While there are concerns over slumping US gasoline demand, February's 16.0% gain in auto sales might suggest otherwise. April RBOB prices have taken a slightly lower track this morning as they correct yesterday's surge to a new contract high. The gasoline market seemed to draft a level of support during the mid-session following inventory reports out of the Amsterdam-Rotterdam-Antwerp storage hub that showed gasoline stocks falling nearly 5% on the week. This seemed to provide further evidence of a tighter European gasoline market.
