Oil Inventory FAQ
Commercial crude oil inventories are stocks held by private companies (refineries, traders, etc.) for business purposes. This excludes the Strategic Petroleum Reserve, which is government-owned. Commercial stocks directly influence crude oil prices as they indicate supply/demand balance.
The EIA releases the Weekly Petroleum Status Report every Wednesday at 10:30 AM Eastern Time. This report includes commercial inventory levels, SPR stocks, and refinery inputs.
A draw means inventories fell over the report week (more crude was consumed or exported than added), and a build means they rose. Traders watch draws and builds because they signal whether supply is tightening or loosening: a larger-than-expected draw is typically bullish for crude prices, and a larger-than-expected build is typically bearish. The figures come from the EIA Weekly Petroleum Status Report (WPSR).
Confirm the inventory API contract and account access before integrating. This page shows available inventory observations and week-over-week changes; its website data feed is not a stable customer API contract. The series follows the EIA WPSR publication schedule (released Wednesdays, 10:30 AM Eastern), so values appear once the EIA publishes them rather than in real time.
Days of supply measures how long current inventory would last at current refinery consumption rates. Higher days of supply indicates ample stocks; lower indicates tighter markets. The US typically maintains 25-35 days of crude supply.
PADD 3 (Gulf Coast) holds the largest share of US commercial crude inventories due to its concentration of refineries. Cushing, Oklahoma serves as the key hub for WTI crude delivery, making its storage levels particularly market-moving.
