The role of speculation in oil markets: What have we learned so far

Abstract: A popular view is that the surge in the price of oil during 2003-08 cannot be explained by economic fundamentals, but was caused by the increased financialization of oil futures markets, which in turn allowed speculation to become a major determinant of the spot price of oil. This interpretation has been driving policy efforts to regulate oil futures markets. This survey reviews the evidence supporting this view. We identify six strands in the literature corresponding to different empirical methodologies and discuss to what extent each approach sheds light on the role of speculation. We find that the existing evidence is not supportive of an important role of speculation in driving the spot price of oil after 2003. Instead, there is strong evidence that the co-movement between spot and futures prices reflects common economic fundamentals rather than the financialization of oil futures markets.(This abstract was borrowed from another version of this item.)

The relationship between spot and futures prices: Evidence from the crude oil market

Abstract: This article examines the relationship between the spot and futures prices of WTI crude oil using a sample of daily data. Linear causality testing reveals that futures prices lead spot prices, but nonlinear causality testing reveals a bidirectional effect. This result suggests that both spot and futures markets react simultaneously to new information. © 1999 John Wiley & Sons, Inc. Jrl Fut Mark 19: 175–193, 1999

Valuation of Commodity Futures and Options under Stochastic Convenience Yields, Interest Rates, and Jump Diffusions in the Spot

Abstract: This paper investigates the effects of stochastic convenience yields, stochastic interest rates, and jumps in the spot price on the pricing of commodity futures, forwards, and futures options. Numerical examples show that one-factor prices differ materially from the stochastic convenience yield two-factor prices when convenience yield is considerably above its long-term average. The extension to a three-factor model with stochastic interest rates leads to a different futures price but the forward price is unchanged. The extension ofthe three-factor model to include jumps in the spot price process does not affect forward or futures prices but it can have an impact on options prices. The model is applied to price the present value of future cash flows from a real asset.

Periodic seasonal reg-ARFIMA-GARCH models for daily electricity spot prices

Abstract: Novel periodic extensions of dynamic long-memory regression models with autoregressive conditional heteroscedastic errors are considered for the analysis of daily electricity spot prices. The parameters of the model with mean and variance specifications are estimated simultaneously by the method of approximate maximum likelihood. The methods are implemented for time series of 1,200–4,400 daily price observations in four European power markets. Apart from persistence, heteroscedasticity, and extreme observations in prices, a novel empirical finding is the importance of day-of-the-week periodicity in the autocovariance function of electricity spot prices. In particular, the very persistent daily log prices from the Nord Pool power exchange of Norway are effectively modeled by our framework, which is also extended with explanatory variables to capture supply-and-demand effects. The daily log prices of the other three electricity markets—EEX in Germany, Powernext in France, and APX in The Netherlands—are less...
