November RBOB prices traded higher during the initial morning hours, helped by an improvement in risk taking attitudes and private industry data, that was released after the close yesterday, that showed a surprisingly large gasoline inventory decline. Market expectations for this morning's EIA report are for a build in US gasoline stocks in the range of 250,000 to 500,000 barrels. US west coast cash gasoline prices seemed to reflect a modest amount of tightening yesterday on reports that a couple of California refineries were being taken down for planned work.
