September crude oil prices traded higher during the overnight and initial morning hours as they corrected a portion of yesterday's decline. Some of the early support this morning comes from a rebound in risk-taking sentiment, gains in global equity markets and weakness in the US dollar. The outside market tone appears to be re-thinking yesterday's ECB decision that fell short of expectations for bold action, and that has offered a measure of support to the crude oil market this morning. Other supportive forces working in the crude oil market include ideas that an active flow of maintenance in the North Sea region could tighten up supply, at the same time that violence in Syria becomes more severe and as oil producers in Iraq's Kurdistan region look for past-payments.
