Additional liquidity monitoring metrics: every EBA validation rule in plain words (ALMM)

Additional liquidity monitoring metrics (ALMM) show a supervisor when a bank’s cash flows fall due and where its funding comes from. The core is a maturity ladder (template C 66.01). Most institutions report it every month, and EBA’s validation rules check that the ladder adds up.

EBA's 4.2 package has 140 validation rules for it. Line4 Check runs 134 of them (11,864 written-out checks): 0 can block a filing and 134 are warnings. EBA has switched 6 off.

The rules, by template

Each rule in plain words, its code in brackets. Open one for what to do if your filing fails it. A rule that reads more than one template is listed under the first. Rules are warnings unless marked blocking.
