1.1 Introduction
Interest rate refers to the cost of borrowing money expressed as a percentage of the principal amount over a specified period. It represents the price paid by borrowers for the use of funds provided by lenders and serves as a critical instrument in financial transactions and credit administration. In the banking sector, interest rates influence borrowing decisions, investment activities, savings behavior, and loan repayment performance. The level of interest charged on loans is often determined by factors such as inflation, monetary policy, operational costs, market conditions, and the perceived risk associated with lending activities (Mishkin, 2022).
Microfinance banks are specialized financial institutions established to provide financial services, particularly credit facilities, savings products, and other banking services, to low-income individuals, microenterprises, and small-scale business operators who are often excluded from the conventional banking system. In Nigeria, microfinance banks have become important vehicles for promoting financial inclusion, reducing poverty, enhancing entrepreneurship, and supporting economic development (Central Bank of Nigeria, 2021).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Interest rates and loan repayment are among the most important issues in the operations of financial institutions across the world. Interest rate refers to the amount charged by a lender to a borrower for the use of borrowed funds, usually expressed as a percentage of the principal amount over a specified period. Loan repayment, on the other hand, refers to the process through which borrowers fulfill their financial obligations by paying back the principal amount borrowed together with the agreed interest within a specified timeframe. The relationship between interest rates and loan repayment has attracted significant attention among scholars, policymakers, and financial practitioners because of its implications for financial stability, credit accessibility, and economic development.
According to Mishkin (2022), interest rates serve as a fundamental mechanism for allocating financial resources within an economy and significantly influence borrowing and lending decisions. Financial institutions rely on interest income as a major source of revenue, while borrowers consider lending rates when making decisions regarding investments and business expansion. The level of interest charged on loans often determines the affordability of credit and the capacity of borrowers to meet repayment obligations. Consequently, changes in interest rates may have significant effects on loan repayment performance and the sustainability of lending institutions.
Microfinance banking emerged as a response to the inability of conventional financial institutions to adequately serve low-income individuals and small-scale entrepreneurs. According to the Central Bank of Nigeria (2021), microfinance banks were established to provide financial services to economically active poor individuals, microenterprises, and small businesses that lack access to traditional banking facilities. These institutions have become important instruments for promoting financial inclusion, poverty reduction, entrepreneurship development, and economic growth in developing countries, including Nigeria.
Armendáriz and Morduch (2010) asserted that microfinance institutions were established to bridge the financial gap created by the exclusion of low-income earners from mainstream banking systems. Through the provision of credit facilities, savings opportunities, and other financial services, microfinance institutions contribute to income generation and improved living standards among borrowers. The effectiveness of these institutions, however, depends largely on the successful recovery of loans granted to customers.
Ledgerwood (2013) stated that timely loan repayment ensures the continuous availability of funds for lending activities, enhances institutional profitability, and supports long-term financial sustainability. When borrowers fail to repay loans as agreed, microfinance banks experience increased levels of non-performing loans, liquidity constraints, and financial losses. Such situations may undermine the ability of these institutions to provide financial services to other prospective borrowers and achieve their developmental objectives.
Interest rates play a significant role in determining the repayment capacity of borrowers. Mishkin (2022) reported that borrowing costs influence investment decisions, business performance, and the ability of borrowers to meet financial commitments. In many developing economies, including Nigeria, microfinance banks often charge relatively higher interest rates compared to conventional banks because of the high operational costs associated with serving numerous small-scale borrowers. These costs include loan administration, monitoring, risk management, and transaction expenses. While higher interest rates may help institutions cover operating costs and remain financially viable, they may also increase the repayment burden on borrowers.
The Nigerian economy has experienced several macroeconomic challenges over the years, including inflationary pressures, exchange rate fluctuations, unemployment, and economic instability. According to the Central Bank of Nigeria (2023), these economic conditions have affected the cost of funds available to financial institutions and influenced lending practices within the banking sector. As operating costs continue to rise, many microfinance banks adjust their lending rates upward to maintain profitability and cover associated risks. This situation has raised concerns regarding the affordability of loans and the capacity of borrowers to repay their obligations.
Rosenberg, Gonzalez, and Narain (2013) reported that high microcredit interest rates often create financial pressure on borrowers, especially those operating small businesses with unstable income streams. When a substantial portion of business earnings is devoted to servicing debt, borrowers may encounter difficulties meeting repayment schedules. This challenge becomes more pronounced during periods of economic downturn, declining business performance, or unexpected financial shocks. As a result, loan delinquency and default rates may increase, thereby affecting the financial health of lending institutions.
This study is set against the backdrop of increasing concerns regarding loan repayment challenges among microfinance bank customers in Nigeria, rising lending rates within the financial sector, and the need to ensure sustainable microfinance operations that support economic development and financial inclusion.
1.3 Statement of Problems
Investigation revealed that excessive lending rates are associated with poor loan repayment performance and increased credit risk among financial institutions (Armendáriz & Morduch, 2010; Rosenberg et al., 2013). In Nigeria, fluctuations in macroeconomic conditions such as inflation, exchange rate instability, rising operating costs, and changes in monetary policies have contributed to variations in lending rates among microfinance banks. These conditions have led many microfinance institutions to charge relatively high interest rates in order to cover administrative expenses and credit risks. Consequently, many borrowers struggle to meet repayment obligations, thereby affecting the quality of loan portfolios and reducing the capacity of microfinance banks to extend credit to other prospective clients (CBN, 2023).
Furthermore, the persistent occurrence of loan defaults has continued to pose serious concerns for microfinance institutions, resulting in reduced profitability, liquidity challenges, and increased operational risks. If this situation persists, the ability of microfinance banks to achieve their objectives of financial intermediation and poverty alleviation may be adversely affected. It is against this backdrop that this study seeks to examine the effect of interest rates on loan repayment in microfinance banks in Nigeria.

1.8 Scope of Study
The study examines the effect of interest rates on loan repayment in microfinance banks in Nigeria, using LAPO Microfinance Bank in Lagos State as the case study. The research focuses on interest rates, loan repayment performance, loan defaults, borrowers' repayment obligations, and non-performing loans.
The study was limited by restricted access to some confidential financial records of the organization.
