摘要
對於近年來,石油輸出國組織(OPEC)與美國頁岩油業者陷入產量的競爭,石油價格變動幅度加劇,布蘭特原油(Brent)價格自97.34美元(2012年7月2日),跌落至50.35美元(2016年7月1日) ,跌幅約45.19%。
本研究主要探討在油價如此大幅度的波動之下,對財富管理銀行認為的原油相關貨幣[加幣(CAD)、俄羅斯盧布(RUB)、澳幣(AUD) 、英鎊(GBP) ]所帶來的影響程度及常被用來避險的黃金(XAU)、日幣(JPY) ,還有代表股市的道瓊工業平均指數(DJIA) 、放空避險的恐慌指數(VIX) ,在油價大幅波動時的相互表現做探討與預測。
採用各變數日資料,以Granger causality、Impulse response與Variance decomposition來分析。經實證可知,在布蘭特原油大幅波動期間:
(1)日幣會影響道瓊工業平均指數,澳幣會影響英鎊,英鎊會影響日幣,英鎊會影響恐慌指數;而恐慌指數與俄羅斯盧布彼此存在雙向關係,俄羅斯盧布與道瓊工業平均指數彼此存在雙向關係,而加幣對黃金、恐慌指數、日幣、道瓊工業平均指數皆存在雙向關係。
(2) 當各變數分別發生自發性干擾時,其衝擊反應效果在第1期效果最大,自第3、4期後才會消失。。
(3) 發生非預期的變動之變異時;澳幣可被其本身解釋的比例較高、加幣可被道瓊工業平均指數及黃金現貨解釋的比例較高。道瓊工業平均指數可被澳幣解釋的比例較高。英鎊可被澳幣解釋的比例較高。日幣可被道瓊工業平均指數及澳幣解釋的比例較高。俄羅斯盧布可被澳幣及道瓊工業平均指數解釋的比例較高。恐慌指數可被澳幣解釋的比例較高。黃金現貨可被澳幣及道瓊工業平均指數解釋的比例較高。
SUMMARY
In recent years, the prices of petroleum have changed dramatically due to the production competition between OPEC and US shale oil industry. The price of Brent had declined from $97.34 USD (7/2/2012) to $50.35 USD (7/1/2016), with a drop of 45.19%.
The purpose of this research is to investigate the influence of dramatic petroleum price changes on petroleum-related currencies, such as CAD, RUB, AUD, and GBP for financial management banks and to explore and predict the mutual performance of gold (XAU), JPY, which are often used for avoiding risks, DJIA, the representative of stock market, and Volatility Index (VIX) for empty hedge when the prices of petroleum change dramatically.
Granger Causality, Impulse Response, and Variance Decomposition were utilized to analyze daily variable data. Empirical analysis discovered the following results:
(1) JPY had impact on DJIA, AUD on GBP, GBP on JPY and VIX, while VIX and RUB had bilateral relationships and RUB and DJIA had bilateral relationship as well. Moreover, CAD had bilateral relationships with gold (XAU), VIX, JPY, and DJIA.
(2) The Impulse Response was at its peak in the first stage when spontaneous interference occurred in each variable and disappeared after the third and fourth stages.
(3) When unexpected changes occurred, AUD had a higher ratio of being interpreted by itself, while CAD had a higher ratio of being interpreted by DJIA and spot gold. DJIA had a higher ratio of being interpreted by AUD, GBP by AUD, and JPY by DJIA and AUD. RUB had a higher ratio of being interpreted by AUD and DJIA, VIX by AUD, and spot gold by AUD and DJIA.
