May RBOB prices came under selling pressure during the early morning action, hamstrung by a sell off in global equity markets, gains in the US dollar and weakness in the crude oil market. The early slide in RBOB prices virtually reversed yesterday's late day gain of more than $0.05. It seems that the demand picture for the US gasoline market has taken a negative turn after weak US jobs report late last week, and that is a force that could gain more traction as the impact of record prices is revealed.
