Content of the submission and solvency capital requirement - market risk: a conditional check (IR.01.01, IR.26.01, Bank of England rule IR_bv1762)

A warning on the content of the submission (IR.01.01) and solvency capital requirement - market risk (IR.26.01) templates, in the annual solo (ARS) return.

The rule in plain words

If the net capital charge for spread risk on credit derivatives, after adjustment for the loss absorbing capacity of technical provisions is reported in Solvency Capital Requirement - Market risk (IR.26.01) then the absolute value of assets sensitive to the downward/upward shock in respect to the spread risk on credit derivatives also has to be reported

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.01.01 and IR.26.01 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
