The Casillo family group, the leading supplier of durum wheat to Italian pasta manufacturers, has for several years systematically responded to calls for tenders from the Tunisian cereals office. This has enabled it to bag a swathe of the country's supply contracts since the start of the Ukraine war.
The halt in Russian and Ukrainian wheat exports has opened a window of opportunity for French grain producers in North and West Africa, who in recent weeks have been able to act as substitute suppliers at short notice.
With grain shipments in the Black Sea becoming impossible, large and small suppliers of both millers and state agencies are having to adapt to meet their requirements. At the same time, prices are exploding, which may be a double-edged sword.
