How Crude Oil Affects Natural Gas Prices

Understanding how crude oil affects natural gas prices is crucial for commodity traders or anyone interested in energy commodities. Both are foundational and highly-traded global energy commodities, and have historically shared a relationship (mostly positive), although the correlation has weakened over the last few years. Let us examine all these aspects in more detail below.

Overview of Crude Oil and Natural Gas as Energy Commodities

Crude oil and natural gas are both highly traded global fossil fuel commodities that contribute more than 50% of global primary energy consumption.

Natural gas is vital for generating electricity, industry, and heating, while crude oil is mainly used for manufacturing and transportation. Both of these strategic yet volatile assets are also mainly driven by demand-supply factors and geopolitics.

Crude oil is often known as the mother of commodities and is the primary fuel for transportation. It is highly liquid and is traded worldwide (WTI, Brent, etc.), with considerable futures and options volumes. 

Natural gas is mainly for industrial heating, cooking, and power generation, being the cleaner fuel of the two. It is transported as LNG (liquefied natural gas) or through pipelines, and its prices are also driven by weather, inventory levels, supply imbalances, and geopolitical events. 

Lower prices may lead to higher consumer spending and industrial growth, while higher prices directly contribute to inflation. They are actively traded on exchanges like the MCX. It is usually easier to transport and store crude oil than natural gas. 

Historical Relationship Between Crude Oil and Natural Gas Prices

Here are some aspects that may give you a better idea about the relationship between crude oil and natural gas: 

• Traditionally, natural gas prices were either indexed or directly linked to crude oil prices. A positive, robust correlation was observed between 2003 and 2008. 
• Since 2009, the relationship has been weakening, with commodities often moving independently of each other. This can be attributed to the boom in shale gas, which has led to higher supply and less interdependence between the two commodities. 
• Since natural gas is mostly an oil-drilling byproduct, periods of higher oil prices or increased production may lead to natural gas oversupply in some cases. It may lead to price drops, even as oil prices rise. 
• Since commodities may substitute for each other in power generation or industry, a spike in one may lead to a rise in the other. 
• The relationship is usually perceived as a non-linear one today, having evolved over time. Natural gas has become less sensitive to movements in oil prices, both in the long and short terms, especially after 2011. 

If you look at crude oil and natural gas prices and their correlation, there are some factors that may affect the correlation in this case. These include: 

• Transportation & Storage: It is easier to transport and store crude oil than natural gas, thereby enabling varying market constraints. 
• Economic Aspects: Higher demand for crude oil may increase overall energy demand, thereby spiking natural gas prices. Conversely, it may lead to a supply-driven dip in natural gas if associated gas production increases. 
• Regional Market Dynamics: Correlations in North America sometimes differ from those in Asia or Europe, owing to specific market dynamics and infrastructural factors. 

Why Crude Oil Can Influence Natural Gas Prices

What are the reasons for the crude oil impact on gas prices? Here are some of them: 

• Supply Side (Associated Production): A major chunk of natural gas production occurs as a byproduct of crude oil drilling, particularly in the Permian Basin and other shale formations. When oil prices are on the higher side, drillers produce more, leading to higher associated gas production as well. This supply increase may lead to a fall in natural gas prices, even though oil prices are on the upswing. 
• Demand Side (Interchangeable Usage): Natural gas and oil are substitutes in several sectors, such as power. If crude oil prices rise substantially, consumers may shift to natural gas, leading to a spike in demand and driving up the price of the commodity. 
• Historical Contract Indexing: Natural gas contracts have historically been indexed to crude oil prices. While the correlation has weakened across markets like the US (now it depends mostly on gas-to-gas pricing), it still has a role to play in global markets. Hence, gas prices sometimes follow the oil market trends. 
• Production Costs: Labour, machinery, energy, and other components for oil and gas exploration are often similar in nature. Hence, when oil prices spike, demand for rigs goes up, thereby scaling up operational costs across both industries. This may directly impact prices. 

Demand-Side Factors Linking Crude Oil and Natural Gas

There are several demand-side factors that drive crude oil and natural gas prices and link the two commodities. They include: 

• Industrial Demand and Economic Growth: Worldwide economic growth propels industrial demand for both these energy sources across industries 
• Fuel Substitution: In power generation, several utilities may switch between oil and natural gas based on relative prices. When oil prices are higher, demand shifts to the more affordable and often more available natural gas (and vice versa). 
• Variability in Weather: Cold, seasonal weather conditions increase heating demand for natural gas. This often influences and is also influenced by the sentiments in the general energy market. 
• Regulatory and Geopolitical Aspects: Changes in regulatory and environmental policies, along with carbon taxes, affect demand for both commodities. This may sometimes encourage a shift from oil to cleaner fuel like natural gas. 
• Heating and Transportation: While petroleum is the dominant player in transportation, sectoral fluctuations may affect global energy demand (and both the gas and oil markets). 

