"Currencies closely correlated" must not be less than "Of which: reporting currency" (SC22.00.01.01, Bank of England check boe_b0099_ss)

A blocking check on the information on foreign exchange risk for SDDTs (MKR SA FX SDDT) template (SC22.00.01.01), in the own funds for SDDTs (PRA116) return.

Line4 Check runs it on the own funds for SDDTs (PRA116) return, proven on test files, check by check: the same outcome on all three test files of that return.

The rule in plain words

In each of "Long" (column 0040) and "Short" (column 0050) of Information on foreign exchange risk for SDDTs (MKR SA FX SDDT) (SC22.00.01.01): "Currencies closely correlated" (row 0020) must not be less than "Of which: reporting currency" (row 0025).

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. 03The Bank of England allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark SC22.00.01 as reported.
  5. 05This is a blocking check. A return that fails it is normally rejected, so fix it before you submit.
