Gulf war / Hormuz · Strature analysis, not from the brief
Gulf war / Hormuz: what is at stake for New Zealand
New Zealand's direct stake is urea: Saudi Arabia supplied 55.6% of 2025 imports by value. All its fuel is imported refined, mainly from South Korea and Singapore.

Risks
- Pasture urea depends on one Gulf supplier: Saudi Arabia shipped 0.27 Mt in 2025.
- No refinery since Marsden Point stopped refining: South Korea and Singapore supplied 43.6% and 34.4% of 2025 product imports by value.
- Our calculation puts Gulf crude inside 65.9% of 2025 product imports.
Opportunities
- Gulf food importers may look for suppliers outside the region; New Zealand sold US$1.92bn of goods to GCC states in 2025, 4.1% of its exports.
- Urea from outside the Gulf is available: China supplied 25.9% and Malaysia 15.8% of 2025 imports by value.
Uncertainties
- Fuel stock days were not found; only the 6 days released in Mar 2026 are known. Estimate from press or commentary
- The embedded share assumes suppliers' 2025 crude slates; South Korea and Singapore may have cut Gulf crude after the war began.
What to watch
- 20 Nov 2026F-0074 resolves; spring top-dressing demand for urea is under way.
- MonthlyMBIE fuel stock updates (days of cover).
- MonthlyUrea import prices, against a world urea price of 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.
- S-001 F-0074 Renewed US or Israeli strike on Iran by 20 Nov 2026, 61%, our estimate, scored when it resolves.

Our calculations
- Gulf crude embedded in refined product imports (import share x supplier's Gulf crude share): 65.9% 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 43.6% × 69.9%; Singapore 34.37% × 71.76%; Malaysia 11.22% × 53.63%; Japan 3.23% × 94%; India 2.65% × 45%; China 1.31% × 39.7% = 65.91)
- Scenario: extra cost of replacing one quarter of Saudi urea at the April 2026 peak premium: US$25.5m (= 0.27 Mt / 4 × (850 - 472) US$/t = 67,500 t × 378 = US$25.5m)
- Scenario: extra refined product import bill for one quarter if prices rise 15%: US$0.21bn per quarter (= 5.55 / 4 × 15% (10-20%) = 1.39 × 0.15 = 0.21 (0.14-0.28))
- Scenario: one-quarter cost (fuel + urea) as % of GDP: 0.09% of GDP (= (0.208 + 0.0255) / 264.06 = 0.2335 / 264.06 = 0.088%)
