When interest rates rise, most companies start to sweat—debt becomes costlier, consumers pull back, and growth slows. But not every stock wilts under pressure. In fact, some thrive.

Enter Insurance Australia Group (ASX: IAG) — a powerhouse in the general insurance space that is proving to be one of the rare winners in a high-interest-rate environment.

At a time when investors are looking for shelter from rate-driven volatility, IAG is quietly delivering the kind of performance that makes it a compelling pick for both income and growth.

Company Snapshot: Who Is IAG?

IAG isn’t just another name in the insurance game—it’s a market leader. With a presence across Australia and New Zealand, IAG owns a suite of trusted brands including:

1. NRMA Insurance
2. CGU Insurance
3. SGIO and SGIC
4. AMI (New Zealand)

The company offers a wide range of general insurance products—car, home, business, and travel—and serves millions of policyholders.

Importantly, IAG also manages an investment portfolio exceeding $10 billion, making it highly sensitive to interest rate movements. As rates rise, the return on this massive asset base rises too—a hidden lever that powers profits.

Financial Performance: Strong First Half of FY25

IAG has already shown its strength in the current high-rate climate:

Revenue: $8.84 billion in H1 FY25, up 9.56% YoY

Net Income: $778 million, a whopping 91% YoY growth

P/E Ratio: 17.19, reflecting moderate valuation

Dividend: $0.12 per share, with a 3.43% trailing yield

The numbers tell a clear story—IAG is not just surviving, it’s thriving.

Growth Drivers: Why IAG Benefits From Higher Rates

1. Higher Investment Income

Insurance companies collect premiums upfront, often long before they pay out claims. This money is typically parked in safe investments like government bonds.

When rates are low, returns on these investments are minimal. But as interest rates climb, so do the yields.

In FY24, IAG’s investment income surged thanks to rising yields—a trend that looks set to continue if interest rates remain elevated. This means the company can generate more income simply by holding onto policyholder premiums.

2. Premium Rate Increases

Insurance premiums are rising, and IAG has been proactive in passing these increases on to customers. The company reported double-digit premium growth, particularly in car and home insurance, where inflation and climate-related claims have driven costs higher.

Rather than absorb the hit, IAG has maintained its margins by adjusting its pricing model. In fact, gross written premiums (GWP) increased by more than 10% YoY—a sign of both pricing power and customer loyalty.

3. Strong Capital Position

High interest rates make borrowing expensive. But IAG is sitting pretty.

Its balance sheet is well-capitalised, with regulatory capital comfortably above required levels. This reduces its reliance on debt and gives it more flexibility in managing operations and returning capital to shareholders.

With a conservative financial structure, IAG is insulated from the risks that are plaguing over-leveraged companies.

4. Efficiency Through Innovation

IAG is not resting on tradition. It’s investing heavily in digital transformation, including:

1. Claims automation
2. AI-based fraud detection
3. Data-driven risk assessment

These tools are expected to improve customer service, speed up processing, and reduce claim leakage. Over time, that translates to better margins and stronger profitability.

What Makes IAG Stand Out in 2025?

Let’s break it down:

1. Defensive Business Model: Insurance is a must-have, even during economic slowdowns. That makes IAG relatively recession-resistant.
2. Positive Rate Sensitivity: Unlike many businesses that struggle when rates rise, IAG actually benefits from it.
3. Reliable Dividends: A steady income stream with a yield of over 3% makes IAG attractive for income-focused investors.
4. Proven Profit Growth: With net income nearly doubling in H1 FY25, the company has demonstrated it can grow even in tough environments.
5. Smart Capital Allocation: Strong reserves and disciplined cost management set it apart from peers.

Risks to Watch

No investment is without risk. For IAG, key challenges include:

1. Extreme Weather Events: Floods, fires, and storms can increase claim volumes unexpectedly.
2. Regulatory Pressures: Changes in capital requirements or pricing guidelines could impact operations.
3. Customer Retention: Premium hikes may test loyalty, though IAG’s strong brand helps mitigate this.

However, the company’s proactive risk management strategies and diversified brand portfolio offer strong defenses.

Final Verdict: A Smart Pick in a High-Rate Economy

In a world where rising interest rates are squeezing corporate profits and dragging down growth stocks, Insurance Australia Group (ASX: IAG) emerges as a clear winner.

It is well-positioned to benefit from:

1. Increasing premium income
2. Strong operational execution
3. A capital-light, low-debt structure

All while paying a solid dividend and keeping costs in check.

For investors seeking a balance of stability, income, and upside potential, IAG could be a strong addition to the portfolio—particularly in this new era of elevated interest rates.
