  • Rethinking Fertilizer Prices

    Rethinking Fertilizer Prices

    Although the Russian war with Ukraine has been pinpointed as the leading cause of high fertilizer prices, the price of nitrogen fertilizer began to increase in May of 2021, long before Russia invaded Ukraine on February 24, 2022. The increases in fertilizer prices in 2021 were caused by supply and demand factors. On the supply side, increases in natural gas prices and shipping costs likely influenced fertilizer prices (Smith, 2022). Additionally, corn futures prices increased drastically in May 2021, incentivizing farmers to apply more nitrogen per acre. Following nitrogen application, fertilizer prices dropped slightly before increasing again in February of 2022 due to the Russian invasion of Ukraine, which caused supply chain disruptions in nitrogen fertilizer exports. Since September, fertilizer prices have dropped significantly. In this article, we reframe fertilizer prices to look more closely at the recent declines in fertilizer prices. Specifically, we focus on the fertilizer price to new crop corn futures ratio. Using this ratio, we can frame fertilizer prices in a form allowing us to account for fertilizer and corn prices.

    Figures 1, 2, and 3 show the plotted ratio of fertilizer price to new corn futures ratio for NH3, urea, and UAN from 2020 to early March of 2023, respectively. Unsurprisingly for all three commodities, the lowest ratios occurred before the price increases in 2021. Following the 2021 price increases, the impact of the Russian-Ukrainian war sustained an already high nitrogen price. The red line in each graph depicts the 2023 nitrogen price relative to the price of corn. For UAN and urea, the ratio of fertilizer to new crop corn price has fallen below the 5-year average levels, whereas the price of NH3 is still slightly above the 5-year average. These results may indicate that ammonia fertilizers are still unreasonably high due to Russia being the second largest NH3 exporter, behind Trinidad and Tobago (World Bank, 2021).

    Figure 3. UAN Price Relative to New Crop Corn Futures

    As the ratio for NH3 remains above the five-year average, it may be time to look at alternative nitrogen sources. One nitrogen source of interest is urea, the nitrogen source furthest under the 5-year average. The average price of nitrogen/pound of urea is historically higher than that of NH3. However, this season, the current price per pound of nitrogen from both sources is similar, making the switch from NH3 to urea more appealing. If in-season nitrogen application is needed, the relative price of urea is historically lowest in June. However, it is worth noting that an escalation in Ukraine or a discontinuation of the Black Seas Grain Deal would likely cause the price of each nitrogen source to increase.

  • Sensitivity of USDA’s Agricultural Outlook Forum Projections to Changes in Soybean Crush Demand

    Sensitivity of USDA’s Agricultural Outlook Forum Projections to Changes in Soybean Crush Demand

    At the Agricultural Outlook Forum in late February, the USDA released its first supply and demand projections for the 2023 crop year. In the March 20th issue of Southern Ag Today, we looked at how changes in corn exports could change the stocks-to-use (STU) ratio and, thus, price. In this article, we perform a similar analysis for soybeans. Specifically, we find that the soybean STU is much more sensitive to changes in demand than corn. Results indicate that a miss-projection of domestic crush levels could significantly affect soybean STU and price. Although we focus on soybean crush in this article, results would be the same for other increases in demand, such as exports or other domestic products. 

     As mentioned in our previous article, STU is a fundamental indicator in commodity marketing, as it compares commodity ending stocks to commodity demand. The impact of missed projections on STU provides insight into each commodity’s supply and demand dynamics (Gardner and Smith, 2023). Plot A of Figure 1 shows the year and soybean marketing year average price at various levels of STU. Generally, we would expect a larger STU to indicate more supply than demand which would cause a lower price and vice versa. From 2011 to 2013, supply was short due to below trend line yields or lower harvested acres, thus causing a shortage relative to demand that resulted in higher prices. Lower STUs and prices occurred in 2014 and 2015 due to increased acres (5 million acres more were harvested in 2014 and 2015 than in 2013) and a return to trend line yields. Since 2016, domestic crush capacity has increased substantially (CME Group).

