The EIA reported a build of 2 MMbbl in total U.S. propane/propylene inventories for the week ended August 14, exceeding industry expectations for a build of 860 Mbbl and the average build of 1.6 MMbbl for the week. The increase lifted total U.S. stocks to an all-time high of 107 MMbbl (red line in Figure 1 below). Inventories are now 15.8 MMbbl, or 17%, above the same week in 2025 (blue line); 14.7 MMbbl, or 16%, above the previous five-year maximum; and 24.9 MMbbl, or 30%, above the five-year average (green line). Total stocks could approach 117 MMbbl by early October if inventories follow the average seasonal building pattern of recent years before draws begin.
