Australia’s private health insurance (PHI) sector continues to face structural pressures, including rising healthcare costs, an ageing membership base and regulated premium increases. While these challenges have fuelled concerns about long‑term sustainability, sector profitability has remained relatively stable, reflecting higher underlying costs rather than excess margins.
A key shift highlighted in this paper is the growing importance of investment income. As interest rates have normalised, investment returns now account for a significant share of insurer profits, particularly for smaller funds. This changing balance strengthens the role of investment strategy in supporting overall financial outcomes.
The paper explores how asset allocation, ownership structure and risk tolerance differ across the sector, and why many insurers may be better positioned than commonly assumed to diversify portfolios beyond cash and short‑duration assets. We believe the current environment presents an opportunity for private health insurers to re‑test investment strategy to improve resilience and support long‑term business objectives.