These demand-side factors may lead to a positive correlation between the two commodities, especially during structural shifts in the global energy sector or key economic cycles. 

Supply-Side Factors Connecting Oil and Gas

There are various supply-side factors linking crude oil and natural gas as well. Some of them include: 

• Production of Associated Gases: A major chunk of natural gas is basically associated gas produced from oil wells. Hence, higher oil drilling and production often lead to higher natural gas supply, irrespective of its market demand. 
• Shared Services and Input Costs: Both gas and oil production mainly depend on the same services, skilled labour, and equipment, including well completion services and drilling rigs. An increase in oil prices may lead to higher investment and drilling activity, thereby tightening these service markets. It leads to higher costs for both natural production and exploration. 
• Integrated Infrastructure: The midstream segment, i.e., storage facilities, pipelines, and processing plants, is vital for the transportation of both commodities, sometimes within the same networks. Building this infrastructure setup, including LNG terminals, is often driven by top oil companies, thereby linking the supply chains for both commodities. 
• Techniques and Technologies: Technological advancements, such as fracking (fracturing) and horizontal drilling, have completely transformed both sectors. They enable easier extraction of both natural gas and oil from otherwise unconventional resources. 
• Capital and Investments: Oil and gas companies often manage combined portfolios. Hence, downturns in one market may restrict overall capital availability for production and exploration in another. This impacts supply levels for both these resources. 
• Geopolitical and Regulatory Effects: Political moves such as limiting drilling on public land or banning fracking may affect production and exploration across both commodities. This works as a shared constraint on the supply side. 

Crude Oil as a Benchmark for Energy Market Sentiment

Crude oil is the main benchmark for market sentiments in the global energy category. It indicates the balance between demand and supply, inflationary anticipation, and geopolitical risk premiums.

As of early 2026, WTI and Brent prices are often affected by supply surpluses and tensions in the Middle East. These indicate a more cautious market that balances the build-up of potential inventory against geopolitical disruptions. Here are some aspects worth knowing. 

• Brent is often used as the benchmark for waterborne crude over the Atlantic, while WTI serves as the benchmark for the US. Both are vital for price discovery and hedging. 
• Prices indicate whether the market expects a deficit or surplus. Any forecast of oversupply often puts downward pressure on prices, indicating a bearish consumption outlook (relative to production). 
• Sudden increases in crude prices, especially due to tensions in Iran, may indicate heightened market anxiety and the addition of risk premiums. 
• Crude oil prices directly impact inflation, and dips below major psychological thresholds often indicate slower economic growth. Rising prices, on the other hand, indicate or drive inflationary pressure. 
• Energy sector sentiment also comes into play, with the stock prices of oil-producing entities heavily correlated with global benchmarks. Lower prices may lead to better margins for downstream refiners, on the other hand. 

As of February 2026, the average projection for Brent is around $58 per barrel this year, while WTI mostly tracks slightly lower. This indicates a market currently tackling inventory build and volatility (mostly ongoing). 

When Crude Oil and Natural Gas Prices Move Together

When it comes to how crude oil affects natural gas prices in scenarios like extreme weather conditions, major shifts in the energy sector, or other geopolitical events, the answer may surprise you. They usually move together when shared macroeconomic factors are the driving forces.

Geopolitical conflicts and big disruptions usually lead to higher prices for all energy commodities. Sudden and unexpected weather events may simultaneously impact demand for both resources. 

Periods of swift economic growth may simultaneously affect demand for both commodities, while substitutability cannot be ignored. When oil prices are exceedingly high, consumers may shift to using natural gas for utility or industrial requirements. 

