Open derivatives: a conditional check (IR.08.01, Bank of England rule IR_bv0562_02)

A blocking check on the open derivatives template (IR.08.01), in the quarterly group (QRG) and annual group (ARG) returns.

The rule in plain words

The items "Premium paid to date" and "Premium received to date" in Open Derivatives (IR.08.01) are not applicable for futures and forwards (CIC ##A# and ##E#)

The headline gives only the template and the kind of check, because the rule is too long to say in a headline. The plain words above say all of it.

What to do if your return fails it

  1. 01Open the tables below and find the cells the rule reads.
  2. 02The check applies only when its first part holds in your return. When it does, the second part must hold too: fix the second part, or correct the first.
  3. 03It runs only when your filing indicators mark IR.08.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
