Increasing US oil supplies could slow market really - Brent up 17% this year
Brent crude eased towards US$126 on Wednesday as expectations for a build in US crude inventories offset improving economic sentiment in the world's top oil consumer.
Brent crude fell 20 cents to US$126.02 a barrel by 0245 GMT, after settling at an 11-month high of US$126.22 on Tuesday. US crude eased seven cents at US$106.64.
"The US economy seems more buoyant, so that is keeping the market up," said Tony Nunan, a risk manager at Mitsubishi Corp. "What will bring oil prices off is if we get strong builds in inventories. Supply seems to be sufficient, with OPEC producing at high levels to make up for any shortfall."
