Where do soybeans come from?

The soybean is a warm-season legume that sets its crop during long summer days and wants steady rain through flowering and pod fill. It was domesticated in northern China, but the countries that grow it at scale are in the Americas, where flat land, deep soils, cheap fertilizer-free nitrogen (the plant fixes its own) and full mechanization make it the most profitable way to use a summer field. In 2024 Brazil produced 144.5 million tonnes, 36% of the world's 397.7 million tonnes (FAOSTAT). United States grew 118.8 million tonnes (30%) and Argentina 48.2 million tonnes (12%); the top five countries accounted for 87% of the crop.

Brazil's rise is the story of the last fifty years. Public breeding at Embrapa produced varieties that flower at low latitudes, lime and phosphate corrected the acid soils of the Cerrado savanna, and cheap land in Mato Grosso, Goiás and the new frontier of Matopiba let farms expand in blocks of thousands of hectares. Output in Brazil grew at +5.2% a year over the decade to 2024, against +1.1% in United States (FAOSTAT). A second crop of corn planted straight after the soybean harvest in January and February pays for the land twice.

The United States grows soybeans in rotation with corn across Illinois, Iowa, Minnesota and the rest of the Corn Belt, with the Mississippi river system to carry the crop to the Gulf. Argentina's crop sits on the humid Pampas around Rosario, which is also where most of it is crushed. Behind those three come China and India; China, the crop's home, grows a large area of food-grade beans but imports many times more for crushing. Ten years of expansion lifted world output by +30% to 2024.

Soybeans are the most valuable farm product in world trade, and the flow is unusually lopsided: three exporters, one importer. In 2024 exports of soybeans (HS 1201) were worth $80.5 billion (CEPII BACI). Brazil shipped 54% of that value and United States 31%, with Paraguay a distant third. On the buying side China alone took 59% of world imports, most of it whole beans for its own crushing industry, followed by Mexico and Argentina.

Argentina looks small in the bean table because it crushes at home and exports the products. Argentina was the largest exporter of soybean meal (HS 2304) in 2024 with 28% of the value, and Argentina led soybean oil (HS 1507) with 45% in 2024. Meal goes mainly to feed compounders in Europe and Southeast Asia; oil goes to India, North Africa and, increasingly, to biofuel plants. Whether a country sells beans, meal or oil depends on its crush capacity, its export taxes and the wishes of its largest customer.

The reference price is the Chicago Board of Trade soybean future (ticker ZS, 5,000 bushels, quoted in US cents per bushel; a bushel is 60 pounds or about 27.2 kilograms). CBOT also lists soybean oil (ZL, 60,000 pounds, US¢/lb) and soybean meal (ZM, 100 short tons, US$/short ton), and the three together let a crusher lock in the "board crush", the margin between beans bought and products sold. Every physical trade is quoted as a basis to the nearest Chicago contract: a Brazilian cargo might be offered at Paranaguá as a premium or discount to the March future, and a Gulf of Mexico cargo as a premium to the same month.

The World Bank's series, which this page uses, is US, CIF Rotterdam, a delivered price for US beans at the main European import port. In August 2026 it stood at $482/t, up 18% from a year earlier (World Bank Pink Sheet). Its nominal record was $737/t in June 2022, and its low since 1960 was $88/t in October 1960. Products are quoted separately: Soybean oil, Dutch FOB ex-mill was $1,638/t and Soybean meal, Argentine 45-46% CIF Rotterdam was $403/t in the same month. A CIF quote includes freight and insurance to the destination port; an FOB quote does not, so the gap between Rotterdam CIF and a Gulf or Paranaguá FOB is mostly ocean freight.

Quality terms are simpler than for grains: contracts specify moisture, foreign material, damaged kernels and, for crushers, oil and protein content, which vary by origin and season. Two ambiguities matter. First, "soybean prices" can mean beans, oil or meal, and they often move in different directions when biofuel policy lifts oil while a big crush weighs on meal. Second, production on this page is beans as harvested, while USDA's balance sheet runs on marketing years that start in September for the United States and in the following January or February for South America.

Brazil plants from September and Argentina from October, so the northern-hemisphere winter is the southern crop's growing season. La Niña tends to bring drought to Argentina and southern Brazil, El Niño excess rain at harvest; either can cut yields in the countries that supply most of world exports. Because South America's harvest lands in the first half of the year, its weather sets the price for the second half of the US marketing year.

American farmers choose each spring between corn and soybeans on much of the same land, and the ratio of new-crop soybean to corn futures, together with fertilizer costs, tips the decision. A ratio well above 2.5 pulls acres toward soybeans. Planting intentions and the June acreage report from USDA are therefore market events in their own right, before a single pod has set.

China buys most of the world's traded beans to make meal for pigs and poultry and oil for cooking. The size of its hog herd, the recovery from African swine fever after 2018, feed-ration rules that cap soymeal inclusion, and the timing of state-reserve purchases and auctions all show up in Chicago within days. Chinese crush margins, quoted daily in Dalian, are watched as a proxy for near-term import appetite.

