Threshold Cointegration Analysis of Crude Oil Benchmarks

Shawkat M. Hammoudeh, Bradley T. Ewing and Mark A. Thompson

Year: 2008
Volume: Volume 29
Number: Number 4
DOI: 10.5547/ISSN0195-6574-EJ-Vol29-No4-4
View Abstract

The paper examines the dynamic relationship between pairs of four oil benchmark prices (i.e., West Texas Intermediate, Brent, Dubai, and Maya), which have different physical properties and locations. The results indicate that there is a long-run equilibrium relationship between different benchmarks, regardless of their properties and locations. More importantly, there is asymmetry in the adjustment process that is specifically modeled and implications are discussed.

Physical Markets, Paper Markets and the WTI-Brent Spread

Bahattin Buyuksahin, Thomas K. Lee, James T. Moser, and Michel A. Robe

Year: 2013
Volume: Volume 34
Number: Number 3
DOI: 10.5547/01956574.34.3.7
View Abstract

We document that, starting in the Fall of 2008, the benchmark West Texas Intermediate (WTI) crude oil has periodically traded at unheard-of discounts to the corresponding Brent benchmark. We further document that this discount is not reflected in spreads between Brent and other benchmarks that are directly comparable to WTI. Drawing on extant models linking oil inventory conditions to the futures term structure, we test empirically several conjectures about how calendar and commodity spreads (nearby vs. first-deferred WTI; nearby Brent vs. WTI) should move over time and be related to storage conditions at Cushing. We then investigate whether, after controlling for macroeconomic and physical market fundamentals, spread behavior is partly predicted by the aggregate oil futures positions of commodity index traders.

Location Basis Differentials in Crude Oil Prices

Phat V. Luong, Bruce Mizrach, and Yoichi Otsubo

Year: 2019
Volume: Volume 40
Number: Special Issue
DOI: 10.5547/01956574.40.SI2.pluo
View Abstract

We examine the long-run pricing relationship among crude oil prices at the North Sea (Brent) and Cushing (WTI) delivery points. The Brent-WTI location basis differential is stable until December 2009, but it widens to record levels in the next two years. We report on recent changes in the crude oil market that causes the prices to move apart. Brent and WTI prices are cointegrated prior to this structural break, but not between 2010 and 2015. Since the U.S. lifted the crude oil export ban in December 2015, Brent and WTI prices have reintegrated. U.S. retail gasoline prices respond to Brent and WTI before January 2010 and then only to Brent afterwards.

International Oil Market Risk Anticipations and the Cushing Bottleneck: Option-implied Evidence

Marie-Hélène Gagnon and Gabriel J. Power

Year: 2020
Volume: Volume 41
Number: Number 6
DOI: 10.5547/01956574.41.6.mgag
View Abstract

This paper studies crude oil market integration and spillovers between Brent and WTI oil indexes over the 2006�2019 period. In addition to prices, we estimate time series of model-free option-implied moments to capture forward-looking market views and anticipations of different risk categories. We describe the WTI-Brent equilibrium relationship in prices and in risk expectations measured by implied volatility, skewness, and kurtosis. Using a fractional cointegration model, we find long memory in the price cointegrating vector and in implied moments, implying that persistence of shocks is an important feature of crude oil markets. The evidence supports a differential in implied volatility but not in prices, and suggests equilibrium fragmentation during the Cushing bottleneck period. Analysis of implied moments reveals that Brent and WTI risk anticipations generally share a common equilibrium. Unlike volatility, asymmetric and tail risks are more locally driven, especially during market disruptions such as the Cushing bottleneck, so there is potential for diversifying extreme risks using both indexes.
