Australia Named the Standout Climate Risk for Insurers as Moody's Warns Weather Losses Will Keep Rising

SYDNEY — Australia stands out as the market most exposed to climate-driven weather losses in Asia-Pacific, according to a new Moody's Ratings regional report published on 2 November 2026, which warns that weather-related losses will keep rising across the region but will remain greatest in Australia and Japan.

The ratings agency's assessment, reported by Insurance News Australia, puts Australia in a distinctive position: because property insurance take-up is high, Australian insurers absorb a far larger share of the economic damage from cyclones, floods, hail and bushfires than their counterparts in most other Asia-Pacific economies, where insurance markets outside Japan are less mature. That exposure, Moody's says, is now being sharpened by changing catastrophe patterns, population shifts into hazard-prone areas, and claims that are becoming more severe.

What Happened

Moody's Ratings examined weather exposure across Asia-Pacific property and casualty insurers and concluded that losses are set to rise region-wide, with the impact varying sharply by market. "Weather-related losses will rise across [Asia-Pacific], but the impact will vary … it will remain the greatest in Australia and Japan," the agency said, according to Insurance News.

"Australia stands out because its insurers already bear a large share of economic losses from weather events," Moody's said. The industry covers about 50 to 75 per cent of weather perils, including cyclone, flood, hail and wildfire — a level similar to Japan's coverage for typhoon, flood and hail, according to the report.

The agency pointed to three forces behind the large insured losses in Australia: evolving catastrophe patterns, demographic shifts, and increasing claims severity. Floods and hailstorms are becoming more frequent and more severe, Moody's said, while increasingly affecting regions that were historically less exposed. Wildfire losses are also increasing as hotter, drier and windier conditions raise fire risks, and as population growth continues to drive residential development into bushfire-prone areas, expanding insurers' exposure to potential losses.

Rebuilding has also become more expensive. High labour costs and construction bill inflation have increased insurers' rebuilding expenses, Moody's said, and "more stringent building and resilience standards for reconstruction have further driven up insurers' claims costs."

Background

Australia's position reflects a combination of geography, settlement patterns and insurance depth. Unlike much of Asia-Pacific, where low insurance penetration has so far limited insurers' exposure to weather losses, Australian households and businesses widely hold property cover — so when a disaster strikes, a large share of the bill lands with insurers rather than being absorbed uninsured by households or governments.

That picture is changing elsewhere in the region, too. Insurance Asia, reporting on the same Moody's analysis, noted that insurers in major Asia-Pacific markets have so far had limited exposure to weather-related losses because of low penetration, except in Australia and Japan — but urbanisation, economic growth and wider insurance coverage are expected to increase their exposure over time. Insurers in Australia, China, Japan, South Korea and Taiwan face different levels of risk, Moody's said.

The report lands in a year that has, so far, been comparatively quiet for global catastrophe losses. Gallagher Re's third-quarter 2026 Natural Catastrophe and Climate Report, published on 21 October, put global economic losses from natural catastrophes at at least $242 billion in the first nine months of 2026, with insured losses of about $92 billion — the lowest totals for the first three quarters of a year since 2015 and 2019 respectively. The reinsurer attributed the relatively low losses to the absence of major disasters, despite a near-average number of catastrophe events, and noted that the third quarter marked the sixth consecutive quarter without a single natural catastrophe generating more than $10 billion in insured losses.

Moody's message is that a quiet stretch should not be mistaken for a trend reversal. Its analysts expect insurers to keep relying on strong capital buffers to absorb losses, while using reinsurance, risk-based pricing and stricter underwriting to manage growing exposure. Insurers in major Asia-Pacific markets maintain risk-based solvency ratios well above regulatory minimum requirements, according to the agency, and it expects them to retain earnings and manage capital carefully as catastrophe exposure grows.

Why It Matters

The findings matter first for Australian households, because insurers' ability to reprice risk is doing much of the work of keeping the system solvent. Moody's said premium changes have "helped Australian … insurers maintain underwriting profit" — a sign that higher premiums are, for now, offsetting higher claims. But that balance is delicate: if premiums rise too fast, coverage becomes unaffordable and take-up falls; if they rise too slowly, insurers' capital erodes. Either outcome would leave more of the next disaster's cost with households and governments.

