Acreage Surprise Incoming? What USDA Might Reveal Tomorrow

USDA Acreage Report – June 30, 2026

The much-anticipated USDA release is due tomorrow, where acreage estimates for MY 2026/27 and quarterly stocks as of June 1, 2026 will be published. Historically, this dataset has been a significant market mover, and this year should be no exception.

Market expectations suggest a notable shift in planting trends. Soybean acreage is projected to expand to 85.3+ million acres, largely at the expense of corn, which is expected to decline by nearly 4 million acres compared to last season.

Consensus Estimates vs Historical Data

• Corn: ~94.99 million acres (range: 93.95–96.30) vs 95.34 (March) and 98.79 (2025 final)
• Soybeans: ~85.37 million acres (range: 84.30–86.00) vs 84.70 (March) and 81.21 (2025 final)
• All Wheat: ~43.86 million acres (range: 43.40–44.39) vs 43.78 (March) and 45.33 (2025 final)

Soybean/Corn Ratio – A Key Indicator

When assessing US Spring planting trends, one of the most closely watched indicators is the ratio between CME new crop soybean (SX) and corn (CZ) futures—specifically, the average closing ratio during February.

Over the past two decades, this ratio has ranged between 1.89 and 2.59, consistently serving as a reliable signal for acreage allocation decisions:

• Below 2.25: Corn tends to dominate planting decisions (e.g., 2025)
• Above 2.40: Soybeans become more attractive (e.g., 2017, 2018)

For 2026, the ratio stands at ~2.40, placing it firmly in soybean-favorable territory.

AgPulse View

While the soybean/corn ratio remains a critical driver, it is not the sole determinant of acreage decisions. Factors such as agronomic considerations, crop rotation practices, planting conditions, and geopolitical dynamics—including Chinese demand—also play meaningful roles.

That said, our framework continues to assign significant weight to the price ratio. Given its current level, we expect a shift in acreage from corn to soybeans this season.

Our Estimates:

• Soybeans: ~86 million acres
• Corn: ~94 million acres

Bottom Line:
The upcoming USDA release carries the potential to validate or challenge market expectations of a soybean-led acreage shift. With positioning already leaning in that direction, any deviation could trigger notable price action.
