The Caspian basin also contains a sea of oil

With prices rising continually, and companies making substantial profits in tandem, oil seems one of the most sensible commodities to invest in. However, this overlooks underlying concerns about the security of the oil supply in Iraq and the political stability of other big producers in the Persian Gulf. So investors will consider alternative sources of oil.

..The question is: is it worth investing in Caspian Sea oil, and why? Politically, the region has become much more unstable in the past two years. The overthrow of President Akayev in Kyrgyzstan was the first in this particular area. And there was a concern about a domino effect on other governments in the region, especially on big oil producers such as Turkmenistan and Kazakhstan.
