The weekly change in U.S. ending stocks of total gasoline (EIA series WGTSTUS1), shown in million barrels.
Full explanation
EIA Gasoline Stocks Change measures the weekly change in U.S. ending stocks of total gasoline (EIA series WGTSTUS1), which covers finished motor gasoline and motor gasoline blending components. It is published in the Energy Information Administration's Weekly Petroleum Status Report. EIA reports the stock level in thousand barrels; calendars show the week-on-week change in million barrels, where a positive number is a build and a negative number is a draw. Traders use it as a timely read on U.S. refined-product supply and demand.
Why traders watch it
Gasoline inventory changes can move refined-product prices, crude oil futures and energy-sensitive inflation expectations. Because oil prices affect risk sentiment, inflation breakevens and some currency flows, the release can also matter for USD, rates and commodity-linked assets.
Market interpretation
- Gasoline and refined-products futures
- Inventory surprises can affect expectations for product tightness and refining margins.
- Crude oil
- Gasoline data can influence crude prices by changing expectations for refinery demand and product-market strength.
- U.S. dollar and rates
- Energy-price moves may affect inflation expectations and short-term macro sentiment, with indirect implications for USD and rates.
- Equities
- Energy producers, refiners, airlines and transport shares can be sensitive to changes in fuel-price expectations.
Stronger vs weaker outcomes
A larger-than-expected build may suggest softer gasoline demand or ample supply and could weigh on gasoline and crude prices, while a larger-than-expected draw may suggest tighter product supply or stronger demand and could support energy prices. The market reaction often depends on the companion crude oil, distillate, refinery utilization and implied demand figures.
A higher-than-expected reading usually means a larger inventory build or a smaller draw than expected, which may signal looser gasoline supply or softer demand.
A lower-than-expected reading usually means a smaller build or a larger draw than expected, which may signal tighter gasoline supply or stronger demand.
For this release, the surprise is interpreted as an inventory build or draw relative to expectations rather than as a simple good-or-bad economic outcome.
Release details
- Release frequency
- Weekly
Typical volatility
High. Weekly petroleum data can be volatile and affected by refinery outages, imports, exports, weather, holidays and reporting revisions. A single inventory change should be interpreted alongside broader seasonal patterns and the full Weekly Petroleum Status Report.
Trading considerations
- Compare gasoline stocks with crude oil stocks, distillate stocks and refinery utilization before drawing conclusions.
- Account for seasonal demand patterns, especially the U.S. summer driving season and holiday weeks.
- Watch whether the move is concentrated in a specific PADD region or visible across the national data.
- Be aware that spreads can widen around the release and that futures markets may react within seconds.
