The insurance sector is an essential component for the continued expansion and prosperity of the economy. It is the responsibility of the insurance industry to secure the continued existence of enterprises, to disperse the risk that is caused by financial losses, and to work toward eradicating uncertainty in the minds of investors. Despite the important role of the insurance sector in the economy, firms operating in this sector have been having trouble maintaining their financial stability. The insurance sector has faced considerable volatility in profitability, resulting in some firms being placed under receivership or even going out of firm. The purpose of this study was to analyse the effect of loss ratio on financial stability of insurance firms in Kenya. The study was anchored on the Theory of Distress by Wreckers. The research was conducted using an explanatory research design, and the positivist philosophical approach was utilized. The target population for this study consisted of the 46 insurance firms that held IRA licenses and were operating during the time period under consideration (2014-2021). The census method was utilized for the research thesis, which focused on all 46 insurance firms in Kenya. The study used secondary data obtained from audited financial statements, which were publicly available on the websites of individual insurance firms. To gather panel data for the study, a secondary data collection template was employed. In order to draw conclusions from the data that was gathered, this study employed both descriptive and inferential statistical methods. The study employed a generalized method of moments modelling guided by static panel regression. The data processing was done using the Stata software. The research findings were presented through the use of tables and trend line graphs. The study adhered to research ethics guidelines. The findings of this study showed that loss ratio had a significant negative influence on the financial stability of Kenyan insurance companies (β = -0.5795373, p = 0.002 < .05).The study concludes that loss ratios and capital adequacy plays a significant role in the financial stability of insurance firms. A lower loss ratio indicates a more efficient underwriting process and risk management, contributing to better financial performance and stability. As a result, the study recommends that to enhance their financial stability, general insurers in Kenya should manage their loss ratio. It's also recommended that Kenya should adhere to the principles of the Solvency II framework. Keywords: Loss Ratio, Insurance Firms, Claims Management, Financial Stability, Kenya
