluctuations in the exchange rate can have significant consequences on economic growth. Exchange rate plays a crucial role in the economic stability and growth of any nation, particularly in developing economies like Nigeria, where foreign trade and external financial transactions significantly influence economic activities. According to Dornbusch (1980), the exchange rate serves as a key determinant of international competitiveness, influencing trade balances, inflation, and capital flows. Exchange rate fluctuations, therefore, have both direct and indirect effects on a nation's economic performance.
Nigeria's exchange rate history has been marked by frequent fluctuations, largely due to its heavy dependence on crude oil exports. The Structural Adjustment Program (SAP) introduced in 1986 shifted the country from a fixed exchange rate system to a market-driven mechanism, leading to increased volatility (Mordi, 2006). However, the persistent depreciation of the naira, coupled with external shocks such as global oil price declines, has contributed to macroeconomic instability. Fluctuations in the exchange rate can have significant consequences on economic growth. As highlighted by Adebiyi and Dauda (2009), a depreciating currency can lead to higher import costs, rising inflation, and reduced purchasing power, thereby affecting overall economic productivity. Conversely, a well-managed exchange rate policy can enhance foreign direct investment, improve trade balance, and support long-term economic growth.
Exchange rate fluctuation refers to the continuous changes in the value of one currency relative to another in the foreign exchange market. According to Krugman and Obstfeld (2003), exchange rate fluctuation occurs due to variations in demand and supply conditions, inflation rates, interest rates, and other macroeconomic indicators. In an economy like Nigeria, where foreign trade plays a significant role in economic activities, exchange rate movements can have profound effects on economic growth (Krugman and Obstfeld, 2003). Nigeria, being an oil-dependent economy, is highly susceptible to exchange rate volatility, primarily due to fluctuations in global crude oil prices. As noted by Mordi (2006), exchange rate instability affects various macroeconomic variables, including inflation, investment, and trade balance, which in turn impact economic growth. Over the years, Nigeria has experienced significant exchange rate variations, especially after the introduction of the Structural Adjustment Program (SAP) in 1986, which led to the adoption of a market-driven exchange rate system.
Therefore, this study seeks to analyze the impact of exchange rate fluctuation on Nigeria's economic growth by examining key macroeconomic indicators such as Gross Domestic Product (GDP), inflation, trade balance, and investment inflows.
1.2 Statement of Problems
Investigation revealed that the Nigerian economy has experienced periods of rapid currency depreciation, especially after the implementation of the Structural Adjustment Program (SAP) in the mid-1980s, when the country moved from a fixed exchange rate system to a market-determined exchange rate system. The exchange rate volatility has also led to rising costs of imports, exacerbating inflationary pressures, which in turn affect the overall standard of living. While there have been efforts by the Central Bank of Nigeria (CBN) to stabilize the exchange rate through various monetary policies and interventions, the effect of these fluctuations on key economic indicators such as GDP growth, investment inflows, and the trade balance remains unclear.
Furthermore, the persistent challenge of managing exchange rate instability is hindering Nigeria's ability to achieve sustainable economic growth. This research seeks to investigate the full extent of exchange rate fluctuations on Nigeria's economic growth and explore how these variations affect economic performance, with the aim of providing insights for policymakers on how to mitigate the negative impact.
1.3 Aim and Objectives of Study
The aim of this study is to examine the impact of exchange rate fluctuations on Nigeria's economic growth. In achieving this aim, the following specific objectives were laid out as follows:

1.5 Research Hypothesis
In order to pursue the objective of this study, the following generalized statements have been designed to guide and aids in obtaining the result for the experiment to be conducted. For this work, the null hypothesis will be represented with H0 while the alternative hypothesis will be represented with hypothesis H1.
- H0: There is no significant relationship between exchange rate fluctuations and Nigeria's economic growth, and exchange rate volatility does not have a meaningful impact on GDP, inflation, foreign direct investment (FDI), trade balance, or economic stability.
- H1: There is a significant relationship between exchange rate fluctuations and Nigeria's economic growth, with exchange rate volatility affecting GDP, inflation, foreign direct investment (FDI), trade balance, and overall economic stability.
