The rule in plain words
In each of 12 rows (listed below) of Market risk: standardised approach for specific risk in the correlation trading portfolio (MKR SA CTP) (OF20.00.01.01): the size of "(-) Short" (column 0040) (ignoring its sign) must not be more than "Short" (column 0020).
What to do if your return fails it
- 01Open the table below and find the cells the rule reads.
- 02Compare the values in your return. If the first is bigger than it may be, one of them is wrong: check both before you change either.
- 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
- 04It runs only when your filing indicators mark OF20.00.01 as reported.
- 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
