Abstract (EN)
Whereas the spatial integration has already been examined in commodity markets,
empirical tests on temporal integration have never been carried out. Relying on the “preferred habitat”
theory, which is applied to the crude oil market, this article investigates whether this market is
segmented or not. Segmentation is defined as a situation in which different parts of the prices curve
are disconnected from each other. Consequently, the information conveyed by certain prices is useless
when reconstituting the rest of the curve. Empirical tests are carried out with a term structure model,
the performances of which depend on the informational value of the prices retained for the estimation.
We show that the crude oil futures market is segmented into three parts. The first corresponds to
maturities below 28 months, the second is situated between the 29th
and 47th
months, and the third
consists of maturities ranging from the 4th
to 7th
years.
