【讲座摘要】

　　原油价格变动对社会经济影响深远，但供给和需求的变动带来的影响完全不同。社会，企业都应甄别应对。本文提议一种新的期权分析模式，可用来及时，准确判定供给和需求变动对原油的动态贡献。分析表明，2008年前油价变动多有供给动荡引起，但之后需求动荡对油价的贡献开始占主导地位。2008年的金融危机引起一次大的需求震荡。之后的页岩革命更是改变了 原油供给的旧次序，降低的供给震荡，使需求变动成为主导。航空公司一直以来用石油期货对冲燃油成本变动。在需求主导的当下，应当减少对冲。

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.
