隨著台灣公債市場近幾年的交易量越來越大,且債市將面臨空頭的走勢,公債避險的重要性就愈重要。雖然今年開始有公債期貨上市,但交易量小且流動性不足,無法有效滿足避險者需求。因此本研究以利率走勢與台灣較接近的美國市場作為避險工具,選擇CBOT的利率期貨(包括5年期、10年期、30年期)做避險工具,台灣的公債做避險標的(5年期、10年期、20年期)。透過交叉避險探討在不同避險模型(包括單純法、最小平方法、誤差修正模型、GARCH模型)以及不同避險期間(日、週、雙週、月)下是否有顯著的效果。資料期間為2000年至2004年3月,實證結果顯示:公債現貨與美國期貨間存在共整合關係,表示現貨與期貨之間有長期均衡關係,但現貨與期貨間並無明顯異質變異情況。各模型中以誤差修正模型避險效果最佳;最小平方法與GARCH 模型避險效果次之且相似;單純法避險效果最差,且多為負效果。避險比例除了日資料外多具有顯著性,且隨著避險期間越長效果越佳。另外,避險比例在樣本期間內的穩定性相當高,顯示台美的利率結構算滿穩定的。5年期公債以5年期利率期貨規避最有效;10年期公債以10年期利率期貨規避最有效;20年期公債以30年期利率期貨規避最有效。其避險效果約在60%至70%,顯示交叉避險仍存在無法避免的風險。
It is necessary and important for the hedge on Taiwan government bond because of the increasing trading volume and imminent bearish market. Although the 10-Year bond futures issue this year, it can’t satisfy hedgers for low trading volume and liquidity. Therefore, this study chooses the interest rate futures issued by CBOT to hedge Taiwan government bonds. Through cross hedging, to research which hedging model including Naïve hedge, OLS, ECM and GARCH model has the better hedge performance.
