Fourteen EU banks face sanctions for poor market risk models

European Union authorities will take action to address shortcomings with the market risk models of 14 lenders following the results of the latest supervisory benchmarking exercise (SVB) by the bloc’s banking watchdog.
Penalties will range from supervisory reviews of value-at-risk and incremental risk charge models to capital add-ons.
Four banks were deemed ‘high priority’ for intervention based on, among other reasons, their outlier status following the benchmarking analysis, history of

Measurement of operational risk regulatory capital in the banking sector: developed countries versus emerging markets


Journal of Operational Risk
Abstract
This paper addresses operational risk as a fundamental risk type faced by banks in emerging and developed economies. We explore several models to specify the marginal and joint distributions of the types of operational losses that reflect loss frequencies and severity distribution(s), using international data published by a group of banks from developed and emerging economies. Our results reveal that a uniform approach to model operational risk in both types of economy may lead to the overestimation or underestimation of capital losses in banks. This could result in opportunity costs of holding excessive capital to mitigate operational losses, or in extra costs resulting from an underestimation of the capital required. ....

Bias-corrected estimators for the Vasicek model: an application in risk measure estimation


Need to know
Our Monte Carlo simulation results indicate that the widely-used least squares estimations of the Vasicek model suffer significant small-sample biases even if the sample length reaches as long as 30 years.
Bias-corrected estimators could substantially reduce the small sample biases of the least squares estimations, and further project much more accurate value-at-risk and potential future exposure estimates.
Empirical applications to a variety of time series are in general in line with the Monte Carlo simulation results.
Abstract
We evaluate the usefulness of bias-correction methods in enhancing the Vasicek model for market risk and counterparty risk management practices. The naive bias-corrected estimator, the Tang and Chen bias-corrected estimator and the Bao ....
