The EIA reported that total U.S. propane/propylene inventories decreased by 2.1 MMbbl for the week ended August 28, compared with an industry-expected build of 1.4 MMbbl and the average build of 2.2 MMbbl for the week. The counterseasonal draw lowered stocks to 107.4 MMbbl (red line in the chart below). Despite the decline, stocks are 11.2 MMbbl, or 12%, above both the same week in 2025 (blue line) and the five-year maximum and 21.2 MMbbl, or 25%, above the five-year average (green line). Purity propane inventories accounted for much of the decline, falling by 1.3 MMbbl to 74.6 MMbbl, representing 69% of total U.S. inventories and remaining 25% above the same week in 2025. PADD 3 (Gulf Coast) accounted for roughly two-thirds of the nationwide draw, with regional inventories declining by 1.4 MMbbl.
Exports and Product Supplied
Weekly propane exports reported by the EIA increased by 135 Mb/d to 2.15 MMb/d (red line in the first chart below). Exports were 104 Mb/d, or 5%, above the four-week average (dashed green line) and 366 Mb/d, or 20%, above the same week in 2025 (blue line). Volumes were also 8% above the year-to-date average of 1.99 MMb/d. Meanwhile, product supplied rose sharply by 494 Mb/d to 1.13 MMb/d (red line in the second chart below). Together, exports and product supplied increased by 629 Mb/d, or 24%, from the previous week, providing additional context for the counterseasonal inventory draw.
