The IRI March 2019 ENSO Quick Look reports that tropical Pacific sea surface temperatures sit in the weak El Niño range, with subsurface waters warming. The official CPC/IRI outlook carries an El Niño advisory, giving an 80% chance of El Niño through March-May, falling to 60% for June-August.
A developing El Niño typically brings above-normal US corn and soybean yields but can trim wheat and dry parts of Southeast Asia and Australia, so the outlook weighs on grain supply expectations.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
After 1,072 past bullish weather events, Wheat (SRW) moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
After 179 past bullish weather events, Rough Rice moved a median +0.4% over 5 sessions (55% higher; middle half -1.4% to +2.5%), and +2.2% over 20.
