March is a big month in the grain sectors; spring planting preparations are underway and market-moving reports and crop conditions around the world could cause major shifts in corn and soybean prices and potential last-minute acreage adjustments as farmers work to maximize crop revenue. Especially with the latest estimates showing tight grain stocks through 2021 and into 2022, this month’s global grain supply/demand and prospective planting data from USDA will do a lot to paint the market picture moving through the growing season. While it’s half a world away, crop weather in Brazil is also expected to influence U.S. grain prices, as any issues with that nation’s crop development could fuel even more upward momentum in prices here. And while corn and soybean prices have slid slightly recently, seasonal factors show the minor correction could be fundamentally setting up another grain rally this summer. See the four things for grain farmers to watch in March.
