Gold prices rose yesterday on a weaker dollar and were on course for their biggest monthly rise since August, raising the possibility of a climb toward last year\'s record high of just over $1,900 (Dh6,973) per ounce. Sentiment for gold at the end of January compares starkly with late December, when prices dropped by more than 10 per cent in their biggest monthly fall since the collapse of Lehman Brothers in an investor dash for cash. A $400 (Dh1,468) price drop from last September\'s record $1,920.30 had left investors questioning whether gold had ended an 11-year rally. Gold was up 0.6 per cent at $1,740.80 an ounce by 1143GMT, having earlier touched $1,744.80 — its highest since mid-December and up some 11.2 per cent on the month to date.

A top US Federal Reserve official said on Monday he would have preferred a more optimistic statement on the US economy, after the central bank painted a grim picture of the recovery.
