Crude Oil

What Is Crude Oil?

Crude oil is a naturally occurring liquid petroleum product composed of hydrocarbon deposits and other organic materials formed from the remains of animals and plants that lived millions of years ago. These organisms were covered by layers of sand, silt, and rock, subject to heat and pressure, and eventually turned into a type of fossil fuel that is refined into usable products including gasoline, diesel, liquefied petroleum gases, and feedstock for the petrochemical industry.

Crude oil is a nonrenewable resource, which means that it can't be replaced naturally at the rate we consume it and is, therefore, a limited resource.

Key Takeaways

  • Crude oil is a raw natural resource that is extracted from the earth and refined into products such as gasoline, jet fuel, and other petroleum products.
  • It is composed of hydrocarbon deposits and other organic materials that were formed from the remains of animals and plants that lived millions of years ago.
  • Petroleum is a more general word that refers to crude oil, the raw oil that is extracted out of the ground, and other products formed from refined crude oil.
  • Crude oil is a global commodity that trades in markets around the world, both as spot oil and via derivatives contracts.
  • Many economists view crude oil as the single most important commodity in the world, as it is currently the primary source of energy production.

Understanding Crude Oil

Crude oil is typically obtained through drilling, where it is usually found alongside other resources, such as natural gas (which is lighter and therefore sits above the crude oil) and saline water (which is denser and sinks below). After its extraction, crude oil is refined and processed into a variety of forms, such as gasoline, kerosene, and asphalt, for sale to consumers.

Crude oil is one of the world's most important commodities and its price can have ripple effects through the broader economy. Rising oil prices mean higher gasoline prices at the pump, higher shipping costs, and increased input costs for producers. Crude oil prices are driven mainly by the principles of supply and demand. Oversupply and shrinking demand lower prices, while rising demand and short supply pushes prices up. Perceived supply and demand changes can be driven by geopolitical events or natural disasters that affect oil-producing nations.

Investors and speculators can trade oil via futures markets, spot markets, or exchange traded funds (ETFs).

A Historical View

Although fossil fuels such as coal have been harvested for centuries, crude oil was first discovered and developed during the Industrial Revolution, and its industrial uses were developed in the 19th century. Newly invented machines revolutionized the way we do work, and they depended on these resources to run. Today, the world's economy is largely dependent on fossil fuels such as crude oil, and the demand for these resources often sparks political unrest, as a small number of countries control the largest reservoirs. Like any industry, supply and demand heavily affect the prices and profitability of crude oil. The U.S., Saudi Arabia, and Russia are the leading producers of oil in the world.

In the late 19th and early 20th centuries, the U.S. was one of the world's leading oil producers, and U.S. companies developed the technology to make oil into useful products like gasoline. During the middle and last decades of the 20th century, U.S. oil production fell dramatically, and the U.S. became an energy importer, although in 2021 crude oil net imports were at the second-lowest annual level since 1985.

Its major supplier was the Organization of the Petroleum Exporting Countries (OPEC), founded in 1960, which consists of the world's largest (by volume) holders of crude oil and natural gas reserves. As such, the OPEC nations had a great deal of economic leverage in determining supply, and therefore the price, of oil in the late 20th century.

In the early 21st century, the development of new technology, particularly hydro-fracturing, known as "fracking," created a second U.S. energy boom, largely decreasing OPEC's importance and influence. Heavy reliance on fossil fuels is cited as one of the main causes of global warming, a topic that has gained traction in the past several decades. Risks surrounding oil drilling include oil spills and ocean acidification, which damage the ecosystem. Also in the 21st century, many manufacturers have begun creating products that rely on alternative sources of energy, such as cars run by electricity, homes powered by solar panels, and communities powered by wind turbines.

Oil is often called "black gold," yet crude oil has a range of viscosity and can vary in color from black to yellow depending on its hydrocarbon composition. Distillation, the process by which oil is heated and separated into different components, is the first stage in refining.

Crude Oil vs Petroleum

Petroleum, a name that comes from the Latin words “petra,” meaning rock, and “oleum,” meaning oil, is often used interchangeably with crude oil. Essentially, petroleum is a more general word that refers to crude oil, the raw, unprocessed oil that is extracted out of the ground, and other petroleum products formed from refined crude oil.

Petroleum products cover everything a refinery produces from crude oil or natural gas. These products include diesel, gasoline, fuel oil, and more.

Investing in Oil

Investors may purchase two types of oil contracts: futures contracts and spot contracts. To the individual investor, oil can be a speculative asset, a portfolio diversifier, or a hedge against related positions.

