How Crude Oil Affects Gas Prices

When the price of gas rises, it impacts how people travel, how goods are shipped, and how people formulate their budgets. For instance, when home heating prices climb, people have to decide whether or not they can afford to turn up their thermostats. Furthermore, when various goods have become more expensive because their components also cost more, people have to make difficult choices on what to buy.

One reason for these and other price fluctuations is the price of oil. The price of oil affects individual spending choices. It forces companies to make difficult decisions. It can even change relations between countries. Oil is perhaps the world’s most important natural resource and impacts the daily lives of people worldwide.

Crude Oil Origins

No one knows exactly how oil was created. But there are two theories that explain how the substance may have originated. The first theory suggests that oil is a fossil fuel, meaning it is composed of dead plants and animals that lived hundreds of millions of years ago. After decomposing over the eons, the chemical compounds of the remains broke down and formed what we now call oil.

Twentieth-century Russian scientists proposed another, « abiotic » theory, which states that oil comes from near the earth’s core, where it eventually flows, much like lava, into puddles underneath the earth’s crust.

Finding Crude Oil

Oil can be found on all of the earth’s continents. Some places, like Australia, have very little, but countries that have large reservoirs of oil are key players on the world stage. After all, they are sitting on top of pools of one of the most important global resources.

Oil is traditionally measured in barrels, and 1 barrel equals 42 gallons. Despite the world’s massive energy usage, experts think that there are still around 1.65 trillion barrels of oil reserves left in the ground

The nations that have most oil reserves include Venezuela (300 billion bl), Saudi Arabia (266.5 billion bl), and Canada (170.8 billion bl). Middle Eastern nations round out the top 10 all with sizable quantities, but have about one-half of what Saudi Arabia has in reserves. These nations include Iraq, Iran, Kuwait, and the United Arab Emirates. In total, the region’s vast supplies of oil make them an integral part of the world economy.

Canada, which has close to 171 billion barrels within its borders, has the third-largest amount of proven oil reserves in the world. However, nearly all of these reserves are located in Alberta’s « sand pits, » a terrain that makes the oil harder to extract from the earth than it is in other countries. However, technological innovations are expected to make extracting oil located in this kind of terrain easier. Other nations with large reservoirs of oil include Russia, Libya, the United States, Nigeria, and Kazakhstan.

Refining Crude Oil

Before oil can be used, it has to be broken down in a process known as « refining. » After being purchased, oil is shipped to various refineries around the world. In America, many (but certainly not all) of the oil refineries are located in the Gulf Coast region, with about 43% of America’s oil being produced in Texas. This is a reason why oil costs tend to fluctuate during storm season. A large hurricane, for example, puts oil supplied at the refineries at risk of destruction.

Refining oil works in a relatively easy way. Crude oil is put into a boiler and turned into a vapor. From there, the vapor moves into a distillation chamber, where it is turned back into a liquid. Different types of oil are formed depending upon the temperature they were distilled at. Gasoline, for example, is distilled at cooler temperatures than residual oils that are used to make products, such as asphalt and tar. After the many substances made from oil are processed, they arrive in various products to do a little bit of everything, from heating homes to powering cars.

Oil Uses

It makes sense that the world’s biggest economies would use the most oil. America, which has the world’s biggest gross domestic product (GDP), also consumes more oil than any other nation. The U.S. uses over 20% of the estimated 100 million barrels of oil produced around the world every day.

The phrase « America’s dependence on foreign oil » is mentioned often in the media, particularly in reference to American imports from the Middle East. However, this statement doesn’t accurately tell who supplies the U.S. with oil. About one-third of all of the oil America uses comes from reserves found domestically in the 50 states. The country that exports the most oil to America is Canada, with Saudi Arabia in second.

The European Union (EU) also uses a large percentage of the world’s reserves, going through approximately 14.5 million barrels daily in the 2010s. Other nations who have large, established economies—Japan, Canada, and South Korea—rank high on the list of the world’s biggest oil consumers.

China is one country that may play the biggest role in world oil consumption. China currently ranks as the second-biggest oil consumer on the planet. But with its dynamic and fast-growing economy, China’s usage of oil is forecasted to grow exponentially. Analysts have said that China’s demand for oil grows by approximately 7.5% a year.

This increased demand—along with the growing energy needs of countries like India and Brazil—has been a contributing factor in the rise of oil prices over the past few years. These countries act as the demand for the world’s oil supplies. However, the way oil is priced does not reflect that of the free market.

OPEC’s Impact on Oil

One body has great influence over the worldwide price of oil. The Organization of Petroleum Exporting Countries, more commonly known as OPEC, is a cartel made up of 13 of the world’s biggest oil-producing nations, including all of the major Middle Eastern states, Venezuela, and Nigeria. According to OPEC, this cartel controls 78% of the world’s known oil reserves. The major oil producers not in OPEC include Russia, Canada, and the U.S.

