Outstanding structured finance securities in the U.S. amount to more than $7.3 trillion and represent more than 30% of the total outstandings in the U.S. bond markets. Because of the market's size and the complexity of the instruments, structured finance professionals increasingly specialize in narrow sectors or sub-sectors within the structured finance universe. In doing so, they can lose touch with the "big picture" and relationships of different sectors to each other. However, keeping the big picture in view is necessary for making strategic decisions in the areas of risk management and asset allocation.
Viewed over a recent five-year time horizon, the credit card ABS sector was the most placid one on the structured finance landscape. In contrast, CMBS was the area to experience the greatest adverse change, with declining credit support levels, weakening collateral performance, and contrary to what one might expect – tightening spreads. The residential MBS sector displayed moderately negative trends. Other sectors, such as home equity ABS and auto ABS displayed mixed results.
