The Impact of Interest Rate Policy on Investment in Nigeria

Chapter One

1.1 Background of the Study
Interest rate policy plays a critical role in determining the level of investment in an economy. It influences borrowing costs, capital formation, and overall business confidence. Moreover, it serves as a key instrument of monetary policy for managing inflation and stimulating economic growth (Mishkin, 2021).

In Nigeria, the Central Bank sets the Monetary Policy Rate (MPR) to guide lending and deposit rates. Over the years, fluctuations in interest rates have affected private investment decisions. When rates are high, borrowing becomes expensive, discouraging business expansion. Conversely, when rates are low, investment tends to increase as credit becomes more affordable.

Furthermore, interest rate policy is influenced by macroeconomic conditions such as inflation, exchange rate stability, and fiscal balance. However, in Nigeria, inconsistent policies and structural weaknesses often distort the transmission of monetary decisions. Consequently, investors face uncertainty about future returns, which affects their willingness to commit long-term capital.

1.2 Statement of the Problem
Despite the Central Bank’s efforts to manage interest rates, investment levels in Nigeria remain low. Many firms struggle to access credit due to high lending rates and poor financial infrastructure. Moreover, policy uncertainty and inflationary pressures have further discouraged investment. Therefore, it is important to examine how interest rate policy influences investment in Nigeria.

1.3 Objectives of the Study
The main objective is to assess the impact of interest rate policy on investment in Nigeria.
Specific objectives are to:

1. Analyze the trend of interest rate policy in Nigeria.

2. Determine the relationship between interest rate changes and investment growth.

3. Identify factors that hinder effective interest rate management.

1.4 Research Questions

1.5 Significance of the Study
This study is significant because it enhances understanding of how monetary policy affects investment behavior. Furthermore, it provides insights for policymakers on designing interest rate frameworks that promote economic stability. In addition, it benefits researchers and students studying monetary economics.
