MT526 Usage Rules

This message is normally sent by only one of the parties to a securities loan. Confirmation of any action requested would normally be made using an MT 516 Securities Loan Confirmation, subject to bilateral agreement. The exception to this general rule is the acknowledgement to the MT 526 requesting that securities be held until further notice where the MT 526 may be used.
