US crude rose by 10¢ to stand at $85.54 and Brent crude stood at $109.26 a barrel as investors hoped the US Federal Reserve would inject fresh stimulus to boost the biggest oil consumer’s economy.

Uncertainty over the Libyan conflict and a force majeure by Royal Dutch Shell on Bonny Light sweet crude also affected oil prices, reports Reuters.

Shell was forced to shut in its Nigerian Bonny Light crude exports to repair pipeline damage caused by hacksaw attacks.

Meanwhile, US stockpiles continue to fall. Inventories dropped 3.3 million barrels in the week to 19 August against analyst forecasts for an 800,000 barrel rise.
