BoE working paper on releasable macroprudential capital buffer tail effects
Bank of England staff published a working paper assessing state-contingent tail effects of a releasable macroprudential capital buffer using an agent-based framework.
The research explores how releasable macroprudential buffers behave under stressed states, informing debate on CCyB design and release triggers. While not policy, it signals BoE thinking on buffer usability and may shape future FPC capital framework decisions.
Buffer usability and release mechanics directly affect required capital headroom and management buffer sizing.
Action Required
Monitor implications for countercyclical capital buffer calibration and integrate findings into capital planning stress narratives.
Signals potential direction of UK macroprudential capital policy relevant to capital strategy and ICAAP.
Track BoE research on releasable buffers as a leading indicator for CCyB framework evolution; consider sensitivity of capital plans to alternative buffer release regimes.
“Staff working papers set out research in progress by our staff, with the aim of encouraging comments and debate.”
