Emerging             market bonds are the bonds offered by less developed countries. The             government normally issues them. These exclude borrowings from             government, supranational organizations such as the International             Monetary Fund or private sources. These include loans that are             collateralized and are offered in the financial markets.             Among all emerging market bonds, investors prefer to invest in             mutual funds. 
These             bonds tend to have a lower credit rating when compared to any other             sovereign debt because of the increased economic and political             risks.
Countries             normally do not opt for emerging market bonds unless the borrowing             is wide enough to justify the costs involved. Hence, most of the             developing and under developed countries are behaving indifferently             to emerging market debt instruments.
