Global LPG Conversations: US Butane Flows Surge to Meet Asia’s Demand
Why It Matters
The shift of Asian LPG demand to U.S. supplies reshapes global energy trade, affecting pricing and supply security for countries like India and Japan. Understanding these dynamics helps market participants and policymakers anticipate price trends and infrastructure needs as the U.S. becomes a key butane source amid geopolitical tensions.
Key Takeaways
- •Mid-March butane price hit $1,200/tonne, record high.
- •U.S. produces ~75 tons/day butane, mainly for export.
- •Energy Transfers Nederland handles 36% of U.S. butane exports.
- •New capacity adds 300k bpd at Enterprise Houston terminal.
- •Split propane‑butane cargo premiums fell to $0.09/gallon.
Pulse Analysis
The Iran‑related war sparked a sharp surge in global butane prices, pushing the August Far East Index to roughly $1,200 per tonne in mid‑March. Asian markets that traditionally relied on mixed propane‑butane cargoes from the Middle East suddenly faced tight supplies, driving Japanese spot prices to multi‑year highs. This volatility highlighted the United States’ role as the largest alternative LPG source, prompting a rapid increase in U.S. butane exports to meet Asian demand.
U.S. butane production stems largely from shale‑gas processing, delivering about 75 tons per day—roughly 9.5% of total NGL output. The bulk of this volume is funneled through major Gulf Coast terminals such as Energy Transfers’ Nederland facility (accounting for 36% of U.S. butane shipments), Enterprise’s Houston hub, and Phillips 66’s Freeport site. New midstream projects are expanding capacity: Enterprise plans a 300,000 bpd LPG loading boost by year‑end, while Targa adds 150,000 bpd in 2027 and Canada’s AltaGas prepares a 55,000 bpd Ridley Island export terminal.
Domestically, tightness lifted Mont Bellevue butane prices to a three‑year peak of $634 per ton (about $0.14 per gallon) in May, before a recent dip aligned with falling WTI crude. Terminal fees, a key component of FOB pricing, surged to over $0.50 per gallon for split propane‑butane VLGC loads during the crisis, but have since receded to roughly $0.09 per gallon as export volumes normalize. The market now appears to be settling into regular split‑cargo patterns, balancing Asian demand with U.S. supply while keeping price premiums modest.
Episode Description
Why US butane is in high demand across Asia and what growing export volumes mean for prices, trade flows and infrastructure plans.
The war in Iran and the Strait of Hormuz blockade have shaken LPG trade flows, sending delivered butane prices in Asia to multi-year highs and leaving buyers racing to secure alternative supply. US producers and exporters are stepping in fast—but can export capacity and logistics keep up with this unprecedented demand?
Host Anu Agarwal (Vice President, Business Development, Argus Oil in Asia) is joined by Amy Strahan (Editor, LPG North America) to examine how Gulf Coast terminals and Mont Belvieu storage are operating at full capacity to keep cargoes moving, and why looming bottlenecks could reshape prices and trade flows in the months ahead.
