Procyclicality and Value at Risk

نویسنده

چکیده

simply stated, a vaR model is a model of the distribution of future profits and losses of a bank’s trading portfolio. vaR models combine information on a bank’s trading positions across various products with statistical estimations of the probability distribution of the underlying market factors and their relation to each other. the final output of a vaR model is a vaR estimate, which is defined as the maximum amount of money that a bank would expect to lose over a defined period and with a defined confidence level. For example, if a bank has a 99 per cent, 1-day vaR of $100 million, this means that 99 times out of 100, the bank’s trading portfolio should not lose more than $100 million the next day. put another way, one day out of 100, the bank should expect to lose $100 million or more.

Procyclicality has emerged as a potential drawback to adoption of risk-sensitive bank capital requirements.

Procyclicality may result from systematic risk emanating...

Forward-looking estimation of default probabilities with Italian data

The solution adopted in Basel II to deal with procyclicality of capital requirements implies a reduction in risk-sensitivity that contradicts the original spirit of the document. To preserve risksensitivity and to dampen procyclicality at the same time, Pederzoli and Torricelli (2005) set up a model based on a business cycle forecast in the estimation of the default probability and provide an a...
