What Is the Second Most Traded Commodity in the World?
Discover the world's second most traded commodity. Understand its global energy impact, market dynamics, and key economic drivers.
Natural gas is the second most traded commodity globally, following crude oil. This energy source plays a significant role in the world’s energy landscape, powering various sectors and influencing international markets.
Understanding Natural Gas
Natural gas is a fossil fuel primarily composed of methane (CH4). It also contains smaller amounts of other hydrocarbons like ethane, propane, and butane, along with non-hydrocarbon gases such as carbon dioxide and nitrogen. A commercial odorant, like mercaptan, is added for safety to detect leaks.
This fuel formed over millions of years from the thermal decomposition of organic matter, such as ancient plants and animals, buried deep underground. Subjected to intense heat and pressure, these organic materials transformed into hydrocarbons, which became trapped in porous rock formations. Natural gas can be found in various geological formations, sometimes alongside crude oil or coal.
Natural gas sources are categorized into conventional and unconventional types. Conventional natural gas is found in highly permeable reservoirs where it flows easily to the surface through traditional drilling. Unconventional sources, like shale gas, tight gas, and coalbed methane, are trapped in less permeable rock formations, requiring advanced extraction techniques such as hydraulic fracturing. Hydraulic fracturing involves injecting water, sand, and chemicals at high pressure to create fractures in the rock, allowing the gas to flow.
Global Significance of Natural Gas
Natural gas is a heavily traded commodity due to its extensive use across numerous sectors worldwide. A significant portion of natural gas is utilized for electricity generation. Natural gas power plants can quickly adjust their output, making them responsive to fluctuations in electricity demand and supportive of grid stability.
Beyond electricity, natural gas serves as a fuel in industrial processes, including the production of fertilizers, chemicals, and manufactured goods. The industrial sector uses it as both an energy source and a raw material. In residential and commercial sectors, natural gas is widely used for heating buildings, cooking, and powering appliances.
Natural gas also plays a role in transportation, primarily as Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG). While it constitutes a smaller portion of transportation fuel, CNG is suitable for light-duty and low-mileage vehicles, while LNG, being denser, is preferred for heavy-duty and long-haul applications. It produces fewer carbon emissions and pollutants compared to coal and oil when burned, contributing to efforts to reduce greenhouse gas emissions.
How Natural Gas is Traded
The global natural gas market involves sophisticated mechanisms for buying and selling. Futures contracts are a primary tool, allowing market participants to lock in prices for future delivery. These contracts are traded on exchanges linked to major trading hubs worldwide.
Key trading hubs facilitate these transactions, such as Henry Hub in the United States, a significant benchmark for North American natural gas prices. In Europe, the Title Transfer Facility (TTF) serves as a prominent virtual trading point, while the Japan Korea Marker (JKM) is a crucial benchmark for Asian spot LNG prices. These hubs provide transparent pricing signals that reflect regional supply and demand dynamics.
International transport of natural gas occurs through two main methods: extensive pipeline networks and Liquefied Natural Gas (LNG) tankers. Pipelines are used for regional and continental distribution, connecting producing regions to consumption centers. For intercontinental trade, natural gas is super-cooled to approximately -260°F (-162°C) to become LNG, which significantly reduces its volume and allows for transport by specialized tankers across oceans. This liquefaction process has globalized the natural gas market, enabling countries without pipeline access to import natural gas and increasing market liquidity.
Key Factors Influencing Natural Gas Markets
Natural gas markets are influenced by a combination of supply and demand factors, along with broader economic and geopolitical developments. On the supply side, production levels, new discoveries, and the development of infrastructure like pipelines and LNG terminals directly impact availability. Geopolitical events and stability in major producing regions can disrupt supply chains, leading to price volatility.
Demand-side factors are heavily influenced by seasonal weather patterns, particularly for heating in winter and cooling for electricity generation in summer. Economic growth and industrial activity also drive demand, as industries require natural gas for energy and as a feedstock. Policy shifts towards cleaner energy or increased reliance on natural gas for power generation also affect demand patterns.
Storage levels play a significant role in balancing natural gas supply and demand, particularly due to seasonal fluctuations. Gas is typically injected into storage facilities during periods of lower demand and withdrawn during peak consumption, such as cold winters or hot summers. High storage levels can indicate ample supply, potentially leading to lower prices, while low storage levels can signal scarcity and contribute to higher prices and market volatility.
