Survey finds up to 150% price gap for corn across Paraíba state

A price survey conducted by the consumer protection agency of Paraíba state in northeastern Brazil uncovered a gap of up to 150% in corn prices across monitored retail and wholesale points. The finding highlights significant imbalances in local supply chains, logistics, and bargaining power along the grain distribution network. Both buyers and rural producers operating in the region are affected by this level of price dispersion.

The Paraíba state consumer protection office released a corn price survey showing a 150% spread between the lowest and highest prices recorded across monitored establishments. This means the same commodity can cost more than twice as much depending on where it is purchased within the same state, creating uncertainty for buyers who rely on corn for feed or processing operations.

For corn producers selling into the northeastern Brazilian market, wide price dispersion can cut both ways. Farmers with access to multiple sales channels may capture better margins by seeking out higher-paying buyers, while those with limited commercial reach remain exposed to the lower end of the local price range, squeezing their profitability.

The data also points to structural weaknesses in regional grain distribution, including dependence on intermediaries, insufficient storage infrastructure, and inconsistent local supply. These conditions tend to amplify price volatility at both the farm gate and the consumer level, widening the gap between what producers receive and what end users pay.

Systematic price monitoring by public agencies improves market transparency, but addressing the root causes of such distortions requires targeted investment in logistics, on-farm and cooperative storage, and broader access to market price information for producers operating in the region.
