This is a real bugbear for me and I assume everyone else. Recent upheavals in the Middle East have already pushed up the price of a barrel of oil. Doubtless we will quickly see a rise at the pumps within a few days/weeks. But I wonder how this rise in the price of oil so rapidly impacts on pump prices ? Assuming that the oil currently in Ireland or on it's way to Ireland as we speak, was bought at the lower prices how is it possible that fuel prices at the pumps is raised so quickly? Oil also requires refinement before sale, so presumably all fuel we will use for the next few months or so was bought at the lower price, how can higher prices be justified now or in the near future? The whole system seems potentially open to abuse. Does anyone in gov.t or at EU level oversee this ?
