CRS published a summary and side-by-side comparison of the 2018 Farm Bill (P.L. 115-334), signed December 20, 2018.
CBO scores mandatory programs at $867 billion over FY2019-FY2028, budget neutral versus extending the 2014 law.
The bill largely extends existing commodity support and crop insurance programs through FY2023, so it provides policy continuity with little new price impulse for feed grains or meals.
After 439 past neutral policy events, Corn moved a median +0.1% over 5 sessions (51% higher; middle half -1.3% to +1.2%), and +1.1% over 20.
After 554 past neutral policy events, Soybeans moved a median +0.0% over 5 sessions (51% higher; middle half -1.4% to +1.6%), and +0.6% 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.