The stocks-to-use ratio, ending stocks divided by consumption, is the market's shorthand for how tight supply is. USDA put world soybean stocks-to-use at 29% for 2026/27, against 30% in 2025/26 (USDA PSD). Traders watch the US ratio more closely than the world figure, because US stocks are the ones that can be shipped at short notice; a US ratio in single digits has coincided with the sharpest price spikes.

Soybean oil is the main feedstock for US biodiesel and renewable diesel, so the Environmental Protection Agency's blending volumes, the 45Z production credit and state low-carbon fuel standards set a floor under oil demand. Brazil's biodiesel blend mandate, raised in steps through the 2020s, does the same at home. When policy lifts oil, crushers run harder and meal becomes the byproduct, which pushes meal prices down and can lift bean demand while depressing product margins.

China's 25% retaliatory tariff on US beans in July 2018 cut US shipments to China by about three-quarters within a year and redirected Chinese demand to Brazil; the 2020 Phase One deal and the November 2025 purchase commitment partly reversed the flows. Argentina taxes bean exports more heavily than meal and oil, which is why it crushes at home. The EU deforestation regulation adds a traceability cost to Brazilian and Paraguayan beans. Each rule changes which origin is cheapest for a given buyer rather than the world balance.

Brazilian farmers sell in dollars and pay costs in reais, so a weaker real raises their local price and encourages both selling and planting; a strong real does the opposite and slows farmer sales, tightening port premiums. Argentina's gap between official and parallel peso rates, and periodic 'soy dollar' schemes offering farmers a better rate, decide when the Argentine crop comes to market.

Soybean oil competes with palm, rapeseed and sunflower oil in food and fuel, and soybean meal competes with rapeseed meal, corn distillers' grains and fishmeal in feed. When Indonesian palm exports are restricted, as in 2022, soybean oil rallies with them; when Ukraine's sunflower oil returns to market, it weighs on the whole vegetable-oil complex. Bean prices follow the weighted value of the two products they contain.

Soybeans are sown in spring in the United States (late April to June) and in the southern spring in South America (September to December), and harvested about four to five months later. Varieties are grouped by maturity to match day length at each latitude, and almost all of the commercial crop in the three big exporters carries herbicide-tolerant or insect-resistant traits introduced from 1996 onward. Non-GM, identity-preserved beans are a small premium market for tofu, natto and soy milk, mostly grown under contract for Japan, Korea and Europe.

A combine strips the pods and threshes the beans, which are dried to about 13% moisture, stored in silos or bags and moved by truck, rail and barge. The crop's value is unlocked at the crusher. Beans are cleaned, cracked, dehulled and rolled into flakes; hexane extracts the oil, and the defatted flakes are toasted and ground into meal. A tonne of beans yields roughly four-fifths meal and a little under a fifth crude oil, plus hulls that go into cattle feed. Mechanical expeller presses do the same job at smaller scale and leave more oil in the meal.

Crude soybean oil is degummed (which yields lecithin), refined, bleached and deodorized for the table, or sent to a biodiesel or renewable-diesel plant. Meal is sold by protein content, typically 44% to 48%, and hipro Argentine meal is the benchmark grade in Rotterdam. Because the products are worth more than the bean, crush margins, not bean prices alone, decide how fast the crop is processed and where.

Most of the world's soybeans are crushed, and most of the meal feeds chickens, pigs, dairy cattle and farmed fish, which is why soybean demand tracks meat consumption rather than direct human eating. The oil is the second most used vegetable oil after palm: it fries food, fills bottles of cooking oil, goes into margarine and mayonnaise, and, in the United States and Brazil, into diesel substitutes under blending mandates. Whole beans become tofu, soy milk, tempeh, natto, edamame and soy sauce, mostly in East Asia, and lecithin from oil refining is an emulsifier in chocolate and baked goods. Industrial uses include inks, adhesives and polyols for foams.

Crushing concentrates where beans and feed demand meet. China has the largest crush industry, built along its coast to receive imported beans; Argentina's plants line the Paraná above and below Rosario and ship meal and oil from the same docks; the US Midwest and Brazil's Mato Grosso and Paraná states process for domestic feed and export. Independent crushers matter, but four merchants, Archer Daniels Midland, Bunge, Cargill and Louis Dreyfus, together with COFCO and Viterra (part of Bunge from July 2025), own much of the world's crush and export elevator capacity.

Brazil's crop leaves through Santos and Paranaguá in the south and, in growing volume, through the "Northern Arc" ports of Itaqui, Barcarena and Santarém, reached by the BR-163 highway and the Tapajós river. US beans travel down the Mississippi and Illinois rivers by barge to Gulf elevators near New Orleans, or by rail to Pacific Northwest terminals for Asia. Argentine exports depend on the depth of the Paraná below Rosario, which in 2021 fell so far that ships loaded a sixth less than usual.

The chokepoints are rivers and roads: Mississippi low water in the autumns of 2022 and 2023, Paraná droughts, Brazilian truck strikes and unpaved sections of BR-163 in the wet season, and the Panama Canal's draft limits during the 2023 drought. The demand-side single point of failure is China, which takes most of the traded crop; any change in its tariffs, reserve purchases or hog herd reshuffles the whole map.
