March RBOB prices trended higher during the initial morning hours and appeared to be the upside leader within the crude oil complex. Early gains in March RBOB during yesterday's session came from a rally in European gasoline prices to fresh 28-month highs. Some traders also pointed to positive US economic data as another factor that bolstered hopes for increased gasoline demand. Meanwhile, cash markets in the Gulf and west coast regions garnered a measure of support on reports of a refinery in Texas that neared closure due to the freezing temperatures.
