In recent years, low interest rate environments have made it challenging for structured product issuers to create products that meet investors’ needs. Decrement indices, which can serve as the basis for these products, have gained traction with issuers by incorporating an overlay that intends to represent the deduction of a predefined fee. Catering to a wide range of needs, S&P Dow Jones Indices offers decrement indices based on a variety of underlying indices including the iconic S&P 500®, innovative measures of ESG, climate and net zero-focused companies, and thematic indices covering emerging technologies, societal trends and more.
