# El Niño reduces river cargo capacity in the Northern Arc and drives down grain truck freight rates

> El Niño-related drought and heat have lowered water levels on Brazil’s Madeira and Tapajós rivers, forcing grain shippers to reduce barge loads and adjust convoy operations. Tapajós is operating at 60% of capacity, while reduced grain movements during the off-season have helped push truck freight from Sinop to Miritituba down from R$307.63 per tonne in June to R$255.87 in October.

## Why it matters

Lower river capacity could constrain soybean and corn shipments through a corridor responsible for a large share of Brazil’s exports, potentially tightening export availability. At the same time, weaker seasonal demand for trucking has lowered freight rates on the route.
