Brent slipped below $104/B on Thursday as investors remained worried about fuel demand after a series of weak economic data although losses were capped by hopes for more US stimulus measures to support growth. Prices also fell after US government data showed an unexpected rise in domestic crude stockpiles last week, stoking oil demand worries (Reuters). Brent crude fell 52 cents to $103.86/B, while US crude was down 48 cents at $88.49/B.
