Cattle Market Guys - Tuesday Check In 6-9-2026

New World Screwworm has been confirmed in multiple Texas counties, and it's moving fast — at least four cases across Zavala and La Salle counties in a matter of days, triggering a livestock quarantine, a disaster declaration, and immediate ripple effects across both the cash and futures markets. This is the most significant livestock biosecurity threat to hit the U.S. in decades, and ranchers need to understand what it means right now. In this Tuesday Market Update for June 9, 2026, Brock and Jim break down the week's cattle market numbers, including strong early-week prices in the 500–549 lb. steer class at $475.80/cwt and a notable gap opening up between cash and futures markets. They walk through model forecasts for the next one to four weeks and explain why the heavier weight classes are flashing a timing signal for producers with flexibility. The episode digs deep into the screwworm outbreak — how it entered the U.S., how quickly it's spreading geographically, and why Jim's firsthand experience checking cattle in Presidio County in 1976 still carries hard lessons for ranchers in affected areas today. Brock and Jim also cover the trade disruptions flowing from the outbreak, including border restrictions with both Mexico and Canada, new tariff uncertainty across 60 countries, and what Brazil's clean FMD status signals about competitive dynamics in global protein markets.
