Argentina suspended agro-export taxes on grains, oilseeds and by-products to zero until October 31 to speed export sales and raise US dollars. The tax holiday was reinstated two days later after a US currency swap deal, following earlier July cuts to export duties.
Export tax swings drive farmer selling and exporter bookings, so a temporary zero-tax window pulls forward Argentine supply, while the reinstatement shifts flows back and adds volatility to soymeal, soyoil and corn export pricing.
