BIS Risk-Based Capital Requirements 
 All private-sector loans (uncollateralized) are subjected to an 8 percent capital reserve requirement, irrespective of the size of the loan, its maturity, and the credit quality of the borrowing counterparty.
Disadvantages of BIS Regulatory Model
1. Does not capture credit-quality differences among private-sector borrowers
2. Ignores the potential for credit risk reduction via loan diversification
Model from Insurance (Credit Risk+)
 - Only two states of the world are considered- default and no default.
 - Spread changes (both due to market movement and rating upgrades/downgrades) are considered part of market risk.
 - Default probability is modeled as a continuous variable.
