uranium bubble of 2007
The uranium bubble of 2007 was a period of nearly exponential growth in the price of natural uranium, starting in 2005 and peaking at roughly $300/kg (or ~$135/lb) in mid-2007. This coincided with significant rises of stock price of uranium mining and exploration companies. After mid-2007, the price began to fall again and at end 2010 was relatively stable at around $100/kg.
==Causes==
The upward trend for the prices of uranium was already apparent since 2003. This prompted increases in mining activity. A possible direct cause for the bubble is the flooding of the Cigar Lake Mine, Saskatchewan, which has the largest undeveloped high-grade uranium ore deposits in the world. This created uncertainty about short-term future of the uranium supply.〔 Other factors are speculation triggered by growing expectations around India and China's nuclear programs, and a reduction in available weapons-grade uranium.〔http://www.cfr.org/energy/global-uranium-supply-demand/p14705〕
