Structured deposits are bank deposits where the return is linked to the performance of an underlying reference, such as an equity index, a basket of shares, or an interest rate. Their main attraction is the possibility of achieving a higher return than a conventional fixed or variable rate deposit, depending on how the underlying reference performs and on the product’s payoff formula. This return is not guaranteed at a high level, because it is conditional on outcomes such as an index reaching a level, staying within a range, or not breaching a barrier. Many structured deposits include some form of capital protection at maturity, but investors still face risks such as opportunity cost, limited liquidity, and issuer credit risk. They are not inherently tax free, as tax treatment depends on the jurisdiction and the investor’s circumstances. They also do not automatically reduce income tax liability. CISI exam framing usually tests that the benefit is enhanced return potential in exchange for complexity and conditionality, not guaranteed performance or tax advantages.
