Net Premiums Written: What It Means for Australian Insurance in 2025

Net premiums written isn’t just industry jargon — it’s a financial metric that’s shaping the future of Australia’s insurance market in 2025. Whether you’re a policyholder, investor, or just trying to make sense of your insurer’s annual report, understanding this number is crucial for making smarter decisions about coverage, pricing, and even which companies are likely to weather the next big economic storm.

What Are Net Premiums Written?

At its core, net premiums written (NPW) is the total value of insurance premiums an insurer retains after accounting for the premiums it cedes to reinsurers. In other words, it’s what the insurer keeps on its books as risk, after sharing some of the exposure with other companies. The formula is straightforward:

• Net Premiums Written = Direct Premiums Written + Assumed Premiums – Ceded Premiums

This metric is a real-time snapshot of the insurer’s risk appetite and business growth. For example, if QBE Insurance writes $10 billion in premiums but cedes $2 billion to reinsurers, its net premiums written stand at $8 billion. That’s the figure that tells you how much risk QBE is actually taking on — and how much revenue it stands to gain (or lose) from claims.

Why Net Premiums Written Matters in 2025

In the wake of 2024’s catastrophic weather events and new APRA regulations, net premiums written has become a key metric for both industry insiders and everyday Australians. Here’s why:

• Insurer Strength: Higher NPW signals that an insurer is confident in its underwriting and less reliant on expensive reinsurance. This can mean more stability for policyholders.
• Pricing Trends: APRA’s 2025 guidelines have tightened the screws on capital requirements, forcing insurers to balance risk retention with solvency. Many have responded by tweaking their reinsurance strategies, which directly impacts NPW — and, ultimately, the premiums you pay.
• Claims Capacity: A robust NPW means the insurer is well-positioned to pay out on claims, especially after a year marked by floods, bushfires, and rising property values.

For instance, in early 2025, Suncorp reported a 7% increase in net premiums written compared to the previous year, driven by both organic policy growth and a strategic reduction in reinsurance. This not only boosted their profitability but also gave investors confidence in Suncorp’s ability to handle large-scale disaster payouts.

How Net Premiums Written Affects You

It’s easy to think of NPW as a number that only matters to actuaries and CFOs, but it has real-world consequences for everyday Australians:

• Policy Pricing: Insurers with higher NPW often have more flexibility to offer competitive premiums — but may also be exposed to higher risks (and, in a bad year, premium hikes).
• Claim Reliability: A solid NPW ratio indicates that an insurer is not over-reliant on reinsurance and can pay claims from its own reserves, a critical reassurance during major events.
• Industry Competition: As insurtech startups and mutuals enter the market, tracking their NPW growth can help you spot which newcomers are gaining traction — and which are playing it safe.

With the 2025 insurance landscape in flux, especially after APRA’s updated reporting standards and an uptick in climate-driven claims, net premiums written is now front and centre in financial reviews, boardroom decisions, and, yes, even the fine print of your policy renewal letter.

2025 Trends: Regulatory Shifts and Market Moves

This year, APRA’s new Prudential Standard GPS 123 (effective January 2025) requires more granular reporting on reinsurance arrangements and risk retention. Insurers are recalibrating their portfolios, and the impact is already visible:

• Reinsurance costs are up due to global catastrophes, pushing some insurers to retain more premiums and risk in-house, lifting NPW.
• More transparency: Insurers now disclose NPW by business line (home, auto, commercial), helping consumers and investors compare apples with apples.
• Insurtech innovation: Digital-first insurers are leveraging AI to price risk more precisely, often resulting in leaner reinsurance programs and higher NPW ratios.

These shifts mean that net premiums written isn’t just a backward-looking metric — it’s a leading indicator of how insurers are adapting to a riskier, more regulated world.

Conclusion: Keep an Eye on Net Premiums Written

Whether you’re shopping for a new policy, reviewing your portfolio, or just want to understand how insurers make money, net premiums written is a number worth watching in 2025. As regulations tighten and risks mount, this metric reveals which companies are poised for growth, stability, and reliability — and which might leave you exposed when it matters most.
