What the concept describes
Going-concern loss absorption refers to the ability of a bank to absorb losses while it remains a functioning, operating institution, without entering resolution or insolvency. The term captures one half of a matched pair used throughout the prudential and resolution frameworks: capital that works while the firm is a going concern, as against capacity that is only called upon once the firm has become a gone concern.
The primary source of going-concern loss absorption is regulatory own funds, and above all common equity tier 1. CET1 sits at the top of the capital stack and absorbs losses first and continuously: unrecognised losses erode retained earnings and reserves, reducing CET1 directly, without any need for a trigger event or supervisory action. Additional tier 1 instruments contribute a more conditional form of going-concern absorption, because they convert to equity or are written down when the CET1 ratio falls to a contractual trigger while the bank is still operating. Tier 2 instruments are generally regarded as gone-concern capital, since they principally absorb losses at the point of non-viability rather than during ordinary operation, although they still count towards own funds.
How it works in practice
Because CET1 absorbs losses on a continuous basis, it is the buffer that keeps a bank solvent through a stress. The framework layers requirements on top of the minimum: the Pillar 1 minimum, the Pillar 2 requirement set through supervision, and the combined buffer requirement. Breaching the buffers does not itself trigger failure; it restricts distributions through the maximum distributable amount, giving supervisors an early, going-concern lever before the point of non-viability is reached.
Going-concern absorption is therefore about preventing failure. If losses exhaust these resources and the bank can no longer meet its requirements or pay its debts, it crosses into the gone-concern space, where write-down and conversion powers and MREL-based recapitalisation take over.
Legal basis
There is no single article that defines going-concern loss absorption; it is a supervisory concept built on the own funds provisions of the CRR, Articles 25 to 88, which define common equity tier 1 (Articles 26 to 50), additional tier 1 (Articles 51 to 61) and tier 2 (Articles 62 to 71). The distinction between going-concern and gone-concern capital underlies the calibration of capital requirements in the CRD and of MREL in the BRRD.
Practical relevance for banks and investors
For banks, maximising reliable going-concern absorption means holding sufficient CET1 above the combined buffer so that ordinary losses never approach the point of non-viability. For investors, the going- versus gone-concern distinction determines when and how an instrument absorbs loss: CET1 and AT1 are exposed while the bank is still operating, whereas most of a bank's MREL stack is designed to work only in resolution. Judging where a given instrument sits in that spectrum is central to pricing its risk.
