What is the Price of Oil? By Dr. Eric Girard Professor of Finance Hickey Chair in Business Director of the Center for Global Financial Studies
“Crude Processing” • Extraction-- Crude oil occur in the earth's crust as a result of a “million of years” decay of plants and animals. Once extracted, crude oil is transported to refineries, by ship and/or by pipeline. • The refining process-- Crude is separated into lighter groups of hydrocarbons--fuel oil , heating oil, and naphtha. • The chemistry process: naphtha is processed into olefins and aromatics; then transformed into more specialized products leading to plastic, rubber, detergents, aspirin, nylon and other synthetic fibers, paints, insulating materials...
What Price? • The crude oil price cycle may extend over several years responding to changes in demand as well as OPEC and non-OPEC supply (OPEC: Iran, Iraq, Kuwait, Saudi Arabia, Venezuela, Qatar, Indonesia, Libya, United Arab Emirates, Algeria and Nigeria). • Wide price swings in times of shortage or oversupply.
What Makes Oil Prices Swing? • Economic and Financial Forces (Consumption/ Demand) • Growth in Real GDP • Inflation • Strength of the Dollar • Reserves/Inventories • Crises and price controls • Political Forces (Production/Supply) • Wars • Conflicts • Regulations • Quotas, Embargos • Price controls
Market forces Vs. Price Controls: OPEC • OPEC has failed to time its increase/cuts in production quotas with world economic events. • Various members of OPEC produce beyond their quotas. • Non-OPEC members are producing at least as much as OPEC members.
What about Oil Reserves? Oil wells, Natural gas wells or dry holes. • Oil Reserves: Don’t know! A well guarded secret… • Lead-lag Test: oil prices weakly lead production efficiency… • In fact, technological and financial forces also affect production efficiency . • On the finance side: price risk is accounted for in the “decision to drill.” • Technological improvements have been tremendous– 3-D seismic data, directional and horizontal drilling; CO2 floods
Are Oil Prices too High? • On an inflation-adjusted basis—not really. • What happened since 2003? • Increasing demand in the US, China and India, coupled with lower US and OECD countries oil inventories. The world consumes over 100 million barrels a day • Storage and refining capabilities in the US affected by hurricane season. • Iraq war and Middle East tensions • loss of production capacity in OPEC (Venezuela and Iraq): In 2003 the excess production capacity was below 2 M, as compared to 6 M in 2002; in 2004 and 2005 under 1M barrels per day. Note that if oil is too expensive, economic growth stiffens and demand for oil decreases. In addition, R&D efforts support energy saving and replacement programs.
2 Markets and 2 Quotes for Oil? • Spot Prices • Current price Per Barrels • Reflects the current settlement in cash for oil barrels • Futures Prices • Commitment to Buy/sell at a price in the future (1 month, 2 months…from today) • NYMEX (“light sweet crude oil”) • 1 contract is for 1,000 barrels • Margin deposit only and margin maintenance requires • Huge leverage (>90%)
Who Leads Who: Spot or Futures Prices? • VAR/Generalized Impulse response
Pricing Oil -- Spot and Futures • The price or “intrinsic value” of an asset is the present value of its cash flow • For a commodity—not that easy to figure out. • Traditional factor models do not work--CAPM • Well, at least the market value reflects all forces on the demand and supply sides. • Why is there a spread?
What Does R mean? • R depends on Inflation, disruption of supply, disruption of consumption, cost of transportation, extraction, storage, storage insurance, etc… • It compensates for the forces/costs associated with owning/selling the commodity. • It is an opportunity cost adapted to changes in supply and demand for the commodity • Thus, it is time varying depending on changes in financial, economic and political risk of oil exporters and consumers
Building a Fundamental Models to Price Oil • Where a =0, b is the roll-over yield, • Zt-1 are lagged conditioning financial, economic and political variables affecting exporter and consumers of oil. • et is random noise
Applying the model • Monthly data (1985-2006) • Detrended (to get rid of the seasonal demand for the commodity) • Spot price • Conditioning variables: 44 oil exporters/importers weighted-average economic, financial and political risk ratings reduced with a factor analysis. In-the-sample characteristics: • R-squared 0.61 • Roll-over yield 0.81 • Exporter impact on oil prices 18 % • Importers impact on oil prices 11 % • Unconditioned effects 32 % • Unforeseeable events 39 % • Out-of-the sample forecast—2007: $71 +/- $3
Distribution of Unpredictable MovementsNormality is rejected at the 99% level
“Predictable” Unpredictable Price Movements? • 3 clues, 1 conclusion… • Strong (significant) autocorrelation (two lags) in residuals and squared residuals unexpected event occurrences are somewhat predictable. • A regime-switching model also shows that oil futures are prone to periodically bursting bubbles. • A GARCH analysis shows that the size of an unexpected event is more important than its direction; this can only happen when bubbles form and burst. • In sum, prices are determined by periodic herding behaviors unwarranted by fundamentals…
Distribution of Unpredictable Movements • On the left side (price decrease): fat tails, narrower mid-sections. • On the right side (price increase): larger mid-section, thin tail. • More month of price increase than price decrease (autocorrelation, RS, and GARCH tests) • Hedge funds behavior • Traders behavior (closing positions) • “Technicals” self-fulfilling behaviors • Herding behavior • End-of-the quarter behavior • End of the month behavior • End-of-the week behavior • Time of the day behavior • Contract maturity behavior • Option maturity behavior
Of Utmost Importance: Volume! • Volume: a proxy for information flow and a predictor of unforeseeable market events? • Tests (EGARCH): we use detrended Volume, then we brake it down into expected and unexpected volume… • Lagged Volume predicts volatility, not the opposite • Unexpected volume moves prices • Expected volume also moves prices, but reduces volatility asymmetric access to information there is a cluster of better informed traders!!!
Concluding remarks • Oil prices are moved by political, economic and financial factors affecting demanders and suppliers of oil…not so much changes in oil reserves and production efficiency. • A “conditioned” pricing model explains 61% of futures price movements—My Prediction $71 a barrel. • A sizable portion of price movements is attributable to traders’ behaviors • Volume traded is a strong determinant of oil price volatility • Oil trading strategy should focus on volatility changes rather than price changes… • Futures options strategy are more adapted to provide investors with a “winning” solution.
