The tonnage of rice available for importing this year is falling drastically. The USDA estimated in March that rice for export was trending downward from the level of 30.85 mmt traded in 2006/7, down to perhaps 29.39 mmt to be traded this year. But this fantasy does not reflect the recent announcements by major rice exporting countries that are now limiting or banning exports. Of the 29 million metric tons of rice for trade or aid, only seven nations account for 27 mmt, and four of them have restricted exports, possibly adding up to a "loss to the markets" of 11.2 mmt. They are (their "normal" annual export tonnage is noted): Vietnam (5 mmt); India (3.5 mmt); China (1.3 mmt); Egypt (1.3 mmt). Additionally, Pakistan, which exported some 3 mmt in recent years, has none for export, and is beset by grain going to Afghanistan. Thailand, the world's leading grain exporter, is also restricting exports. Thus, 24.2 mmt, or over three-quarters of all the rice traded on the world markets, may not be there in coming months.

International: Thai quotes jumped $356, or more than 70 percent, from last month to $855 FOB, as exportable supplies remain tight and worldwide concerns over food security drive up export prices. Vietnam is not quoting prices due to an export ban, which leaves Thailand and the United States as virtually the only game in town.
USDA commentary, rice

"They became unruly demanding higher wages, saying their current wages don't even meet basic food needs," police sub-inspector Shafiqul Islam said.
The price of rice is a key issue in impoverished Bangladesh, where households are estimated to spend nearly 70 percent of their income on food.
"The 25 dollars basic minimum salary was fixed in 2006. But since then prices of rice and other food items have doubled or tripled," said Nazma Akhter, president of the United Garments Workers Union.
"With our poor salary, it is now impossible to buy three meals a day. Some of us are even going hungry some days," said Jamal Uddin, a sweater machine operator, who earns 30 dollars a month.

The data is a little old (1990), but until we find something more current/specific.