The findings also matter for the region's climate adaptation debate, days before the COP31 climate conference opens in Antalya, Türkiye, on 9 November. Australia's experience — high coverage, rising severity, and rebuilding costs inflated by tougher standards — is a preview of what other Asia-Pacific markets may face as insurance penetration rises. Moody's argues that policy support and regulatory development will be needed to keep catastrophe risks insurable, including government reinsurance capacity, premium subsidies and public-private risk-sharing mechanisms. "Policy support and regulatory development will enhance insurability of catastrophe risks," the agency said, adding that regulatory support for insurance-linked securities "will also attract private capital into the catastrophe risk market, expanding insurers' risk transfer capacity and diversifying their reinsurance capital."

A further complication is El Niño. In a separate Moody's assessment reported in October, the agency said El Niño tends to increase heat and dryness in Australia, raising bushfire risk by more than 50 per cent compared with non-El Niño years, while potentially reducing tropical cyclone risk. It also warned that a shift from unusually wet conditions to a hotter, drier period can increase the risk of a major bushfire by increasing available fuel, particularly when combined with hotter-than-normal conditions. With a strengthening El Niño now under way, according to the World Meteorological Organization, that interaction between perils — one risk rising while another falls — is exactly the kind of complexity Moody's says catastrophe models must capture rather than modelling each peril in isolation.

What Happens Next

Several near-term developments will test Moody's outlook. In Australia, the Australian Prudential Regulation Authority's revised reinsurance framework, finalised in July, is due to take effect on 1 January, giving general insurers easier access to catastrophe bonds and other stop-loss options. Moody's vice president of ratings Kelvin Kwok called the change credit-positive. "We view the changes as credit-positive for Australian insurers because they reduce the regulatory burden associated with accessing alternative reinsurance, including insurance-linked securities," Kwok said. "This should give insurers greater flexibility to diversify their reinsurance protection and transfer catastrophe risks to a broader pool of capital. Over time, such flexibility will become increasingly valuable as weather-related losses rise in frequency and severity."

Reinsurance will remain a central shock absorber. "Reinsurance is a key mitigant of earnings and capital volatility, particularly for insurers in Australia, Japan and Taiwan," Moody's said. How reinsurers price the coming renewal season — and whether capital markets deepen their appetite for catastrophe bonds — will shape premiums for Australian households in 2027.

The wider policy test comes at COP31 in Antalya from 9 to 20 November, where governments will debate climate finance and adaptation support for countries with fewer resources. Australia's story shows that even a wealthy, well-insured market faces mounting pressure from weather losses; for less-insured economies, the same hazards translate into uninsured devastation. Whether the summit produces concrete support for adaptation and risk-sharing, or another round of deferred promises, will determine how much of the next disaster's cost falls on the people least able to bear it.

FAQ

What did Moody's Ratings actually warn about?

Moody's warned that weather-related losses for Asia-Pacific insurers will rise, and that the impact will remain greatest in Australia and Japan, because Australian insurers already bear a large share of economic losses from weather events.

How much weather risk do Australian insurers cover?

According to Moody's, the industry covers about 50 to 75 per cent of weather perils, including cyclone, flood, hail and wildfire — similar to Japan's coverage for typhoon, flood and hail.

Why are insured losses rising in Australia?

Moody's cited evolving catastrophe patterns, demographic shifts and increasing claims severity: floods and hailstorms are becoming more frequent and severe and reaching previously less-exposed regions, wildfire losses are rising in hotter, drier, windier conditions, more homes are being built in bushfire-prone areas, and rebuilding costs have climbed with labour and construction inflation and tougher building standards.

Are Australian insurers still profitable despite the losses?

Moody's said premium changes have helped Australian insurers maintain underwriting profit, and that solid capital buffers remain an important source of resilience — but it expects insurers to keep relying on reinsurance, risk-based pricing and underwriting discipline as exposure grows.

What is changing for Australian insurers on 1 January?

The Australian Prudential Regulation Authority's revised reinsurance framework, finalised in July, takes effect on 1 January, supporting insurers' access to catastrophe bonds and stop-loss options — a change Moody's vice president Kelvin Kwok described as credit-positive.
