US Wheat Protein Spread Narrowing

The spread between December 2026 HRW (Kansas) and SRW (Chicago) wheat is narrowing again.

After Black Sea escalations hit Russian and Ukrainian exports, Kansas wheat gained over Chicago. The logic was simple: Black Sea is high-protein supply. When it goes offline, buyers pivot to U.S. HRW as a substitute, while SRW benefits less.

The contracts rallied into late August, but the KW-W spread peaked much earlier - a classic warning that the premium was about logistics, not shortage.

Since September, Kansas has corrected harder than Chicago. The spread has lost significantly.

Is the world getting comfortable with the conflict? Partly. The market now prices a disrupted flow, not a total shutdown. Ukraine is moving grain via Danube, rail, and Constanta; Russia is still pushing volumes through Baltic ports.

If grain keeps moving at 60-70% of normal, the spread compresses further. If a vessel is hit, it blows out again. For now, traders are pricing a delivery problem, not a wheat shortage.
