(LR9) Treatment of internalised trades: a value must not be less than another (LV52.00.00.01, Bank of England check boe_b0067)

A blocking check on the (LR9) Treatment of internalised trades template (LV52.00.00.01), 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.

The rule in plain words

'Cash prime brokerage - Internalised (period end)' amount must be higher than or equal to the amount 'of which level 1 HQLA - Internalised (period end)'

In column "Internalised (period end)" (0020) of (LR9) Treatment of internalised trades (LV52.00.00.01): "Cash prime brokerage" (row 0010) must not be less than "of which level 1 HQLA" (row 0030).

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 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 LV52.00.00 as reported.
  4. 04This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
