Mongolia's economy and foreign investment are heavily dependent on the Oyu Tolgoi copper and gold mine project. The project accounted for over 50% of foreign investment and significantly impacted GDP growth and budget revenues between 2009-2012. However, Mongolia now faces challenges in attracting further investment for exploration and mining. Mongolian mining companies' stock prices on global exchanges have declined 60-70%, and investors that operated at a loss are no longer interested in investing. Additionally, Mongolia faces high risks that unstable policies could increase interest rates on its $1.5 billion bond issued and planned $3.5 billion in future bonds.
