The United States halted live cattle imports from Mexico in 2024 after New World screwworm was detected there. A study found that the closure raised feeder cattle basis, meaning cash prices strengthened relative to futures, with effects varying by market distance from the border and the duration of the closure.
Mexico is an important source of U.S. feeder cattle, so suspended imports tightened available supply and supported cash feeder prices, particularly in affected markets. The uneven regional and time effects mean the price impact may differ across U.S. cattle-buying regions.
After 122 past bullish disease events, Feeder Cattle moved a median +0.4% over 5 sessions (60% higher; middle half -1.0% to +1.6%), and +2.0% over 20.
