1 min readWarningEBA reporting framework 4.2Updated 10 November 2026

Initial stock cannot be negative (C 66.01.b, EBA rule v5905_s)

A warning in the additional liquidity monitoring metrics return (ALMM), on template C 66.01.b, maturity ladder, total, initial stock.

The rule in plain words

Initial stock cannot be negative.

The value is on the total currencies sheet (0010) of C 66.01.b.

EBA checks it for 38 rows, from coins and bank notes (0730) to assets reported in 3.6 that are non-HQLA central bank eligible (1241). That makes 38 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.

Level 2B corporate bonds (CQ1-3), Total currencies >= 0

What to do if your filing fails it

  1. 01Open the template below and find the cells the rule reads.
  2. 02Look for a value with the wrong sign in these cells, such as an amount entered as a negative number.
  3. 03EBA compares the values exactly here: there is no rounding tolerance.
  4. 04It runs only when your filing indicators mark C 66.01 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.

What the rule then expects

Level 2B corporate bonds (CQ1-3) must then be at least 0.

0Passes
-100Fails

A file that reports 0 passes. One that reports -100 fails, by 100.

The numbers are illustrative.

EBA's formula, as written out for the first of its checks. Cells are written as {template, row, column, sheet}.

{C_66.01.b,r0890,c0010,s0010} >= 0

The next five:

{C_66.01.b,r0990,c0010,s0010} >= 0{C_66.01.b,r0940,c0010,s0010} >= 0{C_66.01.b,r0790,c0010,s0010} >= 0{C_66.01.b,r0900,c0010,s0010} >= 0{C_66.01.b,r0830,c0010,s0010} >= 0

And 32 more, the same formula for the other cells it covers.
