Insurance Faceoff: IAG vs. Suncorp - Which ASX Giant Has the Edge in FY25?

Team Veye | 11-Jul-2025

In a sector shaped by climate volatility and tight capital markets, two names have stayed on top of investor watchlists: Suncorp Group (ASX: SUN) and Insurance Australia Group (ASX: IAG). Both are heavyweight insurers with strong franchises across Australia and New Zealand, but they’re charting different courses in FY25, and investors are watching closely.

Performance Snapshot: Margins, Premiums, and Profit Levers

Let’s start with the numbers. For the first half of FY25, Suncorp posted a strong $1.1 billion NPAT, powered by the gain from its bank sale, softer natural hazard events, and higher global investment returns. Core earnings remained robust too $860 million in cash earnings, with general insurance delivering $658 million in profit after tax.

On the other side, IAG recently bumped its FY25 insurance profit guidance to a range of $1.6–$1.8 billion, up from $1.4–$1.6 billion. This was driven by natural perils costs coming in $200 million below budget. In simpler terms, fewer storms and disasters meant more cash hitting the bottom line.

What’s notable here is IAG’s reported insurance margin, now expected to land near the top of the 15.5% to 17.5% range, indicating impressive cost discipline and pricing control. Suncorp’s underlying insurance trading ratio (UITR) also held firm at 11.8%, suggesting margin resilience despite rising operating investments.

Strategic Focus: Simplification vs. Expansion

Suncorp has leaned heavily into simplification. Over five years, it offloaded its wealth, banking, and life arms, evolving into a pure-play insurer with a sharper operational focus. Its strategy now revolves around digitisation, improved underwriting, and investing in hazard readiness - like mobile disaster hubs and AI-powered claims systems.

IAG, by contrast, is in expansion mode. It’s executing twin acquisitions of RACQ Insurance in Queensland and RAC Insurance in Western Australia, adding over $3 billion in Gross Written Premium (GWP). These deals not only deepen IAG’s regional dominance but also promise $300 million in additional insurance profit and double-digit EPS accretion over time.

Where Suncorp is streamlining, IAG is doubling down, and both approaches are valid depending on your investment thesis.

Pricing Power and Segment Mix

When it comes to pricing power, Suncorp is holding its own. Consumer home insurance premiums rose 10.2%, motor insurance saw an 11.1% jump, and commercial lines added 9% GWP growth. Its pricing appears disciplined, and while home volumes slightly moderated, margins improved a trade-off the management seems happy to make.

IAG, meanwhile, is seeing 4-4.5% GWP growth for FY25, tempered by headwinds like the Coles exit and a softer NZ economy. However, in direct home and motor - the bread and butter for retail investors - growth is closer to 8%, with strong customer momentum. The RAC and RACQ tie-ups are expected to boost IAG’s GWP run rate by $3 billion, setting the stage for stronger long-term revenue flow.

Dividends and Capital Management

Suncorp declared a 41 cents per share interim dividend, fully franked, with a 61% payout ratio. It also committed to a $3.22 per share capital return from the bank sale. That’s real cash in investor pockets, and the yield appeal is hard to ignore.

IAG hasn’t declared a new dividend yet, but its capital position is solid, and the EPS accretive nature of its deals suggests potential for future dividend hikes.

Final Take: Margin Muscle or Market Grab?

Suncorp looks leaner, more focused, and capital generative. If you want steady margins, robust dividends, and strong operational execution, SUN is a compelling hold.

IAG, however, is placing a bold bet on market share. Its moves could supercharge revenue and earnings, but execution risk and integration complexity remain.

For now, Suncorp may win on stability and capital return, while IAG tempts those eyeing growth and expansion.
