WTI Crude oil got hit hard, yesterday, as sentiment around the one-way trade of a narrowing Brent-WTI spread got up-ended by a snag in the foundation of the trade, the Seaway pipeline. The company announced a reduction in flows by half. The reason was not very clear, but the reaction was swift: the spread widened by almost $2.00 per barrel. WTI futures fell about $1.50.
