【講座摘要】

　　原油價(jià)格變動(dòng)對社會經(jīng)濟(jì)影響深遠(yuǎn),，但供給和需求的變動(dòng)帶來的影響完全不同,。社會，企業(yè)都應(yīng)甄別應(yīng)對,。本文提議一種新的期權(quán)分析模式,，可用來及時(shí)，準(zhǔn)確判定供給和需求變動(dòng)對原油的動(dòng)態(tài)貢獻(xiàn),。分析表明,，2008年前油價(jià)變動(dòng)多有供給動(dòng)蕩引起，但之后需求動(dòng)蕩對油價(jià)的貢獻(xiàn)開始占主導(dǎo)地位,。2008年的金融危機(jī)引起一次大的需求震蕩,。之后的頁巖革命更是改變了 原油供給的舊次序，降低的供給震蕩,，使需求變動(dòng)成為主導(dǎo),。航空公司一直以來用石油期貨對沖燃油成本變動(dòng),。在需求主導(dǎo)的當(dāng)下,，應(yīng)當(dāng)減少對沖。

Oil price fluctuates in response to both demand and supply shocks. Major events and structural changes induce large variations in the intensity of the shocks and their relative contribution to the oil price movements. We propose a new methodology that allows timely identification of the shifting contribution from the two types of shock through a joint analysis of crude futures options and stock index options. Applying the methodology to historical data shows that crude futures price movements were dominated by supply shocks in the earlier half of our sample from 2004 to 2008, but have since become much more demand driven. The large demand shock following the 2008 financial crisis contributed to the start of this shift in the dynamics, while the subsequent rise of the shale revolution fundamentally altered the crude supply behavior.  The increasing U.S. shale oil production at a competitive cost has undercut the price-setting power of the OPEC, and lowered the OPEC's incentive to self-regulate its production. As a result of this dynamics shift, investors have shifted from being concerned with crude oil price hikes as a gauge of increasing production cost, to worrying about crude oil price declines as an indication of weakening demand. Identifying the time variation in the relative contribution of demand and supply shocks to crude oil prices can fundamentally improve the efficiency of fuel cost hedging decisions by heavy oil users such as the airline industry. We show that while hedging crude supply shocks can reduce bottom-line fluctuation due to fuel cost variation, hedging with crude futures becomes less desirable when its variation is mainly driven by demand shocks.
