US crude inventories jumped by nearly 3 million barrels last week when analysts expected a draw.
What happened
The US added 2.969 million barrels of crude oil to storage versus estimates of a 0.700 million barrel draw. The surprise sent oil prices falling, extending a drop that now totals 10.3 percent over the past week.
Why it matters
A build when the market expected a draw signals either more supply or slower refining demand than anticipated. The move rippled through roughly 500 billion dollars of market value tied to energy, with the broad market slipping even as US futures remained up 3.3 percent on the week.
The case against
One weekly data point does not erase the structural tightness in global energy markets. Gulf flow risks and Western demand for non Russian molecules, along with US producers exercising supply discipline, still support elevated crude prices for years.
What settles it
Next week's EIA inventory report to see if the builds persist or reverse.