1.6 Significance of Study
The outcome of this research will contribute to the existing body of knowledge by providing a deeper understanding of how exchange rate fluctuations impact Nigeria's economic growth. Also, this will support the development of more effective monetary and fiscal policies aimed at mitigating the adverse effects of exchange rate volatility.
Furthermore, the study will inform future economic planning and decision-making, providing guidance on how to manage exchange rate fluctuations to promote economic stability and attract foreign investment.
Lastly, academics and researchers will benefit from the study as it will add to the existing literature on the relationship between exchange rate fluctuations and economic growth in developing economies. The research findings will serve as a foundation for future studies and provide a comprehensive analysis for further exploration.
1.7 Scope of Study
This study will focus on examining the impact of exchange rate fluctuations on Nigeria's economic growth, specifically within the context of Lagos State, one of Nigeria's largest and most economically significant states. The study will cover the period from 2000 to 2023, a timeframe that encompasses various phases of exchange rate policy changes in Nigeria, including the shift from a fixed to a floating exchange rate system and subsequent fluctuations due to global economic factors.
1.8 Limitations of the Study
The study was limited by time constraints. The research period covered was from 2000 to 2023, but the analysis of exchange rate fluctuations and their impact on economic growth was influenced by short-term events or global economic crises that were not fully captured within this timeframe.
Additionally, there were external factors outside of exchange rate fluctuations that affected Nigeria's economic growth, such as oil price volatility, political instability, and global economic conditions.
Lastly, limitations were also found in accessing some primary data from businesses and organizations in Lagos, as some stakeholders were reluctant to share sensitive information regarding the impact of exchange rate fluctuations on their operations, which could have enriched the study.
1.9 Definition of Terms
Exchange Rate:
Exchange rate refers to the value of one currency in terms of another. It indicates how much of a foreign currency can be exchanged for a unit of the domestic currency. In Nigeria, the exchange rate is influenced by various factors such as global market conditions, oil prices, and government policies. Exchange rate fluctuations occur when there is a significant change in the value of the naira relative to other major currencies like the US dollar or the euro (Oyejide, 2007).
Exchange Rate Fluctuation:
Exchange rate fluctuation refers to the continuous changes in the value of a currency in response to market forces, economic policies, and other external factors. In the context of Nigeria, fluctuations in the exchange rate often result from global oil price changes, political instability, and shifts in demand for the naira (Adebiyi & Dauda, 2009).
Economic Growth:
Economic growth refers to the increase in the value of goods and services produced by an economy over time, typically measured by the growth in Gross Domestic Product (GDP). In the case of Nigeria, economic growth is influenced by various factors, including fiscal policies, industrialization, inflation rates, and exchange rate stability. Sustainable economic growth is crucial for improving living standards, creating jobs, and reducing poverty (Mordi, 2006).
Gross Domestic Product (GDP):
GDP is the total monetary value of all finished goods and services produced within a country's borders during a specific period, typically a year or a quarter. It serves as a comprehensive measure of a country's overall economic output. In Nigeria, fluctuations in exchange rates can directly affect the GDP by influencing the cost of imports, export competitiveness, and inflation rates, which in turn impact economic growth (Oyejide, 2007).
Inflation:
Inflation refers to the rate at which the general level of prices for goods and services rises, eroding purchasing power. In Nigeria, exchange rate fluctuations often contribute to inflation, especially when the value of the naira depreciates against foreign currencies, leading to increased import costs. This can result in higher prices for everyday goods and services, affecting the standard of living (Mordi, 2006).
Foreign Direct Investment (FDI):
FDI refers to investments made by foreign entities or individuals in the businesses, infrastructure, or assets of another country. For Nigeria, FDI plays a vital role in stimulating economic growth by creating jobs, improving technological transfer, and boosting the country's industrial capabilities. Exchange rate volatility, however, can discourage foreign investors due to uncertainties surrounding currency devaluation and profitability (Adebiyi & Dauda, 2009).
