WTI Order Imbalances Before EIA Oil Inventory Announcements
Summary
The study examines whether WTI crude futures trading before weekly US Energy Information Administration inventory releases is consistent with informed trading. It compares announcement outcomes with analyst expectations and analyzes intraday prices and buyer- versus seller-initiated order imbalances around the release. The reported pattern is strongest when inventories exceed expectations: selling pressure and price moves appear before the announcement, while the market response is asymmetric and some of the initial move reverses over the following hours. The authors also describe robustness checks using alternative definitions of an unexpected inventory result.
The evidence is suggestive rather than conclusive. Order imbalance can indicate trading on information, but the authors cannot identify how any private information reached traders; skilled forecasting or interpretation of ongoing supply-demand information could produce similar patterns. The work therefore raises questions about market information security and monitoring, rather than proving illegal insider activity or establishing a profitable trading rule. Its findings concern a specific historical sample, contract, and scheduled announcement setting, and should not be assumed to generalize to other commodities or periods.
Key ideas
- The study uses intraday WTI futures order imbalance to investigate trading before weekly EIA inventory releases.
- Selling pressure before the announcement is associated with inventory increases that exceed analyst expectations.
- The price response is asymmetric, and part of the initial move is reported to reverse after the news.
- Order imbalance is consistent with informed trading but does not establish that traders used leaked information.
- The results motivate monitoring around scheduled releases but do not demonstrate a profitable strategy.
