This study addresses estimation of VaR statistics for Brady bond portfolios using several versions of the GARCH(1, 1) framework, which explicitly models time-varying volatility. In a hybrid approach univariate ARCH models are used jointly with rolling correlation matrices. Variance-covariance and GARCH methodologies all produce reasonably accurate one-day VaR estimates. A GARCH(1, 1) model with stochastic shocks yields the most accurate VaR measures regardless of horizon, but variance-covariance, and two other GARCH variant models appear to underestimate portfolio risk, especially over longer horizons. %U https://jfi.pm-research.com/content/iijfixinc/10/3/7.full.pdf
