Structured products have established a foothold in the US retail markets, but some analysts say even leading issuers such as DWS parent Deutsche Bank, UBS, Barclays and Citigroup may struggle to maintain momentum.

Indeed, the fledgling industry has gained traction in recent years, growing from $64bn (£32bn, €40bn) to $114bn between 2006 and 2007, according to estimates from the Structured Products Association. But tax issues, distribution challenges and investor mindset will make it difficult for banks offering the products to keep that growth going.
