Only 8% of the rice produced worldwide is traded on international markets, making tradable surplus relatively scarce. This makes rice prices particularly susceptible to events which affect either production (such as drought, flooding, storms) or rice available on the international market (due to domestic policies restricting the trade of rice for food security reasons). For example, in 2008, the world saw a rapid rise in rice prices following India’s decision not to allow the export of rice. As a staple crop, such price rises can have dramatic effects on countries that are dependent upon rice imports. In 2008, countries such as Senegal and Haiti faced civil unrest due to rising rice prices.
