Argentine FOB Up River soybean oil cash premiums ended August at unusually high levels, above Brazilian FOB Paranaguá, which normally trades at a premium to Argentina. Slow soybean sales by Argentine farmers, with high export taxes of 33% on soybeans and products, have squeezed local supplies and crushing operations.
Tight Argentine soy oil availability lifts export premiums and supports global soybean oil prices, while farmers' preference for corn exports, which carry a 12% tax, shifts flows.
After 842 past bullish policy events, Soybean Oil moved a median +0.2% over 5 sessions (52% higher; middle half -1.6% to +2.1%), and -0.5% over 20.
