• Soybean crush spreads remain modest, oil at 38.3% and meal 23.6%.
• Corn prices firmed, driven by strong demand and bullish fundamentals.
• Corn crush spread widens to 27.8%, indicating tighter margins.
• Wheat climbs above $6, but abundant global stocks limit breakout.

Summary

The grain market update for March 18, 2026 highlighted a mixed day for soybeans while corn and wheat futures posted gains. Soybean contracts traded within a narrow 17.25‑cent range, ending near the previous limit‑down level at 1,162 cents, with July contracts touching 1,177 cents. The soybean crush spread stayed modest, showing a 22.2% overall spread, with oil at 38.3% and meal at 23.6%, and option activity was limited, seeing only about 1,400 puts sold.

Corn prices firmed on bullish fundamentals and strong demand, lifting May contracts 10.75 cents to 464.5 cents and July to 476 cents. Open‑interest activity was more pronounced, with 5,400 call options and 3,000 puts sold, though net positions remain call‑heavy. The corn crush spread widened to 27.8%, suggesting tighter processing margins.

Wheat futures rose above the $6 per‑bushel threshold, with May contracts up 17.25 cents to 607.25 cents and July to 618.25 cents, buoyed by limited Midwest rains. Despite the rally, wheat remains confined within a long‑standing price channel, and abundant global stocks—reflected in a 37.6% crush spread—could cap further breakout. Option interest added roughly 1,000 puts, while total call‑put balances lag behind corn.

The mixed soybean action, firming corn, and wheat’s tentative advance underscore a market awaiting fresh supply‑demand catalysts. Traders will monitor weather developments, export data, and policy news for potential shifts, while the current spreads suggest modest profitability for crushers and processors.

Original Description

Virginia McGathey reviews a relatively quiet session in the grain markets as Soybean futures remained mixed. Prices stayed within the previous range, holding near levels seen earlier in the week while waiting for fresh news catalysts. Corn futures found support on strong demand and bullish fundamentals, managing to recover from an earlier lower start. Wheat futures gained ground following limited rainfall in the Midwest, though prices remain within a two-week channel as plentiful global stocks limit upside momentum. McGathey also details the latest CVOL readings and open interest shifts across the complex.
