Oil hits $98 on weakening dollar
The ever-weakening dollar and fresh worries about winter fuel supplies have sent US oil prices to $98 a barrel.
The effect was worsened by storms in the North Sea on Tuesday, which disrupted supply as prices inched closer to the $100-a-barrel mark.
The weaker dollar has been driving up oil prices because some investors have been using the commodity as an alternative to holding dollars.
On the other hand, it makes oil relatively cheaper for anybody outside the US.
In recent sessions, record highs have been followed by falls of at least $1 a barrel. Nonetheless, some analysts say that $100-a-barrel oil is inevitable.
"We're going to get $100 before too long," said Kevin Norrish of Barclays Capital.
