About This Agent

Data on This Page

RWA broken out by risk type (credit, market, operational, CVA), calculation approach (IRB Advanced, Standardised, FRTB SA/IMA, SMA) and legal entity, with a per-line current/pending-review status. Stat tiles roll up group RWA (£151.7B), credit RWA (£98.4B), combined market and CVA RWA (£30.5B), and outstanding model overrides.

What This Agent Does

Recalculates risk-weighted assets nightly (and on-demand) across every risk type and entity, applying the correct regulatory approach per portfolio, flags rating migrations and model overrides needing sign-off, and feeds the resulting RWA figures directly into the Capital Adequacy agent's ratio calculations.

Worked Examples

  • Credit Risk IRB Advanced RWA rose to £74.2B after a ratings migration moved £1.1B of corporate exposure from investment to sub-investment grade.
  • FRTB IMA market RWA of £6.5B is flagged pending review after last week's P&L attribution test showed a red-zone breach in the rates desk.
  • CVA RWA of £8.9B reflects a new counterparty netting set added for a cleared derivatives client onboarded this month.
