Effect of Claims Severity Trends on General Insurance Premium Adequacy

Abstract

Claims severity trends refer to changes in the average or distribution of claim amounts over time. In general insurance, increases in claim severity can arise from changes in repair costs, replacement values, medical expenses, inflation, legal costs, or the nature of insured losses. Monitoring these trends is important because changes in claim amounts can affect expected losses and the adequacy of premiums charged by insurers. The study examines the effect of claims severity trends on general insurance premium adequacy. It will assess how changes in the magnitude of insurance claims influence the ability of premium rates to sufficiently cover expected claims and associated insurance expenses. The study will also examine the relationship between claims severity trends, average claim amounts, loss experience, premium income, expected losses, and premium adequacy. The study will focus on claims severity trends, general insurance premium adequacy, claim amounts, expected losses, premium rates, premium income, claims experience, loss ratios, and insurance pricing. Actuarial pricing and loss modelling techniques will be applied to estimate expected claims under alternative severity trends. Comparative and sensitivity analyses will be used to determine the extent to which changes in claims severity affect the adequacy of general insurance premiums. A quantitative research approach will be adopted for the study. Relevant general insurance claims and premium data, including claim amounts, claim frequencies, premium income, exposure levels, loss ratios, policy periods, and historical claims experience, will be analysed. Descriptive statistics, severity trend analysis, frequency and severity modelling, loss ratio analysis, actuarial premium calculations, trend analysis, scenario analysis, and sensitivity analysis will be used to evaluate the effect of claims severity trends on premium adequacy. The study is expected to reveal that claims severity trends may have a significant effect on general insurance premium adequacy. Increasing claim severity may raise expected losses and reduce the ability of existing premium rates to cover future claims and related expenses, while stable or declining severity trends may produce different premium adequacy outcomes. The magnitude of the effect may depend on the rate of change in claim amounts, claim frequency, exposure levels, inflation, policy characteristics, and existing premium rates. The study is expected to be useful to actuaries, general insurance companies, underwriters, pricing analysts, claims managers, and financial managers. The findings may support premium review, loss forecasting, pricing adequacy assessment, reserve planning, risk management, and financial decision-making. The study may also assist insurers in identifying changes in claims severity that could require adjustments to premium rates and pricing assumptions. The study concludes that claims severity trends are important considerations in maintaining adequate general insurance premiums because changes in claim amounts can materially influence expected loss costs. It is therefore recommended that insurers regularly monitor claims severity trends, update pricing assumptions using recent claims experience, and conduct sensitivity analysis to assess whether existing premium rates remain adequate under alternative severity scenarios.
