Corn returns for 2014 are projected under yield scenarios representing drought, median, and high yields for a farm expecting a yield of 195 bushels per acre with a $4.80 projected price. Operator and farmland returns are below $300 per acre for the medium and high yield scenarios. The highest returns occur in the drought scenario.
Expectations on yield and projected price serve as beginning points for evaluating potential return outcomes. An expected corn yield of 195 bushels per acre is used, matching expectations for high productivity farmland. The 2014 projected price, which will be used to set crop insurance guarantees, will be the average of settlement prices of the December 2014 Chicago Mercantile Exchange (CME) corn contract during the month of February. Given current levels of the CME corn contract, $4.80 per bushel is used as the 2014 projected price.
The 195 bushels corn yield and $4.80 corn price center yield and price expectations. Alternative outcomes are estimated based on yield and price changes for the years from 1975 through 2012. For yields, trend yields are calculated for Illinois for each year from 1975 through 2012. Then, actual yields are stated as a percent of trend yields. In 2012, for example, the trend yield is 163 bushels per acre and the actual yield is 105 bushels per acre. This gives actual yield as a percent of trend of .65 (105 actual yield / 162 trend yield). If a year like 2012 occurs in 2014, the resulting yield is 127 bushels per acre (127 = 195 expected yield x .65 actual yield as a percent of trend)
Harvest prices are divided by projected prices to arrive at price changes. In 2012, the projected price is $5.68 per bushel and the harvest price is $7.50, resulting in a change of 1.32 ($7.50 harvest price / $5.68 projected price). For this analysis, a year like 2012 in 2014 results in $6.34 harvest price ($6.34 = $4.80 projected price x 1.32 harvest price as a percent of projected price). Note that the $6.34 harvest price is considerably below the actual 2012 harvest price of $7.50. This occurs because the 2014 projected price will be considerably below the $6.58 projected price for 2012, likely indicating a different level of stocks and demand in 2014.
The outcomes from 1975 through 2012 are grouped into scenarios. Reported below are three of the scenarios that represent the range of returns that can occur in 2012:
- The drought scenario is based on yield and price changes from the three years with the lowest yields as a percent of trends between 1975 and 2012: 1983, 1988, and 2012. During these three years, yield as a percent to trend yield averages .63 and harvest price as a percent of projected price is 1.29 (see Table 1). Using these factors, a drought year results in a yield of 123 bushels per acre (195 expected yield x .65 actual yield as a percent of trend yield) and a harvest price of $6.19 per bushel ($4.80 projected price x 1.29 harvest price as a percent of projected price).
- The median scenario contains yield and price changes for the ten yield changes that are in the middle of the 1975 through 2012 distribution: 1976, 1977, 1978, 1990, 1996, 1998, 1999, 2000, 2001, and 2010. This median scenario represents an average year. Yield as a percent of trend averages 1.01 during these years (see Table 1). The corresponding average of harvest prices as a percent of projected prices is .92. Given the 195 expected yield and $4.80 projected price, the resulting yield is 197 bushels per acre (197 x 1.01) and the harvest price is $4.42 per bushel ($4.80 x .92).
- The high yield scenario includes years where actual yields exceed trend yields by 10%: 1975, 1979, 1981, 1982, 1985, 1986, 1992, 1994, 2003, 2004, 2007, and 2008. During these years, yields as a percent of trend yield averages 1.13 and the harvest price is .85 of the projected price. Given expectations, the yield is 220 bushels per acre (195 x 1.13) and the harvest price is $4.08 per bushel ($4.80 x .85).
