September RBOB prices traded higher during the initial morning hours, boosted by a positive outside market tone and private industry data Tuesday that showed a unexpectedly large decline in US gasoline supplies. Expectations for this morning's EIA report call for a draw in the range of 1.0 million barrels. Some traders appeared to be more concerned with gasoline demand. While last week's EIA data showed a surprise increase in gasoline demand to 9.244 million barrels per day, traders wonder if it was an anomaly or the start of a new trend.
