U.S. LPG Exports Down Again In January 2025

Five years ago, the U.S. was a net importer of propane and butanes, those products collectively called LPG, or liquefied petroleum gasses. Back then, demand from residential, commercial, refining and chemical markets slightly exceeded supply for the products. But then came shale, and LPG production from natural gas processing more than doubled, from 0.8 Mb/d to 1.7 Mb/d. Suddenly the U.S. was a net exporter—a very big exporter at that. Last year roughly half of all LPG from U.S. gas processing plants was exported, with the vast majority shipped to overseas markets. All those exports are now having an outsized impact on pipeline flows, inventories and prices. Consequently, it is increasingly important to keep close tabs not only on export volumes but on which export terminals are handling all these volumes, and where the LPG is heading. Today we discuss the current state of the LPG export market and insights on it from RBN’s most recent NGL Voyager Report. Warning, today’s blog includes a subliminal promo for the report.

The EIA report on propane inventories that came out yesterday was a shocker. This time of year, stocks are supposed to be building toward the levels needed to get U.S. propane markets through the winter season. But the numbers released on Wednesday showed an inventory decline, resulting in inventory balances now below the five-year minimum. The culprit, of course, is exports, with 1.4 MMb/d of them reported last week, a 17% gain over the year-to-date average. And these cargoes to overseas markets are happening even with propane prices in the stratosphere: more than double where they stood this time last year. Propane marketers were hoping that higher prices would slow down exports, but so far that is not happening. In today’s blog, we examine U.S. exports of LPG — propane plus butane — and discuss what may be ahead for these markets.

Since 2011, U.S. natural gas liquids (NGL) production has more than tripled, while domestic demand has grown only modestly. Consequently, the only way NGL markets could balance was a dramatic increase in exports. Today, over 70% of U.S. propane production is exported, with the majority going to overseas markets, while other NGLs see varying export levels: 40% for butanes, 25% for natural gasoline, and 18% for ethane. Although U.S. NGL production growth is slowing, we still project an increase of 1.5 MMb/d over the next decade and a half, with 85% of that growth coming from the Permian Basin. As U.S. ethane and LPG production continues to rise, nearly all the export growth is expected to head to the Asia/Pacific region, with a significant portion going to one country: China. But is this outlook for U.S. NGLs realistic? And do we have adequate infrastructure — ranging from gathering systems to processing plants and fractionators, and from export terminals to the right kind of ships — to handle all of these volumes? In one of his hit tunes, Toby Keith clearly identified the problem for us: “Where You Gonna Go? And What Ya Gonna Do When You Get There?” These are key NGL market themes that we'll be exploring at our upcoming NACON conference on October 24 at the Royal Sonesta Hotel in Houston and that we’ll introduce in today’s RBN blog.
