ISDA has published the ISDA Standing Settlement Instructions (SSI) suggested operational practices (SOP), which outlines a set of guidelines for the communication, management and usage of SSIs.

The document aims at increasing standardization and efficiency in performing payments for over-the-counter (OTC) derivatives and it is an update to the Best Practice Statement that was published by ISDA on August 11, 2010.

SOPs for the exchange of SSIs for the purposes of collateral are available in section 1.7 of the Suggested Operational Practices for the OTC Derivatives Collateral Process.
