Tight U.S. cattle inventories—the smallest since the 1950s, with the July 2026 beef cow herd at roughly 28.5 million head and a record-low 32.5 million calf crop—remain the dominant driver keeping ground beef prices near all-time highs of $6.92 per pound in August 2026. Strong consumer demand, elevated feed costs from drought, and slow heifer retention have limited supply growth, while USDA lowered its 2026 beef production forecast and projects prices up 9.4% for the year. The September expansion of the tariff-rate quota for 300,000 metric tons of lean trimmings produced only marginal retail relief (down ~2% in surveys), as imports failed to offset domestic constraints. Traders are monitoring feedlot placements, fall slaughter data, and any further policy shifts for signals on whether prices sustain or ease into year-end.
