The Impact of Inflation on Economic Growth in Nigeria (2010–2024)

THE IMPACT OF INFLATION ON ECONOMIC GROWTH IN NIGERIA (2010–2024)

CHAPTER ONE

1.1 Background of the Study

Inflation is one of the most persistent macroeconomic problems facing developing economies, including Nigeria. It is often regarded as a situation where too much money chases too few goods, leading to a continuous rise in the general price level of goods and services (Samuelson and Nordhaus, 2015). A moderate rate of inflation is considered normal in a growing economy, but when it rises beyond control, it erodes purchasing power, reduces savings, and discourages investment.

In Nigeria, inflation has been a recurring economic challenge since the early 1980s. Structural factors such as dependence on oil exports, weak industrial production, poor infrastructure, and unstable exchange rates have contributed to price instability. Over the years, the country has witnessed different phases of inflation driven by government expenditure, monetary policy changes, fuel price hikes, and foreign exchange crises.

Economic growth, measured by changes in Gross Domestic Product (GDP), reflects the overall health of an economy. It is influenced by several factors including inflation, investment, fiscal policy, and trade performance. While some economists argue that mild inflation can stimulate growth by encouraging production and investment, others contend that high and unpredictable inflation discourages savings and distorts resource allocation (Fischer, 1993).

Between 2010 and 2024, Nigeria experienced varying inflation rates ranging from single digits to double digits, largely due to fluctuations in global oil prices, exchange rate depreciation, and insecurity affecting food production. Despite several monetary and fiscal interventions by the Central Bank of Nigeria (CBN), inflation continues to threaten macroeconomic stability. Therefore, it is important to examine how inflation has affected Nigeria’s economic growth over this period.

1.2 Statement of the Problem

Persistent inflation remains a major obstacle to Nigeria’s economic growth. Although the government and the Central Bank have implemented various monetary and fiscal measures to control inflation, the rate has continued to rise. The frequent increases in fuel prices, food shortages due to insecurity, and foreign exchange instability have made inflation a permanent feature of the Nigerian economy.

Despite moderate GDP growth in some years, high inflation has weakened the real value of income, reduced consumer purchasing power, and discouraged long-term investment. The continuous rise in prices also affects the cost of production, reduces competitiveness, and contributes to unemployment. The relationship between inflation and economic growth in Nigeria therefore remains complex and uncertain.

This study seeks to analyze the extent to which inflation has influenced Nigeria’s economic growth between 2010 and 2024, identifying whether inflation has a positive, negative, or insignificant effect on the economy.

1.3 Objectives of the Study

The main objective of this study is to examine the impact of inflation on economic growth in Nigeria between 2010 and 2024. The specific objectives are to:

1. Analyze the trend of inflation and economic growth in Nigeria from 2010 to 2024.

2. Examine the relationship between inflation and Gross Domestic Product (GDP) growth in Nigeria.

3. Determine the effect of inflation on investment and productivity in the Nigerian economy.

4. Evaluate the policy measures adopted by the Central Bank of Nigeria to control inflation.

1.4 Research Questions

The following research questions will guide the study:

1. What has been the trend of inflation and economic growth in Nigeria between 2010 and 2024?

2. What is the relationship between inflation and economic growth in Nigeria?

3. How does inflation affect investment and productivity in Nigeria?

4. How effective have the policies of the Central Bank of Nigeria been in controlling inflation?

1.5 Hypotheses of the Study

The study will test the following hypotheses:

• H₀: Inflation has no significant impact on economic growth in Nigeria.

• H₁: Inflation has a significant impact on economic growth in Nigeria.

1.6 Significance of the Study

This study holds relevance for policymakers, researchers, and economic planners. It offers evidence-based insights into the relationship between inflation and economic growth, enabling policymakers to design more effective macroeconomic policies. Researchers and students will find value in its contribution to the growing body of literature on inflation dynamics within developing economies.

The findings also provide economic planners and financial institutions with a clearer understanding of how inflation influences investment decisions and production output. Such knowledge can support the formulation of strategies that promote price stability, encourage productive investment, and foster sustainable economic growth.

1.7 Scope of the Study

This study focuses on the Nigerian economy between 2010 and 2024. It will analyze secondary data on inflation and GDP growth rates obtained from sources such as the Central Bank of Nigeria (CBN), National Bureau of Statistics (NBS), and World Bank reports. The study will limit its analysis to macroeconomic indicators directly related to inflation and growth, including investment, interest rates, and exchange rates.

1.8 Definition of Key Terms

Inflation: A persistent increase in the general price level of goods and services in an economy over a period of time.

Economic Growth: An increase in the productive capacity and real output of a country as measured by Gross Domestic Product (GDP).

Monetary Policy: The actions of the Central Bank aimed at controlling money supply, credit, and interest rates to achieve economic stability.

Gross Domestic Product (GDP): The total monetary value of all goods and services produced within a country’s borders during a specific period.

Price Stability: A condition where prices in an economy do not fluctuate significantly, ensuring stable purchasing power.
