In light of IBOR cessation, IHS Markit has published the updated trading conventions for Standardized TRS on each of the three currencies of iBoxx indices. This transition is for new trades only and would not impact legacy trades. Counterparties will need to agree on the treatment of legacy trades bilaterally.
The trading conventions are outlined in the attached Standard iBoxx TRS - Trading Convention Guide document, which is also available for download from the iBoxx TRS documentation page.
