One of the underlying reasons OTC trades aren’t ready to be cleared, is simply the proportion which can be electronically confirmed. The chart below extracted from the recent (May 2012) ISDA survey shows some automation opportunities for the OTC market. I’ve highlighted the bigger gaps, the right hand column is part of the story too, many trades aren’t even capable of being electronically confirmed, in EQD more than 50% across the board are in this category.

The ISDA survey for 2012 (and earlier years) is here.
