The waterfall

Both insolvency and resolution allocate losses class by class: no class bears loss until the classes below it are exhausted, and creditors within a class rank equally. In resolution the sequence is prescribed by Article 48 BRRD — Common Equity Tier 1 is written down first, then Additional Tier 1, then Tier 2, then subordinated debt, then senior non-preferred, and only then ordinary senior liabilities, with covered deposits and secured claims such as covered bonds excluded altogether.

Why it anchors everything

The hierarchy is the reference for the no-creditor-worse-off safeguard, the reason MREL carries subordination requirements, and the pricing logic behind every seniority class in this database. Its partial harmonisation — Directive (EU) 2017/2399 created the senior non-preferred layer, but depositor preference details still differ by member state — remains one of the open issues in the CMDI reform debate.
