外汇汇率的风险价值-Copula方法

On Value at Risk for foreign exchange rates - the copula approach

Piotr Jaworski

摘要:

本文的目的是确定风险价值(VaR)的投资组合,包括在新兴市场的外汇多头头寸。基于经验数据,我们限制自己的情况下,这些资产的对数收益率分布的尾部遵循幂律和相关copula C的下尾遵循幂律的程度1。我们将通过对波兰外汇市场欧元和瑞士法郎汇率的分析来说明这种方法的实用性。

英文摘要:

The aim of this paper is to determine the Value at Risk (VaR) of the portfolio consisting of long positions in foreign currencies on an emerging market. Basing on empirical data we restrict ourselves to the case when the tail parts of distributions of logarithmic returns of these assets follow the power laws and the lower tail of associated copula C follows the power law of degree 1. We will illustrate the practical usefulness of this approach by the analysis of the exchange rates of EUR and CHF at the Polish forex market.
