ANZ Research says a developing La Niña could disrupt supply and demand across several commodities, with heavy rain in Asia and Australasia and drought risk in the Americas. The bank expects the biggest effect on winter heating and electricity demand.
Expected dry weather in South America and the US could weigh on soybean and corn yield prospects, supporting grain prices, while colder winter conditions could lift energy prices.
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 221 past bullish weather events, Natural Gas moved a median +3.3% over 5 sessions (61% higher; middle half -5.2% to +14.0%), and -0.3% over 20.
After 13 past neutral weather events, Crude Oil (WTI) moved a median +2.3% over 5 sessions (62% higher; middle half -0.9% to +4.7%), and +6.1% over 20.
