The Relationship Between Oil Prices and the Stock Market

The Relationship Between Oil Prices and the Stock Market

4 Min.

Researchers from the Federal Reserve Bank of Cleveland conducted a study to examine the relationship between oil prices and the stock market. They found that there is little correlation between the two, challenging the conventional wisdom that higher oil prices lead to lower stock market performance. While oil prices do affect the economy in various ways, the stock market's complexity and multiple influencing factors make it hard to predict how oil prices will impact it.


The relationship between oil prices and the stock market has been a topic of interest for many investors and analysts. Common belief suggests that when oil prices rise, it increases input costs for businesses, which can lead to reduced corporate earnings and, consequently, a negative impact on stock market performance. Conversely, when oil prices fall, it is expected to have a positive effect on the stock market.

Andrea Pescatori's Study

In 2008, Andrea Pescatori, an economist at the International Monetary Fund (IMF), attempted to test this theory. He used changes in the S&P 500 as a proxy for stock prices and crude oil prices for his study. Pescatori's findings were surprising; he discovered that these two variables only occasionally moved in the same direction, and even when they did, the relationship was weak, with no statistically significant correlation.

Impact on the U.S. Economy

The impact of oil prices on the U.S. economy is not one-dimensional. High oil prices can lead to job creation and investment, particularly in oil companies exploiting higher-cost shale oil deposits. However, they can also impose higher transportation and manufacturing costs on businesses and consumers. On the other hand, lower oil prices negatively affect unconventional oil activity but can benefit manufacturing and other sectors with a strong reliance on low fuel costs.

Oil and the Cost of Doing Business

Historically, drops in oil prices were seen as positive because they reduced the cost of importing oil and lowered manufacturing and transportation costs. This, in turn, benefited consumers by increasing their disposable income. However, with the resurgence of U.S. oil production, low oil prices can negatively impact domestic oil companies and industry workers.

Factors Influencing Stock Prices

While many believe that oil prices should drive stock prices, it is important to consider that stock prices are influenced by a multitude of factors. These include future corporate earnings reports, intrinsic values, investor risk tolerances, and various other elements. Oil prices are just one among many, and their impact can vary across different sectors of the stock market.

Why Oil Doesn't Drive Stock Prices

Several reasons explain why Federal Reserve economists couldn't find a stronger correlation between oil prices and the stock market:

  • Sophisticated Corporations: Corporations have become increasingly sophisticated at reading futures markets and can anticipate shifts in factor prices. They can adjust their production processes to counteract added fuel costs, reducing the direct impact of oil price changes.
  • Quantity of Money: Some economists argue that general stock prices often rise based on the expectation of an increase in the quantity of money, which is independent of oil prices.
  • Multiple Influencing Factors: The economy is a complex interplay of various factors, including wages, interest rates, industrial metals, plastics, and technology. These factors can offset changes in energy costs, making it challenging to attribute stock market movements solely to oil prices.
  • Sector Variability: Different sectors within the stock market react differently to changes in oil prices. It's possible that oil prices significantly affect certain sectors while having a minimal impact on others, further complicating the correlation.

Oil Prices and Transportation

One sector of the stock market that does show a strong correlation with oil prices is transportation. Transportation companies heavily rely on fuel as a primary input cost, so when oil prices rise, it can have a detrimental effect on their performance. Investors may consider shorting transportation stocks when oil prices are high and buying when they are low. However, the future impact of electric vehicles on the transportation sector remains uncertain.


While there is a common belief that oil prices directly impact the stock market, research suggests that the relationship between the two is complex and not easily predictable. Studies have shown that the correlation between oil prices and stock market performance is weak, with many other factors influencing stock prices. While certain sectors like transportation are more directly affected by oil prices, the overall impact on the stock market is not significant. It is important for investors and analysts to consider a wide range of factors when assessing stock market movements, rather than relying solely on oil prices as a predictor.
