Rabobank's annual Outlook report, Good Buy, Low Prices, lists weather, trade and currency risks to global food prices in 2018. It notes that a La Niña could bring heat and dryness to Americas grain areas and flooding to Asian palm oil plantations.
Global grain and oilseed stocks are high but balance sheets are tightening.
Tightening balance sheets leave less cushion against weather shocks, which raises the chance of price spikes in corn, soybeans and wheat. A stronger dollar from US rate rises could make US exports less competitive.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 224 past neutral weather events, Wheat (SRW) moved a median -0.1% over 5 sessions (46% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
