Insurance Australia Group (IAG), the country's largest insurer, reported a substantial half-year net profit of $778 million, marking a 91 percent increase compared to the same period last year, reflecting the impact of rising premiums, improved weather conditions, and a $200 million release from its COVID-19 business interruption provision.

IAG's chief executive, Nick Hawkins, stated that the insurance market is likely to see a slowdown in premium increases, coinciding with decreasing inflation rates.

Hawkins noted that the previous two years had been marked by significant cost increases related to supply chains and labor, alongside changes in reinsurance driven by world events.

He highlighted that the pressures on motor vehicle insurance prices have decreased substantially, whereas property insurance prices are still relatively high.

Despite the anticipated easing of premium hikes, Hawkins indicated that premiums would remain notably above the current inflation rate of 2.4 percent, with IAG forecasting that premium growth would be in the mid-to-high single digits.

The rising insurance premiums have been a significant contributor to inflation in Australia, especially following the floods in eastern Australia in 2022. Data from the Australian Bureau of Statistics indicated that insurance premiums rose by 1.1 percent in the December quarter, marking the weakest quarterly increase since June 2022.

Hawkins also commented on potential external economic factors, noting that he had not observed any immediate impact from tariffs imposed during the Trump administration on inflation levels.

As the industry adjusts, IAG investors reacted to the announcement of slower gross premium growth, which increased by 6 percent for the first half of the 2025 financial year compared to a 12 percent rise the previous year, leading to a more than 12 percent drop in IAG shares.

In addition to its profit surge, IAG announced an interim dividend of 12 cents per share, up from 10 cents the previous year.

UBS analysts have suggested that heightened competition and slowing premium increases could limit future earnings growth potential.

In light of ongoing regulatory scrutiny, IAG has made substantial investments to enhance customer service and address compliance issues raised by the Australian Securities and Investments Commission (ASIC), which has taken legal action against the insurer for allegedly misleading customers regarding loyalty discounts.

Hawkins acknowledged the past complexities within the company's systems that contributed to these issues and confirmed efforts to streamline operations and improve service reliability.

The planned changes aim to mitigate prior mistakes and bolster customer trust in IAG's offerings.
