Structured notes can offer attractive returns, but they come with notable risks that investors should carefully consider. One of the primary concerns is liquidity risk, as these products often lack a secondary market, making it difficult to sell before maturity without potentially accepting a steep discount. 

Market risk is also a factor, since structured notes are tied to the performance of underlying assets that may be volatile, especially when linked to speculative markets. Even if a note includes downside protection, extreme fluctuations can still lead to losses. 

Default risk is another major issue, as the investor’s return ultimately depends on the solvency of the issuing institution. In the event of a bankruptcy—such as Lehman Brothers’ collapse—investors may lose their entire principal regardless of market performance.

Finsum: However, when structured thoughtfully, these notes can offer enhanced yields, downside buffers, or tailored exposure to specific markets not easily accessed through traditional investments.
