What happened
US API crude oil throughput for the week ending September 18 registered -527,000 barrels per day, according to data cited by Jinshi Data.
The prior week's reading was -115,000 barrels per day.
Why it matters
The API figure offers an early read on refinery crude demand in the United States, and the wider negative swing suggests a sharper pullback in throughput than in the previous week.
Because the API data is a weekly industry estimate, it is often treated as a precursor to official inventory and processing figures, so the larger decline may shape near-term expectations for the crude market.
