An undesirable trading situation (UTS) arises when there is a threat to orderly trading on the wholesale market or settlement that cannot otherwise be resolved satisfactorily under the rules. The Commission is able to investigate any potential UTS and can take actions, as it considers appropriate, including suspending rule requirements and imposing new requirements on participants.

The Undesirable Trading Situation (UTS): Guidelines for Participants documents the framework within which the Board intends to manage a UTS, and sets out the process and contact details for parties to use in order to have the Board promptly consider any claim that a UTS exists or is developing.
