Why investors should watch crude and refined product inventory

Oil and refined product inventory data can move crude oil prices

Every week, the U.S. Energy Information Administration (or EIA) reports figures on crude inventories—the amount of crude oil stored in facilities across the United States. The EIA also provides data on inventories of distillate and gasoline, which are refined products of crude oil.

The markets monitor these figures because inventory data 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 Chevron (CVX), ExxonMobil (XOM), and Hess Corporation (HES)—all of which are major components of energy exchange-traded funds (or ETFs), such as the Energy Select Sector SPDR (XLE) and the Vanguard Energy ETF (VDE).

Another important figure reported by the EIA is the level of crude oil inventories at Cushing, Oklahoma—a major inland oil hub in the U.S. Inventories from Cushing indicate how effectively growing U.S. oil production is moving from major inland production areas such as the Bakken in North Dakota and the Permian in west Texas to end refining markets. A build-up of inventories at Cushing may indicate that oil supplies are growing faster than takeaway infrastructure to end refining markets—many of which are located on the Gulf Coast—can keep up.

Last week, crude oil prices declined marginally after the EIA’s inventory report. Continue reading the next section in this series to learn about declining oil prices.
