From 2005 to 2010, the prices of expiring U.S. grain futures contracts routinely exceeded the corresponding delivery market cash prices. This phenomenon, termed “non-convergence,” was particularly noteworthy in wheat markets. By appearing to simultaneously imply different prices for the same grain, non-convergence can create market uncertainty. What explains this phenomenon? When grain futures contracts expire, the seller gives the buyer a certificate that can be exchanged for a specific amount of grain, rather than transferring the actual physical commodity. Because the buyer can hold these certificates indefinitely, they provide a method to store grain, and futures exchanges charge the buyer a recurring certificate storage fee. During 2005-2010, market conditions often led the price of storing the physical commodity to exceed certificate storage fees, so expiring futures contracts became a more attractive way to store grain than holding physical grain in a warehouse. As a result, the same grain became more valuable when represented by an expiring futures contract, so the price of futures contracts rose above cash market grain prices. Addressing the divergence in storage rates is the most effective way to prevent future episodes of non-convergence. This chart is from ”Solving the Commodity Markets’ Non-Convergence Puzzle,” in ERS’s August 2013 Amber Waves magazine.

USDA’s Conservation Reserve Program (CRP) engages farmers in long-term (10- to 15-year) contracts to establish conservation covers on environmentally sensitive land. As of June 2013, about 27 million acres of farmland were enrolled in the program. An important provision within CRP is that under certain circumstances, farmers can utilize their CRP lands for managed or emergency haying and grazing. The haying and grazing of CRP land can provide important benefits to farmers, particularly during major droughts when other sources of livestock feed are scarce, and, if done correctly, can also improve the environmental value of the conservation covers. During the 2012 drought, farmers conducted emergency haying and grazing on almost 2.8 million acres and managed haying and grazing on another 700,000 acres. This chart is found in the Amber Waves article, “The Role of Conservation Program Design in Drought-Risk Adaptation,” July 2013.

Farmers can adapt to their local climate in many ways, including through participation in USDA programs. In regions of the country that face higher levels of drought risk, farmers are more likely to offer eligible land for enrollment in the Conservation Reserve Program (CRP). As a consequence, CRP is both more competitive in these regions and drought-prone counties are more likely to face a binding CRP acreage enrollment cap. When counties are near their enrollment cap, farms are less likely to offer eligible land for CRP because those offers are less likely to be accepted for enrollment. In simulations of offer rates based on observed historical data, a national increase in the county CRP acreage enrollment cap to 35 percent of cropland in each county (from the current level of 25 percent), results in more offers from eligible farmers in drought prone regions of the Great Plains and the Intermountain West. This map is found in the ERS report, The Role of Conservation Programs in Drought Risk Adaptation, ERR-148, April 2013.

Recent ERS research explored how climate change could affect the cost of the Federal Crop Insurance Program (FCIP). Researchers trained statistical models to predict crop yields from historical weather data, and used weather simulations from climate models to build scenarios showing how yields might respond to climate change. Economic models then simulated how farmers and markets might respond to changes in weather and yields. The study explored potential impacts in the year 2080, and compared climate scenarios arising from different projections of greenhouse gas emissions levels to a hypothetical future with climate similar to that of the past several decades. Under the scenario with moderate emissions reductions, in which farmers adapt to changes in climate with adjustments to what they plant, where they plant it, and how they manage it, the cost of today’s FCIP would be on average about 3.5 percent higher than under a future with a climate similar to that of the recent past. Under the scenario in which emissions trends continue, the cost of FCIP would increase by an average of 22 percent. The estimated increases in the cost of FCIP are an average across the climate models shown in the chart—some models are more optimistic, while others more pessimistic. Cost estimates are higher in scenarios with no adaptation. This chart appears in the ERS report, Climate Change and Agricultural Risk Management Into the 21st Century, released July 2019.
