CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Inflation, generally defined as a sustained rise in the general price level of goods and services over time, is regarded as one of the fundamental risks confronting economies and institutions, including insurance companies, because virtually everyone in society is affected by it. In the insurance industry, inflation has a two-sided influence: it erodes the real value of fixed premiums and long-term liabilities, while at the same time it may allow insurers to adjust premium rates upward, at least for products that are not tariffed (Chilekezi, 2024).

Persistent high inflation has been shown to constrain the growth of the life insurance segment of the Nigerian insurance industry in particular, because life products compete with other savings and investment vehicles whose real returns are more sensitive to inflationary erosion (Epetimehin & Fatoki, 2011). Nigeria has, over the past decade, experienced periods of elevated inflation driven by exchange rate depreciation, fuel price adjustments and structural supply-side constraints, all of which raise the cost of settling claims, particularly for classes of business such as motor and fire insurance, where claim costs are closely tied to the price of imported spare parts, building materials and other inputs.

Where claims inflation outpaces the rate at which premiums are repriced, insurers may experience a widening loss ratio and pressure on solvency margins even in years of rising nominal premium income. Industry data show that the non-life segment's incurred loss ratio moved from about 47.7 per cent to 45.0 per cent, and then to roughly 41 per cent, over the three most recent reporting periods, reflecting the sensitivity of underwriting results to changes in the cost environment (National Insurance Commission, 2023). Given the significance of premium adequacy to insurer solvency, and the sustained inflationary pressure in the Nigerian economy, there is a continuing need to examine, with updated data, how inflation affects the level and adequacy of insurance premiums in Nigeria.

1.2 Statement of the Problem

Nigerian insurers operate in an economy characterised by persistent and, at times, volatile inflation, yet the empirical evidence on how this inflation translates into changes in insurance premiums remains mixed: some studies find a significant long-run relationship between inflation and insurance operations (Chilekezi, 2024), while others report that inflation does not significantly affect certain measures of non-life sector performance. This inconsistency, combined with the practical difficulty many Nigerian insurers face in adjusting premium rates promptly for non-tariffed products in response to rising costs, creates a risk that premiums become inadequate to cover the real cost of future claims, undermining insurer solvency and policyholder protection. This study seeks to re-examine, with current data, the impact of inflation on insurance premiums in Nigeria in order to provide clearer evidence for pricing and regulatory decisions.

1.3 Objectives of the Study

The main objective of this study is to examine the impact of inflation on insurance premiums in Nigeria. The specific objectives are to:

i. examine the trend of inflation and insurance premium income in Nigeria over the study period;

ii. determine the effect of inflation on the gross premium income of insurance companies in Nigeria;

iii. assess the extent to which inflation influences the loss ratio and claims cost of insurers; and

iv. recommend pricing and regulatory strategies for mitigating the adverse effects of inflation on insurance business in Nigeria.

1.4 Research Questions

The study is guided by the following research questions:

1. What is the trend of inflation and insurance premium income in Nigeria over the study period?

2. What effect does inflation have on the gross premium income of insurance companies in Nigeria?

3. To what extent does inflation influence the loss ratio and claims cost of insurers?

4. What pricing and regulatory strategies can mitigate the adverse effects of inflation on insurance business in Nigeria?

1.5 Research Hypotheses

The following null hypotheses are formulated to guide the study:

H01: Inflation has no significant effect on the gross premium income of insurance companies in Nigeria.

H02: Inflation has no significant effect on the loss ratio of insurance companies in Nigeria.

1.6 Significance of the Study

This study will benefit insurance companies by providing evidence to guide premium-repricing and product-design decisions in an inflationary environment. It will assist the National Insurance Commission and other regulators in assessing the adequacy of premium rates and in formulating policy responses that protect both insurer solvency and policyholder interests. Policymakers concerned with the broader relationship between monetary conditions and financial-sector stability will find the findings relevant to macro-prudential oversight of the insurance sector. The study will also add to the Nigerian literature on inflation and insurance performance and will be useful to students and researchers in insurance, economics and finance.

1.7 Scope and Limitation of the Study

The study covers the relationship between inflation, proxied by the Consumer Price Index or the inflation rate, and insurance premiums and related performance indicators in Nigeria, using secondary time series data obtained from the Central Bank of Nigeria and the National Insurance Commission over a defined period. The study is limited to the specific inflation and premium or claims proxies and period selected, and by any inconsistencies in the underlying published statistics.

1.8 Definition of Terms

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

Insurance Premium: The amount paid by a policyholder to an insurer in exchange for insurance cover.

Gross Premium Income: The total premium income received by an insurer before deducting reinsurance costs.

Consumer Price Index (CPI): A measure of the average change in prices paid by consumers for a basket of goods and services, commonly used as a proxy for inflation.

Loss Ratio: The ratio of incurred claims to earned premium.

Non-tariffed Products: Insurance products for which premium rates are not fixed by regulation and can be adjusted by insurers.

Solvency: The ability of an insurer to meet its long-term financial obligations, including claims liabilities.

Underwriting Profit: The profit made by an insurer from its core insurance operations, before investment income.

Real Value: The value of money or an asset after adjusting for the effects of inflation.

Claims Cost: The total cost incurred by an insurer in settling claims, including the amounts paid to claimants and associated expenses.
