Structured investment products refer to securities or deposits that consist of a fixed-income investment component and a risky derivatives component, or a stand-alone derivatives component only. The return on a structured investment is linked to the performance of selected underlying instruments, such as equities, equity indices, interest rates, mutual funds, currencies, commodities, credit risk or various combinations of the above. Structured products may have a capital-protected structure or they may be non-capital protected. Index-linked bonds are the most widely known type of structured investments. The first structured bond was issued in Finland in 1994.
