The rule in plain words
In each of 6 rows (listed below) of Market risk: standardised approach for specific risk in the correlation trading portfolio (MKR SA CTP) (OF20.00.01.01): "Long" (column 0050) must equal the sum of 11 cells (listed below).
What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 02Add up the parts in your return and compare the result with the total.
- 03If they differ, a part is missing, a value sits in the wrong cell, or the total is out of date.
- 04The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 05It runs only when your filing indicators mark OF20.00.01 as reported.
- 06This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
