US wheat futures end mixed after sinking to contract lows on big global supplies

CHICAGO, Aug 4 (Reuters) - U.S. wheat futures dropped to contract lows on Monday on ample global supplies, but finished the day narrowly mixed, traders said.

• The U.S. winter wheat harvest was expected to be 88% complete as of Sunday, up from 80% a week earlier, according to analysts surveyed by Reuters ahead of a weekly U.S. Department of Agriculture crop progress report.

• Russian wheat export prices fell last week, tracking a decline in global prices on expectations that markets will be well supplied this year as harvesting in major producing countries advance.

• The 2025 harvest of Ukraine's key commodities, wheat and corn, may be higher than expected if weather conditions are favourable, while stable export demand will encourage farmers to expand winter wheat sowings for the 2026 crop, a senior official said on Monday.

• CBOT September soft red winter wheat WU25 fell to a contract low of $5.13 a bushel but ended unchanged at $5.16-3/4 per bushel. December 2025 through December 2026 contracts also posted lifetime lows on Monday.

• K.C. September hard red winter wheat KWU25 last traded 1-3/4 cents lower at $5.17 a bushel. September 2025 through July 2026 all posted contract lows.

• Minneapolis September spring wheat MWEU25 hit a contract low of $5.69-1/4 a bushel on Monday but settled 3/4 cents higher at $5.73 a bushel.
