The cotton leading market
The physical market (*the quantity of cotton is here expressed in millions of tons.)
We have to analyze the various countries or actors involved in such a market. The China is the biggest importer of cotton in the world, followed closely by Bangladesh and Turkey. In 2005/2006, the country imported about 4200 (*) before knowing a decrease of the importation due to the financial crisis. Indeed, Chinese textile workers had to reduce their demand due to the fact that they had more difficulties to sell their clothes or made of cotton products abroad. However, in 2009, worldwide cotton demand grew up from various countries that made the prices going up. The cotton imports were from 6582 to 7329 between 2009 and 2010.
USA is the biggest exporter in the world. However, its exports decreased beyond the years (from 3821 to 2395 between 2005 and 2009). This is mainly due to the fact that the United States of America decided to turn to more profitable activity, giving up investments into some large cotton production branches. The second larger exporter in the world, India, is so close to become the first exporter in the world. Its exportation doubled in 5 years, from 751 in 2005 to 1437 in 2010. India is a perfect place to produce cotton, because of its large landscapes, its sunlight days, and moreover the abundance of rain at some particular periods. Others emerging countries such as Uzbekistan (which is the third exporter in the world with 871 of cotton exported in 2010) develop their cotton exports and make its home production take an essential role into their economic growth. Cotton is not only kind of easy to produce in large quantity (enabling thus large economy of scale) but faces a sustainable worldwide demand, which attracts investors as well as government subsidies in quantity. Cotton exports in 2010 represented 7329 (?).
