Oil climbed in thin trade today after falling amid concerns about the US economy and the strengthening dollar.
US light sweet crude for January rose 45 cents to $92.70 a barrel by 6.46am after falling by $2.14 a day ago, halving gains from Wednesday when the market was buoyed by a US oil stock draw and a global central bank cash injection.
London Brent crude rose 68 cents to $92.80.
Oil prices touched a two-week high of $94.85 a barrel on Wednesday and Thursday, which may have triggered the reversal.
Fears that the problems in credit markets could push the United States into a recession have roiled financial markets in recent weeks.
This week's fresh moves by the US Federal Reserve and other major central banks, aimed at restoring confidence to world credit markets, failed to sweep the concerns away.
