A large 3.1 million barrel build in weekly oil inventories has WTI tumbling, down nearly 75 cents and testing $48. Inventories rose as falling demand for oil from refineries offset a sharp decline in oil imports. Total commercial inventories in the October 2 week stood at 461.0 million barrels. Refineries, operating at 87.5 percent of capacity which is comparatively thin, cut back on gasoline production in the week though gasoline stocks rose 1.9 million barrels. But end demand for gasoline, at plus 4.0 percent year-on-year, is strong and points to increased production ahead.
The Energy Information Administration (EIA) provides weekly information on petroleum inventories in the U.S., whether produced here or abroad. The level of inventories helps determine prices for petroleum products.
Petroleum product prices are determined by supply and demand - just like any other good and service. During periods of strong economic growth, one would expect demand to be robust. If inventories are low, this will lead to increases in crude oil prices - or price increases for a wide variety of petroleum products such as gasoline or heating oil. If inventories are high and rising in a period of strong demand, prices may not need to increase at all, or as much. During a period of sluggish economic activity, demand for crude oil may not be as strong. If inventories are rising, this may push down oil prices.
Crude oil is an important commodity in the global market. Prices fluctuate depending on supply and demand conditions in the world. Since oil is such an important part of the economy, it can also help determine the direction of inflation. In the U.S., consumer prices have moderated whenever oil prices have fallen, but have accelerated when oil prices have risen.
