Banks can use this approach only subject to approval from their local regulators. Under F-IRB banks are required to use regulator's prescribed LGD (Loss Given Default) and other parameters required for calculating the RWA (Risk-Weighted Asset) for non-retail portfolios. For retail exposures banks are required to use their own estimates of the ...
Banks can use this approach only subject to approval from their local regulators. Under A-IRB banks are supposed to use their own quantitative models to estimate PD ( probability of default ), EAD ( exposure at default ), LGD ( loss given default ) and other parameters required for calculating the RWA ( risk-weighted asset ).
Banks are allowed to use multiple ratings systems for different exposures, but the methodology of assigning an exposure to a particular rating system must be logical and documented; banks are not allowed to use a particular rating system to minimize regulatory capital requirements. A rating system must be designed based on two dimensions
To be well-capitalized under federal bank regulatory agency definitions, a bank holding company must have a Tier 1 capital ratio of at least 6%, a combined Tier 1 and Tier 2 capital ratio of at least 10%, and a leverage ratio of at least 5%, and not be subject to a directive, order, or written agreement to meet and maintain specific capital levels.
The key variables for (credit) risk assessment are the probability of default (PD), the loss given default (LGD) and the exposure at default (EAD).The credit conversion factor calculates the amount of a free credit line and other off-balance-sheet transactions (with the exception of derivatives) to an EAD amount [2] and is an integral part in the European banking regulation since the Basel II ...
In late 2008 and early 2009, prominent scholars such as Alan Blinder, John Coffee, Niall Ferguson, and Joseph Stiglitz explained (1) the old net capital rule limited investment bank leverage (defined as the ratio of debt to equity) to 12 (or 15) to 1 and (2) following the 2004 rule change, which relaxed or eliminated this restriction ...
The term standardized approach (or standardised approach) refers to a set of credit risk measurement techniques proposed under Basel II, which sets capital adequacy rules for banking institutions. Under this approach the banks are required to use ratings from external credit rating agencies to quantify required capital for credit risk. In many ...
The leverage ratio, measured as debt divided by equity, for investment bank Goldman Sachs from 2003–2012. The lower the ratio, the greater the ability of the firm to withstand losses. While leverage allows a borrower to acquire assets and multiply gains in good times, it also leads to multiple losses in bad times. During a market downturn ...
