API: U.S. Crude Oil Inventories Plunge by 11.1 Million Barrels in a Single Week
nashnova research
API data show U.S. commercial crude stocks fell 11.1 million barrels in a single week, far exceeding expectations and marking the largest recent weekly draw; the EIA's official report will determine whether oil prices follow through.
How big is an 11.1-million-barrel draw?
In the week ending October 9, U.S. commercial crude inventories dropped 11.1 million barrels; the prior week's draw was just over 2 million barrels.
This means → the pace of destocking accelerated roughly fivefold in a single week — an extreme outlier.
In plain terms = crude vanished from storage at a suddenly much faster rate, and the market had not priced anything close to this.
Why was the market caught off guard?
Consensus had expected a modest drawdown; the actual figure blew past that estimate.
This means → either demand spiked temporarily or supply tightened on the margin — the exact driver needs the EIA report to confirm.
Gasoline inventories also shifted during the same week, but API has not fully disclosed the figures, so a parallel draw cannot yet be confirmed.
What is the difference between API and EIA data?
API (American Petroleum Institute) figures are an industry-compiled estimate, typically released ahead of the EIA (Energy Information Administration) official weekly report.
In plain terms = API is the trailer; EIA is the feature film — the market ultimately prices off EIA numbers.
This reflects a broader pattern: a large API draw is only the first signal. If EIA confirms it, oil prices may find further support; if EIA falls short, the market reaction is likely to reverse quickly.
