The Creditflux league tables are the most reliable and closely watched measure of dealer and manager activity in the CSO and index tranche markets. Despite the private nature of these markets, we estimate that the league tables cover 80% of the bespoke CSO business and 85% of index tranche volumes.
Creditflux has published CSO league tables for a number of years, allowing subscribers to follow changes in dealer market share.
We publish regular league and volume tables based on CDOs included in Creditflux Data+. There are a number of sources for the information, including rating agency press releases and other announcements. In addition, we ask counterparties and managers to submit details of recently traded deals at the end of each quarter. At the end of the year, the data for the four quarters is added to produce full year league and volume tables.
The basic methodology for the league tables is to add together the volume of tranched portofolio protection bought and sold by each counterparty and then to apply a risk weighting to those totals. Volumes included unfunded trades (including those collateralised through a CSA ) and funded trades isssued in the form of a credit-linked note.
