Why crude tumbled on rising inventories, negative for oil stocks
Oil inventory figures reflect supply and demand dynamics and affect prices
Every week, the U.S. Department of Energy (DOE) reports figures on crude inventories, or the amount of crude oil stored in facilities across the United States. Market participants pay attention to these figures, as they can indicate supply and demand trends. If the increase in crude inventories is more than expected, it implies either greater supply or weaker demand and is bearish for crude oil prices. If the increase in crude inventories is less than expected, it implies either weaker supply or greater demand and is bullish for crude oil prices. Crude oil prices highly affect earnings for major oil producers such as Oasis Petroleum (OAS), Hess Corp. (HES), Chevron (CVX), and Exxon Mobil (XOM).

Another larger-than-expected inventory build sent prices downward again
On October 30, the DOE reported an increase in crude inventories of 4.1 million barrels. In contrast, analysts actually expected a crude oil inventory build of 2.0 million barrels. The larger-than-expected increase in inventories was a negative signal for oil prices. Plus, the prior week was also characterized by a much-larger-than-expected build in inventories, with crude stocks soaring 5.2 million barrels compared to expectations of 2.9 million barrels.
WTI crude prices dropped on the day, closing at $96.77 per barrel in comparison to $98.20 per barrel. Since last Wednesday, oil prices have continued to slide. They currently trade around $95 per barrel—the lowest level for WTI crude since June.
Background: U.S. crude oil production has pushed up inventories over the past few years
From a longer-term perspective, crude inventories had been much higher than where they were in the past five years at the same point in the year (though they’ve closed in under comparable 2012 levels for a period earlier this year). There has been a surge in U.S. crude oil production over the past several years. Inventories had accrued because much of the excess refinery and takeaway capacity had been soaked up, and it took time and capital for more to come online. This caused the spread between WTI Cushing (the benchmark U.S. crude, which represents light sweet crude priced at the storage hub of Cushing, Oklahoma) and Brent crude (the benchmark international crude, which represents light sweet crude priced in the North Sea) to blow out.
However, over the course of 2013, this closed in considerably, so that the two benchmarks traded almost in line again, as more takeaway capacity from the Cushing hub came online. Recently, however, the spread has widened back out (see Why the WTI-Brent oil spread is at its widest level since March for more analysis).
This week’s larger-than-expected build in U.S. inventories was a negative short-term indicator for WTI crude prices
WTI price movements and broader oil price movements affect producers of crude oil, as higher prices result in higher margins and earnings. Names with portfolios slanted towards oil such as Oasis Petroleum (OAS), Hess Corp. (HES), Chevron Corp. (CVX), and Exxon Mobil (XOM) could see margins squeezed in a lower oil price environment. Plus, oil price movements affect energy sector ETFs such as the Energy Select Sector SPDR Fund (XLE), an ETF that includes companies that develop and produce hydrocarbons as well as the companies that service them.