When Crude Oil and Natural Gas Prices Decouple

It is important to note that the prices of both commodities also decouple at times. Some of the factors behind it include: 

• Transformation in Shale Gas: Independent, large increases in shale gas production in North America led to gluts in localised supply. However, this did not impact oil markets globally. 
• Regional Disconnects: Natural gas is largely localised across regional hotspots due to infrastructure needs and transportation costs. Oil, however, is a more globally traded commodity. 
• Structural Shifts: Natural gas markets have matured in recent years, moving away from oil-indexed contracts and towards gas-on-gas structures. This has weakened the correlation between the two. 
• Infrastructural Limitations: Lower LNG capacity naturally limits the flow of gas to high-price regions from low-price zones. This prevents price alignment for both commodities. 

Historically, the prices tend to re-couple or align over longer durations (more than 13 years), whenever global energy markets dominate over local aspects. Yet, short-term decoupling may last for around 2-3 years. 

Impact of Crude Oil Prices on Natural Gas Futures

Another important aspect is the correlations among oil and gas futures. Here’s the impact of crude oil on natural gas futures: 

• Natural gas futures have historically seen long-term positive correlations with crude oil prices. This is because they are often co-produced and work as energy substitutes. 
• Higher crude oil prices sometimes enhance oil exploration and production of associated gas. It may lead to a higher natural gas supply and lower prices, even when oil prices are high. 
• If oil prices rise substantially, many users may switch to more affordable natural gas. This may drive demand and prices for natural gas, thereby aligning them with oil market trends. 
• Production technique changes and varying demand drivers have now led to gas prices exhibiting lower sensitivity to oil price shocks. 
• Short-term natural gas futures are heavily influenced by storage levels and heating/cooling (temperature) demand rather than by crude oil prices. This often causes commodities to move in opposite directions. 
• The connection is often more robust in markets where oil is the gas pricing proxy or where both commodities are directly linked through infrastructure. 
• Crude oil is often a barometer of broader economic sentiments. Hence, extreme oil price shocks may also adversely affect sentiment in the natural gas futures market. 

How Traders Use Crude Oil-Natural Gas Correlation

Traders use the correlation between crude oil and natural gas to identify arbitrage opportunities and often to hedge energy portfolios. They also use it to forecast price shifts based on the co-dependency in production. Here’s what they usually do: 

• If the historical and mostly positive correlation breaks down for some reason, traders usually bet that prices will revert to the mean. They buy the underperforming commodity and sell the overperforming commodity as a result. 
• Since both industries share similar types of resources, rising oil prices may increase natural gas production costs and eventually drive up natural gas prices. Traders often look to leverage the same. 
• Traders also capitalise on structural changes in the energy markets, with the two commodities often driven by different fundamentals (geopolitics and weather for oil and gas, respectively). 

Limitations of Using Crude Oil to Predict Natural Gas Prices

Here are the key limitations of using crude oil to forecast natural gas prices. 

• Decoupling & Differences in Key Fundamentals: Since the late 2000s, natural gas prices in the US have moved independently of, or in opposition to, oil prices. Natural gas is mainly driven by fundamentals such as production, storage levels, and weather, rather than by crude prices. 
• Shale Gas Transformation: Higher shale gas extraction has led to an abundant natural gas supply. This has made it trade independently based on domestic supply alone, thereby disrupting the historically tighter links with crude oil. 
• Regional & Global Market Factors: Crude oil is a more global commodity, while natural gas is more regional due to transportation difficulties. Hence, global oil shocks may not always translate directly into local spot prices for natural gas. 
• Seasonal Demand & Weather Patterns: Consumption of natural gas is heavily driven by the temperature (cooling in the summer and heating in the winter). This drives volatility, which is not always seen in the oil prices. 
• Limited Abilities for Substitution: Even though the commodities are power-generating rivals, the ability to switch between them has steadily come down. Hence, an oil price surge does not always lead to a corresponding increase in gas prices or demand. 
• Infrastructural Limitations: Natural gas prices are sometimes driven by the regional takeaway capacity. Bottlenecks in pipelines may lead to sudden price variations that are not linked to crude oil at all. 

Note that there is substantial unexplained natural gas price volatility at shorter horizons, thereby making oil a poor predictor in the short term. Many natural gas contracts in Asia are still linked to oil, while the Henry Hub price is more predominant in North America. Sometimes the relationship is more asymmetric and non-linear, i.e., gas prices may react differently to falling or rising oil prices. 

Conclusion

Natural gas markets are steadily maturing and becoming more independent, especially with the expansion of LNG. Hence, crude oil cannot be used as a primary predictor for its prices anymore across large parts of the globe. This is because local demand and supply factors often drive the natural gas market. Despite a historical positive correlation, the relationship has weakened over time for several reasons outlined above.
