The expectation that central banks might come to the rescue in a deepening climate crisis was evidently grounded in an ephemeral conjuncture, which came to an end with Donald Trump’s return to the White House last year. Yet even if this push had succeeded, it may have had difficult side effects. As Yannis Dafermos argued, ‘‘attempts of private finance to protect itself from climate risks’’—and attempts by monetary authorities to push them to do so—may exacerbate climate finance injustice by increasing borrowing costs faced by Global South countries and deepening their financial vulnerability.
Research on the role of global capital in the climate crisis must therefore consider the impacts of corporate concentration on country-level politics, investigating the alliances built by transnational corporations with domestic elites and the potential resistance they may encounter. Seen through this lens, the case of the South American soy boom offers useful insights. Since the late 2010s South America has been responsible for more than half of global soy production and almost two-thirds of global exports of the commodity. In 2024, Argentina, Brazil and Paraguay accounted for 61 percent of all exports.
The data made available by Trase.earth is clear about the dominance of the giant grain traders in Brazilian and Argentine soy exports, as shown in the figures below. (Data includes soybeans and “the raw equivalent of the traded sub-products,” that is, ‘‘soy cake and soy oil are converted to soybean equivalent tonnes”.) Statistics for Brazil start in 2004, when the ABCD firms responded for 48.2 percent of total soy exports, in tonnes. By 2009, their share had peaked at 59.8 percent, before gradually falling over the following years, to 42.2 percent in 2022—the most recent information available. Despite the decline, the four companies remained in control of a sizable share of a booming business: in 2022, exports totalled 93.7 tonnes of soy, up from 36.2 in 2004. The data for Argentina is limited to the period between 2015 and 2019 and shows that the share of the ABCD firms oscillated between a quarter and a third of the total. Adding a fifth giant commodity trader, Glencore, brings this figure above 40 percent.


Founded either in the 19th or in the early 20th century, the ABCD firms saw their global influence increase at the turn of the millennium in parallel with the expansion of future trading in commodities. Jennifer Clapp argued that this financialization of the commodity trade allowed them to “wield enormous power in shaping food systems.” Profiting from volatility that caused hunger and popular rebellions throughout the world, these corporations were known, according to Gustavo de Oliveira and Mindi Schneider, for “rerouting cargo ships mid-ocean to gain marginal profits on large volumes, and speculating on futures markets with the privileged information that results from controlling significant shares of non-transparent markets.”
In South America, their dominance was established in the 1990s through the surge in acquisitions that formed part of the process of neoliberalization. By extending the subordination of soy farmers, they set in motion a cumulative process that further tightened the companies’ grip. They squeezed prices paid to producers and so pushed them to combine intensive use of herbicides with genetically-modified seeds, “in order not to incur price deductions at the point of delivery, deepening the technological treadmill and the farmers’ need for finance.” By the early 2000s, they had come to control“the entire transportation logistics…as well as the port terminals, cargo ships and processing facilities that ultimately crushed the soybeans into meal and vegetable oil.”
South American big capital did not put up much resistance to this trend. In Brazil, Amaggi maintained its powerful position, controlling more than 8 percent of soy exports from Brazil in 2022 and around 1.6 percent of the soy croplands in the mid-2010s, partly by coordinating with the global traders. It established joint ventures with Bunge and Dreyfus and obtained funding from Mitsui (a large Japanese trader). It also had significant political influence. Its owner, Blairo Maggi, was governor of the main soy growing state in Brazil (Mato Grosso) between 2003 and 2010, senator between 2011 and 2016, and Minister of Agriculture between 2016 and 2019.
In Argentina, taxes on exports of unprocessed soybeans, strengthened large domestic agro-industrial capitalists who produced soy oil, allowing them to keep a share of total exports similar to the one of the ABCD firms (see figure above). The three largest Argentine corporations (Vicentin, AGD, and Perez Companc) controlled from a quarter to a third of total exports, between 2015 and 2019. (Embroiled in a series of scandals after 2019, Vicentin would eventually be rescued by an Argentine businessman with the support of Cargill.)
Chinese state capital posed a more significant challenge. Following the so-called “2004 soybean crisis” in China, when a sudden change in the global price of the commodity pushed a number of Chinese processing firms into bankruptcy, the ABCD firms saw their control of the Chinese market surge. In response, the government prioritized the growth of Chinese traders, especially COFCO, in a dispute dubbed the “battle of the beans.” (See Tomaz Fares’ detailed account.) The ripples were eventually felt in South America: in Brazil, COFCO started exporting soy in 2005 and, since 2014, became responsible for a share between 5 and 8 percent of total exports; in Argentina, its share was even higher, around 10 percent, between 2015 and 2019. A substantial part of the post-2009 decline in the share controlled by ABCD in Brazil is explained by the rise of COFCO. Yet the shift in market shares may exaggerate the actual challenge. Being treated initially with “particular hostility” from the ABCD, who aimed “to maintain their oligopolistic control over soybean exports,” COFCO was forced to build alliances with the incumbents, reaching a preferential agreement with ADM. If you can’t beat them, join them.
