The problem of modeling oil prices over the last three decades is analyzed. Because of radical changes of regimes on the oil market necessity of studying two periods of time (the 1980’s to the end of 1990’s and the end of 1990’s to 2008) is discussed. Two aggregate models reflecting the...

Using the prices of crude oil futures contracts, we construct the term structure of crude oil convenience yields out to one-year maturity. The crude oil convenience yield can be interpreted as the interest rate, denominated in barrels of oil, for borrowing a single barrel of oil, and it measures...

This paper analyses futures prices for four energy commodities (light sweet crude oil, heating oil, gasoline and natural gas) and five agricultural commodities (corn, oats, soybean oil, soybeans and wheat), over the period 1986-2010. Using CCC and DCC multivariate GARCH models, we find that...

Le rapport fait le point sur les interactions entre la volatilité des prix du pétrole et les stratégies des acteurs financiers. Il présente également les réflexions et actions en cours au niveau international pour améliorer le fonctionnement des marchés pétroliers. Et au final, il...

Do events in the natural gas market cause repercussions in the crude oil market? This paper studies linkages between the two markets using high-frequency, intraday oil and gas futures prices. By analyzing the effect of weekly oil and gas inventory announcements on price volatility, we show a...

This paper examines the relationship between spot and futures prices for a broad range of commodities, including energy, precious and base metals, and agricultural commodities. In particular, we examine whether futures prices are (1) an unbiased and/or (2) accurate predictor of subsequent spot...

This paper evaluates how different types of speculation affect the volatility of commodities’ futures prices. We adopt four indexes of speculation: Working’s T, the market share of non-commercial traders, the percentage of net long speculators over total open interest in future markets,...

This paper examines the relationship between spot and futures prices for energy commodities (crude oil, gasoline, heating oil markets and natural gas). In particular, we examine whether futures prices are (1) an unbiased and/or (2) accurate predictor of subsequent spot prices. We find that while...

This paper analyzes the relationship between the spot and futures prices of energy commodities from a new perspective. Taking data from the Dow Jones UBS Commodity Index, we first test for a long-run relationship between spot and futures prices. As a second step, smooth transition models are...
