US Cash Grains-Corn basis firms at processing and river sites

CHICAGO, Nov 17 (Reuters) - Basis bids for corn firmed across the U.S. Midwest on Monday, improving at processing sites and ethanol plants as well as river terminals, spot checks showed.

The basis for corn improved by a nickel at Decatur, Illinois, a key processing site, and also strengthened at processors in Blair, Nebraska, and Cedar Rapids, Iowa.

The U.S. harvest of corn and soybeans is nearly over brokers have said.

A drop in Chicago Board of Trade corn futures CZ25 on Friday may have discouraged farmer grain sales. CBOT December corn CZ25 fell more than 2% on Friday after the U.S. Department of Agriculture trimmed its estimate of the U.S. 2025 corn yield less than most analysts had expected.

CBOT corn futures rose on Monday but stayed below last week's highs.

CBOT soybean futures, however, surged on Monday on optimism about export demand for U.S. supplies of the oilseed. GRA/

Also, the National Oilseed Processors Association said that its members crushed a record-high 227.6 million bushels of soybeans in October, up 15.1% from September and up 13.9% from a year earlier. The figure topped a range of trade expectations.
