World oil prices struck 2016 high points this week as a weaker dollar attracted buyers to a market struggling to overcome a global supply glut. Dollar-denominated oil has become more attractive for buyers of rival currencies despite lingering concerns about excess output, thanks to the US unit falling heavily, particularly against the yen. The dollar's fall comes as the US Federal Reserve held interest rates unchanged at its policy meeting on Wednesday, signalling it was in no hurry to raise borrowing costs.–AFP
