US Petroleum stocks remained unchanged – May 19

In the recent Energy Information Administration petroleum report there is an analysis of the reasons behind the high gasoline prices which includes not only the high crude oil prices, but also domestic concerns that drove gasoline prices up; these concerns include the unplanned refinery outages and concerns over flooding of the Mississippi River that might impact refinery productions. These factors are among the major reasons for the current high gasoline prices in the US, according to the report.

That being said, EIA analysts are optimistic and think that the worst is over and estimate that, all things begin equal, gasoline prices should start to come down in the weeks to come.

Here is a weekly review of the EIA petroleum report regarding crude oil price and petroleum stocks for the week ending May 13th:
