A Congressional Research Service report from October 5, 2020 details U.S. farm revenue support outlays under the ARC and PLC programs for 2014-2020. It notes that corn, soybeans and wheat made up 83% of the 260 million base acres enrolled in the 2014 sign-up.
Base acreage fell to 253.5 million under the 2019 sign-up.
Changes in base acre enrollment and support payments shape the revenue cushion behind planting decisions for the largest feed grains, but the report has little immediate effect on prices.
After 1,623 past policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.4% to +1.5%), and +0.4% over 20.
After 1,905 past policy events, Soybeans moved a median +0.1% over 5 sessions (52% higher; middle half -1.4% to +1.8%), and +0.2% over 20.
After 1,019 past policy events, Wheat (SRW) moved a median -0.1% over 5 sessions (49% higher; middle half -1.7% to +1.5%), and +0.2% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
