Why Did Chicago Wheat Lose Its War Premium?

The quick answer

Chicago wheat futures have fallen about 20% from last month's three-year high and slipped back to test the 200-day moving average.

The trigger was Russia agreeing to join Black Sea peace talks, which took the war premium out of the board.

Black Sea shipments are still running at roughly half of normal, so the market priced in peace before there is a deal.

What happened

Chicago soft red winter (SRW) wheat futures are down about 20% from last month's three-year high.

December wheat settled at $6.43¼/bu on October 20.

Early on October 21 it traded down to about $6.21/bu, right where the 200-day moving average sat on my daily nearby chart.

By October 22, December wheat settled at $6.28¼/bu, back to July levels.

By Friday, October 24, all three U.S. wheat boards had slid for the week, with SRW at $6.25/bu, Kansas City hard red winter at $6.64½/bu and Minneapolis spring wheat at $6.41½/bu.

Improved moisture on the U.S. Plains added to the pressure.

The trigger

Russia agreed to join Black Sea peace talks.

The market read that as a sign Black Sea grain will move more freely, and the risk premium that had been built into prices came out.

The war premium leaves faster than it came.

The board priced in peace before there is a deal

SovEcon's Andrey Sizov says Black Sea shipments are still running at roughly half of normal.

Talks are not a treaty.

Ships that are not sailing do not much care what the futures board thinks.

Behind those slow shipments sits a record pile of Russian and Ukrainian wheat, which I covered in Why Are Russia and Ukraine Sitting on a Record Wheat Pile?

What the chart says

The chart with this post is my October 21 Grain Report Chart of the Day: CBOT SRW wheat, daily nearby, testing the 200-day moving average.

Price is well below the 30-day and 50-day moving averages after the slide from the September high.

The 200-day is where a lot of traders look for buyers to show up.

Price has memory.

When I posted the chart, my read was that several factors point to a rally, and the 200-day test is one of them.

That is a chart observation, not a recommendation.

What it means for Prairie growers

Prairie wheat bids take their cues from Minneapolis and Chicago.

When the war premium comes out of Chicago, Prairie bids feel it too.

The flip side is that a premium can come back just as fast if talks stall.

What to watch

• Progress or setbacks in Black Sea peace talks
• Actual Black Sea export pace, not just the headlines
• Whether Chicago wheat holds or breaks its 200-day moving average
• U.S. Plains moisture and winter wheat conditions
