1.1 Introduction
Inflation is defined as the persistent and general increase in the prices of goods and services over a period of time, resulting in a decline in the purchasing power of money (Samuelson & Nordhaus, 2018). It represents a key macroeconomic variable that affects almost every sector of the economy, including the insurance industry. In Nigeria, inflation has remained a recurring challenge that influences both the operational efficiency and financial stability of insurance firms. Insurance, by its very nature, involves predicting and managing future risks, and when inflation becomes unpredictable, it complicates the process of forecasting claim costs, setting premiums, and maintaining adequate reserves (Akinlo, 2019).
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
The relationship between inflation and insurance risk modeling has evolved over several decades, driven by changing economic conditions and advancements in actuarial science. Historically, the concept of insurance emerged as a mechanism for mitigating financial uncertainty and distributing risk across individuals and institutions. According to Rejda and McNamara (2019), modern insurance practices can be traced back to the 17th century in London, where merchants established Lloyd's of London as a hub for marine and trade insurance. As global financial systems expanded, insurers began developing mathematical and statistical models known as risk models to predict losses and determine premium levels (Rejda and McNamara, 2019).
Inflation remains one of the most significant macroeconomic challenges affecting the financial and insurance sectors globally. It is a sustained rise in the general price level of goods and services, leading to a reduction in the purchasing power of money and the real value of assets. According to Samuelson and Nordhaus (2018), inflation alters the stability of economic systems by distorting pricing mechanisms, interest rates, and investment decisions. In the insurance industry, such distortions undermine the accuracy of actuarial projections, premium pricing, and risk assessment models that rely on stable economic indicators.
Akinlo (2019) reported that inflation has a direct and indirect influence on insurance operations, particularly in the areas of claims management, underwriting, and solvency maintenance. He asserted that fluctuations in inflation rates lead to discrepancies between the expected and actual values of claims, thus making it difficult for insurers to maintain equilibrium between income from premiums and expenditures on claims. Eze and Okoye (2020) stated that inflation reduces the real value of premiums collected and increases the cost of claims settlement, thereby eroding profitability and threatening the financial sustainability of insurance firms in Nigeria.
Insurance risk models, which serve as essential tools for predicting and managing uncertainties, depend heavily on the accuracy of economic assumptions. Ojo (2021) affirmed that when inflation rises beyond projected levels, the assumptions embedded in these models such as constant interest rates and stable pricing trends become invalid. On the other hand, persistent inflation can increase operational expenses and reduce the real value of insurers' investment returns, thereby creating a mismatch between assets and liabilities.
Leadway Assurance Plc, one of Nigeria's leading insurance companies, provides a suitable case study for examining the impact of inflation on risk modeling. The company offers diverse insurance products life, property, motor, and health insurance each of which is susceptible to inflationary pressures. Nwankwo and Ezeani (2018) contended that in periods of high inflation, the cost of repairs, replacements, and medical expenses rises, leading to higher claim payouts than anticipated. Consequently, the company's actuarial estimates, pricing mechanisms, and reserve policies face increased volatility and uncertainty (Nwankwo et al., 2018).
Furthermore, the Nigerian economy has historically experienced fluctuating inflation rates due to unstable fiscal policies, exchange rate volatility, and dependency on imports. According to Akinlo (2019), such economic instability forces insurers to frequently adjust their models, often resulting in inefficiencies and increased exposure to financial risk. This study is set against the backdrop of the growing need to explore the relationship between inflationary trends and the accuracy of insurance risk modeling in Nigeria, using Leadway Assurance Plc as a case study.
1.3 Statement of Problems
Investigation revealed that the insurance industry relies heavily on actuarial models and risk forecasting tools to estimate future liabilities and determine appropriate premium rates. However, when inflation rises unexpectedly, these models tend to produce misleading results because the underlying assumptions of price stability and steady interest rates are violated. On the other hand, high inflation increases operational costs, erodes the real value of reserves, and weakens insurers' ability to meet long-term obligations to policyholders (Eze & Okoye, 2020).
Furthermore, inflation is not uniform across different sectors of the economy; medical inflation, for example, often grows faster than general inflation, thus making health-related insurance claims even more unpredictable. Similarly, inflationary pressures on property and motor insurance escalate the cost of repairs and replacements, which affects claims settlement ratios (Ojo, 2021). It is against this backdrop that this study seeks to evaluate the impact of inflation on insurance risk models with particular reference to Leadway Assurance Plc.
1.4 Purpose of the Study
The purpose of this study is to evaluate the impact of inflation on insurance risk models with a specific focus on Leadway Assurance Plc. The study seeks to examine how inflation affects pricing, reserve management, claims settlement, and overall financial performance. It also aims to assess the adequacy of current risk modeling practices and propose strategies for improving inflation sensitivity in actuarial and financial models.
