Dearth of liquid products and historic data threatens banks with capital hit under new market risk rules
Measure aims to provide better gauge of VAR violations
In this paper, the authors present a new backtest for the unconditional coverage property of expected shortfall.
This paper analyzes the impact of different estimation window strategies, including structural breaks and forecast combinations, on forecasting common risk measures such as VaR and ES.
Outsize loss events modellable through extension of approach to measuring moderate losses, says research
In this paper, the author presents a simple probabilistic model for aggregating very large losses into a loss collection.
VAR and ES are ineffective to deter rogue trading
Quants show popular risk measures fail to limit risk-seeking behaviour among traders
Regulators should try to combat rogue trading by measuring traders’ risk-taking differently, say quants
Negative rates prompted switch in the CCP’s margin calculation model for interest rate swaps
This paper provides a detailed analysis of the relationship between approximate VaR (ES) and exact VaR (ES) by finding a linear regression model in which the response variable is the approximate VaR (ES) and the explanatory variable is the exact VaR (ES)…
This paper compares mVaR and mES estimators with VaR and ES under normal and fat tailed t-distributions.
This paper focuses on the parametric estimators of risk measures and uses Hampel’s infinitesimal approach to derive the robustness properties.
