# Cocoa, coffee and grain prices: volatility due to the weather

> The article describes divergent agricultural price and production signals in 2026: FAO grain prices were up year over year in September, while coffee prices fell amid a large Brazilian crop. It also cites weather-related pressure on corn and a lower global grain harvest forecast, alongside a recovery in cocoa production and a decline in Colombia’s coffee harvest.

## Why it matters

Heat and drought can constrain corn and other grain supplies, supporting prices, while a large Brazilian coffee crop illustrates how favorable production can pull prices lower. The mixed outlook points to greater procurement uncertainty rather than a uniform direction across commodities.
