Butane’s Perfect Storm Sends Prices to Decade Highs

Butane is a hydrocarbon component of liquefied petroleum gas, or LPG. LPG supplies cooking fuel and also serves industrial and refining needs. Butane matters because its vapour pressure helps the fuel vaporise properly. In warmer climates, that makes it especially useful in household cooking-gas blends.

The article says Indian and many other Asian markets usually favour an LPG blend close to 50:50 propane and butane. But US LPG exports contain about 75% propane and only 25% butane. Therefore, replacing Middle Eastern LPG with more American cargoes can leave Asian buyers short of the component their consumers need.

That imbalance is helping drive butane prices higher. Asian buyers are competing for limited butane while US refiners also need it for winter gasoline. The result is tighter availability for Europe and unusually high prices across all three major regions.

Butane prices have reached exceptional levels in all three major markets. Northwest European November prices hit $1,125 per tonne by early November. Asia’s AFEI butane index stood at $1,180 per tonne on November 3. US Belvieu prices reached $920 per tonne.

These levels are unusual, not merely routine seasonal increases. Northwest European prices are at their highest point in 30 years, even exceeding peaks recorded after Russia’s invasion of Ukraine. US prices are at a 14-year high. Asian prices are the highest among the three figures reported.

The surge reflects several pressures arriving together. Asia needs replacement cargoes after Gulf supply fell. China’s industrial growth is increasing imports, while India needs suitable cooking-gas blends. At the same time, winter gasoline demand is rising in the Atlantic basin, tightening competition for butane.

The conflict radically redirected global LPG trade. Before the US-Iran war began in March, the US supplied roughly 45–50% of global LPG exports, while the Middle East supplied another 30–35%. After the crisis began, Gulf shipments fell sharply.

The Gulf countries’ share subsequently collapsed to 11%. The US stepped in and increased its share to 65%, replacing much of the shortfall. Asia absorbed a large portion of those American cargoes because Middle Eastern producers had previously supplied about half of Asian imports.

Gulf deliveries from the UAE, Kuwait, Qatar and Saudi Arabia gradually recovered, reducing the US share of Asian imports to around 55% in October. However, the restoration has been stronger for oil than LPG. American cargoes remain essential in Asia, pulling supplies away from Europe, where October butane imports into the ARA hub fell 34% year on year.

Asia is competing strongly because Middle Eastern LPG shipments fell, while regional demand stayed high. Middle Eastern producers had supplied about half of Asia’s imports, with short voyages and cargoes suited to local needs. American cargoes are now filling much of that gap, despite their less suitable propane-to-butane mix.

India was especially exposed: about 87% of its LPG imports came from the Gulf, with the UAE and Qatar together providing half. Its imports fell from 2.03 million tonnes in February to 1.17 million tonnes in March. China’s demand is also growing as new MTBE plants use butane as a feedstock. Five plants opened in 2025, adding 3.4 million tonnes per year of capacity.

China can export the resulting gasoline additive, so overseas demand supports its butane purchases even when Chinese gasoline use is weak. India’s recovering imports and US supplies have also helped refiners reduce emergency LPG production and restore petrochemical output.

The problem is not simply the total amount of LPG available. It is the composition of that LPG. Asian cooking-gas markets, including India, commonly favour blends close to 50% propane and 50% butane. Both components are needed to meet local fuel requirements.

US exports are approximately 75% propane and 25% butane in outright terms. Middle Eastern supplies contained more of the butane that Asian buyers require. Sending extra American propane can therefore replace only part of the lost supply. It cannot fully reproduce the original blend, especially where butane helps maintain suitable vapour pressure in warm climates.

This mismatch keeps pressure on the global butane market. Asia must compete for additional butane cargoes even while receiving large US LPG volumes. The shortage also reduces supplies available to Europe, where refiners are increasing butane use for winter gasoline.

The seasonal switch to winter-quality gasoline increases butane demand in the United States and Europe. Winter fuel specifications require refiners to blend in more butane. Its high vapour pressure helps gasoline vaporise and helps engines start in cold conditions.

The change usually strengthens demand between October and March. That timing matters because US producers must serve domestic refiners just as Asian buyers are seeking replacement cargoes. US exports therefore decline as more butane is needed inside the Atlantic basin.

US exports fell from a record 2.4 million tonnes in May to 1.55 million tonnes in October, although October remained 12% above the previous year. Asia received 840,000 tonnes, or 54% of October shipments, while Europe received only 105,000 tonnes. Seasonal demand is thus tightening an already disrupted market.

Sending American butane to Asia depends on whether the Asian selling price covers the US purchase price and transport costs. The article shows that Asian prices are high, but US winter demand and reduced exports are also pushing American prices upward. That narrows the incentive to move cargoes across the Pacific.

Trade could become more attractive if Gulf LPG exports recovered further, freeing American cargoes for other destinations. Lower US butane prices would also help. So would cheaper freight, while higher Asian prices would increase the return from selling there. These are economic conditions rather than figures supplied by the article.

For now, Gulf LPG recovery remains insufficient to loosen Asia’s reliance on American cargoes. US exports are seasonally declining, while Asian demand and European winter blending demand are strengthening. A wider price gap or lower transport costs would be needed to redirect more US butane toward Asia.
