For insurance firms, underwriting and investment strategies are defined as the dollar weights allocated to underwriting activities (direct premium, net reinsurance, etc.) and the investment of assets respectively. Using a sample of 83 Canadian property-liability insurance companies for 1996 to 2010, we first examine the impact of underwriting and investment strategies on both the level and speed of insurers’ capital adjustment. Then, we investigate how these factors affect the solvency and profitability of Canadian property and casualty insurers. We find that the need to use retained earnings that have been accumulated in soft markets forces insurers to increase their profitability to withstand upcoming hard market conditions, triggering a new stage of the insurance cycle. In addition, we show that, in hard markets, when insurers are reluctant to take on new risk and when market power increases due to higher concentration, not only does the capital level decrease but so do profitability and solvency. Our observations, while suggesting the need for greater regulatory vigilance in hard markets, might support a through-the-cycle approach to monitoring capital adequacy based on the insurance cycle.
