The cotton trade has concentrated on Brazil (the US Department of Agriculture expects it to lead world exports for a fourth consecutive year in 2026/27, with 35% of the total), and the El Niño now forecast threatens the Centre-West, where most of that cotton is grown. Countries responsible for around half of global cotton production are expected to face extreme weather this season. The USDA's September estimates put Brazil's own ending stocks for 2026/27 about 11% lower, at 3.2 million bales. The leading exporter is set to finish this shipping season with less in reserve.
The last El Niño tested the same region. November 2023 was the hottest and driest November in 30 years in Mato Grosso, the leading cotton state, and Imea, the state's agricultural economics institute, later projected its 2023/24 cotton yield 6.42% below the previous season's record. The national crop grew regardless, helped in part by farmers who shifted acreage to cotton instead of replanting drought-hit soybeans. Conab, Brazil's crop agency, put planted area up 16.9% to 1.94 million hectares, and the growers' association Abrapa projected output up 12.2% to 3.5 million tonnes. Area expansion carried that harvest through the yield loss.
Supply from a major producer has also been withdrawn by government decision overnight, and only partly restored a week later. India banned cotton exports on 5 March 2012 and partly lifted the ban on 12 March, allowing only shipments that had already been registered. Contracts not yet registered stayed blocked, so the reversal was incomplete.
Brazil's buyers are spread across Asia and Turkey. In the 2025/26 marketing year, according to export data reported in August, China took 770,523 tonnes, 23% of the total, followed by Bangladesh (17%), Turkey (13%), Pakistan and Vietnam (12% each) and India (10%). China's purchases rose by 309,200 tonnes, partly because extra tariffs had made American cotton less competitive there. Six markets took about 87% of Brazil's shipments.
If this El Niño cuts yields without the area growth of 2023/24, those six buyers will bear the loss on very unequal terms.
