June crude oil prices were under modest pressure during the early morning hours, seemingly in sympathy with plunging Brent crude oil and private industry data that showed a larger than expected US inventory build. The outside market tone was also under pressure, with weakness in European and US equities and gains in the US dollar. Some traders indicated that the shift in flows in the Seaway Pipeline continued to weigh on Brent crude oil and has fostered active liquidation out of the long Brent vs. WTI crude oil spread. Expectations for this morning's EIA report are for a build in the range of 1.0 million barrels, which compares to the five-year average draw of 400,000.
