THE RELATIONSHIP BETWEEN INTEREST RATE AND INVESTMENT DECISIONS IN THE NIGERIAN ECONOMY

THE RELATIONSHIP BETWEEN INTEREST RATE AND INVESTMENT DECISIONS IN THE NIGERIAN ECONOMY

CHAPTER ONE

1.1 Background of the Study

Investment remains a critical engine for economic growth and development in every nation. It enhances productive capacity, creates employment, and stimulates technological advancement. However, the level of investment in an economy often depends on the prevailing interest rate. Interest rate represents the cost of borrowing and the return on savings, and it plays a vital role in influencing the decisions of investors, both local and foreign (Jhingan, 2019).

In Nigeria, the relationship between interest rate and investment has been a topic of great concern. The economy has experienced frequent fluctuations in interest rates due to monetary policy adjustments, inflation, and exchange rate instability. According to the Central Bank of Nigeria (2023), lending rates have remained relatively high, discouraging private investment and business expansion. Consequently, investors often find it difficult to access credit for productive ventures.

An increase in interest rate tends to raise the cost of borrowing, thereby reducing the volume of investment. Conversely, when interest rates fall, businesses are more likely to invest because loans become cheaper. This interaction between interest rate and investment decisions lies at the heart of monetary policy transmission. Although the Central Bank of Nigeria implements monetary policy to control inflation and stabilize the economy, the unintended consequence can sometimes be reduced private sector investment.

Over the years, the Nigerian government has made several efforts to encourage investment through fiscal incentives, development finance schemes, and lower interest loans for priority sectors. Despite these measures, investment growth remains sluggish compared to the needs of a developing economy. The inconsistency in monetary policy, poor infrastructure, and rising inflation continue to hinder the flow of investment. Therefore, this study examines the relationship between interest rate and investment decisions in Nigeria, focusing on how interest rate dynamics affect economic performance.

1.2 Statement of the Problem

The Nigerian economy has continued to experience wide fluctuations in interest rates, which in turn have influenced investment behavior. High and unstable lending rates have discouraged borrowing by small and medium-sized enterprises (SMEs), leading to reduced capital formation and slower growth. Furthermore, uncertainty in the financial system and inconsistent policy measures have weakened investor confidence.

Despite the Central Bank’s efforts to maintain a stable interest rate regime, the gap between deposit and lending rates remains wide. Many productive firms face difficulties in accessing credit, which limits their capacity to expand. As a result, the country experiences low industrial growth, unemployment, and reduced competitiveness.

This situation raises important questions about the extent to which interest rate variations influence investment decisions in Nigeria. Understanding this relationship is crucial for designing effective monetary and fiscal policies that encourage investment and sustain economic growth.

1.3 Objectives of the Study

The main objective of this study is to examine the relationship between interest rate and investment decisions in the Nigerian economy. The specific objectives are to:

1. Analyze the trend of interest rate and investment in Nigeria from 2010 to 2024.

2. Examine the effect of interest rate changes on private sector investment.

3. Assess the influence of monetary policy on investment decisions in Nigeria.

4. Identify challenges that hinder investment growth in relation to interest rate dynamics.

1.4 Research Questions

The following research questions will guide the study:

1. What has been the trend of interest rate and investment in Nigeria between 2010 and 2024?

2. How do changes in interest rate affect private sector investment?

3. What role does monetary policy play in influencing investment decisions?

4. What factors hinder investment growth in Nigeria?

1.5 Hypotheses of the Study

The study will test the following hypotheses:

• H₀: Interest rate has no significant relationship with investment decisions in the Nigerian economy.

• H₁: Interest rate has a significant relationship with investment decisions in the Nigerian economy.

1.6 Significance of the Study

This study is valuable for policymakers, financial institutions, investors, and researchers. For policymakers, it provides insights into how interest rate management can stimulate private investment and enhance economic growth. It also highlights the importance of maintaining a balance between inflation control and investment promotion.

For financial institutions, the study offers a better understanding of how lending rate decisions affect credit demand and business performance. Investors will also benefit from knowing how interest rate fluctuations influence capital allocation and risk assessment.

For researchers and students, the study contributes to the literature on monetary policy and investment behavior in developing economies. It provides empirical evidence that supports policy formulation and economic planning in Nigeria.

1.7 Scope of the Study

This study focuses on the Nigerian economy and covers the period from 2010 to 2024. It examines trends in interest rate, investment levels, and economic performance indicators such as GDP growth, inflation rate, and gross capital formation. The research will rely on secondary data obtained from the Central Bank of Nigeria (CBN), National Bureau of Statistics (NBS), and World Bank reports.
