CBOT Soybean Weekly Report: Soybeans Volatile, Benchmark Contract Down 5.2%

Chicago, March 22 – As of the week ending March 20, 2026, Chicago Board of Trade (CBOT) soybean futures experienced violent volatility, with the benchmark contract closing down 5.2%, failing to extend its previous six-week upward trend. This was mainly due to concerns over demand triggered by US President Trump postponing his visit to China, as well as seasonal pressure from the arrival of Brazil's bumper soybean crop.

On Monday, soybean futures hit the 70-cent limit down, marking the largest single-day drop in three years, before gradually recovering some losses. The direct trigger for the early-week plunge was President Trump's statement on Sunday that he might postpone his visit to China to pressure China into helping open up the Strait of Hormuz. This statement sparked concerns about China's prospects for purchasing US soybeans. Analysts pointed out that a delayed summit means a delayed trade agreement, and delays often carry the risk of changing circumstances. Although talks between US and Chinese officials in Paris were described as "exceptionally stable," and China still committed to continuing purchases of US soybeans under the framework of the October 2025 trade truce agreement, market sentiment was significantly impacted.

Mid-week, market sentiment gradually repaired. Trump confirmed on Tuesday that the meeting with Chinese leaders would be rescheduled for five to six weeks later, alleviating excessive concerns about trade prospects. Meanwhile, geopolitical factors provided support for soybean prices. The escalating war in Iran boosted crude oil prices, and soybeans, as a raw material for biofuels, are closely linked to the energy market. News that Trump invited farmers and biofuel producers to a White House event on March 27 also boosted optimistic expectations for biofuel blending quota policies.

The USDA Export Sales Weekly Report showed sluggish US soybean sales. As of the week ending March 12, net sales of US soybeans for the 2025/26 marketing year were nearly 300,000 tons, a 42% decrease from the four-week average. Total sales year-to-date decreased by 18.7% compared to the previous year, while the USDA predicts a full-year decrease of 16.3%. However, soybean crushing performance was good. The National Oilseed Processors Association (NOPA) stated that member companies crushed 208.75 million bushels of soybeans in February, a 17.4% increase year-on-year, exceeding market expectations.

According to a survey of growers by Allendale Inc., US soybean planting area this year is expected to be 85.66 million acres, an increase of 4.46 million acres from last year, and also higher than the USDA's forecast of 85 million acres at its annual forum.

From the perspective of fund holdings, as of March 17, speculative funds held a net long position of 201,997 contracts in soybean futures and options, a decrease of 20,110 contracts or 9% from a week ago.

Below is a review of the futures market over the past week:

Closing on March 20, the May contract was down 64 cents from a week ago, closing at 1161.25 cents/bushel; the July contract was down 61 cents, closing at 1176.50 cents/bushel; the November contract was down 20.5 cents, closing at 1141 cents/bushel.

The CBOT soybean market underwent significant turbulence during the week ending March 20, 2026, erasing gains from the prior six weeks with a 5.2% decline in the benchmark contract. The primary drivers were geopolitical tensions stemming from President Trump's potential delay in visiting China, which raised fears about future trade agreements and Chinese demand, coupled with seasonal supply pressure from Brazil's harvest. While the market initially crashed to a three-year low on Monday, it partially recovered mid-week following confirmation that the US-China summit would be rescheduled rather than cancelled, alongside supportive factors from rising crude oil prices and positive biofuel policy expectations. Fundamental data presented a mixed picture: US export sales remained weak, falling short of averages and previous year levels, whereas domestic crushing activity exceeded expectations. Additionally, prospective planting data suggests an increase in US soybean acreage, and speculative funds reduced their net long positions by 9%.

The soybean market's sharp correction highlights its sensitivity to geopolitical headlines and trade policy uncertainties. Although the immediate panic over the US-China summit was alleviated by the rescheduling news, the underlying bearish pressures remain significant. These include robust Brazilian supplies entering the global market, lackluster US export pace, and forecasts for expanded US planting acreage. However, the market found a floor supported by the energy complex, specifically rising crude oil prices which bolstered soybean values through the biofuel channel. Moving forward, market participants will likely focus on the progress of the rescheduled trade talks, actual implementation of biofuel mandates, and whether the strong domestic crushing demand can offset weak export numbers. The reduction in speculative long positions suggests a cautious stance among investors as the market navigates these conflicting fundamental and macroeconomic signals.
