India has ordered a halt to exports of its main rice category, non-basmati white rice, in order to ensure adequate availability in the domestic market and contain price increases. The move, which follows an 11.5% increase in retail prices in the past 12 months, is expected to cut shipments from the world's biggest exporter of rice in half. The ban will impact around 10 million tonnes of India's 22 million tonnes of rice exports from last year, and is likely to have the greatest effect on African buyers.