Spot Contracts

The price of the spot contract reflects the current market price for oil, whereas the futures price reflects the price buyers are willing to pay for oil on a delivery date set at some point in the future.

The futures price is no guarantee that oil will actually hit that price in the current market when that date comes. It is just the price that, at the time of the contract, purchasers of oil are anticipating. The actual price of oil on that date depends on many factors.

Most commodity contracts that are bought and sold on the spot markets take effect immediately: Money is exchanged, and the purchaser accepts delivery of the goods. In the case of oil, the demand for immediate delivery versus future delivery is limited, in no small part due to the logistics of transporting oil.

Investors, of course, don't intend to take delivery of commodities at all (although there have been cases of investor errors that have resulted in unexpected deliveries), so futures contracts are more commonly used by traders and investors.

Futures Contracts

An oil futures contract is an agreement to buy or sell a certain number of barrels of oil at a predetermined price, on a predetermined date. When futures are purchased, a contract between buyer and seller is signed and secured with a margin payment that covers a percentage of the total value of the contract.

End-users of oil purchase on the futures market in order to lock in a price; investors buy futures essentially as a gamble on what the price will actually be down the road, and they profit if they guess correctly. Typically, they will liquidate or roll over their futures holdings before they would have to take delivery.

There are two major oil contracts that are closely watched by oil market participants. In North America, the benchmark for oil futures is West Texas Intermediate (WTI) crude, which trades on the New York Mercantile Exchange (Nymex). In Europe, Africa, and the Middle East, the benchmark is North Sea Brent Crude, which trades on the Intercontinental Exchange (ICE).

While the two contracts move somewhat in unison, WTI is more sensitive to American economic developments, and Brent responds more to those in other countries.

There are multiple futures contracts open at once, with most trading in the front-month contract (the nearest futures contract). For this reason, the front month is also known as the most active contract.

Spot vs. Future Oil Prices

Futures prices for crude oil can be higher, lower, or equal to spot prices. The price difference between the spot market and the futures market says something about the overall state of the oil market and expectations for it. If the futures prices are higher than the spot prices, this usually means that purchasers expect the market will improve, so they are willing to pay a premium for oil to be delivered at a future date. If the futures prices are lower than the spot prices, this means that buyers expect the market to deteriorate.

"Backwardation" and "contango" are two terms used to describe the relationship between expected future spot prices and actual futures prices. When a market is in contango, the futures price is above the expected spot price. When a market is in normal backwardation, the futures price is below the expected future spot price. The prices of different futures contracts can also vary depending on their projected delivery dates.

Forecasting Oil Prices

Economists and experts are hard-pressed to predict the path of crude oil prices, which are volatile and depend on many variables. They use a range of forecasting tools and depend on time to confirm or disprove their predictions. The five models used most often are:

  1. Oil futures prices: Central banks and the International Monetary Fund (IMF) mainly use oil futures contract prices as their gauge. Traders in crude oil futures set prices by two factors: supply and demand and market sentiment. However, futures prices can be a poor predictor, because they tend to add too much variance to the current price of oil.
  2. Regression-based structural models: Statistical computer programming calculates the probabilities of certain behaviors on the price of oil. For instance, mathematicians may consider forces such as events in OPEC member nations, inventory levels, production costs, or consumption levels. Regression-based models have strong predictive power, but their creators may fail to include one or more factors, or unexpected variables may step in to cause these regression-based models to fail.
  3. Time-series analysis: Some economists use time-series models, such as exponential smoothing models and autoregressive models, which include the categories of ARIMA and the ARCH/GARCH, to correct for the limitations of oil futures prices. These models analyze the history of oil at various points in time to extract meaningful statistics and predict future values based on previously observed values. Time-series analysis sometimes errs, but usually produces more accurate results when economists apply it to shorter time spans.
  4. Bayesian autoregressive models: One way to improve upon the standard regression-based model is by adding calculations to gauge the probability of the impact of certain predicted events on oil. Most contemporary economists like to use the Bayesian vector autoregressive (BVAR) model for predicting oil prices.
  5. Dynamic stochastic general equilibrium graphs: Dynamic stochastic general equilibrium (DSGE) models use macroeconomic principles to explain complex economic phenomena—in this case, oil prices. DSGE models sometimes work, but their success depends on events and policies remaining unchanged, as DSGE calculations are based on historical observations.

