KONTAN.CO.ID - LONDON. Oil slipped from seven-month highs on Thursday as signs of growing supplies helped to halt a rally driven by optimism that vaccines will revive fuel demand.

Brent futures had risen to nearly $50 a barrel this week after three major pharmaceutical companies announced progress on vaccines that could start to be rolled out before the year-end.

But Brent was down 75 cents at $47.86 a barrel by 0918 GMT, after earlier falling by $1. The contract rose around 1.6% in the previous session.

West Texas Intermediate crude fell 72 cents to $44.99 a barrel, after gaining 1.8% on Wednesday.

"Despite a number of strong fundamentals rallying the markets, especially vaccine development supporting oil, bearish concerns remains," said Avtar Sandu, senior commodities manager at Phillip Futures.
