Loans to non-financial customers other than central banks where those loans are assigned a risk weight of 35% or less cannot be less than residential mortgages (C 80.00.w, EBA rule v10123_m)

A warning in the net stable funding ratio return (NSFR), on template C 80.00.w, nSFR - required stable funding (I), significant currencies.

The rule in plain words

Loans to non-financial customers other than central banks where those loans are assigned a risk weight of 35% or less cannot be less than residential mortgages.

EBA checks it for four columns: < 6 months, ≥ 6 months to < 1 year, ≥ 1 year and required stable funding. That makes four checks. A failure names the one that failed.

How the Line4 Check report words itShow

The first of its checks, word for word as the report shows it when it fails. The others read the same, with their own column, row or sheet.

< 6 months: loans to non-financial customers other than central banks where those loans are assigned a risk weight of 35% or less >= of which, residential mortgages

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Compare the values in your file. If the first is smaller than it may be, one of them is wrong: check both before you change either.
  3. 03EBA allows a small rounding difference, worked out from the decimals each value is reported with.
  4. 04It runs only when your filing indicators mark C 80.00 as reported.
  5. 05This is a warning. It does not stop the filing on its own, but your authority may ask you to explain it.

A worked example

The first of its checks, with simple numbers.

Illustrative values
loans to non-financial customers other than central banks where those loans are assigned a risk weight of 35% or less1,200
What the rule then expects

Residential mortgages can then be at most 1,200.

1,200Passes
1,300Fails

A file that reports 1,200 passes. One that reports 1,300 fails, by 100.

The numbers are illustrative, reported to the unit, so the rounding tolerance does not change the result.

Checks like this one, run at the point of submission, are the first step to real-time supervision.
