This paper aims to replicate the semiparametric Value-At-Risk model by Dias (2014) and to test its legitimacy. The study confirms the superiority of semiparametric estimation over classical methods such as mixture normal and Student-t approximations in estimating tail distribution of portfolios,...

Central banks around the world have substantial domestic and foreign financial assets and liabilities on their balance sheets reflecting their role as monetary authorities. This paper explores the long-term trends in risk and return in central banking using the central bank of Denmark, Danmarks...

FX rates are increasingly volatile in recent macroeconomic and geopolitical times of uncertainty. FX risk if not dealt with properly can pose existential threads to companies. Especially fast-growing companies, that have previously not hedged FX risks due to insignificance, need to build up a...

This paper examines whether the pairwise comovement between stocks quoted on the Stockholm stock exchange can be correctly quantified by the Gaussian copula, i.e., by linear correlation. Two different methods are used to test whether the dependence on the Swedish stock market can be modeled by...

When dealing with market risk under the Basel II Accord, variation pays in the form of lower capital requirements and higher profits. Typically, GARCH type models are chosen to forecast Value-at-Risk (VaR) using a single risk model. In this paper we illustrate two useful variations to the...

Asset managers are often given the task of restricting their activity by keeping both the value at risk (VaR) and the tracking error volatility (TEV) under control. However, these constraints may be impossible to satisfy simultaneously because VaR is independent of the benchmark portfolio. The...

Recognizing that many banks suffered trading losses that notably exceeded their minimum capital requirements during the recent crisis, the Basel Committee on Banking Supervision (2011) revised its regulatory framework for trading portfolios. In this paper, we compare: (1) the relative...

This paper provides explicit expression for the lower bound and the upper bound of the overall VaR of a portfolio of business units when the joint risks factors of each business unit follows a mixture of multivariate elliptic distributions with dynamic conditional correlation matrix. We use...

Sequential maximum likelihood and GMM estimators of distributional parameters obtained from the standardised innovations of multivariate conditionally heteroskedastic dynamic regression models evaluated at Gaussian PML estimators preserve the consistency of mean and variance parameters while...
