The amount of 'Total collateral swaps' must be equal or higher to the amount 'of which intra-group activity' (LV49.00.00.01, Bank of England check boe_b0034)

A blocking check on the (LR6) Treatment of collateral swaps template (LV49.00.00.01), in the contingent leverage (LVR002) return.

Line4 Check runs it on the contingent leverage (LVR002) return, proven on test files, check by check: the same outcome on all eight test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

The amount of 'Total collateral swaps' must be equal or higher to the amount 'of which intra-group activity'

In each of "Market value of collateral lent (period end)" (column 0010) and "Market value of collateral borrowed (period end)" (column 0020) of (LR6) Treatment of collateral swaps (LV49.00.00.01): "Total collateral swaps" (row 0010) must not be less than "of which intra-group activity" (row 0040).

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. 03It runs only when your filing indicators mark LV49.00.00 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
