Chile’s grain market stays stable as rain delays planting and Black Sea risks tighten corn

Global supply remains broadly balanced

Global cereal production is expected to remain stable in the 2026/27 season, although weather disruptions and maritime tensions are complicating the outlook for Chilean growers and grain buyers. The assessment comes from the August 2026 Cereals Bulletin No. 8, prepared by Chile’s National Agricultural Society (SNA) and the Southern Agricultural Consortium (CAS) and reported by La Tribuna.

The completion of the Northern Hemisphere wheat harvest has provided more certainty about available volumes. Attention is now shifting to corn harvests later in the year and to Chile’s domestic planting cycle. SNA and CAS said sustained food demand should continue to provide a market for efficient producers, while also noting that agricultural commodities as a group are not scarce.

Rain delays Chilean wheat planting

Weather is the immediate concern for Chilean farmers. The INIA Agrometeorological Network recorded accumulated precipitation as of August 20, 2026 of 55.3 millimeters in Copiapó and 171.7 millimeters in La Serena, more than 50% above the comparable levels of 2024 and 2025. Accumulated rainfall reached 411.0 millimeters in Valparaíso and 1,082.4 millimeters in Biobío. Farther south, Los Ríos recorded 1,779.8 millimeters and Los Lagos 851.8 millimeters, although rainfall there remained below previous years.

Predictive models cited by La Tribuna point to a wet spring. July rainfall already disrupted fieldwork and postponed intermediate and spring wheat planting. Flooding caused only limited plant losses, but the delays could reduce the total planted area. The risk extends to the central region’s wheat harvest, which begins in December, making field access and crop development important variables for processors seeking domestic grain.

Wheat recovers while corn logistics face pressure

International wheat futures were volatile after falling on the Chicago Board of Trade on June 29, before showing a recovery toward the end of August. The US Department of Agriculture’s WASDE report projected global wheat production of 819.3 million metric tonnes in 2026/27, down 3% from an earlier estimate of 843.8 million tonnes following reductions for the European Union and the United States. La Tribuna reported that the US projection was the lowest in 56 years. Global consumption was estimated at 826.3 million tonnes and ending stocks at 273.2 million tonnes.

In Chile, flour millers are looking for stored wheat. Corn futures, meanwhile, have not followed wheat higher and remain below their late-2025 levels. Fighting involving Russia and Ukraine around the Bosporus, the 30-kilometer passage connecting the Black Sea and the Mediterranean, is creating uncertainty for merchant shipping. The disruption is raising freight rates and insurance premiums and encouraging buyers to consider alternative origins.

Imports cover corn needs as oat sowing slips

WASDE projected global corn production at 1,298.9 million tonnes and consumption at 1,323.0 million tonnes for 2026/27, indicating tighter but still balanced supply. Chilean market activity is focused on imports from Argentina, Paraguay and the United States, while domestic purchases at harvest prices have been limited. The combination leaves importers exposed to changes in ocean logistics even when international futures remain comparatively weak.

For oats, the USDA projected production of 23.3 million tonnes against consumption of 23.5 million tonnes. Chile’s industry processes food-grade oats largely for export, rather than only the feed oats tracked by futures markets. Local sowing in July and August was delayed, and SNA and CAS warned that planting outside the normal window could cause severe yield losses. The sector will gather in Pucón from November 17 to 20 for the OAT 2026 World Conference, which will be held in Latin America for the first time and will showcase southern Chile’s production advantages.
