US crude oil inventory data
In the week ending March 23, 2018, US crude oil inventories rose by 1.64 MMbbls (million barrels) to ~429.94 MMbbls. The market expected a rise of 0.5 MMbbls in the EIA’s data on March 28, 2018. On the same day, US crude oil May futures fell 1.3%.
In the week ending March 23, 2018, US crude oil inventories were 1.5% less than their five-year average—a bullish factor for oil prices. The difference is called the “inventories spread.” Oil prices and the inventories spread usually move inversely. The above graph illustrates this relationship. In the week ending March 16, 2018, the inventories spread was at -0.9%.

Inventory data could drag oil prices
In the week ending March 30, 2018, the fall in US crude oil inventories should be more than 273,000 barrels for the inventories spread to expand more into the negative zone. However, the market expects a rise of 1.667 MMbbls in the EIA data to be released on April 4, 2018, which could mean more bearish pressure on oil prices.
