A small cut.
A large price.
A pattern-recognition library of state commodity coercion. The recurring signature: a single-digit-percent supply removal produces a multiple of that in price — and the weapon has moved from oil to gas, grain and critical minerals.
Commodity weaponization is a recurring, quantifiable pattern with a stable transmission signature: a supply removal of single-digit percent of global volume produces a multiple of that in price response, with duration set by substitution lead time and policy response. This is a pattern-recognition library of historical and active episodes in which a state restricted a critical commodity for geopolitical leverage. The weapon has diversified from oil (1970s–90s) to gas (2022), grain (2022–23) and critical minerals (2023–25) — so the tracker monitors non-energy commodities with equal rigor.

| Fertilizer export restrictions | 2021–2026 | Urea, phosphate | Russia quotas through Dec 2026; China phosphate paused to Aug 2026 | Urea +80% to >$850/t by Apr 2026 (Section 5) | Ongoing | Morocco (OCP), Saudi (Ma'aden), Brazil |
Volume-to-price asymmetry — a ~4–7% global supply removal (1973, 1979, 1990) historically generated 100–300% price moves, because demand for energy and food is short-run inelastic.
The weapon has diversified from oil (1970s–90s) to gas (2022), grain (2022–23) and critical minerals (2023–25) — so the tracker must monitor non-energy commodities with equal rigor.
Concentration is the precondition — every episode involved a supplier holding >25% of a traded commodity (China REE ~70%+, Indonesia palm ~50%, India rice ~40%, Gulf urea ~36%).
01 1973 Arab Oil Embargo (Reference Pattern)StructuralProduction cut ~5%/mo + US shipment ban quadrupled oil $2.90→$11.65/bbl by Jan 1974; catalyzed IEA and SPR creation. Anchor episode for volume-to-price asymmetry. high
02 Russia Gas Weaponization 2021–2022StructuralEU pipeline gas imports −80% vs 2019–21; TTF >€200/MWh in 2022 (peak ~€300+), eased to ~€30 by Aug 2023; EU demand −20%. Modern weaponization template. high
03 China Rare-Earth Export Controls 2023–2025DynamicEscalating controls (gallium/germanium Jul 2023 → 7 heavy REE Apr 2025); REE-magnet exports −74% YoY May 2025; heavy-REE ex-China +250% premium H2 2025. medium
HIGH — Federal Reserve 1973 embargo prices; Atradius/IEA Russia-gas figures; documented export bans (India rice, Indonesia palm) and FAO grain-index moves.
MODERATE — China REE-magnet −74% and +250% premium (Defense One/Kamoa, T2); OPEC+ pledged-volume aggregation.
Quarantined — Cross-episode price-multiple generalizations are pattern heuristics, not forecasts.