Since the OPEC nations produce so much of the world’s oil supply, they can manipulate the price per barrel depending upon how many barrels per day the group will sell on the world oil market. If the group wants the price to rise in order to make more money, they can reduce the amount of oil contributed to the world market. And if they want the price to dip—high energy prices drive down demand from OPEC’s consumers—they can release more barrels to the market.

While Canada, Russia, America, and other producers can also increase supply, they cannot affect world prices nearly as much as OPEC.

Types of Oil and Pricing

One might assume there is only one type of oil, but that’s far from the truth: There are 161 different types, each with its own consistency, chemical breakdown, and potential for use.

Even though there are so many forms of oil, we typically cite only one price for a barrel. This is because oil traders have selected the most widely used types of oil to determine the price per barrel. For instance, one common type of oil found and used in America is called West Texas Intermediate (WTI). West Texas Intermediate’s popularity is due to it being a « light and sweet » oil, which is easy to break down in the refining process. Since this oil is purchased quite frequently, it is used as an industry standard.

Other price benchmarks are used globally. Most European nations use the Brent Blend, found in the North Sea, as their benchmark price. Another heavily used benchmark is the OPEC basket, which combines the prices of several other popular types of oil from around the world into a « price basket. »

And while oil can be purchased directly (in what is called the spot market), the commonly cited price per barrel does not reflect what a customer pays. Instead, the price bandied about has been sold on the futures market. In America, WTI crude oil futures are traded through the New York Mercantile Exchange (NYMEX). European oil futures are sold through Intercontinental Exchange’s London branch. Globex is another popular commodities market where oil futures change hands.

Oil and Gas Correlation

There is a limited positive correlation between crude oil and natural gas prices. It seems logical there would be a positive correlation between the commodities, especially since natural gas is often a byproduct of drilling for crude oil. While at times crude oil and natural gas have had a positive correlation, the markets for each commodity are substantially different and subject to different fundamental forces. Statistical analysis shows there are periods of positive correlation, but generally, the two have limited correlation.

Natural Gas and Oil Correlation

The correlation coefficient is a statistical measure of the extent to which the price of natural gas and crude oil move together. It is also a measure of the degree to which the prices move together. The correlation coefficient is measured on a scale of -1 to +1. A measure of +1 indicates a perfect positive correlation between two asset prices, meaning the prices of the assets move together in the same direction to the same degree proportionally all of the time.

A measure of -1 indicates a perfect negative correlation. This means the asset prices move in the opposite direction of each other in the same proportion all of the time. If the correlation coefficient is zero, it means there is no relationship between the two prices. The correlation coefficient is often used in the construction of portfolios by providing a statistical measure of the diversification of the assets in the portfolio.

Oil and Gas Data Sources

The Energy Information Administration (EIA) provides historical data for the daily correlation between commodities on a quarterly basis. This information indicates the correlation between crude oil and natural gas is falling. For example, in 2004, the average quarterly correlation between the two prices was around 0.45. This is a moderate positive correlation.

In 2010, this correlation average fell to -0.006, showing there was very little relationship between the prices. In 2014, the average correlation was 0.075. This also indicates very little correlation. However, the first two quarters of 2015 show an average correlation of 0.195, which is slightly positive. Prices for both commodities generally fell during this period. However, the data shows very little correlation between 2009 and 2020, apart from irregular quarters

The highest correlation was in the third quarter of 2005 with a measure of 0.699. The lowest correlation was in the third quarter of 2010 with a negative correlation of -0.21. In general, the correlation is falling. The EIA notes this is due to the increase in shale oil natural gas production.

Gas Production and Oil

Natural gas oil production has increased dramatically with the discovery of new shale drilling technologies. Between 2007 and 2012, natural gas production from shale drilling rose by a whopping 417% and overall production increased by around 20% during the same period. Natural gas prices have shown greater volatility historically than crude oil prices, while low natural gas prices have led sectors such as the transportation industry to use more natural gas over crude oil.

Production then remained stable, rising slightly year-over-year from 2012 through 2019. In 2020, amid the COVID19 pandemic, however, crude production dropped to 2013 levels.

Prices and Oil Production

Shale drilling technologies have also led to expanded crude oil production in North America. Daily crude oil production increased from 5.35 million barrels per day in 2009 to 6.5 million barrels in 2012. Production in 2014 grew even more to 8.7 million barrels a day. In 2019, production rose to a record 12.3 million barrels per day, with a slight decrease in 2020 due to the COVID19 pandemic.

Increased production can lead to a dip in oil prices given steady demand. Since oil is sold on a global market, even concerted efforts by groups like OPEC can only influence the price modestly, and only for short periods.

The Bottom Line

Oil is one of the world’s most important commodities. As a result, the nations that control the bulk of the world’s supply have (and exercise) a great deal of power over its availability. The supply of oil in the world market has an impact on its price, and the fluctuations are passed on to consumers, especially in nations that use a lot of oil, such as the U.S.

Oil prices are also determined by the quality and ease of refining. Investors have the option of investing in oil futures, which themselves have an influence on the price of oil that is reported. The oil market is quite complex, and a better understanding of how oil gets to you from the ground in all its forms will help you to understand and deal with fluctuating prices.
