The EIA reported a 1.4-MMbbl decrease in total U.S. propane/propylene inventories for the week ended September 11, compared with an industry-expected build of 650 Mbbl and an average build of 1.0 MMbbl for the week. The counterseasonal draw—the largest for the comparable week in our records dating back to 2011—lowered stocks to 109.1 MMbbl (red line in the chart below). Despite the decline, inventories are 10.2 MMbbl, or 10%, above the same week in 2025; 8.4 MMbbl, or 8%, above the five-year maximum; and 18.9 MMbbl, or 21%, above the five-year average.
