Market risk: standardised approach for specific risk in the correlation trading portfolio (MKR SA CTP): a total must equal the sum of its parts (OF20.00.01.01, C14.01.01.01, OF19.00.01.01, Bank of England check v7383_m)

The rule in plain words

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. 02Add up the parts in your return and compare the result with the total.
3. 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
4. 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
5. 05It runs only when your filing indicators mark C14.01.01, OF19.00.01 and OF20.00.01 as reported.
6. 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.

The cells it reads

Which returns it applies to

Line4 Check runs it on the own funds (PRA001) return on Bank of England banking taxonomy 4.1.1. The Bank of England applies it to own funds (PRA001) returns, as a warning.

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:

v7383_m: [C14.01.01.01] sum({C14.01.01.01, c0470, (rNNN, sNNN)}) = {OF19.00.01.01, r0010, c0060} + {OF20.00.01.01, r0010, c0060} + {OF20.00.01.01, r0110, c0060} + {OF20.00.01.01, r0120, c0060}
