Natural Gas Pipelines and Supply Leverage

Unlike oil, which can be shipped relatively flexibly by tanker to whichever buyer offers the best price, natural gas has historically depended far more on fixed pipeline infrastructure that physically locks producer and consumer together for decades, since building a pipeline commits enormous capital to a single route and, often, a single set of counterparties. This structural feature transforms gas trade into a strategic relationship rather than a purely commercial one: a supplier can credibly threaten to cut off gas because the buyer has no easy alternative source in the short term, and a buyer that depends on one pipeline route acquires a corresponding vulnerability. The rise of liquefied natural gas (LNG), which cools gas to about -162°C for transport by specialized tanker, has begun eroding this rigidity since the 2000s by allowing gas to be shipped globally like oil, with the United States, Qatar, and Australia emerging as leading LNG exporters and Asian and European buyers gaining new flexibility to switch suppliers.
