The Brazilian government’s decision to withdraw its ambassador from Argentina has intensified a crisis that carries significant political and diplomatic ramifications, while also posing a risk to the economic relationship between the two nations — a relationship that is paramount to Argentina’s foreign trade. Argentina’s bilateral trade relationship with Brazil stands unparalleled globally in terms of significance. According to the latest official data from Indec, Argentina exported US$49 billion in goods in the first half of the year, with US$6.2 billion — 12.6% of the total — directed to Brazil. The primary exports during that timeframe included overland transport equipment valued at US$2.5 billion, followed by cereals at US$562 million, plastics at US$386 million, base metals at US$355 million, and dairy products at US$347 million. The neighbouring country serves as the primary export destination for Argentina’s automotive industry, which stands as the fourth-largest contributor to foreign currency inflows, as well as for its wheat sector, which occupies the fifth position in this regard.
It serves as a crucial market for Argentine dairy, wine, olive oil, pears, apples, and vegetables, ranking as the second-largest destination for the nation’s services exports, surpassed only by the United States. On the import side, Brazil holds the second position in significance, representing 22.3% of the total, trailing only China. The products that Argentina imported from Brazil during the first half of 2026 included processed industrial goods valued at US$1.9 billion, passenger vehicles amounting to US$1.4 billion, parts and accessories for transport equipment totalling US$1 billion, industrial transport equipment at US$658 million, and capital goods reaching US$562 million. The balance is unfavourable for Argentina. The accumulated deficit in the first half of 2026 reached US$993 million, reflecting an improvement from the US$2.9 billion shortfall noted in the first half of 2025. “The result was driven by the jump in exports and by imports, which fell mainly because of the auto sector,” said ABECEB. The Economic Complementation Agreement for tariff-free trade in cars, known as ACE 14, significantly influences bilateral trade, as it constitutes the foundation of economic integration between the two nations.
Signed on December 20, 1990, it has been renewed almost unchanged for 35 years, with the most recent extension, agreed upon in 2019 for a 10-year term, set to expire in June 2029. On both the Argentine and Brazilian sides, there is an anticipation to negotiate a new agreement that will extend the existing framework beyond the specified date, as this scheme has provided a measure of stability to the automotive sectors of both nations. In the realm of foreign direct investment, Brazil occupies the fourth position as a source of capital in Argentina, contributing over 8% of the total. Ahead of it are the United States (18%), Spain (14%), and the Netherlands (12%), under whose flag a significant portion of the investment from the European Union is channelled. “Toyota isn’t going to stop selling pickups in Brazil or stop bringing Corollas from Brazil, and Stellantis isn’t going to stop selling cars in Brazil,” former Production Minister and ABECEB founding partner Dante Sica said.
Sica played down the idea that a “lack of presidential diplomacy” could affect trade and investment flows in the short term, since the two countries “have been building integration processes and consolidating value chains since the 1990s, when Mercosur began to take shape.” He added that even at times when the two countries’ leaders had “more ideological affinity” — as was the case with Alberto Fernández and Luiz Inácio Lula da Silva — some “short circuits at the presidential level” have come up. Nonetheless, Sica recognised that should the situation extend into the following year, complications may arise. “It might start to complicate some consular matters and some negotiations that are under way,” Sica said. One he mentioned is the possibility of extending the pipelines from the Vaca Muerta hydrocarbon fields to supply gas to Brazil, especially the São Paulo region. “Those negotiations, which involve regulatory changes, adapting to standards or the possibility of better market access for products into Brazil that require conformity systems, might be delayed a bit,” Sica said.