Each mathematical model is time-dependent, and some models work better at one time than another. Because no one model alone offers a reliably accurate prediction, economists often use a weighted combination of them all to get the most accurate answer. In 2014, for instance, the European Central Bank (ECB) used a four-model combination to predict the course of oil prices to generate a more accurate forecast. There have been times, however, when the ECB has used fewer or more models to capture the best results. Even so, unforeseen factors like natural disasters, political events, or social upheavals can derail the most careful of calculations.

Oil Industry Information

Because crude oil prices are constantly changing and are typically more volatile than stock or currency prices, it is crucial for successful investors and traders to have good information sources that report on the many factors that can influence oil prices. There are many websites that report crude oil news, but only a few broadcast the breaking news and current prices. The following three offer current information.

  1. MarketWatch: MarketWatch provides a wide range of business news, personal finance information, real-time commentary, investment tools, and data. Despite covering all aspects of financial markets, it tends to be among the first to break stories, putting out headlines as soon as news hits. These headlines can be found at the top right of its home page under the tab "Latest." MarketWatch also provides details when necessary, posting stories, sometimes only a paragraph or two, to elaborate on its headlines, and updating them throughout the day. The site provides current oil price information, stories detailing oil's price path—including pre-market and closing bell commentary—and multiple feature articles. The site has an active link on its landing page showing the price of WTI oil. Within most articles, MarketWatch also includes an active link to the price of oil, so when you read an article the price quote included is current. In addition, MarketWatch offers a more in-depth analysis of the economic news driving oil prices.
  2. Reuters Commodities Page: The Reuters news service has a commodity-specific portion of its website that releases breaking oil news, background stories, and current prices. It also offers more recent in-depth stories on, and analysis of, the sector as a whole, including price-driving sector updates, and is good at releasing any imperative news as it is made public. Reuters also publishes frequent pieces detailing oil's price movements and the factors behind those movements.
  3. CNBC: CNBC.com has a webpage dedicated to oil news. During U.S. market hours, it publishes relevant oil-specific pieces. This works out to be about every hour when you look at its main page. CNBC frequently updates its articles when there is a price movement in oil, but it does not provide a live feed to oil prices like MarketWatch does. It makes up for this, though, by providing a good breadth of oil sector stories, including all major price movers and price-driving developments.

How Does One Invest in Crude Oil?

To an investor, crude oil can be a speculative asset, a portfolio diversifier, or a hedge against related positions. There are two ways to invest in crude oil: futures contracts and spot contracts. The price of the spot contract reflects the current market price for oil, whereas the futures price reflects the price buyers are willing to pay for oil on a delivery date set at some point in the future.

What Can Spot and Futures Crude Oil Prices Tell an Investor?

The basis, or differences, between oil futures contracts and the spot (cash) market can be indicative of the near-term expectations of oil supply and demand. When futures prices are trading higher than the spot (known as contango), it suggests that traders are willing to pay a premium for oil to be delivered at a future date and that expectations are bullish. If, instead, futures are trading below the spot (known as backwardation), it can be a bearish signal.

How Can I Follow the Crude Oil Industry?

Crude oil prices and related market news is available online, often for free. MarketWatch, for example, provides up-to-date price quotes, headlines, and commentary. The site has an active link on its landing page showing the price of crude. Reuters news service is another free site with a commodity-specific portion that shows current prices. CNBC.com, too, has a page dedicated to oil-specific news and recent developments.

What Countries Are Members of OPEC?

According to its statutes, OPEC membership is open to any country that is a substantial exporter of oil and shares the ideals of the organization. After the five founding members, OPEC grew by 11 additional member countries as of 2019. They are, in order of joining, as follows:

  • Iran (1960)
  • Iraq (1960)
  • Kuwait (1960)
  • Saudi Arabia (1960)
  • Venezuela (1960)
  • Qatar (1961)
  • Indonesia (1962)
  • Libya (1962)
  • United Arab Emirates (1967)
  • Algeria (1969)
  • Nigeria (1971)
  • Ecuador (1973)
  • Gabon (1975)
  • Angola (2007)
  • Equatorial Guinea (2017)
  • Congo (2018)

Ecuador withdrew from the organization on Jan. 1, 2020. Qatar terminated its membership on Jan. 1, 2019, and Indonesia suspended its membership on Nov. 30, 2016, so as of 2022, the organization consists of 13 states.

The Bottom Line

The importance of crude oil cannot be overstated. It is a major source of energy, generating heat and powering various types of vehicles and machinery, and is also used as a component in many of the products we use every day, including plastics, paints, and cosmetics.

Concerns about the damage it does to the environment mean crude oil isn't favorable with everyone. However, most agree that we currently cannot live without it and that no longer extracting and refining crude oil would lead the global economy to grind to a halt.
