Paraguay's grip on Brazil's corn supply has solidified since 2022

In 2025, Brazil's imports of corn presented a paradox. While the country stands as one of the world's top exporters of the grain, it simultaneously imported US$ 315.7 million worth, with a single partner, Paraguay, accounting for an overwhelming 97.3% of that flow. This isn't a new development, but the culmination of a reliance that has become deeply embedded in the regional economy since 2022.

The concentration is one of the most extreme in Brazil's agricultural trade book. The Herfindahl-Hirschman Index (HHI) for the corridor sits at 0.946 on a scale of 0 to 1.0, signaling a near-monopolistic supply channel. While eight countries shipped corn to Brazil in 2025, their combined volume was a mere fraction of Paraguay's, making them statistically insignificant.

The other side of concentration

This is not a story of arbitrary dependence but of calculated logistics. The heart of Brazil's pork and poultry industry lies in its southern states, particularly Santa Catarina and Paraná. These regions are net consumers of corn for animal feed but are geographically distant from Brazil's own grain belt in the Center-West. Trucking corn over 1,500 kilometers from Mato Grosso is often more expensive than sourcing it from just across the border in Paraguay.

Paraguayan corn farms are, in many cases, closer to Brazilian processing plants than domestic alternatives are. This proximity creates a powerful economic moat, making Paraguayan supply the rational choice for Brazilian importers focused on managing input costs. The relationship is so entrenched that some of Brazil's largest agricultural cooperatives have established their own grain collection and storage infrastructure inside Paraguay, further streamlining this cross-border flow. The corridor is less a matter of international trade policy and more a reflection of ground-level supply chain efficiency.

Alternative routes

What happens if the Paraguayan harvest fails or border logistics seize up? The vulnerability is real, even if the probability shifts year to year. A severe drought in Paraguay, for instance, would send immediate price shocks through Southern Brazil's livestock sector. The primary substitute is Argentina, which holds a distant #2 position in Brazil's import matrix but lacks the scale and seamless integration of the Paraguayan route.

The other alternative is domestic. Importers would be forced to turn to the Center-West, absorbing the steep freight costs they currently avoid. This would squeeze margins for meatpackers and could ultimately translate to higher consumer prices for poultry and pork in Brazil. The paradox remains: even in a year with a bumper 'safrinha' harvest in Mato Grosso, Brazil's south could face a supply crunch if its primary external partner falters. The national supply picture doesn't erase regional deficits.
