US soyoil basis in the Gulf hit a record premium to Argentina and Brazil on June 1, with the US-Argentina spread at 31.7 cents per lb. The spread narrowed later in the week amid a CME soyoil futures sell-off.

A wide US export premium reflects tight US supply relative to mandates, but the recent narrowing and futures sell-off signal some easing in the price pressure on US soyoil.
