| Abstract: | 台灣風險基礎資本額制度實施至今已將近七年，但風險係數卻從未調整，本研究主要針對股票指數與匯率之風險係數探討其是否有更新之必要，藉由1986年12月至2009年12月之資料，利用GARCH模型及EGARCH模型進行風險係數之估計，除了和風險基礎資本額制度相同，以風險值為考量外，另外加入條件尾端期望值，並比較其與風險值之差別。
實證結果發現，僅部分財務時間序列有顯著之槓桿效果，因此使用GARCH模型估計風險係數較為合適；所估計之風險係數，無論是股價指數或是匯率，其估計結果皆比現行標準高出許多。
In Taiwan, Risk-based capital (RBC) is set up in 2003. From 2003 until now, no matter how the economical environment has changed, the risk factors have remained all the same.This research mainly focuses on the risk factors of stock index and foreign exchange and wants to know if the risk factors need to be changed. The data this research encompasses is from December 1986 to December 2009.The risk factors are estimated by GARCH model and EGARCH model, utilizing not only the VaR but also the conditional tail expectation (CTE).
From the result, only a few financial time series have shown leverage effect, therefore it is indeed more appropriate to apply GARCH model in risk factors estimation. Moreover, the risk factors from the result of this research, whether it is stock index or foreign exchange rate, are significantly higher than the risk factors standard applicable in Taiwan at the present. |
