The rule in plain words

In General governments exposures by country of the counterparty and regulatory approach (Gov) (C33.00.01.01): every value in 24 rows (listed below) in 5 columns (listed below) must be zero or less.

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 bigger than it may be, one of them is wrong: check both before you change either.
  3. 03It runs only when your filing indicators mark C33.00.01 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
