Large harvests in the Americas have eased global grain supply pressure and weighed on prices, but regional availability remains uneven. Black Sea infrastructure disruption has constrained Russian and Ukrainian grain movements, while European exporters and suppliers including Australia, Argentina, Canada and potentially the US compete to fill gaps; local crop and quality differences also affect markets.
Export disruption and uneven quality can tighten delivered supplies in particular regions even when global harvests are large, supporting local basis and premiums. Buyers may face higher sourcing and logistics costs despite weaker headline futures prices.
