The 43-day government shutdown delayed release of USDA crop reports, yet recent estimates still project record-high yields for this year's corn and soybean harvest. Planting, growing, and harvest conditions in central Illinois were characterized by a wet spring followed by an extremely dry late summer and fall. Corn prices improved during harvest, while an increase in soybean prices have recently experienced a decline, yet still 9% higher than a year ago. The FOMC's third straight lowering of the Fed Funds rate by 0.25% in as many sessions has produced a more conventional yield curve, especially in the 3 year to 30 year portion of the curve. The 30-year fixed-rate mortgage (FRM) averaged 6.22% as of 12/11/25, down from the 6.6% average of a year ago; the 15-year FRM average is 5.54%, down from the 5.84% average of this time last year.
