Lessons

“USDA’s September 2008 assessment identified export restrictions as a major contributor to the rice price surge despite record production and rising global stocks. Our US rough-rice futures comparisons describe a different benchmark; they do not quantify the restrictions’ effect.”

“Chicago SRW wheat (ZW=F) was up 20.1% from Jul to Dec 2010 month-end, but down 11.6% from Jul 2010 to Jun 2011. Different endpoints give different descriptions; neither comparison measures the ban’s price effect or proves that competitors fully offset it.”

“World Bank palm-oil monthly prices rose 2.0% from Apr to May 2022 and fell 40.5% from Mar to Jul. These windows overlap a short export ban and a wider vegetable-oil correction; they do not measure the ban’s independent price effect.”

“FAO’s All Rice Price Index rose 9.8% from Jul to Aug 2023. US rough-rice futures ended Jul 2023 to Sep 2024 down 1.2%, but that different benchmark and longer window cannot describe Asian rice markets’ reaction or measure the ban’s effect.”

“During Nov 2023 to Apr 2024, Chicago wheat futures rose slightly while corn and soybeans fell, alongside Red Sea shipping disruption. These benchmarks do not measure freight or delivered import costs, and their net changes cannot establish that the disruption had no commodity-price effect.”

“The Ever Given blockage delayed shipping for six days. This record contains contemporary oil reporting but no verified agricultural event-window price comparison; it cannot establish the absence of an agricultural price effect.”

“ICE arabica Coffee C (KC=F) rose 95.7% from Jan 2024 to Mar 2025 month-end, then fell 19.2% by June. This is not a robusta benchmark, and these windows do not separate Brazil’s weather from inventories, demand, positioning, or conditions in other origins.”

“CBOT corn (ZC=F) rose 22.3% from Feb to Aug 2012 month-end, then fell 38.3% by Aug 2013. Those comparisons span different harvests and contracts; they do not isolate drought damage or establish that the next harvest will reverse a weather shock.”

“ICE US cocoa (CC=F) rose 352.3% from Jan 2023 to Dec 2024 month-end, then fell 32.3% by Mar 2025. Reported deficits provide context, but these price comparisons do not quantify the contributions of weather, disease, inventories, demand, or positioning.”

“Drought-driven liquidation is a two-sided shock: more cattle shipped now can mean fewer cattle later. As of 2026-10-07 the direction is genuinely mixed, so this record's job is to watch whether shipments reverse and the supply score moves by the 2026-11-06 check-back — not to call the price.”

“Prices moved in different directions during the selected El Niño windows. These observations do not measure El Niño’s effect: KC=F tracks arabica rather than Vietnam’s robusta, and ZR=F tracks US rough rice rather than Asian rice export prices.”

“Chicago SRW wheat futures rose early in 2022 and later gave back part of that rise. The Black Sea disruption and subsequent changes in trade and supply are documented, but these price windows do not isolate the war’s effect or show where prices would have been without it.”

“Chicago SRW wheat (ZW=F) rose 4.6% from Jun to Jul 2023 month-end, then stood 14.9% below June by September. The later decline does not show that leaving the grain deal had no bullish effect; prices might have fallen further without it.”

“Published urea benchmarks rose during the June 2025 conflict, while several US agricultural futures ended broader monthly windows lower. Those different markets and windows cannot establish that the conflict had no agricultural price effect.”

“A cluster of supply-tightening lumber headlines in early October 2026 coincided with LBR=F falling about 10% over the prior 20 days. The narrative and the price were telling different stories; this record exists to check which one was right by the 2026-11-06 check-back.”

“A 16% three-week rally in OJ=F arrived in September–October 2026 with no identifiable supply shock in the screened evidence. The honest lesson is about the limits of shock narratives: prices move on more than documented disruptions, and a WATCH score without a mechanism is a question, not an answer.”
