Large Exposure regulations require banks to consolidate all their credit exposures to groups of related entities, and report/control these against limits expressed as a percentage of their Tier 1 Capital. ACR would be an ideal solution to calculate and monitor Large Exposures:
It already caters for counterparty risk, lending risk, and issuer measures
It features configurable customer hierarchies
It features an auto-limit framework that would cater for limits expressed as a percentage of the bank's capital
A base Large Exposures solution would require the following enhancements:
A new 'Overall' measure that consolidates all components of a Large Exposure
A parallel set of LE compliant measures that mirror internal measures for:
OTC Derivatives (SA-CCR)
Securities Finance (SFT EAD)
Lending /Banking Book
Lending Contingent
Issuer Risk
Issuer Contingent (exposure to issuers of collateral)
Dedicated Large Exposure customer hierarchy
Auto-limits expressed as a bank of the bank's capital
