EIA Report Shows Unexpected Inventory Changes
Before this report, WTI crude oil was trading up by 68 cents, priced at $63.32. Private data released the previous day showed an increase in crude oil inventories by 1250K barrels. Additionally, gasoline stocks rose by 329K barrels, and distillates increased by 1500K barrels.
The weekly inventory numbers for September 5th were surprisingly bearish, showing a large build in crude oil when a draw was expected. We saw crude stocks increase by nearly 4 million barrels against expectations of a 1 million barrel decline. This suggests a significant and sudden drop in demand or a surge in supply that the market did not anticipate.
These figures align with recent economic data indicating a global slowdown, which dampens the outlook for fuel consumption. For instance, China’s manufacturing PMI for August 2025 came in at 49.2, marking the second consecutive month of contraction and signaling weaker industrial demand. The massive 4.7 million barrel build in distillates, used for diesel and heating oil, directly reflects this industrial weakness.
Price Implications and Trading Strategies
Historically, we’ve seen similar patterns precede significant price drops, such as the inventory builds in late 2018 which were followed by a 40% fall in WTI crude prices over that quarter. The current situation, occurring just as the peak summer driving season ends, indicates this may be more than just seasonal softness. This suggests the recent price of $63.32 per barrel is likely unsustainable in the short term.
For derivative traders, this environment strongly favors establishing bearish positions. We believe buying out-of-the-money put options on WTI for October or November expiration is a prudent strategy. This allows for capitalizing on potential downside movement towards the $55-$60 range while strictly defining the maximum risk on the trade.
Traders using futures should consider shorting the front-month contract, but must use disciplined stop-loss orders to manage the risk of a sudden reversal from geopolitical news. The report is also likely to push the futures curve further into contango, making bearish calendar spreads an attractive play. This involves selling the front-month contract and buying a deferred contract to profit from the widening price difference.
