Gulf war / Hormuz · Strature analysis, not from the brief
Gulf war / Hormuz: what is at stake for Australia
Australia's direct stake is urea: Hormuz producers supplied 59.8% of 2025 imports by value. Its fuel comes from Asian refineries that run largely on Gulf crude.

Risks
- Urea for planting: Hormuz producers supplied 59.8% of 2025 urea imports by value, and 2.22 Mt of the 3.68 Mt by weight.
- Fuel stocks were reported at about 29-36 days of use during the 2026 crisis (an estimate; the source gives no date); the IEA's 90-day rule is counted differently, in days of net imports. Estimate from press or commentary
- Singapore supplied 25.9% of Australia's refined product imports in 2025, the largest share, and drew 71.8% of its own crude imports from Hormuz producers.
- The fuel excise was cut 50% in Mar 2026 (an estimate); a further cut would cost more revenue. Estimate from press or commentary
Opportunities
- LNG exports were US$38.45bn in 2025, and Australia was Singapore's second LNG supplier (35.1%) after Qatar (43.5%), so Asian buyers replacing Qatari LNG may turn to it.
- Urea from outside the Gulf is close by: Brunei, Malaysia and Indonesia supplied 0.39, 0.37 and 0.29 Mt in 2025.
Uncertainties
- Fuel stock days come from a Wikipedia summary, not the official petroleum statistics, which could not be reached. Estimate from press or commentary
- The embedded Gulf crude share assumes suppliers' 2025 crude slates; several cut Gulf crude after the war began.
- Farm exports to the Gulf may lose buyers: GCC states took 8.8% of barley exports and 69.2% of live sheep and goat exports in 2025, but the sheep trade is small (US$24.3m), and no trade figures since the war began were found.
What to watch
- 20 Nov 2026F-0074 resolves; a renewed strike before the next autumn planting would test urea supply.
- MonthlyAustralian Petroleum Statistics: days of cover for diesel, petrol and jet.
- MonthlyUrea imports by origin and the world urea price, against US$472 a tonne before the war (World Bank, Feb 2026).

Briefs and questions
- T-003 · Which economies are most exposed to the Gulf fertiliser shock? Gulf economies supply about a quarter of world nitrogen fertiliser exports.
- T-003 · Had Hormuz crude flows recovered by late September 2026? Refined products recovered least after the reopening.

Estimates from press or commentary

Our calculations
- Urea imports from Hormuz Gulf producers, volume: 2.22 Mt (= 0.8626 + 0.5952 + 0.5317 + 0.2283 Mt (UN Comtrade 2025 partner rows) = 2.218)
- Gulf crude embedded in refined product imports (import share x supplier's Gulf crude share): 54.6% of product imports (= sum over suppliers of (share of product imports by value, UN Comtrade HS 2710 2025 × supplier's Gulf share of crude imports): Korea 25.08% × 69.9%; Singapore 25.86% × 71.76%; Malaysia 13.35% × 53.63%; India 8.25% × 45%; Taiwan 8.25% × 61%; China 6.56% × 39.7% = 54.60)
- Scenario: extra cost of replacing one quarter of Hormuz-Gulf urea at the April 2026 peak premium: US$0.21bn (= 2.22 Mt / 4 × (850 - 472) US$/t = 0.555 Mt × 378 = US$0.210bn)
- Scenario: extra refined product import bill for one quarter if prices rise 15%: US$1.11bn per quarter (= 29.69 / 4 × 15% (10-20%) = 7.42 × 0.15 = 1.11 (0.74-1.48))
- Scenario: one-quarter cost (fuel + urea) as % of GDP: 0.07% of GDP (= (1.11 + 0.21) / 1798.52 = 1.32 / 1798.52 = 0.073%)
