Part 4: Central counterparties: a value must not be less than another (SR807.04.07.01, Bank of England check boe_b1070_m)

A warning on the part 4: Central counterparties template (SR807.04.07.01), in the use of financial market infrastructures (RFB007) return.

Line4 Check runs it on the use of financial market infrastructures (RFB007) return, proven on test files, check by check: the same outcome on all seven test files of that return.

Check your file for this ruleWhat to do if it fails

The rule in plain words

In Part 4: Central counterparties (SR807.04.07.01): "Peak initial margin posted (to CCP or clearing member as relevant)" (column 050) must not be less than "Average initial margin posted (to CCP or clearing member as relevant)" (column 040).

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 SR807.04.07 as reported.
  4. 04This is a warning. It does not stop the return on its own, but your supervisor may ask you to explain it.
