War, shipping and drought could turn a grain-price rise into a full market shock.
What is known.
FAO said its Food Price Index averaged 136.0 in September 2026, up 1.5% month on month amid transport and weather pressures.
The question in this article is narrower than the general hazard: YES only if FAO’s first Food Price Index data release for December 2026, published by 15 February 2027, shows its Cereal Price Index at least 10.0% above FAO’s September 2026 Cereal Price Index in the same release vintage. Do not use the all-food index. The source documents what was known at publication, not proof that the forecast has come true.
What earlier cases show.
The current reference point comes from FAO's published record. Forecasts of disasters can fail because a risk signal is not a local outcome, and because official reporting and verification can lag real-world events.
Why it is a possibility.
FAO said September cereal prices faced transport disruption and weather concerns.
Harvests and alternative shipping routes could offset those pressures.
How the 41% was assessed.
Reference point. The published 41% is an editorial judgment from the FAO evidence available on 15 October 2026, not a measured frequency for this exact event.
Why it could be higher. FAO said September cereal prices faced transport disruption and weather concerns.
Why it could be lower. Harvests and alternative shipping routes could offset those pressures.
The editorial judgment. A 41% point estimate allows the defined event a real possibility by 2027-02-15 while respecting the countercase. The probability is frozen at publication for scoring.
Limits of the estimate. Official data can be delayed or revised, and a broad regional warning does not settle a specific event. The original rule and deadline control the result; a later evidence update may change the displayed current estimate without rewriting this article.
What could prevent it.
Harvests and alternative shipping routes could offset those pressures.
How it will be assessed.
YES only if FAO’s first Food Price Index data release for December 2026, published by 15 February 2027, shows its Cereal Price Index at least 10.0% above FAO’s September 2026 Cereal Price Index in the same release vintage. Do not use the all-food index.
