Abstract

Most financial institutions use credit value-at-risk (VaR) produced by Monte-Carlo simulation or analytical approximation. While Monte-Carlo simulation needs large computational resources, and many approximation formulas have been proposed. We discuss the granularity adjustment approximation, and apply it to calculating incremental VaR. Through numerical experiments we show that we can obtain better approximation results by the granularity adjustment formula concerning incremental VaR.
