Counterparty credit risk: CCR exposures treated with standardised approaches: SA-CCR or simplified SA-CCR (CCR 3): a value must not be less than another (C34.03.01.01, Bank of England check v09817_m)

A warning on the counterparty credit risk: CCR exposures treated with standardised approaches: SA-CCR or simplified SA-CCR (CCR 3) template (C34.03.01.01), in the own funds (PRA001) return.

Line4 Check runs it on the own funds (PRA001) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In each of "Number of transactions" (column 0030), "Notional amounts" (column 0040), "Current market value (CMV), positive" (column 0050) and "Add-on" (column 0070) of Counterparty credit risk: CCR exposures treated with standardised approaches: SA-CCR or simplified SA-CCR (CCR 3) (C34.03.01.01): "Interest rate risk" (row 0050) must not be less than the sum of "Of which: largest currency" (row 0070), "Of which: 2nd largest currency" (row 0080), "Of which: 3rd largest currency" (row 0090), "Of which: 4th largest currency" (row 0100) and "Of which: 5th largest currency" (row 0110).

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 table below and find the cells the rule reads.
  2. 02Compare the values in your return. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C34.03.01 as reported.
  5. 05This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The Bank’s own words and formula

The plain words above spell out the Bank’s formula, with each cell named from its templates. In the Bank of England’s list of validations, word for word:

v09817_m: [C34.03.01.01 (c0030;0040;0050;0070, All sheets)] {r0050} >= {r0070} + {r0080} + {r0090} + {r0100} + {r0110}

The Bank of England's formula. Cells are written as {t: table, r: row, c: column}.

{t: C34.03.01.01, r: 0050} >= {t: C34.03.01.01, r: 0070} + {t: C34.03.01.01, r: 0080} + {t: C34.03.01.01, r: 0090} + {t: C34.03.01.01, r: 0100} + {t: C34.03.01.01, r: 0110}

Where it applies, in the Bank's words (its scope):

Checks like this one, run at the point of submission, are the first step to real-time supervision. Line4 builds SupTech software for financial regulators that runs checks like these as each return arrives.
