Crude oil inventories in Cushing, Oklahoma, are down more than 40% from start of 2021

Why The Cushing Storage Hub Matters To Oil -


Crude oil inventories in Cushing, Oklahoma, totaled 32.9 million barrels (excluding pipeline fill and stocks in transit by water and rail) in the week ending September 10, which is a 42% decrease since the beginning of the year reports the U.S. Energy Information Administration.

Crude oil inventories at Cushing are now 26% lower than normal, based on the previous five-year (2016–2020) average for that time of year.

The Cushing storage hub is the crude oil delivery point for the NYMEX West Texas Intermediate (WTI) crude oil futures contract and is home to 14% of U.S. commercial tank and underground crude oil working storage capacity.

The storage withdrawals in Cushing are consistent with high crude oil inventory withdrawals elsewhere in the United States and globally in recent months. According to the EIA’s latest Petroleum Supply Monthly, the decline of 35 million barrels (the equivalent of 1.2 million barrels per day) in June 2021 was the largest decline in U.S. crude oil inventory (including crude oil held in the Strategic Petroleum Reserve) since it began collecting this data in 1981. In general, inventories tend to decline when consumption exceeds production.

The 32.9 million barrels of crude oil in inventory on September 10 means Cushing had a storage capacity utilization of 43%. Before this year’s decline in inventories, the most recent time that Cushing storage utilization had fallen that low was in late 2018, following disruptions on the Keystone Pipeline system (which extends from Canada through Cushing to export terminals on the Texas Gulf Coast) and after the Diamond Pipeline system (which runs from Cushing to Memphis, Tennessee) entered service.

Since April 2020, the EIA has published U.S. crude oil inventory as a percentage of working U.S. storage capacity to calculate storage capacity utilization. To estimate current working storage capacity utilization, the agency compares weekly reported crude oil inventories with the latest available monthly refinery and tank farm storage capacity. The reported crude oil inventories exclude pipeline fill and estimated barrels in transit by tanker ship, barge, rail, or truck. These exclusions total 2.5 million barrels at Cushing in the latest EIA estimate.