    Figure 1. Stocks-to-Use (STU) Ratio and Price by Year and Impact of Missed Soybean Crush Projections on STU

    Plot B of Figure 1 displays the potential impact of an under-projection of soybean crush on STU, holding other factors constant. The American Soybean Association projects U.S. soybean crush capacity in 2023 to increase by close to 64 million bushels in 2023 (460 million bushels of increased capacity by 2025); however, the EPA is only assuming an increase in crush demand of close to 45 million bushels (Gerlt, 2023). This difference between increased crush capacity and crush demand could result in an underestimation of projected soybean crush in 2023. If soybean crush is underestimated, an increase in crush numbers of 5 million bushels lowers soybean STU by 0.12%, indicating that soybean STU is more sensitive to demand shocks than corn. If crush expansion and demand are met, soybean STU could quickly move lower than 6%, indicative of 2022, in which the soybean price was $14.30. 

    Changes in projected supply and demand will impact soybean STU and, consequently, the marketing year average price. The USDA current marketing year average soybean price for 2023 is projected to be $12.90, but if biodiesel capacity expansion increases soybean demand, the marketing year average price could be higher in 2023. Soybean prices could also increase with a rise in export demand or a supply shortage. Producers and traders should be mindful of projected changes in STU and use this information as one factor that could influence price expectations for the upcoming crop.

  • Sensitivity of USDA’s Agricultural Outlook Forum Projections to Changes in Corn Exports

    Sensitivity of USDA’s Agricultural Outlook Forum Projections to Changes in Corn Exports

    Supply and demand projections for the upcoming 2023 crop year were released at the USDA’s Agricultural Outlook Forum on February 23. In the March 6th issue of Southern Ag Today, we looked at how close previous projections have been to final USDA estimates for corn, soybeans, and wheat. In this article, we expand upon missed projections and look at how changes in corn demand from the USDA’s projections could affect the stocks-to-use (STU) ratio and, thus, price. The simple analysis gives us insight into the supply and demand dynamics for the upcoming crop year. Specifically, we focus on changes in corn exports.  China, the largest importer of U.S. corn last year, cleared more Brazilian firms for corn export on March 6th to ease their dependence on U.S. imports (FAS, 2023; Samora, 2023). Additional access for Brazilian corn to China could reduce U.S. corn exports.

    STU is a fundamental indicator in commodity marketing as it compares commodity ending stocks to commodity demand. The impact of missed projections on STU provides insight into each commodity’s supply and demand dynamics. Plot A of Figure 1 shows the STU and marketing year average price for corn by year. The main takeaway from Plot A is that a higher STU indicates lower demand relative to supply and, thus, lower prices, whereas a lower STU shows higher demand relative to supply and higher prices. For example, in 2012, the drought impacted the supply of corn, resulting in lower STU and higher commodity prices. 

    Plot B of Figure 1 looks at the impact of missed export projections by the USDA on STU. In 2023, the USDA is projecting a 15% increase in corn exports from last year (USDA, 2023). Holding all the other USDA corn estimates constant and changing exports, we find that a 100-million-bushel miss-projection in corn exports would change corn STU by 0.39%. 

    As the Brazilian corn crop is projected to hit record numbers, increased Brazilian corn exports could negatively impact U.S. corn demand (Donley, 2023). In 2022, China imported 5.26 billion bushels of corn from the U.S. (FAS, 2023). If these numbers were cut by just 500 million bushels, causing the USDA to over-project exports, corn STU could be higher than 2018 levels when the average corn price was $3.61, assuming the other projections are unchanged. The current average corn price for 2023 is projected at $5.60. If exports are cut, and STU increases, the marketing year average corn price will likely be lower than projected. Changes in projected supply and demand will impact STU for corn, and consequently the marketing year average price. Producers and traders should be cognizant of projected changes in STU and use this information as one factor that could influence price expectations for the upcoming crop.
