Definition: Structured bond
External debt - IMF
Structured bonds have characteristics that are designed to attract a certain type of investor and/or take advantage of particular market circumstances.
However, structuring securities to appeal to a particular type of investor risks the possibility of a loss of liquidity if the market moves in such a way as to make the structured features of the issue no longer attractive.
Typically the structured features are achieved through the use of derivatives—for instance, a credit-linked note is a bond with an embedded credit derivative.
