Abstract:
This paper looks at speculative behavior in the international oil market. Much of the blame for oil-market turbulence has been placed on speculators, particularly hedge funds. Speculative capital has been characterized as “hot money,” with capital flows driven by “herding,” “flocking,” and “contagion.” Policies to deal with volatility by weakening, or even disabling speculation, have been based largely on anecdote, convenience (speculators have long served as scapegoats for various problems), and ideology, rather than careful analysis. Part of the problem arises from the secrecy with which speculators operate. Because speculative trading cannot easily be observed, it is difficult to assess speculators’ contribution, if any, to volatility. The paper utilizes a large, detailed database on individual trader positions in crude-oil and heating-oil futures markets. The paper is exploratory, with focus on measuring and assessing the tendency of speculators to herd (trade in the same direction as a group) and flock (trade in the same direction by subgroups of speculators).
