Solvency capital requirement - operational risk: values must agree (IR.26.06, Bank of England rule IR_bv0678)

A blocking check on the solvency capital requirement - operational risk template (IR.26.06), in the annual solo (ARS) return.

The rule in plain words

The capital requirement after the cap reported in IR.26.06.01.01 -Solvency Capital Requirement - Operational risk should be equal to the lowest between the capital requirement before the cap and the cap (percentage of BSCR)

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.

This is a blocking check. A return that fails it is normally rejected, so fix it before you submit. It runs only when your filing indicators mark IR.26.06 as reported.
