A 2027 U.S.–China conflict with Australia aligned to the U.S. China trade stops immediately, Taiwan exports are slowed/limited, and China launches large-scale cyber disruption in waves. This is a planning scenario, not a forecast. Planning scenario, not a forecast. No end date is set.

What happens

Goods to China stop, the marine premium is small, and the claims engine is already cyclical

  1. China trade stopping hits the goods that move on ships. China was 35.2 percent of goods exports. Iron ore and concentrates were 118755 million Australian dollars and 22.3 percent of all goods exports. That 22.3 percent is a global commodity share on the factsheet. It is not a China-only iron-ore share, and the factsheet does not print one.

  2. The insurer premium tied to that cargo is the marine and aviation class. Marine and aviation gross written premium was 326 million Australian dollars. Marine and aviation risks written were 327000. June 2026 gross claims were 169 million Australian dollars and December 2025 gross claims were 191 million Australian dollars. Marine energy and aviation was 2.2 percent of the Australia Pacific gross written premium mix, and that row includes energy and aviation, so it is not a cargo-only China share. The China share of the APRA marine premium is unpublished. Dividing one quarter of marine premium by a year of exports is not done here.

  3. Householders and reinsurance are the domestic shock already measured. Profit after tax was 134 million Australian dollars in the December 2025 quarter. Householders gross claims were 5448 million Australian dollars. Direct incurred claims were a calculated 50.4 percent of insurance revenue in the June 2026 quarter. The two inputs are the absolute value of direct-business incurred claims, 10262 million Australian dollars, and insurance revenue of 20376 million Australian dollars. The database prints the claims expense as a negative. This ratio is not an AASB 17 combined ratio. The file does not contain a combined ratio.

  4. Domestic motor and compulsory third party do not depend on a Chinese buyer. Domestic motor gross written premium was 4941 million Australian dollars. Compulsory third party risks written were 5909000. A China stop does not cancel those policies. Calling this market a U.S. personal-auto book would misstate the classes.

    apra.gov.au

  5. Taiwan exports slowing is a goods fact. Taiwan was 2.9 percent of goods exports, 15607 million Australian dollars, and the growth column prints a 6.0 percent decline. Singapore's goods-export share on the same table is also 2.9 percent, so the Taiwan sentence has to name Taiwan. No insurer Taiwan book was in APRA.

  6. A direct cyber hit lands on a concentrated carrier set. Financial and insurance services accounted for 32 percent of critical-infrastructure incidents. ASD's ACSC responded to over 1200 cyber security incidents in the factsheet year, and critical infrastructure made up 13 percent of incidents. Isolate vital OT and enabling systems for 3 months is preparedness guidance, not an observed insurer outage length.

How hard, how soon

0–3 months

  • Short-horizon quarterly analog: profit after tax was 134 million Australian dollars in the December 2025 quarter. Householders gross claims were 5448 million Australian dollars. Householders gross claims were a calculated 126.3 percent of householders insurance revenue. These are one-quarter prints, not a year-over-year peak.

    apra.gov.au

  • Short-horizon cyber guidance, not an observed outage: isolate vital OT and enabling systems for 3 months. The factsheet does not name an insurer. A foreign press report says a U.S. insurer paid 40 million dollars, about two weeks after the lockout. CNA is not commenting on the ransom. That case is foreign. The largest declared event incurred costs of 2.2 billion dollars is an Australian event-length claims analog, shorter than the December quarter, and it does not replace that quarter.

    cyber.gov.aunews.bloomberglaw.cominsurancecouncil.com.au

1–6 months

  • Observed path from the spike quarter to the June 2026 quarter: householders gross claims fell to 2130 million Australian dollars. Householders gross claims fell to a calculated 49.1 percent of householders insurance revenue. Industry profit after tax was 2253 million Australian dollars in that June quarter. QBE reported a combined operating ratio of 92.8 percent for the half year. That ratio is six months and is not the 0-3 month band.

    apra.gov.auinvestorpa.com

12+ months

  • Long-horizon run-rate: direct incurred claims were a calculated 50.4 percent of insurance revenue. Large-group insurance revenue was 12559 million Australian dollars. China was 35.2 percent of goods exports remains the cargo context. No multi-year combined ratio is published in this AASB 17 file.

Wave 1

Wave 1 direct is large-group direct insurers and claims operations. Financial and insurance services accounted for 32 percent of critical-infrastructure incidents, and the guidance is to isolate vital systems for 3 months. Wave 1 indirect is householders, because the class stops paying when the platform stops, and marine and aviation underwriters, because the cargo stops. This ordering is a planning model.

cyber.gov.auapra.gov.au

Wave 2

Wave 2 direct is reinsurers and brokers. Wave 2 indirect is the cyber class, which pays client incidents. Cyber gross written premium was 69 million Australian dollars. This ordering is a planning inference.

apra.gov.aucyber.gov.au

Wave 3

Wave 3 indirect is domestic motor and compulsory third party, and lenders mortgage insurers. They are local books. Domestic motor gross written premium was 4941 million Australian dollars. They are later than the claims utility and the China cargo. This ordering is a planning inference.

What to do

Day 7

  • Separate China-voyage marine wording from domestic motor, compulsory third party, and householders. Marine and aviation gross written premium was 326 million Australian dollars. China was 35.2 percent of goods exports.

    apra.gov.audfat.gov.au

  • Put large-group claims payment on the week-1 watch. Financial and insurance services accounted for 32 percent of critical-infrastructure incidents. Isolate vital OT and enabling systems for 3 months is the guidance test.

    cyber.gov.au

Day 30

  • Compare the latest quarter's profit after tax with the December 2025 print. Profit after tax was 134 million Australian dollars.

    apra.gov.au

  • Read householders gross claims against 5448 million Australian dollars and the reinsurance-expense row against the September 2025 print of 2976 million Australian dollars. Do not treat the December reinsurance expense of 326 million Australian dollars as the marine premium.

    apra.gov.au

Day 90

  • Ask whether marine gross written premium is still near 326 million Australian dollars after China shipments stop. Half of 326 is 163, and that half is the planning line below.

    apra.gov.au

  • Keep Taiwan at the goods share. Taiwan was 2.9 percent of goods exports. Do not invent an APRA Taiwan premium.

    dfat.gov.au

What to watch

By role

Large-group direct insurers

  • Test claims payment against a December-sized householders quarter of 5448 million Australian dollars of gross claims.

  • Keep the 3 month isolation capability on the week-1 list.

  • Watch profit after tax against the 134 million Australian dollar planning line.

apra.gov.aucyber.gov.au

Marine and aviation underwriters

  • Endorse China-destination cargo only. Do not apply 35.2 percent to the whole 326 million Australian dollar class. That product share was not published.

  • Use the 163 million Australian dollar planning line as the premium-break review.

  • Keep Taiwan cargo at the 2.9 percent goods share until a premium is filed.

dfat.gov.auapra.gov.au

Reinsurers

  • Read the December reinsurance-expense print of 326 million Australian dollars as timing, beside 2976 million Australian dollars in September 2025.

  • Size the householders event off gross claims of 5448 million Australian dollars and net claims of 3600 million Australian dollars.

apra.gov.au

Brokers and cyber-class underwriters

  • Keep cyber limits next to a book of 69 million Australian dollars of gross written premium and 8000 risks.

  • Do not treat domestic motor of 4941 million Australian dollars as the war book.
