General Insurance Risk Margin Statistics - June 2025

General insurance

The valuation of insurance liabilities is an important aspect of the general insurance regulatory framework. The provisions determined as a result of these valuations have a direct impact on the financial soundness of the insurer, and the insurer’s ability to protect the interests of policy holders who have put their trust in it. It is therefore important that insurance liabilities, including risk margins and diversification benefits, are valued in an appropriate manner.

The risk margin allows for the risk that outcomes will differ from the central estimate of the insurance liabilities, both because of the inherent uncertainty of the distribution of possible outcomes, and because of the randomness of future outcomes. It will usually include an allowance for the variability of claims experience within a class of business (stand-alone risk margin) and also a deduction for any diversification between classes of business (diversification benefit). Together the central estimate and the risk margin are intended to produce a provision for insurance liabilities that will prove to be sufficient to pay claims as they fall due 75 per cent of the time. This 75 per cent probability of sufficiency level is the sufficiency level required by APRA.

This report provides a detailed summary of the risk margins adopted by insurers for varying classes of business. The role of the report is not to prescribe particular risk margins, but rather to give some insight into the range of risk margins currently adopted by industry. APRA uses the information provided here for benchmarking and for checking on the risk margins adopted by individual insurers. Actuaries may similarly find this information useful.

Charts

1. OCL Risk Margins for Direct Business

This chart shows the quartiles as well as the weighted mean of the outstanding claim liabilities stand-alone risk margin by direct business class.

For some classes, there are too few insurers to allow the weighted average and/or quartile range to be shown.

Horizontal bar chart showing risk margin percentages by direct insurance class. Dark and light bars show quartiles, with orange diamonds for weighted means across categories.

2. PL Risk Margins for Direct Business

This chart shows the quartiles as well as the weighted mean of the premium liabilities stand-alone risk margin by direct business class.

For some classes, there are too few insurers to allow the weighted average and/or quartile range to be shown.

Horizontal bar chart of premium liability risk margins by direct insurance class. Quartiles shown as bars and weighted means as orange markers, with variation across categories.

3. OCL Risk Margins for Reinsurance Business (with Direct Business Comparison)

This chart shows quartiles as well as the weighted mean of the outstanding claim liabilities stand-alone risk margin by reinsurance business class. Direct business classes are included for comparison. The weighted mean for both ‘category A’ reinsurance risk margins is not shown because each is distorted by results from large captive reinsurers that are atypical of reinsurers generally.

Horizontal bar chart comparing reinsurance risk margins by category and type. Quartile ranges shown as bars and weighted averages marked with orange diamonds.

4. PL Risk Margins for Reinsurance Business (with Direct Business Comparison)

This chart shows the quartiles as well as the weighted mean of the premium liabilities stand-alone risk margin by reinsurance business class. Direct business classes are included for comparison. The weighted mean for both ‘category A’ reinsurance risk margins is not shown because each is distorted by results from large captive reinsurers that are atypical of reinsurers generally.

Horizontal bar chart of premium liability risk margins for reinsurance categories. Displays quartile ranges and weighted means across direct, proportional and non‑proportional types.

5. Diversification Benefit % by Portfolio Concentration

This chart shows the quartiles as well as the weighted mean of diversification benefit adopted by insurers. Each set of rows represents a different segmentation of the insurers that reported a diversification benefit.

Horizontal bar chart showing diversification benefits across insurer groupings. Displays quartile ranges and weighted means by segmentation such as size, concentration and class count.

6. PL Scale up Factors by Class of Business

This chart shows the quartile range and median of the ratio of PL to OCL risk margins by class of business.

Vertical chart showing ratio of premium to outstanding claim risk margins by class. Quartile ranges shown as bars with median values marked for each insurance category.
