Key Takeaways
- • US corn planting acreage faces potential decline of 1–1.5 million acres to 93.5–94.0 million acres in 2026, driven by record-high planting costs exceeding $900/acre and drought-affected farmers electing to collect Prevent Plant insurance payments rather than assume planting risk beginning May 25th across Texas, Oklahoma, Kansas, and Nebraska.
- • China tariff negotiations remain pivotal for US grain exports: CBOT corn futures await confirmation that China will reduce import duties on US grains to zero, triggering expected Tariff-Rate Quota (TRQ) purchases of US corn and sorghum that could support prices currently under pressure.
- • Sorghum displacement of corn continues at Southern Plains ethanol facilities, with interior sorghum basis holding weak at $0.94 under after improving from $1.20 under over the past two weeks, reflecting historical basis weakness and substitution dynamics at processing plants.
- • CBOT corn futures ended slightly weaker despite anticipation of positive developments from US-China trade discussions, signaling market caution and price sensitivity to confirmation of duty reductions.
Summary
CBOT corn futures experienced modest weakness on May 20, 2026, as traders awaited confirmation that China would eliminate tariffs on imported US grains. The market's directional sentiment hinges on whether preliminary US-China trade discussions develop into concrete tariff reductions, particularly the elimination of duties that would unlock Tariff-Rate Quota purchases of US corn and sorghum. Such purchases would provide meaningful support to a market facing headwinds from domestic supply and acreage dynamics.
Domestic planting decisions are being reshaped by economic pressures. US corn seeding estimates are declining as farmers in drought-affected regions of the Plains confront an unfavorable risk-reward calculus. With corn planting costs now exceeding $900 per acre—at record levels—and Prevent Plant insurance claim deadlines beginning May 25th across Texas, Oklahoma, Kansas, and Nebraska, many producers have indicated to the Agricultural Risk Coverage program that they will elect insurance payments rather than absorb planting risk. Current forecasts suggest 2026 US corn seeding could contract by 1.0 to 1.5 million acres, potentially settling in the 93.5–94.0 million acre range.
Regional basis levels reflect typical seasonal patterns with limited volatility. River terminal basis evolution remains unremarkable and broadly aligned with historical norms. However, interior sorghum basis continues to track weak, currently at $0.94 under after improving modestly from $1.20 under two weeks prior. This weakness supports ongoing sorghum substitution for corn at Southern Plains ethanol facilities, a dynamic that historically constrains corn demand during periods of relative sorghum affordability.
The market remains balanced between supportive trade policy developments and domestic acreage headwinds. Confirmation of Chinese tariff elimination would likely provide upside price support, but domestic planting intentions suggest constrained corn acreage may already be priced into forward-curve expectations.
